wing system of equations. If there is a solution, write your ans 4x+8y=40 6x+3y=6

Answers

Answer 1

The solution of the given system of equations is x = -1 and y = 4.

The given system of equations is 4x + 8y = 40 and 6x + 3y = 6.


To solve this system of equations, we need to use elimination method. We can subtract 6x from both sides of the second equation and subtract 4x from both sides of the first equation. We get:

8y = 40 - 4x and 3y = 6 - 6x


We can now divide both sides of the second equation by 3 to obtain y = 2 - 2x.


We can substitute the value of y from the second equation into the first equation to get 4x + 8(2 - 2x) = 40, which simplifies to -8x = 8. We can solve this equation for x by dividing both sides by -8, resulting in x = -1.


Substituting the value of x into either equation, we can obtain y = 4. So, the solution of the given system of equations is x = -1 and y = 4.

The sum of the digits of a certain two-digit number is 3. Reversing its digits decreases the number by 27. Find the number.

Answers

The number is 30.

What is Addition?

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum

Given that,

The sum of the digits of a certain two-digit number is 3.

Since it is a two digit number, there will be a tens place and a ones place.

Let x be the digit in tens place and y be the digit in ones place.

x + y = 3

The number can also be written as 10x + y, since x is in the tens place.

When the number is reversed, tens place changed to ones place and vice versa.

The reversed number is 10y + x.

Given that the value of the number is decreased by 27 when the digits is reversed.

Original number - 27 = Reversed number

10x + y - 27 = 10y + x

9x - 9y = 27

x - y = 3

Also, we have,

x + y = 3  [Equation 1]

x - y = 3   [Equation 2]

Adding the equations,

2x = 6

x = 6/2 = 3

Substituting in equation 1, y = 0

Hence the number is 30.

Karen invested her savings in two investment funds. The amount she invested in Fund A was 4 times as much as the amount she invested in Fund B. Fund A returned a 4% profit and Fund B returned a 7% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1380?

Answers

Karen invested $6000 in Fund B, and $24000 in Fund A, as the weighted average of the two funds' returns is 5%, yielding a total profit of $1380, and we can use a system of equations to solve for the amounts invested in each fund.

To solve this problem, we can set up a system of equations using the information given.

Let x be the amount invested in Fund B, then the amount invested in Fund A is 4x. The total amount invested is the sum of these two amounts, so we have:

x + 4x = 5x = total amount invested

The total profit from the two funds is given as $1380, which is the sum of the profits from Fund A and Fund B.

We can express these profits using the amounts invested and the respective return rates:

0.04(4x) + 0.07(x) = 0.16x + 0.07x = 0.23x = $1380

Solving for x, we find that x = $6000, which is the amount invested in Fund B. Therefore, the amount invested in Fund A is 4x = $24000.

3. John wants an average bowling score of 215. If he scored 159, 182, 225, 240, 198,
200 and 230 on his first seven games, what must he score on his 8th game to achieve
this average?

Answers

John must score 286 on his 8th game to achieve an average score of 215.

What is an Average?

Average, also known as the mean, is a mathematical concept that represents the central value of a set of numbers. It is found by dividing the sum of the numbers by the total count of the numbers.

To find out what John must score on his 8th game to achieve an average score of 215, we need to use the formula for calculating the average or mean:

Average = (Sum of Scores) / (Number of Scores)

We can use this formula to solve for the unknown score:

215 = (159 + 182 + 225 + 240 + 198 + 200 + 230 + x) / 8

Multiplying both sides by 8, we get:

1720 = 159 + 182 + 225 + 240 + 198 + 200 + 230 + x

Simplifying, we get:

1720 = 1434 + x

Subtracting 1434 from both sides, we get:

x = 286

Therefore, John must score 286 on his 8th game to achieve an average score of 215.

Two angles in a triangle measure 102 and 54. What measure of the third angle?

Answers

Answer:

24

Step-by-step explanation:

The sum of the three angles in a triangle is always 180 degrees.

Let x be the measure of the third angle.

Then we have:

102 + 54 + x = 180

Simplifying the left side:

156 + x = 180

Subtracting 156 from both sides:

x = 180 - 156

x = 24

Therefore, the measure of the third angle is 24 degrees.

    This line has a slope of 5 and a y-intercept of -2. This means we will start at (0, -2) and move five units up for every unit right, or five units down for every unit left.

    For the next equation, it uses a > symbol so we will use a dashed line. This is because it is not equal to, only greater than. Same as the previous. We will graph it as a slope-intercept line, but using a dashed line instead of a solid line.

    This line has a slope of -2 and a y-intercept of positive 5. This means we will start at (0, 5) and move two units down for every unit right, or two units up for every unit left.

1) To find the number of pounds of grass seed needed to cover an area of 140,000 ft2, you need to write a proportion and solve it. Set up the proportion using the given information:

20 lb/10,000 ft2 = x lb/140,000 ft2

To solve for x, multiply both sides of the equation by 140000:

20 lb * 140000/10,000 ft2 = x lb

x = 2800 lb

You will need 2800 lbs of grass seed to cover an area of 140,000 ft2. To find out how many whole bags of seed you will need to buy, divide the total number of pounds by the number of pounds in a bag, which is 20 lbs. You will need to buy 140 whole bags of seed.

x = 3

The x intercept is (3, 0). To find the y intercept, set x = 0:

3(0) + 6y = 9

6y = 9

Answers

The vector that is perpendicular to the tangent vector of the curve at (0, 1, 0) is <1, 0, -1>, or option c

The space curve given is r(t) = sin t i + e^t j + ln(t+1) k. To find the tangent vector of the curve at a given point, we need to take the derivative of the curve with respect to t. The derivative of the curve is r'(t) = cos t i + e^t j + (1/(t+1)) k.

At the point (0, 1, 0), t = 0. So, the tangent vector at this point is r'(0) = cos 0 i + e^0 j + (1/(0+1)) k = <1, 1, 1>.

Now, we need to find which of the given vectors is perpendicular to the tangent vector. Two vectors are perpendicular if their dot product is equal to 0. So, we need to find the dot product of the tangent vector with each of the given vectors and see which one is equal to 0.

a. <1, 1, 1> • <0, 1, 0> = 0 + 1 + 0 = 1 (not perpendicular)
b. <1, 1, 1> • <-1, 0, -1> = -1 + 0 - 1 = -2 (not perpendicular)
c. <1, 1, 1> • <1, 0, -1> = 1 + 0 - 1 = 0 (perpendicular)
d. <1, 1, 1> • <1, -1, 1> = 1 - 1 + 1 = 1 (not perpendicular)
e. <1, 1, 1> • <1, 0, 1> = 1 + 0 + 1 = 2 (not perpendicular)

Therefore, the vector that is perpendicular to the tangent vector of the curve at (0, 1, 0) is <1, 0, -1>, or option c.

This function rule represents the original function f(x) = √x, shifted up 5 units, vertically stretched by a factor of 2, and shifted to the right 3 units.

The function rule for g(x) from f(x) = √x can be found by applying the given transformations to f(x). First, we shift up 5 units by adding 5 to the function. Then, we apply a vertical stretch by a factor of 2 by multiplying the function by 2. Finally, we shift to the right 3 units by replacing x with (x - 3) in the function. The resulting function rule for g(x) is:

g(x) = 2√(x - 3) + 5

The factored form is 2y(x - y) - 11x.

What is factored form?

Factored form of a polynomial is when the polynomial is written as a product of its factors. Each factor is either a polynomial or a number. Factored form is useful for identifying the zeros of a polynomial and for solving polynomial equations.

To simplify the given expression, we need to combine like terms and factor if possible.

First, let's combine the like terms:

x^2 + 3xy - 4y^2 - 6x + 3y - x^2 - xy + 2y^2 - 5x - 3y

= 2xy - 2y^2 - 11x

Next, let's see if we can factor the expression:

2xy - 2y^2 - 11x

= 2y(x - y) - 11x

Since we cannot factor any further, the simplified expression in factored form is:

2y(x - y) - 11x

The number of blueberry muffins that a baker makes each day is 30% of the total number of muffins she makes.
A. On Monday, the baker makes 42 blueberry muffins. What is the total number of muffins that the baker makes on Monday?


B. On Tuesday, the baker makes a total of 60 muffins. How many blueberry muffins does the baker make on Tuesday?

Answers

The baker makes a total of 140 muffins on Monday.

The baker makes 18 blueberry muffins on Tuesday.

What are percentages?

Percentages are a way of expressing a fraction or proportion out of 100. The term "percent" literally means "per hundred." Percentages are commonly used in many areas of everyday life, including finance, science, and statistics.

To express a number as a percentage, it is multiplied by 100. For example, 0.75 is equivalent to 75 percent, since 0.75 x 100 = 75. Similarly, 50 percent is equivalent to 0.5 or 1/2.

Percentages are commonly used to express changes and comparisons. For example, if a product's price increases from $100 to $120, this represents a 20 percent increase in price. If a person scored 80 out of 100 on a test, this represents an 80 percent score.

Percentages are also used to calculate percentages of a total. For example, if a person earned $40,000 out of a total company income of $500,000, their income represents 8 percent of the total income. Similarly, if a person wants to calculate a 20 percent tip on a $50 meal, they would calculate 20 percent of $50, which is $10.

In summary, percentages are a way of expressing a fraction or proportion out of 100, and are commonly used to express changes, comparisons, and percentages of a total in everyday life.

A. Let's assume the total number of muffins the baker makes on Monday to be x.

According to the problem, the number of blueberry muffins that the baker makes is 30% of the total number of muffins.

So, 30% of x is equal to 42:

0.30x = 42

To solve for x, we can divide both sides by 0.30:

x = 140

Therefore, the baker makes a total of 140 muffins on Monday.

B. Let b be the number of blueberry muffins the baker makes on Tuesday.

According to the problem, the number of blueberry muffins is still 30% of the total number of muffins. So, we can set up the equation:

0.30(60) = b

Simplifying the left side:

18 = b

Therefore, the baker makes 18 blueberry muffins on Tuesday.

find the measure of ycg ​

Answers

Answer:

59

Step-by-step explanation:

Opposite angles are equal

C or KCG isn121

Straight line angle is 180

YCG + GCK = 180

YCG = 180- 121

Another method

All the four angles at a point is 360

YCH + HCK + KCG +YCG is 360

C is 121

121 + X + 121 + X = 360

2X + 242 =360

Subract 242 from both sides

2X = 118

Divide both sides by 2 = 59

The value of x from the similar triangles is x = 4

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔQRS

Let the second triangle be ΔLMN

Now , the measure of ∠QRS = measure of ∠NLM

And , the triangles are similar

Now , the corresponding sides of similar triangles are in the same ratio

On simplifying , we get

LM / RQ = LN / QS

( 2x + 4 ) / 8 = 9 / 6

Multiply by 8 on both sides , we get

2x + 4 = ( 3/2 ) 8

2x + 4 = 12

Subtracting 4 on both sides , we get

2x = 8

Divide by 2 on both sides , we get

x = 4

Therefore , the value of x is 4

Hence , the similar triangles are solved

given the figure below with the provided measurements, what is PQ?

Answers

The requried measure of the PQ in the triangle PQT is 16 in.

What are Similar triangles?

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

Here,
A figure of triangles has been shown, ΔPQT and ΔORS.
We have to determine the measure of side PQ.

Since the given triangle is similar to one another, we can apply the property of proportionality between the similar triangles. By which:

PR/PQ = RS/QT
PQ + 4 / PQ = 10/8
8PQ + 32 = 10PQ
2 PQ = 32
PQ = 16 in

Thus, the requried measure of the PQ in the triangle PQT is 16 in.
