How do you find this??

The sale price of the backpack is $25.50.

The original price of the sweatshirt is $40.

From the information, the sale price of every item in a store is 85% of its usual price and the usual price of a backpack is $30.

The sale price will be:

= Percentage × Original price

= 85% × $30

= $25.50

The sale price of a sweatshirt is $34, its original price will be:

= 85% × x = $34

0.85x = $34

x = $34 / 0.85

x = $40

The coordinates along the directed line segment is (-4, 5/3)

This involves dividing a line into proportional ratios

The points are given as:

A  = (-7, 2)

B = (2, 1)

The ratio on the segment can be represented as;

m : n = 1 : 2

So, we have the coordinates of the point that lies along the directed line segment to be

Point = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)

So, we have:

Point  = 1/(1 + 2) * (1 * 2 + 2 * -7, 1 * 1 + 2 * 2)

Evaluate

Point  = 1/3 * (-12, 5)

Evaluate the products

Point  = (-4, 5/3)

Hence, the coordinates of the point is (-4, 5/3)

The distance between the Earth and the Sun is 1.5 extend eight kilometers, and the distance between Mars and the Sun is 2.2 8 X 10 eight kilometers. The scientific notation for the distance between Earth and Mars is 3.78 x 10^8 km.

The length of the line connecting two points is the distance between them. If the two points are on the same horizontal or vertical line, the distance can be calculated by subtracting the non-identical coordinates.

Distance is defined as an object's total movement without regard for direction. Distance can be defined as how much ground an object has covered regardless of its starting or ending point.

Given,

The distance between Earth and Sun = 1.5 x 10^8 km

The distance between Sun and Mars = 2.28 x 10^8 km

Therefore the distance between Earth and Mars =

(1.5 x 10^8 + 2.28 x 10^8) km

= (1.5 + 2.28) x 10^8 km

= 3.78 x 10^8 km (Ans)

We got the factors which is prime numbers = 2 × 2 × 2 × 3

The technique of expressing all numbers as the product of primes is known as prime factorization. So, let's take something like the number 20 as an example. That can be divided into two components. "Well, that's 4 times 5," we can respond. Observe that 5 is a prime number.

For e.g, let's take number of 24 and factor it,

24/2 = 12

12/2 = 6

6/2 = 3

3/3 = 1

We got the factors which is prime numbers = 2 × 2 × 2 × 3

By solving a linear equation, we will see that the two consecutive integers are -8 and -7

We know that the sum of an integer and 6 times the next consecutive integer is -50.

So if x is the integer, x + 1 will be the next consecutive integer, then we can write the equation:

x + 6*(x + 1) = -50

So we need to solve a linear equation, it will give:

x + 6x + 6 = -50

7x + 6 = -50

7x = -50 - 6

7x = -56

x = -56/7 = -8

Then the next integer is:

y=-2/5x-5 is the equation of a line into slope- intercept form

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given equation is 6x + 15y = -75

six x plus fifteen y equal to minus seventy five

6x + 15y = -75

Subtract 6x from both sides

6x+15y-6x=-75-6x

15y=-75-6x

Divide both sides by 15

y=-75/15 -6/15 x

y=-5-2/5x

y=-2/5x-5

Hence y=-2/5x-5 is the equation of a line into slope- intercept form

Answer:

Your answer is [tex]10x + 5[/tex]

Step-by-step explanation:

A coefficient is the number before the variable, in this case, 10.

A constant is the number with no variable attached to it, in this case, 5.

( 5,0 ) and ( 0,4 ) are the x and y-intercept of the function 4x + 5y = 20 respectively.

The intercept of a line on a graph is simply the point at which it intersects either the x-axis or y-axis.

Given the data in the question;

Now, we find the intercepts of the equation of line, plug in y = 0 and solve for x

4x + 5y = 20

4x + 5(0) = 20

4x = 20

x = 20/4

x = 5

Hence, the x-intercept is ( 5,0 )

For the y-intercept, plug in x = 0 and solve for y

4(0) + 5y = 20

5y = 20

y = 20/5

y = 4

Hence, the y-intercept is ( 0,4 ).

Therefore the x and y-intercept are ( 5,0 ) and ( 0,4 ).

The total yield for an acre, T, in pounds as a function of the number of walnut tree per acre, x is given by T = -1.5x² + 95x.

In order to solve this word problem, we would assign variables to the number of walnut tree per acre and total yield for an acre, and then translate the word problem into algebraic equation as follows:

Mathematically, the total yield for an acre can be calculated by using this mathematical expression:

Total yield for an acre (T) = yield of each tree × number of trees per acre

Substituting the given parameters into the mathematical expression, we have the following;

Total yield for an acre (T) = [50 - 1.5(x - 30)] × x

Opening the bracket, we have:

Total yield for an acre (T) = [50 - 1.5x + 45] × x

Total yield for an acre (T) = 50x - 1.5x² + 45x

Next, we would rearrange the function by collecting like terms and simplifying as follows:

Total yield for an acre (T) = -1.5x² + (50x + 45x)

Total yield for an acre (T) = -1.5x² + 95x

Answer:

3. ∠A = 110°

4. ∠H = 70°

5. ∠D = 70°

6. ∠F = 70°

Step-by-step explanation:

In a parallelogram, adjacent angles are supplementary (sum to 180°).

⇒ ∠A + ∠B = 180°

⇒ ∠A + 70° = 180°

⇒ ∠A = 110°

In a parallelogram, opposite angles are congruent.

⇒ ∠C = ∠A = 110°

⇒ ∠D = ∠B = 70°

If two parallelograms are similar, their corresponding interior angles are congruent.

⇒ ∠A = ∠E = 110°

⇒ ∠B = ∠F = 70°

⇒ ∠C = ∠G = 110°

⇒ ∠D = ∠H = 70°

4. The slope of the line through the points (0, 6) & (20, 14) is  [tex]\frac{2}{5}[/tex]

The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope of a line, or a section of a line connecting two points, is a measure of its steepness.

Or. A line's slope is the ratio of how much y increases as x increases by some amount. The slope-intercept form of an equation is when the equation of a line is written in the form y = mx + b. The slope of the line is given by m. And b is the value of b in the y-intercept point (0, b).

Now, the park has to be fenced along all of its sides. Thus, we need to find the perimeter of the rectangular park.

The perimeter of a rectangle is given as-

Answer:

Workers to be be added to finish the work in 24 hours = 348

Step-by-step explanation:

This is a problem involving inverse proportion

Here the number of days required to complete the job is inversely proportional to the number of workers- the more the workers, the less time it takes

We can state this as:
[tex]D \propto \dfrac{1}{N}[/tex]

where D = time in days required to complete the job and N is the number of workers that can do this in D days

The equation relating D and N can be stated as

[tex]D = k \dfrac{1}{N}[/tex]

This gives us k = D x N  (multiply by N both sides)

where k is a constant known as the constant of proportionality

Given data that D = 30 when N = 12, this constant of proportionality = D x N = 30 x 12 = 360

From the equation of proportionality we also get
N = k/D

So to complete the job in 24 hours = 1 day, substitute 1 for D and 360 for k to get
N = 360/1 = 360 workers

So you will need 360-12 = 348 workers if you expect to  finish the job in 24 hours = 1 day
