Determine the value of x
Answers
Answer:
x = 13
Step-by-step explanation:
Add 3x and 4x - 1 together to get 7x-1. Since the angle on the bottom right is 90 degrees, we can safely assume that the remaining angles add up to 90 degrees. Add 1 on both sides to get 7x = 91. Divide 7 on both sides to get 13 as your x value.
To plug in the x value, plug 13 in. The one on the bottom left should equal to 39 degrees and the one on the top right should equal to 51 degrees.

Answer:
m + b ≤ 153m + 5b ≥ 60Step-by-step explanation:
There are two requirements:
the need to limit timethe need for a certain incomeEach of these gives rise to an inequality.
The variables in the problem are the numbers of hours spent at each activity. If we let m represent hours mowing, and b represent hours babysitting, then we have ...
m + b ≤ 15 . . . . . . . . total hours can be no more than 15
The amount of money earned mowing is 3m. The amount of money earned babysitting is 5b. We want the total earned to be at least $60, so the other constraint can be expressed as ...
3m +5b ≥ 60 . . . . . . earnings must be at least $60
__
Then the system of inequalities is ...
m + b ≤ 153m + 5b ≥ 60A ball is thrown vertically upwards from a height of 8 ft with an initial velocity of 30 ft per second. How high will the ball go? Note that the acceleration of the ball is given by a(t)= -32 feet per second per second
a) 50.1875 ft
b) 18.5469 ft
c) 53.1875 ft
d) 22.0625 ft
e) 34.1875 ft
Answers
Answer:
c) [tex]22.0625\ \text{ft}[/tex]
Step-by-step explanation:
u = Initial velocity = 30 ft/s
s = Displacement
v = Final velocity = 0
a = Acceleration due to gravity = [tex]-32\ \text{ft/s}^2[/tex]
From kinematic equations we have
[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{0^2-30^2}{2\times -32}\\\Rightarrow s=14.0625\ \text{ft}[/tex]
Distance the ball will reach from the height from which the ball is thrown is [tex]14.0625\ \text{ft}[/tex].
Distance of the ball from the ground is [tex]8+14.0625=22.0625\ \text{ft}[/tex].

How do you convert Standard Form of an Equation to Slope Intercept Form?
Answers
Answer:
In order to go from one form to another, all you have to do is change the order of the given numbers. First you want to move the Ax to the opposite side of the equation, by either adding or subtracting it. At this point your equation will be set up By = -Ax + C. Then you want to divide the B from the By and the rest of the equation. Therefore you will have y = - Ax/B + C/B. This is the same thing as the slope-intercept form, just a few of the letters are different.
8x + 4y = 16
8x + 4y = 16 first subtract 8x
4y = -8x + 16 then divide all by 4
y = -2x + 4 slope form
Mohan had 80 pens . He give 30 pens to his friend. What fraction of pens he gave to his friend ?
Answers
Answer:
3/8
Step-by-step explanation:
He has a total of 80 which is your bottom number
30 is what he gave away so that is her top number
30/80 you simplify or reduce that down by dividing both top and bottom number by 10
30÷10=3
80÷10=8
your answer is 3/8
Mohan has total 80 pens from which he gave 30 pens to his friend, then the fraction of pens he gave to his friend will be 8/3.
What is a fraction?In mathematics, a fraction is represented by a specific number that designates a portion of an entire.
A fraction is a piece or section of a whole, whereby a can have been any number, a particular value, or an object.
As per the information given in the question,
Total number of pens = 80
Pen's given to his friend = 30

Answer:
4. a. y = 2x
b. she will need 12 packs of cashews to 24 cans of peanuts to make the mix.
5. a. YES
b. y = 2.5x
c. $30
d. 24 pounds
e. See attachment
Step-by-step explanation:
4.a. packages of cashews = x
Cans of peanuts = y
The equation that represents the relationship between x and y can be expressed in slope-intercept form as y = mx
Slope = m,
Finding slope (m) using two pairs (1, 2) and (2, 4):
Slope = ∆y/∆x = (4 - 2)/(2 - 1) = ²/1 = 2
m = 2.
To write the equation, substitute m = 2 into y = mx
The equation would be:
y = 2x
b. The ordered pair (12, 24) in the context of the problem means she will need 12 packs of cashews to 24 cans of peanuts to make the mix.
5. a. The cost of candy is proportional to the amount of candy because: 5/2 = 7.5/3 = 12.5/5 = 2.5 = constant of proportionality/unit rate
b. An equation can be written to show the proportional relationship in the form of y = mx.
Where, m = constant of proportionality/unit rate
x = amount of candy
y = cost on dollars
Thus, substitute m = 2.5 into y = mx
The equation would be:
y = 2.5x
c. To find how much it would cost (y) for 12 pounds of candy (x), substitute x = 12 into y = 2.5x to find y.
Thus:
y = 2.5(12) = 30
It would cost $30 for 12 pounds of candy
d. To find the maximum amount of candy (x) you can buy with $60 (y), substitute y = 60 into y = 2.5x
Thus:
60 = 2.5x
Divide both sides by 2.5
60/2.5 = 2.5x/2.5
24 = x
x = 24
Maximum amount of candy you can buy with $60 is 24 pounds of candy.

Solving systems of equations using substitution/eliminationStandard Form: ax² + bx + c = 0Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]Step-by-step explanation:
Step 1: Define Systems
xy = 289
x - y = 20
Step 2: Rewrite Systems
x - y = 20
Subtract x on both sides: -y = 20 - xDivide -1 on both sides: y = x - 20Step 3: Redefine Systems
xy = 289
y = x - 20
Step 4: Solve for x
Substitution
Substitute in y: x(x - 20) = 289Distribute x: x² - 20x = 289Rewrite [SF]: x² - 20x - 289 = 0Define variables: a = 1, b = -20, c = -289Substitute [QF]: [tex]x=\frac{20\pm\sqrt{(-20)^2-4(1)(-289)} }{2(1)}[/tex]Exponents: [tex]x=\frac{20\pm\sqrt{400-4(1)(-289)} }{2(1)}[/tex]Multiply: [tex]x=\frac{20\pm\sqrt{400+1156} }{2}[/tex]Add: [tex]x=\frac{20\pm\sqrt{1556} }{2}[/tex]Simplify: [tex]x=\frac{20\pm 2\sqrt{389} }{2}[/tex]Factor GCF: [tex]x=\frac{2(10\pm \sqrt{389} )}{2}[/tex]Divide: [tex]x=10\pm \sqrt{389}[/tex]Step 5: Solve for y
Possibility 1: x = 10 + √389
Define equation: x - y = 20Substitute in x: (10 + √389) - y = 20Isolate y term: -y = 20 - (10 + √389)Isolate y: y = (10 + √389) - 20Combine like terms: y = -10 + √389Evaluate: y = 9.72308Possibility 2: x = 10 - √389
Define equation: x - y = 20Substitute in x: (10 - √389) - y = 20Isolate y term: -y = 20 - (10 - √389)Isolate y: y = (10 - √389) - 20Combine like terms: y = -10 - √389Evaluate: y = -29.7231Step 6: Identify Solutions
Possibility 1:
x = 10 + √389, y = -10 + √389
x = 29.7231, y = 9.72308
Possibility 2:
x = 10 - √389, y = -10 - √389
x = -9.72308, y = -29.7231
Andrew has a loyalty card good for a 16% discount at his local pharmacy. What would his total in dollars and cents be, after the discount and before tax, if the total cost of all the items he wants to buy is $38.50? Round to the nearest cent.
Answers
Answer:
Hi there! The answer is $32.34. Hope this helps! c:
Step-by-step explanation:
First thing to do is calculate how much 16% of $38.50 is. You can do this by doing the following:
$38.50 * 0.16 = $6.16
Thus, 16% of $38.50. Since this is a discount, you must subtract $6.16 from $38.50.
$38.50 - $6.16 = $32.34

if y= x+3/6-x, what is the value of y when x =7i?
Answers
Answer:
Option (2)
Step-by-step explanation:
Given : y = [tex]\frac{x+3}{6-x}[/tex]
If x = 7i
y = [tex]\frac{7i+3}{6-7i}[/tex]
By simplifying denominator of the given rational expression,
y = [tex]\frac{7i+3}{6-7i}\times \frac{6+7i}{6+7i}[/tex]
y = [tex]\frac{(7i+3)(6+7i)}{6^2-(7i)^2}[/tex]
y = [tex]\frac{7i(6+7i)+3(6+7i)}{36-49i^2}[/tex]
y = [tex]\frac{42i+49i^2+18+21i}{36+49}[/tex] [Since, i² = (-1)]
y = [tex]\frac{63i-49+18}{85}[/tex]
y = [tex]\frac{63i-31}{85}[/tex]
y = [tex]-\frac{31}{85}+\frac{63}{85}i[/tex]
Therefore, Option (2) is the correct option.
