Answer:
x = 43
Step-by-step explanation:
First, make the equation which is
x + 49 + 88 = 180
Next, add 49 + 88 which is 137
Now you have x + 137 = 180
Subtract 137 from both sides and you get your final answer:
x =43

Erin earns $2 200 per month her deduction amount to 28% of her paycheck. How much does she take home each month
Answer:
1584
Step-by-step explanation:
The take-home salary would be $1584 each month if Erin earns $2200 per month her deduction amount to 28% of her paycheck.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Erin earns $2200 per month.
The deduction amount to 28% of her paycheck.
Let's assume the 28% is deducted from the monthly salary.
The total dedcution = 28% of 2200
The total dedcution = (28/100)x2200
The total dedcution = 0.28x2200
The total dedcution = $616
Total net amount = Take home = 2200 - 616
Take home = 2200 - 616
Take home = $1584
Thus, the take-home salary would be $1584 each month if Erin earns $2200 per month her deduction amount to 28% of her paycheck.

Carter is creating quilt pieces in the shape of a kite as shown below. One of the kite diagonals measures 6 inches, and the area of each piece must be between 20 and 25 square inches.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]d_1 =6in[/tex] --- the first diagonal
[tex]Area = (20in^2,25in^2)[/tex]
The question is incomplete, as the image of the kite and what is required are not given
However, a possible question could be to calculate the length of the other diagonal
Calculating the length of the other diagonal, we have:
[tex]Area = 0.5 * d_1 * d_2[/tex]
Make d2 the subject
[tex]d_2 = \frac{Area }{0.5 * d_1}[/tex]
Multiply by 2/2
[tex]d_2 = \frac{2 * Area }{2* 0.5 * d_1}[/tex]
[tex]d_2 = \frac{2 * Area }{1 * d_1}[/tex]
[tex]d_2 = \frac{2 * Area }{d_1}[/tex]
When Area = 20, we have:
[tex]d_2 = \frac{2 * 20}{6}[/tex]
[tex]d_2 = \frac{40}{6}[/tex]
[tex]d_2 = 6.67[/tex]
When Area = 25, we have:
[tex]d_2 = \frac{2 * 25}{6}[/tex]
[tex]d_2 = \frac{50}{6}[/tex]
[tex]d_2 = 8.33[/tex]
So:
[tex]d_2 = (6.67,8.33)[/tex]
This means that the length of the other diagonal is between 6.67in and 8.33in
Find the value of z.
Answer:
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.\

Find the value’s of x given that f(x) = x^2 - 2x - 3 and f(x) = 5
Answer:
4 and - 2
Step-by-step explanation:
f ( x ) = x^2 - 2x - 3
f ( x ) = 5
x^2 - 2x - 3 = 5
x^2 - 2x - 3 - 5 = 0
x^2 - 2x - 8 = 0
x^2 + 2x - 4x - 8 = 0
x ( x + 2 ) - 4 ( x + 2 ) = 0
( x - 4 ) ( x + 2 ) = 0
x - 4 = 0
x = 4
x + 2 = 0
x = - 2
x has 2 values,
x = 4, - 2
math question need help with it
Answer:
c- 4 x 10^7
Step-by-step explanation:
for scientific notation, the first number can not be greater than 9
so you have to split your number into a decimal
37,250,000
3.7250000
so the first part of your equation is 4 because the 7 rounds up the 3
then, there are 7 digits after the decimal, so that is your exponent
it is also positive.
so your final answer is
4 x 10^7 :)
The relation defined by the set of ordered
pairs
{(0,3), (2,1),(3,0).(-1,2), (0,5),(-2,5)}
is not a function. Deleting which of the
ordered pairs will make the resulting set a
function?
a. (0,3)
c. (3.0)
b. (2.1)
d. (-1,2)
Answer:
a: (0,3)
Step-by-step explanation:
the input 0 currently has two outputs, deleting one, (0,5), would cause the set of ordered pairs to become a function

A. 24°
B. 66°
C. 64°
D. 26°
Answer:
C
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{7}{16}[/tex] , then
θ = [tex]cos^{-1}[/tex] ([tex]\frac{7}{16}[/tex] ) ≈ 64° ( to the nearest degree )

An elevator descends into a mine shaft at the rate of 5 m/min. If the descend starts from 15m above the ground, by how long will it take to reach 350 m deep from the ground?
Answer:
Step-by-step explanation:
First we need to do 350 - 15 since 350 is our total and we already started at 15m.
Next divide the remainder (335) by 5 because that’s how fast we are moving, the final answer is 67 minutes.
