Answer:
20.3π cm
Step-by-step explanation:
Area of a circle = 324 square cm
πr² = 324
[tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]
r = 10.15 cm
Circumference = 2πr
= 2 * π * 10.15
= 20.3π cm

The perimeter of the trapezoid-shaped window frame is 23.59 feet. Write and solve an equation to find the unknown side length x (in
feet).
Answer:
[tex] 5.62 + 3.65 + 5.62 + x = 23.59 [/tex]
[tex] x = 8.7 ft [/tex]
Step-by-step explanation:
Perimeter of the trapezoid-shaped window = sum of all the sides of the window frame
Thus, the equation to find the unknown side length, x, would be:
✔️[tex] 5.62 + 3.65 + 5.62 + x = 23.59 [/tex]
Solve for x
[tex] 14.89 + x = 23.59 [/tex]
Subtract 14.89 from each side
[tex] 14.89 + x - 14.89 = 23.59 - 14.89 [/tex]
✔️[tex] x = 8.7 ft [/tex]

Answers:
Monthly gross pay = $7650.68
Annual gross pay = $91808.16
Explanation:
To get the monthly gross pay, you double the semi-monthly gross pay. In other words, you multiply by 2.
Once you know how much you earn per month, you multiply that by 12 to get your annual pay.
The term "gross" in financial terms means the amount of money before taxes and other fees apply. The net pay is after taxes and other fees are deducted from your paycheck. This means the net pay is going to be smaller than the gross pay.

Find the area of each figure.
10 mm
15 mm
B mm
30 mm
Answer:370mm^3
Step-by-step explanation:
You would first find the area of the whole rectangle without the hole, so (15)(30)=450
Next find the area of the hole, (8)(10)=80
To find the area you must subtract the area of the hole from the rectangle.
450-80=370

1. In a supermarket, each orange costs $3, and each apple costs $2. If you want to spend
exactly $45, write an equation in standard form modeling this situation. Let o represent
the number of oranges you buy, and a represent the number of apples you buy.
Answer:
3o + 2a = $45 ( you can buy 9 oranges and 9 apples)
Step-by-step explanation:
First I divided 45 by 3 and I got 15 so now I know that 15 is the highest amount of oranges I can buy without going over $45. I also know that 15 cannot be an answer because I also have to buy apples.
Then I divided 45 by 2 and 22 was the highest whole number.
Now I would play trial and error BUT i know that the number for oranges have to be less that 15 and the number for apples has to be less than 22.
3 times 9 equals 27 (oranges)
45 - 27 = 18
2 times 9 equals 18 (apples)
3o+2a =$45 is the equation in standard form modeling this situation.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in a supermarket, each orange costs $3, and each apple costs $2.
Let o represents the number of oranges you buy
and a represent the number of apples you buy.
If you want to spend exactly $45
We have to find the equation to model this situation
3o+2a =$45
Hence, 3o+2a =$45 is the equation in standard form modeling this situation.

Step-by-step explanation:
We are given:
3[tex]\frac{1}{5}x[/tex] + 10[tex]\frac{7}{9}x[/tex] - 2[tex]\frac{2}{5}x[/tex] - 10[tex]\frac{8}{9}x[/tex]
Concepts used:
Evaluating Mixed fractions and Adding like terms
Simplifying the Mixed Fractions:
to simplify these mixed fractions, we will multiply the whole number part with the fraction's denominator and add that to the numerator.
The number formed will be given the same denominator as of the fraction part in the number
After simplifying these mixed fraction, we get:
[tex]\frac{16}{5}x + \frac{97}{9}x - \frac{12}{5}x - \frac{98}{9}x[/tex]
Adding and Subtracting the like terms:
to simplify our calculations, we will pair the numbers with the same denominator
[tex](\frac{16}{5}x - \frac{12}{5}x) + (\frac{97}{9}x - \frac{98}{9}x)[/tex]
Simplifying the terms in the brackets
[tex]\frac{4}{5}x - \frac{1}{9}x[/tex]
Taking the LCM and simplifying
[tex]\frac{36}{45}x - \frac{5}{45}x[/tex]
Since the denominators are equal, the numerators can now be subtracted
[tex]\frac{31}{45}x[/tex]
Therefore, simplifying the given series of number gives us 31x/45
