Answer:
A = 80π
Step-by-step explanation:
Area of a circle is A = πr²
Area of the the largest circle - Area of the smaller circle = the shaded part.
Largest circle - Area of the smaller circle = Shaded part of circle
A = π(12)² - A = π(8)²
144π - 64π = 80π

An office clerk earns $120 for two 4-hour work shifts. How much will she earn
for 15 hours of work?
Answer:
$225
Step-by-step explanation:

$15 every 1 hour
Money for 15 hours: 15 x 15 = $225
The office clerk earns $225 for 15 hour of work .
What is unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
According to the question
An office clerk earns $120 for two 4-hour work shifts.
i.e
In 2 * 4-hour work shifts office clerk earns = $120
or
In 8 hour work shifts office clerk earns = $120
Now ,
By using unitary method
In 1 hour work shifts office clerk earns = $[tex]\frac{120}{8}[/tex]
= $15
Therefore, for 15 hours of work shifts office clerk earns = $15 * 15
= $225
Hence, The office clerk earns $225 for 15 hour of work .

A middle school took all of its 6th grade students on a field trip to see a play. The students filled 1917 seats, which was 45% of the total number of seats in the theater. How many total seats were in the theater?
Answer:
4260 seats in the theater
Step-by-step explanation:
We write the equation 0.45x=1917, with x representing the total number of seats.
Multiply both sides by 100, we get 45x=191700.
Divide both sides by 45, we get x=191700/45
x=4260.
There are 4260 seats in the theater.
The total number of seats is the theater is 4,260.
Percentage:
The percentage is a ratio or fraction of 100 and can be calculated with the formula
Percentage = [tex]\frac{parts}{whole}.100[/tex]
How to calculate percentage?Here we have given that the 1917 seats is 45% of the total seats
Let the total number of seats available in theater is = x
Then 45 % of x = 1917
0.45 x = 1917
Multiply both the sides by 100 we have
45 x = 1917x100
x = [tex]\frac{191700}{45}=4260[/tex]
The final answer is 4,260 seats

The equation has the same solution as w / 3.9 = 3 is w+0.6=1.9
Given:
w / 3.9 = 3
cross multiply
w × 3 = 3.9
3w = 3.9
divide both sides by 3
w = 3.9 / 3
w = 1.3
Check all that applies
A. w+0.6=1.9
w = 1.9 - 0.6
w = 1.3
B. w-0.6 = 11.1
w = 11.1 + 0.6
w = 11.7
C. w+1.03=2.93
w = 2.93 - 1.03
w = 1.9
D. w-1.03=8.24
w = 8.24 + 1.03

the product of seven non-zero factors. of which only three are positive. is
a) positive
B) negative
c) null
The answer is A
Step-by-step explanation: This is one of those sneaky questions where you think there is no definite answer, but don't despair. There is an answer. You have 7 numbers 3 of them are positive which means greater than 0. Let's pick them 345 = 60 That part's easy. Those 3 numbers give a plus result. Now try the other 4 numbers -3 -2 - 1-4 Do you see what's going to happen. You have -3* - 2 = 6 then you get - 1*-4 = 4 All of a sudden you get a positive result 6 * 4 = 24 60 * 24 = 1440 So the answer is any 3 plus numbers multiplied by 4 minus numbers gives a plus result.
Of 7 non-zero factors, 3 are positive, so the other 4 are negative. Multiplying two negatives gives a positive number. So on its own, the product of all the negatives is positive, and multiplying by the other 3 positive numbers makes the overall product positive.
