Answer:

177.475 $inches^{2}$

Step-by-step explanation:

Since the formula for finding the area of a full circle is A = π $r^{2}$ , area equals pi times radius squared, we fill out the formula and solve.

A: unknown

Pi: 3.14

Radius: diameter is 12, so you divide it by 2, which is 6.

A = 3.14 x 6 squared.

using pemdas, you do exponents first,

A = 3.14 x 36

A ≈ 113.04

Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,

113.04/2

= 56.52

So, the area of the semicircle is 56.52 $inches^{2}$

This is my 3rd answer as a helper, I hope it helped!

Answer:

56.52

Step-by-step explanation:

This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52

i think it is 40%

Step-by-step explanation:

she made 2/5 shots so

2/5*2=4/10

i times it by 2 because its out of 100

4/10*10=40/100

then i times it by 10 to get to 100

The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of

Nesterboy [21]

Answer:

$P=400000(2^t)-40000t$

Step-by-step explanation:

The initial number of mosquitoes is 400000, and they double each day. This represents an exponential growth equation. If t represent days and P represent the population of the mosquitoes, hence this can be represented by the equation:

$P=400000(2^t)$

Also, the predators eat the mosquitoes at a rate of 40,000 mosquitoes/day. This means that each day, the mosquitoes reduce by 40000t, therefore this can be represented by:

$P=400000(2^t)-40000t$

Sally gets paid $15.00 dollars per hour for a 40-hour work week and y dollars for each hour she works over 40 hours. What is the

Anna35 [415]

The equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

Step-by-step explanation:

Sally gets paid $15.00 dollars per hour for a 40-hour weekly work.
She gets y dollars for each extra hour she works over 40 hours.

The equation can be framed as :

Let,

x be the total pay she could get for 48 hours.
The amount she earned for 40 hours = 40 × $15 ⇒ $600
The amount she earned for extra hours = 8 × y ⇒ 8y

The equation is given as,

Total earnings = amount earned for 40 hours + amount for extra 8 hours.

⇒ x = 600 + 8y

Therefore, the equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.
