The area of a circle (A) is given by the formula A= pi*r to the second power, where r is the radius. The formula to find r is _.

podryga [215]

Answer:

The correct option for the first blank is A. (A/pi) to the power of 1/2

The correct option for the second blank is A. 4.15

Step-by-step explanation:

1. Let's review the information provided to us to answer the questions correctly:

Area of a circle (A) = π * r², where r = radius

2. The formula to find r is ________________:

A = π * r²

r² = A/π

√r² = √ A/π

r = √A/π

r = A/π∧(1/2) or (A/pi) to the power of 1/2.

The correct option for the first blank is A. (A/pi) to the power of 1/2

3. if A = 54 centimeters squared, and pi = 22/7, r is _ centimeters.

We use the formula we got for the first blank, this way:

r = (A/pi) to the power of 1/2

Replacing with the real values, we have:

r = (54/(22/7)) to the power of 1/2

r = 17.2 to the power of 1/2

r = √17.2 = 4.15 (Rounding to the next hundredth)

The correct option for the second blank is A. 4.15

kakasveta [241]

Answer:

The expression that represents the total time Louis spends commuting to and from the gym each day is 8(x-2y)

Step-by-step explanation:

Given that the time Louis spends commuting to the gym can be represented by two expressions:

Time to gym: $2x-6y\hfill (1)$

Time from gym: $6x-10y\hfill (2)$

To find the expression that represents the total time Louis spends commuting to and from the gym each day :

The total time Louis spends commuting to and from the gym each day is equal to the sum of the Time to gym and Time from gym

Total time Louis spends commuting to and from the gym each day=2x-6y+6x-10y

=8x-16y

=8(x-2y)

Therefore Total time Louis spends commuting to and from the gym each day is 8(x-2y)

The expression that represents the total time Louis spends commuting to and from the gym each day is 8(x-2y)

In 2007, the FDIC’s insurance limit was $100,000 per person per bank. If Sam had a $150,000 savings account and $80,000 checking

Oksi-84 [34.3K]

Alright, let's look at each individual bank. For each bank, only up to 100k is insured.

Bank J = 150,000+80,000 -> 230,000 but only 100,000 is insured.
Bank K = 95,000 -> 95,000 insured.
Bank L = 200,000 -> 100,000 insured.
Adding those together...
100,000 + 95,000 + 100,000 = 295,000
So, A is the correct answer.
