A circular swimming pool has a radius of 20 feet. A fence is going to be built so that there is a 4-foot space around the entire pool. What is the length of the fence? Sunitha solved the problem as shown. A circle with radius 20 feet. A larger circle is 4 feet larger than the smaller circle. Radius = 24 feet. Circumference = 24 pi. What was her error? She should have used 12 in the formula, not 24. She forgot to multiply the radius by 2 in the formula. She did not add the additional fence length to the pool’s radius. She should have used 4 ft in the formula.
Answer:
she forgot to multiply the radius by 2 in the formula (B)

ran 6 kilometers on Tuesday. How many
total kilometers did John run?
Answer:
11 kilometers

Since there are 1,000 m in 1 km, John ran 5 km on Monday. Combine that with the 6 km he ran on Tuesday, and you get 11 km in total.
Answer:
11 kilometers
Step-by-step explanation:
1000 meters=1 kilometer
5000÷1000=5
5+6=11
Given the definitions of f(x) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x^2 + 6x – 8
I don’t need work I am just looking for the answer !
gf(x) = g(x^-1) = x^2 + 6x - 8
f(x) = 2x - 10
gf(x) = 6 ( 2x - 10) - 8
gf(x) = 12x- 60 - 8
gf(x) = 12x -68
gf(5) = gf(x) = 12x - 68
gf(5) = 12(5) - 68
gf(5) = 60 - 68
gf(5) = -8
Two geometrically similar jugs have volumes of 1000 cm3and 512 cm3.They have circular bases. The diameter of the base of the larger jug is 9 cm.
Complete Question
Two geometrically similar jugs have volumes of 1000 cm³and 512 cm³.They have circular bases. The diameter of the base of the larger jug is 9 cm.
Calculate the diameter of the smaller jug.
Answer:
7.2 cm
Step-by-step explanation:
To solve the above question,we have the proportion
Smaller volume/ Larger volume = (Smaller diameter/ Larger diameter)³
We are to find the smaller diameter
Hence our formula is give as
Cube root(Smaller volume/ Larger volume)= Smaller diameter/ Larger diameter
=cube root( 512/1000) = x/9
= 8/10 = x/9
Cross Multiply
10x = 8 × 9
10x = 72
x = 72/10
x = 7.2cm
Therefore, the diameter of the second jug is 7.2 cm

The average distance from the Earth to the moon is 238,855 miles. What is the distance rounded to the nearest thousand?
Answer:
239,000
Step-by-step explanation:
Look at the digit to the right of the place you're rounding to. In this case, we are rounding to the thousands, so we look at the digit in the hundreds place. It's 8, which is above 5 (5 and above you round up. 4 and below, you round down). Because the 8 is above 5, we go back to the thousands place and bump the number (8) up one (to 9).

What is 589 divided by 31 with remainder?
Answer:
19 remainder 0
Step-by-step explanation:
When we divide 589 by 31 we get remainder 0.
Here we have to find the remainder when 589 is divided by 31
In order to this proceed with division,
Since we know that,
When the numerator is equal to or more than the denominator, the fraction is said to be inappropriate. It always has a value of one or higher. Since mixed fractions are simpler to understand, improper fractions are typically expressed in simplified mixed number form.
Now

which of the following decimal has highest value is a 0.5 b 0.12 c 0.17 d 0.8
Answer:
d 80 cents or 0.8
Step-by-step explanation:
Change them all to money. Then look at it again.
0.5 = 50 cents
0.12 = 12 cents
0.17 = 17 cents
0.8 = 80 cents.
You get each of them by starting with a dollar. A dollar has 100 cents.
So 0.5 of a dollar is 1/2 a dollar.
1/2 a dollar is 0.5 * 100 = 50 cents
0.17 * 100 = 17 cents
0.12 * 100 = 12 cents
0.8 * 100 = 80 cents
The largest one is 8
Answer d) 0.8
Step-by-step explanation: Here is a tip, when you see a decimal like 0.5 compared to a bigger looking one like 0.12 add a 0 to the end. It will still have the same value and you won't be as confused.
0.80> 0.50> 0.17> 0.12

Answer:
-79.78 (really stinking cold)
Step-by-step explanation:
Solving the equation will go like this:
5/9(F - 32) = -62.1
multiply both sides by 9 to get rid of the fraction
5 (F - 32) = -558.9
divide both sides by 5
F - 32 = -111.78
add 32 to both sides
F = -79.78

A car was purchased for $24,000. Its value is predicted to decay exponentially, decreasing by 13% each year. Write an equation to determine the value of the car.
Answer:
y= P(0.87)^t
Step-by-step explanation:
Given data
Price P= $24,000
Rate of decay in price= 13%
The expression in terms of y, p and t is
y=P(1-r)^t
y= P(1-0.13)t
y= P(0.87)^t
