How far did the penguin swim?
Give your answer in terms of pi.
9514 1404 393
Answer:
10π meters
Step-by-step explanation:
The circumference of the island is given by the formula ...
C = πd
where d represents the diameter of the circle.
Halfway around is half the circumference, so the distance the penguin swam is ...
1/2C = (1/2)π(20 m) = 10π m
The penguin swam 10π meters.
Answer:
10pi
Step-by-step explanation:
The circumference of the island is given by the formula ...
C = πd
where d represents the diameter of the circle.
Halfway around is half the circumference, so the distance the penguin swam is ...
1/2C = (1/2)π(20 m) = 10π m

The temperature at noon is 7 less than twice the temperature at 6:00 a.m. At noon it is 61 degrees. The temperature at 6:00 a.m. is t degrees. what is the temperature at 6:00 a.m.?
Answer:
34 degrees
Step-by-step explanation:
The equation that represents this situation is
2t - 7 = 61
to solve, start by adding 7 to both sides
2t = 68
then divide both sides by 2
t = 34

Answer:
D as 32 divided by 8 is 4
Step-by-step explanation:
A quotient is a result obtained by dividing one quantity by another.
Answer:
The second choice is the correct answer. d/8=4
Step-by-step explanation:
if something is a quotient it means it is the solution of a division problem. So we know it cant be the first. the last one doesn't make sense because it says that 8 and a number d equals 4 so it cant be that 8*4=d. that also goes for the third problem because it has to equal 4 and that equals d not 4.
To find this out we see that because it is the quotient of a number and 8 is 4, that means that we have to have a number divided by 8, the only one with that is the second one.

Use similar triangles to solve for the missing lengths below.
If you know how to work this out please help:)
Answer:
x = 14
y = 18
Step-by-step explanation:
By the property of similar triangles,
If two triangles are similar their corresponding sides will be proportional.
[tex]\frac{AB}{EF}= \frac{AC}{GE}[/tex]
[tex]\frac{5}{10}=\frac{7}{x}[/tex]
x = [tex]\frac{70}{5}[/tex]
x = 14
Similarly, [tex]\frac{AB}{EF}= \frac{CB}{GF}[/tex]
[tex]\frac{5}{10}=\frac{9}{y}[/tex]
y = [tex]\frac{90}{5}[/tex]
y = 18

Answer:
5500 ml or 5.5 liters
Step-by-step explanation:
First, we should note that there are 1000 milliliters in 1 liter of liquid.
So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.
To find the total amount, we find the sum of all the milliliters:
1500 + 750 + 2250 + 1000 = 5500 ml
Again, we know that there are 1000 milliliters in 1 liter of liquid, so:
[tex]\frac{5500}{1000}[/tex] = 5.5 liters

The automobile insurance
company receives 18 calls in 6
hours. How many calls do they
received in 11 hours?
Answer:
33
Step-by-step explanation:
An easy way to do this is create a proportion.
[tex]\frac{18}{6} = \frac{x}{11}[/tex]
Keep in mind you could also write this equation as [tex]\frac{6}{18} = \frac{11}{x}[/tex] as long as you are consistent. The number of calls should be in the same place and the hours should also be in the same place (either the numerator or denominator).
Next, just cross multiply.
6x = (18)(11)
6x = 198
x = 33 calls
Answer:
They would get 33 calls!
Step-by-step explanation:
Hope this helps!

You deposit $2700 in an account that pays 3% annual interest compounded weekly. How much money is in the account after 5 years?
Answer:
A = $3136.86
Step-by-step explanation:
Given the following data;
Principal = $2700
Interest rate = 3% = 3/100 = 0.03
Number of times = 52
Time = 5 years
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 2700(1 + \frac{0.03}{52})^{52*5}[/tex]
[tex] A = 2700(1 + 0.0005769)^{260}[/tex]
[tex] A = 2700(1.0005769)^{260}[/tex]
[tex] A = 2700(1.1618)[/tex]
A = $3136.86

(2, 2), (6,3), and (5,5). Find the measure of the longest diagonal.
Answer:
idontknow
Step-by-step explanation:
Answer:
first you need to understand what is a diagonal then if you understand them you can use the opposite coordinates to calculate the diagonals using the distance formula for example [tex] [/tex][tex]d = \sqrt{(x - x) { }^{2} } + \sqrt{(y} - y) {?}^{2} [/tex]then after that you will subtitute the for x of opposite vertices same for y make sure if you get an answer you take a positive square root if i a rootTwo similar squares are in a ratio of 3:5.
