Answer: 11.30
Step-by-step explanation:
We wouod solve this using the formula:
= πr²h
= 3.14 × 3² × 10
= 3.14 × 9 × 10
= 282.6cm³
Since the cost is 0.04 cents per cm³, the total cost will then be:
= 282.6 × 0.04 cents
= 11.30 cents

Mr.Sawyer drove his car from his home to New York at the rate of 45mph and returned over the same road at the rate of 40mph. If his time returning exceeded his time going and his time returning?
Complete question :
Mr. Sawyer drove his car from his home to New York at the rate of 45 mph and returned over the same road at the rate of 40 mph. If his time returning exceeded his time going by 30 min, find his time going and his time returning.
Answer:
T1 = 4
T2 = 4.5
Step-by-step explanation:
Difference in time = 0.5 hour
Time = distance / speed
Let distance = d
Time, T1 = d / 45
Time, T2 = d / 40
d/40 - d /45 = 1/2
(45d - 40d) / 100 = 2
45d - 40d = 900
5d = 900
d = 180
T1 = 180 /45 = 4 hours
T2 = 180 / 40 = 4.5 hours
A boat traveled 150 miles downstream (with the current) and back (against the current). The trip downstream took 10 hours. The trip back took 30 hours. What is the speed of the boat (b) in still water? What is the speed of the current (c)?
Answer:
b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
Freddy’s savings account went from $520 to $321 after he purchased a new bike. What was the percent decrease?
Step-by-step explanation:
The bike cost $199 to get $199 you do a number line then label 520 then at the end label 321 so then you do -20 then -100 then -50 then -20 then -9. so now you add them up 20+100+50+20+9 which equals =199
so bike cost $199
then 520%×199= 1034.8
or 520%×321=1669.2
so the percentage is 1669.2 or 1034.8 probably 1669.2 but they bot count.
How long does it need to keep $600 in an account that pays 2.75% annual simple interest to earn $264?
Answer:
16 years
Step-by-step explanation:
Principal amount (P) = $600
Rate of interest (R) = 2.75%
Simple interest (S.I.) = $264
Let t denotes time period.
[tex]S.I.=\frac{PRT}{100}[/tex]
[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]
[tex]t=16[/tex] years.
Therefore,
interest of $264 will be earned in 16 years.

how could you represent the following scenarios of the graph ? Silvia has $5.50 in her piggy bank and earns $2
per chore she does at her house.
Answer:
We know that Silvia has $5.50 in her piggy bank, and she earns $2 per chore she does at her house.
So if she does x chores at her house, she will have:
y = f(x) = $2*x + $5.50
where y = her savings.
This is a linear relationship, to graph this, we need to evaluate the function in two different values of x so we can get two ordered pairs.
Then we graph the ordered pairs in the coordinate axis, and then we draw a line that passes through both points.
We can use the points given by x = 0.
y = f(0) = $2*0 + $5.50 = $5.50
Then we have the point (0, $5.50)
and if we use x = 1 we get:
y = f(1) = $2*1 + $5.50 = $7.50
Then we have the point (1, $7.50)
Now we just need to graph the points (0, $5.50) and (1, $7.50), and draw a line that passes through them.
The graph is shown below.

While in New York City, is it a better deal for a group of friends to take a taxi or the subway to get from the Empire State Building to the Metropolitan Museum of Art? Explain your reasoning.
Here is some information about New York City and its transportation system.
Information about NYC taxi cabs:
As of 2020, taxi cabs charge an initial fee of $2.50. Then there is an additional charge of $0.50 per 1/5 mile if the car is traveling about 12 miles per hour. In slower or stopped traffic, the additional fee is $0.50 per minute.
Information about the NYC subways:
As of 2020, a single subway ride is 2.75. However, multiple day passes can be purchased at a discount rate.
Information about the NYC tourist attractions:
The distance between the Empire State Building and the Metropolitan Museum of Art varies between 2.5 miles to 3.2 miles depending on your route.
Answer:
It would definitely be cheaper by Subway..
Step-by-step explanation:
Subway is 2.75 per person and taxi (given all variables) could be close to $20...however, the Subway takes much longer but is still the best bet. Especially if traffic is an issue
Line 6 subway•24m

At a recent breakfast, four friends paid for their own drinks and shared the cost of a bag of donuts. Joe's drink was $1.75. He paid a total of $3.20 for breakfast. How much did the bag of donuts cost?
Answer:
$5.80
Step-by-step explanation:
To answer, we must first subtract the toal cost Joe paid by the amount he paid for his drink, because ha paid for his drink separately. so:
3.20 - 1.75 = 1.45
And because there were a total of 4 friends, we mulitply the answer by 4:
1.45 * 4 = 5.8
So, the bag of donuts costed $5.80
Hope this helps :)

When a ball is dropped, the function () = 4(0.6)x models the ball’s height in feet after each bounce, where x is the bounce number. To the nearest hundredth, what is the height after the third bounce?
Answer:
7.2 feet
Step-by-step explanation:
plug in x = 3 since we are looking for the height after the 3rd bounce
4(0.6)(3)
4(1.8)
7.2
The height after the third bounce is 0.86 feet.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 4 x [tex]0.6^x[/tex] models the ball’s height in feet after each bounce.
Where x is the bounce number.
Now,
Substituting x = 3,
f(x) = 4 x [tex]0.6^x[/tex]
f(x) = 4 x [tex]0.6^3[/tex]
f(x) = 4 x 0.6 x 0.6 x 0.6
f(x) = 0.864
f(x) = 0.86
The height after the third bounce is 0.86 feet.
