What is the volume of the right prism? A.
23 cm3

B.
46 cm3

C.
192.5 cm3

D.
385 cm3
What is the volume of the right prism? A. 23 - 1

Answers

Answer 1
Answer: The answer to this is C.

To figure out the volume of a prism use LWH/2.

Think of it as a 2D triangle when finding the area you times by width and height and then divide by two. In this case the shape is 3D, but it is still the same concept, except that you are also timing it by the length also.

Hope that helps : )
Answer 2
Answer: the anwer is c you have to multiply 11*7*5=385/2=192.5 so hope that helps

Copy and complete the table below to represent the amount of time it would take Meredith to get her friends house if she traveled at different rates

Answers

Answer with explanation:

Formula used here ,

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

It is given that the distance between Meredith and her friends house =2 4 blocks

Then At Speed = 1 block per minute.

\text{Time}=(24)/(1)= 24 minutes.

At Speed = 2 block per minute.

\text{Time}=(24)/(2)= 12 minutes.

At Speed = 3 block per minute.

\text{Time}=(24)/(3)= 8 minutes.

At Speed = 4 block per minute.

\text{Time}=(24)/(4)= 6 minutes.

At Speed = 6 block per minute.

\text{Time}=(24)/(6)= 4 minutes.

At Speed = 8 block per minute.

\text{Time}=(24)/(8)= 3 minutes.

At Speed = 10 block per minute.

\text{Time}=(24)/(10)= 2.4 minutes.

At Speed = 12 block per minute.

\text{Time}=(24)/(12)= 2 minutes.

At Speed = 24 block per minute.

\text{Time}=(24)/(24)= 1 minute.

This problem can be solved by using the formula for

linear motions. The formula relating velocity, distance and time is:

t = d / v

where t is time, d is distance and v is velocity

 

We are given that d = 24 blocks

 

When v = 1 block / minute

t = 24 blocks / (1 block / minute)

t = 24 minutes

 

When v = 2 block / minute

t = 24 blocks / (2 block / minute)

t = 12 minutes

 

Hence we can see that it takes half the time when she is

travelling at 2 blocks per minute.

What's number is 35% of 20

Answers

'is' in mathematics means equal
'of' in mathematics means multiplication

35% can also be written as 35/100

x = (35)/(100) * 20\n\nx = (35)/(10) * 2\n\nx = 3.5 * 2\n\n\boxed{\bf{x = 7}}
7 is 35% of 20

Convert percentage into a decimal: 35%/100 = 0.35
Multiply decimal by 20: 0.35 × 20 = 7 <-- our answer.

I am needing to know the answer to 3/7 of what number is 9?

Answers

In math, "of" almost always means "times".

So your question is:  3/7 times (the number) = 9

Multiply each side of that equation by  7 :   3 times (the number) = 63

Divide each side by 3 :              The number = 21
The best thing to do is to find out what 1/7 is.
9/7= 1.28
1.28x3= 3.84
Therefore 3/7 of 9 is 3.84
Hope this helps :)

Can someone please help me with number 25

Answers

Hi there!

{x}^(2) + 10x + 24 = (x + a)(x + b)
To find the values of a and b we must find two integers with a sum of 10. The numbers multiplied must be 24. We can now conclude we're looking for the numbers 4 and 6.

{x}^(2) + 10x + 24 = (x + 4)(x +6 )
b can therefore either be 4 or 6. The answers are 4 and 6.
