Answer:

A = 324m²

Step-by-step explanation:

Formula for finding the surface area of a rectangular prism:

2(wl + hl + hw)

First, let's find out which one of the measurements is the height, length, or width.

6m = length

16m = width

3m = height

Next, we calculate the surface area. We have to do the formula one by one too.

2(wl + hl + hw)

2(16x6 + 3x6 + 3x16)

16 x 6 = 96

3 x 6 = 18

3 x 16 = 48

Now, we add those together.

96 + 18 + 48 = 162

Lastly, multiply by 2.

162 x 2 = 324

Therefore, A = 324m²

The answer would be 4 5/8 because if you add all the numbers together that would result with 37. Then you want to find a number inside 37 that can be divided by 8, which would be 32. You will get 4 and the remaining 5 from the fraction stays as 5/8 now you combine the 4 and 5/8.

Which product is negative? will mark brainliest

Answers

The third one. I’ve shown my work below. The first two are positive and the last one is 0, which is neither positive nor negative

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.
So the answer is the third one

A video store charges the same fee each day a video is returned late. Craig returned a video 4 days late and paid a $3 fee. Write a proportional equation that can be used to find the late fee for a video that is returned 7 days late. What is the fee for a video that is returned 7 days late? Explain how you know.

Answers

Answer:

$5.25 if returned 7 days late

Step-by-step explanation:

So we know that 4 days late is 3 dollars

We can find the unit rate

3/4 is 0.75

So 75 cents for every late day

Now we just multiply that by 7

0.75*7=5.25

so 7 days, 5.25

**porportional relationship equation**

$\frac{3dollars}{4 days}$=$\frac{X}{7 days}$

Now cross multiply

21=4x

x=5.25

Same results

$5.25 if returned 7 days late

Convert to find the equivalent rate.

Which numbers are irrational? Mark all that apply.

Answers

Answer:

E and F

Step-by-step explanation:

An irrational number is one which cannot be expressed in the form p/q where p and q are both integers.

A number with a repeating decimal is a rational. So 0.5737373.. is not irrational

π is a non-terminating and non-repeating decimal. This cannot be written as a fraction of two whole numbers. So π is irrational

Square roots of prime numbers are irrational. Since 11 is prime, √11 is irrational

Responses
A 3939
B 1616
C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16
