Answers

Answer:

The answer is C. But I got 350.82

Step-by-step explanation:

The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48

The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82

Then we add up all the areas 302.82+48 to get 350.82

Because this answer is slightly different I would assume it is C.

So I got this question wrong and am wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain

Answers

Answer:

you have four walls. two of them 12*8 and other two is 10*8 ( we used 8 in both because its the height of the room) . so it goes( 2*12*8)+(2*10*8) and it goes 352

Step-by-step explanation:

lets say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper .

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total you need 160+192= 352 square feet wallpaper

Answers

Answer:

a) 7/12

b) 1/6

Step-by-step explanation:

(1)

Number greater than 5 include;

6, 7, 8, 9,10, 11, & 12

= 7

Probability of event = number of outcome ( total number of possible events )

= 7/ 12

(2)

Total number of possible events =  180 * 12

= 2160

Number of outcomes for;

Rolling a 3 = 1 * 120 / 2160 = 120/2160

Rolling a 9 = 1 * 120/2160 = 120/2160

Rolling a 11 = 1 * 120/2160 = 120/2160

120/2160 * 3

360/2160

Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answers

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

What is simplification?

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Based on this data, what is a reasonable estimate of the probability that the next voter does not agree to the new amendment?

Answers

Answer:

The probability that the next voter does not agree to the new amendment is 0.2584 or 316/1223

Step-by-step explanation:

For this we have to subtract the number of voters who accepted the new amendment from the total number of voters

1223 - 907 = 316

To calculate the probability that someone will not vote in favor of the amendment we simply have to divide the number of negative votes by the number of total votes

316 / 1223 = 0.2584

The probability that the next voter does not agree to the new amendment is 0.2584

Answers

Answer:

She can make 97 ribbons from her roll

Answer:

Robin can make 49.28 ribbons. Or if you wish to round, 49 ribbons.

Step-by-step explanation:

Her roll of ribbon is 30.8 ft long.

She needs 0.625 ft for each ribbon.

Divide 30.8 by 0.625

30.8 ÷ 0.625 = 49.28
