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

This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.

Answers

Answer:

There are 10 counters in the bag and you want the 4

As their is only one for the probability is

1/10

There are now 9 counters left in the bag.

You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is

4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90

Step-by-step explanation:

The probability of getting a multiple of 3 both times is 2/30.

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

We are randomly picking two numbers from 1-10.

Multiple of 3 between 1 and 10 are 3, 6, 9.

To find the probability:

Here, we are considering the that the numbers are chosen without replacement.

The probability of getting a multiple of 3 both times,

= 3/10 x 2/9

= 6/90

= 2/30

Therefore, the probability is 2/30.

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

= 1/6

Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10

Answers

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Step-by-step explanation:

5x - 3x = 10

2x = 10  Divide by 2

x=5

2(2x - 1) = 46   Distribute the 2

4x - 2 = 46  Add 2

4x = 48  Subtract by 4

x = 12

6x - 15 = 75  Add 15

6x = 90  Divide by 6

x=15

x + x - 10 =26  Add the x's together and the 10

2x = 36  Divide by 2

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.

Robin made ribbons for school spirit day. Robin has 15 friends who
want ribbons. Her roll of ribbon was 30.8 feet long. For each individual
ribbon she needed 0.625 ft. How many ribbons could she make from
her roll?

Answers

Answer:

She can make 97 ribbons from her roll

Step-by-step explanation:

30.8 divided by 0.625 is 97.28, but the friends would like whole rolls, so I got 97

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

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
