Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer:

6/12 (50%)

Step-by-step explanation:

If you roll greater than 3 you have a 3/6 chance of it, if you then roll a number less than 4 you have another 3/6 chance of it, therefore it should be 50% or 6/12

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer:1 and 2 is a function. But the third one isn't. explanation: When there is more than one point on a vertical line that is not a function.

Based on the surface area and cost of the boxes, the company saves $11.50 by choosing to make 50 Box 2 instead of 50 Box 1.

To solve this problem, we need to calculate the surface area of each box to determine how much material is needed to make 50 of each box.

The surface area of Box 1 is:

SA1 = 2lw + 2lh + 2wh

SA1 = 2(206) + 2(204) + 2(6*4)

SA1 = 240 + 160 + 48

SA1 = 448 square inches

To convert to square feet, we divide by 144 (since there are 144 square inches in a square foot):

SA1 = 448/144

SA1 = 3.11 square feet

The cost of material for one Box 1 is:

C1 = 1.25 * SA1

C1 = 1.25 * 3.11

C1 = $3.89

The surface area of Box 2 is:

SA2 = 2lw + 2lh + 2wh

SA2 = 2(154) + 2(158) + 2(4*8)

SA2 = 120 + 240 + 64

SA2 = 424 square inches

Converting to square feet:

SA2 = 424/144

SA2 = 2.94 square feet

The cost of material for one Box 2 is:

C2 = 1.25 * SA2

C2 = 1.25 * 2.94

C2 = $3.67

To find the cost savings of making 50 Box 2 instead of 50 Box 1, we calculate the difference in cost:

Savings = (50 * C1) - (50 * C2)

Savings = (50 * 3.89) - (50 * 3.67)

Savings = $11.50

Step-by-step explanation

So i was thinking because each student gets 5 ounces and and there is 24 students. Which means first you have to:

24x5= 120

You know that there are 120 ounces in total but you have to find how many  cups the teacher has. So 120 ounces equals 15 cups im pretty sure.

Answer: 15 cups

Step-by-step explanation: ok this question sounds like it's going to be weird and complicated but it's not this question gave you information you do not need to trip you up ignore that the cornstarch and water don't matter what the question wants is cups of slime 5oz per student 24 students 5X24=120oz     120oz=15 cups

The model shows that there are 9 pieces that are each 2/3 feet long.

A number line is a visual representation of numbers on a straight line. This line is used to compare numbers that are placed at equal intervals on an infinite line that extends on both sides, horizontally or vertically.

In the given figure, whole is divided into two equal parts and numbers are marked for three divisions.

So, the fraction is 2/3.

Therefore, the model shows that there are 9 pieces that are each 2/3 feet long.

Answer:

The art teacher is incorrect.

Step-by-step explanation:

Coming Up with Compatible Estimate Numbers:

The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.

Explaining the Operations:

The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.

Performing the Operations:

Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20

Final Conclusion

For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.

****ANOTHER POSSIBLE SOLUTION****

You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

Explanation:

This is unable to be evaluated due to the function not being stated. X has to be a number for us to be able to solve the equation and for It to be evaluated. 3x to the second power is gonna stay that since there isn't another power integer on 5x and 6 is staying like that since there is nothing for it to be added or subtracted to.
