The hole for a support needs to be 5 feet deep. It is currently 2 feet 5 inches deep. How much deeper must the hole​ be?
Factor 12 inches/ 1 foot

Answers

Answer 1

Answer: 2 feet, 7 inches

Step-by-step explanation:

2 feet can be converted to 24 inches

5 feet can be converted to 60 inches

60-29=31

31/12=2 7/12

2 feet, 7 inches

Answer 2
What you need to calculate is how many feet deeper the hole needs to be.
Let’s try to do this a different way. 5 feet is= 60 inches.
2 feet 5 inches=29 inches
60-29=31
How many feet can fit into 31 inches?
2 feet
With 7 inches left over.
2 feet 7 inches.

Answer:

228

Step-by-step explanation:

[Formulas Below]

Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.

Area of Triangle = (Length * Height)/2

Area of Rectangle = Length * Width

228! The answer is correct :)

If the lowest temperature in Whitesboro for the week was -1°F and the highest temperature was 20°F, what was the total change in temperature?

Will give brainliest!!

Answers

Answer: The total change is 21.

Since you want to find the change from the lowest to highest, make it into a subtraction problem. First of all, take the smallest number in front of the largest.

20 -1

Next, add a minus sign in between, your equation should look like this:

20 - (-1) = x

Then, you cancel out the negative signs. After that you solve it

20 - (-1) -> 20 + 1.

Lastly, you add them together.

20 + 1 = 21.

In conclusion, the answer is 21.

Answer:

21°F

Step-by-step explanation:

It went from -1 to 20

[-1]= 1

1+20

21

it went up or down 21°F

Adrian works full time at the office supply store. He earns $525 each week. He wants to raise his income to at least $650 each week, so he takes on a part-time job which pays $12 per hour. How many hours would Adrian need to work each week at his part-time job in order to raise his total weekly income to at least $650?

Answers

Answer:The total number of hours worked in the week is 46. The hourly pay would be 40(14) + 6(21) = $686 per week. The annual earnings are 52(686) = $35,672. The salary pay is more than the hourly pay based on the typical hours worked each week given in the table. Therefore, the employee would probably want to choose the salaried pay.

Answers

Answer:

13 inches

Explanation:

First, you must remember that the perimeter of a shape is what you get when you add up all of the side lengths. With this information, and the fact that the problem has given us a perimeter of 30 inches and expressions for each side, it should be easy to form an equation of: 30=2x+3+4x-8+x. Now we just do the algebra...

1) Combine like terms: 30=2x+3+4x-8+x

30=7x-5

2) Add 5 to both sides: 35=7x

3) Divide both sides by 7: 5=x

Now you have a value for x (x=5). We can then plug in 5 for every instance of x. Our three side lengths are now:

5, 2(5)+3 ad 4(5)-8. If we simplify, our three side lengths become 5, 13 and 12. The question asks us for the longest side length, and out of the three this is 13. Therefore, our answer is 13 inches.

Hope this helps!

(Please Help) You have a board of wood that measures 9 3/4 feet. You cut a piece off the board measuring 2 15/16 feet and then another piece measuring 4 3/8 feet. You now need a piece that is 2 1/2 feet long. You say your remaining board of wood is long enough. Is this reasonable?

Answers

Answer:

no

Step-by-step explanation:

9 3/4 -(2 15/16+4 3/8)

give a common denomenator for all of the fractions.

=9 12/16 - (2 15/16 + 4 6/16)

=9 12/16 - 7 5/16

=2 7/16
