HhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhGiven:
trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long 
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches

130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
P = 2(277)
P = 554 inches

Genevieve forgot the last two digits of her four digit locker code the digit she has right now are 21 if the number is divisible by 5 x 6 in by seven what is Genevieve's locker code

If a number is divisible by 5, 6, and 7, 

it's divisible by 5 x 6 x 7 = 210, the least 

common multiple of the numbers. So her number 

is a multiple of 210. The only 4-digit multiple 

is 210 that starts 210 _ is 2100, so that's her number.

Option (A) is correct .

Step-by-step explanation:

As given the statement in the question be as follow.

Shoes salesman sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each.

Thus

Total cost of the pair of shoes = 3 × 70 + 2 × 80

                                                  = 210 + 160

                                                  = $ 370

As given

shoe salesman earns a commission of 30% of all shoe sales made.

30% is written is decimal form

= \frac{30}{100}

= 0.30

Commission earns = 0.30 × Total cost of the pair of shoes .

                               = 0.30 × 370

                               = $ 111

Therefore $111 is earn by shoe salesman as commission .

Anyone know the answer to number 75? I have more questions coming!

Convert 15% to a decimal. When converting percents to decimals, move decimal 2 digits to the left: .15

Find 15% of 1000 gallons: .15 x 1000 gallons = 150 gallons

So the new machine uses 150 gallons less:
Old Machine gallons - 15% of Old Machine gallons = New machine gallons
1000 gallons -150 gallons = 850 gallons

Mark says that to divide 58 by 0.65, you only need to multiply both numbers by ten because that will give you a whole number. Jan says you need to multiply both numbers by 100. Who is correct and why?

Jan is correct because 0.65 times 10 is 6.5, which is still a decimal. 0.65 times 100 is 65, which is a whole number. Then the equation would be 5800 times 65.

Nancy wrote the greatest number that can be made using each of these digits exactly once. 5,3,4,9,8,1. Part A what was Nancy's number? how do you know this is the greatest possible number for this digits?.Part B What is the least number that can be made using each digit exactly once? explain why the value of the 4 is greater than the value of the 5

Answer:

Part A: 985,431

Part B: 134,589

Step-by-step explanation:

In order to solve part A, you just have to take the greatest digit and place it in the far left place of the number, and continue to the next greatest digit, placing it to the right of the last number, this will create a decreasing ladder of digits among the decreasing values of the number, this way Thousands-hundreds-tens-, so you will have the greatest number possible in the highest valued place possible.

To calculate the lowest number possible you just have to do the process for the greatest but instead of taking the highest digit possible, you use the lowest one, this way you will have the lowest number in the highest value position.

The value of 4 is greater than the value of 5 because the 4 represents in the number the thousands, and the 5 in the number represents the hundreds.
