Step-by-step explanation:

First find the area of Lot X

67 • 70 = 4,690

Subtract the are of Lot X from the total area

8,375 - 4,690 = 3,685

3,685 is the area of Lot Y

Now divide 3,685 by the length of Lot Y : 67

3,685 ÷ 67 = 55

The width of Lot Y is 55 ft.

is my awnser is 73.97$ what's the 6.25% tax I have to convert 6.25 to a decimal​ CASLAN

Answers

Answer:

Not sure I understand your question.

If the tax rate is 6.25% and you need the tax from $73.97, tax is:

= 6.25% * 73.97

= $4.62

Converting 6.25% to decimal.

First understand that when a percent sign(%) is next to a number it means that the number is a fraction and its denominator is 100.

6.25% = 6.25/100

To convert to decimal, divide the numerator by the denominator:

= 6.25 ÷ 100

= 0.0625

Heather is building a ladder for her tree house. She will need 13 feet of lumber for each stilt and 2 feet of lumber for each rung on the ladder. How many feet of lumber does she need for a ladder with 2 stilts and 12 rungs?
29 feet because 2 + 13 + 12 + 2 = 29
50 feet because 2 (13) + 12 (2) = 50
160 feet because 13 (12) + 2 (2) = 160
210 feet because (2 + 13) (12 + 2) = 210

Answers

Answer:

B. 50

Step-by-step explanation:

For two stilts, you'd multiply 13 by two.

2(13) = 26

For twelve rungs you multiply 2 by 12.

12(2) = 24

Then you add the two numbers together to see how much would she needs.

24 + 26 = 50

This gives you the answer, which is equivalent to B.
