C. 13 yd 2 ft 6 in × 15
GrogVix [38]

Answer:

7,470

Step-by-step explanation:

<u>Step 1: Convert all into inches</u>

1 feet = 12 inches

2 feet = x inches

<em>Cross multiply</em>

x = 24 inches

1 yard = 36 inches

13 yard = x inches

<em>Cross multiply</em>

x = 468 inches

<u>Step 2: Add all inches together</u>

24 + 468 + 6 = 498 inches

<u>Step 3: Multiply by 15</u>

498 x 15 = 7,470

Therefore, the answer is 7,470.

If the numbers below were ordered from least to greatest, which number could you use to replace the blank? 0.20,2/5 □ , 3/4,8/10
faust18 [17]
1/2 would work for the blank space

because as shown in the image you could relate it to a whole for each one and put it to 100 to figure out what the blank could be

the 0.20 can be converted to 1/5 so that way you can put everything into the 100 group
