What is 30% of a $24.50 item

Answers

Overall Answer:

$7.35

Complete answer:

30% of $24.50 is $7.35

Step-by-step explanation:

30% of a $24.50 item

Here are two ways to solve:

Option 1:

30% = 30/100 = 3/10 = 0.3

Multiply $24.50 by 0.3

24.50 * 0.3 = 7.35

Option 2:

30% = 30/100

Create an equation using fractions using the variable x

30/100 = x/24.50

Cross multiply (numerator * denominator / numerator * denominator)

30(24.50) = x(100)

735 = 100x

x = 7.35

Hope this helps :) Feel free to let me know if you need me to clarify any part of my answer.

What is 13.8924439894 rounded to the nearest tenth

Answers

1st decimal place=tenth
2nd=hundreth

to round, you look at the place after it
so 13.8924439894 to tenth
look untill hundreth
13.89
if hundreth>5, round tenth up
if hundreth place<5 leave tenth as is

13.89
9>5
round up
8+1=9
13.9 is to theh tenth

the answer is 13. 90 if you round it to the nearest tenth. the nearest tenth is the 9 the first nine.( if the number is 0-5 then it will become a 0 but if the number is 5-9 you would add one to the number in front of it) since the number is 9 then the 8 would become a 9 so your answer would be 13.90

A sandbox is 1 1/3 feet tall, 1 5/8 feet wide,and4 1/2 feet long. How many cubic feet of sand will it hold

Answers

volume=legnth times width times height
convert all to iimporper fractions first for ease
1 and 1/3=1+1/3=3/3+1/3=4/3

1 and 5/8=1+5/8=8/8+5/8=13/8

4 and 1/2=4+1/2=8/2+1/2=9/2

multiply them
volume=(4/3) times (13/8) times (9/2)
volume=(4 times 13 times 9)/(3 times 8 times 2)
volume=468/48
volume=39/4
volume=9 and 3/4 cubic feet
Volume (sandbox)= long x wide  x tall

long=4 1/2 ft=(4+1/2) ft=(8+1)/2 ft=9/2 ft
wide=1  5/8 ft=(1+5/8)ft= (8+5)/8 ft=13/8 ft
tall=1 1/2 ft= (1+1/2)ft=(2+1)/2 ft=3/2 ft

Volume=9/2 ft * 13/8 ft * 3/2 ft=(9*13*3) / (2*8*2) ft=351/32 ft³

351/32 ft³=(10*32 + 31)/32 ft³=10 + 31/32 ft³=10  31/32 ft³.

Answer:351/32 ft³   or    10  31/32 ft³
