Answer:
863.141 = (8 x 100) + (6 x 10) + (3 x 1) + (1/10) + (4/100) + (1/1000).
Step-by-step explanation:
Answer:
$16.67
Step-by-step explanation:
-Let Ben's expenditure be X,
#Ava's expenditure being three times Ben will be 3X, and half as much as Cora(2X)
-Given that the total expenditure was 50, Cora's portion is calculated as :
Hence, Cora's expenditure is $16.67
<u>Estimate
5.</u> 49.2 this is actually 20% but its close enough to estimate <u>
6.</u> 120 this is closer to 150%<u>
7.</u> 226.8 this is 70%
<u>
8.</u> 36 this is closer to 55%
<u>
9.</u> It would be closer to fifteen minutes because 25% = 1/4 and 15/45 = 25% and 45 minutes is close to 50 min
<u>write an equation
</u><u>10.</u> 14% = .14 so .14×64 = 8.96<u>
</u><u>
11.</u> x = .36 × 194 x = 69.84<u>
12.</u> .82x = 73.8 divide each side by .82 x = 90<u>
13.</u> 75 = 50x divide each side by 50 x = 1.50 or 150%
