Answer:

38 packages of erasers

Step-by-step explanation:

Divide 149 by 4 to determine the amount of packs

this is gives you 37.25, but you can't have a 0.25 of a package

therefore you would need 38 to compensate that 0.25 of a package

Alice purchased paint in a bucket with a radius of 9 in. and a height of 9.5 in. The paint cost $0.09 per in3.
coldgirl [10]
\pir^2 = cross-sectional area of paintbucket.
3.14 (Your approximate value of pi) * 9^2 = 254.34
254.34 * 9.5 = total volume of bucket.
2,416.23 in^3.

0.09$ * 2416.23 = cost
The cost would be $217.46 (To the nearest cent)

irakobra [83]

Answer:

(a)6.82mph

(b)22 ft/sec

Step-by-step explanation:

Eric's Speed = 10 ft/sec

The Ferry's Speed = 15 miles per hour

<u>Conversion Unit</u>

  • 1 mile = 5280 feet
  • 1 hour = 3600 seconds

<u>Guide</u>

  • When converting from a smaller unit to a larger unit we divide
  • When converting from a larger unit to a smaller unit we multiply

(a)To convert Eric's Speed 10 ft/sec to miles per hour

\dfrac{10 \:ft}{seconds} =\dfrac{10 \div 5280 \:miles}{1 \div 3600\: hour} \\=6.82 miles \:per\: hour

(b)To convert the Ferry's Speed 15 mph to ft/sec

\dfrac{15 \:miles}{hour} =\dfrac{15 X 5280 \:foot}{1 X 3600\:seconds} \\=22 foot \:per\: seconds
