Answer:
1. $1,122
2. $485.25
3. $440
4. $2,047.25
Step-by-step explanation:
1. 22 feet * 17 feet = 374 square feet * $3 per square foot = $1,122
2. 17 feet * 10 feet * 4 walls = 680 square feet. 680 feet - (7ft*3ft for the door) - (2*2ft*3ft for the windows) = 647 square feet * $0.75 per square foot = $485.25
3. 374 square feet/ $88 per gallon = 4.25 gallons which rounds up to 5 gallons, and 5 gallons at a cost of $88 per gallon = $440
4. $1,122 + $485.25 + $440 = $2,047.25
Answer: 7,833
Step-by-step explanation:
Answer:
1) 2.6 ft³
Step-by-step explanation:
for the first one, multiply height times width times depth divided by two, since it is a triangle. Area of a triangle is always height times width divided by two.
So
(1.3 × 1 × 4)/2 = 2.6 ft³
The second one you can see as 6 of those triangle bars glued together, can you calculate the volume then?
<span>1. mileage Per gallon of Mrs. Mouths car = no. of miles / no. of gallons
= 360 / 25 = 14.4 miles per gallon
</span>2. mileage Per gallon of Mr. brains car = no. of miles / no. of gallons
= 480 / 32 = 15.0 miles per gallon
3. Mr. brains car has better mileage per gallon than Mrs. Mouths car.
