Answer:
Pual needs 3 gallons
Step-by-step explanation:
∵ The dimensions of the four walls are:
25 × 8 , 30 × 8 , 25 × 8 , 30 × 8
∴ The area of painting = 2(25 × 8) + 2(30 × 8)
= 400 + 480 = 880 square feet
∵ each gallon paint 400 square feet
∴ The number of gallons = 880/400 = 2.2, so he needs 3 gallons
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
Answer:
and growth rate factor is 0.075
Step-by-step explanation:
The function that models the population of iguanas in a reptile garden is given by , where x is the number of years.
Since,
i.e. .
Therefore, the monthly growth rate function becomes,
i.e. .
i.e. .
Hence, the monthly growth rate is i.e. .
Also, the growth factor is given by = 0.075.
Thus, the growth factor to nearest thousandth place is 0.075.
Answer:
2 millimeters.
Step-by-step explanation:
1 millimeter : 6 meters
x millimeters : 12 meters
x = (12÷6) × 1
x = 2×1
x = 2 millimeters
Answer: x =
Step-by-step explanation: Multiply -36 and 163/9 to get -652. Add 652 to both sides then add 130 and 652 to get 782. Divide both sides by -12 then reduce the fraction 782/-12 to lowest terms by extracting and canceling out 2. The system is now solved.
