Answer:
h ≤ 8
Step-by-step explanation:
Hans charges $7 per hour and pays $5 in equipment fees.
$5 is fixed in this case. Let the possible number of hours be h.
According to question,
Atleast means less than equal to. So,
7h-5≤51
Add 5 to both sides.
7h+5-5 ≤ 51+5
7h ≤ 56
h ≤ 8
So, the number of hours be less than equal to 8.
We use the given data above to calculate the volume of gasoline that is being burned per minute by commercial airplanes.
Amount burned of 1 commercial airplane = <span>3.9 × 10³ ml of gasoline per second
Number of airplanes = </span><span>5.1 × 10³ airplanes
We calculate as follows:
</span> 3.9 × 10³ ml of gasoline per second / 1 airplane (5.1 × 10³ airplanes)(60 second / 1 min ) = <span>1.2 x 10^9 mL / min</span>

Answer:
110 cm
Step-by-step explanation:
So if we know the diameter, which is 35 cm, we can use the formula π*d. So we would take the diameter and put it in the place of d. So it would be pie times 35. Which would result in us getting 109.96. And this rounded to the nearest tenth would be 110. So The circumference would be 110 cm.
