The value of the first 2 is 20 the value of the second 2 is 200 as in hundreds and the firs being tens
Im betting it’s gonnna be $5,400 because when finding the area of the floor of the pool you can find the cost of that then multiply that by 5 for the entire pool
4.3 because 5 rounds up, and 25 rounds to 30.
Answer:
36 mph
Step-by-step explanation:
The appropriate relations are ...
time = distance/speed
speed = distance/time
Suppose the race has a total length of 360 miles. Then half the race is 180 miles.
The cyclist's time on the first half is (180 mi)/(30 mi/h) = 6 h.
The cyclist's time on the second half is (180 mi)/(45 mi/h) = 4 h.
The total time is 10 h for the total distance of 360 mi, so the average speed is ...
(360 mi)/(10 h) = 36 mi/h
_____
The length of the race doesn't matter. The above numbers make the math convenient. The average is computed from ...
1/((1/2)/30 + (1/2)/45) = 2/(1/30 +1/45) = 2·30·45/(30+45) = 36
This is the <em>harmonic mean</em> of the numbers 30 and 45.
<span>-2.9x + 5.4y = 140.94
answer is </span><span>y-intercept is 26.1
cause when </span><span>y-intercept x = 0
</span>-2.9(0)+ 5.4y = 140.94
<span>5.4 y = 140.94
y = 140.94 / 5.4
y = 26.1
