Answer:
<em>The speeds are 877 km/h and 947 km/h.</em>
Step-by-step explanation:
The slower plane travels at x km/h. The faster plane travels at (x + 70) km/h. The speed of separation is the sum of the speeds, (2x + 70) km/h.
They are 5472 km after 3 hours of travel.
speed = distance/time
2x + 70 = 5472/3
2x + 70 = 1824
2x = 1754
x = 877
The slower plane travels at 877 km/h.
x + 70 = 877 + 70 = 947
The faster plane travels at 947 km/h.
Answer:
SA. = 62.8 +87.92= 150.72
Step-by-step explanation:
surface area of cone without base = pi*r*s = 3.14 * 2* 10 = 62.8
Surface area of cylinder without base = 2*pi*r*h + pi*r*r
= 2* 3.14 * 2 * 6 + 3.14*2*2
= 75.36 + 12.56 = 87.92
SA. = 62.8 +87.92= 150.72

Answer:
6.4 ounces
Step-by-step explanation:
10% of 64 ounces is ...
0.10 × 64 = 6.4 . . . . ounces
Cam needs to drink 6.4 ounces to reach the recommended amount.
Increasing the value of a would change the slope of the function specifically it would increase as well. Therefore, the line would be steeper than the original. The term ab represents the slope of the function and changing either one would result to the change of the steepness of the line.
