Answer:
150%
Step-by-step explanation:
15 / 10 =
1.5 =
150%
a=20(5)+30
20*5=100
100+30=130
Altitude: 130 yards.
The balloon's altitude increases by 5 yards each minute. So, after 20 minutes, the balloon has ascended 100 additional yards. If it was initially 30 yards above the ground, it is now at an altitude of 130 yards.
Based on the provided information, the altitude of the balloon changes at a rate of 5 yards per minute. At the beginning, the balloon is 30 yards above the ground. This initial altitude is increased by the amount of change happening every minute. Therefore, after 20 minutes of continuous upward movement, the change in altitude is 20 minutes * 5 yards/minute = 100 yards. Thus, the final altitude of the balloon becomes the sum of its initial altitude and the change, which is 30 yards + 100 yards = 130 yards.

Which of the following statement about (c + 2)(15c – 14) is true?
A. The expression is equivalent, and it is completely factored.
B. The expression is equivalent, but it is not completely factored.
C. The expression is not equivalent, but it is completely factored.
D.The expression is not equivalent, and it is not completely factored.
Answer : C. The expression is not equivalent, but it is completely factored.
can be factored
15 * -28 = -420
21 and -20 are the factors whose sum is +1 and product is -420
This is not equivalent to (c + 2)(15c - 14)
But (c + 2)(15c – 14) is completely factored
So , The expression is not equivalent, but it is completely factored.
Answer:
17400
Step-by-step explanation: i might get this wrong but just do 1.74*10^4 and it should equal 17400
