Answer:
<h3>55 secs</h3>
Step-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds
Answer: 87.75
Step-by-step explanation:
Multiply 12.25 times 3 because the student bought 3 shirts
Then multiply 25.50 times 2 because the student bought two pairs of pants
Then add up both your multiplication together and you will get 87.75
Per 1 yard the cost would be $0.38. Not sure what unit you need it in, but thats the answer in yards.
8x - 2y = 48, y =4
8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x = 56
x = 56/8 = 7
x = 7
