Answer: 34
Step-by-step explanation:
Answer:
11) Here given Function,

And, 
For f(x) = g(x)






When we solve this equation,
We found,
x = 12.5227 ≈ 12.53
Thus, the required solution is, x = 12.53
12) Here the height of rocket A in x second,

And, The height gain by the rocket B in x seconds,

If at x seconds both A and B gain the same height,
That is, f(x) = g(x)
⇒ 
⇒
⇒ 
⇒ 
⇒ x = 1.125 ≈ 1.13
Thus, the required solution is x = 1.13 seconds (approx)
Answer:
15 quarters, 10 nickels
Step-by-step explanation:


multiply the first equation by -0.25 and add the second equation to it

________________

has 10 nickels
has 15 quarters
10(.05) +15(0.25) = 0.5 + 3.75 = 4.25

a.For this part just draw a triangle with sides 4,8 and 8 inches respectively.
The sides having 8 inches should make equal angle with the base side.
b.One angle is 20
The other two angles be x and y
but x=y because its an isosceles triangle
x+y+20=180
2x=160
x=80
Hope this helps.
The square root of 64 is 8 and the square root of 100 is 10.... so,
square root of 64/100 = 8/10
8/10 reduces to 4/5
