Answer:
50% value change.
Step-by-step explanation:
A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.
Therefore, $15 is a 50% percent change from $10.
Is the 6% already added or am I supposed to add the tax
Step-by-step explanation:
a ) Distance = 7150 km , speed = 780 km / hr So , time taken. ... 42 5 m / sec So , Time taken = Distance Speed = 8 0 . 42 / 5 = 8 × 5 0 . 42 sec = 95 .
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [a, b ] is

Here [ a, b ] = [ 2, 6 ], thus
f(b) = f(6) = -
+ 70 = - 64 + 70 = 6
f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66
average rate of change =
=
= - 15 → A
Hello Alondra,
To solve this problem, you have to write a proportion using the ratios formed by the similar triangles.
Or proportion can be:
x/(x+2) = 10/15
Cross multiply to solve it:
10x + 20 = 15x
20 = 5x
4 = x
The value of x is 4.
I hope this helps,
