Answer:
8%
Step-by-step explanation:
percent increase = [ (difference between initial value and final value) ÷ initial value] x 100
⇒ percent increase = [ (270 - 250) ÷ 250] x 100 = 8%
Answer:
$165.62
Step-by-step explanation:
284.28-40-48.39-30.27=165.62
Answer:
Third option is correct: 1 / (t+4)^2
Step-by-step explanation:
This equation can be written as the following:
(t+3)/(t+4)*(1/t^2+7t+12)
We know this because of the division of fractions. For example:
(1/y)/(1/x) = (1/y)*(x/1)
Now that we know this, we can advance.
Now we have to try to factor (t^2+7t+12)
We can make this into (t+3)(t+4)
Ah! Perfect! There is a t+3 in the denominator of the first fraction!
We can now cancel these out.
Now our equation looks like this:
(1 / t+4) * (1 / t+4)
This can also be written as 1^2 / (t+4)^2 = 1 / (t+4) ^2
So the correct option is the third one.
Answer:
D
Step-by-step explanation:
Since RS is parallel to PQ, gradient of RS is equal to gradient of PQ.
Gradient of RS
= gradient of PQ
y- intercept occurs at x= 0. Let the coordinates of the y-intercept of RS be (0, y).
Multiply both sides by -3:
y -6= 4
y= 6 +4
y= 10
Thus, the correct option is D.
