Answer:
Step-by-step explanation: Simplify the fractions, to do that, multimply 3 by the bottom number then add the top
16/5 should be the result
put 7 over 1 multiply across for each
Answer:
Part a) Is a growth function
Part b) The function's percent rate of change is 160%
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value or y-intercept
b is the base of the exponential function
If b> 1---> we have a growth function
if b< 1---> is a decay function
r is the percent rate of change
b=(1+r)
In this problem we have
The value of b >1
so
Is a growth function
Find the value of r
convert to percentage
Answer:
≈ £ 4584.38
Step-by-step explanation:
Firstly, we need to find the number of litres that Mr. Leonard needs to fill up his tank:
We know that there is already 450 litres in the 1200 litre tank, so he must need 1200 - 450 = 750 litres.
I'm not quite sure what the variable p means, but I'm going to assume that p represents the number of litres and that 81.5 is the price per litre in pounds.
So:
Total price = 81.5p
Total price = 81.5(750)
Total price = £61125
We have to remember though that the question is asking for the <em>discount</em> and not the <em>discounted price</em>, so:
61125 × 7.5%
61125 × 0.075 = 4584.375
≈ £ 4584.38
3/4 of 6/7. The of means multiplication.
= 3/4 * 6/7. 2 into 4 is 2 and 2 into 6 is 3.
= 3/2 * 3/7 No other number can divide, so we multiply out.
=9/14
That's the answer.
