Answer:
6 1/2 feet or 78 inches tall
Step-by-step explanation:
You have to multiply 4/8 by 7/1
First you multiply the nominators: 4 × 7 = 28
Then you multiply the denominators: 8 × 1 = 8
So the fraction would be 28/8 and it simplifies to 7/2
You can turn it into an improper fraction by seeing how many times 2 will go into seven evenly, which would be 6 times with 1 half left over
Therefore it would be 6 1/2 feet or 78 inches tall
We know that the profit from an item is the sale price minus the cost price. Thus,
1269 - 0.2x² - 830 - 398x
P(x) = -0.2x² - 398x + 439
Local maxima are located at the points where the first derivative of a function are 0
P'(x) = -0.4x - 398
398 = -0.4x
x = -995
There is only one maximum so the average value is -995
$680 was the original price!
100-62=38
258.40 x 100= 25840
25840/38=680
Answer:
to find compound interest
it is
p(1+r) ^n
p stands for principa
r is the rate (percentage)
n is the amount of years
820(1+3.5 ) ^ 5
100
chsnge the percentsge to a decimal and add it to 1.
820(1 + 0.035) ^ 5
820(1.035)^5
raise what is in the bracket to the power of 5 which is the amount of years
820× 1.19
=£975.80
im not good with simple interest,could someone else show her how to do it please
<span>For the graph y = 1, the slope of a line that is perpendicular would be infinity because it lies vertically. The slope of the line parallel to it will have the same slope with y=1 which is zero because it lies flat or horizontally. Hope this answers the question. Have a nice day.</span>
