<u><em>The complete question is</em></u>
The table shows how far a distance runner has traveled since the race began. What is her average speed, in miles per hour, during the interval 0.75 to 1.00 hours?
Time Elapsed (Hours) Miles Traveled (Miles)
0.50 2.00
0.75 3.50
1.00 4.75
Let
x ----> the time in hours
f(x) ----> the distance traveled in miles
so
we have
x (Hours) 0.50 0.75 1.00
f(x) (Miles) 2.00 3.50 4.75
we know that
To find the average speed, we divide the change in the output value by the change in the input value
the average speed is equal to
In this problem we have
Substitute
Answer:
$288
Step-by-step explanation:
If each square yard of carpet is $36, you just have to multiply 8 by that to get the total.
Answer:
the percentage profit is 20%
Step-by-step explanation:
Given that
Sean paid £10 for 24 chocolate bars
He sold all 24 chocolate bars for 50p each
we need to find out the percentage profit
Since he paid £10 and sale value is (24 × 0.50) i.e. £12
So, the percentage profit is
= (£12 - £10) ÷ (£10)
= 20%
Hence, the percentage profit is 20%
we can use
volume of cone formula
where
r' is radius of cone
h' is height of cone
we are given
The radius of the cone is half the radius of the cylinder
so,
The height of the cone is equal to the radius of the cylinder
so,
now, we can plug values into formula
we get
we can simplify it
so, option-C.........Answer
Answer:
y=25x+7
Step-by-step explanation:
The equation will be in the form of y=mx+c where m is gradient/slope and c is constant,
normally referred as y intercept.
Slope is given by dividing change in y by change in x
Slope=(57-32)/(2-1)=25
Therefore slope is 25
For the first term
32=25(1)+c
C=32-25=7
Therefore, the general equation will be y=25x+7
