I think the answer is 7. 5 miles

Answer:

7.5mph (1 d.p)

Step-by-step explanation:

First, I worked out what a third of an hour was to match the unit mph.

60 minutes / 3 = 20 mins

A third of an hour is 20minutes so two thirds of an hour is 40 minutes.

But as we know, one third as a decimal is 0.33(reccuring) so therefore two thirds as a decimal is 0.66, which we need to use.

Now, we need to remember the equation. Speed = distance / time

Place the facts we already know in place.

speed = 5miles / 0.66 (using a calculator.)

speed = 7.5mph (1 d.p)

Hope this helps and you have a good day!

0.6 times 17,151 = 1029.06

To Check:

1029.06 out of 17,151

That's pretty much equal to 1/17

As a percentage, 1/17 is 6%

Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45

y=x-32

Step-by-step explanation:

y=mx+b where m is the slope and b is the y-intercept.

slope=change in y/change in x

y=5x+b --> choose a random point

(7,3) ---> 3=5(7)+b=35+b

b= -32

y=x-32

The correct answer is X = -32
