£40 and £20
Step-by-step explanation:
let the parts be 2x and x (2:1)
2x+x=£60
or, 3x= £60
or, x= £20
2x=2×£20=£40
x=£20
Given a vetex (h,k) of a function parabola, the corresponding equation is:

With (h,k)=(2,5) we get the equation:

In order to find a, we use the given point (3,7) like this:

The equation is then:
Answer:
6 more laps
Step-by-step explanation:
Hello!
First you find how far he went
So he we 96 kilometers there and back
96 + 96 = 192
It took him 8 hours to go 192 kilometers
To find the average speed you divide these two
192/8 = 24
So his average speed was 24 kilometers an hour
The answer is 24
Hope this helps!
Answer:
60°
Step-by-step explanation:
Sum of angles of triangle = 180°
x + 40 + 80 = 180
x + 120 = 180 {Subtract 80 from both sides}
x = 180 - 120
x = 60°
