Answer:
24m and 25m.
Step-by-step explanation:
By Pythagoras Theorem:
h^2 = x^2 + 7 ^2 where h is the hypotenuse and x is the other leg.
But x and h are consecutive integers
so h = x + 1 and:
(x + 1)^2 = x^2 + 49
x^2 + 2x + 1 - x^2 = 49
2x + 1 = 49
2x = 48
x = 24
So the 2 lengths are 24 and 25.
Answer:
Step-by-step explanation:
The ratio of boys to girls is 12 to 16, 12:16 or 12/16 (all different ways this can be written). The fraction form 12/16 can be reduced by dividing by the greatest common factor. Both 12 and 16 are divisible by 4, so the reduced fraction is 12/4 over 16/4 = 3/4. In other words, there are 3 boys for every 4 girls in the class.
Rearranging this into slope-intercept form, we see that the y-intercept is -7.
I believe it is 4, but i am not sure.
