Atriangle is 20 in tall and 5 in wide. if it is reduced to a width of 1 in then how tall will it be?

The triangle should be 4 inches tall

Step-by-step explanation:

We can write a proportion to solve.  Put the height over the width

20           x

=

5              1

Using cross products

20*1 = 5*x

20 = 5x

Divide by 5

20/5 = 5x/5

4 =x

The triangle should be 4 inches tall

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
