The area of a triangle is A=1/2*b*h

So we have 72=1/2*10*h

72=5*h

14.4=h

So the height is 14.4 units

Hope this helped!

Determine the slope and the y-intercept of the line represented by the equation y= -7/3×+3 slope: 7/9 ;y-intercept: 3 slope: 9/7

Mademuasel [1]

Answer:

$slope ⟹ \: - \frac{7}{9} \\ y \: intercept⟹ \: 3$

Step-by-step explanation:

The standard form of this equation is

$y = mx + c \\$

m stands for the gradient or the slope, and c represents the y-intercept

$y = mx + c \\ y = - \frac{7}{9} x + 3 \\ m = - \frac{7}{9} \: \\ and \: \\ \: y \: intercept \: = 3$

12. Determine the area of the shaded region. 12 in 12 in

vekshin1

Answer:

216/7 in²

Step-by-step explanation:

We know that:

Area of shaded region = Area of square - Area of circles
Radius of circle = 3 in
Area of circle = πr²
Area of square = s²

Solution:

Area of shaded region = Area of square - Area of circles
=> Area of shaded region = (12²) - 4(22/7 x 3 x 3)
=> Area of shaded region = (144) - 4(22/7 x 9)
=> Area of shaded region = (144) - 4(198/7)
=> Area of shaded region = 144 - 792/7
=> Area of shaded region = 144 x 7/7 - 792/7
=> Area of shaded region = 1008/7 - 792/7
=> Area of shaded region = 1008/7 - 792/7
=> Area of shaded region = 216/7 in²
