Answer:
Option C
A = 390
Step-by-step explanation:
The image shows a figure composed of a rectangle and a triangle.
We know that the area of a rectangle is:
Ar = length * width
Then, using the data shown in the image, we have to:
Ar = 20(15) = 300
Then, the area of a triangle is:
So:
Finally the area of the figure is:
Answer:
D
Step-by-step explanation:
Surface area includes 2 squares and 4 rectangles
2(4²) + 4(6 × 4)
32 + 96
128 cm²
Answer:
Any line with the slope of 4/3 would be perpendicular.
Step-by-step explanation:
To find this, first solve the equation for y.
3x + 4y = 7
4y = -3x + 7
y = -3/4x + 7/4
Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/4 becomes -4/3) and then we change the sign (-4/3 becomes 4/3)
$4.5 since 1.26/7 is .14 and need 25 so it’s 4.5
