Answer:
92.5 cm²
Step-by-step explanation:
Lets take this step by step
Bottom rectangle is 2 by 5, so then 2*5 = 10
Large rectangle is 8 by 9, so 8*9 = 72
The triangle is 7 by 3, you get the 7 by subtracting the 5 side from the square because using the square you can tell that the height is 9 - something.
The 5 you get is from subtracting the cut part that you might have made because the height of that is 2, therefore you cut off 2 from 7 making it 5
Triangle area is h*b / 2, therefore 7*3 = 21/2 = 10.5
Add them all together, 10.5 + 10 + 72 and you get 92.5
Answer:
B. The point of intersection of the triangle's three angle bisectors.
Step-by-step explanation:
Answer:
y = - 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + b ← is the partial equation
To find b substitute (- 2, 5) into the partial equation
5 = 8 + b ⇒ b = 5 - 8 = - 3
y = - 4x - 3 ← equation of line
Answer:
$28.5
Step-by-step explanation:
25% of 38 is 9.5. You subtract 9.5 from 38 to get 28.5.
You basically just see the denominator, try to convert it into 100. Then create a number line from 1-100. Then use the numerator of the converted fraction and place it on the number line.
