Answer:
132 cm²
Step-by-step explanation:
Consider the shape as a trapezoid with a rectangle added on top.
The area of the trapezoid is (7+19)/2 × 8 =104
The area of the rectangle is 7×4 = 28
Add the two areas: 104+28= 132
OR consider the shape as a tall rectangle with the two triangles added to the sides.
The area of the rectangle is 7(4+8) = 84
The area of the triangles is 8(19-7)/2= 48
[Each triangle is 24 cm²]
Add those areas
84+48=132
Same result: 132 cm²
Answer:
okay so im not sure which is being round so i'll do both
if you are going to round the miles and gallons:
278.2 to 278 because the decimal is below 0.5
19.6 to 20 because the decimal is above 0.5
278/20 = 13.9 which you would round to 14 because the decimal is above 0.5
if you are only going to round the answer:
278.2/19.6 = 14.193877551 which you would round to 14 because the decimal is below 0.5
so regardless of what you do, <u> your answer will be 14</u>
That is false, miss. It IS the radius.
Answer:
x=15
Step-by-step explanation:
This is an equilateral triangle. That means all sides are equal and all angles are equal
An equilateral triangle has angle measurements of 60 degrees
60 =4x
Divide each side by 4
60/4 = 4x/4
15 =x
Find 2 coordinates on the graph : (0, -20) and (10, 10)
Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3
Slope = 3
y-intercept = (0, - 20)
Equation : y = 3x - 20
Since the right hand side is shaded, the equation is y > 3x - 20.
