Answer:
-10
Step-by-step explanation:
(2+3)(5-7)
PEMDAS says do what is in the parentheses first
(5) ( -2)
Then multiply the parentheses
-10
Answer:
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x----> corresponding side of the larger trapezoid
y----> corresponding side of the smaller trapezoid
we have
substitute
step 2
Find the area of the larger trapezoid
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x----> area of the larger trapezoid
y----> area of the smaller trapezoid
we have
substitute
Answer:
A
Step-by-step explanation:
the point is at positive 8 and none of the other answers have positive 8
Answer:
Area = π r 2
C
360
where:
C is the central angle in degrees
r is the radius of the circle of which the sector is part.
π is Pi, approximately 3.142
