Answer:
C
Step-by-step explanation:
One side;
7 x 8 = 56, the side parallel to it is also 56 as well, so 56(2).
Second(bottom) side;
8 x 4 = 32, the side parallel to it(the side above) is also 32 as well, so 32(2).
Third(front) side;
4 x 7 = 28, the side parallel to it(backside) is also 28 as well, so 28(2).
You add all those products to get the surface area:
<em>56(2) + 32(2) + 28(2)</em>
Answer:
4- 1/5 - 9/2
Step-by-step explanation:
Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is
1
number to the right of the decimal point, place the decimal number over
10
1
(
10
)
. Next, add the whole number to the left of the decimal.

2
Convert the mixed number
4
1
2
into an improper fraction first by multiplying the denominator
(
2
)
by the whole number part
(
4
)
and add the numerator (
1
) to get the new numerator. Place the new numerator (
9
) over the old denominator
(
2
)
.

Answer:C 2.0< t < 2.50
Step-by-step explanation:
Diameter of circular lake = 2 miles
Radius of the circular lake= 1 mile
Circumference of the circular lake = 2 pi
Speed of Joanna = 3mph
Time t= distance/ speed = circumference of lake / speed
t = 2 pi/ 3 = (2 × 3.142) / 3
t = 6.284/3 = 2.09
This is greater than 2 but less than 2.5, therefore statement C is correct
Answer:
(7 x 2 + 4x- 26)-(-7 x 2 - 3x + 15)
(7 x 2 + 4x -26) (7 x -2 + 3x - 15)
(14 + 4x -26) (-14 + 3x - 15)
(4x - 12) (3x - 29)
