Answer:
a
Step-by-step explanation:
The altitude from N to LM
N is vertically below LM, thus the units can be counted directly, that is 6 units
The of the first multiples of 21 is 21, 42, 63, 84, 105
Answer:
D
Step-by-step explanation:
$2.50 is the initial charge, so it's not affected by the amount of miles of the trip, therefore the x, which represents miles, would not be next to $2.50. This eliminates A
x has no relation to 2.50 so it wouldn't be in parentheses together, that eliminates B
You have to add 2.50 to the total, not subtract it from the total. That eliminates C
By process of elimination we end up with the answer being D
Answer:
Area=14.28 Perimeter= 14.28
Step-by-step explanation:
Area of a circle = (3.14) * r^2
radius = diameter/2
radius = 4/2
r = 2
A = (3.14) * 2^2
A = (3.14) * 4
A = 12.57
since it's a half circle though, 12.57/2 = 6.29
the area of the rectangle is bh, 4*2 = 8
6.29 + 8 = 14.28
area = 14.28
perimeter of a circle, or circumference = 2(3.14)r
C = 2(3.14) * 2
C = 6.28 * 2
C = 12.57
but again, since it's a half circle, 12.57/2 = 6.29
perimeter of a rectangle = 2(l + w)
p = 2(4 + 2)
p = 2(6)
p = 12
but because the perimeter is what's on the outside, we don't count the side connecting to the circle, so it'd be 12 - 4 = 8
6.29 + 8 = 14.28
perimeter = 14.28
