The locomotive is 40 ft long.
40 ft = 40 * 12 in. = 480 in.
The locomotive is 480 inches line.
The model is 16 inches long.
480/16 = 30
The real locomotive is 30 times longer than the model.
A window on the locomotive is 30 times wider than a window on the model.
Answer:
<h2>The coordinates will be (-8, -6), (-4, -6), (10, 8), (6, 8).</h2>
Step-by-step explanation:
As per the given image, the co-ordinates are, P(-4, -3), Q(-2, -3), R(5, 4) and S(3, 4).
Since, the scale factor is 2 and centered at the origin, we need to multiply the co-ordinates with 2 in order to get the co-ordinates of the figure after dilation.
Hence, the co-ordinates will be
P = (-8, -6)
Q = (-4, -6)
R = (10, 8)
S = (6, 8).
A set of pencils sells for 1.75 and costs 0.40 to make
if 500 sets are sold...
500(1.75) = 875...this is revenue
500(0.40) = 200....this is expenses
profit = revenue - expenses
profit = 875 - 200
profit = 675
20% of the profit goes to the school...
0.20(675) = $ 135 <=== this is what goes to the school
Answer:
D
Step-by-step explanation:
142 ÷ 2 = 71
D. ( 100÷2) + (40÷2) + (2÷2)
50 + 20 + 1
71
Answer:
x = -14
Step-by-step explanation:
x/2 = -7
Multiply each side by 2 to get the x by itself
x = -7 * 2
x = -14
