Answer: 22 signs
Step-by-step explanation:
First find out how many feet are in a mile.
A mile = 5,280 feet
There are signs every 240 ft so the number of signs are:
= 5,280/240
= 22 signs
<em>There is a sign at the beginning and one at the end both of which are already account for in the 22.</em>
12:15 = 8:X
X=cardboard box shadow
you find x by treating this equation like a proportion.
so 15(8)÷12=x
X=10
It depends on the number of the different colored marbles. if there are more black marbles, then there is a greater possibility of choosing that color.
A /3 + (a - 2) / 4 = 8
multiply through by 12:-
4a + 3(a - 2) = 96
7a = 102
a = 14.57 to nearest hundredth
Answer:
Volume = 480 cm³
Step-by-step explanation:
Volume = lwh
<em>*Split the shape into 3 rectangles.</em>
<u>Rectangle 1:</u> 4 x 4 x 8 = 128
<u>Rectangle 2:</u> 14 x 4 x 4 = 224
<u>Rectangle 3:</u> 4 x 4 x 8 = 128
<u>Total:</u> 128 + 224 + 128 = 480 cm³
