Answer:
150 ft
Step-by-step explanation:
The diagram shown gives us a picture of two similar right triangle.
The height of the man is similar to the height of the platform.
To find the height of the platform, multiply the height of the man by the scale factor.
Scale factor = the ratio of any corresponding sides of two similar triangles.
Scale factor = 100 ft ÷ 4 ft = 25
Height of man = 6ft
Therefore, height of platform = 6 ft × 25 = 150 ft
Answer:
Step-by-step Solution:
Simply change the denominators such that both denominators are the same. Then, add the fractions to get your result.
- 1/2 + 1/6
- => 3 x 1/2 x 3 + 1/6
- => 3/6 + 1/6
- => 4/6 = 2/3
Hence, the solution is 2/3.
The relationship is not proportional because the boys and girls are in different grades and they are in different activities.
First, you want to divide 420 by 180. Then, divide 54 by 180. Lastly, you want to multiply the answers of the two together.
-
420/180= 2.3
54/180= 0.3
2.3 * 0.3 = 0.69

Answer: x ≥ 0
Step-by-step explanation:
First, let's define the symbols used:
a < x (this means that a is strictly smaller than x)
a > x (this means that a is strictly larger than x)
a ≤ x (this means that a is smaller than or equal to x)
a ≥ x (this means that a is larger than or equal to x)
Now we have the statement "x is no less than 0"
Then x can be equal to zero, or larger than zero, but never smaller than zero.
Looking at the symbols above, we know that we need to use:
x ≥ 0
(this is equivalent to the statement)
