Answer:
30 feet
Step-by-step explanation:
A ratio of 4:3 means that if one part can be represented by x, the original height is equal to 4 * x and the mural height is equal to 3 * x. This is because the ratio of original : mural is 4 : 3, so if one part = x, we have 4 * x : 3 * x. Therefore,
original mast height = 40 feet
4 * x = original mast height = 40 feet
divide both sides by 4 to get x
x = 10 feet
3 * x = mural mast height = 3 * 10 feet = 30 feet
The Pattern B is the twice of the Pattern A. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Item 11 In the table,
Pattern A uses the rule "add 5" and Pattern B uses the rule "add 10".
Pattern A 10 15 20 25 30
Pattern B 20 30 40 50 60
Then the Pattern B is the twice of the Pattern A.
Then the correct option is C.

Answer:
Step-by-step explanation:
When "y varies directly with x" this means that:
where k is a number we need to find out (called the constant of proportionality if you care about that).
We can figure out what k is because they tell us when y= -252, x=84. Substituting those values into our equation we get:
and therefore:
.
So our equation or formula between y and x is:
.
So when x = 74, then:
Plug in x2 to x2 and x to x and solve
