Answer:

Inequality that represents the amount paid by neighbors of Dani will be

x ≤ 8 + (4 + 16)

Step-by-step explanation:

Let the neighbors of Dani paid her to take care of their bird = $x

Danny spent on an afternoon snack = $4

She paid the amount for a new book = $16

Now the amount left with her is at least $8.

Therefore, inequality which represents the amount paid by her neighbor will be

x - 4 - 16 ≤ 8

x ≤ 8 + (4 + 16)

DiKsa [7]

Directly proportional to x.

<h3>What is propotionality?</h3>
  • In algebra, proportionality is the equality of two ratios.
  • A and B are in the same ratio as C and D in the formula a/b = c/d.
  • When one of a proportion's four quantities is unknown, a proportion is often built up to resolve the word problem.
  • By multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator, the equation can be solved.
  • Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

Acc to our question-

  • If two variables' ratios (yx)
  • (x and y) have the same value as a constant (k=yx)
  • therefore the ratio's variable (y) in the numerator is the sum of the other variable and the constant (y=k:x).
  • With a proportionality constant of k, it is claimed that y is directly proportional to x in this instance.

Hence,Directly proportional to x.

A cylinder has a height of 12 inches and a radius of 1.5 inches. What is its voulme? Round your answer to the nearest tenth. Use
Lerok [7]

Answer:

It's volume is of 84.78 cubic inches.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder with radius r and height h is given by:

V = \pi r^2h

A cylinder has a height of 12 inches and a radius of 1.5 inches.

This means that h = 12, r = 1.5

What is its volume?

V = \pi r^2h = 3.14(1.5)^2(12) = 84.78

It's volume is of 84.78 cubic inches.

Help me with my math don't get it! ;(
Vlad [161]

Answer:

B

Step-by-step explanation:

So, we know that this inequality has an "at most" in its phrase, therefore signifying the sign x <em>≤</em> 5. Since the x is in the left side without any negatives, so <em>the arrow goes left, and the circle is filled</em>. So, B.
