Find the unit rate. Enter your answer as a mixed number.
lesya [120]

The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour.

<h3>What is the rate of change?</h3>

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

A fertilizer covers 5/8 square feet in 1/6 hour.

5/8 square feet ⇒ 1/6 hour

Multiply both sides by 6

6 × 5/8 square feet ⇒ 6/6 hour

30/8 square feet ⇒ 1 hour.

Hence "The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour".

Log (w2+21) - log (10)
UNO [17]

Answer:

w =7\ or\ w =3

Step-by-step explanation:

Given

The right question is:

\log(w^2+ 21) = \log(10w)

Required

Solve for w

\log(w^2+ 21) = \log(10w)

Cancel log on both sides

w^2+ 21 = 10w

Equate to 0

w^2 - 10w+ 21 = 0

Split

w^2 - 3w - 7w+ 21 = 0

Factorize

w(w - 3) - 7(w-3) = 0

Factor out w - 3

(w - 7)(w-3) = 0

Solve for w

w - 7 = 0\ and\ w - 3 = 0

w =7\ or\ w =3

What is the location of (-3,-4) after it has been reflected over the x axis? 1) New ordered pair 2) Explain what changes in the
geniusboy [140]

Answer:

The new ordered pair would be (-3, 4)

Step-by-step explanation:

The change would just be a change of the symbol of the y value. This is because a reflection over the x-axis will not change the x value and will give you a y on the other side.
