1 answer:

5 0

56/25= $2.24 per gallon (Wow that's a lot)

32.05/15= $2.14 per gallon (Better....but not really)

It would be best to buy 15 gallons for $32.05

A magazine subscription costs $29.88 for 12 issues or $15.24 for 6 issues. Which subscription costs more per issue? How much mor

Valentin [98]

Answer:

The magazine that cost $15.24 for 6 issues cost more by $0.60/60 cents.

Step-by-step explanation:

Since $15.24 is 6 issues each and you need to even out the issues add $15.24+$15.24 then you would get $30.48, because its 15.24 each 6 add them both and it would be 12 issues. And the first issue $29.88 for 12 issues is only $29.88 while the other is $30.48 so the one with 6 issues/the second cost more than the first.

60 cents more because 29.88+60=30.48.

Help please will give brainlist <br><br> Find x+y

Leno4ka [110]

Answer:

Step-by-step explanation:

2y-5 and 95 are vertical angles so they are equal

$2y - 5 = 95$

$2y = 100$

$y = 50$

3x and 144 form a linear pair angle so

$3x + 144 = 180$

$3x = 36$

$x = 12$

x=12 and y=50 so

$12 + 50 = 62$

The function LaTeX: f\left(x\right)=2\cdot4^xf ( x ) = 2 ⋅ 4 xcan be used to represent an exponential growth curve. What is the

nikklg [1K]

Option B: 4 is the multiplicative rate of change of the function

Explanation:

The exponential growth function is $f(x)=2(4)^x$

We need to determine the multiplicative rate of change of the function.

First, let us determine the values of function.

x y

1 8

2 32

3 128

4 512

Since, the multiplicative rate of change of an exponential function is the number by which the next term is increasing or decreasing.

Thus, the multiplicative rate of change of the function is given by

Multiplicative rate of change of the function = $\frac{32}{8} =4$

Multiplicative rate of change of the function = $\frac{128}{32} =4$

Multiplicative rate of change of the function = $\frac{512}{128} =4$

Thus, the multiplicative rate of change of the function is 4

Therefore, Option B is the correct answer.
