Answer:

The correct answer for this equational ratio is x = 5

Step-by-step explanation:

In order to calculate for x, we must create the necessary ratios

\frac{16}{20} = \frac{45-5x}{5x}

Cross multiply to get

900 - 100x = 80x

900 = 180x

x = 5

Range : 2 (y-values)

14:

Not a function, if you draw a vertical line through one point, it will hit two others.

Domain : -3

Range : 4 , 0, -4

15:

It is a function, no two points in any vertical line.

Ivan will rent a car for the weekend. He can choose one of two plans. The first plan has no initial fee, but costs $0.90 per mil
borishaifa [10]

Answer:

$337.50

Step-by-step explanation:

The computation of the number of miles need to drive for determining the same cost is given below:

Let us assume the miles be x

So for the first plan, the equation is

= $0.90x

And for the second plan, the equation is

= $75 + $0.70x

Now equate this

0.90x = $75 + 0.70x

0.90x - 0.70x = $75

0.20x = $75

x = $75 ÷ 0.20

= 375 miles

Now the same cost would be

For plan A and plan B

0.90x = $75 + 0.70x

0.90(375) = $75 + 0.70(375)

$337.5 = $75 + $262.50

$337.50 = $337.50

vivado [14]

Answer:

3418.1 square inches (to the nearest tenths place)

Step-by-step explanation:

Volume of a Cylinder =\pi r^2 h

Base Radius, r =8 inch

Height, h=17 inch

Therefore:

Volume of the Cylinder

=\pi* 8^2*17\\=3418.1$ square inches (to the nearest tenths place)
