6 of 30 is the ratio 6 to 30 or 6/30.

6/30 reduces to 1/5

The survey shows that 1/5 of the students attend summer camp.

Lindsie is painting on a canvas with dimensions of 3 ft by 4 ft. She wants to make a display model for a gallery that has twice
love history [14]

Answer:

B. 1.4 feet

Step-by-step explanation:

Let, the amount of increase be 'x' ft.

Since, the length and width of the canvas are 4 ft and 3 ft respectively.

Thus, area of the canvas, A_{c} = length × breadth = 4 × 3 = 12 ft²

Since, the area of display model is twice the area of the canvas. We have,

A_{d} = 2 × A_{c}

i.e. A_{d} = 2 × 12

i.e. A_{d} = 24 ft².

As, the length and width of the canvas are increased  by 'x'.

The, length and width of the display model are (x+4) ft and (x+3) ft.

So, we get,

A_{c} = length × breadth = (x+4) × (x+3) = x^{2} +7x+12

Since, A_{d} = 24 ft²

i.e.  x^{2} +7x+12 = 24

i.e.  x^{2} +7x-12=0

Solving the quadratic equation, we get,

i.e. x = -8.4 and x= 1.4

Since, the value of x cannot be negative.

Thus, x = 1.4 feet.

(25 points) A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The stan
zimovet [89]

Answer:

C = 0.65M+19.65

Step-by-step explanation:

Given the the standard charge S (in dollars) given by the function

S = 0.40M + 15.75, where M is the number of miles driven.

Also the insurance charge I (in dollars) is given by the function

I = 0.25M + 3.90

If C is the total charge (in dollars) for a rental that includes insurance, then:

C = S + I

Substitute the given function into the expression:

C = 0.40M + 15.75 + 0.25M + 3.90

Collect like terms

C = 0.40M+0.25M+15.75+3.90

C = 0.65M+19.65

<em>Hence an equation relating C to M is expressed as C = 0.65M+19.65</em>
