Peggy has saves 9,215. If she is paid $45 an hour, how many hours did she work?

1 answer:

4 0

First we set up our equation. We know she has $9,215, and she gets paid $45 an hour. So our variable would be the hours she has to work.

45n=9,215

Since we don't have any like terms to combine, we just divide both sides by 45, to isolate the variable.

n=204.8 Hope this helped!

A tv costs £800 plus VAT at 20% what is the total cost of the tv?

slamgirl [31]

hello friend ☺

Given :

TV cost = 800 £

VAT = 20 %

Amount of VAT

= 20% of 800

= 800 × 20 /100

= 160 £

So Total cost of TV

= original price + VAT

= 800 + 160

= 960 £

Thanks ❤

If p:q=2/3:3 and p:r=3/4:2/3 calculate the ratio p:q:r. Giving the answer in its simplest form

adelina 88 [10]

Answer:

Given

if p:q=2/3:3 and p:r=3/4:1/2, calculate the ratio p:q:r giving your answer in its simplest form

We need to find the ratio p:q:r

Given p:q = 2/3 : 3 = 2/3 / 3 = 2/9

and p : r = 3/4 : 1/2 = 3/4 / 1/2 = 3/2

Now p/q = 2/9 and p/r = 3/2

We need to make p equal numerators so we get

p/q = 2/9 x 3/3 = 6/27 and

p/r = 2/3 x 3/2 = 6/4

Therefore p : q : r = 6 : 27 : 4

What is the equation that represents the line?

Kryger [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 6) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = $\frac{-3+6}{2+2}$ = $\frac{3}{4}$ , thus

y = $\frac{3}{4}$ x + c ← is the partial equation

To find c substitute either ot the 2 points into the partial equation

Using (2, - 3), then

- 3 = $\frac{3}{2}$ + c ⇒ c = - 3 - $\frac{3}{2}$ = - $\frac{9}{2}$

y = $\frac{3}{4}$ x - $\frac{9}{2}$ ← equation of line
