If the value is 100% of ' v ' today and it decreases 8% in a year,
then the value will be 92% of ' v ' 1 year later. That's 0.92v .

Ramon earns $1,735 each month and pays $53.10 on electricity. To the nearest tenth of a percent, what perfect of ramons earnings

Alenkinab [10]

Answer:

$\boxed{3.1 \, \%}$

Step-by-step explanation:

The formula for calculating percentage is

$\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%$

The "part" is the electricity payment.

The "whole" is Ramon's earnings.

$\begin{array}{rcl}\text{\% of earnings} & = & \dfrac{53.10}{1735} \times 100 \, \% \\\\& = & \mathbf{3.1 \, \%}\\\end{array}\\\boxed{\mathbf{3.1 \, \%}} \text{ of Ramon's earnings are on electricity}$

This Question: 1 pt

zhenek [66]

$\huge{ \mathfrak{ \underline{ Answer }\: \: ✓ }}$

Angles forming linear pair are :

$\mathrm{\angle EFG \: \: and \: \: \angle GFH}$

And we know, they are supplymentary

$\mathrm{\angle EFG \: + \: \angle GFH} = 180 \degree$
$3n +1 9 \degree+ 2n + 36\degree = 180 \degree$
$5n + 55\degree = 180\degree$
$5n = 125\degree$
$n = 25\degree$

So, the measures of the given angles are :

$\mathrm{\angle EFG } = 3n + 19$
$\mathrm{ \angle EFG = (3 \times 25\degree) + 19}$
$\mathrm{ \angle EFG = 75 \degree+ 19\degree}$
$\mathrm{ \angle EFG = 94\degree}$

And

$\mathrm{ \angle GFH = 2n + 36}$
$\mathrm{ \angle GFH = (2 \times 25\degree) + 36\degree}$
$\mathrm{ \angle GFH = 50\degree + 36\degree}$
$\mathrm{ \angle GFH = 86\degree }$

Myra combined the like terms in the algebraic expression correctly.

olga55 [171]

The answer would be the first one, combining 8 and -2

This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)

If you combine these you will get 6x^2 [8+(-2)=6]
