Are 2/4 and 3/6 equivalent ratios?

Answers

Yes, because 2:4 and 3:6 both mean 1:2

Answer:

Yes it is an equivalent ratio

Step-by-step explanation:

So you have 2/4 and you need to divide 2 by everything. So 2 divided by 2 which equals 1 and then 2 divided by 4 which equals 2. So you know have an answer of 1/2. But you still need to figure out if 3/6 is and equivalent ratio. Do the same steps. 3 divided by 3 which equals 1 and 6 divided by 3 which equals 2. So both of the ratios equal 1/2 which now we are able to say they are equivalent ratios. :)

Frankie’s electric bill total is $48 and contains three charges: a charge for electricity used, 5% tax on the charge for electricity used, and $6.30 in fees. Which statements are true?

Choose exactly two answers that are correct.

A. The equation that represents the price, e, of the electricity is e + 0.05e + 6.30 = 48.

B. The equation that represents the price, e, of the electricity is 0.05e + 6.30 = 48.

C. The cost of the electricity before taxes or fees is $39.71.

D. The cost of the electricity before taxes or fees is $834.

Answers

A. The equation that represents the price, e, of the electricity is e + 0.05e + 6.30 = 48
C. The cost of the electricity before taxes or fees is $39.71.

e + 5% of e + 6.30 = 48
e + 0.05e + 6.30 = 48
1.05e = 48 - 6.30
1.05e = 41.70
e = 39.71

39.71 + 5%(39.71) + 6.30 = 48
39.71 + 1.99 + 6.30 = 48
48 = 48

If x=7 and y=-3

12-5xy +9x2y + 15-2y2

Answers

Just plug in x = 7 and y = -3 in place of x and y, respectively

$12-5xy +9x^2y + 15-2y^2\n\n12-5(7)(-3) +9(7)^2(-3) + 15-2(-3)^2\n\n12 - (-105) + (-1323) + 15 -18\n\n12 + 105 - 1323 + 15 - 18 = \boxed{-1209}$

Your answer is -1209

Sara Just Turned 18 Years Old. She Spent 4/9 Of Her Life Living In Rochester,NY. How Many Years Did Sara Live In Rochester?

Answers

1/9 of 18 is 2.

So 4/9 of 18 = 4*2 = 8

So Sara lived in Rochester for 8 years.

8 years

Further explanation

Given:

Sara just turned 18 years old.

She spent $(4)/(9)$ of her life living in Rochester, NY.

Question:

How many years did Sara live in Rochester?

The Process:

From the information above, we make a suitable diagram as follows:

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = ? \ years$

Four of the nine parts are the question. The nine full parts below are Sara's ages.

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 18 \ years$

Let us calculate how many years did Sara live in Rochester.

$\boxed{ \ 9 \ parts = 18 \ }$
$\boxed{ \ 4 \ parts = ? \ }$

$\boxed{ \ = (4)/(9) * 18 \ }$

We crossed out 9 and 18.

$\boxed{ \ = 4 * 2 \ }$

Thus Sara has lived in Rochester for $\boxed{\boxed{ \ 8 \ years \ }}$

- - - - - - - - - -

Quick Steps:

$\boxed{ \ = (4)/(9) * 18 \ }$

$\boxed{ \ = 4 * 2 \ }$

$\boxed{\boxed{ \ 8 \ years \ }}$
