Vera is using her phone.Its battery life is down to 2/5,and it drains another 1/9 every other. How many hours will her battery l

Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

$1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

$\frac{1}{9}\cdot x=\frac{3}{5}$

Now we will solve for x.

$x=\frac{3\cdot 9}{5}=\frac{27}{5}$

$x=(5+\frac{2}{5})hours$

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

$60\cdot \frac{2}{5}=24\text{minutes}$

Therefore, remaining battery life will be 5 hours and 24 minutes.

Write an expression that represents the area of the rectangle. Remember A = LW

Iteru [2.4K]

Answer:

b) 9x² - 3x

Step-by-step explanation:

Area of a rectangle = Length × Width

Area for the rectangle = 3x - 1 × 3x

Area = $(3x-1)(3x)$

Step 1. Multiply by combining like terms

3x · 3x = 9x²

Step 2. Multiply -1 by 3x

-1 · 3x = -3x

Step 3. Combine 9x² and -3x

9x² - 3x

Camellia earned $160 over the summer. If you put 80% of earnings into her savings account and spent 75% of the rest on a gift fo

In-s [12.5K]

Answer: She has left over $8.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>Camellia earned $160 and you put 80% of earnings into her savings account: </em>

So, to obtain this number we have to multiply Camellia's earnings by 0.80 (the percentage in decimal form, 80 /100 = 0.80)

$160 x 0.80 = $128 (savings)

If we subtract the number obtained to Camellia's earnings:

$160 -$128 = $32 (money left without purchasing a gift)

<em>She spent 75% of the rest on a gift for her </em>

The rest is $32, so we have to multiply it by the percentage in decimal form (75/100=0.75)

$32 x 0.75 (decimal form) = $24

And finally, subtract that number to the original rest.

$32-$24 = $8

She has left over $8.
