This is a dimensional analysis problem. Because it’s water, you can use 1g = 1cm^3, so just convert Kg to g

Lillian had 2 two-liter bottles of soda, which she distributed equally between 10 glasses.
alexgriva [62]

<u><em>Answers:</em></u>

a. \frac{2}{5} liters/glass

b. 0.4 liters/glass

c. 400 ml/glass

<u><em>Explanation:</em></u>

<u>Part a:</u>

We are given that two bottles each holding 2 liters of soda

This means that the total amount of soda = 2 * 2 = 4 liters

To get the amount of soda in each glass, we will simply divide the amount of soda by the number of glasses (given the number of glasses is 10)

<u>Therefore:</u>

Amount of soda in each glass = \frac{4}{10} = \frac{2}{5} liters/glass

<u>Part b:</u>

We are now asked to express the amount in fraction. The simplest way to do this is to make the denominator a multiple of 10. The number of zeroes in the denominator will be equal to the number of digits after the decimal point

<u>Therefore:</u>

\frac{2}{5}=\frac{4}{10}=0.4 liters/glass

<u>Part c:</u>

Now, we know that 1 liter is equivalent to 1000 ml

<u>Therefore:</u>

0.4 liters = 0.4 × 1000 = 400 ml/glass

Hope this helps :)

Help plsss!! I’d rlly appreciate it :]

The volume of the Apple iPad Mini 2 is 12.561 in³.

The new volume of the  Pear-Apple is  24.53 in³.

The new volume of the  Pear-Apple is 5.3in³.

The scale factor to have a volume that is half that of the iPad Mini is 0.79.

The scale factor to have a volume that is double that of the iPad Mini is 1.26

<h3 /><h3>What is the volume of the Apple iPad Mini 2?</h3>

Volume = length x width x height

7.9 x 5.30 x 0.30 = 12.561 in³

<h3>What is the volume after the scale factors are applied?</h3>

Dimensions after the 1.25 scale factor is applied: (1.25 x 7.9) x (1.25 x 5.30) x (1.25 x 0.3)

= 9.875 x 6.625 x0.375 = 24.53 in³

Dimensions after the 0.75 scale factor is applied: (0.75 x 7.9) x (0.75 x 5.30) x (0.75 x 0.3)

= 5.925 x 3.975 x 0.225 = 5.3in³

Scale factor to have a volume that is double that of the iPad Mini : 2^{1/3} = 1.26

Scale factor to have a volume that is half that of the iPad Mini : 0.5^{1/3} = 0.79

K is the midpoint of Line JL, JL=4x-2 and JK=7. find X
ipn [44]
X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!
