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

alexgriva [62]

Answers:

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

b. 0.4 liters/glass

c. 400 ml/glass

Explanation:

Part a:

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)

Therefore:

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

Part b:

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

Therefore:

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

Part c:

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

Therefore:

0.4 liters = 0.4 × 1000 = 400 ml/glass

Hope this helps :)

Mark runs back and forth on a football field for a total of 3000 yards. How many miles did Mark run to the nearest tenth of a mi

gizmo_the_mogwai [7]

Answer:

1.7 miles.

Step-by-step explanation:

We have been given that Mark runs back and forth on a football field for a total of 3000 yards.

Since we know that 1 mile equals to 1760 yards. To find the number of miles Mark ran we will divide 3000 yards by number of yards in one mile (1760).

$\text{ Mark ran}=\frac{3000\text{ yards}}{1760\frac{\text{yards}}{\text{mile}}}$

$\text{ Mark ran}=\frac{3000\text{ yards}}{1760}\times \frac{\text{miles}}{\ext{yards}}$

After cancelling out yards from numerator and denominator we will get,

$\text{ Mark ran}=\frac{3000}{1760} \text { miles}}$

$\text{ Mark ran}=1.7045454545454545\text{ miles}}\approx 1.7\text { miles}}$

Therefore, Mark ran 1.7 miles on the football field.

Help pleaseeeeeeeeeeeeeeeeeeeeeee

Dima020 [189]

Answer:

B'C'D'

Step-by-step explanation:

The figure was just translated, without any deformation, these are similar figures... so their corresponding angles are the same.

Since it was just moved down by 4 units, none of the angles were changed, and none of the side lengths were changed.

Since vertex C' corresponds to vertex C, the angle B'C'D' corresponds to original angle BCD.

There are 12 students in a classroom, including the triplets joey, chloe, and zoe. If 3 of the 12 are randomly selcted to give s

forsale [732]

The probability of choosing Joey first is 1/12 .

If that happens, the probability of choosing Chloe next is 1/11 .

Then, the probability of choosing Zoe after that is 1/10 .

The probability of all these things happening is

(1/12) x (1/11) x (1/10)

= 1/1320 = 0.00076 = 0.076 percent
