Lisa and Ann are eating a box of crackers. Lisa eats 3/6 of the box,and Ann eats 1/4 of the box.How much of the box did the two

Rufina [12.5K]

<h2>Lisa and Ann ate 3/4 of the box together</h2>

<em><u>Solution:</u></em>

Given that,

Lisa and Ann are eating a box of crackers

$Lisa\ ate = \frac{3}{6}\\\\Ann\ ate = \frac{1}{4}$

<h3><u>How much of the box did the two girls eat together?</u></h3>

$Together\ eaten = Lisa\ ate + Ann\ ate\\\\Together\ eaten = \frac{3}{6} + \frac{1}{4}\\\\Together\ eaten = \frac{1}{2} + \frac{1}{4}\\\\Together\ eaten = \frac{1 \times 2}{2 \times 2} + \frac{1}{4}\\\\Together\ eaten = \frac{2}{4} + \frac{1}{4}\\\\Together\ eaten = \frac{3}{4}$

Thus Lisa and Ann ate 3/4 of the box together

Mr. Chin went to a store where he spent one-half of his money and then $14 more. He then went to another store where he spent on

ElenaW [278]

Answer:

Before going to the first store he had $ 112.

Step-by-step explanation:

Before going to the first store Mr. Chin had all his money, which we will call by "x". After the first store he had:

y = x/2 - 14

He then went to a second store and he spent all his money in a way that:

y/3 - 14 = 0

Because after that store he had no money left. So we can use the second equation to solve for y and then use that value to solve for x, that is the amount of money he had before going to the first store. We have:

y/3 = 14

y = 14*3 = 42

From the first equation:

42 = x/2 - 14

x/2 - 14 = 42

x/2 = 42 + 14

x/2 = 56

x = 112

Before going to the first store he had $ 112.

One year Perry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitch

Blizzard [7]

Answer:

z score Perry $z=-1.402$

z score Alice $z=-1.722$

Alice had better year in comparison with Perry.

Step-by-step explanation:

Consider the provided information.

One year Perry had the lowest ERA of any male pitcher at his school, with an ERA of 3.02. For the males, the mean ERA was 4.206 and the standard deviation was 0.846.

To find z score use the formula.

$z=\frac{x-\mu}{\sigma}$

Here μ=4.206 and σ=0.846

$z=\frac{3.02-4.206}{0.846}$

$z=\frac{-1.186}{0.846}$

$z=-1.402$

Alice had the lowest ERA of any female pitcher at the school with an ERA of 3.16. For the females, the mean ERA was 4.519 and the standard deviation was 0.789.

Find the z score

where μ=4.519 and σ=0.789

$z=\frac{3.16-4.519 }{0.789}$

$z=\frac{-1.359}{0.789}$

$z=-1.722$

The Perry had an ERA with a z-score is –1.402. The Alice had an ERA with a z-score is –1.722.

It is clear that the z-score value for Perry is greater than the z-score value for Alice. This indicates that Alice had better year in comparison with Perry.

Need help ASAP not sure how to simplify this could someone pleade comment answer

madam [21]

Answer:

8 (3/4)

Step-by-step explanation:

convert everything into improper frantions

-3 1/2 = -7/2

-12 1/4 = -49/4

common denominators

-7/2 = -14/4

solve

-(14/4)-(-49/9)

two negative cancel out to make a positive

-(14/4)+(49/9)

35/4

35 divided by 4 = 8.75 = 8 3/4
