melomori [17]

Answer:

32 Large lemonade

Step-by-step explanation:

A container holds four gallons of lemonade a large lemonade contains 16 oz how many large Lemonade's Cuisine Restaurant sell before they run out of lemonade

1 gallon = 128 oz

Hence, 4 gallons = x

x = 4 × 128 0z

x = 512 oz of Lemonade

If

1 large lemonade = 16 oz

16 oz = 1 large lemonade

512 oz = x

x = 512/16

x = 32 large lemonades

The restaurant will.sell 32 large lemonade

On a particular day, 112 of 280 passengers on a particular DTW-LAX flight used the e-ticket check-in kiosk to obtain boarding pa
irakobra [83]

Answer :

0.2322

Step-by-step explanation:

Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4

p = 0.4

1 - p = 1 - 0.4 = 0.6

Number of samples, n = 8

P(x = 4)

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 4) = 8C4 * 0.4^4 * 0.6^4

P(x = 4) = 70 * 0.0256 * 0.1296

P(x = 4) = 0.2322432

P(x = 4) = 0.2322

If triangle ABC is similar to triangle EHG, find the measure of angle EHG.
Ksju [112]

<u>First we need to find all the interior angles.  So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180. </u>

2x + x + 60 = 180

<u>Now lets start to solve. First let's subtract the 60 from both sides. </u>

2x + x = 120

<u>Now we need to add the x's together. </u>

3x = 120

<u>Now we must divide the 120 by 3 to get x by itself. </u>

x = 40

<u>Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so </u><em><u><EHG would be equal to 80. </u></em>

<u>ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do! </u>

Select the correct answer. Shape 1 and shape 2 are plotted on a coordinate plane. Which statement about the shapes is true? A. S
IceJOKER [234]

Answer:

Since I cant say which answer due to no graph, I'll tell you How to do so.

Step-by-step explanation:

if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.

if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other

A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.

D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.
