The cafeteria uses rectangular trays with a raised edge around them. The area of the flat surface of each tray is 228 Inches squ

ared and its length is 19 inches. What is the perimeter of the tray, where the raised edge is?
To find the width, use the formula w = StartFraction A Over l EndFraction, where w represents the width, A represents the area and l represents the length. To determine the perimeter, use the formula P = 2 l + 2 w, where P represents the perimeter, l represents the length, and w represents the width.

Alice is baking a cake. She doesn’t intend to eat it, but tells you half of what you find is yours. She tells the same thing to
tankabanditka [31]

Answer: a) P = 0.5, b) P = 0.07

Step-by-step explanation:

Hi!

Lets call X₁ the time at which you arrive, and X₂ the time at which Bob arrives. Both are random variables with uniform density in the interval [0, 60] (in minutes). Their joint distribuition is uniform over the square in the image, with value P = 1/(60*60) = 1/3600.

a) For you to get more cake than Bob, you should arrive earlier. This event is A = { X₁ < X₂ }, the shaded triangle in the figure.The area of this event (set) is half the total area of the square, so P(A) = 0.5.

It makes sense, beacuse its equally probable for you or Bob to arrive earlier, as both have uniform density over the time interval.

b) In this case you arrive later than Bob, but less than 5 minutes later. So the event is B = { X₂ < X₁ < (X₂ + 5) } . This is the gray shaded area in b) part of the image. Its area is the difference two triangles (half square - blue triangle), then the probability is:

P(B) = 0.5 - \frac{(0.5*55^2)}{3600} =0.07

Help me please thank you​
Elan Coil [88]

Answer:

23/3

Step-by-step explanation:

They already give you the area of one base, which is great! The volume of a rectangular prism is l · w · h, and they've already done h · l for you.

All you do is multiply the two values you see on screen.

4/3 · 23/ 4

= 23/3

(Since there is a 4 both on top and on the bottom, you can cross them out, instead of multiplying everything across)

I hope this helped!

During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were
Triss [41]

Question

During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were: A. Desserts B. Appetizers  C. entrees

Answer:

A)Desserts = 25 %

B)Appetizers = 32.5 %

C)Entrées =  32.5 %

Step-by-step explanation:

<u>Given:</u>

Number of appetisers = 13

Number of entrees =   17

Number of  desserts = 10

<em><u>A. percentage of the dishes he delivered were Desserts</u></em>

Percentage  of Desserts = \frac{\text{ Number of dessert}}{\text{ total number of dishes}} \times 100

Total number  of dishes = 13 + 17 + 10 = 40

Percentage  of Desserts = \frac{10}{40} \times 100

Percentage  of Desserts = 0.25 \times 100

Percentage  of Desserts  =  25 %

<em><u>B. percentage of the dishes he delivered were Appetizers </u></em>

Percentage  of Desserts = \frac{\text{ Number of Appetizers  }}{\text{ total number of dishes}} \times 100

Percentage  of Desserts = \frac{13}{40} \times 100

Percentage  of Desserts = 0.325 \times 100

Percentage  of Desserts  =  32.5 %

<em><u>C. percentage of the dishes he delivered were Entrées </u></em>

Percentage  of Desserts =  \frac{\text{ Number of Entrees }}{\text{ total number of dishes}} \times 100

Percentage  of Desserts = \frac{17}{40} \times 100

Percentage  of Desserts = 0.425 \times 100

Percentage  of Desserts  =  42.5 %
