Answer:

Cupcakes: 50%

Cookies: 40%

Cakes: 10%

Step-by-step explanation:

150 + 120 + 30 = 300 (there are 300 baked goods)

150 out of 300 = 50%

120 out of 300 = 40%

30 out of 300 = 10%

Answer:

$50\%, \: 40\%, \: 10\%$

Step-by-step explanation:

$150:120:30$

$5:4:1$

$\frac{100}{5+4+1}$

$=\frac{100}{10}$

$=10$

$5 \times 10:4\times 10:1\times 10$

$50:40:10$

A certain recipe ask for 5/9 cup of granola. How much is needed to make 2/3 of a recipe

Masteriza [31]

I think you divide 5/9 divided by 2/3.
5/9 divided by 2/3=4/3 simplified=2/3.
Just know I'm terrible at math so this could be like totally off the hook crazy and wrong.

Martin is using unit cubes to build a tower in the shape of a rectangular prism. A decripion of the tower is listed the bottom l

leva [86]

Answer:

Volume of the completes tower = 160 units³

Step-by-step explanation:

Martin is using unit cubes to build a tower in the shape of rectangular prism.

Bottom layer of the prism is in the square shape.

Since number of unit cubes used in the bottom layer = 16

So, one side of the square base will measure = √16 = 4 units

Therefore, Length = width = 4 units

On this base, additional layers added on the top = 9

Therefore, height of the tower = (9 + 1) = 10 units (each layer having 16 cubes)

Volume of the tower = Volume of the rectangular prism

= Length × width × height

= 4×4×10

= 160 cubic units.

Volume of the completed tower will be 160 cubic units.

Which side lengths form a right triangle 30 POINTS!!

poizon [28]

Answer:

A. 3, 4, 5

Step-by-step explanation:

Option A:

LHS = 3² + 4² = 9 + 16 = 25

RHS = 5² = 25

(3, 4, 5) is a right triangle.

Option B:

LHS = 7² + 8² = 49 + 64 = 113

RHS = 9² = 81

(7, 8, 9) is NOT a right triangle.

Option C:

LHS = 3² + 9² = 9 + 81 = 90

RHS = √95² = 95

(3, 9, √95) is NOT a right triangle.

For the given pair of events A and B, complete parts (a) and (b) below. A: When a page is randomly selected and ripped from

Kitty [74]

Answer:

The two events are dependent.

the probability that events A and B both occur is:

$\frac{1}{2424}\times \frac{1}{2423}=1.7026052585\times 10^{-7}\ or\ 0.00000017$

Step-by-step explanation:

Consider the provided information.

Event A: When a page is randomly selected and ripped from a 2424-page document and destroyed, it is page 2020.

Event B: When a different page is randomly selected and ripped from the document, it is page 1616.

Part(A)

The occurring of one event affects the probability of the other event.

Because if we ripped one page then the probability of ripping second page will going to change as the size of sample space will decrease.

For example: The document has 2424 page, that means size of sample space is 2424. If we ripped another page, the sample size will be 2423. That means event B is depending on event A.

Thus, the two events are dependent.

Part(B)

The probability that events A and B both occur.

If we select a page randomly from 2424-page document, the probability will be: 1/2424

Now we have 2423 pages left in the document as one page is destroyed.

The probability of selecting another page is: 1/2423.

Thus, the probability that events A and B both occur is:

$\frac{1}{2424}\times \frac{1}{2423}=1.7026052585\times 10^{-7}\ or\ 0.00000017$
