Answer:

choosing a green jelly bean out of a bag that contains 2 green jelly beans, 1 red jelly bean, and 5 yellow jelly beans

spinning a number less than 2 on a spinner that has four equal sections numbered from 1 to 4

choosing a spade out of a standard deck of cards that contains 13 hearts, 13 clubs, 13 diamonds, and 13 spades

Step-by-step explanation:

Probability: desired outcomes divided by total outcomes.

choosing a green jelly bean out of a bag that contains 2 green jelly beans, 1 red jelly bean, and 5 yellow jelly beans

2 green jelly beans in a set of 2+5+1 = 8 jelly beans

2/8 = 0.25.

So this is part of the answer.

rolling a number less than 3 on a six-sided die

2 options(1 or 2) out of 6 possible values

2/6 = 0.3333...

Not 25%.

spinning a number less than 2 on a spinner that has four equal sections numbered from 1 to 4

1 options(1) out of four possible sections(1,2,3,4)

1/4 = 0.25

So this is part of the answer.

choosing an Oregon state quarter out a bag that contains 4 California state quarters, 3 Oregon state quarters, 6 Texas state quarters, and 3 New York state quarters

3 Oregon quarters out of 4+3+6+3 = 16 quarters

3/16 = 0.1875

Not 25%

choosing a spade out of a standard deck of cards that contains 13 hearts, 13 clubs, 13 diamonds, and 13 spades

13 cards(spades) out of a set of 52 cards

13/52 = 0.25

So this is the third option

  • height: 60 ft

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = (1/2)bh

Filling in the numbers you are given, you get ...

  1500 = (1/2)(5/6h)(h)

  3600 = h^2 . . . . . . . . . multiply by 12/5

  60 = h . . . . . . . . . . . . . .square root

  b = 5/6·60 = 50 . . . . . . base is 5/6 of height

The measures of the base and height are 50 ft and 60 ft, respectively.

A garment dealer buys for Rs.10,000 and spend Rs.800 on freight. He seeks the entire stock for Rs.12,960. Find his loss/profit p
jeyben [28]

Answer:

Profit percentage=20\%.

Step-by-step explanation:

Given: A garment dealer buys goods for  \text{Rs.}\:10,000 and spend \text{Rs.}\:800 on freight. He seeks the entire stock for \text{Rs.}\:12,960.

To find:  His loss/profit percentage.

Solution:

We have,

Cost price of goods =\text{Rs.}\:10,000

Spent on freight =\text{Rs.}\:800

So, total cost of goods=\text{Rs.}\:10000+\text{Rs.}\:800=\text{Rs.}\:10,800

Selling price of entire stock =\text{Rs.}\: 12,960.

Now, Profit =\text{Selling price}-\text{Cost price}

So, Profit =\text{Rs.}\:12, 960-\text{Rs.}\:10,800=\text{Rs.}\:2160

Now,

\text{Profit\:\%}= \frac{\text{Profit}}{\text{Cost price}} \times 100\%

\implies\text{Profit\:\%}= \frac{2160}{\text{10,800}} \times 100\%

\implies\text{Profit\:\%}= \frac{2160}{108}\%

\implies\text{Profit\:\%}= 20\%

Hence, profit percentage =20\%.
