B. 1/12

C. 1/30

D. 2/7

Answers

Answer 1

Answer:

The probability that the marble drawn will not be orange is option(A) $(5)/(7)$

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

Number of red marbles = 7 marbles

Number of orange marble =12 marbles

Number of yellow marble = 18 marbles

Number of purple marbles = 5 marbles

Total marbles = 7+12+18+5 = 42 marbles

Total marbles without orange marble = 7+18+5 =30 marbles

Probability = Number of favorable outcome / Number of total outcome

Probability that the marble drawn will not be orange = $(30)/(42)=(5)/(7)$

Hence, the probability that the marble drawn will not be orange is option(A) $(5)/(7)$

The price of an item yesterday was 180 Today, the price fell to 153 Find the percentage decrease.

Answers

The percentage decrease is 15%.

EXPLANATION

180 - 153 = 27 (price decrease)

10% of 180 = 18

5% of 180 = 9

18 (10%) + 9 (5%) = 27 (15%)

Final answer:

The price decreased by 27 and when you convert this into a percentage by dividing by the original price and then multiplying by 100, the result is a 15% decrease in the price.

Explanation:

To calculate the percentage decrease in the price, you first need to find out how much the price has fallen by. So subtract the new price (153) from the old price (180). This gives you 27.

Next, to convert this decrease to a percentage, you divide it by the original price (180) and then multiply by 100. So the calculation would be (27/180)*100 = 15%.

Therefore, the price of the item decreased by 15%.

A youth group is setting up camp. Rain is predicted, so the campers decide to build a fly, or rain cover, over their tent. The fly will be 12 feet high and 16 feet wide. The scouts are building the frame for the fly with two poles slanted and joined together at the top of the tent.

Answers

The image for this is attached for reference. This problem can be used by the Pythagorean equation. To make solving convenient, let us see only one part of the tent. Hence, one side is half of the tend width which is 16/2ft. Height is 12 ft. The unknown side is the hypotenuse. The answer is:

Write 210 and 252 as products of prime numbers.

Answers

210 = 21 times 10 = 7 times 3 times 5 times 2
252 = 126 times 2 = 63 times 2 times 2 = 21 times 3 times 2 times 2 = 7 times 3 times 3 times 2 times 2 = 7 times 3^2 times 2^2

Increase 120 centimetres by 24%

Answers

It is a simple problem where 120 centimeters need to be increased by 24%. The increased length can be found by:
120 * (24/100)
= 12 * (24/10)
= 288/10
= 28.8 centimeters
Then the total length of increase = 28.8 cm
Then the increased length = (120 + 28.8) cm
= 148.8 cm
So the length becomes 148.8 cm after it is increased by 24%.
