The weight of a person on Venus is directly proportional to their weight on Earth. Aperson weighing 120 pounds on Earth weighs 106 pounds on Venus.
Approximately how much would a person weighing 180 pounds on Earth weigh on
Venus?

Answers

Answer:

a person would weigh 158 pounds on venus

Step-by-step explanation:

weight of a person on venus is directly proportional to their weight on earth

i.e. weight on venus ∝ weight on earth

weight on venus = k * weight on earth

where k is the constant of proportionality

according to the question:

106 = k * 120

k = 106/120 = .88

thus,

person weighing 180 pounds on earth weighs on venus:

weight on venus = .88 * 180

= 158 pounds

A jar contains 24 coins: 10 quarters, 6 dimes, 2 nickels, and 6 pennies.What is the probability of randomly drawing _____ ?
1. a penny
2. a quarter
3. a coin that is not a penny

Answers

The probability of randomly drawing a penny is 6/24 or 1/4, since there are 6 pennies out of a total of 24 coins.

How to solve and What is Probability?

The probability of randomly drawing a quarter is 10/24 or 5/12, since there are 10 quarters out of a total of 24 coins. The probability of randomly drawing a coin that is not a penny is 18/24 or 3/4, since there are 18 coins that are not pennies out of a total of 24 coins.

Probability is the branch of mathematics that deals with measuring the likelihood or chance of an event or outcome occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

Probability theory is used to make predictions and informed decisions based on available data in various fields, including statistics, finance, engineering, and science.

It involves understanding and analyzing random events, and determining the likelihood of specific outcomes. Probability is an essential tool for decision-making in various applications, such as risk analysis, game theory, and quality control.

What is the length of the base of a triangle with height 11 cm and area 137.5 cm2?

Answers

Hi. So for this question, u need to work backwards.

A=bh/2
137.5=Bx11/2
137.5=11b/2
137.5=5.5b
137.5/5.5=25

So the base would be 25 cm. To check, do the actual formula from the start.

A=bh/2
A=25x11/2
A=275/2
A=137.5! The answer is right! The base is 25 cm! Hope that helps! :)

25% of what nember is 19

Answers

You would do 0.25x (x is the unknown total number)=19. It is because of is a multiply sign, so 0.25*x=19. Divide both sides by 0.25 and you get 76 as your answer.

25% OF WHAT = 25% OF X = .25 OF X = .25X
.25X = 19
X = 19 DIVIDED BY .25
X = 19 DIVIDED BY 1/4
X = 19 X 4
X = 76

Use the cubic model y = 10x3 − 12x to find the value of y when x = 9.
