The height of a mountain is 24,000 feet. Of this height, 22,000 feet is above sea level and 2,000 feet is below sea level. Which set of integers represents the heights of the mountain above and below sea levels? pick the right expression that equal the word problem.
A. { 22,000, 2,000}

B. { 22,000, 2,000}

C. { 22,000, 2,000}

Answers

The answer is A {+22,000 -2,000}

This is because sea level is counted as 0 on a topographical map and any distance below sea level is counted in -ft. So if you the problem is amount above sea level to amount below sea level then you have 22,000 above sea level which would be +22,000 ft. And two thousand below. Then you just put that in the brackets “{}” and you are done.

In a game the player wins if he rolls a 4 on a number cube. If the number cube is rolled 24 times, then what is a reasonable prediction for the number of unsuccessful rolls?

Answers

Answer:  20

============================================

Explanation:

If we want to roll a 4, then theoretically we have a probability of 1/6 of that happening. This is because there's 1 face that has "4" labeled on it, out of 6 faces total.

If we roll the cube 24 times, then we expect 24*(1/6) = 24/6 = 4 instances of the "4" show up. Of course, due to the random nature of this event, it's not guaranteed. So that's why we use the "expect" there.

We expect 4 times to get successful rolls, which means we have 24-4 = 20 unsuccessful rolls. This value (20) is also an expected or predicted value, and not a guarantee.

Number line with closed circle on 6 and shading to the right.
Number line with open circle on 6 and shading to the left.

Answers

Answer:

Number line with closed circle on 6 and shading to the right.

Step-by-step explanation:

The graph that shows all the possible values for a number that is at least 6 is : Number line with closed circle on 6 and shading to the right.

What is a number line?

"It is a pictorial representation of numbers on a straight line."

For given question,

We need to find the number line that shows all the possible values for a number that is at least 6.

This means the possible values of a number are greater than and equal to 6.

We know that, on the number line open circles are used for numbers that are less than or greater than (< or >)

And the closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).

Since, we need to find the values of a number that are greater than and equal to 6.

So, there must be closed circle at 6 and for the values greater that 6 there must be shading to the right of 6.

Therefore, the graph that shows all the possible values for a number that is at least 6 is : Number line with closed circle on 6 and shading to the right.

Plz Help 30 points:
Part A: Larry earned $11 walking his neighbors' dogs on Saturday. He earned some extra money on Sunday doing the same thing. Write an expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

Part B: Larry was able to walk 4 more than twice as many dogs as his friend Kyle. Write an algebraic expression to represent the number of dogs Larry walked compared with Kyle.

Answers

Answer:

Part A: T stands for total money earned and S stands for money earned on Sunday

T = 11 + S

Part B: We know Larry walked AT LEAST twice the amount of dogs than Kyle. So, L standing for Larry and K for Kyle:

L = 2(K)

But, it tells us he walked twice, plus 4 more. So our final equation will be:

L = 2(K) + 4

Step-by-step explanation:

The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

The algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

Given data

Larry earned $11 walking his neighbors' dogs on Saturday

Also, he earned some extra amount say x dollars on Sundays

let the total earnings be y

Therefore the total earnings can be expressed as

y= 11+x

next part:

It is given in the question that

Larry was able to walk 4 more than twice as many dogs as his friend Kyle  have.

Let number of dogs Kyle has = x

and Let Larry walks y miles.

According to the  given data

y = 2x + 4

Therefore , the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

Hence, The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.

And,  the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .
