Answer:

30,340 feet above sea level is the correct answer.

Step-by-step explanation:

To find the difference to between the two sea levels, subtract the lowest quantity (or the elevation of the Dead Sea) to the largest quantity (or the elevation of Mt. Everest.)

However, in this situation, you must also add the quantity of the above sea level to the subtraction, since the lower quantity is above sea level.

29,028 - 29,028 = 0

Now, we must subtract the lower quantity of 1,312.

0 - 1,312 = -1,312

If this was to be represented on a number line, the difference between our work relates to the absolute value, or the amount of spaces a number is from 0. Even though this is a negative number, you can take away the sign (if there is any) from in front of the number, and the absolute value will still be 1,312.

To find the total difference, add 29,028 to 1,312.

29,028 + 1,312 = 30,340

Therefore, our final answer is 30,340 feet above sea level.

Hope this helps! :)

Answer:

40$

Step-by-step explanation:

if maria has 465$ in her account and she withdrew 250$ makes 215 but it also says she withdrew 175 so 215 subtract 175 makes 40 dollars if she uses 45 dollars to fill her car up she still only has 40 dollars i hope this helps

Answer:  $40

Step-by-step explanation: If Maria has 465 dollars and withdraws takes out subtracts $250 she has $215 after that she takes out or subtracts $175 so than she has $40. I think the answer is $40  but I am not so good  at math so I'm not sure

Answer:

50.23 and 50.24 are both rational numbers.

Step-by-step explanation:

Rational numbers can be written like a ratio.

●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.

●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)

●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.

50.23

= 50 + 23/100

= 50•(100/100) + 23/100

= 5000/100 + 23/100

= 5023/100

50.23 is equal to 5023/100.

50.24 = 5024/100 = 2512/50 = 1256/25

Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)

Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

Answer:

4

Step-by-step explanation:

Substituting into the slope formula,

\(\frac{-3-1}{2-3}=4\)

Answer:

Step-by-step explanation:

(3,1) and (2,-3)

Use the slope formula.

Slope:

\(\longrightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }\)

\(\sf{y_2=(-3)}\\\\\sf{y_1=1}\\\\\sf{x_2=2}\\\\\sf{x_1=3}\)

\(\sf{\dfrac{(-3)-1}{2-3}}=\sf{\dfrac{-4}{-1} }=\boxed{\sf{4}}\)

Therefore, the slope is 4, which is the correct answer.

Good luck! Hope this helps!

Answer:

the answer for this question should be 6 because remember we need to substitue n by -3 so first we need to solve the exponent one so we replace it.

-3^2= 9

-3 times -3= 9 and remember this rule when we multiply an negative times a negative is positive so it would be 9 for n^2 so we need to add 9+-3 and we get an answer of 6 so 6 is the correct answer and remember if the base is an negative and the exponent is even the answer is positive but if it is odd it would be negative.

hopefully 6 is the correct and have a great day.

Answer:6 7 3 4 6 8

Step-by-step explanation:

19. The y intercept and x intercept is 2 and -3 respectively

20. The y intercept and x intercept is 2 and 8 Respectively

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

The equation ,-2x +3y = 6

the y intercept is obtained when x = 0

-2(0) + 3y = 6

3y = 6

y = 6/3

y = 2.

The x intercept is obtained when y = 0

-2x = 6

x = 6/-2

x = -3

therefore the y and x intercept for the graph are 2 and -3 respectively.

For equation x+4y = 8

when x= 0

4y = 8

y = 8/4

y = 2

when y = 0

x = 8

therefore the y and x intercept are 2 and 8

Answer:

the product of 3.8 and 6.9 is 26.22.

Step-by-step explanation:

The product of 3.8 and 6.9 can be found by multiplying the two numbers. Using a calculator or long multiplication, we get:

3.8 x 6.9 = 26.22

Therefore, the product of 3.8 and 6.9 is 26.22.

It is important to note that when finding the product of two decimal numbers, we need to make sure to place the decimal point correctly in the final answer. To do this, we count the total number of decimal places in the two numbers being multiplied, and then place the decimal point in the answer that many places from the right. In this case, both numbers have one decimal place, so the answer has one decimal place as well.

5 3-digit numbers that have three equal digits.

we need to apply the principle of inclusion-exclusion to account for the fact that some 3-digit numbers may be counted multiple times.

any 3-digit number that has three equal digits will be counted twice once as a 3-digit number with two equal digits and one different digit, and once as a 3-digit number with three equal digits.

There are 5 choices for the digit that is repeated, and 1 way to arrange the digits, so there are 5 3-digit numbers that have three equal digits.

Therefore, we need to subtract 5 from the total number of 3-digit numbers that have two equal digits and one different digit.

60 number are 3-digit numbers that have two equal digits and one different digit.

Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter.

The given digits are,

1, 2, 3, 4, 5.

Since, to find the 3 digits numbers which are written by using given digits, and have two equal digits and one different digit,

Here order of arrangement matters.

Use permutation formula,

From 5 digits, 3 are chosen,

Ways of arrangement = ⁵P₃  

= 5! / (5-3)!

= 5! / 2!

= 5 x 4 x 3 x 2! / 2!

= 60

There are total 60 different ways, in which numbers can be arranged.
