The ratio of red cars to blue cars in a parking lot was 5:3 . If there was 40 red cars , how many blue cars were there ?

Answers

Answer 1

the answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24

Answers

Answer:

22 ft.

Step-by-step explanation:

First we can get the total change in elevation, which should be the final elevation minus the initial elevation:

(98ft)-(10ft)=88ft

Then, to get the change in 4 equal intervals, we can divide the total change in elevation by 4.

(88/4)ft=22ft

So during each of the four intervals, assuming they were four equal intervals, the diver descends 22ft.

In the expression 3v – 8, what is the variable?

Answers

Answer:

V is the variable

Step-by-step explanation:

Answer:a. v

Step-by-step explanation:

Given

Required

Identify the variable

Literary, variable means things that change in values;

Going by this definition, we have that:

3 -> This is not a variable because its value will always be 3

v -> This is a variable because its value can change once its value changes, the result of the expression will also change

- -> This is not a variable; it is an arithmetic operator to subtract

8 -> This is not a variable because its value will always be 8

Take for instance

When

Notice that there's a difference in both results;

This is as a result of v being a variable

What is the mean of 25, 27, 32, 29, 42?

Answers

Step-by-step explanation:

To find the mean, or average, you add all of the numbers and divide the sum by how many there are.

In this case, you add 25,27,32,29, and 42 and then divide the sum by 5.

25+27=52+32=84+29=113+42=155.

Then divide.

155/5=31.

JK = 7x + 9
JL = 114, and
KL = 9x + 9,
Find KL.

Answers

Answer:

KL= 63

Step-by-step explanation:

JK=7x+9 , JL=114 , KL=9x+9 ( if the points are on the same line and point J at the end point and K in the middle)

*J_______________________K___________________________L

JL=JK+KL

114=7x+9+9x+9

114-18=16 x

16x=98

x=98/16=6

KL= 9x+9

KL=9(6)+9

KL= 63

Answer:

[tex]8i^{22}[/tex] - 1

Explanation:

It's actually quite easy to tell which simplifies to a real number without working out the problem.

[tex]i^{2}[/tex] = -1

Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.

Some tips for fully solving the expression:

If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because [tex]i^{4}[/tex] = [tex](i^{2})^{2}[/tex] = [tex](-1)^{2}[/tex] = 1

If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.
