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

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.

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.

Which is a y-intercept of the continuous function in the table? (0, –6) (–2, 0) (–6, 0) (0, –2)

Answers

Answer:

(0, - 6)

Step-by-step explanation:

The y- intercept is where the function crosses the y- axis.

This occurs when x = 0 , thus

From the table when x = 0, f(x) = - 6

The y- intercept is therefore (0, - 6 )

The sum of 20.7 and a number is 50.5.

Answers

20.7 +x = 50.5

To solve it
x= 50.5 - 20.7
x = 29.8

Answer:

x = 29.8

Step-by-step explanation:

x represents the unknown number

20.7 + x = 50.5

x + 20.7 - 20.7 = 50.5 - 20.7

x = 50.5 - 20.7
