What is the square root of 64 over 225 with a negative outside of the radical?

1 answer:

5 0

The square root of (64/225) is the same as √64 / √225 .
That could make the whole thing easier.

Do you know what either of those separate square roots is ?

You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 .
You really know your stuff !

So now, the expression is √64 / √225 = 8 / 15 .

Oh, I almost forgot, it has a negative sign before it. OK,so the answer is - 8/15 .

Compare. -13/15 _ -5/6

Answer:

Your answer should be -13/15 < -5/6

Step-by-step explanation:

You would want to get the fractions to common denominators which in this case is 30.

So -13/15 = -26/30 (13*2 = 26, 15*2 = 30.)

And -5/6 = -25/30 (5*5 =25, 6*5 = 30.)

Since the fractions are also negative, the number closest to 0 would be the greater fraction. Which in this case would be -5/6. I hope this helps you! :)

Suppose "35" cars start at a car race. In how many ways can the top 3 cars finish the race?

Thepotemich [5.8K]

Answer:

The value is $\left 35 } \atop }} \right. P_3 = 39270$

Step-by-step explanation:

From the question we are told that

The total number of cars is $n = 35$

The number cars considered is $r = 3$

Generally the number of different top three finishes possible for this race of 35 cars is mathematically represented as

$\left n } \atop }} \right. P_r = \frac{n!}{(n - r) !}$

$\left 35 } \atop }} \right. P_3 = \frac{35! }{(35 - 3) !}$

$\left 35 } \atop }} \right. P_3 = \frac{35 * 34 * 33 * 32! }{32 !}$

$\left 35 } \atop }} \right. P_3 = 39270$

Rearrange f=3g+2 to make g the subject

Helen [10]

Minus 2 from bothsides
f-2=3g
divide both sides by 3
(f-2)/3=g
g=(f-2)/3

20 POINTS!!!! If eight is added to twice a number and the sum is multiplied by five result is the same as if the number is multi

Sauron [17]

<h3>The value of x is equal to -2.</h3>

5(2x + 8) = -8x + 4

Distributive property.

10x + 40 = -8x + 4

Add 8x to both sides.

18x + 40 = 4

Subtract 40 from both sides.

18x = -36

Divide both sides by 18

x = -2

Help ASAP!!! Identify the correct trigonometry formula to use to solve for x.

Alex787 [66]

Answer:

cos(55) = 11/x

Step-by-step explanation:

We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
