If 60% of a number is 144 what is the number?

Mathematics
1 answer:
Sonja [21]3 years ago
8 0

Answer:

240

Step-by-step explanation:

So 60/100 x (n) = 144

We should be able to multiple both sides by 100, and divide each side by 60 to get our answer.

n = 144 x (100/60) which then equals 240.

ASAP help I don’t know the answer
Nady [450]

Answer:

6

Step-by-step explanation:

It appears you have vertical angles. The rule with angles is that no matter what, vertical angles are always congruent (or the same). This means you would have to set up the equation to solve for "b" as:

70 - 2b = 28 + 5b

You could solve this manually, but Desmos graphing calculator is faster. Simply type this in and replace b with x and it will give you the answer, which is 6. Hope this helps!

The roots of the equation 2x^2+8x-7=-2 are?
olchik [2.2K]
<span>2x^2+8x-7=-2
</span><span>2x^2+8x - 5 = 0

using the formula:- x = [-8 +/- sqrt(8^2 - 4*2*-5) ]  / 4
                                  =  -2 +/- sqrt 104)/2
                                  = 0.5495 ,   -4.549

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.
Oksanka [162]
The ordered pairs would be,

(1, 8.5)
(2, 8)
(3, 7.5)
(4,7)
(5, 6.5)
(6, 6)

I got the ordered pairs from the question since it stated that the length of the candle decreased .5 every hour. I just corresponded the hour to the length of the candle.

I hope this helped!

Brainliest answer is always appreciated!
