No, it's not.

15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.<span />

never [62]

Answer:

Kyle would save more using his 15% off of $1000 coupon.

Explanation:

15 ÷ 100 • 1000 = 150

1000 - 150 = $850

$150 is the amount the 15% coupon took off.

$850 is the amount Kyle will pay.

vs.

1000 - 80 = $920

An aquarium tank can hold 6300 liters of water. There are two pipes that can be used to fill the tank.The first pipe alone can f

liq [111]

Answer: it will take them 28 minutes to fill the tank.

Step-by-step explanation:

The first pipe alone can fill the tank in 84 minutes. This means that the rate at which the first pipe fills the tank per minute is 1/84

The second pipe can fill the tank in 42 minutes by itself. This means that the rate at which the second pipe fills the tank per minute is 1/42

If they work together, they would work simultaneously and their individual rates are additive. This means that their combined rate of filling the tank would be

1/84 + 1/42

Assuming it takes t hours for both pipes to fill the tank working together, the working rate per minute would be 1/t. Therefore,

1/84 + 1/42 = 1/t

3/84 = 1/t

t = 84/3

t = 28 minutes

Find all solutions of the equation in the interval [0, 2π).

skelet666 [1.2K]

Answer:

x=0

Step-by-step explanation:

$4 \cos(x) = - \sin {}^{2} (x) + 1$

$4 \cos(x) = 1 - \sin {}^{2} (x)$

$4 \cos(x) = \cos {}^{2} (x)$

$4 \cos(x) - \cos {}^{2} (x) = 0$

$\cos(x) (4 - \cos(x) ) = 0$

$\cos(x) = 0$

$x = 0$

$4 - \cos(x) = 0$

$\cos(x) = 4$

There is no solution here because cosine is undefined it the range is not between -1 and 1 so the only answer is 0.
