Answer:

Step-by-step explanation:

Find all solutions to the equation.

7 sin^2(x) - 14 sin x + 2 = -5

7sin^2(x)-14 sin x+7 =0

sin^2(x)-2sin x+1 =0

(sinx-1)(sinx-1)=0

sinx=1

x=π/2+2pi*k, k=integer

I'm not going to say the answer because i want you to figure it out.
But here.

For Part A: There are 665 pounds of apples, 35 go in each box. You have to find out how many boxes there will be. How will you break apart 665 by 35? (Division) After that, you got your answer!

Part B: Just write down your answer from Part A.

Pleasee help me with this anyone..
vlabodo [156]

Answer:

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15

I bet I will mark you as a brainiest if u get this right
alexgriva [62]

Answer:

6%

Step-by-step explanation:

This is an honest guess just because you are not given the content of 2 out of the 3 bags. When starting at 100 percent of the makeup of the porridge you can then divide that by 3 to get the content of 1 bag. You will get around 33 then you find what 20% of 33 is which is closest to either 6 percent.
