Okay, I will give you the building blocks for solving this equation.

Now something you will need to remember is that a triangle will always add up to 180 degrees.

We can use y as that one unknown side in the triangle.

Knowing this, we can say (9x+16) + (6x+15) + y = 180

Then we can combine like terms like so : 15x+31+y = 180

There are two variables though. So we need more information.

Well, turns out we have the exterior angle of a straight line and the angle measures of a straight line must equal 180. We can now use (19x+3) + y = 180.

With both of these equations, you can now solve and find both of the angles

Can someone give me the answers for the number frame and how you did it, I’m confused :)

Answer:

16, 56, ...

Step-by-step explanation:

It looks like you have to put in each cell the multiplication of the row and the column, so the columns are 2, 7, 4 etc., and the row is always 8.

First cell: 2x8 = 16

Second cell: 7x8 = 56

and so on

It teaches you to apply the multiplication in a random sequence; you should be able to do this in your head.

Could you please look at this question?

Answer:

a. see attached

b. H(t) = 12 -10cos(πt/10)

c. H(16) ≈ 8.91 m

Step-by-step explanation:

The cosine function has its extreme (positive) value when its argument is 0, so we like to use that function for circular motion problems that have an extreme value at t=0. The midline of the function needs to be adjusted upward from 0 to a value that is 2 m more than the 10 m radius. The amplitude of the function will be the 10 m radius. The period of the function is 20 seconds, so the cosine function will be scaled so that one full period is completed at t=20. That is, the argument of the cosine will be 2π(t/20) = πt/10.

The function describing the height will be ...

H(t) = 12 -10cos(πt/10)

The graph of it is attached.

See part a.

The wheel will reach the top of its travel after 1/2 of its period, or t=10. Then 6 seconds later is t=16.

H(16) = 12 -10cos(π(16/10) = 12 -10cos(1.6π) ≈ 12 -10(0.309017) ≈ 8.90983

The height of the rider 6 seconds after passing the top will be about 8.91 m.

I need help with this one <br> 10x - 4.5 + 3x = 12x -1.1

Arisa [49]

Answer:

x=3

Step-by-step explanation:

1) 10x+1-1 = 12x-5-1, this becomes a new equation

Equation: 10x = 12x-6

2) 10x-12x = 12x-12x-6, this become a new equation

Equation: -2x = -6

3) Divide both sides by -2: -2x/2 = -6/2

4) Once you simplify, you will get x=3

Hope this helps!

The number of 8 oz glasses of milk in 1 gallon doesn't change and isn't a variable. Definitely answer NO to this one. With some reservations, I'd say that all the other three descriptions rate a YES.
