Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.
BaLLatris [955]

Answer:

To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Step-by-step explanation:

hope its right

An isosceles triangle has an area of 32 cm2, and the angle between the two equal sides is 5π/6. Find the length of the two equal
taurus [48]
The area of a triangle can be determined by knowing 2 sides and their included angle of a certain triangle. Since both sides are equal, then they would just be denoted by a squared entity. This is done as follows:

A = x² sin∅
32 = x² sin (5*pi/6)

Make sure your calculator is in rad form.

32 = x² (1/2)
x = 8

Thus, each side is 8 cm.

Find the length of the missing side, given the information below. <br> PLEASE HELP I NEED THIS
Advocard [28]

Answer:

x = 2

UV = 9 ft

VW = 6 ft

WU = 5 ft

Step-by-step explanation:

The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:

P = UV + VW + WU

Now, we can substitute the values which we have:

20 = 4x + 1 + 8 - x + 2x + 1

We can combine like terms...

20 = 5x + 10

5x = 10

x = 2

Since UV is represented by 4x + 1, we can substitute in x to find its length.

UV = 4x + 1

UV = 4(2) + 1

UV = 6 + 1

UV = 9

We can do the same for the other two sides:

VW = 8 - x

VW = 8 - 2

VW = 6

WU = 2x + 1

WU = 2(2) + 1

WU = 4 + 1

WU = 5
