**Answer 1**

**Answer:**

x=50

y=25

**Step-by-step explanation:**

So for this triangle we can use trig. To find side x (the hypotenuse) we can do sin60 degrees. *remember SOHCAHTOA, so sin is opposite over hypotenuse.

sin60degrees=(25 * sqrt of 3)/x

multiply each side by x to get xsin60degrees=25*sqrt of 3. Then divide both sides by sin60degrees. Plug that in a calculator and you should get 50.

For side y, well you can use the characteristics of 30-60-90 triangles and by doing this we know that the short leg of this type of triangle is HALF of the hypotenuse and half of 50 is 25. If you didn't know this you could still use the cos of 60 degrees and get 25 as well.

Emily has 6 gallons of water josh has 23 quarts of water. How many more points does Emily have more than josh

### Answers

**Answer:**

2 pints

**Step-by-step explanation:**

To determine the amount of pints that Emily has more than Josh, gallons and quarts have to be converted to pints and the value is then subtracted

1. **Convert gallons and quarts to pints**

1 gallon = 8 pints

6 gallons = 8 x 6 = 48 pints

1 quart = 2 pints

23 quarts = 2 x 23 = 46 pints

**2. Determine the difference in the amount of pints Emily has and the amount Josh has**

48 pints - 46 pints = 2 pints

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place

### Answers

**Step-by-step explanation:**

*I think you have forgotten to attach the question. *

*Anyways....*

In order to find the area of a circle use the formula:

**π**[tex]r^{2}[/tex]** ** Where r is the radius

For example the radius is 3cm. The area of the circle will be:

π × [tex]3^{2}[/tex]

Since you have taken pi as 3.142...

3.142 × [tex]3^{2}[/tex]

3.142 × 9

= 28.278

In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.

= **28.3 **[tex]cm^{2}[/tex]
