the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.

x+(2x+15)+the measure of angle Q should equal 180.

Since everything is addition, the parenthesis can be removed.

x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Unfortunately I don't really know what to do from here, but I hope it helped at least a little.

Answer:

8 days

Step-by-step explanation:

The total cost includes $55 flat rental fee which is one time cost only as not given everyday so we subtract it from $123 and divide $(123-55) with per day cost that is $8.50 which gives 8 as answer so Val spent 8 days on vacation.

Tlaloc pumped up 56 balls. He pumped up 5 dodge balls for every 9 other balls. Complete the table.
Radda [10]

The number of dodgeballs Ttaloc pumped up is 20.

The number of other balls Ttaloc pumped up is 36.

The orginal number of the total ball is 14.

<h3>What are ratios?</h3>

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The number of dodgeballs Ttaloc pumped up = (5/14) x 56 = 20

The number of other balls Ttaloc pumped up = (9/14) x 56 = 36.

A circle has a circumference of 34 54 cm. What is the area of the circle to the nearest whole centimeter? Use 3.14
inysia [295]

Answer:

<h2>9498.5 m</h2>

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

2\pi \times r

So we can put the equation this way,

3454 = 2\pi \times r

So we can solve for 'r'

3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r   =   \frac{3454}{6.28}  \\ r = 550

Now we have radius and we can solve for the area of the circle,

\pi \times  {r}^{2}

3.14 \times 550 \times 550  \\  = 949850

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)
