The measures of the angels of ΔRST are in the ratio 2.4.9 What are the measures of the angels

Answers

Answer 1

Answer: Sum of interior angle of a triangle is 180 degrees.
2x + 4x + 9x = 180
15x = 180
x = 180/15 = 12
2x = 2 x 12 = 24
4x = 4 x 12 = 48
9x = 9 x 12 = 108
the measures of the angles are : 24 degrees, 48 degrees ,108 degrees

Which equation is related to the equation shown?x + 3 = 12

A.

x = 12 + 3

B.

x = 12 ÷ 3

C.

x = 12 − 3

D.

x = 12 • 3

Answers

The answer is:

C) x = 12 - 3

Work/explanation:

To solve, subtract 3 on each side:

$\rightarrow\hspace{13} \sf{x+3 = 12}\n\n\n\rightarrow\hspace{13}\sf{x=12-3}\n\n\n\rightarrow\hspace{13}\sf{x=9}$

The equation that is related to the equation shown is x = 12 - 3.

C, because it's the opposite of the actual equation.

Explain two different squares that can be made using the number 9

Answers

Answer: $1$ and $81$ .

Step-by-step explanation:

Since, we have number $9$ with help of which we have to find a square.

If we divide 9 by 9 then we will obtain 1 which is itself a square.

That is, $(9)/(9) = 1$

Now, If we multiply 9 by itself we obtain 81, which is the square of 9.

That is, $9* 9 = 81$

Note: We can also make other squares by using number 9.

9/9=1
9x9=81.
keep in mind that a square root is any number multiplied by itself to get another number

H 24 inches The volume of a cylinder can be found by using the formula v Bh. Which expression can be used to determine B, the area of the base of this hatbox in square inches? (24) H 82.12 J 122.8

Answers

The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h. Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr². The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12. therefore B=12²π.

I hope this helps.
