A paint mixture was formed by mixing exactly 3 colors of paint. By volume, the mixture was x% blue paint, y% green paint, and z%
sergeinik [125]

Answer:

Both statements are sufficient to answer the question

Step-by-step explanation:

Given:

- The paint mixture has following proportions:

 Total volume of paint = T

 Blue:  x*T / 100

 Green: y*T/100

 Red: z*T/100

Find:

Statement 1: x = y

Statement: z = 60

Which of the above statement is sufficient to calculate the amount of green paint used

Solution:

Statement 1:

- The amount of blue paint used is:

                    1 gallon = x*T / 100

- x = y,

                    1 gallon = y*T / 100

Hence,

                    Amount of green paint used is 1 gallon

- The statement is sufficient

Statement 2:

- The amount of red paint used is:

                    3 gallon = z*T / 100

                    T = 300 / z = 300 / 60 = 5 gallons

                    T = R + B + G

                    G = T - R - B

                    G = 5 - 3 - 1

                    G = 1 gallons

Hence,

                    Amount of green paint used is 1 gallon

- The statement is sufficient

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you
bija089 [108]

Answer:

A=6.33\ cm^2

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

C=2\pi r

we have

C=\frac{28}{3.14}\ cm

\pi=3.14

substitute the values

\frac{28}{3.14}=2(3.14)r

r=\frac{28}{19.7192}\ cm

r=1.42\ cm

step 2

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

substitute the values

A=(3.14)(1.42)^{2}

A=6.33\ cm^2

Solve the system of equations. <br><br> 10x+y=−20 <br><br> y=2x2−4x−16<br><br> ( , ) and ( , )
Sladkaya [172]
I will go about solving this using the elimination method.

First, convert the equations.

10x + y = -20
4x + y = -12

Second, find the easiest variable to get rid of and get rid of it!  (In this case, y)  We will subtract to get rid of y.

6x = -8

Third, you want to solve the equation.

6x = -8 (divide by 6)
x = -1 \frac{1}{3}

Fourth, solve for y by inserting the answer for x into one of the equations.

10(-1 \frac{1}{3}) + y = -20
-13 \frac{1}{3} + y = -20 (subtract -13 \frac{1}{3})
y = -6 \frac{2}{3}

The solution for this system of equations is (-1 \frac{1}{3}, -6 \frac{2}{3}).
