geniusboy [140]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Calculate 10% of total = 3 / 1.5 = 2

Multiply by 10x since 10% is 1/10 of 100%

2 x 10 = 20

What are the slope and the y-intercept of the linear function that is represented by the graph?
enyata [817]

The slope and the y-intercept of the linear function represented by the graph is given as follows:

The slope is two-thirds, and the y-intercept is –2.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Looking at the graph, when x = 0, y = -2, hence the y-intercept is of -2. The slope is given by <u>change in y divided by change in x</u>, hence considering that the graph also goes through (3,0), it is given by:

m = \frac{0 - (-2)}{3 - 0} = \frac{2}{3}

A convex hexagon has interior angle measures of 150 degrees, 3x, 2x, 4x + 24, and 3x + 50.
Anna [14]

Answer:

Step-by-step explanation:

The sum of the measures of a convex polygon of n sides is 180(n - 2).

A hexagon has 6 sides, so n = 6.

The sum of the measures of the interior angles of a hexagon is

180(6 - 2) = 180(4) = 720

(150) + (3x) + (2x) + (4x + 24) + (3x + 50)

Here's a problem. Only 5 measures are given.

This problem cannot be solved with the given information.

Write the general equation for the circle that passes through the points:
kiruha [24]

Answer:

The answer to your question is     x² + y² - 8x - 6y = 0

Step-by-step explanation:

Data

P (1, 7)

Q (8, 6)

R (7, -1)

Use the general equation of the Circle

                            x² + y² + Dx + Ey + F = 0

Process

1.- Substitute each point in the general equation and simplify

For P                                  

                          (1)² + (7)² + D + 7E + F = 0

                            1 + 49 + D + 7E + F = 0

                                 50 + D + 7E + F = 0

                                       D + 7E + F = -50             Equation l

For Q

                           (8)² + (6)² + 8D + 6E + F = 0

                            64 + 36 + 8D + 6E + F = 0

                            100 + 8D + 6E + F = 0

                                    8D + 6E + F = -100         Equation ll

For R

                           (7)² + (-1)² + 7D - E + F = 0

                           49 + 1 + 7D - E + F = 0

                                50 + 7D - E + F = 0

                                         7D - E + F = -50       Equation lll

Solve the system of equations, I do not include the process but the solutions are

D = -8   E = -6   F = 0

-Substitution

                       x² + y² - 8x - 6y = 0

The students in a class were each asked to name their favorite meal of the day. Which table could be represented by percentage b
sineoko [7]

Answer:

G

Step-by-step explanation:

I say G because when you look at the bar, the maximum is 100% and G is 20 in total. Therefore, the maximums are the same types and both can be divided by 10.
