ANSWER

Find out the expression gives the percent of survey participants who chose swimming.

To proof

As given

75 girls at a summer camp were asked to complete a survey about their favorite outdoor activity.

27 girls chose swimming

32 girls chose hiking.

FORMULA

Percentage = \frac{Part\times100}{whole}

total girls  = 75

girls chose swimming = 27

put in the formula

= \frac{27\times100}{75}

= 36%

36% of survey participants who chose swimming

Hence proved

A, B and C are the vertices of a triangle.
DiKsa [7]

Answer:

see below

Step-by-step explanation:

To find the coordinates of the midpoints, add the x's and divide by 2 and add the y's and divide by 2.

The coordinates of D, the midpoint of AB, (1+3)/2 will be the x-coordinate and (4+0)/2 will be the y-coordinate.

D (2,2)

You could also see this on a graph, see image.

E, the midpoint of AC has the x-coordinate (1+-3)/2, which is -1 and y-coordinate (4+-2)/2 which is 1.

E is (-1,1)

Then we are able to calculate the slope of DE and BC.

To calculate slope, subtract the y's and put that on top of a fraction and subtract x's and put that on the bottom of a fraction. If the slopes are the same the segment are parallel.

Slope of DE:

(2-1)/(2--1)

= 1/3

Slope of BC:

(0--2)/(3--3)

=2/6

=1/3

The slopes of BC and DE are equal, so the segments are parallel.

(Alternatively, you could show that Triangle ABC and Triangle ADE are similar. Then find the segments parallel because corresponding angles are congruent.)

Which expression is equivalent to (x2 +9x – 1)(-4x + 3)? brainly
Andrews [41]

Answer:

- 4x³ - 33x² + 31x - 3

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis

= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms

= - 4x³ - 33x² + 31x - 3

Is the following relation a function? (1 point) Graph of x equals y squared, which results in a horizontal parabola centered on
Savatey [412]

The equation is not a function because in order for something to be a function you can't have 2 values of y for every x.
