Answer:

164 respondents answered "yes"

69 respondents answered "yes"

126 respondents answered "yes"

Step-by-step explanation:

Let's take these problems one at a time.

First problem: 195 Juniors and 215 Seniors. 2 out of 5 answered "yes".

Now let's first find the total number of students.

Total Students  = 195 + 215

Total Students = 410

Now 2 out of 5 also means the 2/5 or 40% of the students answered yes.

To see how many said yes, we simple multiply the total number of students to the value of 40% or 0.40.

Total Students that answered "yes" = 410 x 0.40

Total Students that answered "yes" = 164

Second Problem: 125 Juniors and 220 Seniors. 0.80 answered "no".

Same process, we first look for the total number of students.

Total Students = 125 + 220

Total Students = 345

Now 0.80 or 80% of them said "no".

We take the total number of students and multiply the number of students to the value of 80% or 0.80.

Total Students that answered "no" = 345 x 0.80

Total Students that answered "no" = 276

Now to find out how many answered "yes", we subtract the total number of students to the students that said "no".

Total Students that answered "yes" = 345 - 276

Total Students that answered "yes" = 69

Third Problem 200 Juniors and 160 Seniors. 35% answered "yes"

Same process, we first look for the total number of students.

Total Students = 200 + 160

Total Students = 360

To see how many said yes, we simple multiply the total number of students to the value of 35% or 0.35.

Total Students that answered "yes" = 360 x 0.35

Total Students that answered "yes" = 126

 <br>What is the measure of ∠XYZ? Show your work to support your answer.<br><br>​
Shalnov [3]

3x + 20 = 5x - 16

3x - 5x = -16 - 20

-2x = -36

x = -36/-2

x = 18

The measure of angle xyz can also be said to be the measure of angle y.

So, y = (3•18 + 20)

y = 54 + 20

y = 74°

The measure of angle xyz = 74°.

Dorian is spreading mulch on his triangular flowerbed. If the base is 8 feet and the height is 6 feet. How many square feet of m
katovenus [111]

Answer:

24 square feet

Step-by-step explanation:

Given:

Dorian is spreading mulch on his triangular flowerbed.

The base is 8 feet.

The height is 6 feet.

Question asked:

How many square feet of mulch will he need for the flowerbed?

Solution:

The base of  triangular flowerbed = 8 feet.

The height of  triangular flowerbed = 6 feet.

now, to find how many square feet of mulch he will need for the flowerbed, we will find area of the triangular flowerbed:-

As we know:

Area\ of\ triangle=\frac{1}{2} \times base\times height

                           =\frac{1}{2} \times8\times6\\\\ =\frac{48}{2} \\ \\ =24\ square\ feet

Thus, 24 square feet of mulch he will need for the flowerbed.

The slope of the line below is 1.write the point-slope equation for the line using the coordinates of the labeled point.
Oliga [24]

Answer:

y-4=(x-11) or y=(x-11)+4

Step-by-step explanation:

We know that the slope of the line is 1, so we can write it in terms of any two points belonging to the line, as per the difinition of slope:

slope=\frac{y_1-y_0}{x_1-x_0} \\1=\frac{y_1-y_0}{x_1-x_0}

We can use instead of (x_1,y_1) any general point (x,y) on the line, and for (x_0,y_0) the point we are interested in: (11,4)

That way the slope can be written as:

1=\frac{y-4}{x-11}

Next we can solve for y if this format is the one your instructor prefers:

1=\frac{y-4}{x-11}\\1(x-11)=(y-4)\\(x-11)+4 =y

Is it possible to have a regular polygon with measure of each exterior angle as 58° ? Why ?​
ehidna [41]
Поскольку правильный многоугольник не может делить сторону, невозможно получить правильный многоугольник с внешним углом = 58 градусов. Однако возможен неправильный многоугольник с одним или двумя внешними углами = 58 градусов.
