Can you please fill in this table?
ELEN [110]

Answer:

Middle School In Favor: 25%

Middle School Not in Favor: 75%

High School In Favor 20%

High School Not In Favor 80%

Step-by-step explanation:

For the middle school in favor, we need to find the percent, which is 50 out of 200, so its 1/4, 25%

So the rest of the middle school is not in favor, which is 75%

High school is 60 not in favor, so we need to find the percentage. So 60 out is 300 is 20%

And we just subtract 20 from 100 which leaves us with 80

Can some one please help me with these five questions
valina [46]

Answer:

1)PT = 21 units

2)Option D

3)Option A

4)∠EFG = 2(24) +15 = 63 degrees

∠GFH= 4(24) +21 = 117 degrees

5) circumference = 21.98 cm

Step-by-step explanation:

1) As the T is midpoint, PT is equal to TQ in magnitude.

  Thus, 4x+1=6x-9

 2x = 10

x=5.

Thus, PT = 4(5) + 1 = 21

2) The planes XTS and VRS intersect in the line SW, and the intersection is perpendicular.

3)For a line to be defined, it must have 2 points, start and end.

  The option A) is not defined properly, so incorrect

4)As the angles are linear pair, their sum is 180 degrees.

Thus, 2n+15+4n+21 = 180

6n = 144

n = \frac{144}{6} = 24

∠EFG = 2(24) +15 = 63 degrees

∠GFH= 4(24) +21 = 117 degrees

5) diameter = 7 cm

radius = 3.5 cm

circumference = 2\pi R = 2\pi (3.5) = 2(3.14)(3.5) = 21.98 cm

What is the distance from the dance hall (-2,2) to the university (0,2)
Anna [14]

Remember the formula for the distance formula:

D = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}

where (x_1, y_1) and (x_2, y_2) are coordinates


Given this formula, we can simply insert our points into the formula:

D = \sqrt{(2 - 2)^2 + (0 - (-2))^2}

D = \sqrt{(2)^2}

D = 2


The distance is 2 units long.
