Answer:

There are 12 students per 1 teacher.

Step-by-step explanation:

To find the unit rate you divide 72/6

if 500 students were at the assembly, then the number of students who were wearing spirit wear is 200 students.

Since we know that:

4/10 of every student is wearing spirit wear.

The total number of students was 500

Hence,

We can express this as:

4/10 x 500

=4 x 50

= 200

Answer:

height = 8/3

Step-by-step explanation

I'm assuming that this is a question to a triangle. So since an area of a triangle is 12 you solve by the formula 1/2(base)(height). You would solve for height so your equation would look smth like this: 12 = 1/2(base)(height). So you would end up with 24/8 which would simplify to 8/3.

Answer:

x= 4 2/3 OR 14/3 OR 4.6... –– 4 2/3 and 4.6... are the simplest form.

Step-by-step explanation:

Your original equation is -192 = -6 (6x - 4):

1. -192 = -6 (6x - 4)

Use distributive property and multiply: -6 x 6x = -36x and -6 x -4 = 24:

2. -192 = -36x + 24

We now move the +24 onto the other side of the equation, -192. Add 24 onto -192 and since we're moving the 24 on the left side of the equation, 24 will removed, so -24 on the right side of the equation:

3. -192 + 24 = -36x + 24 - 24

Divide both sides of the equations by -36 to get "x" by itself:

4. -168 / -36 = -36x / -36

Simplify the fraction of 24/36 by 12:

5. 4 24/36 = 4 2/3 or 14/3 or 4.6... = x

4 2/3, 14/3, 4.6... = x

Answer:

18°

Step-by-step explanation:

let the angle be x , then its complement is 90 - x

we are told the angle is [tex]\frac{1}{4}[/tex] of its complement , then

x = [tex]\frac{1}{4}[/tex] (90 - x) ← multiply both sides by 4 to clear the fraction

4x = 90 - x ( add x to both sides )

5x = 90 ( divide both sides by 5 )

x = 18

then the angle is 18° and its complement is 90° - 18° = 72°

Answer:

The angles measure 18° and 72°.

Step-by-step explanation:

81 and 9 is not correct for this problem.

9 is not 1/4 of 81, so 9 and 81 cannot be the answer, although it is true that angles measuring 9° and 81° are complementary since 9 + 81 = 90.

You need to know what complementary angles are.

Definition:

Two angles are complementary if the sum of their measures is 90°.

Each angle is said to be the complement of the other angle.

You have two complementary angles, both of whose measures are unknown.

Call the smaller measure x and the larger measure y.

Since the angles are complementary, the sum of their measures is 90°.

x + y = 90

The measure of one angle is 1/4 the measure of the other angle.

If the smaller angle's measure is 1/4 of the larger angle's measure, then the larger angle's measure is 4 times the smaller angle's measure.

That means that y = 4x.

You have two equations and two unknowns:

x + y = 90

y = 4x

This is a system of equations. We will solve it using the substitution method.

Since y = 4x, where you see y in the first equation, substitute it with 4x

x + y = 90

x + 4x = 90

5x = 90

Divide both sides by 5.

x = 18   <---- smaller angle

y = 4x = 4(18) = 72   <----- larger angle

Answer: The angles measure 18° and 72°.

Check: Do the measures 18 and 72 add to 90?

18 + 72 = 90    Yes.

Is the measure of the smaller angle 1/4 the measure of the larger angle?

18/72 = 9/36 = 1/4    Yes.

18 and 72 is the correct answer.

Answer:

No, because each sample of 100 does not have the same chance of being selected.

Step-by-step explanation:

Simple random samples require that every possible sample of the population has an equal chance of being selected. Because of the fact that certain ages are being picked at certain amounts, not every possible sample has the same chance of being selected, so this is not an SRS.

Answer:

Step-by-step explanation:

Equation of line k is   y = (-4/7)x + 1

point (-5,-10); m = -4/7

Line L is perpendicular to k so the perpendicular slope will be 7/4

Equation of line L is  (y - y1) = m(x-x1)

y+10 = (7/4) (x +5)

4y + 40 = 7x + 35

4y = 7x - 5

y = (7/4)x - (5/4)

Answer:

x=-2

Step-by-step explanation:

just plug in random numbers until you get your answer, it works for me

Equations are steeper when their slope's positive value is higher (ignore negatives when determining how steep a slope is). The slope is the value in front of x. If there isn't a value in front of x, then it is assumed to be 1.
