Answer:

220

Step-by-step explanation:

11 classes total   11 multiplied by 20=220

Answer:220

Step-by-step explanation:

20*5=100

20*6=120

120+100=220

Answer:

23. y = 47

Step-by-step explanation:

40 + 5x =180 (angls on a straight line add up to 180 degrees)

5x=140 (minus 40 from both sides)

x = 28 (divide both sides by 5)

3y - 1 = 140

3y =141 (add 1 to both sides)

y = 47 (divide both sides by 3)

Answer:

y=47

Answer:

its the last one

Step-by-step explanation:

so first you gotta add up all the animals in the zoo

2+4+3+6 which equals 15

then you gotta see how many goats there are there are 6 goats

so 6/15 are goats

U CAN REDUCE

so what number can divide into 6 and 15 evenly? 3!!!!!

so u divide 6 by 3 to get 2

then u divide 15 by 3 to get 5

NOW U GOT THE ANSWER 2/5

Answer:

Step-by-step explanation:

Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept

1. Points are:

Slope is:

y-intercept is - 6 as per graph

Then the formula is

2. Points are:

Slope is:

y-intercept is 5 as per point

Then the formula is

3. Points are:

Slope is

y-intercept is -5 as per graph

Then the formula is

Answer:

45

Step-by-step explanation:

Answer:

$46.20

Step-by-step explanation:

Since it was discounted 30%, this means that 30% of the original price was taken off. To find the price remaining after the discount, you subtract 30% from 100% which would give you 70%. Then multiply $66.00 and 0.7 and you will get $46.20

Answer:

im pretty sure its all of them

Answer:

option 2 Nd 3 only my friend.

Answer:

what's the whole question

Step-by-step explanation:

Answer:

the correct answer is ten

Answer:

4.5 as a mixed number is 4 1/2

4.5 as an improper fraction is 9/2

equal on all sides. so it can be any number on all sides as long as they're the same

Answer:

The correct option is;

20-gon

Step-by-step explanation:

The area, A, of a regular polygon is given as follows;

[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]

Where;

n = The number of sides

s = The length of one side of the polygon

a = The apothem

[tex]P_p[/tex] = The perimeter of the polygon

Where

The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r

Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.

Answer: 33.3_

Step-by-step explanation:

400 divided by 56 equals 17.14_ and 17.4_ multiplied by 14 equals 100 and divided by 3 is equal to 33.3_

Answer: 0.0425

Step-by-step explanation:

PEMDAS

1. 56x14

2. 400/784

3. 0.1275/3

4. 0.0425

In a rhombus, both pairs of opposite angles are congruent

so m<4=32 degrees

so your answer is 32 DEGREES

Answer:

  y = 9x -3

Step-by-step explanation:

The given line is in "slope-intercept form"

  y = mx + b

where m is the slope and b is the y-intercept (where it crosses the y-axis).

In your given line, we have ...

  m = 9, b = 4

__

A parallel line will have the same slope, so we know that the line you want has m = 9. You are told to make the line cross the y-axis at -3, so that makes b = -3. Putting these values into the slope-intercept form gives the desired equation:

  y = 9x -3

_____

The attached graph is intended to show the lines are parallel and the equation given here meets the requirement for a crossing of the y-axis at -3. The vertical and horizontal scales are different in order to better show these things.

Answer:

[tex]m=8[/tex]

Step-by-step explanation:

Step-by-step explanation:

Answer:

[tex]- \frac{2 }{3} [/tex]

Step-by-step explanation:

[tex]the \: slope : m = \frac{3 - 5}{8 - 3} = \frac{ - 2}{ + 5} = - \frac{2 }{3} [/tex]

♨Rage♨

Answer:

[tex] \frac{9}{2} = \frac{1}{3} hour[/tex]

[tex]x = \frac{3}{3} [/tex]

[tex]x = \frac{ \frac{9}{2} \times \frac{3}{3} }{ \frac{1}{3} } [/tex]

[tex] \frac{27}{6} \times \frac{3}{1} = \frac{27}{2} = 13 \frac{1}{2} [/tex]

Answer:

Step-by-step explanation:

we know that density is given as

density=mass/volume

the volume of the cylinder

v= πr^2h

v=3.142*1.5^2*14.4

v=3.142*2.25*14.4

v=101.8cm^3

Given that density =0.00123g/cm^3

mass= density*volume

masss= 0.00123*101.8

mass= 0.125214 g

Answer:

Quan usually has 4 clients

Step-by-step explanation:

Working backward at math is to start with the final situation and work back one step at a time to get to the beginning.

We know Quan makes $104 a day, including his $72 fixed rate plus an $8 rate per client.

Subtracting the total and the fixed rate, we can find the variable part of his earnings.

$104 - $72 = $32

Quan usually makes $32 for the variable rate at $8 per client, thus he usually has $32 / $8 =4 clients.

Quan usually has 4 clients

Answer:

1, -1, -3, 3

Step-by-step explanation:

f(x) = 2x-1

f(1)=2*1-1 = 2-1 = 1

f(0) = 2*0 - 1 = -1

f(-1) = 2* -1 -1 = -2-1 = -3

f(2) = 2 * 2 -1 = 4-1 =3
