Answer:

#1 Is 7 Students

#2 Is 9 Students

#3 Is 16 Students

#4 is 125 tables

Answer:

3

Step-by-step explanation:

"Rate of change" is the real-world problem way of saying "slope."

So whenever a question asks you to find "rate of change", simply look for the slope.

y = mx + b

e = 3h + 200

mx = slope/rate of change

So, 3 would be your answer.

Answer: 33% or 3/9 probability of getting a red marble

Step-by-step explanation:

In total there are 9 marbles

1+2+3+3=9

3 of those are red marbles so it's 3/9

Answer:

Small flags = 108

large flags= 47

Step-by-step explanation:

Step one:

given

let the number of small lag be x

and big flags be y

so

3.5x+6.5y= 683.5----------1

x+y=155------------------------2

Step two:

from eqn 2 x= 155-y

put x= 155-y in  eqn 1

3.5(155-y)+6.5y= 683.5

542.5-3.5y+6.5y=683.5

collect like terms

3y=141

divide by 3

y= 141/3

y=47

Step three:

put y= 47 in eqn 2

x+47=155

x= 155-47

x=108

Answer:

The slop is 1 and the y intecept is 2

Step-by-step explanation:

Answer:

Slope=3

Y intercept=2

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

[tex]\frac{2}{3} = \frac{x}{12}[/tex]

Now isolate x (in order to solve for it)

[tex]12 * \frac{2}{3} = \frac{x}{12}*12\\8 = x[/tex]

x= 8

The height is 8.

8/12 = 2/3 ✅

Which TWO expressions are equivalent to (x - y) 2/3 - 3/4 (y-x)

Answer:

he did nothing wrong

Step-by-step explanation:

Given :

A 13ft ladder is leaning against a wall when its base starts ti slide away from the wall.

By the time its base is 12 feet from the wall, the base is moving at the rate of 5ft/sec.

To Find :

How fast is the top of the ladder sliding down the wall.

Solution :

By, Pythagoras theorem, distance of ladder from horizontal to wall is 5 feet.

Now, [tex]x^2 + y^2 = 13^2[/tex]

Differentiating both sides, we get :

[tex]2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}=0\\\\(2\times 12\times 5) + (2\times 5 \times \dfrac{dy}{dt})=0\\\\\dfrac{dy}{dt}= -12 \ feet/sec[/tex]

Step-by-step explanation:

Alright, archtan /

tan

−

1

(

x

)

is the inverse of tangent. Tan is

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

Answer:

C.-9, -1, -3,5

Step-by-step explanation:

Given

y = 2x - 3 ---- [missing equation]

Required

Complete the table

To do this, we simply substitute the values of x in the given equation.

When x = -3

y = 2 * -3 - 3

y = -6 - 3

y = -9

When x = 1

y = 2 * 1 - 3

y = 2 - 3

y = -1

When x = 0

y = 2 * 0 - 3

y = 0 - 3

y = -3

When x = 4

x = 2 * 4 - 3

y = 8 - 3

y = 5

Hence, the missing gap can be filled with: C.-9, -1, -3,5

Answer:

TRUE

Step-by-step explanation:

Answer:

THE ANSWER IS TRUE

Answer:

a=(z-2)/2

Step-by-step explanation:

You need to isolate your "a" variable so first you want to subtract 2 from both sides, leaving you with:

z-2=2a

then you want to divide by 2 on both sides to isolate your "a" variable which would leave you with

a=[tex]\frac{(z-2)}{2}[/tex]
