Answer:

2nd first third first 1st last

Step-by-step explanation:

First, add up the two numbers in the ratio => 4+1, which gives us 5.

Now,

4/5×20 => 16

1/5×20 =>4

So, the required answer is 16:4.

Hope it helps!

The solution of dividing 20 in the ratio of 4:1 gives us 16:4.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that the ratio of 4:1

First, we have to add up the two numbers in the ratio

4+1, which gives us 5.

Now,

4/5×20 = 16

1/5×20 = 4

Therefore, the required answer is 16:4.

Answer:

The rate of change of function g is: 3/2

Step-by-step explanation:

Given the table of function g

x               y

2              4

4              7

6             10

8             13

We know that rate of change is also termed as the slope of the function.

Thus,

let us take any two points, let say

(2, 4) and (4, 7)

Determining the slope between (2, 4) and (4, 7)

(x₁, y₁) = (2, 4)

(x₂, y₂) = (4, 7)

Using the formula

Rate of change or Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [7 - 4] / [4 - 2]

               = 3 / 2

Thus, the rate of change of function g is: 3/2

Answer:

the  number of black tokens in the bag is 2

Step-by-step explanation:

The computation of the number of black tokens in the bag is as followS

Given that

There is 8 green tokens

and, the ratio of green tokens to black tokens is 4:1

So let us assume the black tokens be x

So,

[tex]\frac{8}{x} = \frac{4}{1}[/tex]

Now do the cross multiplication

x = 2 tokens

Hence, the  number of black tokens in the bag is 2

Step-by-step explanation:

Hello! :)

Well, the only difference in the two points is from the 0 and the -4. That means the square is 4 units in length and width.

A=B*H=4*4=16 u^2

P=B*4=4*4=16 u

Answer:

A.

Step-by-step explanation:

Answer:

The numbers are 36 and 68.

Step-by-step explanation:

Let the smaller number be x.

"The larger number is four less than two times the smaller

number."

The larger number is

2x - 4

The sum of the numbers is x + 2x - 4, or 3x - 4.

"The sum of the numbers is 104."

3x - 4 = 104

3x = 108

x = 36

The smaller number is 36.

The larger number is 2x - 4, or

2x - 4 = 2(36) - 4 = 72 - 4 = 68

The larger number is 68.

Answer: The numbers are 36 and 68.

Answer:

what arc bro?

Step-by-step explanation:

Answer: 135

Step-by-step explanation:

The two smaller angles are 45, so 45+45= 90 so u subtract 90 from 360. Then u have 270 and u divide tht by 2 and then u have 135 Ans that’s your answer.

the answers are:

b. x = sin -1 (c/b)

c. x = tan -1 (c/a)

e. x = cos -1 (c/b)

Answer:

A) exactly one solution

Step-by-step explanation:

if we set the y values equal we would get

-2x-4 = 3x+3

-7= 5x

x=-7/5

Since we get an x value, the answer is that they have exactly one solution.

Answer:

A van can carry 15 students and a bus can carry 21 students

Step-by-step explanation:

System of Equations

There are separate trips to the water park for which vans and buses were rented. Let's call the variables:

x = number of students that a van can carry

y = number of students that a bus can carry

6 vans and 8 buses were filled with 246 students. This leads to the equation:

6x + 8y = 246

Dividing by 2:

4x + 3y = 123      [1]

4 vans and 8 buses were filled with 228 students. Thus, we form the equation:

4x + 8y = 228     [2]

Subtracting [2] minus [1]:

5y = 228 - 123 = 105

Dividing by 5:

y = 105/5 = 21

y = 21

From [1]:

4x + 3*21 = 123

4x + 63 = 123

Subtracting 63:

4x = 60

Dividing by 4:

x = 60/4 = 15

x = 15

A van can carry 15 students and a bus can carry 21 students

y=-.5x+4
