Answer:

A) 13:8

b) 8:5

Step-by-step explanation:

In this question, we will be making ratios.

Ratios are represented as a:b whereas "a" and "b" represent the different scenarios.

In this question, we need to make ratio with total apples and red apples.

We will write the ratio in respective order, or from left to right in the statement.

We know that our total amount of apples is 13, so that would go on the left side of the ratio.

We need to find the amount of red apples in the basket. We already have 5 green apples, so subtract 5 from 13.

13 - 5 = 8

We have 8 red apples, so that would go on the right side of the ratio.

Your ratio should be:

13:8

In this question, we have to make a ratio of red apples to green apples.

We know that there are 8 red apples, we also know that there's 5 green apples.

With this information, we can make our ratio:

8:5

Answer:

The length of the other leg of the triangle is 30 inches.

Step-by-step explanation:

Pythagorean: a^2+b^2=c^2

50=hypotenuse

50^2-40^2=missing leg

50^2=2500

40^2=1600

50^2-40^2=900

[tex]\sqrt{900}[/tex]=30

30 is missing leg

The length of the other leg of the triangle is; 30 inches.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We have been given that the length of the hypotenuse of a certain right triangle is 50 inches and the length of its legs is 40 inches.

Using Pythagorean:

[tex]a^2+b^2=c^2[/tex]

50 = hypotenuse

Let the missing length is x.

x² = 50^2-40^2

x² = 2500 - 1600

x²  = 900

x =30

Hence, the length in inches of the other leg of the triangle is 30.

Step-by-step explanation:

3y + x = 12

When y = 3, we have 3(3) + x = 12.

=> 9 + x = 12, x = 3.

Answer:

Average rate of change for given function is: -2

Step-by-step explanation:

Given function is:

[tex]f(x)=x^2-6x+8\\x_12= 1\\x_1 = 3[/tex]

In order to find the rate of change, we have to find the value of function on x1 and x2

So,

[tex]f(x_1) = (3)^2-6(3)+8 = 9-18+8 = -1\\f(x_2) = (1)^2-6(1)+8 = 1-6+8 = 3[/tex]

The formula for finding the rate of change is:

[tex]Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

Putting the values, we get

[tex]=\frac{3-(-1)}{1-3}\\=\frac{3+1}{-2}\\=\frac{4}{-2}\\= -2[/tex]

Hence,

Average rate of change for given function is: -2

Answer:

Step-by-step explanation:

When you have a wording that matches ...

  A depends on B

It means that A is the dependent variable, and B is the independent variable.

Here, the total monthly cost depends on the number of cups purchased.

That statement tells you that "total monthly cost" is the dependent variable, and "number of cups purchased" is the independent variable (x).

The first four (4) blanks you're to fill represent two different ways of saying this same thing.

__

The equation is a mathematical expression of the way the costs add up.

  total monthly cost = (program cost) + (per-cup cost) × (number of cups)

  M(x) = 15 + 2x

Then M(13) is ...

  M(13) = 15 + 2·13 = 15 +26 = 41

So the total monthly cost for the purchase of 13 cups of coffee is $41.

Given:

A line passes through the origin and the point (-2,1).

To find:

The slope of the line.

Solution:

If a line passes though two point, then the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that a line passes through the origin, .i.e., (0,0) and the point (-2,1). So, the slope of the line is

[tex]m=\dfrac{1-0}{-2-0}[/tex]

[tex]m=\dfrac{1}{-2}[/tex]

[tex]m=-\dfrac{1}{2}[/tex]

Therefore, the slope of the line is [tex]-\dfrac{1}{2}[/tex].

Answer: 29

Step-by-step explanation:

Let the smaller number be x

Let the bigger number be x+2

The information given in the question can be represented in a equation as:

x + 2 + 2x = 4x - 27

3x + 2 = 4x - 27

4x - 3x = 27 + 2

x = 29

The smaller number is 29
