Unit rate= 20

words per minute/ 0.3

words per second

Step-by-step explanation:

We could work out the unit rate in 2 ways:

Per Minute or Per second.

First we will start of with per minute:

Rate=Word/minute=100/5=20

Answer:

100 words to 5 minutes

Step-by-step explanation:

Answer:

48 inches

Step-by-step explanation:

Remember the Pythagorean theorem, where a and b are legs and c is the hypotenuse

a^2 + b^2 = c^2

a= 20

c = 52

now substitute in the given values

20^2 + b^2 = 52^2

400 + b^2 = 2704

solve using inverse operations

400 + b^2 = 2704

-400            -400

b^2 = 2304

b= sqrt(2304)

b=48

Step-by-step explanation:

Use long multiplication to evaluate.

I'll do the first three problems to get you started

=====================================================

Problem 40

Plug in x = 0 to find the y intercept

x+y = 5

0+y = 5

y = 5 is the y intercept

Plug in y = 0 to find the x intercept

x+y = 5

x+0 = 5

x = 5 is the x intercept

------------

=====================================================

Problem 41

Use the same idea here as well

Plug in x = 0 to get

x-y = 5

0-y = 5

-y = 5

y = -5 is the y intercept

Now plug in y = 0 to solve for x

x-y = 5

x-0 = 5

x = 5 is the x intercept

------------

=====================================================

Problem 42

Plug in x = 0 and solve for y

3x+4y = 12

3(0)+4y = 12

0+4y = 12

4y = 12

y = 12/4

y = 3 is the y intercept

Plug in y = 0 and solve for x

3x+4y = 12

3x+4(0) = 12

3x+0 = 12

3x = 12

x = 12/3

x = 4 is the x intercept

Step-by-step explanation:

Perpendicular Bisector

It's defined as a line that divides another line into two equal parts. The bisector passes through the midpoint of the line forming any angle, but if that angle is exactly 90°, then the bisector is also perpendicular.

We need to find the equation of the line that divides into equal parts the line with endpoints (-1, -2) and (-5,4) and is perpendicular to it.

First, let's find the slope of the line segment. The slope can be calculated with the formula:

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

[tex]\displaystyle m=\frac{4-(-2)}{-5-(-1)}=\frac{6}{-4}=-\frac{3}{2}[/tex]

The line for the perpendicular bisector has a slope m2. Two perpendicular lines with slopes m1 and m2 must comply:

[tex]m_1.m_2=-1[/tex]

Solving for m2:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

[tex]\displaystyle m_2=-\frac{1}{-\frac{3}{2}}=\frac{2}{3}[/tex]

The equation of the perpendicular bisector has the form:

[tex]y=\frac{2}{3}x+b[/tex]

Now we find the coordinates of the midpoint of the segment:

[tex]\displaystyle \bar x=\frac{-1-5}{2}=-3[/tex]

[tex]\displaystyle \bar y=\frac{4-2}{2}=1[/tex]

The midpoint is (-3,1). Using this point will allow us to find the value of b:

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

[tex]b=1+2=3[/tex]

Thus, the equation for the perpendicular bisector is

[tex]\boxed{y=\frac{2}{3}x+3}[/tex]

Answer:

[tex]y = - \frac{1}{2} x[/tex]

Answer:

yes

Step-by-step explanation:

its in y= mx+b form or f(x)= mx+b

Answer:

No, it is a non linear function.

Step-by-step explanation:

As the equation says:

f(x)=5/x+6

Demonstrating 5 in the numerator and x+6 in the denominator it is not a linear function. This is because the x variable is in the denominator which makes it fail to become a linear function. Have a wonderful dayy!!

Answer:

V(t) = 26,000 - 15t

Step-by-step explanation:

Given the following :

Initial approximate volume of water = 26 billion ounces

Yearly consumption = 150 million ounces

Let V = volume remaining

Linear equation to model decreasing supply of water.

Volume left = Initial volume - consumption

Consumption = 150 million per year

Consumption after t years = 150 million * t

Volume left = 26,000,000,000 - 150,000,000t

V = 26,000,000,000 - 150,000,000t

Divide by 1,000,000

V(t) = 26,000 - 15t

Answer:

-21.6

Step-by-step explanation:

When a number, like 4 in your equation, is next to parentheses without a sign (ex. plus or minus) it means to multiply. 4(-5.4) is equal to 4x5.14 which is -21.6

Answer & Step-by-step explanation:

2x + 4 = 2x + 5

To make this equation have infinitely many solutions, you would change the 5 on the right side of the equation to be a 4. This would cause both the expressions to be exactly the same, changing the solution to be infinitely many solutions. You could also change the 4 on the left side of the equation to be a 5.

----------------------------------------------------------------------------------------------------------

To make the equation have only one solution you would change the 2x on the left (or right) side of the equation to be anything other than 2x. For example, you could change the 2x on the right side of the equation to be 3x, making x equivalent to -1, which means that x only has one solution.

Any value that is raised to the power of zero is 1. The value of the expression given in its simplified form is 1

Any value that is raised to the power of zero is 1. Given the expression

(30^2)^0

Simplify

30^2 = 900

Substitute into the original function to have:

(30^2)^0 = 900^0
(30^2)^0 = 1

Hence the value of the expression given in its simplified form is 1

Step-by-step explanation:

Answer:

sand = 3450 pounds

3/4 inch stones =6750 pounds

1 inch stones =4800 pounds.

Step-by-step explanation:

The mixture composition is :

45% three-quarter inch stones

32% inch stones and

sand for balance

The percent here is by mass of material used.

Weight of mixture is 15,000 pounds before oil addition.

Use the percent by weight for the two types of stones and calculate real values in pounds

Formula to apply is:

Mass percent = (mass of a material/ total mass of mixture) * 100

For 3/4 inch stones it will be:

[tex]0.45= \frac{x}{15000} *100\\\\0.45=\frac{x}{150} \\0.45*150=x\\x=6750[/tex]

The 3/4 inch stones weigh 6750 pounds

The 1 inch stones will be

[tex]32/100 * 15000 =4800[/tex]

The 1 inch stones weigh = 4800 pounds

Total for the two items : 4800+6750 =11550 pounds

The sand used weighs : 15000 - 11550 = 3450 pounds

Answer:

There is no fixed domain, meaning it is ongoing

The range is from -1 ≤ x ≤ 3

It is a function

Step-by-step explanation:

Domain refers to the x values. If there was a domain then there would be a dot or a point signalling that there is a fixed domain, however, there are arrows meaning that it will keep going.

The range refers to the y-values. The lowest y-value is -1 and the highest is 3.

It is a function because, when you do the vertical line test, each x-value has its own y-value.
