Answer:

B. 5

Step-by-step explanation:

$40/$8 = 5

Answer : 5

Step-by-step  multiply 8 times 5

Answer:

80 is the answer

Step-by-step explanation:

The direct variation is given by:

[tex]F=k\,\frac{m}{d^2}[/tex]

So given the values for each variable, we can find the constant of proportionality k:

[tex]F=k\,\frac{m}{d^2} \\60=k\,\frac{1470}{7^2} \\k = \frac{60*49}{1470} \\k=2[/tex]

Then we can now find what the value is when m = 2560 and d = 8 by using the proportionality equation with k = 2:

[tex]F=2\,\frac{m}{d^2} \\F=2\,\frac{2560}{8^2}\\F=80[/tex]

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

n  =  8

Step-by-step explanation:

Have a nice day! I hope this helps!

Answer: n=8

Step-by-step explanation:Step 1: Simplify both sides of the equation.

17n−23n+11.5n=44

17n+−23n+11.5n=44

(17n+−23n+11.5n)=44(Combine Like Terms)

5.5n=44

5.5n=44

Step 2: Divide both sides by 5.5.

5.5n/5.5=44/5.5

Answer:

0.375mL/polyethylene

Step-by-step explanation:

Total number of plastic bags = 24 plastic bags

amount of polyethylene created = 9mL

This means that;

24 plastic bags = 9mL of polyethylene

1 plastic bags = x

Cross multiply

24 * x = 9 * 1

24x = 9

x = 9/24

x = 0.375mL/polyethylene

Hence the rate of polyethylene used per plastic bag is 0.375mL/polyethylene

Answer:

Answer:

It is D

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

As you can see all the points are on the line except for C

The ordered pairs is a solution to the equation are: (1, 2) and (2, 4) thus the point C is not a solution.

An equation is an expression that shows the relationship between two or more numbers and variables.

We have to find the ordered pair of a solution to the equation:

Equation is y = 2x

For ordered pairs: (1, y)

y = 2x

y = 2

For Pair (2, y)

y = 2 (2)

y= 4

Hence, The ordered pairs is a solution to the equation are: (1, 2) and (2, 4)

Answer:

78.5  sq.ft

Step-by-step explanation:

3.14*5*5

78.5 sq. ft

Answer:

25π ft^2

Step-by-step explanation:

The equasion to solve for area is, A=πr^2

so if the radius is 5 you would put that in r. A=π5^2, so next because of pemdas you would solve five to the power of 2 which is 25. so you answer is A=25π

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

Explanation:

Note the angles of triangle URT are all the same due to the similar arc markings. Each angle of this triangle is 60 degrees because 60+60+60 = 180.

Since angle URT is 60 degrees, this makes angle TRS to be 180-60 = 120 degrees. Angles URT and TRS are supplementary, meaning they add to a straight angle of 180 degrees.

Focus on triangle TRS. We have the top angle equal to 120 we found earlier. The two bottom base angles are both equal to 3y. We know they're equal because of the arc markings they share.

Triangle TRS has the angles of 120, 3y and 3y. Add these angles up, set the sum equal to 180 and solve for y

120+3y+3y = 180

120+6y = 180

6y = 180-120

6y = 60

y = 60/6

y = 10

So that takes care of the value of y.

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

Now to find the value of x.

Triangle TRS is isosceles because of the congruent base angles. The sides opposite these congruent base angles are side TR and side RS. We can say TR = RS for short.

Because RS = 15, we know that TR = 15 as well

Now move to triangle URT. This is an equilateral triangle. All equilateral triangles have interior angles of 60 degrees each.

By definition of what it means to be equilateral, we know that UT = TR

So UT = 15

Let's solve for x

UT = 15

x-5 = 15

x = 15+5

x = 20

Answer:

The average rate of change of the given function

A(x) =  1

Step-by-step explanation:

Step(i):-

Given function f(x) = x² - 2x -4

And given that x = a = -1 and  x=b = 4

The average rate of change of the given function

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

Step(ii):-

f(x) = x² - 2x -4

f(-1) = (-1)² - 2(-1) -4 = 1+2-4 = -1

f(4) = 4² -2(4) -4 = 16 -12 = 4

The average rate of change of the given function

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

[tex]A(x) = \frac{4-(-1)}{4-(-1)} = \frac{5}{5} = 1[/tex]

final answer:-

The average rate of change of the given function

A(x) =  1

Answer:

A(x) = 1

Step-by-step explanation:

[tex]f(-1) = (-1)^{2} -2(-1)-4 == -1\\f(4) = (4)^{2} -2(4)-4 == 4[/tex]

When we plug this into the formula for rate of change we end up with...

[tex]\frac{f(4)-f(-1)}{4-(-1)} \\= \frac{4-(-1)}{4+1} \\= \frac{5}{5}\\= 1[/tex]
