what is 0.0042 as a fraction in simplest form

Answers

Answer:

21/5000

Step-by-step explanation:

0.0042 takes the form of 21/5000 as a fraction.

Answer:

21/500

Step-by-step explanation:

0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)

42 is an even number so, divide by 2 to simplify.

42/2 = 21 and 1000/2 = 500

21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.

80%

Answers

Answer:

80%

Step-by-step explanation:

There are 4 shaded sections and 1 unshaded section, so five sections in total.

4 sections are shaded, so the fraction would be 4/5.

Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).

Answer:

D. 80%

Step-by-step explanation:

A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.

Answers

The slope is 0.75 as 3/4 = 0.75

Answer:

Step-by-step explanation:

Only the blue line has a positive slope.  So the new line is parallel to the blue line.

Clearly, the blue line goes through the point (0, 3) (this is the y-intercept).  Follow this blue line upward and to the right until it intersects the horizontal line at the top of the diagram.  We must estimate the x-value of this point of intersection.  A good approximation would be 5 1/3.

Now estimate the slope of the blue line.  Starting at (0, 3), we move 5 1/3 units to the right (this is the "change in x," or "run")  We end up at (5 1/3, 3).  

Now, from the horizontal line y = 3 upward to the horizontal line at the very top of the graph, is 5 units.  This is the "rise."

Thus, the approximate value of the slope here is

                              5               5             15

m = rise / run = ---------- = -------------- = ----------- = m

Sanjay consulted three electricians about upgrading the wiring in his home. Each electrician uses a linear formula that incorporates a flat base fee and an hourly rate to determine the cost of service. Those formulas are shown in the table.

Repair Cost Formulas
Electrician
Cost in y dollars for an x-hour service
1
y = 25 x + 30
2
y = 30 x + 25
3
y = 25 x + 20

Which statement is best supported by the table?
Each electrician charges a different hourly rate.
Each electrician charges a different base fee.
All three electricians charge the same hourly rate.
All three electricians charge the same base fee.

Answers

Answer: B: each electrician charges a different base fee

Step-by-step explanation:

Answer:

b.Each electrician charges a different base fee:

Explanation:

Each of the equations has two parts:

1- base fee that is independent of any variable (this would be the number that has no variable next to it)

2- an hourly rate depending on the number of hours x (this would be the number that has an x next to it)

For the first electrician:

y = 25x + 30

base fee = $30

hourly rate = $25

For the second electrician:

y = 30x + 25

base fee = $25

hourly rate = $30

For the third electrician:

y = 25x + 20

base fee = $20

hourly rate = $25

Now, let's check the choices:

a.Each electrician charges a different hourly rate:

This is incorrect as electricians 1 and 3 charge the same hourly rate ($25)

b.Each electrician charges a different base fee:

This is correct as all three base fees are different ($30, $20 and $25)

c.All three electricians charge the same hourly rate:

This is incorrect as electrician 2 has a different hourly rate

d. All three electricians charge the same base fee:

This is incorrect as the base fees for the three electricians are different ($30, $25 and $20)

The ratio is 2in to 8mm
so safe to assume 1in represents 4mm.
1in = 4mm

The equation to find the length is:
1.5in = x mm
if we know that 1in is 4mm, 0.5in is 2 mm. So the answer is:
1.5in = 6mm.

The equation to find the width is:
0.75in = x mm
0.75 is 3/4, and 1in = 4mm, so 3/4 of 4 is 3. Therefore,
0.75in = 3 mm

Finally, the answer is:
Length = 6mm
Width = 3mm

this is all first in expanded form then standard form

Consider the equation y = 1.5x + 2. Find four pairs of x and y values that make
the equation true. Plot the points (x, y) on the coordinate plane.
Based on the graph, can this be a proportional relationship? Why or why not?

Answers

Answer:

1. (2,5),(1,3.5),(4,8),(6,11)

2. This is not a proportional relationship (explanation below)

Step-by-step explanation:

For the plotting, if you take some random x values and multiply by 1.5 and add 2 to them.  

This can't be a proportional relationship. A proportional relationship means the x and y values' ratios have to stay the same. However, because 2 is added to 1.5x, the equation is not proportional.

The four x and y values that make the equation true are (0,2), (-1.333,0), (1,3.5), and (1,3.5).

What in mathematics is a proportionate relationship?When the ratios of two variables are equal, they form proportional relationships. Another way to think about them is that in a proportionate relationship, one variable is always equal to the constant value of the other.This constant is known as the "constant of proportionality." To find: The four sets of x and y values required to solve the equation. Put the (x, y) coordinates on a coordinate plane.

Therefore,

We select several x and y values,

1) Take x=0,

y = 1.5(0) + 2 =2.

The point is (0,2).

2) Take y=0,

0 = 1.5x + 2

x = -2/1.5 = -1.333

The point is (-1.333,0).

3) Take x=1,

y = 1.5(1) + 2 = 3.5

The point is (1,3.5).

4) Take y=1,

1 = 1.5x +2

1.5x = -1

x = -1/1.5 = -0.666.

The point is (-0.666,1).

The four sets of x and y numbers that make the equation true are (0,2), (-1.333,0), (1,3.5), and (0,2).
