Answer:

= 12 miles per hour

Step-by-step explanation:

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=

In a​ company, ​95% of the workers are men. If 125 people work for the company who​ aren't men ​, how many workers are there in​ all? Use pencil and paper. Show two different ways that you can solve this problem.


ill give you brainliesttttt

Answers

Based on the percentage of men workers in the company, the total number of workers is 2,500.

What is the percentage?

The percentage is the fractional value of a variable concerning another.

Percentages are like ratios and proportions, which show the numerical relationship between the independent and dependent variables.

The percentage of men workers = 95%

The number of non-men workers = 125

The percentage of non-men workers = 5% (1 - 95%)

If 5% of the workers are 125, the total number of workers, 100% = 2,500 (125/5% x 100%).

Check:

Men workers = 95% = 2,375

Non-men workers = 5% = 125

Total = 2,500

Thus, given the percentage of men workers as 95%, the total number of workers in the company is 2,500.

The total number of workers in the company is 2,500.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

In a​ company, ​95% of the workers are men.

125 people work for the company who​ aren't men.

We need to find number of workers working in the company.

The percentage of men workers = 95%

The number of non-men workers = 125

The percentage of non-men workers = 5% (1 - 95%)

Men workers = 95% = 2,375

Non-men workers = 5% = 125

If 5% of the workers are 125

the total number of workers, 100% = 2,500 (125/5% x 100%).

Total = 2,500

Thus, given the percentage of men workers as 95%, the total number of workers in the company is 2,500.

Hence the total number of workers in the company is 2,500.

What is the value of both these problems?

Answers

The first one will be 71 as the answer. The second one 62 as an answer

Problem 2

We have an isosceles triangle because of the two congruent sides (21 each).

The angles opposite the congruent sides are known as the base angles, and the base angles are congruent. For now, we don't know what they are. They are both x. I recommend writing 'x' onto the diagram where that missing unmarked angle is.

Then we'll use the idea that all three angles of any triangle always add to 180

x+x+38 = 180

2x+38 = 180

2x = 180-38

2x = 142

x = 142/2

x = 71

Answer: Choice A) 71

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

Problem 3

We use the same ideas as the previous problem. This time the base angles are 56 degrees each. The remaining angle is x.

x+56+56 = 180

x+112 = 180

x = 180-112

x = 68

Answer: Choice A) 68

A wire 45 meters long is cut into two pieces, One piece is 5 meters longer than the other. What is the length of the two pieces? Create an equation and solve .

Answers

Given:

A wire 45 meters long is cut into two pieces

One piece is 5 meters longer than the other.

To find:

The length of the two pieces.

Solution:

Let length of one piece be x.

One piece is 5 meters longer than the other. So,

Length of another piece = x+5

Total length of wire is 45. So,

[tex]x+(x+5)=45[/tex]

[tex]2x+5=45[/tex]

Subtract 5 from both sides.

[tex]2x=45-5[/tex]

[tex]2x=40[/tex]

Divide both sides by 2.

[tex]x=\dfrac{40}{2}[/tex]

[tex]x=20[/tex]

Now,

Length of one piece = 20 meters

Length of another piece = 20 + 5

                                        = 25 meters

Therefore, the length of two pieces are 20 and 25 meters.

Write the standard form of the equation of a line with a slope of -4 passing through the point (1, -4).

Select one:
a. -4x - y = 0
b. -x - 4y - 15 = 0
c. x + 4y + 15 = 0
d. 4x + y = 0

Answers

I think the answer is a.

Answer:

Step 1: We must determine the equation of the line in slope-intercept form* by solving for b.

[tex]-4 = -4(1) + b\\\\-4 = -4 + b\\\\0 = b[/tex]

Step 2: Now we write the equation in slope-intercept form.

[tex]y = -4x[/tex]

Step 3: We can now change the above equation to standard form by moving variables to one side.

[tex]y = -4x\\\\4x + y = 0[/tex]

Our answer is D. 4x + y = 0.

*Slope-intercept form: y = mx + b.

Find an equation for the line below in y=mx+b

Answers

Answer:

y = -1/2x - 11/2

Step-by-step explanation:

Using slope intercept form y = mx + b, to determine the equation, first count the rise(vertical or change in y), and run(horizontal or change in x) of the line.

m is the slope, b is the y-intercept which will remain when x is 0 as this will cancel out the m.

Be careful when determining the slope, and pay attention to the steps(count) of the x, and y axis.

As this graph measures a line with a negative slope passing through the y axis at -5 1/2 → -11/2, with a step of 1, we can count the squares normally to determine the slope.

So since we know that this line has two obvious points (-5,-3) and (1,-6) we can use the equation for slope to measure it's steepness.

m = y2-y1/x2-x1

with (x1,y1) being the first point, and (x2,y2) being the second point.

So: (negative minus a negative makes a positive)

m = -6-(-3)/1-(-5) = -6 + 3/ 1 + 5 = -3/6 = -1/2.

Since m = -1/2, and b = -11/2, the line must be y = -1/2x - 11/2.

Given ΔDEF : ΔRST, find x. 12 15 16 64

Answers

Answer:

12

Step-by-step explanation:

For ΔDEF similar to ΔRST, the value of x is 12. So, option a) is correct.

Two triangles are said to be similar if corresponding angles are equal or  corresponding sides are in the same proportion.

Given triangles are similar:

ΔDEF ~ ΔRST

Therefore, using the property of similar triangle that corresponding sides of a similar triangle are in same proportion.

[tex]\dfrac{EF}{ST}=\dfrac{ED}{SR}\\\\\dfrac{x}{16}=\dfrac{3}{4}\\\\x=\dfrac{3}{4}\times 16\\\\x=12[/tex]

Thus, the value of x is 12. So, option a) is correct.

Use the formula rise/run. But first, if you plot this on a graph, (-1,4) will come first because its x value is smaller. So, for this, let's look at (-1,4) first.

To get from -1 to 3, you must rise 4 units. To get from 4 to 7, you must run 3 units.

So, if you put this together, you will get 4/3!
