J=(7x+13) K=(83-2x) and the sum of the measures of the angles is 141. What is the measure of each angle

Answer:

$5.40

Step-by-step explanation:

First, find Dave's purchase. To do this, you multiply 15 by the tax percent and add that to the original.

So:

15 x 8% = 15 x 0.08 = 1.2

15 + 1.2 = 16.2

Next, do the same for Mel's purchase:

20 x 8% = 20 x 0.08 = 1.6

20 + 1.6 = 21.6

Then, you subtract Dave's purchase from Mel's:

21.6 - 16.2 = 5.4

This comes out to $5.40

If Jack finish them all in 5 days, then he can solve m/5 math problem in just one day.

From the given question, jack can only solve m math problems in 5 days, this can be expressed as:

m problems = 5 days

The number of questions he can solve per day is expressed as:

x = 1 day

Take the ratio

m/x = 5/1

5x = m

x = m/5 math problems

Step 1: Find the area of the larger rectangle

Area of a rectangle = base x height

Area = 4 x 3 = 12

Step 2: Find the area of the other rectangle

The tricky part about this one is that we aren't given the length of this rectangle. We do know, however, that the whole base of the figure is 6 and 3 units are taken up by the first rectangle. Therefore, the length of this rectangle is 3.

Area = 2 x 3 = 6

Step 3: Find the area of the figure

Now that we know the area of both rectangles by themselves, all that's left to do is add them up.

6 + 12 = 18

Answer: 18

168 minutes or 2 hours 48 minutes

Step-by-step explanation:

Since 12 tyres is 3 times 4 tyres, it will take 3 times as long as 56 minutes.

3 * 56 minutes = 168 minutes

We can convert the answer to hours and minutes.

60 minutes = 1 hour

120 minutes = 2 hours

168 minutes – 120 minutes = 48 minutes

168 minutes = 2 hours 48 minutes

Answer: 168 minutes or 2 hours 48 minute

Answer:

1,600

Step-by-step explanation:

I did a bit of guessing becuase I don't know the exact way to reverse the formula, but here is what I did!

I guessed around 1,550 at first, but it was too low. I kept increasing the base number until I reached 1,600, and came to the conclusion by doing the equation;

1,600(0.6)=960

Then, since it increases each month by 60% of the previous month's value, you do

1,600+960=2,560

The length of the wire is the perimeter of the wire

The radius of the circle is 1.59 meters

The length of the wire is given as:

L  = 20m

When cut into two pieces, we have:

The circumference of the circle is calculated using:

C = 2πr

So, we have:

2πr = 10

Make r the subject

r = 10/2π

Evaluate the quotient

Step-by-step explanation:

Hi there!

We are given the points  (0, –3) and (4, 5)

We want to find the equation of the line between these points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

To write the equation of the line in this way, we need to first find the slope of the line
The slope can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We already have 2 points, but let's label their values to avoid confusion and mistakes when calculating.

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

m=[tex]\frac{5--3}{4-0}[/tex]

Simplify

m=[tex]\frac{5+3}{4-0}[/tex]

m=[tex]\frac{8}{4}[/tex]

Divide

m=2

We found the slope of the line.

Here is the equation of the line so far:

y=2x+b

Now let's find b

As stated before, b is the y intercept of the line, which is the point where the line passes through the y axis; the value of x at the y intercept is 0

One of the points we were given (0, -3) is actually the y intercept of the line!

The value of b is the value of y at the y intercept; in this case, b is equal to -3

Now substitute -3 as b in the equation.

y=2x-3

By analyzing the data tables given, we will see that:

1) The range is 28.

2) The graph can be seen at the end.

3) There are clusters at 16 and 17, and 25 is an outlier.

4) The range decreases almost by 50%.

The range is defined by the difference between the largest and smallest values from the data set.

So the range is: R = 95 - 67 = 28

The correct option is D.

For each time that a number appears, you need to make a dot above the correspondent value.

The graph can be seen below.

3) we have clusters on 16 and 17, and as you can see, the value 25 is really away of the rest of the values, so we have a gap, and 25 is an outlier.

4) With the 25, the range is:

25 - 16 = 9

If we remove it, the range is:

21 - 16 = 5

So the range decreases almost by a 50%.

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes
