all you really need to do is find the common denominator and it'll get you an answer for the numerator.

Answer:

13/15

Step-by-step explanation:

You first need to find the common denominator between both 3 and 5, so you have to find the number that would be the best, which is 15. Then you have to multiply the numerator by how many times you went up for that number, for 2/3 would be times 5, and 1/5 would be times 3. Doing this will get you your answer, 13/15.

The bicycle wheel revolving is a illustration of circumference

The bicycle wheel revolves 4000 times

The given parameters are:

Radius (r) = 40 cm

Distance =10 km

Start by calculating the circumference of the wheel

[tex]C =2\pi r[/tex]

This gives

[tex]C =2 * 3.142 * 40[/tex]

[tex]C =251.36[/tex]

The number of times to cover a distance of 10 km is then calculated as:

[tex]n =\frac{10km}{251.36cm}[/tex]

Evaluate the quotient

[tex]n =3978.35773[/tex]

Approximate

[tex]n =4000[/tex]

Hence, the bicycle wheel revolves 4000 times

Step-by-step explanation:

Answer: T

Step-by-step explanation:

By the alternate interior angles theorem, the given statement is true.

The ratio p:9 is equal to 50:9 = [tex]\frac{50}{9}[/tex].

System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.

For solving this equation, firstly, rewrite the information given:

                                          [tex]\frac{p-5}{q-5}=\frac{9}{1} \;(1)\\ \\\frac{p+20}{q+20}=\frac{7}{3} \;(2)[/tex]

From equation 1, you have:

                                        [tex]p-5=9q-45\\ \\ p=9q-40[/tex]

And from equation 2, you have:

                                  [tex]3*(p+20)=7*(q+20)\\ \\ 3p+60=7q+140\\ \\[/tex]

Now, substitute p=9q-40 in 3p+60=7q+140

                                 [tex]3p+60=7q+140\\ \\3*(9q-40)=7q+140\\ \\ 27q-120=7q+140\\ \\ 20q=20\\ \\ q=10[/tex]

If q=10 for p=9q-40,  you will have:

                                [tex]p=9q-40\\ \\ p=9*10-40\\ \\ p=90-40\\ \\ p=50[/tex]

Therefore, the ratio  [tex]\frac{p}{9}[/tex]  is equal to [tex]\frac{50}{9}[/tex].

Second Equation: Infinite Solutions

Third Equation: One Solution

Step-by-step explanation:

Let's solve these equations step by step.

[tex]-2x+3=-3x+2\\[/tex]

Subtract 2 and add 2x

[tex]1=-x\\x=-1[/tex]

The only solution here is -1.

[tex]-2x+3=-2x+3[/tex]

Anytime the equations are the same on both sides, we have infinite solutions.

Add 2x

Step-by-step explanation:

Its continous because after each day you take the same  amount away and due to that it will be continous.

A line that is perpendicular to a line with slope m has slope -1/m which is the opposite reciprocal of the original slope.

In this case the original line in standard form is

2x-4y=-8

transform this into slop intercept form

-4y=-2x-8

4y=2x+8

y=(1/2)x+2

The slope of this original line is 1/2 therefore the perpendicular line will have slope -2

y'=2x'+b

then substitute in the order pair (x',y')

1=2(-2)+b

b=5

Therefore equation of line is

y=2x+5

The graph is just following this equation!
