Write an equation representing the relationship of 10:20 shown in the graph
Answers
Answer:
[tex]20=2(10)[/tex]
Step-by-step explanation:
10:20 is a good point that passes a line to another.
This graph is a linear graph.
The linear equation is
[tex]y=mx+b[/tex]
[tex]y[/tex] = 20 (the y coordinate in the graph)
[tex]m[/tex] = slope
[tex]x[/tex] = 10 (the x coordinate in the graph)
[tex]b[/tex] = y-intercept
Finding slope
To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
(10, 20) and (20, 40)
[tex]=\frac{40-20}{20-10}[/tex]
[tex]= \frac{20}{10}[/tex]
[tex]\bold{m= 2}[/tex]
Finding the y-intercept
You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]
(10, 20)
[tex]20=2(10)+b[/tex]
[tex]20=20+b[/tex]
[tex]20-20=20-20+b[/tex]
[tex]\bold{b=0}[/tex]
The y-intercept is zero, and when it is, you do not add it since zero is nothing.
The equation is [tex]20=2(10)[/tex]

HOW DO YOU FIND RADIUS
Answers
Answer:
you can divide the diameter by 2 or divide the circumference by 2pi
Step-by-step explanation:
If the circumference of a circle is given:
Let the radius be r.Say, that the circumference is given as C.By using the formula,[tex]2\pi \: r = C \\ = > r = \frac{C}{2\pi} [/tex]So, to find radius of a circle when circumference is given, we have to divide the circumference with 2π. Then, we will get the radius of the circle.Note : You have to consider π as 22/7 or 3.14. Or the value will be given in the question.If the diameter of a circle is given:
Let the radius be r.Let the diameter be D.By using the formula,2r = D[tex] = > r = \frac{D}{2} [/tex]Hence, if the diameter of a circle is given, we have to just divide the diameter with 2. Then we will get the radius of the circle.Hope you could get an idea from here.

Answer:
29 inches
Step-by-step explanation:
For the following I just used trial and error and experimented with the possibilities:
29 inches - This is the only one that does not work.
30 inches - We can use 5 of the 6 inch trains, so this is possible.
31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.
32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.
33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

Answer:
[tex]7\frac{1}{3}[/tex]
Step-by-step explanation:
So for this problem, we want to solve for x
75x + 50 = 600
First, we isolate x by subtracting 50 from both sides.
75x + 50 - 50 = 600 - 50
75x = 550
Then we divide both sides by 75 to find x
75*x/75=550/75

How many 1/8 tps can go into 1/8 cup?
Answers
Answer:
6 tps
Step-by-step explanation:
3 tsp = 1 tablespoons
16 table spoons = 1 cup
therefore 48 teaspoons = 1 cup
therefore 1/8th cup =6 teaspoons
Answer:
(1/8) cup = 6 U. S. teaspoons
Step-by-step explanation:
Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.
We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:
(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.

Distributive property
Step-by-step explanation:
8y + 4
We can factor out a 4 out of both as both are divisible by 4
8y / 4 = 2y
4 / 4 = 1
So 8y + 4 is the same as saying 4 * 2y + 4 * 1
This can be written as 4(2y + 1) which is written using the distributive property
