How to you graph a linear equation when all they say is y=4 what to do

Answers

Answer 1

Answer: -- Find any point where y=4

-- Find another point where y=4

-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.

The equation for every straight line is [ y = mx+b ].

This is the line where (m = 0) and (b = 4).

Answer 2

Answer: A horizontal line that intersects the graph at (0,4)

A spinner has three equal sections of red, blue, and yellow. If the spinner is spun 250 times how many will the spinner land on a color that is not blue.

Answers

There are three equal sections on the spinner: one is red, one is blue, and one is yellow.

From this, we can figure out that the probability of the spinner landing on the blue section is 1/3. Thus, the probability of the spinner not landing on the blue section is 1 - 1/3 or 2/3.

Therefore, if the spinner is spun 250 times, and we are trying to figure out how many times it WON'T land on blue, then we multiple the probability of this happening (2/3) by the number of times that we spin the spinner (250).

2/3 * 250 = 166 2/3

If the spinner is spun 250 times, it will land on a color that is not blue 166 2/3 (approximately 167) times.

Answer:

167 if you round it up.

The science fair judges will be science teachers and volunteers. Each judge will only have time to view 5 science fair projects. There are 133 science teachers. What is the fewest number of volunteers needed to have enough judges for all of the projects?

Answers

Answer: The fewest number of volunteers needed to have enough judges for all of the projects is 2.

Step-by-step explanation:

Number of science teachers = 133

Number of science fair projects viewed by each judge = 5

Let the number of judge be n

Since number of volunteers must be multiple of 5 .

According to question,

$5n=135+\text{number of volunteers}\n\n\text{ where, n is a natural number and number of volunteer must be integer}$

So, Possibility for number of volunteers must be 2 to make it divisible by 5.

$5n=133+2\n\n5n=135\n\nn=(135)/(5)\n\nn=27$

Hence, the fewest number of volunteers needed to have enough judges for all of the projects is 2.

the answer is twenty seven

3/5 =2/3t what is t PLZ HELP

Answers

$3/5 = (2/3)t$
cross multiply
$9/10 = t$

2/3t = 3/5

Divide (inverse operation)

2/3t/2/3 = 3/5 divided by 2/3

3/5 * 3/2 = 9/10

t = 9/10

Answer: t = 9/10

Suppose the diameter of a circle is 10. What is its area?

Answers

Well hello again :3. This is also quite simple. The diameter of a circle is 2 times the radius. So we can refit this into the equation and say that our new formula using diameter is $pi(d^2/2)$ . Now we can say that 10/2 is 5 and $5^2$ is 25. Therefore your answer is $25pi$ or 78.54.

To find area you must use the formula A= pi*radius. So the radius is always 1/2 of the diameter. 10/2 is 5.So your radius is 5. multiply 5 by 3.14, to get the area of 78.54
