The graph shows the number of jam jars filled by two different machines over several minutes.The equation y = 3x represents the number of jars, y, Machine A fills in x min.

Which equation could represent the number of jars filled by Machine B?

a y = 1.5x

b y = 3x

c y = 6x

d y = 8x

Answers

Answer 1

Answer:

Answer:

a. y = 1.5x

Step-by-step explanation:

Both equations are equations of a line. All options have the form:

y = a*x

where y and x are the variables and a is the slope.

The slope of the equation corresponding to machine B is less than the machine A's slope (machine A line is above machine B line). The only option in which the slope is less than 3 is y = 1.5*x.

Answer 2

Answer: The correct answer is y = 1.5x, A.
I am sure it is because I took the K12 test. I used the answer from the other person that answered this, and got it wrong. I reviewed the test, and It says that 1.5x is correct.

What is the formula for a triangle

Answers

First...
You would represent the area with "A".
Then there should be height and base. Represent height with "h" and represent base with "b".
"b" times "h" then divide by two. That is the area. (I inserted a file so...:) )

Which is more 0.02 or 0.1 ?

Answers

0.1 is the same as 0.10. If you forget the decimal it is 02 and 10 which is the same as 2 and 10. 10 is bigger than 2 so the answer is 0.1

.1 because if you change .1 to = .02 it is .10 and .10 is bigger than .2

a trapezoid an area of 7.2 square miles.one base is 1.2 miles and the other is 2.4 miles long.what is the height

Answers

Area = 7.2 square miles

Base = 1.2

Second base = 2.4

Area of Trapezium = (1/2)*(Sum of Bases)*height

7.2 = (1/2)*(2.4 + 1.2)*h

7.2 = (1/2)*3.6*h

7.2 = 1.8h

1.8h = 7.2

h = 7.2/1.8 = 4

Height = 4 miles.

The manager of a public pool is counting the people who came to swim in June and July. There were 600 people who came in June. There were 800 people who came in July. What is the percent increase in people who came from June to July?25%

200%

3313%

75%

Answers

So,

The percent increase is basically the same as percent decrease except that you subtract the June count from the July count. If you let x be the June count and y be the July count, you can write it mathematically as follows:
$(y -x)/(x) = percent\ increase$

Substitute.
$(800 - 600)/(600) = percent\ increase$
$(200)/(600) \ or\ (1)/(3) = percent\ increase$

The percent increase in people from June to July is 33.3333333%, which is not one of the options you put there.
