Answer:

Top right

Step-by-step explanation:

1). Top left graph shows the points forming a straight line when we join them.

It's a linear graph.

2). Top right graph having a curve represents an exponential graph.

3). Bottom left graph is having a straight line which represents a linear graph.

4). Bottom right graph shows a straight line which represents a linear graph.

Therefore, Graph in the top right doesn't belong the group.

each unit uses a chip 3/32 inches long how many units can be made if i have chips that are 9/16 inches long

Vikentia [17]

If you do 9/16 / 3/32 you can change that into 9/16 x 32/3 and cross multiply which gives you 512/27. And that equals 18.96 which you can round to 19. So you would be able to make 19 units if you use the 9/16 chips

A family has two cars. The first car has a fuel efficiency of miles per gallon of gas and the second has a fuel efficiency of mi

nexus9112 [7]

Answer:

The gallons of gas consumed by the first car is 35 and the second car is 30.

Step-by-step explanation:

There are some data missing in the question, so below is the question with complete data: $A\ family \ has \ two \ cars. \ The \ first \ car \ has \ a \ fuel \ efficiency \ of \ 40\ miles \ per \ gallon \ of \ gas$ $and\ the\ second\ has\ a\ fuel\ efficiency\ of\ 25\ miles\ per\ gallon\ of\ gas.$ $During\ one\ particular\ week,\ the\ two\ cars\ went\ a\ combined\ total\ of\ 2150\ miles,$ $for\ a\ total\ gas\ consumption\ of\ 65\ gallons.$ $How\ many\ gallons\ were\ consumed\ by\ each\ of\ the\ two\ cars\ that\ week?$

Now, to find the gallons consumed by each cars that week.

Let the gallons consumed by first car be $x.$

And let the gallons consumed by second car be $y.$

So, total gallons consumed by both cars:

$x+y=65\\\\y=65-x\ \ \ \ ......(1)$

Now, the combined total miles both cars went:

$x(40)+y(25)=2150$

Substituting the value of $y$ from equation (1):

$x(40)+(65-x)(25)=2150\\\\40x+1625-25x=2150\\\\1625+15x=2150$

Subtracting both sides by 1625 we get:

$15x=525$

Dividing both sides by 15 we get:

$x=35.$

The gallons consumed by first car = 35.

Now, to get the gallons consumed by second car by substituting the value of $x$ in equation (1):

$y=65-x\\\\y=65-35\\\\y=30.$

The gallons consumed by second car = 30.

Hence, the gallons of gas consumed by the first car is 35 and the second car is 30.

If the average (arithmetic mean) of four different numbers is 30, how many of the numbers are greater than 30 ?

IrinaVladis [17]

Answer:

Maximum 3 numbers. Minimum 1 number.

Step-by-step explanation:

Well, let us look at the case when 3 numbers are greater than 30. Let us take numbers as 1, 2, 3 and 114 and find their mean which is (1+2+3+114)/4=30.

Now let us look at the case in which 2 numbers greater than 30. Let us take numbers 28, 29, 31 and 32 and find their mean which is (28+29+31+32)/4=30.

Now let us look at the case in which 1 number greater than 30. Let us take numbers 27, 28, 29 and 36 and find their mean which is (27+28+29+36)/4=30.

So it can be concluded that maximum 3 numbers and minimum 1 number are greater than 30.
