Answer: 64 minutes to put as many boxes as possible.
Explanation: The dimensions of Ellie's boxes in meters are: 0.45m by 0.40m by 0.35 ( to convert from centimeters to meters we just divide by 100, because 1m =100cm). therefore the volume of each box is 0.063 m3
Now the dimensions of the empty van are 3.6m by 1.6m by 2.1 m, therefore its volume is: 12.096 m3

So the amount of boxes that Ellie can put in the van is equal to the volume of the van divided by the volume of each box: 192 boxes

So 192 boxes can be put into the van.
Now Ellie can put 3 boxes in the van in 1 minute, therefore the amount of time it will take her to put 192 boxes into the van will be: 64 minutes

So it takes Ellie 64 minutes to put as many boxes into the van as she can.

Answer: The correct answer is A

Step-by-step explanation:

At 1, there is a start of $45

Then for 2 it adds $25

Then 3 adds $25 dollars.

Because 1 started at $45, that means it is a rate of 25 dollars per hour, but a starting cost of 20+25= $45.

Write an equation for each graph in a slope
Intercept form

Answers

Answer:

y=2x-3

Step-by-step explanation:

Y-intercept can be read off the graph.

Slope can be determined using the formula:

y2-y1 divided by x2-x1 (Substitute co-ordinates)

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3

Answers

Answer:

B

Step-by-step explanation:

There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.

For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.

Top left = (-3,4)

Bottom left = (-2, -4)

Top right = (3,4)

Bottom right = (1,-4)

The answer is B.

(-3,4) is the point/dot on the top left corner.

(3,4) is the point on the top right corner.

(1,-4) is the point on the bottom right corner.

(-2,-4) is the point on the bottom left corner.

A store is going out of business, they are advertising that "Everything is 40% Off!" You have had your eye on a new pair of shoes that were originally $156. What is the sale price of the shoes?

Answers

Answer:

$93.6

Step-by-step explanation:

The original price if this show is to be sold at $156

But the question tells us that everything is being sold with a 40% off.

So we should get 40% of 156

= 0.40 * 156

= $62.4

So this shoe would have it's new price to be $(156 - 62.4) = $93.6

So in conclusion given a 40 percent off, the sales price if the shoe would be $93.6

Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 555 salamanders, 333 crayfish, and 121212 minnows in her lab.
What is \text{P(salamander})P(salamander)start text, P, left parenthesis, s, a, l, a, m, a, n, d, e, r, end text, right parenthesis?
If necessary, round your answer to 222 decimal places.

Answers

Answer:

1/4

Step-by-step explanation:

Given

amount of  salamanders, = 5

amount of crayfish = 3

amount of minnows = 12

Total fish = Total outcome = 5+3+12

Total outcome = 20

Since we are looking for the probability of selecting  salamanders, our expected outcome will be 5.

Probability = expected outcome/total outcome

Pr( salamanders,) = 5/20

Pr( salamanders) = 1/4

Hence the probability of selecting  salamanders, is 1/4
