Honestly, you don't really have to pay attention to the other numbers or ratios on the graph until you think you found your answer. Pay attention to whichever ratio you choose and follow these steps:

1. Identify which number is the cost and which is the amount of pens bought

2. Set it up as a division problem by using the cost and the dividend and the amount of pens as the divisor

3. After you have your answer, plot your ratio of 1:(your product) and if the line that was graphed is straight, you are correct.

four glasses of milk and 2 snack bars have a total of 68 carbohydrates​ (carbs), and 2 glasses of milk and 3 snack bars have a total of 62 carbs. Determine how many carbs are in one glass of milk and in one snack bar.

Answers

Answer: One glass of milk = 10 carbs

Answer: One snack bar = 14 carbs

Step-by-step explanation:

Four glasses of milk and Two snack bars.

4 x 10 = 40

2 x 14 = 28

40 + 28 = 68

Two glasses of milk and Three snack bars.

2 x 10 = 20

3 x 14 = 42

20 + 42 = 62

what is the slope of the line

Answers

Answer:

-3

Step-by-step explanation:

Slope is rise over run or the change in y over change in x. So to find the slope count the difference from one point to the next, for example (0,4) and (1,1). In this case, the y-value decreases by 3, so -3, and the x-value increases by 1, so +1. Which would be -3/1 or just -3. One way to visually check is to remember that slopes less than -1 or greater than 1 make the line steeper and negative slopes make the graph decrease from left to right.

Using a standard deck of playing cards, what is the probability of drawing a four, replacing the card, and then drawing a club?
A. 1/26

B. 1/51

C. 17/52

D. 1/52

Answers

Answer:

D. 1/52

Step-by-step explanation:

There are four 4s in a deck of 52 cards, so there is a 4/52 chance of drawing a four on the first try.

Once you replace the card in the deck, the simulation starts over, meaning the events are independent and you are once again drawing from 52 possible cards.

Now, when you draw the club, the chance of this is 13/52 because there are 13 clubs in a deck.

Because events are independent, multiply the probabilities to determine the chance that both events occur.

[tex]\frac{4}{52} * \frac{13}{52}[/tex]   =  1/52

A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 2,417,760,000 times in a year. About how many times faster does the sparrow's heart beat compared to the human heart? Show your work.

Answers

Answer: 1577.14

Step-by-step explanation:

From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.

To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:

= 2,417,760,000 / 1,533,000

= 1577.14 times

A school raises money by selling 0.5 bags of nuts.



They buy:

-30 pounds of cashews

-15 pounds of almonds

-5 pounds of peanuts



How many 0.5 pound bags can they make?

Answers

Answer:

100 bags

Step-by-step explanation:

Answer:

100 bags

Step-by-step explanation:

You're going to want to multiply each amount of pounds the bags are by two. So 30 × 2 is 60. 15 × 2 = 30. 5 × 2 = 10.

60 + 30 = 90

90 + 10 = 100

Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour. Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour. In how many hours will the altitude of moutain climber B be lower than the altitude of moutain climber A?

Answers

Answer:

the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.

Step-by-step explanation:

This talks about equalities in math,

We are told about Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour, this can be interpreted as

250 - 30h

Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour, this can be interpreted as

400 - 50h

We were now asked how many hours the altitude of mountain climber b be lower than the altitude of mountain climber A, we can interpret this as

(400 - 50h) < (250 - 30h )

We can collect the like terms here

-50h + 30h < 250 - 400

-20h < - 150

The negatives sign can cancelled out, we have

Note that multiplying or dividing by a negative THE INEQUALITY SIGN MUST BE FLIPPED

20h > 150

h > 150/20

h > 7.5

Therefore, the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.

Tannis's first machine could throw a car 272727 meters. She studied her first machine and built a better one. Her second machine could throw a car 777 times as far.
How far does the second machine throw a car?

Answers

Answer:

The rate of change of the distance between the cars at that instant is 5.46 meters per second

Step-by-step explanation:

Speed of first car = 7 m/s

Speed of second car = 3 m/s

At instant, distance of first car from intersection = 5 meters

distance of second car from intersection = 12 meters

Therefore, we have

Distance between both cars at intant = √(12² + 5²) = 13 m

Rate of change of distance is given by;

2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt

= 26dd/dt = 2×5×7 + 2×12×3 = 142

dd/dt = 142/26 = 5.46 m/s.

That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
