Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden. Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam. This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears. Which batch of jam tasted more like cranberries?

Answers

Answer:

The batch of jam from this summer

Step-by-step explanation:

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.

For last summer

Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.

Hence,

5 cup of pears = 3 cups of cranberries

1 cup of pears = x

Cross Multiply

5x = 3

x = 3/5

x = 0.6

1 cup of pears = 0.6 cup of cranberries

For this summer

This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.

Hence,

8 cup of pears = 5 cups of cranberries

1 cup of pears = x

Cross Multiply

8x = 5

x = 5/8

x = 0.625

1 cup of pears = 0.625 cup of cranberries

From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer

Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer

Answer:

This summer’s batch jam tasted more like cranberries.

Write an equation and solve the problem.

Answers

Answer:

the answer would be 5 hours

Step-by-step explanation:

we know he has 3000 miles to travel so if he travels 600 mph than you would have to divide.

3000/600 = 5

another way you could solve it is to take two zeros from each point so that you have 30 and 6, then you divide then.

Answer:

For an equation like:

y = a*x + b

a is the slope, and this is the rate of change of the function.

For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.

Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.

The left triangle has 96°,44°, and y°.


The middle triangle has 39°,x°,and y°.


The triangle on the right has 121°,39°, and w°


First you’ll solve for y° using the left triangles values which will be 40°.


Then you will solve for the x° using the middle triangles values which will be 101°


Lastly you’ll solve for the w° using the triangle on the right which will be 20°

Answer:

Step-by-step explanation:

1). Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

   m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   Therefore, slope of the line passing through two points (2, -10) and (-2, 18) will be,

   m = [tex]\frac{-10-18}{2+2}[/tex]

  m = -7

2). From the table attached,

    Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

    Slope of line passing through (4, -6) and (0, -2) will be,

    Slope = [tex]\frac{-6+2}{4-0}[/tex]

    Slope = -1

Answers

Answer: a) 1800g b) 300g c) 1200g

Step-by-step explanation:

a) 1.8 x 1000 = 1800g

b) 1800g / 6 toys= 300g > the weight of one toy

c) 300g x 4 toys = 1200g / 1000 = 1.2 kg

Answer:

a. 1.8kg to grams

1000g =1kg

x =1.8kg

cross multiply

x = 1.8 x 1000

x= 1800g

b. weight of one toy

6 toys = 1800g

1 toy = 1800÷6

1 toy = 300g

c. 1kg = 300g

4toys = x

x = 4 x 300

x = 1200g

1200g to kilogram

1000g = 1kg

1200g = x

cross multiply

1000x = 1200

x = 1200÷1000

x = 1.2kg

Answers

First, find the slope using the equation, y2 - y1 / x2 - x1

1-5 / 4 - - 4 = -4/8 =  -1/2

plug this into slope intercept form

y = -1/2x + b

Next use one of the points to find b using point-slope form. I will use (4,1)

y - y1 = m ( x - x1)

y - 1 = -1/2 (x - 4)

y -1 = -1/2x + 2

+1                  +1

y = -1/2x + 3 is your equation

Other Questions
Vicky Torres and Juanita Alva were the first in line at Best Buy during a Black Friday sale so that they could secure a large-screen TV, which was normally $499 and was advertised on sale at $199. Because they arrived three weeks early, they ended up waiting in line for a total of 500 hours! The authors of your textbook found their choice puzzling because of the high opportunity cost in this scenario. The authors say: "Saving $300 by spending 500 hours makes Vicky and Juanita's time worth 60 cents an hour. They could have spent 30 hours working an extra job at $10 an hour and each earned enough money to purchase the TV at full price-and still had 470 hours to do other things. In short, they don't seem to have been aware of the opportunity cost of waiting in line." But this is not the only conclusion one can draw from Vicky and Juanita's behavior. Choose the conclusion below that would be consistent with the idea that Vicky and Juanita were aware of the opportunity costs yet still found the three-week-wait to be worthwhile. a. "However, they might have enjoyed the experience of camping out in line, meeting other customers, and gaining a degree of fame for their commitment to getting a good deal." b. "Vicky and Juanita really enjoy their high paying jobs and don't like camping at all."c. "If they are able to camp out for three weeks, they probably do not have full-time jobs, so earning 60 cents an hour is a good decision for the shoppers." i did not mean to make this A card is drawn from a standard deck of 52 playing cards.
