Answers

Complete question :

Mi-Young makes 24 cups of seafood kalguksu.This is 60% of the total kalguksu she makes. Total kalguksu made is?

Answer:

40 cups

Step-by-step explanation:

Given that :

24 cups = 60% of total made

Let total kalguksu made = x

Hence,

24 cups = 0.6x

24 = 0.6x

Divide both sides by 0.6

24/0.6 = x

x = 40

Hence, total seafood Kalguksu made = 40 cups

An equipment rental company charges $40 per day to rent a trench digger. A construction crew rented a trench digger for 6 days and paid 270. Write a linear equation in slope-intercept form that represents the total cost to rent the trench digger as a function of the number of days.


What should x and y equal, what is the y-intercept, and what is the equation


BTW THIS IS 40 POINTS

Answers

Answer:

y = 40x + 30

Step-by-step explanation:

$40 per day represents the slope

Finding the y-intercept:

270 - 6*40 = 30

The function is then:

y = 40x + 30

List the intercepts of the graph.

Answers

Answer:

D

x-intercepts = (-[tex]\frac{\pi }{2}[/tex],0), ([tex]\frac{\pi }{2}[/tex],0)

y-intercept = (0,3)

x intercepts: when y = 0
Points (-pi/2,0) and (pi/2,0)
y intercept: when x = 0
Point (0,3)
The answer is D

  a) 9/2 = 4.5, bushels per hour

  b) (3, 10), (6, 20), (9, 30), (12, 40)

  c) Shawn

Step-by-step explanation:

a) The line goes through the grid point (4, 18), so its slope is ...

  18/4 = 4.5 . . . . slope = "unit rate"

The units are (y-units)/(x-units) = bushels/hour.

__

b) You have correctly filled in the table.

Time-values are 3, 6, 9, 12.

Fruit values are 10, 20, 30, 40.

The unit rate for Carla is ...

  10 bu/(3 h) = 3 1/3 bushels/hour ≈ 3.33 bushels/hour

__

c) Shawn's unit rate of 4.5 bushels per hour is greater than Carla's unit rate of 3.33 bushels per hour. Shawn picked fruit at a faster pace.

Jordan makes two batches of cookies each week for her book club. Each batch of cookies needs 1 2/3 cups of flour. If she starts with 16 1/2 cups of flour, for how many weeks can she make cookies? Explain your solution.

Answers

Answer:

She can make cookies for 4.95 weeks

Step-by-step explanation:

2 x 1 2/3 = 3.333333333

16.5/ 3.333333333 = 4.95

Since Jordan is making two batches of Cookies per week, you need to multiply 2 by the amount of resources needed to bake one batch of cookies. So you multiply 1 and 2/3 by 2 to get the amount of resources neccesary for one week of making cookies. Then, you take the full amount of resources that she has, and divide that by the amount she uses per week, that number will give you the number needed to figure out how many weeks she has to bake cookies.

To figure out the number that is being divided to get the whole number in weeks, you would take the 16.5 cups of flour. The reason why this is, is because that Is the starting number of cups that she has. So here you would need to divide the amount you are taking from it each week. This will result in the amount of weeks that she is able to bake cookies with her flour.

Find the probability of drawing two diamonds in a row from a standard deck of 52 cards. After the first card is drawn it is set aside and not returned to the deck.

Answers

Answer: 1/17

Step-by-step explanation:

First and foremost, we should note that there are 13 diamonds in a standard deck of 52 cards.

If the first card is drawn, the probability of picking a diamond is 13/52. Since it's not replaced, when another one is picked, the probability that it will be diamond will be 12/51.

We then multiply both together. This will be:

= 13/52 × 12/51

= 1/4 × 4/17

= 1/17

You have made a poster that is 4 feet by 5 feet to hang on a wall, you want to use the reaming 10 sqaure feet of fabric to add a decorative border width. What should the width of the border be

Answers

Answer:

0.556 foot wide or 6 ²/₃ inches wide

Step-by-step explanation:

first we must calculate the total perimeter of the poster that will be decorated with the fabric:

the total perimeter of the poster = 4 + 4 + 5 + 5 = 18 feet long

you have 10 square feet of fabric, so its width should be 10 / 18 = 0.556 foot wide or 6 ²/₃ inches wide

A school has 100 students. on friday, 70 students went on a field trip. what percent of the students did not go on the field trip

Answers

Using percentages we know that 30% of students did not go on the field trip.

What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.

So, the percentage of children that did not go to school:

The total number of students is 100.Students that went on the trip are 70.

Students that did not go:

100 - 70 = 30 students

30 students are % of 100:

30/100 × 100.30 × 10030%

Therefore, using percentages we know that 30% of students did not go on the field trip.
