Answers

Answer:

The total amount of juice is:

                      1.8 liters.

Step-by-step explanation:

It is given that:

olivia took out 8 glasses and poured juice from the pitcher.

The capacity of each glass is 3/10 liter.

If there was enough juice for 6 glasses.

This means that the amount of juice will be the total quantity of juice poured in 6 glasses.

Since, capacity of 1 glass= 3/10 liters=0.3 liters

Hence,

Capacity of 6 glasses= 6×0.3=1.8 liters.

Answers

Answer:

The relationship is rate is same.          

Step-by-step explanation:

Given : During the Labor Day weekend, Amy and Kathleen each ran in a race. Amy ran in a 5K and completed it in 31 minutes and 15 seconds. Kathleen ran in a half-marathon, which is 21.1 kilometers, and completed it in 2 hours, 11 minutes, and 52.5 seconds.

Let d represent distance in kilometers, r represent the rate, and t represent time in minutes.

To find : The proportional relationship ?

Solution :      

We know,

1 hour = 60 minutes = 60 × 60 seconds

First we find the rate of both Amy and Kathleen.

Amy ran in a 5 km and completed it in 31 minutes and 15 seconds.

Rate of Amy in km/hr is given by,

Kathleen ran in a half-marathon, which is 21.1 kilometers, and completed it in 2 hours, 11 minutes, and 52.5 seconds.

Rate of Kathleen in km/hr is given by,

Both man ran at the same speed.

Therefore, The relationship is rate is same.

Velocity=distance/time

a=5/(31*60+15)=5/1875=1/375

k=21.1/(2*3600+11*60+52.5)=21.1/7912.5=1/375

a=k

The both ran at the same speed.

(1km/375s)(3600s/h)=9.6km/h

Determine the coordinates of the x-intercept of 3x – 4y = 24.

Answers

The definition of an x intercept is when y equals 0. If y were to equal 0, you would have 3x -4(0)= 24, which is equal to 3x - 0 = 24. Using the addition property of equality, you would add 0 to both sides, and get 3x = 24. Finally, using the division property of equality, you have x = 8. So the coordinates of the x intercept would be (8,0), as your y was defined as 0. Hope this helps. Let me know if you have any questions about my explanation and feel free to ask more questions.
The x intercept is whre the line crosses the x axis or where y=0

so set y to 0 and solve for the value of x that makes the equation true

3x-4(0)=24
3x-0=24
3x=24
divide both sides by 3
x=8

x=8
y=0

(x,y)
(8,0)
the point is (8,0)

if a discount is received

Answers

Answer:

Option B - if an item receives a 20% discount

Step-by-step explanation:

A conditional statement is in the form of p q, where p is a hypothesis and q is a conclusion and is denoted in an if-then statement form. Like if p then q.

Given statement is:

A regularly priced item at a store receives a 20% discount. This is the conclusion part.

We have to find the hypothesis part.

If an item receives a 20% discount - then a regularly priced item at a store receives a 20% discount.

If an item receives a 20% discount
Random Questions
The incentive scheme that rules sumo is intricate and extraordinarily powerful. Each wrestler maintains a ranking that affects every slice of life; how much money he makes, how large an entourage he carries, how much he gets to eat, sleep, and otherwise take advantage of his success. The sixty highest-ranked wrestlers in Japan, comprising the makuuchi and juryo divisions, make up the sumo elite. A wrestler near the top of this elite pyramid may earn millions and is treated like royalty. Any wrestler in the top forty earns at least $170,000 a year. The seventieth-ranked wrestler in Japan, meanwhile, earns only $15,000 a year. Life isn’t very sweet outside the elite. Low-ranked wrestlers must tend to their superiors, preparing their meals and cleaning their quarters. . . . So ranking is everything. 1. Which of the following central ideas from the paragraph is a reason that supports the claim “cheating exists because of incentive.” A. Every wrestler has a ranking. B. Ranking affects your diet. C.
