Answer 1

Answer:

Answer:

Option B.

Step-by-step explanation:

The given graph represents the relationship between the number of chores, x that Larissa completes and the amount of money that she earns, y.

From the given graph it is clear that the equation of best fit line is

$y=2.09x+0.93$

We need to find the expected number of chores completed if she earns $5.

Substitute y=5 in the above equation and find the value of x.

$5=2.09x+0.93$

Subtract 0.93 from both sides.

$5-0.93=2.09x+0.93-0.93$

$4.07=2.09x$

Divide both sides by 2.09.

$(4.07)/(2.09)=x$

$1.947368421=x$

$x\approx 2$

Therefore, the correct option is B.

Start time: 7:15 A.M. Elapsed time: 2 hrs 20 mins End time?

Answers

The time would be 9:35 am

Hi, Mystic0user0!
So the question is asking for the time 2 hours and 20 minutes after 7:15.

It's a lot like adding numbers.

So first add the minutes. 15+20 minutes. That would give you 35 minutes.

Then add the hours. 7+2. That would be 9 hours since there is no carry over from the minutes.

The End Time would be 9:35 AM.

Hope this helps :)

A cone-shaped container sits inside a larger cone. The inner cone has a height of 3 in. and a diameter of 6 in. The outer cone has the same diameter and is 15 in. tall. The extra space in the outer cone is filled with crushed ice to keep the contents of the inner cone cool.

Answers

What is the volume of the crushed ice?

volume of the cone = π r² h/3

volume of the small cone = 3.14 * (3in)² * 3in/3
volume of the small cone = 3.14 * 9in² * 1in
volume of the small cone = 28.26 in³

volume of the big cone = 3.14 * (3in)² * 15in/3
volume of the big cone = 3.14 * 9in² * 5in
volume of the big cone = 141.30 in³

volume of the crushed ice = 141.30 in³ - 28.26 in³ = 113.04 in³
