A chef needs to choose a pan that will allow food to cook as quickly as possible for a special recipe and has decided that he will use one of three pans. Each pan has the same dimensions and design but is made of a different type of metal. The chef will design an experiment that will test and rank the thermal conductivity of the pans by cooking a hamburger patty to an internal temperature of 170 °F in each pan on the same stove burner. The thermal conductivity is the rate of transfer of energy in the form of heat over a period of time through a material.
Describe how thermal conductivity can be measured and compared for each of the pans.

A 6-pound bag of sugar costs $7.98. What is the unit price?
Answers
Answer:
1.33
Step-by-step explanation:
Lets start by making a quick equation:
Total cost is y, or 7.98, with the weight being 6 pounds. We are looking for the unit price, which will be our x.
7.98 = 6x
Divide 6 by both sides:
7.98 / 6 = 6x / 6
This gets rid of the 6 on the right, so we are left with:
1.33 = x
So the unit price is $1.33 per pound.
I hope this helps! :)

Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 centimeters. Round to the nearest tenth.
*there is no diagram*
Answers
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³

Answer:

Step-by-step explanation:
I think that's right. Quadrant IV is when (x, -y)
The point in Quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane is (2.5, -6.5)
What is the coordinate plane?A coordinate plane is a two-dimensional plane formed by the intersection of two number lines.
Given that, there is a point in quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane.
If we have a coordinate point (x, -y) in quadrant 4, if the coordinate is 4 units away, the resulting coordinate will be expressed as (x+4, y-4)
(-1.5+4, -2.5-4) = (2.5, -6.5)
Hence, The asked point is, (2.5, -6.5)

Answer:
See Below
Step-by-step explanation:
Lets look at our numbers:
The balloon is at 1000 feet.
The balloon drops at a constant speed of -4 1/2 per second.
How long will it take to get to 215ft, in seconds, s.
Lets see, if you were to subtract 1000-215, you will get 785.
The balloon needs to drop 785ft to get to 215ft above the ground.
The question asks how long will it take to get below 215ft.
Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.
**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.
Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,
