The sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.
What is specific heat?The specific heat of a substance is the amount of heat needed, to raise the temperature of the of one gram of substance by unit degree Celsius.
The specific heat capacity of the substance can be given as,
[tex]C=\dfrac{Q}{m\Delta T}[/tex]
Here, (m) is the mass of the substance, (Q) is heat energy and
is the change in temperature.
The above formula can be rewritten as,
[tex]{Q}={m\Delta T}C[/tex]
By this formula, we can say that the heat energy is directly proportional to the specific heat of the substance.
Thus the value of heat energy required to warm up the substance will be higher with the higher value of specific heat and result of it the substance require more time to warm up.
Here, the specific heats of these substances are:
Treated glass = 0. 75 J/g • °C
Aluminum = 0. 90 J/g • °C
Stainless steel = 0. 50 J/g • °C
Copper = 0. 39 J/g • °C
In the above data, the value of specific heat of copper is less than other three substances.
Hence, the sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.

Answer: 30° and 110°
55° and 85°
70° and 70°
The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:
= 180° - 40°
= 140°
Therefore,
30° + 110° = 140°
55° + 85° = 140°
70° + 70° = 140°

16.5 is 12% of what number?
Answer:
Let's set up an equation;
12/100 * x = 16.5
where 12/100 is 12%
x is the number of the 12%
that would equal 16.5
So solve for x;
12/100 * x = 16.5
12/100x = 16.5
0.12x = 16.5

Step-by-step explanation:
This is a distance versus time graph. The slope on a given interval gives you speed.
So if the slope is going upwards, the speed is increasing which means it isnt constant
If going downwards, the speed decreasing, which means it isn't constant
If forming a horinzontal line, it has slope of 0, which means that it has a constant speed
The only time speed is constant is at 4.

Anitra sells cosmetics by mail and weighs each package before sending it.
The table shows the number of each item in a particular package and the total weight.
The system of equations can be used to show the relation between the items in a package and the weight of the package.
The system of equations for this problem is defined as follows:
3x + y = 21.2x + 2y = 24.From the first equation, we have that:
y = 21 - 3x.
The second equation is given as follows:
2x + 2y = 24.
Simplifying the equation, we have that:
x + y = 12.
Replacing the first equation, we have that the value of x is obtained as follows:
x + 21 - 3x = 12
2x = 9
x = 4.5.
Then the value of y is of:
4.5 + y = 12

Maria has $32. She earns $12 for 1 hour of cleaning. She wants to buy a birthday gift for her friend for $125. Enter the minimum number of hours Maria must tutor to be able to buy the gift
Answer:
8 hours
Step-by-step explanation:
First, you must subtract $32 from $125. You end up with $93.
Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.
96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.
While working on homework last night, Kayla completed 4 homework assignments in 3.2 hours. The same night, Karen completed 6 homework assignments in 5 hours. Who spent the least amount of time on homework per hour?
Answer:
Kayla
Step-by-step explanation:
To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework
Kayla: 3.2 ÷ 4 = 0.8
Karen: 5 ÷ 6 = 0.833
Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.
