An engineering student is studying the effects of cryogenic treatments on a particular material. The treatment involves cooling the material with specific applications of liquid nitrogen.
Answers
Answer:
The answer is "choice C"
Step-by-step explanation:
Please find the complete question in the attached file.
This is because the temperature in grades Celsius, y, of material could be represented by the previous diagram, in which x is the period, in hours.
It is evident from the study that, the y-intercept is 40 degrees Celsius and thus the temperature difference is 40.
That edge of the top paraboloid is (15-200) so at most -200 ° C at 15 hours the temperature of the material. During 30 hours, the material returns to its initial temperature as the temperature at x = 30 is 40 °C.

A collection of nickels and quarters is worth $2.10. There are 22 coins in all . How many of each coin
are there?
Answers
Answer:
17 nickels
5 quarters
Step-by-step explanation:
Let n = no. of nickels
22 - n = no. of quarters
Each quarter is 25 cents and each nickel is 5 cents
5n = total amount of money in cents for the nickels
25(22 - n) = total amount of money in cents for the quarters
Since the total amount of money is $2.10 or 210 cents we have the equation
5n + 25(22 - n) = 210
5n + 550 - 25n = 210
-20n + 550 = 210
-20n = -340
n = 17 nickels
22 - n = 22 - 17 = 5 quarters
Now, you don't need to do all that I did. I explained in detail what is going on in this problem. All that you would need to do is write this:
let n = no. of nickels
22 - n = no. of quarters and then write the equation and solve
5n + 25(22 - n) = 210
?? OK?

What is the area of this triangle? A=bh/2 17 m² 30 m² 60 m² 120 m² Right triangle with height labeled 12 m, base labeled 5 m, and third side labeled 13 m.
Area of a triangle = bh/2
b = Base = 5m
h = Height = 12m
Area of the triangle = 5m × 12m/2
= 60m²/2
= 30 m²
Answer:30 m²

You are organizing a school banquet. You spend $82 on decorations. Dinner will cost $13 for each person that attends. In the equation y=13x+82, y is the total cost of the banquet for x people. Complete the solution (69,?) to find the cost for 69 people.
Answers
Answer:
(69,979)
Step-by-step explanation:
In the coordinates, x is represented as 69. We can now insert this into the equation.
y = 13x + 82
Now to insert x.
y = 13(69) + 82
Now we can multiply 13 by 69.
13*69 = 897
Now fix the equation.
y = 897 + 82
Now add to get our y.
897 + 82 = 979
Substitute into the equation.
y = 979
And there is our answer. We now need to put this into the coordinates.
And we get our final answer of (69,979).

The iron cross is a skiing trick in which the tips of the skis are crossed while the skier is airborne. Find the value of $x$ in the iron cross shown.
A photo shows the tips of the skis crossed each other while performing iron cross in skiing. Two pairs of opposite angles are formed during crossing. One pair of the opposite is labeled 127 degrees and left parenthesis 2 x plus 41 right parenthesis degrees. PS the image is the given degrees! PLLLSS help I am timed and I need to raise my grades!!!!
Answers
Answer:
43 = x
Step-by-step explanation:
well so you have 127 degrees = (2x + 41)
so get the x by itself
127 - 41 = 86
2x + 41 - 41 = 2x
86 = 2x
86 / 2 = 43
2x / 2 = x
43 = x
The value of x is 43°.
Here,
The iron cross is a skiing trick in which the tips of the skis are crossed while the skier is airborne.
A photo shows the tips of the skis crossed each other while performing iron cross in skiing.
Two pairs of opposite angles are formed during crossing.
One pair of the opposite angle is 127° and (2x + 41)°.
We have to find the value of x.
What is Vertically opposite angles?
The angles opposite each other when two lines cross called Vertically opposite angles.
Now,
Two pairs of opposite angles are formed during crossing.
One pair of the opposite angle is 127° and (2x + 41)°.
Clearly, Both angle are equal;
2x + 41 = 127
2x = 127 - 41
2x = 86
x = 43
Therefore, Value of x is 43°.

Sebastian is making bags of trail mix for hiking club. He will use 21 ounces of walnuts, 10.2 ounces of almonds, and 15.6 ounces of cashews. This amount makes 24 bags of trail mix. How many ounces are in each bag?
Answers
Answer:
1.95 ounces
Step-by-step explanation:
ounces in each bag = total ounces in 24 bags / number of bags
total ounces in 24 bags = 21 ounces of walnuts + 10.2 ounces of almonds + 15.6 ounces of cashews = 46.8 ounces
46.8 / 24 = 1.95 ounces
