A cook removes a package of food from a freezer and begins to defrost the package. • The initial temperature of the package of food is -15°F. • At noon, the temperature of the package of food has increased to 35°F. What is the total change in temperature, in degrees Fahrenheit, for the package of food? Show your work.
Answer:
50 degrees Fahrenheit
Step-by-step explanation:
add 15f to cancel -15f and add the 35f left which is 50f

then y =
Answer:
y= 1-x
Step-by-step explanation:
● (a^2x)/a^(x-y) = a
This means that:
● 2x-(x-y) = 1
● 2x - x +y = 1
● x + y = 1
Substract x from both sides
● x+y -x = 1-x
● y = 1-x
which line segment could be a midsegment of ∆abc
Answer:
\(\overline{DF}\) could be a midsegment of ∠ABC.
Step-by-step explanation:
A midsegment of a triangle must be two things:
1. Parallel to the 3rd side, in this case, \(\overline{AD}\).
2. Half the length of the 3rd side, in this case, \(\overline{AD}\).
Since we don't know the lengths, we can only go off of 1. There is only one line that is parallel to \(\overline{AD}\) and it is \(\overline{DF}\).

Use the elimination method to solvethe system of equations. Choose the
correct ordered pair.
-x+y= -2
2x- 3y = 4
Answer: 2(−x+y=−2)
2(−x+y=−2)
1(2x−3y=4)
Becomes:
−2x+2y=−4
2x−3y=4
Add these equations to eliminate x:
−y=0
Then solve−y=0for y:
−y=0
−y/-1 = 0/-1 (Divide both sides by -1)
y=0
Step-by-step explanation:
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+y=−2
Substitute 0 for y in −x+y=−2:
−x+0=−2
−x=−2(Simplify both sides of the equation)
−x/-1 = -2/-2 (Divide both sides by -1)
x=2
Answer:
x=2 and y=0
Answer: x=y+2
Step-by-step explanation:
Step 1: Add -y to both sides.
−x+y+−y=−2+−y
−x=−y−2
Step 2: Divide both sides by -1.
-x/-1 = -y - 2/-1
asnwer: x=y+2
Answer: x = 3/2y + 2
2x−3y=4
Step 1: Add 3y to both sides.
2x−3y+3y=4+3y
2x=3y+4
Step 2: Divide both sides by 2.
2x/2 = 3y + 4/2
answer: x = 3/2y + 2

which of the following expressions is equivalent to -10?
a.-7 3
b.-3 - 7
c.3 - 7
d.7 - 3
The expression which is equivalent to -10 is the option b, -3 - 7.
Explanation:
We can use subtraction and addition of integers to get the value of the given expression. We can write the given expression as;
-3 - 7 = -10 (-3 - 7)
The addition of two negative integers will always give a negative integer. When we subtract a larger negative integer from a smaller negative integer, we will get a negative integer.
If we add -3 and -7 we will get -10. This makes the option b the correct answer.

The length of the line segment AC and AG will be 6√2 units and 6√3 units, respectively.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
AB = 6
BC = 6
CG = 6
Then the length of diagonal AC is given as,
AC² = AB² + BC²
AC² = 6² + 6²
AC = 6√2
Then the length of diagonal AG is given as,
AG² = AC² + CG²
AG² = (6√2)² + 6²
AG = 6√3
The length of the line segment AC and AG will be 6√2 units and 6√3 units, respectively.

A community hall is in the shape of a cuboid.
The hall is 40 m long, 15m wide and
3 m high.
The community hall needs re-decorating
with new paint for the walls and ceiling,
and new tiles on the floor.
A 10 litre tin of paint covers 25 m² and costs £10.
Work out the total cost of paint needed
to re-decorate the community hall.
The total cost of painting is $564.
What is surface area of cuboid ?
A cuboid is a three-dimensional figure enclosed by six rectangular planes, each of which has a different size in terms of length, breadth, and height. Anything in the shape of a rectangle, such as a box, brick, or other object, may be a cuboid if you look about. When viewed from any of the ends, a cuboid (3-dimensional) can be seen to be made up of different-sized rectangles (2-dimensional). A cuboid's area is its surface because it is a solid with three dimensions. Since a cuboid's faces are rectangular, its area may be determined using the formula for the area of a rectangle.
Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Area of walls and ceiling = 2( 40*15) + 2(3*15) + (40*3)
=> Area of walls and ceiling = 2(600)+2(45)+120
=> Area of walls and ceiling = 1200+90+120
=> Area of walls and ceiling = 1410 \(m^2\)
Therefore, the area of walls and ceiling is 1410 square meters.
Here Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter.
Then total cost of paint = 10*\(\frac{1410}{25}\) = 10*56.4 = $564.
Hence cost of paint is $564.

Consider the following system of equations: y=2x−2 6x+3y=2 The graph of these equations consists of two lines that: 1. intersect at more than one point. 2. intersect in an infinite number of points. 3. intersect at exactly one point. 4. do not intersect.
Answer:
3. Intersect at exactly one point. ( (2/3), (-2/3) )
Step-by-step explanation:
To make the comparison of these lines easier, let's rewrite the 2nd equation into slope-intercept form, as the 1st equation is in slope-intercept form.
[1] y = 2x - 2
---------------------
[2] 6x + 3y = 2 ==> 3y = 2 - 6x ==> y = -2x + (2/3)
[2] y = -2x + (2/3)
So now that we have both equations in slope-intercept form, we can see that the two equations are both linear, have different slopes, and have different y-intercepts.
Since these equations have both different slopes and different y-intercepts, we know that the lines will cross at least one point. We can confirm that the lines only cross at a single point using the fact that both equations are linear, meaning there will only be one point of crossing. To find that point, we can simply set the equations equal to each other.
y = 2x - 2
y = -2x + (2/3)
2x - 2 = -2x + (2/3)
4x = (8/3)
x = (8/12) = (2/3)
And plug this x value back into one of the equations:
y = 2x - 2
y = 2(2/3) - 2
y = (4/3) - (6/3)
y = (-2/3)
Thus these lines only cross at the point ( (2/3), (-2/3) ).
Cheers.

I don't understand the question
acid solution a has a 50% acid concentration, and acid solution b has a 20% acid concentration. how many ounces each of solution a and solution b must be mixed to produce 100 ounces of an acid solution with a 41% acid concentration?
Solution a needed 70 ounces and solution b needed 50 ounces
What does "1 ounce" mean?
One ounce weighs 437.5 grains or 28.349 grams and is a sixteenth of a pound (avoirdupois) of weight.
One ounce, abbreviated "oz," equals 480 grains, or 31.103 grams, and is one-twelfth of a Troy or Apothecaries' pound in weight. abbreviation for fluid ounce. a tiny amount or percentage.
So, let x=the of ounces of the 50% acid solution. The total volume after both are mixed is 100 ounces so the amount of the 20% solution will be 120-X. The equation will therefore be:
50% * x + 20% * (100-x) = 41% * 100
Dropping the ‘%’ we get
50x + 2000 - 20x = 4100
30x = 2100
x = 2100/30 = 70
Hence 70 ounces will be needed
Solution a = 70 ounces
Solution b = 50 ounces
