Answer:
120 mL of 10% HCL will be used.
Step-by-step explanation:
to solve this, we have to generate an equation for the mixture, to get the volume of 10% HCl needed.
Let the volume needed = x
5% of x + (20% of 60ml) = 10% of ( 60 + x) ml of new mixture
0.05x + (0.2 × 60) = 0.1 × (60 + x)
0.05x + 12 = 6 + 0.1x
12 - 6 = 0.1x - 0.05x
6 = 0.05x
x = 6 ÷ 0.05
x = 120
Therefore, 120 mL of 10% HCL will be used.

The price-demand and cost functions for the production of microwaves are given as
p = 275 − x 60
p = 275 - x 60
and
C(x) = 50000 + 30x
where x is the number of microwaves that can be sold at a price of p dollars per unit and C(x) is the total cost (in dollars) of producing x
Required:
a. Find the profit function in terms of x.
b. Find the marginal cost as a function of x.
c. Find the revenue function in terms of x.
d. Find the marginal revenue function in terms of x.
Answer:
ALTERNATIVE 1
a. Find the profit function in terms of x.
P(x) = R(x) - C(x)
P(x) = (-60x² + 275x) - (50000 + 30x)
P(x) = -60x² + 245x - 50000
b. Find the marginal cost as a function of x.
C(x) = 50000 + 30x
C'(x) = 0 + 30 = 30
c. Find the revenue function in terms of x.
R(x) = x · p
R(x) = x · (275 - 60x)
R(x) = -60x² + 275x
d. Find the marginal revenue function in terms of x.
R'(x) = (-60 · 2x) + 275
R'(x) = -120x + 275
The answers do not make a lot of sense, specially the profit and marginal revenue functions. I believe that the question was not copied correctly and the price function should be p = 275 - x/60
ALTERNATIVE 2
a. Find the profit function in terms of x.
P(x) = R(x) - C(x)
P(x) = (-x²/60 + 275x) - (50000 + 30x)
P(x) = -x²/60 + 245x - 50000
b. Find the marginal cost as a function of x.
C(x) = 50000 + 30x
C'(x) = 0 + 30 = 30
c. Find the revenue function in terms of x.
R(x) = x · p
R(x) = x · (275 - x/60)
R(x) = -x²/60 + 275x
d. Find the marginal revenue function in terms of x.
R(x) = -x²/60 + 275x
R'(x) = -x/30 + 275
For these problems,
x
will represent the number of items and
y
will represent the money.
The fixed costs for a certain item are $100 per week. The cost to produce each item is $6 per item.
Using this information, what is the cost equation? Give your answer in slope-intercept form:
Answer:
y = 6x + 100
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the cost to produce each item and b is the fixed cost. Let's input the given values for m and b into the equation:
y = 6x + 100
This is the cost equation. $6 multiplied by x amount of items pluss the fixed cost of $100 gives you the total cost (y) to produce x amount of items.

Tell which angles are congruent to the given angle measure.
Generally:
- Vertical angles are congruent. An example of vertical angles on the diagram are angles 1 and 4; they are opposite each other on the two intersecting lines.
When two parallel lines are intersected by a transversal:
- Corresponding angles are congruent. Corresponding angles are angles on the same side of the transversal with corresponding positions, such as angles 2 and 5 in the diagram.
- Alternate interior angles are congruent. Angles 3 and 5 are an example of alternate interior angles on the diagram. They are contained within the interior of the two parallel lines, and are on opposite sides of the transversal.
- Alternate exterior angles are congruent. These angles lie on the outside of the parallel lines and on opposite sides of the transversal. Angles 1 and 7 are an example of alternate exterior angles.
Looking at the diagram, we can recognize that our given angle of 56° creates a vertical angle pair with angle 7; these angles are congruent. Additionally, since corresponding angles are congruent, angles 4 and 7 are congruent. Notice that angle 4 creates a vertical angle pair with angle 1, and that angle 1 also corresponds to the given angle.
Answer:The angles which are congruent to the given angle measure are:
∠1, ∠4 and ∠7

What is the slope of the line?y=1/3x+2
Answer:
THis equation is in slope-intercept form (y=mx+b)
in this equation m represents the slope.
Therefore 1/3 is the slope
1/3
Step-by-step explanation:
Answer: m = 1/3
Step-by-step explanation: Since the equation of this line is written
in slope-intercept or y = mx + b form, its slope or m is represented
by the coefficient of the x term which in this case is 1/3.
The half-life of the radioactive element unobtanium-43 is 10 seconds. If 48 grams of unobtanium-43 are initially present, how many grams are present after 10
seconds? 20 seconds? 30 seconds? 40 seconds? 50 seconds?
Answer:
At time, 10 seconds, the mass remaining is 24 grams
At time, 20 seconds, the mass remaining is 12 grams
At time, 30 seconds, the mass remaining is 6 grams
At time, 40 seconds, the mass remaining is 3 grams
At time, 50 seconds, the mass remaining is 1.5 grams
Step-by-step explanation:
Given;
initial mass of the radioactive element = 48 grams
half life, t = 10 seconds
time of decay (s) remaining mass of the radioactive element
0 ------------------------------------------------- 48 grams
10------------------------------------------------- 24 grams
20 ------------------------------------------------- 12 grams
30 -------------------------------------------------- 6 grams
40 --------------------------------------------------- 3 grams
50 ----------------------------------------------------- 1.5 grams
60------------------------------------------------------0.75 grams
Thus;
At time, 10 seconds, the mass remaining is 24 grams
At time, 20 seconds, the mass remaining is 12 grams
At time, 30 seconds, the mass remaining is 6 grams
At time, 40 seconds, the mass remaining is 3 grams
At time, 50 seconds, the mass remaining is 1.5 grams

One study found that the number of interest groups increased by what percentage between 1959 and 1995?
Answer:
Percentage change in interest groups between 1959 (500) & 1995 (600) = 20%
Step-by-step explanation:
Percentage change = Change ie (New - Old) x 100
Old value
Suppose -
Number of interest groups in 1959 = 500
Number of interest groups in 1995 = 600
Percentage change = [ (600 - 500) / 500 ] x 100
( 100 / 500 ) x 100 = 20%
What is the perimeter of triangle ABC?
9 + /21 units
O 9 + 29 units
9 + 41 units
9 + 61 units
The perimeter of the triangle ABC is the sum of the side lengths of the triangle
Using the assumed values, the perimeter of the triangle is 12 units
How to determine the perimeter?Assume the side lengths of the triangle are:
AB = 3
BC = 4
CA = 5
Then the perimeter (P) would be:
P = AB + BC + CA
This gives
P = 3 + 4 + 5 = 12
Hence, the perimeter of the triangle is 12 units

Use the following information to find PD and EQ.
AP = 3, PQ = 5, QB = 7, CP=2, and QD = 14
Find PD and EQ
Answer:
[tex] PD = 18 [/tex]
[tex] EQ = 4 [/tex]
Step-by-step explanation:
Given:
AP = 3,
PQ = 5,
QB = 7,
CP = 2,
QD = 14
Required:
1. PD
2. EQ
SOLUTION:
1. Based on Intersecting Chords Theorem,
[tex] AP*PB = CP*PD [/tex]
AP = 3
PB = PQ + QB = 5 + 7 = 12
CP = 2
PD = ?
Plug in the values into the equation
[tex] 3*12 = 2*PD [/tex]
[tex] 36 = 2*PD [/tex]
Divide both sides by 2
[tex] \frac{36}{2} = PD [/tex]
[tex] 18 = PD [/tex]
[tex] PD = 18 [/tex]
b. Based on Intersecting Chords Theorem,
[tex] EQ*QD = AQ*QB [/tex]
EQ = ?
QD = 14
AQ = AP + PQ = 3 + 5 = 8
QB = 7
Plug in the values into the equation
[tex] EQ*14 = 8*7 [/tex]
[tex] EQ*14 = 56 [/tex]
Divide both sides by 14
[tex] EQ = \frac{56}{14} [/tex]
[tex] EQ = 4 [/tex]
