The consumer's surplus at the unit price p = 10 for the given demand equation is $45.00, which represents the area between the demand curve and the price line up to the quantity demanded.
To calculate the consumer's surplus at the unit price p for the demand equation q = 120 - 2p, we need to find the area under the demand curve up to the price p. In this case, the given unit price is p = 10.
First, we need to find the quantity demanded at the price p. Substituting p = 10 into the demand equation, we get:
q = 120 - 2(10) = 120 - 20 = 100
So, at the price p = 10, the quantity demanded is q = 100.
Next, we can calculate the consumer's surplus. Consumer's surplus represents the difference between what consumers are willing to pay and what they actually pay. It is the area between the demand curve and the price line.
To find the consumer's surplus, we can use the formula:
Consumer's Surplus = (1/2) * (base) * (height)
In this case, the base is the quantity demanded, which is 100, and the height is the difference between the highest price consumers are willing to pay and the actual price they pay. The highest price consumers are willing to pay is given by the demand equation:
120 - 2p = 120 - 2(10) = 120 - 20 = 100
So, the height is 100 - 10 = 90.
Calculating the consumer's surplus:
Consumer's Surplus = (1/2) * (100) * (90) = 4500
Rounding the answer to the nearest cent, the consumer's surplus at the unit price p = 10 is $45.00.

Given right triangle abcabc with altitude \overline{bd} bd drawn to hypotenuse \overline{ac} ac. If ac=16ac=16 and dc=4,dc=4, what is the length of \overline{bc}? bc ?.
The length of bc is 8. The result is obtained by using the concept of conditions for similar triangles.
How are the conditions for similar triangles?For two or more similar triangles, it has two conditions.
Corresponding angles of the triangles are equal.Corresponding sides of the triangles are in proportion to each other.A right triangle abc with altitude bd drawn to hypotenuse ac has the length of sides as follow
ac = 16dc = 4Find the length of bc!
Observe the picture of triangles in the attachment! If we drawn a perpendicular line to the hypotenuse, we'll have three similar triangles.
The corresponding sides of the two triangles are
\(\frac{\overline{ac}}{\overline{bc}} = \frac{\overline{bc}}{\overline{dc}} = \frac{\overline{ab}}{\overline{bd}}\)
The length of bc is
\(({\overline{bc})^{2} = \overline{ac} \times {\overline{dc}\)
\(({\overline{bc})^{2} = 16 \times 4\)
\(({\overline{bc})^{2} = 64\)
\({\overline{bc} = \sqrt{64}\)
\({\overline{bc} = 8\)

suppose a drug is known to have mild side effects in 75% of the people who take it . it is administered to 100 people. using the binomial distribution, find the probability that more than 70 people will experience mild side effects
Let X be the number of people who experience mild side effects after taking the drug. X follows a binomial distribution with parameters n = 100 (the number of people taking the drug) and p = 0.75 (the probability of mild side effects).
To find the probability that more than 70 people will experience mild side effects, we need to calculate:
P(X > 70) = 1 - P(X ≤ 70)
Using the cumulative distribution function (CDF) of the binomial distribution, we can find:
P(X ≤ 70) = F(70) = ∑(i=0 to 70) [nCi * p^i * (1-p)^(n-i)]
where nCi is the binomial coefficient for choosing i items out of n.
We can use a software or calculator to calculate this sum, or use an approximation like the normal approximation to the binomial distribution.
Assuming normal approximation is appropriate, with mean μ = np = 75 and standard deviation σ = sqrt(np(1-p)) = 3.354, we can calculate the z-score:
z = (70.5 - μ) / σ = (70.5 - 75) / 3.354 = -1.33
Using a standard normal distribution table or a calculator with normal distribution functions, we can find the probability of z-score less than -1.33 is 0.0918, which is the probability of 70 or fewer people experiencing mild side effects.
Therefore, the probability of more than 70 people experiencing mild side effects is:
P(X > 70) = 1 - P(X ≤ 70) = 1 - 0.0918 = 0.9082
Using the binomial distribution, there is a probability of approximately 0.9082 that more than 70 people will experience mild side effects out of 100 people who take the drug.

bill invested some money at 5% annual interest, and Janette invested some at 7%. If thier combined interest was $310 on a total investment of 5,000, how much did bill invest?
Bill invested $2000 at 5% annual interest
How to determine how much Bill invested?
To solve for the word problem, you need to set up two equations.
Let B and J represent how much Bill and Janette invested respectively
The interest of 5% = 5/100 = 0.05 and 7% = 7/100 = 0.07
Based on the given info, we can write that:
J + B = 5000 --- (1)
0.05B + 0.07J= 310 --- (2)
From (1):
J = 5000 - B --- (3)
Put (3) in (2):
0.05B + 0.07(5000 - B) = 310
0.05B + 350 - 0.07B = 310
-0.02B = 310-350
-0.02B = -40
0.02B = 40
B = 40/0.02
B = $2000
Thus, Bill invested $2000

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

ALSO PLEASE PLEASE HELP ME
Answer:
Hi there!
Recall that slope-intercept form is:
y = mx + b
Where m = slope
In this instance, we are given a slope of 4,
therefore:
y = 4x + b
Substitute in the x and y coordinates of the point given:
0 = 4(3) + b
0 = 12 + b
Substract 12 from both side:
-12 = b
Therefore, the equation would be:
y = 4x - 12
Graph the equation by finding x and y values or using a calculator:
x = 0, y = 4(0) - 12 = 12 (0, 12)
x = 1, y = 4(1) - 12 = - 8 (1, -8)
x = 2, y = 4(2) - 12 = - 4 (2, -4)
x = 3, y = 4(3) - 12 = 0 (3, 0)

Step-by-step explanation:
a cubic box is completely filled with 2650 g of water. what is the length of one side of the box, in meters?
The length of one side of the box, in meters, is 0.138 meters.
The density of water is approximately 1000 kg/m^3 or 1 g/cm^3. If a cubic box is filled with 2650 g of water, we can find the volume of the box and then find one side length.
Volume = Mass / Density = 2650 g/(1 g/cm^3) = 2650 cm^3
Since the box is cubic, one side length is the cube root of the volume.
Side length = (Volume)^(1/3) = (2650 cm^3)^(1/3) = 13.8 cm
To convert cm to meters, divide by 100:
Side length = 13.8 cm/100 cm/m = 0.138 m

It would take 12 men 18 days to complete the job.
1) g ∝ h
g = kh; where k is the constant of variation.
g = 64, h = 8, hence:
64 = 8k
k = 8
g = 8h
2) j ∝ 1/h
j = k/h; where k is the constant of variation.
j = 190, h = 7, hence:
190 = k/7
k = 1330
j = 1330/h
When h = 70:
j = 1330/70
j = 19
3) y represent number of men and x represent the days
y ∝ 1/x
y = k/x
9 = k/24
k = 216

The measures of angles 4 and 5 are:

How to find the measures of the angles?On the image we can see that angles 1 and 2 are next to eachother, that means that the sum of their measures must be a plane angle, that is an angle of 180°.
Then we can write the sum:
∠1 + ∠2 = 180°
(3x + 5) + (2x + 10) = 180
5x + 15 = 180
5x = 180 - 15
x = 165/5 = 33
the measure of angle 5 is the same one of angle 1 then:
∠5 = (3*33 + 5)° = 104°
And angle 4 is supplementary of angle 1, then:

What is the linear distance traveled in one revolution of a 36-in diameter wheel.
The linear distance traveled in one revolution of a wheel can be calculated using the formula:
Circumference = π * Diameter
Given that the diameter of the wheel is 36 inches, we can substitute the value into the formula:
Circumference = π * 36 inches
Using an approximate value of π as 3.14159, we can calculate the circumference:
Circumference ≈ 3.14159 * 36 inches
Circumference ≈ 113.09724 inches
Therefore, the linear distance traveled in one revolution of a 36-inch diameter wheel is approximately 113.09724 inches.

Find the sum of the interior angles for a hexagon. 540° 720° 900° 1,080°
The sum of interior Angles of Hexagon is always 720°
Any hexagon's internal angles add up to 720° in all cases. By dividing 720° by 6, we may get the size of each interior angle of a regular hexagon. As a result, we have:
720°÷6 = 120°
In a regular hexagon, each inside angle is 120°.
An example of a regular hexagon with equal-length sides and angles is shown in the diagram below. By multiplying the six 120° angles together, we can demonstrate that the result is 720°.
Therefore, the interior angles of a hexagon are always added up to 720°.
