Answer:

640 = .8j

640 = 1.15c

Step-by-step explanation:

Let j = cost of Jocelyn's computer

c = cost of Corbin's computer

We know that Adrian's computer costs $640.

Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j

Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c

Answer:

640 = .8j

640 = 1.15c

Step-by-step explanation:

The Mean Absolute Deviation for the following data: 6, 1, 3, 8, 5, 11, 1, 5 is 2.5

The mean absolute deviation of a dataset is the average distance between each data point and the mean.

mean absolute deviation = [tex]\frac{summation|x-mean|}{n}[/tex]

where

Therefore, let's calculate the mean first.

Arrange the data in ascending order.

1, 1, 3, 5, 5, 6, 8, 11

mean = 1 + 1 + 3 + 5 + 5 + 6 + 8 + 11 / 8 = 40 / 8 = 5

Therefore, let's calculate the distance between each dat point and mean.

|1 - 5| + |1-5| + |3-5| + |5-5| + |5-5| + |6-5| + |8-5| + |11-5|

4 + 4 + 2 + 0 + 0 + 1 + 3 + 6 = 20

Answer:

x = 12°

Welcome to concept of Inscribed Angle theorem

In the diagram shown above, the inscribed angle m∠SUT intercepts the diameter ST.

Then,

m∠SUT = 90°

In Δ SUT,

m∠S + m∠U + m∠T = 180°

Substitute.

m∠S + 90° + 43° = 180°

m∠S + 133° = 180°

Subtract 133° from each side.

m∠S = 47°

m∠UST = 47°

By Inscribed Angle Theorem,

m∠arc UT = 2 ⋅ m∠UST

Substitute.

(9x - 14)° = 2 ⋅ 47°

(9x - 14)° = 94°

9x - 14 = 94

Add 14 to each side.

9x = 108

Divide each side by 9

x = 12

Hence, we get as x = 12°

Answer:

a) x = 9.

b) y = 61.

Step-by-step explanation:

As the 2  weighing scales balance:

4 + 4x = 31 + x

3x = 31 - 4 = 27

x = 9.

Also 4 + 4x + x + 31  = y + 2x + 1

Substituting  for x:

4 + 4(9) + 9 + 31 = y + 2(9) + 1

80 = y + 19

y = 80 - 19 = 61.

Answer:

x = 9

y = 61

Step-by-step explanation:

The main scales are balanced.

The left side of the main scales comprises another scale, which is also balanced.

From this and the values given, we can construct two equations.

Equation 1

Balancing the scales on the left of the main scales:

⇒ 4 + 4x = 31 + x

Solving this for x:

⇒ 4 + 4x - 4 = 31 + x - 4

⇒ 4x = 27 + x

⇒ 4x - x = 27 + x - x

⇒ 3x = 27

⇒ 3x ÷ 3 = 27 ÷ 3

⇒ x = 9

Equation 2

Balancing the main scales:

4 + 4x + 31 + x = y + 1 + 2x

Rearranging to make y the subject:

⇒ 5x + 35 = y + 1 + 2x

⇒ 5x + 35 - 1 = y + 1 + 2x - 1

⇒ 5x + 34 = y + 2x

⇒ 5x + 34 - 2x = y + 2x - 2x

⇒ 3x + 34 = y

Substituting the found value of x (from Equation 1) and solving for y:

⇒ y = 3(9) + 34

⇒ y = 27 + 34

⇒ y = 61

Finding volume :

Answer: 448 cm³

Step-by-step explanation:

    Volume of a triangle prism can be found with;

V = [tex]\frac{1}{2}[/tex] * W * L * H

V = [tex]\frac{1}{2}[/tex] * W * L * H

V = [tex]\frac{1}{2}[/tex] * 8 cm * 14 cm * 8 cm

Answer:

center = (-2, 6)

radius = 6

Step-by-step explanation:

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where (a, b) is the center and r is the radius)

Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.

Given equation:

[tex]x^2+y^2+4x-12y+4=0[/tex]

Collect like terms and subtract 4 from both sides:

[tex]\implies x^2+4x+y^2-12y=-4[/tex]

Complete the square for both variables by adding the square of half of the coefficient of [tex]x[/tex] and [tex]y[/tex] to both sides:

[tex]\implies x^2+4x+\left(\dfrac{4}{2}\right)^2+y^2-12y+\left(\dfrac{-12}{2}\right)^2=-4+\left(\dfrac{4}{2}\right)^2+\left(\dfrac{-12}{2}\right)^2[/tex]

[tex]\implies x^2+4x+4+y^2-12y+36=-4+4+36[/tex]

Factor both variables:

[tex]\implies (x+2)^2+(y-6)^2=36[/tex]

Therefore:

The cost in dollars of making x items is given by the function C(x) = 10x + 900. The fixed cost is 900 dollars. C(25 ) = $1150. The Range is 250.

The function is a type of relation, or rule, that maps one input to specific single output.

The cost in dollars of making x items is given by the function

C(x) = 10x + 900

a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.

The fixed cost

C(0) = 10(0) + 900

       = 0 + 900

       = $900

b. What is the cost of making 25 items?

C(25) = 10(25) + 900

       = 250 + 900

       = $1150

Therefore, C(25 ) = $1150

c. Suppose the maximum cost allowed is $1900. What are the domain and range of the cost function, C(x)?

The domain is the set of values for which the given function is defined.

Range = Maximum value of the data set - Minimum value of the dataset

Range = C(25 ) - C(0)

           = 1150 - 900

Answer: D. "Number graph ranging from negative three to three on the x axis and negative two to four on the y axis. A line is drawn on the graph that passes through the points (negative one, zero) and (zero, four)."

Step-by-step explanation:

We know that our graph passes through two given sets of points, therefore we can plug in those points to find the correct answer.

Let's test it with choice A. It gives us the points (0,-6) and (3,0). We can plug these into the equation to see if it is true. y-4 = 2(x+1) becomes
-6-4 = 2(3+1), or -10 = 8 which is not true, so we can eliminate it.

Choice B gives us (0,-4) and (1,0) -4-4 = 2(0+1) or -8 = 2, this one is wrong.

Choice C gives us (-1,0), so 0-4 = 2(-1+1) or -4 = 0, this one is also wrong.

Choice D gives us (-3,0) so 0-4 = 2(-3+1) or -4 = -4. This is the only option which has a correct solution, and therefore it is your answer.
