5. -W=28
1. W= -4

Answer:

78°

Step-by-step explanation:

(I'm assuming that segment AB is a straight line {180 degrees})

1. since angles DCA and DCB equals 180°, we can set up the equation 4x+2+3x+3=180.

2. if you solve that, you'll get x=25.

3. plug 25 (x) into 3x+3 -> 3(25)+3

4. 3(25)+3=78

5. answer: 78°

Answer:

number of large year book sold = 380

number of small year book sold =520

Step-by-step explanation:

Let the no. of large year book pages be x

given that

cost of 1 large year book = $4

cost of x large year book = x*cost of 1 large year book = $4x

Let the no. of small year book pages be y

given that

cost of 1 small year book = $2.5

cost of y small year book = y*cost of 1 large year book = $2.5y

also,

total year books sold were 900

no. of small year book + no. of small year book = 900

x + y = 900

y = 900 - x  ------------------>1

also total money made by selling large and small year book = $2820

cost of x small year book + cost of x large year book = 2820

4x + 2.5y = 2820

using y = 900 - x in above equation

4x + 2.5(900-x) = 2820

4x + 2250 - 2.5x = 2820

1.5x = 2820-2250 = 570

x = 570/1.5 = 380

Thus,

number of large year book sold = 380

number of small year book sold = 900-380 = 520

1. C. The managers used a cluster sample

2.  B)The managers used a systematic sample.

3. The managers used a stratified sample.

Step-by-step explanation:

1. In a cluster sampling method, the population would be divided into several small units called cluster by the researcher. Within these clusters we randomly pick one or more to observe.

2. In systematic sampling we select elements from an ordered sampling frame.

3. In stratified sampling, the population is divided into several stratas and the researcher then selects randomly to complete the sampling process

Answer:

[tex]y=\frac{1}{7}x-\frac{6}{7}[/tex]

Step-by-step explanation:

Two points (1, -1) and (0, 6) are lying on the given line.

Rule to find the coordinates of a point by the rotation of 90° clockwise is,

(x, y) → (y, -x)

Therefore, image points of (1, -1) and (0, 6) will be,

(1, -1) → (-1, -1)

(0, 6) → (6, 0)

Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (-1, -1) and (6, 0) will be,

m = [tex]\frac{0+1}{6+1}[/tex] = [tex]\frac{1}{7}[/tex]

Equation of the line passing through (6, 0) and slope = [tex]\frac{1}{7}[/tex]

y - y' = m(x - x')

y - 0 = [tex]\frac{1}{7}(x - 6)[/tex]

[tex]y=\frac{1}{7}x-\frac{6}{7}[/tex]

Third choice. 9/14

Step-by-step explanation:

Answer:

100 joules/ second

Step-by-step explanation:

5,000/50 seconds = 100 joules/ second

If a light bulb that consumed 5000 joules in 50 seconds, then the unit rate at which this light bulb used energy is, 100 joules/seconds or 100 watts.

Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

Given that,

A light bulb that consumed 5000 joules in 50 seconds,

The unit rate at which this light bulb used energy = ?

To find the unit rate,

we can divide the energy consumed (in joules) by the time it took to consume that energy (in seconds):

Unit rate = 5000/50 joules/seconds

              = 100 Watts

Note: 1 Watt = 1 Joule/second,

so the unit rate can also be expressed as joules per second.

Hence, the unit rate at which the light bulb used energy is 100 Watts.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The value of Tan(B) will be equal to 8/15.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

The value of Tan(B) will be the ratio of the sides AC and BC. Therefore, the value of Tan(B) can be written as,

Tan(B) = AC / BC

Tan(B) = 8/15

Hence, the value of Tan(B) will be equal to 8/15.

Answer:

C.) False, counterexample of 15

1) 15 is divisible by 3 but not by 6
