Based on the information, we can infer that the salary a worker earns depends on the hourly wage they earn. In this case we will have to multiply the value of each hour by the number of hours worked. Additionally, I would agree to have a higher minimum wage to benefit workers.

Based on the information in the graph, we can infer that workers will have wages of $5.2, $6.0, and $6.6. According to the above, the salary varies depending on the number of hours.

On the other hand, I believe that you would agree to a salary increase because this would benefit workers who would be better paid for each hour of work.

Step-by-step explanation:

The ordered triple representing \(3u - 2v\) is \((13, -8, 5)\).

To find an ordered triple representing \(3u - 2v\),

where \(u = (5, -2, 3)\) and \(v = (1, 1, 2)\),

we can perform the following operations:

\(3u = 3(5, -2, 3)\)

\(3u = (15, -6, 9)\)

\(2v = 2(1, 1, 2)\)

\(2v = (2, 2, 4)\)

Now, subtracting 2v from 3u gives:

\(3u - 2v = (15, -6, 9) - (2, 2, 4)\)

\(3u - 2v = (15-2, -6-2, 9-4)\)

\(3u - 2v = (13, -8, 5)\)

Therefore, the ordered triple representing 3u - 2v is (13, -8, 5).

Side Q'S' lies on a line with a slope of -1.

The distance from Q' to the origin is twice the distance from Q to the origin.

Step-by-step explanation:

The explanations are as follows

As we can see from the attached figure that the ΔQ'R'S' is dilated i.e transformation is made or change in size

Now

Based on

(x,y) = (2x,2y)

The intercepts are as follows

For S

(-1,1)  = (-2,2)

For Q

(-3,3) = (-6,6)

For S

(2,4) = (4,8)

Step-by-step explanation:

Answer: x = 56

Step-by-step explanation:

The two angles 'z' and 124 add up to form a straight line. The angle of a straight line is 180 degrees. Therefore, we can say that:

\(z+124=180\)

Subtract 124 on both sides to isolate the angle 'z' to get:

\(z=56\)

Answer:

z=56 degrees

Step-by-step explanation:

in total the line will equal 180 so just do 180-124 and you get 56.

Answer:

Step-by-step explanation:

In the question we have given volume of Sphere that is 562.5 π in³ and we have asked to find the radius of given sphere. We know that the volume of sphere ,

\( \blue{ \boxed{ \rm{Volume \: of \: Sphere = \frac{4}{3} \pi r {}^{3} }}}\)

So equating it with given volume for finding the radius of sphere :

\( \longmapsto \: \frac{4}{3} \pi r{}^{3} = 562.5\pi\)

Step 1 : Cancelling π as it was present in both side :

\(\longmapsto\:\frac{4}{3} \cancel{\pi }r{}^{3} = 562.5 \cancel{\pi}\)

Step 2 : Transposing 4/3 to right hand side :

\(\longmapsto \: r {}^{3} = 562.5 \times \frac{3}{4} \)

Step 3 : Multiplying 562.5 with 3 :

\(\longmapsto \:r {}^{3} = \frac{1687.5}{4} \)

Step 4 : Dividing 1687.5 by 4 :

\(\longmapsto \:r {}^{3} = 421.875\)

Step 5 : Finding cube root of 421.875

\(\longmapsto \:r = \sqrt[3]{421.875} \)

Step 6 : We get :

\(\longmapsto \: \red{ \boxed{r = 7.5}}\)

Answer:

Step-by-step explanation:

A) Commission = 2450 shillings * 25 % = 2450 shillings * (25/100) = 2450 shillings * (0.25) = 612.50 shillings

Commission = 612.50 shillings

B) If the total sale is 2,450.00 shillings, after the seller gives buyers a 2% discount. We must re-enter the discount:

2,450.00 shillings = X - X * 2% = X - 0.02 X --->

------> 0.98 X = 2,450.00 shillings

------>X= 2,450.00 / 0.98

------> X = 2,500.00  shillings

NEW COMMISSION = 2,500.00 shillings * 25 % = 2,500.00 shillings *(25/100) =2,500.00 shillings * (0.25) = 625 shillings

NEW COMMISSION = 625 shillings

Answer:

Step-by-step explanation:

A= New amount

P= Principal or Original amount which is £1500

I= Interest

t= time period

3.5% as a decimal is 3.5÷100=0.035

time period= 4 years

so 1500(1+0.035)^4 = B

The height should you drop an object in order for it to have a velocity of 80 ft/sec is: 99.4 feet.

V = √2ha

80=√2(h)32.2

80²=√2(t) (32.2)²

6400=2(t) (32.2)²

Divide both sides by 32.2 to get 2t

6400/32.2=2(t) (32.2)/32.2

198.75776397=2(t)

Divide both sides by 2 to get t

198.75776397/2=2(t)/2

Hence,

99.4 feet

Therefore the height should you drop an object in order for it to have a velocity of 80 ft/sec is: 99.4 feet.

Answer: ∠16 and ∠11

Step-by-step explanation:

      All of these answer options include ∠16, so we know we're looking for an angle that is corresponding to ∠16. A corresponding angle is an angle that is in the same relative position. We will look at ∠9, ∠11, ∠2, and ∠12 since those are the given answer options, and see which is corresponding.

The correct corresponding angles are ∠16 and ∠11.

The final velocity of the parameters is 13.5m/s

In this question, the given parameters are represented as

Formula: v = u + at

Initial velocity = 3m/s

Acceleration = 1.5m/s²

Time = 7 seconds

When these parameters are represented using their required notation, we have the following representations

u = 3m/s

a = 1.5m/s²

t = 7 s

Next, we substitute the above parameters in the above equation

So, we have the following representation

v = 3 + 1.5 * 7

Evaluate the products

This gives

v = 3 + 10.5

Evaluate the sum

So, we have the following representation

v = 13.5

The notation v represents the final velocity

Hence, the final velocity is 13.5m/s

Answer:

slope (m) = 2/3

Step-by-step explanation:

slope = change in x /change in y

Also, slope is y2 - y1 / x2 -x1. That is what I apply for this activity, hence:

slope = 3 - (-1) / 0 - (-6)

         = 3 + 1 / 0 + 6

         = 4 / 6

         = 2/3

∴ slope(m) = 2/3
