The employer will charge $55 for 5 hours

The first step is to calculate the amount charged for an hour

22= 2

x= 1

cross multiply

2x= 22

x= 22/2

x= 11

The amount charged for 5 hours can be calculated as follows

11= 1

y= 5

cross multiply

y= 55

Hence $55 will be charged for 5 hours

To solve an inequality, we need to isolate the value of x, and to do so we will perform a series of calculations in such a way that it remains the inequality unchanged, or at least still true.

To do so, we will perform first a sum of 2x to both sides of it, as follows:

Now, we subtract 3 from both sides:

To finish it, we divide both sides by 2:

In another way, we can express the following:

It means that the solution is option B.

To solve the second part, we need a filled line that comes from the negative infinity and goes until 2, but it must be including the number 2, and for this reason, the correct answer in the second part is:

Answer

B n G = {2}

B u G = {-2, -1 , 0 , 2, 3, 4, 5, 7)

Step-by-step explanation:

Given the following two sets

B = { -2, 2, 3, 5}

G = { -1, 0, 2, 4, 7}

Part A

Find the intersection of B and G

The intersection of two sets is defined as the set of all the elements in set A that is also present in set G

Hence, the set of elements that is present in set B and set G is 2

Mathematically, B n G = {2}

Part B

Find the union of set B and set G

The union of two sets is a set containing all elements that are in both sets B and G

B u G = {-2, -1 , 0 , 2, 3, 4, 5, 7)

Total number of jerseys he have now is 32 jerseys.

A coach has 12 jerseys in beginning. Now, he buys 2 sets of jerseys.

Each set of jerseys have 10 jerseys.

2 set of jerseys have 20 jerseys.

Using unitary method this can also be written as,

1 set ---------------->  10 jerseys

2set ---------------->  20 jerseys

So, total of 20 jerseys are present in 2 sets of jerseys.

Total number of jerseys he have now = 12 jerseys + jerseys in two sets

Total number of jerseys he have now = 12 jerseys + 20 jerseys = 32 jerseys

So we can write, he have total of 32 jerseys now.

Using the normal distribution, it is found that the indicated z-score is Z = 1.08. A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution.

A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.

While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The z-score of a measure X in a normal distribution with mean and standard deviation is given by:

z = (x-μ)/σ,

It counts the number of standard deviations the value deviates from the mean.

We look at the z-score table after determining the z-score to determine the p-value, which is the percentile of X.

We want Z in this problem to have a p-value of 0.8599, thus Z = 1.08.

Step-by-step explanation:

the loan payment on a fixed term mortgage loan of $100,000 at 8% for 30 years will be $ 340,000.

Principal amount = $ 100,000

Interest rate = 8 %

Time period = 30 years.

Now, the interest is simple interest as it is a fixed rate/ fixed term mortgage.

So, the interest will be:

Simple interest = p r t / 100

SI = 100,000 × 8 × 30 / 100

SI = $ 240,000

Amount will be:

A = $100,000 + $ 240,000

A = $ 340,000

Therefore, we get that, the loan payment on a fixed term mortgage loan of $100,000 at 8% for 30 years will be $ 340,000.

STEP BY STEP EXPLANATION:

First, we need to use the graph of f(x) = x^2 which is

Then, if analyze difference between f(x) and g(x), we can see that g(x) = -1*8*f(x)

So, to graph g(x) we have two transformations:

- Multiply f(x) by -1: When we multiply by -1 we obtain the parabola opening down

The domain is the set of x-values and the range is the set of y-values.

A two-variable linear equation is one with the formula ax + by + c = 0.

The solution of the system exists  (1, 1) and (2, 4).

Let the system of Equations be

y = 3x - 2 and y = x²

From these Equations:

x² = 3x - 2,

simplifying the above equation, we get

⇒ x² - 3x + 2 = 0

⇒ x = 1, 2.

Therefore, the value of x exists x = 1, 2.

Answer:

(0, 8) and (-4, 0)

Step-by-step explanation:

Equation is -2x + y = 8

Manipulate this equation so that it becomes a slope-intercept form of equation

To do this:

Add 2x on both sides

-2x + 2x + y = 2x + 8

y = 2x + 8

Once we have this, 2 points which definitely lie on the line are its x and y intercepts

This is the equation of a line with slope = 2 and x-intercept = 8

x-intercept is y-value when x = 0
We can check by plugging in 0 for x in y = 2x + 8

=> y = 2(0) + 8 = 8

=> Point(0, 8) is one of the ordered pairs

Similarly we can find the x-intercept by setting y = 0 and solving for x

Setting y = 0 in y = 2x + 8

=> 0 = 2x + 8

Switch sides

2x + 8 = 0

Subtract 8 from both sides

2x + 8 - 8 = 0 - 8

2x = -8

Divide both sides by 2

=> 2x/2 = -8/2

x = -4

So (-4, 0) is another point on the line

Two ordered pairs are therefore

(0, 8) and (-4, 0)

Step-by-step explanation:

If on January 1, a company purchased new furniture at a cost of $26,000. The furniture is estimated to have a useful life of 5 years and a salvage value of $3200. The  book value of the furniture on December 31 of the first year is: $21,440.

Given data:

Cost = $26,000

Useful life  = 5 years

Salvage value = $3,200

First step is to calculate the  depreciation expenses:

Particular Amount

Cost $26,000

Less: Salvage value ($3,200)

Net cost (a) $22,800

Useful life (b) 5

Depreciation expenses (a/b) $4,560

($22,800 / 5 years)

Second step is to compute the  book value of furniture on 31 Dec of first year:

To determine the book value we would have to deduct the depreciation expenses from the cost.

Particular Amount

Cost of an furniture $26,000

Less: Depreciation ($4,560)

Book value $21,440

Therefore we can conclude that the book value is the amount of $21,440.

The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.

This is a question of percentages.

Given that:-

Price of bouquet of flowers = $ 55

Sales tax % = 6.5 %

Tip % = 15 %

Delivery fee= $10

We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.

Sales tax = (6.5/100)*55 = $3.575

$55 + $3.575 = $58.575

Tip = (15/100)*58.575 = $ 8.78625

Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4
