Answer:

d) 189.3 in²

Step-by-step explanation:

Area of rectangle is,

→ w × l

→ 10 × 15

→ 150 in²

Area of semi circle is,

→ (1/2)πr²

→ (1/2) × 3.14 × (5)²

→ 1.57 × 25

→ 39.3 in²

Now the total area will be,

→ 150 + 39

→ 189.3 in²

Thus, total area is 189.3 in².

Answer:

0.25x+1.75

Step-by-step explanation:

A linear equation is of the form ax+b. Set a up a system of equation with -3 and 13 substituted in to ax+b. We get -3a+b=1 and 13a+b=5. Solving tis gives us a,b=(0.25,1.75)

Answer:

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

a linear function has the form

f(x) = ax + b ( a and b have to be found )

given f(- 3) = 1 and f(13) = 5 , then by substitution

- 3a + b = 1 → (1)

13a + b = 5 → (2)

subtract (2) from (1) term by term to eliminate b

- 3a - 13a = 1 - 5

- 16a = - 4 ( divide both sides by - 16 )

a = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]

substitute a = [tex]\frac{1}{4}[/tex] into (1) and solve for b

- 3( [tex]\frac{1}{4}[/tex] ) + b = 1

- [tex]\frac{3}{4}[/tex] + b = 1 ( add [tex]\frac{3}{4}[/tex] to both sides )

b = 1 [tex]\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex] ← is the linear function

or

f(x) = 0.25x + 1.75

[tex]\textit{area of a rectangle}\\\\ A=Lw ~~ \begin{cases} L=length\\ w=width\\[-0.5em] \hrulefill\\ A=12\sqrt{30}\\ w=3\sqrt{5} \end{cases}\implies 12\sqrt{30}=L3\sqrt{5}\implies \cfrac{12\sqrt{30}}{3\sqrt{5}}=L \\\\\\ 4\cdot \cfrac{\sqrt{30}}{\sqrt{5}}=L\implies 4\cdot \sqrt{\cfrac{30}{5}}=L\implies 4\sqrt{6}=L[/tex]

The total amount remaining after the deduction of $14.5 from $290.34 is $275.823.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Lisa Steamer is married, earns $290.34 weekly as a receptionist, and claims no allowances.

As we know that there will be a 5% of deduction of tax,

Calculate the amount after the tax deduction,

Amount  = 5 / 100 × $290.34

Amount = $14.5

The remaining amount after tax deduction = 290.34 - 14.5 = $275.823

Therefore, the total amount remaining after the deduction is $275.823.

The complete question is:

Lisa Steamer is married, earns $290.34 weekly as a receptionist, and claims no allowances. Find the total amount after deduction.

Since Anthony is 30, the largest amount he can contribute and deduct from his Form W-2 for the traditional IRA for 2021 is $6,000.

The traditional IRA or individual retirement account is a pre-tax contribution an employee saves towards retirement.

With a traditional IRA, Anthony can contribute pre- or after-tax dollars, allowing his savings to grow tax-deferred while withdrawals are taxed as current income unless after the age of 59½.

An additional tax of 10% may apply if Anthony withdraws from his traditional IRA before reaching 59½ years.

However, one advantage of the traditional IRA is that the employee invests more funds upfront since the deduction is mostly made before tax.

Thus, I will advise Anthony to deduct a maximum of $6,000 from Form W-2 towards his traditional IRA to save more money in advance.

If Ezra decides to also spend more than $80 on a printer, that is, the amount spent on a printer is greater than $80

Adding an amount greater than $80 to the inequality,

It becomes 15x + 10y > 1180

The linear function that shows the proportional relationship between the distance and time is d = 100t

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,

From the table given, we can find the slope of the function by using the formula

m = y₂ - y₁ / x₂ - x₁

m = 300 - 200 / 3 - 2

m = 100

To find the y - intercept,

y = mx + c

300 = 100(3) + c

300 = 300 + c

c = 300 - 300

c = 0

The equation that shows the relationship is

The domain of the equation is 10 days and the range is the $14 left in the account.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

a) The independent variable in this problem is the number of days, represented as x. The amount of money left, the y variable is the dependent variable since it depends on the number of days left (x).

b) If there are 10 days left, we can plug it into the given equation to find the balance in the account.

y = -3x + 44                    

y = -3(10) + 44                

y = -30 + 44                    

y = 14                              

Hence, the domain of the equation is 10 days and the range is the $14 left in the account.

2. x = 1

Some properties of parallelogram we need to recall in  order to solve the problem given are:

1. q = 1x + 10

AC = 7x + 8

Therefore:

q = 1/2(AC) [based on the property of a parallelogram]

Substitute

x + 10 = 1/2(7x + 8)

Solve for x

2(x + 10) = 7x + 8

2x + 20 = 7x + 8

2x - 7x = -20 + 8

-5x = -12

x = -12/-5

x = 2.4

Length of AC = 7x + 8 = 7(2.4) + 8

Length of AC = 24.8 units

2. x + 8 = 7x + 2 [based on the property of a parallelogram]
