A plumber charges a service charge of $20 plus $15 per one-half hour of work. the cost to hire the plumber is given by the function f(x) = 15x + 20, in which f(x) represents the cost and x represents the number of one-half hours the plumber works. If the Jackson family has $200 to spend on the water leak repair, what is the maximum number of hours the plumber can work to repair the leak?

Answer:

9

Step-by-step explanation:

(3/2)^3 = 27/8

27/8 x 8/3 = 27/3 = 9

Answer:

8 nickels=.40

15 dimes=1.50

The number of dimes is 15 and the number of nickels is 8.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A container has 23 coins comprising dimes and nickels. The aggregate sum of cash is $1.90.

Let d be the number of dimes and n be the number of nickels. Then the equation is given as,

d + n = 23                           ...1

0.1d + 0.05n = 1.90            ...2

From equations 1 and 2, then we have

0.1(23 - n) + 0.05n = 1.90

2.3 - 0.1n + 0.05n = 1.9

0.05n = 0.4

n = 8

Then the number of dimes is given as,

d + 8 = 23

d = 23 - 8

d = 15

The number of dimes is 15 and the number of nickels is 8.

The required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of adult tickets is x and the number of children's tickets be y,
According to the quesiton,
The tickets cost $5.00 for adults and $2.00 for children. He sold 200 tickets and collected $610.

So equaiton models as,
x + y = 210
5x + 2y = 610

Thus, the required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.

Answer:

27 Feet is the answer. Option C.

The flagpole is 27 feet tall.

"It is a triangle whose one of the angle measures 90° "

For angle [tex]\theta[/tex], [tex]tan(\theta)=\frac{opposite ~side~of~angle~\theta}{adjecent~side~of~angle~\theta}[/tex]

"An angle that is formed between the horizontal line and the line of sight. "

For given question,

Consider the following diagram.

Here, AB = the flagpole,

A flagpole casts a 40-foot shadow.

so, BC = 40 foot

The angle of elevation from the tip of the shadow to the tip of the flagpole is 34°.

⇒ ∠ACB = 34°

We need to find the height of the flagpole.

We find the tan of angle 34°

[tex]\Rightarrow tan(34)=\frac{AB}{BC}\\\\ \Rightarrow 0.6745=\frac{AB}{40}\\\\\Rightarrow AB=0.6745\times 40\\\\\Rightarrow AB = 26.98\\\\\Rightarrow AB\approx 27~feet[/tex]

Therefore, the flagpole is 27 feet tall.

Step-by-step explanation:

5, 11, 18, 26,

The difference between 5 and 11 is 6.

The difference between 11 and 18 is 7.

The difference between 18 and 26 is 8.

As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.

26 + 9 = 35

And the next difference would be 9 + 1 = 10.

35 + 10 = 45
