A plumber charges a flat fee of $74 to visit a home and examine a clogged drain. The plumber charges an additional $28 per hour spent fixing the drain. The
total cost, C (in dollars), for fixing a drain that takes h hours is given by the following.
C = 74+28
Answer the following questions.
(a) If the plumber charged a total of $382, how many hours did she spend fixinal

Answers

Answer 1

Answer: A. 74+28(7)=$382

B. 28 hours.

Step-by-step explanation: or b, what you need to do is minus 74 from 382. Then divided by 28.

Answer 2

Answer:

11 hours

Step-by-step explanation:

h = hours

382 = 74 + 28h

subtract 74 from both sides

308 = 28h

h = 11

Check:

382 = 74 +28(11)

382 = 308 + 74

382 = 382

The Nisbets went through the drive through
at the donut shop and spent $10.50 on 2
cups of coffee and 4 donuts. Behind them,
the Roys spent $8.25 on 1 cup of coffee and
5 donuts. What is the cost of one cup of
coffee?

Answers

Answer:

One cup of coffee is $3.25

Step-by-step explanation:

Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut

2c + 4d = 10.5

c + 5d = 8.25

Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4

-10c - 20d = -52.5

4c + 20d = 33

Add them together and solve for c

-6c = -19.5

c = 3.25

So, a cup of coffee is $3.25

Quadrilateral ABCD is inscribed in a

What is the measure of angle A?

(x + 15)

Enter your answer in the box

mZA=

Answers

Answer:

<A = 133degrees

Step-by-step explanation:

Find the diagram attached

Using the theorem that "the sum of opposite angle of a cyclic quadilateral is 180 degrees, hence;

m<A + m<C = 180

4x+5 + x + 15 = 180

4x+x+5+15 = 180

5x+20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32degrees

Get the measure of angle A

<A = 4x+5

<A  = 4(32)+5

<A = 128+5

<A = 133degrees

Find the interest on $6,000 at 5% for 8 months.
A: $200
B: $2,000
C: $240
D: $2,400

Answers

Answer:

A.$200

Step-by-step explanation:

I = PRT/ 100

P = $6000

R = 5%

T = 8 months = 8/12 = 2/3

I = (6000 × 5 × 2/3) /100

I = 20000 / 100

I = $200

If a letter is randomly chosen, what is the probability of choosing the letter A?

Answers

Answer:

it depends on how many letters there are to choose from.

Answer:

if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%

Step-by-step explanation:

There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!

Or if you want to be really specific, 1/26 as a percent is 3.8462%.

The random variable X~(30,2^2)
Find p(X<33)
Find p(X>26)

Answers

Answer:

i) P(X<33)  = 0.9232

ii) P(X>26) = 0.001

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 30

Given that the standard deviation of the Population = 4

Let 'X' be the Normal distribution

Step(ii):-

i)

Given that the random variable  X = 33

               [tex]Z = \frac{x-mean}{S.D}[/tex]

               [tex]Z = \frac{33-30}{2} = 1.5[/tex] >0

P(X<33) = P( Z<1.5)

              = 1- P(Z>1.5)

             = 1 - ( 0.5 - A(1.5))

             = 0.5 + 0.4232

  P(X<33)  = 0.9232

Step(iii) :-

Given that the random variable  X = 26

               [tex]Z = \frac{x-mean}{S.D}[/tex]

               [tex]Z = \frac{33-26}{2} = 3.5[/tex] >0

P(X>26)  = P( Z>3.5)

              = 0.5 - A(3.5)

              = 0.5 - 0.4990

             = 0.001

P(X>26) = 0.001

A list of 5 numbers is shown below.

A integers

C natural numbers

Answers

Answer:

D. Rational Number

Step-by-step explanation:

Integers are defined as all whole numbers, positive and negative, including 0. Since in the list there is a number that is not whole, A is not the correct answer choice.Whole numbers are all positive numbers (including 0) without decimals or fractions. Since the list has a number that is not a whole number, along with two that are negative, B is also not correct.Natural numbers are all positive numbers (excluding 0) without decimals or fractions. Since there is a 0 in the list, C is not correct.Rational numbers are all numbers that can be simplified into a ratio with 2 integers (i.e. π and e are not rational). Since every number on the list can be put into this category, answer choice D is correct.
