Ralph jordan recently bought a new lawnmower for 228.00. If he had to pay 6% sales tax on the lawnmower, what wasthe total cost of the lawnmower?A:$251.62
B: 234.00
C:241.68
D:312.42

Answers

Answer 1
Answer: First we find what 6% of 228.00 is.

To do that we would multiply the number by the percent
So 228 x 6 = 1368
Then divide the answer by 100.
1368/100 = 13.68

You can round if you would like but in this case I believe we should leave it alone.

Which means the price was 228.00 and the tax was 13.68 we just have to add them together to find the answer.

228.00 + 13.68 = 241.68

The answer would be C.

A diner makes 26 pizza crusts the first week of summer and 90 pizza crusts each subsequent week. In how many weeks will the total number of pizza crusts made by the pizza parlor be twice the total number of pizza crusts made by the diner?

The total number of pizza crusts made by the pizza parlor will_______

Answers

Answer:

  • Every week

Step-by-step explanation:

Let the number of weeks be x, then equations

Pizza parlor

  • 52 + 180x

Diner

  • 26 +90x

In how many weeks will the total number of pizza crusts made by the pizza parlor be twice the total number of pizza crusts made by the diner?

  • 52 + 180x = 2(26 +90x)
  • 52 + 180x = 52 + 180x
  • 0 = 0

This results means that every week pizza parlor makes twice the number of by diner

Answer:

\large \boxed{\sf always \ be \ double \ than \ the \ diner}

Step-by-step explanation:

Let x  represent the no. of weeks

Pizza parlor:  180x + 52

Diner:  90x  + 26

Write the equation and solve for x

180x + 52 = 2(90x  + 26)

x  = x (TRUE)

The total number of pizza crusts made by the pizza parlor will always be double than the diner.

The probability that a new spark plug is defective is 0.06. You need two new spark plugs. What is the probability that both spark plugs you buy are defective?A) 0.06
B) 0.12
C) 0.0036
D) 0.0030

Answers

Answer:

Option C - 0.0036

Step-by-step explanation:

Given : The probability that a new spark plug is defective is 0.06. You need two new spark plugs.

To find : What is the probability that both spark plugs you buy are defective?

Solution :

Probability of one spark plug being defective is 0.06

We have to find for two defective spark plugs.

This situation is a compound event in which there is more than one possible outcome.

So, The Probability of two spark plug being defective is

P=0.06* 0.06

P=0.0036

Therefore, The Probability of two spark plug being defective is 0.0036.

So, Option C is correct.

Find the surface area of a bar of soap if the diameter is 5 cm and the height is 2cm .

Answers

Please see the pic, I'd solved in it.
Given that:
Diameter = 5 cm
which means,
Radius= (diameter)/(2) = (5)/(2) = 2.5 cm (radius is half the diameter)
and Height = 2 cm
We can assume that the shape is cylindrical 

Formula of the Surface Area of a Cylinder
=2\pir² + 2\pirh
=2\pi(2.5)² + 2\pi(2.5)(2)
=12.5\pi + 10\pi
=22.5\pi cm² (in terms of \pi)
=70.69 cm² ≈ 70.7 cm²

The numbers of days of rain per month in San Diego, for a period of twelve months, are: 7, 7, 7, 5, 2, 1, 0, 0, 1, 3, 4, 6 What is the range of the data values?a. 4
b. 1
c. 7
d. 12

Answers

Hello there, and thank you for posting your question here on brainly.

Short answer: C. 7

Why?

To find the range, we have to take the highest and lowest numbers in the set and subtract them. The highest in the set is 7, and the lowest in the set is 0. Subtract the two. 7 - 0 = 7. 7 is your final answer.

Hope this helped you! ♥

a student was given the equation x^2+6x-13=0 the next step in the students process was x^2+6x+c=13+c state the value of c that creates a perfect square trinomial explain how the value of c is determined

Answers

This is the process of completing the square. 
Keep this equation in mind: ax^2+bx+c
Basically, to make this a perfect square trinomial, you take half of b and square that value. This will make it so you can compress the left side of the equation into (x+b)^2 \ or \ (x-b)^2 depending on the sign in the middle of the original equation.
