A circular plate has a diameter of 11 inches. An ant walking along the edge makes 1.5 revolutions in 4
minutes. Approximately how many inches does the ant travel in one minute? Round your answer to the
nearest tenth of an inch.

Answers

Answer:

[tex]12.95 \: inches[/tex]

Step-by-step explanation:

We were told that the diameter of the circular plate is 11 inches. In order to find the distance the ants travel to make one revolution we have to first find the circumference of the circular plate. Circumference is:

[tex]2\pi \: r[/tex]

The radius would be half of the diameter (11). Therefore the radius is 5.5.

[tex]r = 5.5 \: \: \: \: \: \pi = 3.14 \\ cir = 2(3.14) \: (5.5) \\ cir = 6.28 \times 5.5 \\ cir = 34.54[/tex]

Since we found the circumference of the circular plate that means that we know how much one revolution made by the ants would be (34.54). Since the ant made 1.5 revolutions we have to multiply 34.54 by 1.5.

[tex]34.54 \times 1.5 = 51.81[/tex]

So we now know that the ant walked 51.81 inches in 4 minutes, now we have to find the distance he would walk in 1 minute.

Let x be the unknown value*

[tex] 51.81 \:inches = 4 \:minutes \\ x \:inches = 1 \: minutes\\ \\ 51.81=4x \\ \\\frac{51.81}{4} = x \\ \\ 12.95 = x[/tex]

Answers

Answer: 71/28 or 2 15/28

Step-by-step explanation:

Turn both fractions into improper fractions.

5 1/4 = 21/4

2 5/7 = 19/7 multiply the denominator with the whole then add the numerator, same denominator.

21/4 - 19/7 = ? find common denominator to subtract

4 x 7 = 28 common denominator

Divide the new denominator by previous denominators then multiply by each respective numerator. 28 divided by 4 is 7 multiplied by 21 is 147, the same happens with 19/7.

147/28 - 76/28 = 71/28 or 2 15/28

Two cheeseburgers and one small order of fries contain a total of 1320 calories. Three cheeseburgers and two small orders of fries contain a total of 2170 calories. Find the caloric
content of each item.

Answers

Answer:

cheeseburger: 470 caloriesfries: 380 calories

Step-by-step explanation:

The given relations let you formulate two equations in the two unknown values. These can be solved by any of the usual methods.

setup

Let x represent the caloric content of a cheeseburger, and y the caloric content of a small order of fries. The problem statement tells us ...

2x +y = 1320

3x +2y = 2170

solution

Subtracting the second equation from twice the first gives ...

2(2x +y) -(3x +2y) = 2(1320) -(2170)

x = 470

Using the first equation, we can find y:

y = 1320 -2x = 1320 -2(470) = 380

A cheeseburger has 470 calories; a small order of fries, 380 calories.

When Abigail had one cat, she needed to serve 2 cans of cat food each day. Now that Abigail
has adopted a second cat, she needs to serve a total of 3 1/2 cans each day. How much extra
food is needed to feed the second cat?
Write your answer as a fraction or as a whole or mixed number.
cans

Answers

Based on the information provided, to feed the second cat it is necessary 1 1/2 extra cans or 1.5 cans.

How much extra food is needed to feed the second cat?

This difference can be found by substracting the total cans fed with only one cat to the total fed with two cats:

3 1/2 cans - 2 cans = 1 1/2 cans, which can also be expressed as 1.5 cans.

Based on this, to have a second cat implies 1.5 extra cans.

(URGENT) Maurice and Rhonda a are traveling in the same direction along the same road. Maurice is traveling at 55 mph and is exactly 15 miles ahead of Rhonda, who is traveling at 65 mph. How many hours will it take Rhonda to catch Maurice?

Answers

Answer:

Step-by-step explanation:

Givens

Maurice

55 miles an hour

15 miles ahead of Rhonda

Rhonda

65 miles per hour

The distance has to be the same for both in order to meet.

Formula

d1 = d2

d = r * t where r is the speed.

65*t = 55t + 15 Subtract 55t from both sides

Solution

65t - 55t = 55t - 55t + 15 Combine

10t = 15 Divide both sides by 10

10t/10 = 15t/10

t = 1.5 hours

Answer

They will meet in 1.5 hours.

Can someone please help I’m stuck ( and please show the work) thank you.

Answers

Event=200 or more cars

The number of cars was counted on 10 days and thus there were 10 trials.

# of trials=10

200 or more cars were counted on 9 of the 10 days and thus the event occurs 9 times.

# of times the event occurs= 9

The probability is the number of times the event occurs divided by the number of trials:

P ( 200 or more cars)= # of times the event occurs / # of trials

=9/10
0.9
90%

We know that the sum Of the probabilities Of an event And it’s Complement needs to be equal to 1.

P( event ) + P ( complement)= 1

What is it is “200 or more cars”

P( 200 or more cars) + P (not 200 or more cars) = 1

Since P ( 200 or more cars) = 9/10 we can replace P ( 200 or more cars) in the equation by 9/10

9/10 +P ( not 200 or more cars) =1

Subtract 9/10 from each side

-9/10= 1-9/10

Combine like terms

P( not 200 or more cars) = 1/10= 0.1 = 10%

A: 9/10 = 0.9 = 90%
B: 1/10= 0.1= 10%

What are the solutions of this quadratic equation? 6x2 6 = 12x 18 a. b. c. d.

Answers

The solution to the quadratic equation 6x² + 6 = 12x is x = 1

How to determine the solutions?

The quadratic equation is given as:

6x² + 6 = 12x

Equate the equation to 0

6x² - 12x + 6 = 0

Expand the equation

6x² - 6x - 6x + 6 = 0

Factorize the expression

6x(x - 1) - 6(x - 1) = 0

Factor out x - 1

(6x - 6)(x - 1) = 0

Split

6x - 6 = 0 or x - 1 = 0

Solve for x in both instance

x = 1 or x = 1

Hence, the solution to the quadratic equation 6x² + 6 = 12x is x = 1
