A dog ran along a fence 10 times. The fence is 5 feet 3 inches long. How far did the dog travel? (12 inches = 1 foot)

Answers

52 feet and 2 inches

I converted the 5 ft and 3 inches to inches (63) I then multiplied that by 10 (630) and then divided it by 12. I believe this is correct tell me if I’m wrong!

The whole distance travelled by the dog is 630 inches.

We shall now approach the question in the following steps;

First, we shall convert the length of the fence to inches using the conversion factor as shown in the question.

12 inches = 1 foot

x inches = 5 feet

x = 12 inches × 5 feet /1 foot

x = 60 inches

The total length of the fence is 60 inches + 3 inches = 63 inches

The dog ran round it ten times hence the total distance travelled = 10 * 63 inches = 630 inches

Step-by-step explanation:

Select All the correct answers. Select all the statements that are true for the following systems of equations. System A 2x - 3y = 4 4xy18 System B 3x - 4y = 5 y = 5x + 3 System C 2x-3y и 4 12x-3y 54 System C simplifies to 2x-3y 4 and 4x y 18 by dividing the second equation by three. O Systems A and C have the same solution D Systems A and B have different solutions. Systems B and C have the same solution All three systems have different solutions.

Answers

Answer:

Step-by-step explanation:

Answer:

The true statements are:

the first statement: Systems A and C have the same solution

the fourth statement: System C simplifies to 2x - 3y = 4 and 4x - y = 18

the fifth statement: Systems A and B have different soltuoins.

Explanation:

1) The first statement: systems A and C have the same solutiotn: TRUE

The fourth statement proves that that the two systems are equivalent which means that both have the same solution.

2) The second statement: All three systems have different solutions: FALSE

The fourth statement proves that the systems A and C have same solution, so this second statement is false.

3) The third statement: Systems B and C have the same solution: FALSE

You can solve the two systems and will find the solutions are different

Solution of system B.

3x - 4y = 5

y = 5x + 3

replace y = 5x + 3 in the first equation => 3x - 4(5x + 3) = 5

=> 3x - 20x - 12 = 5

=> - 17x = 5 + 12

=> -17x = 17

=> x = - 17 / 17

=> x = - 1

y = 5x + 3 = 5(-1) + 3 = - 5 + 3 = - 2

=> solution x = -1 and y = -2

Solution of system C.

2x - 3y = 4

12x - 3y = 54

subtract

4) fourth statement: System C simplifies to 2x - 3y = 4 and 4x - y = 18 by dividing the second equation by three: TRUE

Look:

Second equation of system C = 12x - 3y = 54

Divide by 3:

12x - 3y 54

----------- = -----

3 3

Distributive property:

12x 3y

------ - ----- = 18

3 3

4x - y = 18, which is the same second equation of system A, so the system C simplifies to the same system A, which is 2x - 3y = 4 and 4x - y = 18.

5) The fifth statement: systems A and B have different solutions: TRUE

You can solve the two systems and will find the solutions are different

Solution of system A:

2x - 3y = 4

12x - 3y = 54 since it is equivalent to 4x - y = 18

-------------------

12x - 2x = 54 - 4 subtracting the first equation from the secon

10x = 50 adding like terms

x = 5 dividing by 10

From 2x - 3y = 4 => 3y = 2x - 4 = 2(5) - 4 = 10 - 4 = 6

=> y = 6 / 3 = 2

=> x = 5, y = 2

Solution of system B.

3x - 4y = 5

y = 5x + 3

replace y = 5x + 3 in the first equation => 3x - 4(5x + 3) = 5

=> 3x - 20x - 12 = 5

=> - 17x = 5 + 12

=> -17x = 17

=> x = - 17 / 17

=> x = - 1

Which is enough to prove that the two systems have different solutions.

Answer:

m(arc)RST = 154 deg

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary.

x + 77 + x + 103 = 180

2x + 180 = 180

2x = 0

x = 0

m<RST = x + 77 = 0 + 77 = 77

The measure of an inscribed angle is half the measure of its subtended arc.

m<RST = (1/2)m(arc)RST

77 = (1/2)m(arc)RST

154 = m(arc)RST

m(arc)RST = 154 deg

The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)t . What is the rate of decrease of original oxygen?

Answers

Answer:

24%

Step-by-step explanation:

The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)^t . What is the rate of decrease of original oxygen?

The formula for Exponential Decrease is given as:

y = a(1 - r)^t

Where

y = Amount after time t

a = Original amount

r = Rate of decrease

t = Time

Comparing both Equations

y = 0.32(0.76)^t = y = a(1 - r)^t

We know that

0.76 = 1 - r

Solving for r

Collect like terms

r = 1 - 0.76

r = 0.24

Converting to Percentage

= 0.24 × 100

= 24%

Therefore, the rate of decrease of original oxygen is 24%
