What is the perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters?

Answers

Answer 1

Answer: The answer is 23cm just add the sides

Answer 2

Answer:

The perimeter is the sum of all of the lengths of the sides. To find the perimeter, add together the length of each side.

For this triangle, our side lengths are 7, 7, and 9.

7 + 7 = 14

14 + 9 = 23

The perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters is 23 centimeters.

Hope this helps!! :)

twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousandths. what is the value of d?

Answers

12 3/10 (12 3/10) more than (+) 5 13/1000 of a number d (5 13/1000d) is equal to (=) 15 and 302/1000 so

we want the bottom numbers the same so

12 and 3/10=12 and 300/1000
5 and 13/1000 is the same
302/1000 is the same so

12 300/1000+5 13/1000d=15 302/1000
subtract 12 300/1000 from both sides
5 13/1000d=3 2/1000
5 13/1000d=5013/1000d
3 2/1000=3002/1000
5013/1000(d)=3002/1000
multiply both sides by 1000/5013 (to make it a one exg 1/2 times 2/1=2/2=1)

d=3002/5013 times 1000/1000=3002/5013≈0.59843

The radius r of a circle can be written as a function of the area A with the following equation: What is the domain of this function? Explain why it makes sense in this context.

Answers

Answer:

Hence, the domain of the function is:

[0,∞)

Step-by-step explanation:

We know that area of circle is given by the function:

$A=\pi r^2$

The radius r of a circle can be written as a function of the area A with the following equation:

Now we can represent r in terms of A as:

$r^2=(A)/(\pi)\n\nr=\sqrt{(A)/(\pi)}$

Now as we know that for the square root term to exist:

$\sqrt{(A)/(\pi)}\geq0$

i.e. $A\geq0$

A=0 represents a point circle since it's area is zero.

Hence, the domain of the function is:

[0,∞)

[0,infinity) because you can not take the radius of a negative mumber.

Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M. How many degrees did the minute hand turn?

Answers

Answer:

The minute hand covered 120 degrees

Step-by-step explanation:

Minute hand completes 1 round in 60 minutes

1 round = $360^(\circ)$

So, The minute hand covered degrees in 60 minutes = $360^(\circ)$

The minute hand covered degrees in 1 minute $= (360^(\circ))/(60^(\circ))$

Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M.

So, He watched it for 20 minutes

So,The minute hand covered degrees in 20 minutes = $(360^(\circ))/(60^(\circ)) * 20 =120^(\circ)$

Hence The minute hand covered 120 degrees

What is 6:12 in simplest form

Answers

6/12 in simplest form is 1/2

In simplest form, the ratio 6:12 is equivalent to 1:2.

To simplify the ratio 6:12, we need to find the greatest common divisor (GCD) of the two numbers and then divide both numbers by the GCD.

Step 1: Find the GCD of 6 and 12.

The factors of 6 are 1, 2, 3, and 6.

The factors of 12 are 1, 2, 3, 4, 6, and 12.

The greatest common divisor (GCD) of 6 and 12 is 6.

Step 2: Divide both numbers in the ratio by the GCD (6).

6 ÷ 6 = 1

12 ÷ 6 = 2

Step 3: Write the simplified ratio as 1:2.

In simplest form, the ratio 6:12 is equivalent to 1:2. This means that both numbers in the ratio have been divided by their greatest common divisor to give the simplest representation. The simplified ratio 1:2 indicates that there is one unit of the first quantity for every two units of the second quantity.
