The circumference of a circle is 8.88cm. Find the length of the diameter. Give your answer rounded to 2 DP.

Answers

Answer:

2.82

Step-by-step explanation:

The formula for the circumference of a circle is given as:

π × D

Where D represents the Diameter of the circle.

From the question:

The circumference of a circle is 8.88cm.

The Length of the Diameter is calculated as:

8.88cm = π × D

D = 8.88 cm/π

D = 2.8265917893 cm

Approximately to 2 decimal places = 2.83cm

Therefore, the length of the diameter = 2.83 cm

On a triangle, one side measures 4x2−2x and another side measures 2x2 −5x+1. If the perimeter of the triangle is 9x2 + x+6, what is the measure of the third side of the triangle? (Your answer will be an expression)

Answers

Answer:

3x² + 8x + 5

Step-by-step explanation:

Subtract the sum of the 2 given sides from the perimeter, that is

9x² + x + 6 - (4x² - 2x + 2x² - 5x + 1)

= 9x² + x + 6 - (6x² - 7x + 1 ) ← distribute parenthesis by - 1

= 9x² + x + 6 - 6x² + 7x - 1 ← collect like terms

= 9x² + 8x + 5

Please help me
And I need the correct answer

Answers

The answer is A, 9 hours

Distance = rate of speed • time
765 = 85 • t
765/85 = t
9 = t
As you probably know, you can switch and mismatch the different terms in equations.


So since the equation for distance is d = r (or speed (s)) multiplied by time.


We can move speed to the other side of the equation by dividing it out.


I’ll be putting rate as speed instead btw.

d/s = t

Now we got the equation for time.



Just substitute and we get 765/85 = time, which is 9.

Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?

Answers

Answer:

51 meters

Step-by-step explanation:

Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?

We are to find the meters of fencing for the diagonal.

We solve the question using Pythagoras Theorem

= c² = a² + b²

Where

c = Diagonal

a = Width

b =Length

Diagonal² = Width² + Length ²

Hence:

Diagonal ² = 45² + 24²

Diagonal = √45² + 24²

Diagonal = √(2601)

Diagonal = 51 m

Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters

Step-by-step explanation:

From the above question,

We have the Algebraic expression

(5x - 4)° + 94° = 180°

5x - 4° + 94° = 180°

5x + 90° = 180°

5x = 180° - 90°

5x = 90°

x = 90°/5

x = 18
