The diameter of a circle is 14 ft.
What is the area of the circle in terms of π?

Answers

Answer 1

Answer:

49π ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where r is the radius of the circle

To find the radius, divide the diameter by 2:

14 ft ÷ 2 = 7 ft

Plug the radius 7 ft into the equation

[tex]A=\pi (7)^2\\A=49\pi[/tex]

Therefore, the area of the circle in terms of pi is 49π ft².

I hope this helps!

Answer 2

Answer:

49π

Step-by-step explanation:

Diameter=14

Radius=14/2=7

Area=πr squared

Area=7 squared π

Area=49π

2 CDs and 9 DVDs cost £69. 2 CDs and 6 DVDs cost £48. i. Form a pair of simultaneous equations to represent these two sentences ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.

Answers

Answer:

Cost of 1 CD = x = £3

Cost of 1 DVD = y = £7

Step-by-step explanation:

Let us represent:

Cost of 1 CD = x

Cost of 1 DVD = y

i. Form a pair of simultaneous equations to represent these two sentences

2 CDs and 9 DVDs cost £69.

2x + 9y = 69.... Equation 1

2 CDs and 6 DVDs cost £48.

2x + 6y = 48..... Equation 2

ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.

Combining both equations together:

2x + 9y = 69.... Equation 1

2x + 6y = 48..... Equation 2

We substract Equation 2 from Equation 1

3y = 21

y = £7

Solving for x using Equation 1

2x + 9y = 69.... Equation 1

2x + 9 × 7 = 69

2x + 63 = 69

Collect like terms

2x = 69 - 63

2x = 6

x = 6/2

x = £3

Therefore,

Cost of 1 CD = x = £3

Cost of 1 DVD = y = £7

Wendy randomly chooses a positive integer less than or equal to 2020. The probability that the digits in Wendy's number add up to 10 is m/n, where m and n are relatively prime positive integers. Find m+n.

Answers

Answer:

107

Step-by-step explanation:

Probability = numbers that add up to 10 / total of numbers

There are 120 positive integers between 1 - 2020 that add up to 10.

120 / 2020

convert to its simplest form by dividing by 20

Answers

Applying the Pythagorean theorem, we have ΔPQR ≅ ΔABC. then we would have: ∠ACB = ∠PRQ = 90°

What is the Pythagroean Theorem?

The pythagorean theorem states that the square of the longest side (hypotenuse) of a right triangle is always equal to the sum of the squares of the other two sides (legs) of the right triangle.

Since we know that ΔPQR is a right triangle, then:

x² + y² = PQ²

We are also given that x² + y² = z², so by substitution, we have:

z² = PQ², which makes both triangles have corresponding congruent sides. Therefore, ΔPQR ≅ ΔABC.

Using the corresponding parts of the congruent triangles, we can conclude that: ∠ACB = ∠PRQ = 90°.
