What is the arc length of arc cd in the circle below. The circle has a radius of 6ft and an angle measure of 30
Answers
9514 1404 393
Answer:
π ft ≈ 3.14 ft
Step-by-step explanation:
The angle is 1/12 of the number of degrees in a circle, so the arc length will be 1/12 of the circumference of the circle.
C = 2πr
1/12C = 2/12π(6 ft) = π ft ≈ 3.14 ft
The arc length is about 3.14 feet.

if (a+b)=3 and ab=2, find the value of a2+b2
Answers
Answer: so a^2 + b^2 = 5
Step-by-step explanation:
(a+b) = 3
ab = 2
so
(a+b)^2 = 3^2
a^2 + 2ab + b^2 = 9
or, a^2 + 2*2 + b^2 = 9
or, a^2 + 4 + b^2 = 9
or, a^2 +b^2 = 9-4 = 5

c. (4x+5)(x−5)
d. (3x+20)(x+5)
Answers
Answer:
The correct choice is option a. (2x+5)(2x−5)
Answer:
Option a. (2x+5)(2x-5)
Step-by-step explanation:
4x2 - 25
Furthermore, this is the difference of squares formula we will use to factor 4x^2-25:
a2 - b2 = (a + b) • (a − b)
As you can see, our problem does not look like the left side of the formula, so first we have to convert our problem to match the left side like so:
4x2 - 25 = (2x)2 - 52
Now that it matches, we can simply plug in 2x for a and 5 for b into the formula to get the factors of 4x^2-25:
(2x + 5) • (2x − 5)

A rectangular picture frame has length three inches longer than twice it’s width. The perimeter is 36 inches. Find the width of the frame.
a.) 5in
b.) 7in
c.) 10in
d.) 11in
Answers
Answer:
A. 5 in
Step-by-step explanation:
Let w represent the width of the frame.
If the length is 3 inches longer than twice the width, it can be represented by 2w + 3.
Use the perimeter formula, p = 2l + 2w. Plug in the perimeter and 2w + 3 as l, and solve for w:
p = 2l + 2w
36 = 2(2w + 3) + 2w
36 = 4w + 6 + 2w
36 = 6w + 6
30 = 6w
5 = w
So, the width of the frame is 5 inches.
The correct answer is A. 5 in

∴x−1009x=728,10091x=728,91x=728×100,x=756×100=800rupees
Step-by-step explanation:
MP of the fan is 2400.
To find the mp of the fan.
What is profit and loss?To buy goods from the shopkeepers in the market which they buy either directly from the manufacturers or through the wholesalers.
Given:
let’s calculate backwards :
2244 = 100% sale price + 10% VAT = 110%
1% = 2244 / 110 = 20.40
100% (actual sale price) = 20.40×100 = 2040
Now, because of the 15% discount, these 2040 are only 85% of the originally marked price.
2040 = 85%
1% = 2040 / 85 = 24.00
100% (the original marked price) = 24×100 = 2400
2244 is the final price. it includes the VAT based on the actual sale price. and that is then actually 15% lower than the originally marked price.
So, the MP of the fan is 2400.
