<u>Answer:</u>

P = 53.6 square cm

<u>Step-by-step explanation:</u>

We know that the measure of an arc of a sector is given by: P=\theta r+2r

Where \theta  is the angle of the arc of the sector (radian) while r is the radius of the circle.

Here, \theta = 90°=\frac{\pi }{2}.

Substituing the given values to get:

P=\frac{\pi}{2}(15)+2\times 15

P = 53.6 square cm

A bucket is sold at a profit equal to one - fifth of its cost price find profit percentage ​
Tresset [83]

Answer:

20% profit margin!

Step-by-step explanation:

Let suppose If the cost of a bucket is $100.

As the bucket is sold to 1/5 of the bucket cost.

i.e. 1/5 × 100 = $20

We know that 20% of 100 is 20.

i.e. 20/100 × 100 = 20

It mathematically means if the cost of the bucket was 100, and he sold at a profit equal to one - fifth of its cost price. It indicates that he earned a $20 profit. In other words, the person got a 20% profit percentage.

Note: I tried to take sample costs like $100 to make you understand as simple as I can.

Thus, if a  bucket is sold at a profit equal to one - fifth of its cost price, the profit margin will always 20%, because if there are 5 parts of an object, 1 part makes the 20%.

I hope you get my point.

A ladder is leaning up against a 17 foot Wall at an angle of elevation of 37°. How far is the foot of the latter from the wall?
inn [45]
This is the concept of trigonometry, the distance from the foot of the ladder will be given by:
tan theta=[opposite]/[adjacent]
opposite=17 ft
adjacent=x ft
theta=37°
thus
tan 37=17/x
x=17/tan 37
x=22.56 ft
=22.6 ft (to the nearest 10th of a foot)
