If you simplify, the first step is to Multiple -1 by the -2 and - 2 In the parenthesis.
Which will give you -3 + 2 + 2
Then you add them together. Then solve 4 -3 = 1

17.5% of 120 can be worked out using the following method find 10% of 120=12 then 5% of 120=6 then 2.5% of 120=3. Adding 17.5% o

Answer:

17.5% of 360 = 63

Step-by-step explanation:

We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find 10% of 360 , we get,

$\frac{10}{100} \times 360=36$

STEP 2 : find 5% of 360, we get,

$\frac{5}{100} \times 360=18$

STEP 3: find 2.5% of 360 , we get,

$\frac{2.5}{100} \times 360=9$

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360

⇒ 17.5% of 360 = 36 + 18 + 9

⇒ 17.5% of 360 = 63

0 less than or equal to theta less than 2pi

Arisa [49]

Answer:

theta = 4.5642792103077898247

Step-by-step explanation:

0 <= theta < 2Pi sin(theta) = 1/2

2Pi sin(theta) = 1/2

Pi sin(theta) = 1/4

sin(theta) = 1/(4Pi)

sin(theta) = .0795774715459

theta = arcsin(.0795774715459) = 4.5642792103077898247

=Rs. 8.3 per pair

Required

The percent discount

Step two:

%percent discount= 12-8.3/12*100
