Radda [10]

Use the Pythagorean theorem

let = length of ram = l

l² = 4² 18²
l² = 16 + 324
l² = 340
l = 18.4390889146
l = 18.4 ft.

Answer:

c)30%

Step-by-step explanation:

Step one:

given data

The shopkeeper said each pair of earrings cost Rs. 12

if he offered 12 pairs for Rs. 100.

let us find the cost per pair

= 100/12

=Rs. 8.3 per pair

Required

The percent discount

Step two:

%percent discount= 12-8.3/12*100

%percent discount= 3.66/12*100

%percent discount= 0.305*100

%percent discount= 30.5%

100 people who were surveyed and asked the question: ``Is fuchsia kinda pink, or purply?'' Of them, 60 believe that fuchsia is `

Kay [80]

Answer:

Step-by-step explanation:

Let the event of people who believe that fuchsia is pink = A

Let the event of people who believe that fuchsia is purply = B

Since 100 people were surveyed, the Universal Set =100
60 believe that fuchsia is ``kinda pink'', n(A)=60
27 believe it is both ``kinda pink,'' and also ``purply.'': $n(A \cap B) =27$
17 think that fuchsia is neither ``kinda pink'' nor ``purply. $n(A \cup B)'=17$

We want to determine the number of those who believe that fuchsia is ``purply'', n(B).

In set theory, we have:

$U=n(A)+n(B)-n(A\cap B)+n(A \cup B)'\\100=60+n(B)-27+17\\100=50+n(B)\\n(B)=100-50\\n(B)=50$

Therefore, the number of those who believe that fuchsia is ``purply'' is 50.
