The perimeter of a rectangle is 46 cm,<br> The length is 13 cm. What is the width?
Firlakuza [10]

Answer:

10 cm

Step-by-step explanation:

we know that the perimeter of a rectangle= 2(l+w)

given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,

2(13+w)=46

= 26+2w=46 (opening the brackets)

= 2w= 46-26

= 2w=20

= w=20/2

w= 10 cm

Answer:

0.14

Step-by-step explanation:

From the question given above, the following data were obtained:

Grade A = 5

Grade B = 10

Grade C = 15

Grade D = 3

Grade F = 2

Sample space (S) = 35

Probability of getting grade A, P(A) =?

The probability that a student obtained a grade of A can be obtained as follow:

Probability of getting grade A, P(A) =

Event of A (nA) / Sample space, (nS)

P(A) = nA/nS

P(A) = 5/35

P(A) = 0.14

Thus, probability that a student obtained a grade of A is 0.14
