Suppose you roll a six sided number cube one time. What is the probability of rolling a 3 or an even number

1 answer:

8 0

There are 3 even numbers: 2,4,6. If you add 3 there is 4. There is 6 possible outcomes 1,2,3,4,5,6. So the probability is 4/6, 2/3, 66.666....% or 0.6666666....

The length of a rectangle is "a" inches and the width is 3 inches more than its length. find the perimeter and the area

Alex73 [517]

Answer:

Step-by-step explanation:

Givens

Length = a

Width = a + 3

Formulas

P = 2L + 2w

Area = L * w

Solution

Perimeter

P = 2L + 2w

P = 2*a + 2(a + 3) Remove the Brackets

p = 2a + 2a + 6 Combine

P = 4a + 6

Area

Area = L * w

Area = a (a + 3)

Area = a^2 + 3a

maks197457 [2]

Answer:

4 hectares

Step-by-step explanation:

The scale factor is:

k = 1/400

Applied to the area we consider k² as the area is the product of two dimensions.

Find the actual area:

0.25 m² : (1/400)² =
0.25 m² * 160000 =
40000 m² =
40000 * 1/10000 hectares =
