Which of the following sets of numbers could be the lengths of the sides of a triangle?

kicyunya [14]

Answer is C. 8, 3, 6

To answer this, you must know the Triangle Inequality Theorem.

The two shortest sides when added together, must be greater than the longest side.

A. 2 + 4= 6 which can't work since it equals the longest side of 6

B. 4 +2=6 The sum would be less than 8, which doesn't work

C. 6 +3 = 9 the sum is greater than 8, which makes it a triangle

D. 3 +8 = 11 11 is less than 12

You are rolling two dice at the same time. What is the probability of rolling a sum of 5 or 9?

baherus [9]

You can get a 5 by rolling :
1 and 4
2 and 3
3 and 2
4 and 1

You can get a 9 by rolling :
3 and 6
4 and 5
5 and 4
6 and 3

There are 36 possible outcomes, hence your probability is $\frac{4\cdot2}{36}=\boxed{\frac29}$

The length of a rectaangle 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle ca

Monica [59]

Answer:

Step-by-step explanation:

We are told that the perimeter is 48 = 2L + 2W. This reduces to

24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:

a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm

b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm

c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm

On a lunch counter, there are 3 oranges, 5 apples, and 2 bananas. If 3 pieces of fruit are selected, find the probability that 1

muminat

Answer:

$Probability = \frac{1}{24}$

Step-by-step explanation:

Given

$Oranges = 3$

$Apples = 5$

$Banana = 2$

$Total = 10$

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

$Probability = P(Orange) * P(Apple) * P(Banana)$

$Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}$

<em>The difference in the numerator is as a result of picking the fruit without replacement</em>

$Probability = \frac{30}{720}$

$Probability = \frac{1}{24}$
