Answer:
165
Step-by-step explanation:
55* 3 = = 165
First you would multiply left to right. So 50*3 is 150 and then 150*3 is 450. 450*20 is 9000. 9000 is your answer.
The answer that I got was 15.
You start by setting the angles equal to each other, because they are verticle angles. You then distribute 11 to get 11y + 110 = 4y - 5.
You then just have to simplify, which I got -105 = -7y.
You can multiply each side by -1 to make them positive and divide 7 by 105 to get 15.
Answer: a. 9
b. 1/3
c. 1/4
d. 1/12
Step-by-step explanation:
White balls = 6
Orange balls = 3
a. Total number of balls = 6 + 3
= 9
Total balls in bag = 9
b) Probability that the first ball is orange
= No. of orange balls / Total no. of balls
= 3 / 9
= 1 / 3
c) To give the required probability
If one ball being the orange ball has been taken out then the remainder are,
Total balls = 8
If Orange balls = 2
Therefore the probability that the 2nd ball is also orange, given that the 1st ball was orange will be denoted by,
= P(2nd ball|1st orange)
= 2 / 8
= 1 / 4
d) To give the probability that both the 1st and the 2nd balls are orange you multiple their probabilities.
Probability = 1 / 3 * 1 / 4
= 1 / 12
Step-by-step explanation:
x+2<−5
Step 1: Subtract 2 from both sides.
x+2−2<−5−2
x<−7
Answer:
x<−7
