Answer:
of what? i know how to do these but tell me the equation
Step-by-step explanation:
you asked a very not telling question. need more info to give an answer
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
180° because it is half of a full circle(360°)
Answer:
4.4
Step-by-step explanation:
Answer:
B.) Probability of 1/6
Step-by-step explanation:
To determine which of the options is least likely to occur, first convert all of them to the same form (fractions, decimals, percentages, etc.). Since 2 are already in fraction form, let's convert the other one to fraction form as well.
0.4 = 4/10
4/10 = 2/5
Now, the probabilities are 2/5, 1/6, and 2/3. Since 1/6 is the smallest number out of the three, that option is correct; a probability of 2/3 the least likely to occur.
