1. We've got everything to write the expression. Here it is: √48 - √27.
We can simplify it into:
1) (√16 * 3) - (√9 * 3);
2) 4√3 - 3√3;
3) √3.
2. Here we also have everything to write the expression which represents the total distance covered by this over the two day period. The expression looks like this: √750) + √1080.We were asked to simplify that:
1) (√25 * 30) + (√36 * 30);2) 5√30 + 6√30;3) 11√30.
3. The same situation. We have all we need to write an expression to represent the difference between the two distances of each route. Here is the expression: √605 - √500.
We need to simplify it:1) (√121 * 5) - (√100 * 5);2) 11√5 - 10√5;
3) √5.
4. We've got all values to write the expression which represents the total length across the diagonals of both circuit boards. It looks like this: √24 + √54.
Then let's simplify it step by step1) (√4 * 6) + (√9 * 6);2) (2√6) + (3√6);3) 5√6.
At the beginning you have 10 balls, 5 of which are red. So, the chance of picking a red ball with the first pick is
When it comes to the second pick, you have 9 balls (because you didn't replace the first red ball), 3 of which are blue. So, you pick a blue ball with the second pick with probability
The two events will occur one after the other with the product of the probabilities:
9/-12 is an obvious answer to eliminate as the numerator is not negative and the denominator is not positive. -15/20 simplified is -3/4, so you have to find a similar fraction. This means that D and A are eliminate and leaves you with C as the answer.
Answer:
-131
Step-by-step explanation:
(0 − 3) − 8(12 + 4) =
= -3 - 8(16)
= -3 - 128
= -131
Answer:
15 and 20
Step-by-step explanation:
When dividing 88 by 5 we wil have;
88/5
= 17 3/5
= 17 + 0.6
= 17.6
So we are to find the two numbers that 17.6 falls in between
From the given option 17.6 falls between 15 and 20. Hence the required numbers are 15 and 20
