Answer:
(x,7) or (x,10)
Step-by-step explanation:
It is given that two vertices of a right triangle have coordinates (3, 7) and (3, 10), we can see that the x-coordinate is same for both vertices, therefore it is a vertical line and thus base of the right angle triangle.
We need to find the height of this triangle which will be perpendicular to this line, so the value of y-coordinate of third point must be either 7 or 10.
Example
(8,7)
Answer:
1 and 2
Step-by-step explanation:
The sample is not a representation of the population, the population of students in colleges are high thus at least 10% of the population should be surveyed, this gives a better representation of the entire population.
The survey will also be biased as she stands outside the engineering building only and other students not belongings to this faculty might not be able to participate, thus the responses she will get will tend towards the favourable direction for the engineering students and will not reflects the entire students including non engineering students opinions on their college class schedule.
Answer: 9/10
Step-by-step explanation: The easiest way to divide fractions is to use KCF:
Keep the first fraction
Change the division sign to multiplication sign
Flip the second fraction
Let me explain. In this example, we have 3/4 ÷ 5/6. Well, if we applied our KCF rule here we would...
Keep 3/4
Change the division sign to multiplication
Flip 5/6
It should look like this:
3/4 × 6/5
Now we can just multiply the two fractions together:
3 x 6 = 18
4 x 5 = 20
18/20 = 9/10
Hope this was helpful! Let me know if you have any further questions. :)
Sandy. You take 3/10 and make it a decimal and that gives you .3 3/7 gives you .4 and 3/9 gives you .3.
Answer:
Here, x represents the weekly sale
As per the statement:
A salesperson earns $320 per week plus 8% of her weekly sales.
"8% of her weekly sales" means
then;
the expression which represents her earning =
"At least" means
then;
the sales necessary for the salesperson to earn at least $1000 in the one week
⇒
Subtract 320 from both sides we have;
Divide both sides by 0.08 we get:
Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e
