triangle ABC below has a right angle C and a height CD. (A height in a triangle connects it vertex and the opposite side, and is perpendicular to that side.) If AC is 3 untis long and BC is 4 units long, what is the length of CD?
Answers
9514 1404 393
Answer:
2.4
Step-by-step explanation:
We can see that this is a 3-4-5 right triangle, so side AB is 5 units long.
The area of the triangle is ...
A = 1/2bh = 1/2(3 units)(4 units) = 6 units
This is true also when side AB is the base and CD is the height.
A = 1/2(AB)(CD)
6 = 1/2(5 units)(CD) . . . . . substitute given information
6/2.5 = CD = 2.4 . . . . . . . divide by the coefficient of CD
The length of side CD is 2.4 units.
__
In the attached, the height to vertex C is given on the bottom line.

A student had 10 marks in mathematics. But he remembers only 7 of them:
1,1,2,2,3,4,5. The mode of the marks is 3 and the mean is 2.9. What are the
missing marks? Once you manage to find these marks, create a frequency
table for the students' scores and visualize the results with a bar chart.
Answers
Answer:
The missing marks are 3, 3, and 5.
Step-by-step explanation:
Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.

The Rational Root Theorem says that any rational root has
1. a numerator that is a factor of the constant term
2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)
Numerator: [tex]\pm 1[/tex]
Denominator: [tex]\pm 2[/tex]
That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]
Try them both by plugging them into the polynomial.

Omar, Hala and Lujain got paid a total of $240 for cleaning neighborhood cars. They split the money in the ratio of 5: 9: 10. How much money did Omar earn?
Answers
Answer:
Total amount Omar earn = $120
Step-by-step explanation:
Given:
Total amount Omar, Hala and Lujain got paid = $240
Ratio of money Omar, Hala and Lujain got paid = 5:9:10
Find:
Total amount Omar earn
Computation:
Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]
Total amount Omar earn = [240][5 / (5+9+10)]
Total amount Omar earn = [240][5 / (24)]
Total amount Omar earn = [24][5]
Total amount Omar earn = $120
