Answer:444
Step-by-step explanation:
1/2 time base times height times 4
And then base times height times 4
add them together
1. x = 2
2. x = 9
3. a = 3
4. x = 13
5. c = 3
6. s = 3
7. x = 7
8. c = 0
9. b = 1
10. c = 4
11. x = 4
12. x = 8
13. x = 12
14. y = 10
15. x = 11
16. x = 10
17. x = 6
18. x = 11
The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66
<u>Step-by-step explanation:</u>
<u>From the table shown:</u>
- The students in the eighth grade = 13
- The eighth grade students using internet = 8
P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)
⇒ 8/13
⇒ 0.66
Given:
The ratio of the measures of the sides of a triangle is 3:4:5.
Its perimeter is 48 inches.
To find:
The scale factor as a decimal, and the measure of each side of the triangle.
Solution:
Let x be the scale factor. Then the measures of sides of the triangle are 3x, 4x and 5x.
The perimeter of the triangle is 48 inches. It means the sum of all sides of the triangle is 48 inches.
Divide both sides by 12.
Now, the measures of sides are:
Similarly,
And,
Therefore, the scale factor is 4 and the measures of sides are 12, 16 and 20.
A = P(1 + r)^n
where A is the amount after n years, P = principal( initial amount), r = annual rate as a decimal fraction and n = number of years
If interest is accumulated say monthly then it would be
A = P(1 + r/12)^12n
For quarterly replace the 12 by 4
