That bracket symbol, with an r in it, means "the absolute value of r".
So r's absolute value is -2 meaning r is two units from zero
r= 2
Answer: The Red Car
Step-by-step explanation: if you divide the speed the blue car is going with the distance the blue car will arrive there in 6 hours while the red car will arrive in 5
Answer:
3/22
Step-by-step explanation:
-1/4 . (-6/11)
- You have to multiply the signs: As both are negative, the result will be positive.
- You have to multiply the numbers in the top part (numerators) and the numbers in the bottom part (denominators)
1 . 6 / 4 . 11 = 6/44
- Finally, you must simplify the answer by dividing both numbers among the same divisor, in this case the number is 2
6÷2 / 44÷2 = 3/22
<span>Let,
diameter = segment AB through center P.
Set the compass to the radius PB, at B and draw two little arcs that intersect the circumference of the circle at C and D.
Then Triangle ACD will be an equilateral triangle inscribed in the given circle.
Hence,
The right option is :
</span><span>B. Open his compass to a width equivalent to the radius of the circle.</span>
Answers:
- AE = 26
- AN = 58
- CT = 22.5
- Perimeter of triangle AEN = 127
=========================================================
Work Shown:
Because points C, P, and T are midpoints of the sides of triangle AEN, this means the segments CP, PT, and CT are midsegments of triangle AEN.
The segment PT = 13 is a midsegment of the larger triangle, and it is parallel to the side AE. Recall the midsegment is half as long as its parallel side.
This means,
PT = (1/2)*AE
2*PT = AE
AE = 2*PT
AE = 2*13
AE = 26
---------------
We'll use the same idea to find AN
CP = (1/2)*AN
2*CP = AN
AN = 2*CP
AN = 2*29
AN = 58
---------------
And we can also say,
CT = (1/2)*EN
CT = (1/2)*43
CT = 22.5
----------------
Add up the sides of triangle AEN to find its perimeter
Perimeter of triangle AEN = (AE)+(EN)+(AN)
Perimeter of triangle AEN = (26)+(43)+(58)
Perimeter of triangle AEN = 127
