Answer:-2
Step-by-step explanation:
Joel read the greatest number of pages in a day.
Armando read (46×.15) 6.9 pages.
Billy read (72×.11) 7.92 pages.
Robert read (68×.12) 8.16 pages.
Joel read (69×.14) 9.66 pages.
1) y= -4x+c
2) y= 3x+c replace x and y to find c , 5=3(2)+c
C= -1
Y=3x-1
3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c
C= -2/3 and so y= -1/3x-2/3
4) DO THE SAME STEP AS NUMBER 3 and enjoy!
TheThe best approximation for the perimeter of polygon ABCDE is: C. 24.3 units.
<h3>Perimeter of polygon</h3>
Coordinate:
A=(-2,3)
B=(0,6)
C=(5,4)
D=(4,-1)
E=(-1,-2)
Distance AB=√(0+2)²+(6-3)²
Distance AB=√4+9
Distance AB=√13
Distance BC=√(5-0)²+(4-6)²
Distance BC=√25+4
Distance BC=√29
Distance CD=√(4-5)²+(-1-4)²
Distance CD=√1+25
Distance CD=√26
Distance DE=√(-1-4)²+(-2+1)²
Distance DE=√25+1
Distance DE=√26
Distance EA=√(-2+1)²+(3+2)²
Distance EA=√1+25
Distance EA=√26
Perimeter of pathogen ABCDE
=AB+BC+CD+DE+EA
=√13+√29+√26+√26+√26
=√13+√29+3√26
=24.2877 units
= 24.3 units (Approximately)
Therefore the correct option is C.

Answer:
<em>Option C. Luigi runs 150 laps in 10 hours
. </em>
Step-by-step explanation:
<u>Unit Rate</u>
We need to match for an option having a unit rate of 15 laps per hour.
To find the required rate, we divide the number of laps by the number of hours.
A. Luigi runs 44 laps in 4 hour
. This gives a unit ratio of 44/4 = 11 laps/hour. This is not the correct option
B. Luigi runs 2 laps in 30 hours. This gives a unit ratio of 2/30 =0.07 laps/hour. This is not the correct option
C. Luigi runs 150 laps in 10 hours
. This gives a unit ratio of 150/10 = 15 laps/hour. This is the correct option
D. Luigi runs 60 laps in 5 hours. This gives a unit ratio of 60/5 = 12 laps/hour. This is not the correct option
Option C. Luigi runs 150 laps in 10 hours
.
