Answer:
Amount of weight Kari lost in pound = 6.34 pound (Approx.)
Step-by-step explanation:
Given;
Amount of weight Kari lost in kilogram = 2.88 kilograms
Given scale;
1 kilogram = 2.2 pound
Find:
Amount of weight Kari lost in pound
Computation;
Amount of weight Kari lost in pound = Amount of weight Kari lost in kilogram x 2.2 pound
Amount of weight Kari lost in pound = 2.88 x 2.2 pound
Amount of weight Kari lost in pound = 6.336
Amount of weight Kari lost in pound = 6.34 pound (Approx.)
Jason = 142 cm = 1.42 m
Amy = 137 cm = 1.37 m
Joseph = 1397 mm = 1.397 m
From shortest to tallest
I) Amy, Joseph, Jason
This is the concept of simultaneous equations, the question requires us to solve the system of equations given by:
2x+4y=38
10x+3y=105
from the top equation;
2x=38-4y
dividing through by 2 we get:
x=19-2y......(*)
substituting (*) in the second equation we get:
10x+3y=105
10(19-2y)+3y=105
190-20y+3y=105
collecting like terms we get:
-20y+3y=105-190
-17y=-85
dividing both sides by -17 we get:
(-17y)/(-17)=(-85)/(-17)
y=5
thus
x=19-2y
x=19-2*5
x=19-10
x=9
thus
x=9 and y=5
Answer:
A odd index can go to " - infinity "
Step-by-step explanation:
Distance is speed or velocity multiplied by time: d = v * t
We know the speed of the car and the time it travelled, so input the two into the equation above and solve for the distance travelled.
d = v * t
d = 64 m/h * (5 hours and 15 minutes) = 64 m/h * (5.25 hours)
d = (64 * 5.25) miles
d = 336 miles
