Answer:
a. 3/5 liters per hour
b .06 hours
Step-by-step explanation:
Change 40 minutes to a fraction of an hour
40 minutes/ 60 minutes = 2/3 hour
It takes 1 2/3 hours to fill the container
Changing to an improper fraction
(3*1+2)/3 = 5/3 hours
We want liters per hour
1 liter per 5/3 hours
1 ÷ 5/3
Copy dot flip
1 * 3/5 = 3/5 liters per hour
Change 100 ml to liters
We know 1000 ml = 1 lt
100 ml * 1 lt/1000 ml = .1 lt
So 100 ml = .1 lts
.1 lt * 3/5 lt per hour
Changing the fraction to a decimal
.1 lt * .6 lt per hour
.06 hours
The parallelogram<span>, rectangle, and </span>square<span> all have two pairs of parallel sides </span>
Answer:
y=2/5x+3/5
Step-by-step explanation:
Use the slope formula to get the slope:
m=4/10
m=2/5
The y intercept is 3/5
The equation is y=2/5x+3/5
Answer:
C. randomization
Step-by-step explanation:
We are told that the study randomly selects participants in the study to sleep in either a dark room or a room with light. This means that randomization is part of the study.
Ok so what you need to know about an octahedron is it's basically two square pyramids stacked on top of each other (one is upside down of course).
The formula for volume of a pyramid is Bh/3.
Base= 8*8=64
Height= 3 each
64*3/3= 64 mm^3 per pyramid.
64*2=128 mm^3 for the octahedron
Final answer: 128 mm^3
