There will be 38 grams remaining.
The equation would be of the form
y = a(1+r)ˣ, where a is the initial value, r is the rate as a decimal number, and x is the amount of time. Using our values from the problem, we have:
y = 670(1-0.273)^9 = 670(0.727)^9 = 38
Answer:
22 cm
Step-by-step explanation:
Start off by multiplying the number of pages by the thickness.
200*0.008=1.6
Add the thickness of the front and back cover.
1.6+0.6=2.2
Multiply by 10.
2.2*10=22 cm
Answer:
.5 hour, or 30 minutes
Step-by-step explanation:
280 km / 80 kmh = 3.5 hr before limiter
280 km / (80-10) kmh = 4 hr after
so .5 hour from 3.5 to 4 hours. or 30 minutes
This is provided he matains this speed at all times.
Answer:
B and D
Step-by-step explanation:
A 20 degree intercepted arc will correspond with two angles: the inscribed angle and the central angle.
The central angle always has the same degree measure as the intercepted arc, so we want a central angle with degree 20. So, that's B.
The inscribed angle is the angle whose vertex is on the circle, not the center. This angle always has half the measure of the intercepted arc, so we want an angle with degree 20/2 = 10. So, that's D.
Thus, the answers are B and D.
Hope this helps!
Answer:
Step-by-step explanation:
We can treat this as a units conversion problem. Each multiplier is a fraction that has the same value in the numerator as the denominator, but expresses that value with different units. We choose to cancel units we don't want, and replace them with units we do want. Ultimately, we're evaluating the expression ...
time = quantity/rate
(4 mi²) × (640 ac/mi²) × (5 min)/(2.5 ac) × (1 h)/(60 min)
= (4·640·5)/(2.5·60) h = 85 1/3 h
It will take about 85 hours to plant the farm.
__
At 8 hours per day, that is (85 1/3)/(8) = 10 2/3 days.
It will take about 11 days to plant the farm.
