The function V(h(r)) is limited to r values that are greater than 0. V(h(r)) = 3.5πr^3. The volume is dependent on the cylinder's radius. Step-by-step explanation: Edgenuity.
Density can be defined as:
Where:
m is mass
V stands for volume
To isolate the mass, we derive:
Volume can be expressed as:
We then use the following conversion:
After applying the conversion, we arrive at:
Additionally, we have these conversions:
When we apply these conversions for density, we conclude:
Finally, the mass of the water required is:
Answer:
A total of 1190 kilograms of water is needed to fill the waterbed.
Answer:
5%
Step-by-step explanation:
With four individuals, each receives 25% of the halwa. Yet, when a fifth individual joins, each share drops to 20%. Consequently, the original four individuals experience a 5% reduction in their servings due to the new arrival.
Answer:
qt's length = 16
Step-by-step explanation:
The problem states that qrs is a right triangle,
where qr = 20
sr =?
qs = 25
qt =?
1)
Calculate sr
hypotenuse² = base² + height²
sq² = sr² + rq²
25² - 20² = sr²
sr = √(25² - 20²)
sr = 15
2)
When altitude rt is dropped to hypotenuse qs, it creates
two right triangles: rtq and rts.
Δrtq
height = rt
base= tq = 25 - x
hypotenuse = qt = 20
Δrts
height = rt
base= ts = x
hypotenuse = sr = 15
Both triangles share the same height, which is rt
Using the Pythagorean theorem:
Δ rtq Δ rts
hypotenuse² - base² = height²
20² - (25 - x)² = 15² - x²
400 - (625 + x² - 50x) = 225 - x²
400 - 625 - x² + 50x = 225 - x²
-225 - x² + 50x - 225 + x² = 0
-450 + 50 x = 0
50x = 450
x = 450/50
x = 9
Base of Δ rtq = tq = 25 - x
tq = 25 - 9
tq = 16
