Answer: V≈1642 cm³.
Step-by-step explanation:
D=20 cm d=12 cm h=8 cm V=?
[tex]R=\frac{D}{2}=\frac{20}{2} =10 \ (cm).\\ r=\frac{d}{2}=\frac{12}{2}=6 \ (cm).\\ \boxed {V=\frac{1}{3} *\pi *h*(R^2+R*r+r^2)} \ \ \ \ \ \Rightarrow\\V=\frac{1}{3}*\pi *8*(10^2+10*6+6^2)\\V=\frac{1}{3}*\pi *8*(100+60+36)\\ V=\frac{8}{3} *\pi *196\\V=\frac{8*196*\pi }{3} \\V\approx1642\ cm^3.[/tex]
The average height of American women (in 2016) is 5 ft. 4 inches (64 inches) with a standard deviation of 3 inches. What is the probability that the average height of a random group of nine American women would be less than five feet three inches
Probability of average height of women is 0.1379
First check to see if the Central Limit Theorem applies. Since n > 30, it does. Next we need to calculate the standard error. To do that we divide the population standard deviation by the square-root of n, which gives us a standard error of 0.646. Next, we calculate a z-score using our z-score formula:
Z=(X−μ)/S.E.
S.E = σn/√n
S.E =3/√ 9
S.E=1
Plugging in gives us:
(64−63)/1 = 1
Finally, we look up our z-score in our z-score table to get a p-value.
The table gives us a p-value of,
P(z<1.0)=1−P(z>1.0)
P(z<1.0)=1−0.8621
P(z<1.0)=0.1379
So, Probability of average height of women is 0.1379

Solve x please explain
Answer:
x = 4
Step-by-step explanation:
co interior angles add up to 180.
this means that: 48 + 34x - 4 = 180
thus 48 + 34x = 184
therefore, 34x = 136
so, x = 4.
The two angles labeled in the given diagram are interior angles on the same side of the transversal. They can also be called interior supplementary angles.
These angles have a sum of 180 degrees.

A rectangle has a length of 6x-5y+1. If the perimeter of the rectangle is 16x-4y-4, determine an expression for its width
Answer:
2x +3y -3
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of all its sides.
Perimeter of a rectangle= 2 length +2 width
16x -4y -4= 2(6x -5y +1) +2(width)
Expand:
16x -4y -4= 12x -10y +2 +2(width)
2(width)
= 16x -4y -4 -(12x -10y +2)
= 16x -4y -4 -12x +10y -2
= 4x +6y -6
2(width)= 2(2x +3y -3)
Divide both sides by 2:
width= 2x +3y -3
If three farmers share some bags of fertilizers in the ratio 3:4:5.if the smallest share is 18 bags.what is the largest share
Answer:
30
Step-by-step explanation:
Sum of the ratios = 3 + 4 + 5 = 12
Smallest share = 18 bags
Ratio of the smallest share = 3
Let the largest share = x
From the question
18 ------------ 3
x --------------5
Cross multiply
3x = 18 × 5
Dividing bothsides by 3
X = 18 × 5/ 3
X = 90 / 3
X = 30
Therefore.
The largest share = 30

A large tank of sterile water holds 200 gallons . It is leaking at an unknown rate. At 4:30 pm the tank had 137 gallons and at 7:00 pm the tank had 115 gallons. Assuming the tank was full when the leak began , write a function to estimate how much water is in the tank. now find the time at which the tank began leaking and the time at which the tank will be empty.
Answer:
1. 8.8 gallons per hour
2. 9:20 am
3. 8:04 am
Step-by-step explanation:
The tank lost 22 gallons of water in 150 minutes (2.5 hours)
This is a rate of 0.14666 gallons per minute or 8.8 gallons per hour
The function: 200 - 0.147(x)
So at 4:30 pm, the tank lost 63 gallons. So at a rate of 8.8 gallons per hour, that means it has been leaking for 7.16 (.16 hours = 9.6 minutes) hours.
So it has been leaking since 9:20 am.
In order for it to completely empty, it needs to drain 115 gallons of water.
At a rate of 8.8 gallons per hour, that means it needs 13.068 hours or 13 hours and 4 minutes.
So it will be empty at 8:04 am.

Answer: (1, 18)
Step-by-step explanation:
Test each x, y pair.
Getting to the last one, plug in 1 for the x value.
y = 3 * (6 ^ x)
y = 3 * (6 ^ 1)
y = 3 * 6
y = 18

the circumference of a circle is always
2×pi×r
with r being the radius, which is always half of the diameter.
so, the circle X circumference is
pi×15
circle Y
pi×20
the difference is
20×pi - 15×pi = 5×pi
5×pi is half of 10×pi, which would be 10×3.1415... = 31.415...
half of that is about 15.7.
