Step-by-step explanation:
1/3 nr^2h = volume of a cone
1/3 x 22/7 x 14 x r^2 = 440
r^2 = 440 x 3 x 7/22 x 1/14
r^2 = 30
r = 30
r = 5
The base diameter to the nearest whole number is 11cm
The volume of a coneThe formula for calculating the volume of a cone is expressed as:
V =1/3πr²h
Given the folllowing parameters
V = 440cm^3
h = 14cm
Substitute the given parameters
440 = 1/3(22/7) * 14r²
440 = 44/3 * r²
10 = r²/3
r² = 30
r = 5.5cm
d = 11cm
Hence the base diameter to the nearest whole number is 11cm

If 18% of all Americans are underweight, find the probability that two randomly selected Americans will both be underweight.
Answer:
the answer is no they will not be all underweight, they will have a 5% chance of being underweight. They will probably be overweight if you just pick 3.
Step-by-step explanation:
The probability of two Americans will be underweight will be 0.0324.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given,
Probability of selecting one American will be underweight = 18% = 0.18
Probability of the second one will be underweight = 0.18
Probability of both will be underweight = 0.18² = 0.0324
Hence "The probability of two Americans will be underweight will be 0.0324".The probability

*20 POINTS* find the value of x ? x = ___
Answer:
5
Step-by-step explanation:
find the measure of angle A
Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
Answer:
The measure of angle A is 30 degrees.
Step-by-step explanation:
Since all triangles are equal to 180 degrees, you take set up an equation where u add 2x and 3x to get 5x and u add that to 130 and set it equal to 180
2x+3x+130=180 ( combine like terms)
5x=50 (subtract 130 from both sides to isolate our variable which is x)
x=10 (divide both sides by 5 to get rid completly isolate our variable)
Now we know x=10 you can plug that in as our x value so 3x becomes 3*10 which equals 30 which is your answer.
What are the ordered pairs of the solutions for this system of equations?
Answer:
( 4, 11 ) , ( - 4, 27 )
Step-by-step explanation:
f(x) = x² - 2x + 3
f(x) = - 2x + 19
x² - 2x + 3 = - 2x + 19
x² - 16 = 0
( x + 4 )( x - 4 ) = 0
[tex]x_{1}[/tex] = - 4
[tex]x_{2}[/tex] = 4
f(x) = [tex]y_{1}[/tex] = - 2( - 4 ) + 19 = 27
[tex]y_{1}[/tex] = 27
f(x) = [tex]y_{2}[/tex] = - 2( 4 ) + 19 = 11
[tex]y_{2}[/tex] = 11

Answer:
cylinder and cone256π ≈ 804.25 m³Step-by-step explanation:
The figure is a composite of a cylinder added to a cone.
The height of the conical portion is (20 m -14 m) = 6 m. We know that the volume of a cone is 1/3 the volume of a cylinder with the same dimensions. Another way to think of that is the volume of a cone is the same as that of a cylinder of 1/3 the height.
So, this figure has a volume equivalent to that of a 14 m tall cylinder topped by a (6 m)/3 = 2 m tall cylinder. Effectively, we're seeking the volume of a cylinder of radius 4 m and height 16 m.
V = πr²h
V = π(4 m)²(16 m) = 256π m³ ≈ 804.248 m³
The volume of the "silo" is 256π ≈ 804.25 m³.
_____
If you use 3.14 for π, you will get 803.84 m³.

Answer:
172.12 sq in
Step-by-step explanation:
The figure is comprised of a semicircle, and 2 rectangles
Area of semicircle = 1/2(3.14)4^2 = 25.12
Area of rectangle with length of 9 and width of 7 = 7(9) = 63
Area of rectangle with length of 14 and width of 6 = 6(14) = 84
Total area = 25.12 + 63 + 84 = 172.12 sq in
Use the formula to figure out the area. Calculate your answer to the nearest hundredth.

she finds a hotel that charges 84 euros per night, she thinks this will be about £100. Is she right?
Answer:
she is wrong
Step-by-step explanation:
Using the conversion rate
1 Euro equals =0.87 Pound sterling
84 euros = x
Cross multiply
1 * x = 0.87 * 84
x = 0.87 * 84
x = 73.08 pounds
Since 84 euros is not up to 100pounds,. Hence she is wrong
