The height of the cone is 24 cm.
How is the slant height calculated?The distance along the curved surface, measured from the edge at the top to a point on the circumference of the circle at the base, is known as the slant height of an object (such as a cone or pyramid). In other words, the slant height, represented either as s or l, is the shortest distance that may be traveled along the surface of the solid.
Slant height(l)=26cm
Radius(r)=10cm
It is known that, [tex]l^{2}=r^{2}+h^{2}[/tex]
Here, h is the height of the cone.
On substituting the values,
[tex]26^{2}= 10^{2}+h^{2}[/tex]
[tex]\\676=100+h^{2}\\[/tex]
[tex]h^{2}=676-100\\[/tex]

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.

a sweet factory produces 5 different chocolate bars. the different flavors are always produced in the same proportions, for every 4 coconut flavored bars 5 honeycomb 6 orange and 4 strawberry
what is the total number of chocolate bars if there are:
a) 280 orange flavored bars?
b) 960 coconut flavored bars?
c) 79 coffee flavored bars?
a. There are 933 chocolate bars
b. There are 1200 chocolate bars
c. There are 1580 chocolate bars
How to calculate the number of chocolate barsSince there are 5 different flavors,
let
x = orange flavored bars, y = coconut flavored bars, z = coffee flavored bars, a = strawberry flavored bars and b = honeycomb flavored bars and X = total number of barsSince the different flavors are always produced in the same proportions, for every 4 coconut flavored bars 5 honeycomb 6 orange 1 coffee and 4 strawberry
So, the ratio of their proportions are x:y:z:a:b = 6:4:2:1:5
So, the total ratio is T = 6 + 4 + 1 + 4 + 5 = 20
a. What is the total number of chocolate bars if there are 280 orange flavored bars?Since we have 6 orange flavored bars, the ratio of orange flavored bars to total is 6/20
So, the amount of orange flavored bars is x = 6/20 × X
Making X subject of the formula, we have
X = 20x/6
So, if there are 280 orange bars, there will be
X = 20x/6
X = 20 × 280/6
X = 5600/6
X = 933.33
X ≅ 933 chocolate bars
So, there are 933 chocolate bars
b. What is the total number of chocolate bars if there are 960 coconut flavored bars?Since we have 4 coconut flavored bars, the ratio of coconut flavored bars to total is 4/20
So, the amount of coconut flavored bars is y = 4/20 × X
Making X subject of the formula, we have
X = 20y/4
So, if there are 960 coconut flavored bars, there will be
X = 20y/6
X = 20 × 960/4
X = 5 × 240
X = 1200 chocolate bars
So, there are 1200 chocolate bars
c. What is the total number of chocolate bars if there are 79 coffee flavored bars?Since we have 1 coffee flavored bars, the ratio of coffee flavored bars to total is 1/20
So, the amount of coconut flavored bars is z = 1/20 × X
Making X subject of the formula, we have
X = 20z
So, if there are 79 coffee flavored bars, there will be
X = 20z
X = 20 × 79
X = 1580 chocolate bars
So, there are 1580 chocolate bars

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

When David was asked how old he was, he said " I'm three times younger than my dad, but twice as old as Rebecca. " Then little Rebecca ran up to him and declared "i am 30 years younger than my dad". How old is David
Using a system of equations, it is found that David is 12 years old.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The variables are given as follows:
Variable x: David's age.Variable y: Dad's age.Variable z: Rebecca's age.David is three times younger than the dad and twice as old as Rebecca, then:
x = y/3 -> y = 3x.x = 2z.Rebecca is 30 years younger than the dad, hence:
z = y - 30.
Then, since x = 2z and z = y - 30 and y = 3x, we solve for x to find David's age.
x = 2(y - 30)
x = 2(3x - 30)
x = 6x - 60
5x = 60
x = 60/5
x = 12.
David is 12 years old.

Which measurement is closest to the difference between the circumference of circle X and the
circumference of circle Y in centimeters?
A 15.7 cm
B 7,85 cm

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...

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

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
