A completely full cylindrical storage tank of Ski with a diameter of 60 feet and a
height of 50 feet sprung a leak. You are able to catch the liquid in rectangular prisms
with the dimensions 5ft by 6ft by 10ft. How many rectangular prisms are needed?
Justify your answer by writing sentences and showing your work.
Answer:
471Step-by-step explanation:
Volume of liquid in the tank:
V = πr²h = πd²h/4V = 3.14*60²*50/4 = 141300 ft³Volume of each prism:
V = lwh V = 5*6*10 = 300 ft³Number of prisms needed:
141300/300 = 471At 12:15, the end of the minute hand of a clock is 8 feet above the ground. At 12:30, it is 6.5 feet off the ground How long is the minute hand of the clock? And How high is the center of the clock from the ground
Answer:
Length of minutes hand= 1.5 feet
Height of the center of the clock from the ground= 8 feet
Step-by-step explanation:
At 12:15, the end of the minute hand of a clock is 8 feet above the ground.
At 12:15 the minutes hand is making a radius along the diameter of the clock which means it is at the center of the clock. In other the center of the clock is 8 feet above the ground.
At 12:30, it is 6.5 feet off the ground .
This tells length of the minutes hand the clock which is the distance from the ground minus the distance off the ground
= 8-6.5= 1.5 feet
The center of the clock is 8 feet from the ground.
The length of the minute hand is 1.5ft, the distance of the center of the clock from the ground is 8ft
To solve this problem, we have to apply logical reasoning here.
Length of the Minute HandTo calculate the length of the minute hand, we just have to subtract or find the difference between the minute and from the ground at 12:30 to the minute hand at 12:15.
This will give us
[tex]12:15 - 12:30 = 8 - 6.5 = 1.5ft[/tex]
Distance of the Center of the clock from the groundThe distance of the center of the clock from the ground can be gotten from the distance from the ground at 12:15. This is because at 12:15, the minute hand is at the same horizontal line with the center of the clock and this makes the distance of the center of the clock from the ground is 8ft.
From the above,
The length of the minute hand is 1.5ft The distance of the center of the clock from the ground is 8ftLearn more on clocks here;

A padlock's combination is four digits long.
Please show your work
Answer:
10,000
Step-by-step explanation:
Highest 4 digit number: 9999
Lowest possibility: 0000
9999-0000=9999
The 0000 is 1 number
9999+1=10,000
Answer:
1000 possible combinations
Step-by-step explanation:
For the padlock combination code, each number can be one of 10 (0-9).
This means there are 10 possibilities for the first digit, 10 for the 2nd, 10 for the 3rd, and 10 for the 4th.
If we combine all these possibilities between the different digits we get:
10 x 10 x 10 x 10 = 1000 different combinations.

Arquimedes, Euclides e Ptolomeu têm, juntos, R$ 1 990,00. Arquimedes possui R$ 190,00 a mais do que Euclides e esse, dispõe de R$ 120,00 a mais do que Ptolomeu. Determine quantos reais cada um deles possui.
Responder:
Ptolomeu = 520
Euclides = 640
Arquimedes = 830
Explicação passo a passo:
Deixar :
Quantidade que Ptolomeu tem = x
Quantidade de Euclides = x + 120
Quantidade que Arquimedes tem = x + 120 + 190
Valor total que todos eles têm = $ 1990
Portanto,
x + x + 120 + x + 120 + 190 = 1990
3x + 430 = 1990
3x = 1990 - 430
3x = 1560
x = 520
Ptolomeu = 520
Euclides = 520 + 120 = 640
Arquimedes = 640 + 190 = 830

Solve the inequality.
6x + 10 + 10x < 4(4x + 3)
Answer:
X = all #'s
why?
6x+10+10x < 4(4x+3)
Combined liked terms
16x + 10 < 16x +12
you can see that there is X on both sides and the lowest one has a +10 and the highest has a +12 so it will always be greater by 2
Answer:
undeterminate (all real numbers are a solution)
Step-by-step explanation:
1) multiply 4 by 4x and 3
6x + 10 + 10x < 16x + 12
2) added up the terms with x
16x + 10 < 16x + 12
3) add at the two members -16x
10 < 12
4) notice the 10 is ever < 12, so the inhequality is undetermined

(-2,-5) = (x1,y1)
(18,-5) = (x2,y2)
Slope = [tex]\frac{-5+5}{18+2}[/tex]

Malik is solving the equation x2 – 10x – 11 = 0 using the complete the square method. Here is Malik's work: Line 1 p^2 -10p-11=0 Line 2 p^2 -10p+25=11+25 Line 3 (p-5)^2 =36 Line 4 p-5=36 or p-5=-36 Line 5 p=41 p=-31 Line 6 the solution is p=41 or p=-31 Malik checks his answer and realizes he has made a mistake. On which line did Malik make his mistake? Explain Malik's mistake using the complete the square method in 1-3 complete sentences.
Completing the square method rearranges the equation to have the
square of linear equation and constant on both sides of the equation.
Responses:
The mistake is made in line 4The mistake is in not taking the square root of both sidesWhich is the correct completing the square method?The given equation is; x² - 10·x - 11 = 0
Line 1: p² - 10·p - 11 = 0
Which gives;
p² - 10·p = 11
Adding 25 to both sides gives;
Line 2: p² - 10·p + 25 = 11 + 25
11 + 25 = 36
Factorizing p² - 10·p + 25 = (p - 5)·(p - 5) = (p - 5)²
Line 3: (p - 5)² = 36
Which gives;
p - 5 = ±√36
Line 4: p - 5 = √36 = 6 or p - 5 = -√36 = -6 (Line that has a mistake)
Line 5: p = 6 + 5 = 11, or p = -6 + 5 = -1
Line 6: p = 11 or p = -1
The line Malik made a mistake is on line 4The mistake made is that in line 4, the root of both sides of the equation, rather than only the left side of the equation is to be taken.The constant on the left and side is then subtracted from the positive
and negative value of the square root of the right hand side to give two
results.

Solve for x. please i need know
Answer:
x = 18
Step-by-step explanation:
Vertically opposite angles are equal.
x + x + x + 90 = 144
3x + 90 = 144
Subtract 90 from both sides
3x = 144 - 90
3x = 54
Divide both sides by 3

A cylinder has a height of 11 inches. Its volume is 4,973.76 cubic inches. What is the radius of the cylinder?
Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
12 inches
Step-by-step explanation:
Given data
Height= 11 inces
Volume= 4,973.76 cubic inches.
The expression for the volume of a cylinder is
V= πr^2h
substitute
4,973.76= 3.14*r^2*11
4,973.76= 34.54r^2
r^2= 4,973.76/ 34.54
r^2= 144
Square root both sides
r=√144
