Answer: A cylindrical water storage tank has an inside base radius of 7m and depth of 11 m. ... Let the depth of the tank be h metres.
Step-by-step explanation:
Answer:
the radius is 10 m apprx
Step-by-step explanation:
height of the cylinder = [tex]\pi r^{2} h[/tex] = 4082 [tex]m^3[/tex]
then [tex]r^{2}= \frac{4082}{13\pi } = 99.9493[/tex]
r= [tex]\sqrt{99.9493}[/tex] =10.0 m

For an activity in class, students used pieces of string to measure roads on a map. They used a map scale to determine the
distance between two cities. One group measured the distance between Fort Myers and Miami on a Florida state map. The string
distance was 7 inches, which represents a real-life distance of about 154 miles. Another group measured the distance between
Tampa and Orlando on the same map and found that distance to be 4 inches.
The students need to figure out what the distance is from Tampa to Orlando. They begin to set up the following table. Complete the
table for them.
Inches
Miles
What is the real-life distance to the nearest mile between Tampa and Orlando?
2 3 4 5 6
Next
Answer:
The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
Step-by-step explanation:
String distance between Fort Myers and Miami = 7 inches
A real life distance between Fort Myers and Miami = 154 miles
So, 7 inches = 154 miles
[tex]1 inch = \frac{154}{7}=22 miles[/tex]
Scale : 1 inch = 22 miles
String distance between Tampa and Orlando = 4 inches
Using scale
The real-life distance to the nearest mile between Tampa and Orlando = [tex]4 \times 22 = 88 miles[/tex]
Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Once a large pink ribbon, the sign of the fight against breast cancer, was erected out of pink post-it notes on a billboard. If the area of the rectangular billboard covered by the ribbon was approximately 3420 square feet, and the width of the billboard was approximately 57 feet, what was the height of this billboard?
Answer:
60 feet
Step-by-step explanation:
The shape of a billboard = Rectangle
Area of a rectangle = Length(Height) × Width
Area = 3420 square feet
Width = 57 feet
Height = Area of the billboard/Width
Height = 3420 ft²/57 ft
Height = 60 feet
Therefore, the height of the billboard is 60 feet

Answer:
look below.
Step-by-step explanation:
When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:
1) -2j + 6 = 2j - 8
-2j - 2j = - 8 - 6
-4j/4 = -14/4
j = 14/4
j = 7/2
2) 4h + 6 = 2h - 8
4h - 2h = - 8 - 6
2h/2 = - 14/2
h = -7
3) 9w + 9 = 3w - 15
9w - 3w = - 15 - 9
6w/6 = -24/6
w = -4
4) 45 = -9(e + 8)
45 = -9e - 72
45 + 72 = -9e
117/-9 = e
e = -13
5) 35 = -7t
35/-7 = t
t = -5
6) 12k + 13 = 8k + 33
12k - 8k = 33 - 13
4k/4 = 20/4
k = 5

The coordinate grid shows points A through K Which points are solutions to the system of inequalities listed below
2x+y<10
2x-4y<8
Answer:
Step-by-step explanation:
Given the simultaneous inequality
2x+y<10 ....... 1
2x-4y<8 ....... 2
Subtract both equation from each other
(2x-2x)+(y-(-4y))<10-8
0+5y<2
y < 2/5
y < 0.4
Substitute the given value of y into 1;
2x+y<10
2x + 2/5 < 10
2x < 10 - 2/5
2x < 48/5
10x < 48
x < 4.8
Hence the solution to the inequality expressions is (4.8, 0.4)

What is the result when 3x^3-x^2-4x+20 is divided by x+2?
Answer:x=-32
Step-by-step explanation:
Answer
[tex]3x ^{2} - 6x + 8 + \frac{4}{x + 2} [/tex]
Step-by-step explanation:
use synthetic division-
1. but all the coefficients in a box
2. put the divisor term equal to 0 so... x+2=0 ,x would have to equal negative 2 x= -2
3. drop the first coefficient
4. multiply the number outside the box by the number you just dropped and put it under the second coefficient. then subtract
5. keep repeating steps four
6. once youre done the last term below the box is your remainder and should be written as +remainder over divisor which in this case is x-2
7. everything is backwards soo the 8 would be your constant, the -6 is your x and 3 is your x^2 term.

You start 3 feet from the motion detector and walk
slowly away from the motion detector.
(it’s A.)
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Starting 3 feet from the motion detector, you will be at the point (0, 3) on the graph.
A normal walking speed is about 3 mph, or about 4.4 feet per second. So, walking slowly may be something less than 2 feet per second. In the attached graph, we show a walking speed of about 4 feet in 10 seconds, a really slow speed. Since you're walking away, the distance is increasing with time.

An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane. Which graph represents the solution to the inequality that finds the number of tickets the airline can still sell?
Answer:
C
Step-by-step explanation:
The number of tickets the airline still sells will be 88. Then the correct graph is A.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
An airplane can seat up to 175 passengers.
The airline has already sold 87 tickets for a flight on the airplane.
Then the graph represents the solution to the inequality that the number of tickets the airline still sells will be
Let x be the number of the ticket which need to sell. Then the inequality equation will be
x + 87 ≤ 175
x ≤ 175 - 87
x ≤ 88
Thus, the correct option is A.

Algebra I
FactoringFinding roots of quadraticsStep-by-step explanation:
Step 1: Define
y = 2x² - 6x - 8
0 = 2x² - 6x - 8
Step 2: Find roots
Factor 2: 0 = 2(x² - 3x - 4)Factor: 0 = 2(x - 4)(x + 1)Find roots: x = -1, 4And we have our final answer!
Answer:
first take 2 out of the equation
y=2(x^2-3x-4)
then factor
y=2(x-4)(x+1)
then solve
(x-4)=0 . (x+1)=0

If JL = 16, KM = 4x-1, and KM is a perpendicular bisector of JL, determine which of the following values are correct. Select ALL that apply.
A.x = 3
B.JK = 11
C.KM = 15
D.KL = 17
E.Perimeter of triangle KLM = 22
F.Perimeter or triangle JKL = 50
*see attachment for diagram
Answer:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50
Step-by-step explanation:
Given:
JL = 16,
KM = 4x-1
JK = 6x - 7
KL = 5x - 3
✔️Thus, let's find the value of x
Since KM is a perpendicular bisector of JL, it means JM = LM = ½*16 = 8
KM in ∆KJM is equal to KM in ∆KLM.
The angles opposite the two corresponding congruent sides in both triangles are also congruent to each other. Therefore, the third corresponding side and angles would be congruent to each other.
Thus:
JK = KL
6x - 7 = 5x - 3 (substitution)
Collect like terms
6x - 5x = 7 - 3
x = 4
✔️Find JK:
JK = 6x - 7
Plug in the value of x
JK = 6(4) - 7
JK = 24 - 7
JK = 17
✔️Find KM:
KM = 4x - 1
Plug in the value of x
KM = 4(4) - 1
KM = 16 - 1
KM = 15
✔️Find KL:
KL = 5x - 3
Plug in the value of x
KL = 5(4) - 3
KL = 20 - 3
KL = 17
✔️Find the Perimeter of ∆KLM:
Perimeter of ∆KLM = KM + KL + LM
= 15 + 17 + 8
= 40
✔️Find the Perimeter of JKL:
Perimeter of ∆JKL = JK + KL + JL
= 17 + 17 + 16
= 50.
The correct values are:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50
