Given :
A cuboid shaped tank with sides 3.2 cm , 2.8 cm and 1.6 cm.
To Find :
The volume of the tank.
Solution :
We know, volume of a cuboid is given by product of its sides or :
[tex]V = l\times b \times h\\\\V = 3.2 \times 2.8 \times 1.6 \ cm^3\\\\V = 14.336 \ cm^3[/tex]
Therefore, the volume of the tank is 14.336 cm³ .

Answers
Answer: what’s the answer ?
Step-by-step explanation:
If each cylinder is 4 feet tall and has a diameter of 1 foot then the amount of sand needed to fill the cylinders is 19 cubic feet.
Given that there are 6 cylindrical posts protecting the equipment
To find tge amount of sand needed for cylinders,
We need to find the volume of each cylinder.
The cylinder is 4 feet tall and has a diameter of 1 foot,
Height is 4 feet
Diameter is 1 foot and radius is 1/2 feet.
Volume of cylinder = πr²h
=3.14×(1/4)(4)
=3.142 cubic feet.
As there are six cylinders.
Multiply 6 with 3.142
Amount of sand needed = 6×3.142
= 18.852 cubic feet.

What is P(divisor of 63)? Choose the closest answer.
Answers
Answer:
the divisors of 63 are
Step-by-step explanation:
1,3,7,9,21,63
Answer:
Fraction Form: 2/6 or 1/3
or Decimal Form: .333
or Percent Form: 33.333?%
Step-by-step explanation:
The divisors of 63 that are 1-6 is 1 and 3
So there are TWO numbers out of SIX.
We would turn that into the fraction 2/6 and then simplify (optional) it to 1/3.
Then we use 2/6 to convert it to multiple forms if needed.
The spinner shown has congruent sections. The spinner is spun 63 times. What is a reasonable prediction for the number of times the spinner will land on a section that is shaded red?
Answers
Answer:
36 times
Step-by-step explanation:
Given
[tex]Red = 4[/tex]
[tex]Total = 7[/tex]
[tex]n = 63[/tex]
See attachment
Required
Predicted number of times to land on red
First, we calculate the probability of landing on red
[tex]Pr = \frac{Red}{Total}[/tex]
[tex]Pr = \frac{4}{7}[/tex]
The predicted number of red is the =n calculated as:
[tex]Red = Pr * n[/tex]
[tex]Red = \frac{4}{7}*63[/tex]
[tex]Red = 4 * 9[/tex]

What is the radius of this circle of the circumference is 18pi cm?
Answers
Answer:
r=9cm
Step-by-step explanation:
C= 2pi r = 18 pi so
2r =18 so r = 18/2=9
Answer:
[tex]r=9[/tex]
Step-by-step explanation:
The equation to find the circumference of a circle when given the radius is the following,
[tex]C=r(\pi)(r)[/tex]
There (C) represents the circumference, (r) represents the radius, and ([tex]\pi[/tex]) represents the irrational numbers (3.1415...)
Substitute in the given values and backsolve for the radius,
[tex]18(\pi)=2(\pi)(r)[/tex]
Inverse operations,
[tex]18(\pi)=2(\pi)(r)[/tex]
[tex]9=r[/tex]
A group of friends wants to go to the amusement park. They have $112.50 to spend on parking and admission. Parking is $20, and tickets cost $18.50 per person, including tax. How many people can go to the amusement park?
Answers
Answer:
The Answer Is Five
Step-by-step explanation:
Because When You Take 20 From 112.50 Its 92.5 Then You Divide By 18.50 It Equals 5
They have no more than $125 to spend
Parking 15.00, Tickets 12.50 per person
$15 + $12.50p ≤ $125
p = 110/12.5 ≤ 8.8
p ≤ 8, THEREFORE 8
Note: $15 + 9($12.50) =$127.50
A radio station broadcasts a signal over an area with a 120-mile diameter. The population density of the area is 100 people per square mile.
How many people are within receiving distance of the broadcast signal?
Use 3.14 for pi.
Answers
Answer:
1,130,400 people
Step-by-step explanation:
Find the area of the broadcasting area, using the circle area formula.
Since the diameter is 120 miles, the radius will be 60 miles.
Use the circle area formula, plug in 60 as r, and plug in 3.14 as pi:
A = [tex]\pi[/tex]r²
A = (3.14)(60²)
A = 11304
So, the area is 11304 square miles
To find how many people are in receiving distance, multiply this by 100, since there are 100 people per square mile.
11304(100)
= 1,130,400
So, 1,130,400 people are within receiving distance of the signal.

After 4 years eldi will be three times the age he had 10 years ago. Using algebra find the age of eldi
Answers
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .

A garden hose is leaking 1 liter of water every 1/8 hour. How many liters of water will it leak in 3 ¾ hours? *
Answers
Therefore, 1/8 of 60 is 7.5, meaning, 1 litre of water is leaked every 7.5 minutes.
3¾ hours is 60 x 3 + 60/4
= 180 + 15
= 195 minutes
As 3 ¾ hours is 195 minutes and 1 litre is leaked every 7.5 minutes, we have to divide 195 by 7.5.
195/7.5 = 26
Therefore, the garden hose will leak 26 litres in 3 ¾ hours.

sin θ = Opposite/Hypotenuse
sin θ = 10/15
θ = arc sin ( 10/15)
θ = 41.810314896°
θ = Approximately to 1 decimal place = 41.8°
