a cylindrical tank of radius 2.5m and height 1.6m initially contains water of depth of 20cm .water is pumped into the tank at the rate of 1.35litres per second.giving your answer in the nearest minute calculate the time in hours and minute it takes to fill the tank​

Answers

Answer 1
20cm=0.2m
1.6m-0.2m=1.4m
radius=2.5, area of circle=19.635m^2
19.635m^2x1.4m=27.489m^3
1litre=0.001m^3
1.35litres=0.00135m^3
27.489^3/0.00135m^3=20362s
60s=1min
20362s/60s=339.37min
=5 hours and 39 minutes

You deposit $6000 in an account earning 8% interest compounded monthly. How much will you have in the account in 15 years?

Answers

Answer:

13,200

Step-by-step explanation:

6000/100=60

60x8=480

480x15=7,200

6,000+7,200=13,200

If the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.

What is compound interest?

Compound interest is the interest calculated on the principal and the aggregate interest. It may be copounded annually,semi annually, monthly, bimonthly,etc.

How to calculate interest?

We have been given that the deposit is $6000,rate is 8% which is compounded monthly.

So effective rate of interest will be 8/1200=0.0067.

n will be 15*12=180

The sum after 15 years=6000[tex](1+0.0067)^{180}[/tex]

S=6000[tex](1+0.0067)^{180}[/tex]

Take log both sides.

log S=log 6000[tex](1+0.0067)^{180}[/tex]

log S=log 6000+log [tex](1+0.0067)^{180}[/tex]

log S=log 6000+180 log (1.0067)

log S=3.7781+180*0.0029

log S=3.7781+0.522

log S=4.3001

S=AL (4.3001)

S=19957.218

Hence if the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.

Kyle wants to find out how many textbooks his class has in total. He has discovered
that each student has an average of 5 textbooks. There are 30 people in his class. How many
textbooks does his class have in total?

Answers

Answer: His class has approximately 150 textbooks in total

Explanation: Because it is given that each student carries about 5 textbooks, with 30 students in the class, the equation would be 5 • 30 = 150. Some students may have more, while others may have less, so the average is given as 5 in order to simplify the equation.

What is an algebraic expression?

Algebraic expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine an algebraic expression for "2 less than the product of 3 and a number x"

Here, the product of 3 and a number x

⇒ 3x

Therefore, 2 is less than the product of 3, and a number x as

⇒ 3x -2

Hence, the algebraic expression is 3x -2.

original number?
E. 44%
F. 40%
G. 20%
H. 10%

Answers

F because its common sense its 40% greater

Answer:

44%

Step-by-step explanation:

Suppose the original number is 100.

It is increased by 20 %, so the result will be 120.

The resulting number is again increased by 20%, which is increased by 120 *20/100, which is increased by 24. The final result will be 120+24 that is 144.

The final result is increased by 44 compared to the original number 100.

So, increase by 44%.

Answer:

∠ BOF = 32°

Step-by-step explanation:

Since AB is a straight line, then

∠ AOE + ∠ EOD + ∠ DOE = 180° , substitute values

90 + x + 8 + 2x - 8 = 180 , that is

3x + 90 = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

Thus

∠ DOB = 2x - 8 = 2(30) - 8 = 60 - 8 = 52°

∠ COF = 4x - 24 = 4(30) - 24 = 120 - 24 = 96°

∠ AOC = ∠ DOB ( vertical angles ), thus

y = 52, then

∠ BOF = 180° - (96 + 52)° = 180° - 148° = 32° ( angles on a straight line )

A landscaping company is laying a triangular flower bed. The height of the trangle is 15ft. What lengths of the base will make the area at least 210ft squared?

Answers

Answer:

28 ft

Step-by-step explanation:

The height of the triangle = 15 ft

The least required area A = 210 ft^2

We know that the area of a triangle = 1/2bh

Where

b is the base

h is the height

Substituting, we have

210 = 1/2 x b x 15

210 = 15/2 x b

420/15 = b

b = 28 ft
