Answer:

678.24

Step-by-step explanation:

First, we have to find the area of 1 cylinder(pi x r^2 x h), which i got as 226.08 then we multiply by 3 because there are 3 cylinders. 226.08 x 3 = 678.24

Answer: Hope this helps you!

Step-by-step explanation:

First, I started off with the equation of the area of a cylinder

Area = π * radius^2 * height

Now I will go on and substitute

Area = 3.14 * 3^2 * 8

And now I will start solving

Area = 3.14 * 3^2 * 8

(3^2 = 3*3 = 9)

Area = 3.14 * 9 * 8

(9*8 = 72)

Area = 3.14 * 72

Area = 226.08

The area of 1 cylinder is 226.08, however we need to find the area of the whole composite figure which is made up of 3 cylinders.

226.08 * 3 = 678.24

Answer: G.

Step-by-step explanation:

The formula for a circle's circumference is C = 2[tex]\pi r[/tex]

r = radius

We know the rectangle ABCD has a perimeter of 72 cm.

The rectangle is divided into 6 perimeter sides: AP, PB, BC, CQ, QD, and DA.

If we divide 6 sides to the rectangle's perimeter, we can calculate the length of one side.

72 / 6 cm = 12 cm

A side of the perimeter of the rectangle ABCD is equal to 12 cm, which means PQ, the radius of the circle is equal to 12 cm.

C = 2[tex]\pi r[/tex]

radius = 12 cm

C = 2[tex]\pi[/tex] * 12 cm

C = 2 * 12 * Pi cm

C = 24[tex]\pi[/tex]

Answer = G.

Hope I Helped!

Answer:

24pi (G)

Step-by-step explanation:

This question might seem hard at first, but we know one crucial piece of information- line PQ- is the circle's radius. We also know that Q "fits perfectly" on line DC, and that angle QPB is a right angle. Since the line is straight and passes through THE MIDDLe of the rectangle, we can assume that line PQ divides the rectangle into two squares. Since squares have 4 corresponding sides, or sides with the same length, we can rewrite the equation as x+x+2x+2x, which is 6x = 72. Apply and find your answer.

EASIER EXPLANATION:

the radius is at a right angle, meaning it divides the rectangle into two squares.

It is stated that the perimeter of the rectangle is 72, meaning if we write it into an equation where x = short sides and y = long sides.

x+x+y+y = 72

However, the long sides really equal 2x, so we can rewrite the equation

x+x+2x+2x = 72

Simplify

X+x+x+x+x+x = 72

Simplify more

6x = 72

solve

x = 12

We also know that 2x is the dimeter, which is 24.

Apply to the circumference equation

C= Dpi

Since all our answeres are in pi form, we don't need to solve

Answer:

68.42

Step-by-step explanation:

We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 - 146.2 to get 68.42. Hope this helps!

You divide both the numerator and the denominator by the same number until they can't be reduced any further.

Answer:

Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

Step-by-step explanation:

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.

242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51  1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10.      72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.

1 month is aprox. 30 days, so

To find john's daily salary:

For a month, the salary is 4,410 rupees, so for a day how much?

days     salary

30          4,410    (This is how I learnt to solve these kind of problems)

1               ?

Then you crisscross the equation which becomes

4,410/30=147 rupees

To find weekly salary:

we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?

You multiply the salary for one day and the number of days: 147×7=1,029 rupees

To find salary for a year (annual):

we now know the salary for one day so we can say:  For a day, the salary is 147 rupees, so for 365 days (1 year) how much?

You multiply the salary for one day and the number of days: 147×365=53,655 rupees

Answer:

No Solutions

Step-by-step explanation:

Hello!

We can approach this system using the Elimination method. Since the coefficients of the the x terms are the same, we should vertically subtract the two equations.

Since 0 does not equal to -11, there are no solutions to the system.

We can also look at this graphically. The two lines have the same slope but different y-intercepts, meaning that they would be parallel lines with no intersection. If there is no intersection, there are no solutions.

Answer:

23

Step-by-step explanation:

To find the Greatest Common Factor, or GCF, we need to factor the first 2 numbers and then find the greatest number that is both present in the prime factorization of both numbers.

253 = 1 * 11 * 23

345 = 3 * 5 * 23

Since 23 is both present in both numbers and is the greatest, the GCF of 253 and 345 is 23.

(i) Equation :  y = 6.25x + 65

(ii) Price of each ticket : $6.25

(iii) Money originally in the box : $65

Explanation:

Here from table, identify the coordinates given.

Coordinates:

Find slope:

[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]

[tex]\rightarrow \sf slope \ (m) : \dfrac{146.25-108.75}{13-7} = 6.25[/tex]

Slope is also the price of each ticket which is $6.25

Equation:

[tex]\sf y - y_1 = m(x - x_1)[/tex]

[tex]\rightarrow \sf y - 108.75 = 6.25(x - 7)[/tex]

[tex]\rightarrow \sf y - 108.75 = 6.25x - 43.75[/tex]

[tex]\rightarrow \sf y = 6.25x - 43.75 + 108.75[/tex]

[tex]\rightarrow \sf y = 6.25x +65[/tex]

To find the amount of money in the box originally, insert x which represents number of tickets sold as 0.

Originally amount of money:

[tex]\rightarrow \sf y = 6.25(0) +65[/tex]

[tex]\rightarrow \sf y = 65[/tex]

Hence, there were $65 in the box before any tickets were sold.

Answer:

A

Step-by-step explanation:

2x² + 5x = 12

2x² + 5x - 12 = 0

x² + 5x - 24 = 0

factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3

2x² - 3x + 8x - 12 = 0

split the equation and factor

2x² - 3x = 0 ||| 8x - 12 = 0

x(2x - 3) ||| 4(2x - 3)

therefore the pair is (2x - 3)(x + 4)

2x - 3 = 0

2x = 3

x = 3/2

or

x + 4 = 0

x = -4

Answer:

x =5.25

Step-by-step explanation:

Comment

So you want to find x? If the scale factor is 1.75 it means that you multiply whatever dimension on Figure A by 1.75 to get the corresponding dimension on B.

Formula

x = 1.75 * 3

Solution

x = 1.75 *  3

x = 5.25
