5. A cylindrical pillar is 50 cm in diameter and 3.5 m in height. Find the cost of painting
the curved surface of the pillar at the rate of 12.50 per m.
Answer:
The cost of painting the curved surface of pillar is: 68.69
Step-by-step explanation:
Given that
Diameter of pillar = d = 50 cm
As the height is in meters and we have to find the cost in per square meter, we have to convert cm into meters.
So,
d = 50/100 = 0.50 m
Now the radius will be:
[tex]r = \frac{d}{2} = \frac{0.50}{2} = 0.25m[/tex]
Also
Height = 3.5m
The curved surface area of cylinder is given by:
[tex]CSA = 2\pi rh[/tex]
Putting the values
[tex]CSA = 2 * 3.14 * 0.25 * 3.5 = 5.495\ m^2[/tex]
It is given that the cost per square meter is 12.50
The total cost for 5.495 m^2 will be: 12.50 * 5.495 = 68.6875
Rounding off to nearest hundredth: 68.69
Hence,
The cost of painting the curved surface of pillar is: 68.69

Solve for x using the
distributive property
4(x + 2) = 4
Answer:
-1
Step-by-step explanation:
4x + 8 = 4
subtract 8 from each side
4x = -4
divide each side by -4
x= -1
Answer:
x = -1
Step-by-step explanation:
You would first multiply 4 with is the first number by x and 2. You would get 4x+8. The you would subtract 8 by both sides. 4x = -4. The you would divide 4 by -4. Which will get you -1.

What is the slope?
Simplify your answer and write it as a proper fraction, improper fraction, or integer,
Answer:
[tex]2[/tex]
Step-by-step explanation:
For this I would find two friendly points like (60,10) and (70,30). Now we will plug in for the slope-intercept formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
So...
[tex]y_2=30\\y_1=10\\x_2=70\\x_1=60[/tex]
Now we plug in and solve...
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{30-10}{70-60}\\m=\frac{20}{10}\\m=\frac{2}{1}=2[/tex]
So the slope will be 2.
Which number line shows the solution of -5 + 10 > -15?
Which of the following are like terms?
15y4,16y3
8y6, 6y8
16y2, 12y
13y25, 2y25
Answer: D) 13y^25 and 2y^25
Like terms involve the same variables, and each of those variables must have the same exponents.
Another example of a pair of like terms would be 5x^3y^2 and 7x^3y^2. Both involve the variable portion "x^3y^2" which we can replace with another variable, say the variable z. That means 5x^3y^2 becomes 5z and 7x^3y^2 becomes 7z. After getting to 5z and 7z, it becomes more clear we have like terms.

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange.Let B = the event of getting a blue jelly beanLet G = the event of getting a green jelly bean.Let O = the event of getting an orange jelly bean.Let P = the event of getting a purple jelly bean.Let R = the event of getting a red jelly bean.Let Y = the event of getting a yellow jelly bean.What is the probability of drawing a red jelly bean in the first draw WITHOUT replacing the red jelly bean, then choosing a blue jelly bean in the second draw?Use 4 decimal places for this problem. Do not round your answers for intermediate steps, only for the final answer.
Answer:
[tex]P(R\ and\ B) = 0.0256[/tex]
Step-by-step explanation:
Given
[tex]Red = 22[/tex]
[tex]Yellow = 38[/tex]
[tex]Green = 20[/tex]
[tex]Purple = 28[/tex]
[tex]Blue = 26[/tex]
[tex]Orange = 16[/tex]
Required
Determine the probability of red then blue jelly? i.e. P(R and B)
From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean
So, we have:
[tex]P(R\ and\ B) = P(R)\ and\ P(B)[/tex]
This is then solved further as:
[tex]P(R\ and\ B) = P(R)\ *\ P(B)[/tex]
[tex]P(R\ and\ B) = \frac{n(R)}{Total}\ *\frac{n(B)}{Total - 1}[/tex]
The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean
The equation becomes:
[tex]P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{150- 1}[/tex]
[tex]P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{149}[/tex]
[tex]P(R\ and\ B) = \frac{22*26}{150*149}[/tex]
[tex]P(R\ and\ B) = \frac{572}{22350}[/tex]
[tex]P(R\ and\ B) = 0.02559284116[/tex]
[tex]P(R\ and\ B) = 0.0256[/tex]

Marshall is comparing introductory rates for two different video streaming services. He can pay $22.50 for the first 3 months with Watch It Now, or he can pay $43.50 for the first 6 months with Megaflicks. Which service's introductory rate is a better deal?
Answer:
megaflicks would be the better deal
Step-by-step explanation:
22.50 divided into 3 months would be 7.50
43.50 divided into 6 months would be 7.25
Meaning that you'd pay less every month with megaflicks.

much milk to order
Each elf will get a 1
cup of milk. If there
are 328 elves, how
many quarts of milk
need to be ordered?
Answer:
1312 quarts
Step-by-step explanation:
1 cup = 4 quarts
328 ^ 4 = 1312
Answer:
82 quartsStep-by-step explanation:
Each elf gets 1 cup of milk
Number of elves = 328
1 quart = 4 cups ⇒ 1 cup = 1/4 quart
Required volume of milk is:
328 cups = 328*1/4 quarts = 82 quarts82 quarts of milk to be ordered
Kamal spent 40% of his income. He
deposited Rs. 400 in a bank and
was left with Rs. 500. What is his
income?
(a) Rs. 1200
(b) Rs. 1450
(c) Rs. 1500
(d) Rs. 1680
an
Answer:
(c) Rs. 1500
Step-by-step explanation:
Percentages
It's given Kamal spent 40% of his income. With the remaining 60%, he deposited Rs. 400 in a bank and still has Rs. 500 left.
This means Rs. 400 + Rs. 500= Rs. 900 is 60% if his income.
The 100% of his income is calculated as a percent proportion:
If 60% is Rs. 900, then 100% is:
[tex]\displaystyle \frac{900}{60}*100=1500[/tex]
Thus, Kamal's income is Rs. 1500. Correct choice: (c) Rs. 1500

What is the range of the graph?
Answer:
[tex]-5 \leq y \leq 5[/tex]
Step-by-step explanation:
Just find the minimum point and the maximum point of the graph in the y-axis.
The minimum value is -5 and the maximum value is 5,
so the y- value of the graph can be any point between -5 and 5 (including -5 and 5).
And the range of the graph is greater or equal to -5 and lesser or equal to 5.
