Answer:
942m^2
Step-by-step explanation:
to find the answer you do pi * r^2 *h
pi is 3.14 r is 5 and h is 12= 3.14* 5^2 * 12
now you have 78.5*12
now you're left with your answer 942m^2

1/3 rd part of the length of a bamboo is coloured in red and 1/5th part of it is coloured green and the remaing is 14m is coloured in yellow. lets find the length f the bamboo (step by step)
[tex]\bold{\huge{\blue{\underline{ Solution }}}}[/tex]
[tex]\bold{\underline{ Given :- }}[/tex]
1/3rd part of the length of a bamboo is coloured with red and 1/5th part of it is coloured with green and the remaining is 14m is coloured with yellow.[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the total length of the bamboo[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
Let the total length of bamboo be x
According to the question,
[tex]\sf{\dfrac{ 1}{3}}{\sf{x +}}{\sf{\dfrac{ 1}{5}}}{\sf{x + 14 = x }}[/tex]
[tex]\sf{\dfrac{ 1}{3}}{\sf{x + }}{\sf{\dfrac{1}{5}}}{\sf{x = x - 14 }}[/tex]
[tex]\sf{\dfrac{5x + 3x}{15}}{\sf{ = x - 14 }}[/tex]
[tex]\sf{ 5x + 3x = 15( x - 14 )}[/tex]
[tex]\sf{ 8x = 15x - 210 }[/tex]
[tex]\sf{ 210 = 15x - 8x}[/tex]
[tex]\sf{ 7x = 210 }[/tex]
[tex]\sf{ x = }{\sf{\dfrac{ 210}{7}}}[/tex]
[tex]\sf{\red{x = 30\: m}}[/tex]
Hence, The total length of the bamboo is 30m.

Answer:
y-intercept = (0, 8)
x-intercepts = (4, 0) and (-2, 0)
vertex = (1, 9)
5th point = (2, 8)
Step-by-step explanation:
As the coefficient of x² is negative, the curve will be "n" shaped.
y-intercept
crosses the y-axis when x = 0
substitute x = 0 into the function and solve for y:
[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]
Therefore, y-intercept = (0, 8)
x-intercept
crosses the x-axis when y = 0
set the function to zero and solve for x:
[tex]\implies -x^2+2x+8=0[/tex]
[tex]\implies x^2-2x-8=0[/tex]
[tex]\implies (x-4)(x+2)=0[/tex]
[tex]\implies x=4, x=-2[/tex]
Therefore, x-intercepts = (4, 0) and (-2, 0)
vertex
vertex form: [tex]y=a(x-h)^2 +k[/tex], where (h, k) is the vertex
expand vertex equation: [tex]y=ax^2 -2ahx+ah^2 +k[/tex]
compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]
[tex]\implies a=-1, h=1, k=9[/tex]
So vertex = (1, 9)
5th plot point
You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8
[tex]\implies -x^2+2x+8=8[/tex]
[tex]\implies -x^2+2x=0[/tex]
[tex]\implies x^2-2x=0[/tex]
[tex]\implies x(x-2)=0[/tex]
[tex]\implies x=0, x=2[/tex]
5th point = (2, 8)

a man brought 10 bags for Rs 5000. He sold 7 bags at Rs 550 wash and remaining at the rate of cost price.Find his profit percent
Answer:
7%
Explanation:
cost of 10 bag is rs 5000.
then cost of one bag is 500.
he sold 7 bag for rs550 each then total =550×7
= 3850
again, he sold rest 3bag at cost price =500 ×3
=1500
then ,. profit percentage; s.p- c.p/5000×100
350/5000×100
= 7%

Kathy saves $1 on the first day, $2 on the second day, $3 on the third day and so
on, saving an extra $1 on each subsequent day. On which day will she have over
$100 in total?
Answer:
3 moths and 10 days
Step-by-step explanation:
on each day she gets 1$ that means
1 month = 30 days
e.g. 3 6 9 30 60 90
means 90 days if we add also 1 month it will be 120 days
so 90 + 10 = 100
thats why 3 months and 10 day :)

Jaime has $2. 60 in dimes and nickels. The number of dimes is 14 more than the number of nickels. How many of each coin does he have?.
Dime is one-tenth of a dollar, while nickle is one-twentieth part of a dollar. Jaime has got 22 dimes and 4 nickle coin in this case.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case, since number of dimes is given in terms of number of nickels, so lets assume that:
Number of nickle Jaime got = [tex]x[/tex]Number of dime Jaime got = 14 more than the number of nickle = [tex]14 +x[/tex]Since 1 nickle's cost = $0.05,
thus, x nickles' cost = [tex]x \times 0.05[/tex] (in dollars)
And as 1 dime's cost = $0.10,
thus, 14 + x dimes' cost = [tex]0.10 \times (14 + x)[/tex] (in dollars)
Total amount Jamie have = Amount by nickles + Amount by dimes
Total amount Jamie have = [tex]0.10(14+x) + 0.05x[/tex] (in dollars) = $2.60 (as given in the problem)
Thus, we get:
[tex]0.10 (14+x) + 0.05x = 2.60\\1.4 + 0.10x + 0.05x = 2.60\\\\\text{Subtracting 1.4 from both the sides}\\\\0.15x = 1.2\\\text{Dividing both the sides by 0.15}\\\\\dfrac{0.15x}{0.15} = \dfrac{1.2}{0.15}\\\\x = 8\\[/tex]
Thus, Jamie got x = 8 nickles.
And number of dimes he got = x + 14 = 8 + 14 = 22
Thus, Jaime has got 22 dimes and 4 nickle coin in this case.

Maggie is buying 2 shirts that cost $8. 50 each. There is a 6. 5% sales tax. What is the total Maggie will pay for the shirts? Enter your answer in the box.
The total cost of the two shirt Maggie will pay after including the sales tax is $18.105.
What is cost price per ounce?The cost price per unit is the amount of money required to buy one unit of a brand or goods.
To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.
The cost of one shirt bought by the Maggie is $8. 50 each. Thus, the cost of the 2 shirts is,
[tex]C=2\times8.50\\C=17[/tex]
Thus, the total cost of the two shirts is $17.
Now, there is a 6. 5% sales tax on the selling price. Thus, the cost of the 2 shirts after the sales tax is,
[tex]C=17+17\dfrac{6.5}{100}\\C=17+1.105\\C=18.105[/tex]
Hence, the total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

PLEASE HELP ME: the ratio of cars to trucks on a highway at any given time is 12 to 8. If there are always more than 105 cars on the highway, what is the minimum number of cars that can be on the highway?
Answer:
70
Step-by-step explanation:
First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.
Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.
