Find the area of a cement walkway of width 2 meters around a 50 m by 25 m pool.
9514 1404 393
Answer:
316 m²
Step-by-step explanation:
The centerline length of the walkway is 2×(52 m +27 m) = 158 m.
The area is the product of the walkway's centerline length and its width:
A = (158 m)(2 m) = 316 m²
_____
More detail on this approach
The centerlines of the long-side walkways are 25 m + 1 m + 1 m = 27 m apart. The centerlines of the short-side walkways are 50 m + 1 m + 1 m = 52 m apart.
The total length of the centerline is the perimeter of a 27 m by 52 m rectangle:
P = 2(L+W) = 2(52 m +27 m) = 158 m
_____
Usual approach
The area with the walkways is 54 m by 29 m = 1566 m². The area without the walkways is 50 m by 25 m = 1250 m². The difference is the area of the walkway, 1566 -1250 = 316 square meters.
(b)Newton has bought 12 dozen copies in Rs 4320. His expenditure to bring the copies
to his shop is Rs. 288. How much profit does he make in one copy after selling all
copies in Rs. 5760? Also how much profit in percent did he get in the business of
copy? Find it.
Plz answer
Answer:
He made a profit of 40-32 = Rs 8 per copy.
He got a 25% profit in the business of copies
Step-by-step explanation:
Newton buys and sells copies in his business. He bought 12 dozen = 12*12=144 copies in Rs 4320.
He also has Rs 288 in expenses to bring the copies to his shop, thus the total cost is 4320+288=4608.
Each copy finally cost 4608/144 = Rs 32.
He sold all copies for Rs 5760, at 5760/144= Rs 40 each.
Therefore, he made a profit of 40-32 = Rs 8 per copy.
The total profit in his business of copies was 5760 - 4608= 1152
This is a percentage of:
[tex]\frac{1152}{4608}*100 = 25\%[/tex]

Hello can anyone help me with this ? Thank you ill mark brainless
Answer:
[tex]\huge\boxed{n=5m}[/tex]
[tex]\huge\boxed{55 \ \text{novels}}[/tex]
Step-by-step explanation:
With this word problem, we can model it into an equation which we can interpret to find values.
If we need to read 5 novels per month and n represents the amount of novels read in m months, we know that n will be the dependent variable (y) as it's a direct function of the number of months. This makes m the independent variable (x).
Since there are 5 novels a month, the equation will be 5 times the number of months equals the number of novels per month.
aka - [tex]n=5m[/tex]
We can now substitute inside the equation with 11 months as m, and find the value of n.
[tex]n = 5 \cdot 11[/tex] [tex]n=55[/tex]Hope this helped!
Answer:
The answer is 55
Step-by-step explanation:
Because for every 1 month he reads 5 books
if you do 5 times 11 you get 55
and to check your answer you divide 55 by 5 you get 11
so your equation would be 5 times 11
and your answer would be 55.
hope this helps ;)
Which is an equation of a direct proportion?
Answer:
y=-3x
Step-by-step explanation:
The meaning of direct proportion is that the ratio remains the same, and the ratio will only remain the same if y= a constant number into x

Answer:
y = 4x -1
I think this is correct
Answer:
y=4x-1
Step-by-step explanation:
What we are doing here is isolating the y variable, and/or solving for y in terms of x. We add y to both sides then subtract 1 from both sides to get y=4x-1. Also, this problem is worded incorrectly and should be worded as 'solve for y in terms of x,' or 'isolate y.'

Answer:

Step-by-step explanation:
13. t plus the product of three and t
Answer:
4t
Step-by-step explanation:
Let's form an equation here just to put it visually.
So it would be t+3*t
We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)
Now we can do t+3t which is 4t
If this doesn't make sense, then you can look at it this way
You do 1t+3t and since they're like terms, you can combine them and do 4t.

Answer:
Answer:
2)Ben Bean's Drinks
1) 4 variables, of which 1 is categorical
Step-by-step explanation:
Popular Drinks at Ben's Beans Coffee Shop
Drink Type Calories Sugars (g) Caffeine (mg)
Brewed coffee Hot 4 0 260
Caffè latte Hot 100 14 75
Caffè mocha Hot 170 27 95
Cappuccino Hot 60 8 75
Iced brewed coffee Cold 60 15 120
Chai latte Hot 120 25 60
The individuals in this data set are:
1) Ben Bean's customers
2) Ben Bean's drinks
3) Caffeine Contents
This is a list of the coffee drinks not customers so option 2 is correct. Nor it deals with caffeine content.
The data set contains
1) 4 variables, of which 1 is categorical
2) 4 variables , of which 2 are categorical
3) 6 variables , of which 1 are categorical
4) 6 variables , of which 2 are categorical
Here option1 is correct because we have 4 variables ( type, calories, sugar, caffeine)out of which 1 ( type) is divided into 2 categories (hot or cold).
Factor the expression 5x + 10
Answer:
5(x+2)
Step-by-step explanation:
When factoring, always use the greatest common factor (GCF) method first. 5x and 10 have a GCF of 5, so this is applicable. Divide each factor by 5:
(5x)/5=x
10/5=2
Now, factor 5 out of 5x+10:
5(x+2)
An episode of the television show, Legend of the Far Mountain, normally lasts 30 minutes and has 8 minutes of commercials. Tonight is the season finale, and the show will be 90 minutes long.
If the ratio of the show's length to the amount of commercial time is the same, how many minutes of commercials there will be during tonight's show?
Answer:
24
Step-by-step explanation:
If there will be 8 for 30
and it's 90 it mean it's just has more 30's
30 + 30+ 30=90
Help pleaseeeee?????
Answer:
A. 4x-10
Step-by-step explanation:
We see that this is a rectangle. To find the perimeter, we do L+W+L+W. So in this case, we can do (x+2)+(x-7)+(x+2)+(x-7). We can also simplify this to 2(x+2)+2(x-7)
Combine like terms now.
Simplify this to:
2x+4+2x-14
Simplify further:
4x-10
Answer:
4x-10
Step-by-step explanation:
The perimeter is the total around a shape. That means there will be two copies of each equation.
2(x+2)= 2x+4
2(x-7)= 2x-14
Add the two equations together and simplify.
2x+4+2x-14=
Add the like terms 2x together.
2x+2x= 4x
Keep doing the problem
4x+4-14
Solve 4-14 which equals -10

Are there concepts/processes to strictly follow in writing radicals as expressions with rational exponents?
Answer:
The concept or process is [tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex].
Step-by-step explanation:
Consider the provided information.
The following property can be used to rewrite each radical as an exponent.
The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.
[tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex]
For example:
[tex](27)^{\frac{2}{3}}=(\sqrt[3]{27})^2[/tex]
[tex](27)^{\frac{2}{3}}=(3)^2[/tex]
[tex](27)^{\frac{2}{3}}=9[/tex]
Hence, the concept or process is [tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex].

Answer:
Step-by-step explanation:
25 feet per minute
in 10 minutes
25ft*10=250ft
the diver is 250+200=450
the diver was at 450 below the sea level
Answer:
450 feet below sea level
Step-by-step explanation:
So:
We are looking at 10 minutes ago. If he is being pulled up, that means before he was even more down.
Therefore 25 feet is 1 minute so 10 minutes is 250 feet.
As he was more down below sea level you add 200 feet below sea level with 250 feet below sea level.
This will give you 450 feet below sea level.
I hope this helps!

At a particular restaurant, each mini hotdog has 100 calories and each slider has 200 calories. A combination meal with mini hotdogs and sliders is shown to have 1200 total calories and 4 times as many mini hotdogs as there are sliders.
Answer:
There would be 2 sliders and 8 hotdogs.
Step-by-step explanation:
1 slider= 200 cal
2 sliders= 400 cal
2x4= 8
1 mini hotdog= 100 cal
8 mini hotdogs= 800 cal
800 cal + 400 cal = 1200 cal
