15. The floor plan of the basement of a shopping centre is drawn to a scale of 1:400.
If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)
Answer:
4 hectaresStep-by-step explanation:
The scale factor is:
k = 1/400Applied to the area we consider k² as the area is the product of two dimensions.
Find the actual area:
0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectaresPLS HELP NOW I DONT UNDERSTAND

The diameter of a circle is 14 centimeters. What is the circle's area?
Answer:
49π or 153.94 to 2dp
Step-by-step explanation:
diameter=14
radius=7
equation for area= r^2 × π
7^2=49
49×π=49π
49π=153.93804002589
or 153.94 to 2dp
Answer:
153.93804003
Step-by-step explanation:
The area of a circle is: A= πr²
So we have to divide the diameter by 2 which is 7 and that will give us our radius
A= π(7)²
A= π(49)
A=153.93

Answer:
Step-by-step explanation:
a = \(\sqrt{12^2 -9^2} = \sqrt{144-81} = \sqrt{63}\)
We use the minus because we are searching a leg.
A leg is always shorter than the hypotenuse
Answer:
a = 7.9 or a = √63
Step-by-step explanation:
a² + b² = c²
(The two shorter sides of a triangle are always a and b while the longer side will always be c)
So, here the longer side of this triangle is 12 and the shorter sides are 9 and a (unknown).
The equation is: a² + 9² = 12²
But to find the value of a, the formula will be 12² - 9² = a²
12² - 9² = a²
144 - 81 = a²
63 = a²
the square root of 63 = 7.9 so that means a = 7.9

9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
You have a pizza with diameter 12
2
3 in., and a square box that is 12.65 in. across. Write 12
2
3 as a decimal. Can you fit the pizza inside the box?
What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Step-by-step explanation:
Evander would like to buy a new hockey stick. He earns $15 time he cuts the grass in his neighborhood. Because of his busy schedule, he can cut grass on Saturdays and Sundays. Evander is responsible for paying $10/week toward his cell phone bill. He also enjoys chocolate and has a $2 bar least twice weekly. Every time he cuts two lawns, he has to fill up the lawnmower with $5 worth of gas.
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
When could Evander save enough for the stick if he stopped eating chocolate bars?
When could Evander save enough for the stick if he was able to cut another lawn on Wednesday nights AND stopped eating chocolate?
Answer/Step-by-step explanation:
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
earns - 30 pays - $10pb $2b $5(this is for the 2 days)
SO he gets 30 but spends 19,
Meaning he gets $11 proffit.
30-19 = $11
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
He makes $11 every week. so 229.99/11 = 20.9, so it will take him 21 weeks to get it.
When could Evander save enough for the stick if he stopped eating chocolate bars?
Ok so he would be getting 2 dollars more so that would make it $13. So 229.99/13 = 17.69, meaning it will take 18 weeks to get it.
