A map is drawn to a scale of 1 : 240 000.
(i) If a seawater lake has an area of 3.8 cm² on the map, find its actual area in square kilometres.
(ii) If the actual area of a plot of land is 2 908 800 m², calculate its area on the map.
Step-by-step explanation:
Above are the explanations
A map is drawn on a scale of 1: 240 000.
(i) Actual area [tex]$=21.888 \mathrm{~km}^{2}$[/tex]
(ii) Area on the map = [tex]$0.505 \mathrm{~cm}^{2}$[/tex].
How to estimate the area on the map?(i) 1 cm: 240000 cm = 1 cm: 2.4km
Area scale [tex]$=1^{2} \mathrm{~cm}^{2}: 2.4^{2} \mathrm{~km}^{2}$[/tex]
[tex]$=1 \mathrm{cm}^{2}: 5.76 \mathrm{~km}^{2}$[/tex]
[tex]$1 \mathrm{~cm}^{2}: 5.76 \mathrm{~km}^{2}$[/tex]
[tex]$3.8 \mathrm{~cm}^{2}: 21.888 \mathrm{~km}^{2}$[/tex]
Actual area [tex]$=21.888 \mathrm{~km}^{2}$[/tex]
[tex]$=21.9 \mathrm{~km}^{2}[/tex]
(ii) 1 cm: 240000 cm = 1 cm: 2400 m
Area scale [tex]$=1^{2} \mathrm{~cm}^{2}: 2400^{2} \mathrm{~m}^{2}$[/tex]
[tex]$=1 \mathrm{~cm}^{2}: 5760000 \mathrm{~m}^{2}$[/tex]
[tex]$1cm}^{2}: 5760000 \mathrm{~m}^{2}$[/tex]
[tex]$0.505 \mathrm{~cm}^{2} ; 2108800 \mathrm{~m}^{2}$[/tex]
The area on the map = [tex]$0.505 \mathrm{~cm}^{2}$[/tex].

Answer:
I believe the answer to your question is 38.
Step-by-step explanation:
Here is what I did: First, I found the radius, and to do that, I did 12 divided by 2, which gave me 6. then I did 6 divided by 2, to find the radius, of the radius I just found. which gave me 3, then I did 3 times 12, which gave me 36, so the answer should be 38 :)

Percentage with sprinkles = sprinkles / total
= 14/35
=.4
= 40 %
Answer:
40%
Step-by-step explanation:
14 + 21 = 35
14/35 × 100 = 40

The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons. What was the total paper waste generated over these two years in the region, expressed in scientific notation?
91.8 ⋅ 107 tons
91.8 ⋅ 1014 tons
9.18 ⋅ 1014 tons
9.18 ⋅ 107 tons
Answer: [tex]9.18 x 10[/tex]⁷[tex]tons[/tex]
Step-by-step explanation:
Given: The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons.
Then, the total paper waste generated over these two years in the region :-
[tex]41,300,000 + 50,500,000 = 91,800,000[/tex]
In scientific notation,
[tex]91,800,800 = 9.18 x 10[/tex]⁷
Hence, the total paper waste generated over these two years in the region =

Answer:
-25 feet
Step-by-step explanation:
We know that the change in altitude for the air balloon is -1500 feet, all within a span of 60 minutes, which then we are asked what is the rate of change.
To find the rate of change, we have to be able to divide a number by both sides that will not give us a decimal or very odd number. To avoid getting a decimal, divide both sides by 60.
-1500/60 = -25
60/60 = 1
So the rate of change would be -25 feet
A textbook is 14/15 inch thick. How many
textbooks can be stacked on a shelf that is
56 inches high?
Answer:
60 textbooks
Step-by-step explanation:
1) 56*15:14=60
Answer:
60 textbooks
Step-by-step explanation:
To get the answer, you have to divide 56 by 14/15. What I'd do is id think of 56
as 56/1. I'd change 14/15 into a multiplicative inverse/reciprocal, ending up with 15/14. From there, id multiply 56/1 and 15/14, ending up with 840/14.Using long division, id do 840 divided by 14, ending up with 60.

Answer:
Water (cups): 14, 28, 42, 56, 70
Lemon Juice (cups): 2, 4, 6, 8, 10
Divide the number of cups of water by 7 to find the number of cups of lemon juice.
Answer:
See photo
Step-by-step explanation:
Completing the rule:
With the water, you add 14 each time. They started at 14 and added another 14 to get 28. Then you add 14 to 28 and get 42, and so on.
with the lemon juice, it’s very similar except you’re adding 2 each time. They started at 2 and added another 2 to get 4. Then you add 2 and get 6, and so on.
The final question:
This last blank is asking what number you divide the water by to get the lemon juice. If we use fact families, you can take the 14 (from water) and divide it by 2 (from lemon juice) to find that 7 is you missing number. You’ll then be able to plug 7 in to the following numbers. 28 divided by 4 is 7, 42 divided by 7 is 6, etc.

A bouquet of flowers contains D daisies and T tulips and contains a total of F flowers. The number of daisies is two more than the number of tulips. Which equation matches this scenario?
A. D+2T=F
B. F−D+2=T
C. 2D+T=F
D. D+T+2=F
E. D+T=F+2
Answer: B (F-D+2=T)
Step-by-step explanation:
We know that daisies has 2 more than the tulips. (D+2 = T)
The answer is B
Flowers - Daises + 2 = T
Since daises has 2 more flowers than tulips, thats why theres a (+2)

Answer:
a(n)= 120(1/2)^(n-1)
Step-by-step explanation:
60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2
a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)
Answer:120(1/2)^(n-1)
Step-by-step explanation:
60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2
a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)

Option B: [tex]5x^{5} +C[/tex]
Option C:[tex]5x^{5}[/tex]
Option D: [tex]x^{5} + C[/tex]
Answer:
[tex] \displaystyle D) {x}^{5} + \rm C[/tex]
Step-by-step explanation:
we would like to integrate the following Integral:
[tex] \displaystyle \int 5 {x}^{4} \, dx [/tex]
well, to get the constant we can consider the following Integration rule:
[tex] \displaystyle \int c{x} ^{n} \, dx = c\int {x}^{n} \, dx[/tex]
therefore,
[tex] \displaystyle 5\int {x}^{4} \, dx [/tex]
recall exponent integration rule:
[tex] \displaystyle \int {x} ^{n} \, dx = \frac{ {x}^{n + 1} }{n + 1} [/tex]
so let,
[tex]n = 4[/tex]Thus integrate:
[tex] \displaystyle = 5\left( \frac{ {x}^{4+ 1} }{4 + 1} \right)[/tex]
simplify addition:
[tex] \displaystyle = 5\left( \frac{ {x}^{5} }{5} \right)[/tex]
reduce fraction:
[tex] \displaystyle = {x}^{5} [/tex]
finally we of course have to add the constant of integration:
[tex] \displaystyle \boxed{ {x}^{5} + \rm C}[/tex]
hence,
our answer is D)

PLEASE HELP ME SOLVE THESE!
-3n-4n-17=25
-15+7.5(2d-1)=7.5
Please show me how as well please :)
Answer:
-3n-4n = 25 + 17
-7n = 42
n= -6
the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.
-15 + 15d -7.5d =7.5
15d - 7.5d = 7.5 + 15
7.5d = 22.5
d = 3
for the part where theres 7.5(2d-1)
you multiply each number inside the bracket by 7.5, its called distributivity of multiplication
hope that answers your question
hope you understand what i wrote lol
good luck:)
Answer:
Question 1
Original Equation:
-3n-4n-17=25
Add 17 to both sides (cancels out the -17)
-3n-4n=42
Combine -3n and -4n.
-7n=42
Divide by -7
n = -6
Question 2
Original Equation:
-15+7.5(2d-1)=7.5
Distribute:
-15+15d-7.5=7.5
Add 7.5 to both sides:
-15+15d=15
Add 15 to both sides:
15d=30
Divide by 15:
d = 2
Let me know if this helps!
