18 is 40% of all
all=x
percent means parts out of 100
40%=40/100=4/10=2/5
18 is 2/5 of all
18=2/5 of x
'of' means multiply
18=2/5 times x
18=2x/5
multiply both sides by 5
90=2x
divide both sides y 2
45=x
there were 45 apples in the stand

First we need to found out how many pounds and luggage to small plane can carry, now that we know there is 490 pounds of mail.
1050 - 490 = 560
Now we need to find out the maximum number of passengers that can board the plane.
70p = 1050
We know that there are 560 avalible pounds left on the plane
70 x 8 = 560
560 + 490 = 1050.
Well if we go back to the question it says less than 1050. This means that 8 passengers times 70 pounds each would not be correct because the small airplane can carry less than 1050 pounds.
70 x 7 = 490
490 + 490 = 980
980 is less than 1050
So the answer would be 7 passengers.
7 Passengers is the maximum amount of passengers that can be taken.
I hope this helps!
Answer : h = 10.5$
Explanation: since it says the total amount is 30$ then
The equation should all add up to 30$
And with the h= 10.5$
When we plug h in the equation we get:
30 = 15 + 2(10.5-3)
30 = 15 + 2(7.5)
30 = 15 + 15
30 = 30
The line of best fit is used to illustrate a linear regression.
The value of pi based on the equation for the best-fit line is 3.0017
<h3>How to determine the value of pi</h3>
The equation of the line of best fit is given as:
Where:
- C represents the circumference
- D represents the diameter
The circumference of a circle is calculated as:
Where k represents a constant.
By comparison, we have:
Cancel out D
Hence, the value of pi is 3.0017
