Answer:
39/60 is a rational number halfway b/w the given numbers.
Step-by-step explanation:
Add both of these numbers and then divide the result by 2.
(1/3+3/10)/2
=((30+9)/30)/2
=(39/30)*1/2
=39/60
Answer:
d
Step-by-step explanation:
2(7)+6=20
14+6=20
20=20
Answer:
4 - 5 = 40 books about travel. 80 are school stories.
6-7 = 30 are about nature. 48
8 =24
9 = 18
10 = 2001
Step-by-step explanation:
<h3>4,5,6,7,8</h3>
1/10 = 24 = sport
1/8 = 30 =nature
1/6= 40 =travel
1/5 = 48 = adventure
1/3 = 80 = schools stories
To get that you just have to read the question, find the fractions, percentages etc.
I put them all into fractions and divide 240 by the denominator.
<h3>9</h3>
For question 9, you just have to add all of the amounts of books together and take that away from the total amount. In this case it is 240 - 222 = 18
<h3>10</h3>
You just have to write it out.
ANSWER
EXPLANATION
The volume of a pyramid is given by the formula,
The base of the pyramid is an equilateral triangle.
The base area is
The volume of the pyramid is now equal to:
Let say the length of the rectangle is x. The material that can be used would determine the perimeter of the rectangle. Using the perimeter formula you can find the rectangle width
perimeter= 2(width+length)
400= 2(width + x)
200= width+x
width= 200-x
The function to determine the area would be:
area= length * width
area= x* (200-x)
area= 200x- x^2
To find the highest area you need to find out the vertex by finding the value of x when the differentiate of the function equal to zero.
dx/dy= 200- 2x = 0
2x= 200
x=100
If you put x=100 into the area function you will find
area= 200x- x^2
area= 200(100)- (100)^2
area= 20,000 - 10,000= 10000 feet^2
