The equation representing the given statement is ~
The least number of lawns that he can cut and buy the computer is 10 lawns ~
Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
- total number of lawns cut × $50
total savings is equal to ~
hence,
by solving for " x (number of lawns cut) " we get ~
Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is
Answer:
1636 cm^2
Step-by-step explanation:
cut in itwo two shapes a rectangle and isosceles trapizoid
Area - 1/2 hight(base x length)
1/2 x 14(6x17) = 714 cm^2
Area of rectangle- 2(wl x hl x hw) = 922 cm^2
l = 17
w = 13
h = 8
add the areas - 922 + 714 = 1636 cm^2
The water should fill the aquarium to 1.5 feet
Solution:
Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.
This means volume of aquarium is 9 cubic feet
Given that aquarium is 2 feet wide and 3 feet long
To find: Height of aquarium
Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula
<em><u>The volume of cuboid is given as:</u></em>
volume of cuboid = 
Where "l" is the length
w is the width
"h" is the height
Substituting the values, we get,
Thus the height of aquarium is 1.5 feet
Answer:
13 chairs in each row
Step-by-step explanation:
divide 65 by 5 to get 13
The most important thing in this problem is understanding and then dividing the given units properly. The first thing that is given is that the CD makes 58 1/2 revolutions in 3/4 minutes. We have to first simplify the number of revolutions made by the CD. This will make the problem in hand very easy.
Number of revolutions made by the CD = 58 1/2
= 117/2
Then
The unit rate = (117/2)/(3/4)
= (117 * 4)/(2 * 3)
= (117 * 2)/3
= 39 * 2
78
So the unit rate is 78 revolutions per minute.
