Since all sides are equal, it is an equilateral triangle. Therefore each angle equals 60°.
7x - 3 = 60
7x = 63
x = 9
1. Move 2/x to the left side of proportion by changing sign before it:
3/x - 1 - 2/x = 4
2. Move 1 to the right side of proportion and change it's sign as well:
3/x - 2/x = 4 + 1
3. Sum numerators in the left side of proportion since they have common denominator (x) abd also sum the numbers in the right side too:
(3-2)/x = 5
4. Calculate numerator in the left side of proportion:
1/x = 5
5. Move 1 to the right side of proportion by dividing that side by it:
x = 1/5
ANSWER
36 cubic inches.
EXPLANATION
The volume of a square pyramid is calculated using the formula:
where l² is the area of the base and h= 6 inches is the height of the square pyramid.
We substitute the values into the formula to get,
We simplify to get:
Therefore the volume of the square pyramid is 36 cubic inches.
Answer:
1412.188832
Step-by-step explanation:
Answer: 24
Step-by-step explanation:
36/3 = 12
This means that 12 is one third of the flower pots.
Since she uses two thirds, just multiply the answer by 2.
12x2 = 24, so 2/3 is 24
Therefore, Mary plants daisies in 24 flower pots.
Hope this helps!
