Answer:
He can feed 200 plants
Step-by-step explanation:
To solve this, we will follow the step below:
first, convert 25 g to kg
25 g = 25/1000 = 0.025 kg
Now using proportion to solve;
Let x be the number of food plant he can feed the plant
0.025 kg = 1
5 kg = x
cross-multiply
0.025×x = 5×1
0.025x =5
Divide both-side of the equation by 0.025
0.025x/0.025 = 5/0.025
x=200 plants
Therefore, he can feed 200 plants
The third angle is obtuse.
Since the shape has 3 sides, then the total measure of degrees is (n-2)180 = (3-2)180 = 180°.
So our equation would be
180° = 35° + 30° + x°
x = 115°
115 is greater than 90, so the angle is obtuse.
Answer: Bottom left corner
Let n be an odd number. Because 4n is a multiple of 2, it is an even number.
============================================
Explanation:
The square has a side length of n, so its perimeter is 4n since n+n+n+n = 4n.
We can rewrite 4n as 2*2n = 2m where m = 2n is an integer. Any number in the form 2*(some integer) is always even. Even numbers always have 2 as a factor.
So whenever it comes to proving something is even, the ultimate goal is to get it into the form 2*(some integer). If we can do this, then the number is even. If not, then the number is odd.
Answer:
D
Step-by-step explanation:
f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15) Remove the brackets
f(x) - g(x) = -9x^2 - 7x + 12 - 3x^2 + 4x + 15
f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15
f(x) - g(x) = -12x^2- 3x + 27
