Answer:
D
A right triangle is a triangle that has one 90 degree angle, so looking at the options i would say D
Step-by-step explanation:
First find the amount of the difference between the original price and the current price:
$10,600 - $7,400 = $3,200
Divide the difference by the original price:
3200 / 7400 = 0.4324 = 43.2% increase.
X^2 + 4x = 0
x^2 + 4x + 4 = 0 + 4
(x + 2)^2 = 4
The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following:
X = no of tetra fish
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.
X = 2Y.
Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.
