Answer:
The answer to your question is 6 organisms.
Step-by-step explanation:
Data
625 ft² -------- 1 multicellular organism
3750 ft² -- number of organisms
Process
1.- To know the number of organisms that can supply 3750 ft² of lawn, we need to use proportions and cross multiplication.
625 ft² ------------------ 1 multicellular organisms
3750 ft² ------------------ x
x = (3750 x 1) / 625
x = 3750 / 625
x = 6
2.- Conclusion
3750 ft² can supply of oxygen 6 organisms.
Answer:
The answer is B.It is one-half the area of a square of side length 4 units.
Step-by-step explanation:
Given a coordinate grid shown with triangle of measurements with base 4 units and height also 4 units.
We have to find the area of triangle which can be calculated as
⇒
=
we have to choose the statement describes the area of the triangle evaluate above.
Option A: Not matched ∵equals to [area of rectangle of length 4 units width 2 units]=
Option B: matched : given one-half the area of a square of side length 4 units.
⇒
Option C : Not matched : It is twice the area of a rectangle of length 4 units and width 2 units
⇒
Option 4 : Not matched : It is twice the area of a square of side length 4 units.
⇒
So, the correct option is B. It is one-half the area of a square of side length 4 units.
Let's rewrite the equation with x and y on the left side of the equal sign.
5x-4y=8 --------(1)
3x-3y=3---------(2)
Divide equation (2) by 3,
x - y= 1
now we have,
5x-4y = 8 --------(1)
x - y = 1 ---------(2)
To eliminate x, multiply equation (2) by 5. This makes both the coefficients of x to be 5. Subtract the second equation from the first equation.
5x - 4y = 8
(2) * 5 5x - 5y = 5
(-) (+) (-)
----------------
0x +y =3
Therefore, y=3
Substitute the value of y, in any one of the two equations. Let's substitute y in the second equation.
x-3=1
x=4
x=4 and y=3
