Answer:
D. 160
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
In this question:
For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:
3 white - 8 total
60 white - x total
So
Dividing both sides by 3
The correct answer is given by option D.
Answer: y = 2/3x + 3
Step-by-step explanation:
We will write the equation in slope intercept form (y=mx+b).
In the formula y=mx + b, m is the slope and b is the y intercept. We need the slope and y intercept numbers to write the equation. Since we know the slope we will use the given point to find the y intercept by plotting in the x and y coordinates into the formula.
1 = 2/3(-3) + b Solve for b
1= -6/3 + b
1 = -2 + b
+2 +2
b = 3
The equation will be y = 2/3x + 3
Since you know it's a square, you also know that all the sides are 3 2/3. So to find area you multiply, so 3 2/3 x 3 2/3. An easy way to do this is convert it to a mixed number (11/3) and then multiply:
11/3 x 11/3 = 121/9
