Answer:
Miguel and Grace have collected 7 coins each week.
Fraction of navy beans = 1 - 2/5 = 3/5. So there are 2/5 * 550 = 220 white bean and 3/5 * 550 = 330 navy beans
ratio of white beans to navy beans is 220 : 330 = 2 : 3
Answer is 2:3.
“Suppose the graph below is the complete graph of a function f. The Fundamental Graphing Principle for Functions says that for a point (a, b) to be on the graph, f(a) = b. ... The answer is that we don't need a formula for f(x), we just need the values of f(x). The values of f(x) are the y values on the graph of y = f(x).”
Answer:
106 degrees
Step-by-step explanation:
Sides AB and CD are equal in length and sides AD and BC are parallel to each other. This tells us that angles B and C are equivalent. Knowing this, we can set up the following equation to solve for x:
Subtract both sides by 42
Subtract both sides by 2x
Divide both sides by 2
Now, to find angle ABC, or angle B, we can plug x back into its expression:
Therefore, the measure of angle ABC is 106 degrees.
I hope this helps!
A = 1/2 h (b1+b2)
so
h = 2A / (b1+b2)
h = [2(3x^2 + 5x)] / (2x + 1 + <span>x + 4)
h = (6x^2 + 10x)/(3x +5)
h = 2x(3x + 5)/(3x +5)
h = 2x
