\bf \cfrac{bulls}{cows}\qquad \cfrac{18}{45}\implies \cfrac{2}{5}
\\\\\\
\textit{now lets add 4 to each}\qquad \cfrac{bulls}{cows}\qquad \cfrac{18+4}{45+4}\implies \cfrac{22}{49}

now, 22/49 is not simplifiable further, thus the ratio changed.

Solve by completing the square p^2 +10p - 3 = 0
Mrac [35]

Solving p^2 +10p - 3 = 0 by completing the square method we get (p+5)^2-28=0

Step-by-step explanation:

We need to solve by completing the square method.

We are given: p^2 +10p - 3 = 0

The Completing square method is: (a+b)^2 = a^2+2ab+b^2

Solving:

p^2 +10p - 3 = 0\\For \,\,making\,\,perfect\,\,square\,\,we\,\,add\,\,and\,\,subtract\,\,(5)^2\\p^2+2(p)(5)^2+(5)^2-3-(5)^2=0\\(p+5)^2-3-25=0\\(p+5)^2-28=0

Solving p^2 +10p - 3 = 0 by completing the square method we get (p+5)^2-28=0

Maxwell’s vegetarian tacos require 34 tablespoons of chili powder for every 12 pounds of vegetables. How much chili powder will
Crazy boy [7]

Answer:

2 1/4

How?

Set up a proportion. The proportion will be teaspoons of chili powder over pound of vegetables.

Because of the above, the first proportion will be:

x is 3/4 and y is 1/2. Across from that proportion make another one

x is "n" because you're trying to figure out how much chili powder you need. y is 1 3/4.

Multiply 3/4 and 1 3/4, which is 9/16. Then, divide 9/16 and 1/2, which is 9/8. Simplify it to 1 1/8, and Maxwell will need 1 1/8 teaspoons of chili powder.
