When it says "how much more", it means to find the difference between the siblings' growth by subtracting their growths.

Step 1: Convert both mixed numbers to improper fractions

$3\frac{1}{3}- 1\frac{2}{3}$ Learn how to do that here: brainly.com/question/13099965

$3\frac{1}{3}\\\\3\times3=9\\9+1=10\\\\\frac{10}{3}$

$1\frac{2}{3}\\\\3\times 1 = 3\\3 + 2 = 5\\\\\frac{5}{3}$

$\frac{10}{3} - \frac{5}{3}$

Step 2: Subtract

10 - 5 = 5

$\frac{5}{3}$ or $\bold {1\frac{2}{3}}$

Therefore, Robert grew $\bold {1\frac{2}{3}}$ more than his brother.

Given a quadratic with one zero at 3 and a vertex at (-1,4), what is the other zero?

s2008m [1.1K]

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form".

Game wardens use experiments to help determine the number of wild horses in a national park. Suppose 40 wild horses are caught,

Lana71 [14]

I think the answer is 136 wild horses because they caught 40 the first time then they caught 100 the second time but four had already been caught so 100 + 40 = 140 - 4 = 136

The sum of three consecutive odd numbers is one hundred fifty-nine

xeze [42]

First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.
