4th grade math question Joey walk 333 ft how many yards did Joey walk? At 5 yds vs 15 ft
icang [17]

111 yards

Explanation

Step 1

to solve this we need to know the equivalence

\begin{gathered} 3\text{ ft= 1 yd} \\ 3\text{ ft}\leftrightarrow1\text{ yd} \end{gathered}

Now, we can apply a rule of three

let x represents the number of yards in 333 ft, so

so

\begin{gathered} if \\ 3\text{ ft}\rightarrow\text{ 1 yd} \\ \text{then} \\ 33\text{ ft}\rightarrow x \end{gathered}

as the ratio is the same, we have a proportion

\begin{gathered} \frac{3\text{ ft}}{1\text{ yd}}=\frac{33\text{ ft}}{x\text{ yd}} \\ \frac{3}{1}=\frac{33}{x} \end{gathered}

Step 2

now, solve for x

\begin{gathered} \frac{3}{1}=\frac{333}{x} \\ \text{cross multiply} \\ 3\cdot x=333\cdot1 \\ 3x=333 \\ \text{divide both } \\ \frac{3x}{3}=\frac{333}{3} \\ x=111 \end{gathered}

so, the answer is 111 yards

I hope this helps you

Find the first four terms of each sequence. <br><br> F(n) = 3n - 1
timofeeve [1]

Answer:

2, 5, 8, 11

Step-by-step explanation:

F(n) = 3n - 1

put n=1

F(1) = 3(1) - 1 = 2

put n=2

F(2) = 3(2) - 1 = 6 - 1 = 5

put n=3

F(3) = 3(3) - 1 = 9 - 1 = 8

put n=4

F(4) = 3(4) - 1 = 12 - 1 = 11
