There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

Word problem: If 1 yard equals 3 inches, how many inches are in 18 yards?

Mariulka [41]

Answer:

54 inches

Explanation:

From the question, we have that:

1 yard = 3 inches

We are to find the equivalent value of 18 yards in inches. This can be expressed as:

18 yards = x

where x is the unknown value.

Get the value of x by dividing both equations:

$\frac{1}{18}=\frac{3}{x}$

Cross multiply

$\begin{gathered} 1\times x=3\times18 \\ \\ x=54 \end{gathered}$

This shows that there are 54 inches in 18 yards
