40/5=8
The pitcher allowed 8 runs in 40 innings.
Answer:
2/8
Step-by-step explanation:
To find an equivalent of a fraction, multiply numerator and denominator by the same value:
1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8
Multiple factor product divisor and dividend
<h3>Write a model in simplified form for the total time t (in hours) of the trip:</h3>

<h3>It takes 2.95 hours when r is 4 miles per hour</h3>
<em><u>Solution</u></em>:
Given that,
<h3>You travel 3 miles downstream in a kayak at a speed of r miles per hour</h3>
Downstream:
Speed = r miles per hour
Distance = 3 miles
Time taken is given as:

<h3>You turn around and travel 4 miles upstream at a speed of 0.5r miles per hour</h3>
Upstream:
Speed = 0.5r miles per hour
Distance = 4 miles
Therefore,

<h3>Finally, you turn around and return to your original starting point at a speed of r + 1 miles per hour</h3>
Therefore,

<em><u>a)Write a model in simplified form for the total time t (in hours) of the trip</u></em>
The total time taken is:
eqn 1 + eqn 2 + eqn 3

<em><u>b)How long does your trip take when r is 4 miles per hour?</u></em>
Substitute r = 4

Thus it takes 2.95 hours when r is 4 miles per hour
Answer: B
For a number to be in correct scientific notation, the first number or the decimal number has to be less than 10. In this case, 75.3 is not less than 10, hence it is the incorrect answer.
