Answer:
D(t) = 485t + 940
Step-by-step explanation:
D(t) = ?
We are told that the flight itself is 940 miles. This is a constant value, it will not change.
D(t) = ? + 940
Following this, we are also told the plane travels at 485 miles per hour. MPH usually indicates multiplication. 485 miles <em>per</em> each of hour (time here is represented by the variable t). 485t
D(t) = 485t + 940

Answer:
3 3/16
Step-by-step explanation:
Conversion a mixed number 8 1/2
 to a improper fraction: 8 1/2=8×2+1/2=16+1/2=17/2
To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2×3/3= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Divide: 17/2×8/3=17/2×3/8=17×3/2×8= 51/
16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/3 is 3/8) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen halves divided by eight thirds = fifty-one sixteenths.
51/16

Answer:
c. 59.3 ft²
Step-by-step explanation:
½× [(3.14×5²) + (10×4)]
= ½ × (78.5+40)
= ½× 118.5
= 59.3
