Harold walks 3/4 mile in each 5/6 hour. Calculate Harold's unit rate. Explain how you found your answer.

Answers

Answer 1
Answer: To solve this problem, you must apply the proccedure shown below:

 1. The problem gives the following information: Harold walks 3/4 miles in each 5/6 hours. Therefore, you have to divide  3/4 miles by 5/6 hours, as below:

 unit rate=(3/4)(5/6)
 unit rate=(3x6)(4x5)
 unit rate=18/20 

 3. When you simplify, you obtain:

 unit rate=9/10

 4. Therefore, as you can see, the answer is: Harold's unit rate is 9/10.

Please Help!Three years ago, Jolene bought $875 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of
6 1/2%

per year. How much is the stock worth now? Round the answer to the nearest cent.

The stock is worth $_______now.

Answers

If you would like to know how much is the stock worth now, you can calculate this using the following steps:

1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057

The correct result would be: The stock is worth $1057 now.

What is 9.33 in fraction form

Answers

Answer:
= 933/100

= 933/100

= 9  33/100 
Work:
Write the decimal number as a fraction
(over 1)
9.33 = 9.33 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator (N)
N = 9.33 × 10 × 10 = 933
Denominator (D)
D = 1 × 10 × 10 = 100

N / D = 933 / 100

Simplifying our fraction

= 933/100

= 933/100

= 9  33/100

A plane at an altitude of 20000 feet starts to descend for landing after flying for six hours. The entire flight time was 6 hours 40 minutes. Determine the average rate of descent of the plane

Answers

Check the picture below.

so, let's see, the plane departs from (0, 0), the origin, goes up to 20000 feet, sticks around flying for 6 hours, 6hrs = 3600 minutes, (6*60).

so the plane's descent starts off at the point (3600, 20000) down to (3640, 0) as you see in the picture, keeping in mind that average rate of change = slope.

\bf (\stackrel{x_1}{3600}~,~\stackrel{y_1}{20000})\qquad (\stackrel{x_2}{3640}~,~\stackrel{y_2}{0}) \n\n\n slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-20000}{3640-3600}\implies \cfrac{-20000}{40} \n\n\n \cfrac{-5000}{1}\cfrac{ft}{minute}\implies -5000(ft)/(min)

the slope is negative, since it's a descent, the plane is coming down, not going up over the minutes axis.

Answer: 500 feet per minute

Step-by-step explanation:

Landing time 40min with an altitude of 20000 remaining

40=20000 | both sides /40

1=500
