Important:  Please express fractions properly:  use the " / " symbol to represent division.  Your question should read:

"<span>A Mallard duck flies 5/6 of a mile in 1/60 of a hour.  Find the rate (speed) at which it flies."

To do this, divide the distance flown by the elapsed time:
                                    5
5/6   mile                  -----
-----------------   =  -------6------------- miles / hr
1/60   hour </span>
                                        1
                                       -----
                                         60

to divide 5/6 by 1/60,  write    5/6 and multiply that by the reciprocal of 1/60. 

In other words,   write    5/6, invert (1/60) and then multiply.

This comes out to                    (5)(60)
                                                ----------  mph
                                                  (6)(1)

Do not multiply here.  Instead, reduce 60/6 to 10/1.

Can you now write out the final answer, in mph?  (miles per hour)

7.1x10^-2 as an ordinary number
Sonja [21]
Hey there,

So let's start off with one part of this equation . . . 


10^{-2} would be 0.01.

So, we have 0.01 has our answer (so far).
 
Then we would do 7.1 × 0.01, this would give us  . . .

0.071.

Your correct and final answer would be \boxed{0.071}

Hope this helps you!

Orin solved an equation and justified his steps as shown in the table.
sergij07 [2.7K]

Answer:

Step-by-step explanation:

Given the equation as

\frac{3x}{5} -3=12

apply multiplication property of equality where you multiply every term by 5

\frac{3x}{5}*5 -3*5=12*5

3x-15=60------------------apply addition property of equality

3x-15+15=60+15

3x=75--------------------------appy division property of equality by dividing both sides by 3

3x/3=75/3

x=25

An object is moving at a speed of 95 kilometers every 7.5 weeks. Express this speed in
Aleksandr-060686 [28]

Answer:

<h2>5,936.76 feet/day</h2>

Step-by-step explanation:

Formula to use to get the speed is expressed as speed = Distance/Time

Given parameters

Distance = 94km

Time = 7.5weeks

Since we are to express the answer in feet per day, we will convert the distance to feet and time to days.

For the distance:

Given the conversion

1 km = 3280.84 feet

95km = (95*3280.84)feet

95km = 311,679.8 feet

For the time:

If 1 week = 7 days

7.5weeks = (7.5 * 7)

7.5weeks = 52.5 days

Speed In ft/day =  311,679.8 feet/ 52.5 days

Speed in ft/day = 5,936.76 feet/day

<em>Hence the speed in feet per day is  5,936.76 feet/day</em>

Which of the following statements must be true about this diagram? Check all that apply.
pishuonlain [190]

Answer:

Options (D), (E) and (F) are the correct options.

Step-by-step explanation:

From the figure attached,

1). Angle 4 is the exterior angle of the given triangle having interior angles 1, 2 and 3.

Therefore, by the property of exterior angle,

∠4 = ∠1 + ∠2

2). Since ∠4 = ∠1 + ∠2,

Therefore, ∠4 will be greater than ∠1

 Similarly, ∠4 will be greater than ∠2

Therefore, Options (D), (E) and (F) are the correct options.
