<span>The answer is 0.135

Using the calculator, </span><span>e^-2 = 0.13533528323

Since we want to round it to three decimal places, we are interested in the 3rd and the 4th decimal places. If the 4th decimal place is bigger than 5, we should increase the 3rd decimal place by 1. If it is smaller than 5, then the 3rd decimal place remains the same. In our case, the 4th decimal place is 3, which is smaller than 5, therefore, the 3rd decimal place will remain the same:

Rounding 2.199. The tenths digit is 1, which is 4 or less, so you will round down. Re-write 2.199 without the decimal places: 2 . So 2.199 rounds to 2.

Imelda rode her bicycle 39 kilometers. If 1 meter = 1.094 yards, find the distance Imelda rode her bicycle to the nearest mile.
Alborosie

Answer: 24.24 miles

Step-by-step explanation:

We should note that 1000 metres = 1 kilometer.

Imelda rode her bicycle 39 kilometers which will be converted to meters a:

= 39 × 1000

= 39000 meters

Since 1 meter = 1.094 yards

39000 meters = 39000 × 1.094 = 42666 yards

To find find the distance Imelda rode her bicycle to the nearest mile goes thus:

1 mi = 1760 yd

42666 yards will be converted to miles. This will be: 42666/1760 = 24.24 miles

PLEASE HELP I AM STUCK ON THIS
Fofino [41]

Answer:

Step-by-step explanation:

This is a right triangle problem.  The reference angle is x, the side opposite the reference angle is 32, and the hypotenuse is 58.  The trig ratio that relates the side opposite a reference angle to the hypotenuse is the sin.  Filling in accordingly:

sin(x)=\frac{32}{58}

Because you are looking for a missing angle, you will use your 2nd button and then the sin button to see on your display:

sin^{-1}(

Within the parenthesis enter the 32/58 and you'll get your angle measure.  Make sure your calculator is in degree mode, not radian mode!!!

kow [346]

Answer:

1479 people

Step-by-step explanation:

If the amount employed is 8381, that means 8381 is 85% of the population. 8381/85 = 98.6

Every 1% of the population is 98.6, so we can just do 15 x 98.6 to get 1479

If y is directly proportional to x and y = 5 when x =2, what is the value of y when x=6
sammy [17]

Answer:

y=15

Step-by-step explanation:

The formula for direct variation is

y = kx

5 =k*2

Solve for k

Divide by 2

5/2 = k

y = 5/2 x

Now we substitute x=6

y = 5/2(6)

y = 15
