So for the first 8, we need to find the value. The way I would find the value would be to find it's place value. So I know that the 8 is in the millionths period. So the value of the eight would be in the millionths. So I think it would be 8,000,000. So that would be the answer. The 8's value is 8,000,000 because of it being in the millionths period.

Hope that helped! :D

Find the real numbers x and y.<br> 27+yi= 11-x + 4i

Korvikt [17]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:x = -16$

$\qquad \tt \rightarrow \: y =4$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 27 + yi = 11 - x + 4i$

$\qquad \tt \rightarrow \: yi + x = 11 + 4i - 27$

$\qquad \tt \rightarrow \: x + yi = - 16 + 4i$

By equating both equations we get :

$\qquad \tt \rightarrow \: x = - 16$

$\qquad \tt \rightarrow \: y = 4$

for every 140 feet that kelly rides on her bicycle, the wheels turn 20 times. about how many times do the wheels turn in 5 miles

lana [24]

Answer:

184800 times

Step-by-step explanation:

The first step is to find out how many times the wheels turn in one foot. The ratio of rotations per minute is 20:140. This can be simplified to 1:7, meaning there is 1/7 of a rotation for every 1 foot.

Next, we need to find out how many times they turn in one mile. The ratio is 1:7, and the 1 needs to become 5280. To do this, multiply both sides of the ratio by 5280. You will get 5280:36960, meaning there is 36960 rotations every mile (the ratio of miles to rotations is 1:36960).

Now, multiply 1:36960 by 5 to get the amount of rotations per every 5 miles. You will get 184800.

Final answer: the wheels turn 184800 times in 5 miles.
