So make a square and then you an answer from (0,1) to (4,3) the slope is 1/2 in simplest form, but for a more accurate answer a calculator.
Answer:
Step-by-step explanation:
4.5b + 8.5c = 175
b + c = 22.......b = 22 - c
4.5(22 - c) + 8.5c = 175
99 - 4.5c + 8.5c = 175
-4.5c + 8.5c = 175 - 99
4c = 76
c = 76/4
c = 19......there are 19 cats
b + c = 22
b + 19 = 22
b = 22 - 19
b = 3 <==== there are 3 birds
The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
<u>Step-by-step explanation:</u>
Let the speed of wind and speed of plane in still air are w and p km/h respectively.
The effective speed on onward journey was
................(1)
The effective speed on return journey was
..............(2)
Adding equation (1) and equation (2) we get,
⇒ 
⇒ 
⇒ 
Putting value of
in
we get:
⇒ 
⇒ 
⇒ 
Therefore ,The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
Answer: 100
Step-by-step explanation:
(10^-3)(10^5)
1/10^3*10^5 (I applied the negative power rule x^-a=1/x^a)
1/1,000*10^5
1/1,000*100,000
100,000/1,000=100
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! I also hope you had a great Superbowl Weekend! :-)
