True, it has a 90 degree angle. It’s clear as day. And the Pythagorean theorem works perfectly fine with the two legs and hypotenuse
5x + 6
5x = number of buffets purchased.
6 = 3 * 2 (three friends bought 3 $2 drinks)
A*b=18 ____[1]
a+b=19____[2]
[2] a=19-b ___[3]
put [3] in [1]
(19-b)*b = 18
19b-b^2 = 18
b^2-19b+18 = 0
(b-18)(b-1) = 0
so b=18 or b=1
if b=18 then a=19-18=1
if b=1 then a=19-1=18
SO two factors are 1 and 18
So the smoothie would be d+4.50
When it says $4.50 MORE than, it would be adding it to d or the original amount! I hope this helps!
Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
<h3>What was Ryashkina's average walking rate?</h3>
Rate or speed is expressed as distance walked or traveled per unit time.
R = s/t
Given the data in the question;
- Distance covered s = 10,000m
- Time elapsed t = 41 minutes 56.23 seconds
- Rate r = ?
First convert 41 minutes to seconds.
⇒ 41min = ( 41 × 60 )s = 2460sec
Now, Elapsed time t = 2460s + 56.23s = 2516.23 second
Next, we determine the rate.
R = s / t
R = 10000m / 2516.23 s
R = 3.97m/s
Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
