Answer:
1. he can go up to 4 rides
2. she can buy 3 flowers
Step-by-step explanation:
1. 19 >= 5+ 3x
19 - 5 >= 3x
14 >= 3x
If you solve this you can get 4 and balance 2
2. 40 >= 2 + 11x
38 >= 11x
If you solve this you can get 3 and balance 5
Multiply 5 for both the numbers in the ratio.
you will get 10 boys and 15 girls which sum to 25 players.
Hope this helps :)
(2/3) x + (2/5) x
(10/15)x + (6/15) x = (16/15) x
Answer:
Question 21: C.
Question 22: I.
Question 23: E.
Question 24: B.
Step-by-step explanation:
#21: The first statement is presented in the "Given" section.
#22: Since the reflexive property states that anything is equal to itself, BC ≅ BC.
#23: C being the midpoint of AD means that C is the same distance from both point A and point D. This then means that AC ≅ CD.
#24: AB ≅ DB due to the given, BC ≅ BC (since it's the same side), and we've proven that AC ≅ CD using a midpoint. We've proven <em>all three sides</em> on the two triangles to each other are congruent. This means that we've proven the triangles using SSS, which is B.
<span>The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.
Explanation<span>:
We start out with the ratio 207 km/1 hr.
We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.
We know that 1 hr = 60 minutes, so we have 207000 m/60 min.
We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.
Dividing this, we get 57.5 m/s.
In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.</span></span>
