Answer:
Step-by-step explanation:
The drama club is running a lemonade stand to raise money for its new production. A local grocery store donated cans of lemonade and bottles of water. Cans of lemonade sell for $2.50 each and bottles of water sell for $1.25 each. The club needs to raise at least $600 to cover the cost of renting costumes. The students can accept a maximum of 460 cans and bottles.
Write a system of inequalities that can be used to represent this situation.
The club sells 144 cans of lemonade. What is the least number of bottles of water that must be sold to cover the cost of renting costumes? Justify your answer
Answer:
120ft/sec
Step-by-step explanation:
Assuming that there is no acceleration, divide the amount of feet (720) with the time (6 seconds):
720 ft/6 sec = 120 ft/1 sec
For every second, the skydiver drops 120 ft.
120ft/sec.

30.05 times 10= 300.5 you just move the decimal point further back
We are given the equation that represents a direct variation 2x - 4y = 0 .
<em>We know direct variation equation y = k x.</em>
Where x is the constant of variation.
In order to find if given equation is really a direct variation, we need to solve it for y.
2x - 4y = 0
Subtracting 2x from both sides, we get
-4y = -2x.
Dividing both sides by 4, we get
y = 1/2 x.
On comparing with direct variation equation y = k x. We can see that y = 1/2 x is also a direct variation equation.
And k = 1/2.
<h3>Therefore, correct option is A. Yes; k = 1/2.</h3>
