Complete the sentence.<br><br><br> 7 is 35% of _________.
Sonbull [250]
<span>Okay, pretend the number equals X,
so x is 35%, and that would equal 7, so then 
x is still 35/100 = 7 
x = 7 which is 100/35 
x = 700/35 
x = 20 
then you get the number = 20 
I hope this was helpful, and good luck! :P</span>

A conveyor belt carries supplies from the first floor to the second floor, which is 26 feet higher. The belt makes a 60° angle w
tamaranim1 [39]
<h3>Answer:</h3>

30 ft; 0.4 min

<h3>Step-by-step explanation:</h3>

The mnemonic SOH CAH TOA reminds you ...

... Sin = Opposite/Hypotenuse

Here, the angle of elevation is opposite the triangle side representing the distance between floors. The hypotenuse is the length of the conveyor belt. Rearranging the formula (by muliplying by Hypotenuse/Sin), we get ...

... Hypotenuse = Opposite/Sin

Filling in the values from this problem, we have ...

... length of conveyor = (26 ft)/sin(60°) ≈ 30 ft

The time it takes to travel that distance is given by ...

... time = distance/speed

... time = (30 ft)/(75 ft/min) = 2/5 min = 0.4 min

A bathtub is being filled at a rate of 4 liters per minute. Can this situation be
geniusboy [140]

Answer:

<em>Yes, this is a linear function because the rate of change is constant</em>

Step-by-step explanation:

<u>Linear Functions</u>

We can recognize a linear relation between variables x and y when they can be represented by a formula like

y=mx+b

Where m is the rate of change and it has a constant value. More specifically, a proportional relationship is a special case where b=0, meaning that every value of y divided by the corresponding value of x, is constant.

The situation described in the question says a bathtub is being filled at a rate of 4 liters per minute. It means that every minute, 4 liters are constantly being added to the existing quantity. This is a constant rate of change, so the correct answer is

"Yes, this is a linear function because the rate of change is constant"
