Answer: V=60
Explanation-
The first step is to find the resistance in the current with 480 volts.
The equation for resistance is= voltage/current(amps)
So the equation would be: 480/12
Solve: 480/12=40 ohms
40 is the resistance
Now you will use this the answer the seconds part.
In the second part you are finding the voltage.
Equation for voltage: V= current x resistance
So the equation would be: 1.5 amps x 40 ohms
Solve: 1.5 x 40= 60 volts

Dollars: 95 x
--------------------- = ------
Students: 20 162
Cross multiply: 95(162) = 20x
15,390 = 20x
----------------------
20 20
769.5 = x
Therefore, it will cost $769.50 for 162 students to visit an aquarium.
To find the slope and y-intercept, we first need to put this equation in Slope Intercept Form (SIF). SIF is y=mx+b where "m" is the slope and "b" is the y-intercept.
To put the equation in slope intercept form, we need to isolate y and simplify the other terms.
5x+4y=2
-5x -5x
4y=-5x+2
/4 /4
y=5/4x+2/4
y=5/4x+1/2
Using the math above, we can see that the slope is 5/4 and the y-intercept is 1/2.
Answer:
Step-by-step explanation:
let x represent the number
9x + 60 = 10x - 2
60 + 2 = 10x - 9x
62 = x <===
<span>Think about the cones with only 1 scoop of ice cream. Isn't it clear that there are 28 of those?
Now think about the two scoop cones. You have 28 choices for the first scoop and 28 choices for the second scoop.
So the number of possibilities is 28(28).
Now think of the 3 scoop cones.
You have 28 choices for the first scoop, 28 choices for the second scoop, and 28 choices for the third scoop or 28(28)(28) possibilities.
Add them all together and you have the total.
So it will be like this:
</span><span>28^3+28^2+28
