The correct answer should be -True, 8 lines.
I = / r where I = current and r = resistance
80 = k / 50 so
k = 400
so we have I = 400/r
when r = 40
I = 400/40 = 10 amps
Answer: See below.
Step-by-step explanation:
Let's go number by number.
Rational pretty much means you can put it into a fraction of whole numbers.
The first number is -81,572.
- This number is <u>rational</u> because it can be put into a fraction (
) that is made up of whole numbers.
The second number is
.
- This number is <u>irrational</u> because it cannot be put into a fraction of whole numbers.
- Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.
The third number is 5.636336333
- There is a pattern so the number is <u>rational</u>.
- Usually a pattrn means it can be put into a fraction.
The fourth number is
. This equals 4 if you solve it out.
- Since we just get 4, that certainly can be put into a fraction of whole numbers, so this is <u>rational.</u>
Im not to sure bc there isnt an age with the brother so whatever 6 plus b is
Answer:25 months
Step-by-step explanation: Let's make the equations first,
Plan A: 70x Plan B: 50x+500
Now we make it into an equivalent equation:
70x=50x+500
Then we solve:
70x=50x+500
-50x -50x
20x=500
÷20 ÷20
x=25
To check if it's correct, we just plug it in:
70(25)=50(25)+500
1750=1750
