Victor measured a circular lid and found d, the diameter, was 8 inches and c, the circumference was 25 inches.
Answers
Answer:
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.
Step-by-step explanation:
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."
We want to find the value of and solving from the last equation we got:
And replacing we got:
So then the approximation for the value of and that's very close to the real value of
Step-by-step explanation:
For this case we know that the diameter d =8 in. And we can find the radius from this info since d = 2r with r representing the radius. If we solve for r we got:
And we also know that circumference C =25 inches and the formula for this circumference is given by:
We want to find the value of and solving from the last equation we got:
And replacing we got:
So then the approximation for the value of and that's very close to the real value of

Ohm's law states that V=IR for a simple circuit, where V is the total voltage, I is the amount of current running through the resistor and R is the resistance of the resistor. If I=40 amperes when R=3 ohms, find the amount of current (in amperes) when the resistor has a resistance of 20 ohms. Assume voltage remains constant.

CFMS has contacted a band to play at an upcoming event. The band will charge a travel fee of $525 plus $12.50 per ticket sold.The school decides to turn the event into a fundraiser by increasing the cost of the tickets. If they want to make a profit of $875, how much will they need to charge per ticket?
Answers
Answer:
x=28 so they need to charge 28 tickets
Step-by-step explanation:
525 + 12.50x=875
First, take the 525 and drag it to the other side which will become into negative so the equation will be 12.50x=875-525 now just subtract it and u will get the answer of 12.50x=350 now all you need to do is divide [tex]\frac{350}{12.5}[/tex] and now the answer will be x=28 to double check we can just multiply 12.5 times 28 = 350 now plus 525 is = to 875 hope this helped :>

What is the length of the hypotenuse of the triangle?
Answers
Step-by-step explanation:
Hey there!
Here;
ABC is a Right angled triangle.
Taking reference angle as angleA.
Now;
Hypotenuse (h) = AB
Perpendicular (BC)= 24 ft.
Base(AC)= 10 ft.
Now, Using Pythagoras relation;
[tex]h = \sqrt{ {p}^{2} + {b}^{2} } [/tex]
Put all values.
[tex]h = \sqrt{ {24}^{2} + {10}^{2} } [/tex]
Simplify it.
[tex]h = \sqrt{576 + 100} [/tex]
[tex]h = \sqrt{676} [/tex]
Therefore, h= 26ft.

Answers
Answer:
Part A: She borrowed: 3700
Part B: She would pay 555 in interest.
Step-by-step explanation:
Since, simple interest is,
Where, P is the principal amount,
r is the annual rate of interest,
t is time ( in years ),
Part A : Here, S.I. = $ 444,
t = 3 years,
r = 4 %,
Thus,
Hence, She borrowed $ 3700.
Part B :
Here, r = 5 %, t = 3 years, P = $ 3,700,
Hence, She would pay $ 555 interest.

The fraction set up is basically subtracting 4x^3y^4 from 2y^3.
Subtract 4 from 2 and you will get 2 which will leave you with 2x^3y^4.
Now subtract the y^4 from y^3. You will end up with y^1 but you write it as y signaling its by itself (or is a 1).
You end up with 2x^3y.
