If tyler deposits $2000 of the $3200 he has earned in a account that pays 8% interest compounded quarterly. What is the formula
tester [92]
For the first quarter you would use the equation of $2000+(2000 times 0.08)=the money for the first quarter or $2160. the second quarters equation is $2000+(2000 times 0.08)2= the money for the second quarter or $2320. the thirds quarters equation is $2000+(2000 times 0.08)3= the money for the third quarter or $2480. The fourth quarters equation is $2000+(2000 times 0.08)4=the money for the fourth quarter or $2640.

PLS HELP I WILL GIVE BRAINLIEST PLS
Serhud [2]

Answer:

B.

Step-by-step explanation:

x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.

A thermos in the shape of a cylinder is filled with coffee. The height of the cylinder is 12 inches and its radius is 2 inches.
emmainna [20.7K]

Answer:

Option C is correct

Volume of coffee in the thermos is, 150.8 cubic inches

Step-by-step explanation:

Volume of the cylinder is given by:

V =\pi r^2h

Where

V is the volume of the cylinder

r is the radius

h is the height of the cylinder respectively

As per the statement:

A thermos in the shape of a cylinder is filled with coffee.

the height of the cylinder is 12 inches and its radius is 2 inches

⇒ h = 12 inches and r = 2 inches.

Substitute the given values and use \pi = 3.14 in [1]

then;

V =3.14 \cdot 2^2 \cdot 12

V =3.14 \cdot 48

Simplify:

V  ≈150.8 inches.

Therefore, the volume of coffee in the thermos is, 150.8 cubic inches
