Answer:

3

Step-by-step explanation:

first work out wax used for cone using formula

1/3 x 3.14 x r squared x height

using this the total for the candle must be 113

formula for a sphere is 4/3 x 3.14 x r cubed

so we know 113 /3.14 / 4/3 = r cubed

cube root 27 = 3

#3 (1 pt) A certain baseball card is very rare and is currently worth $2000. If the price of this card increases by 3% a year,
Galina-37 [17]

Answer:

$2000x(1.03)ˣ

Step-by-step explanation:

This is known as compound interest.

100% + 3% = 103%, so we put this into a decimal: 1.03

We now put this into the equation:

$2000x(1.03)ˣ

If you want to work out the price after, say 3 years, then you would change x to 3, so the equation becomes

$2000x(1.03)³

You can then use a calculator to work out the answer.

65.<br> Evaluate a-b+c for?
Rama09 [41]

Answer:

From the problem, the answer to the equation is 5 1/10

Step-by-step explanation:

First, let's gather the information from the problem.

<em>a = 4 1/5 (also can be turned into 21/5)</em>

<em>b = 2 7/20 (also can be turned into 47/20)</em>

<em>c = 3 1/4 (also can be turned into 13/4)</em>

Now, plug in the numbers using the improper fractions.

21/5 - 47/20 + 13/4

Turn the denominators into the same number.

84/20 - 47/20 + 65/20

Subtract 84/20 and 47/20.

37/20 + 65/20

Add 37/20 and 65/20.

102/20 or 5 1/10

So, your answer to this equation is 5 1/10.
