Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.19 cm and a height of 6 cm. Each solid block will have a volume of 360 cm3. How many cylinders of gold will it take to mold one block of gold?

Answers

Answer 1

Answer: so volume of a cylinder=area of top circle times height or
pi times radius^2 times height
diameter=2 times radius
diameter times 1/2=radius
6.19/2=radius=3.095
pi times 3.095^2 times 6=177.077
so volume of cylinder=177.08
volume of gold=360
so
x cylinders=1 solid block
diviide both sdies by cylinder
x=block/cylinder
block=360
cylinder=177.08
360/177.08=2.03
so aprox 2.03 cylinders will make one block
round down since 0.03 is nigligible
the answer is 2

sales tax and purchase price: suppose the sales tax rate in a certain state is is 8% how much sales tax is charged on a new car if the purchase price is $11,900?

Answers

To calculate the sales tax of an $11,900 purchase, we simply multiply the purchase prices by the sales tax rate.

8% is 8 parts of 100, which can be shown as a fraction with 8/100 or as a decimal with .08

Let's use the decimal in this case:

Sales Tax = purchase price x sales tax rate
Sales tax = 11,900 x .08
Sales tax = $952

So if the car was purchased at $11,900 in a state with an 8% sales tax rate, the sales tax would be $952 bringing the total cost of the car up to $12,852.

Final answer:

The question, which pertains to algebra, is asking for the solution to three equations involving three numbers. To solve the problem, we set up equations based on the information provided and then solve for the three unknowns. The solution is 10, 24, and 14.

Explanation:

This problem can be addressed using algebraic equations. We are given three unknown numbers a, b, and c. The problem provides us with the following information:

The average of a, b, and c is 16, which means the sum of the three numbers is 48 (because 16 * 3 = 48).
The second number, b, plus 20 equals the sum of the other two, a + c.
The third number, c, equals the sum of the first two numbers minus four, or a + b - 4.

Using these equations, we can solve for a, b, and c. Our steps are:

Substitute the values of a + b from the third equation into the second to get b + 20 = 2b - 4.
Solve this equation to get b = 24.
Substitute b = 24 into the first equation to get a + c = 24. This means a = c.
Substitute a = c into the third equation to get 2a = 28, or a = c = 14.

So, the three numbers are 10, 24, and 14.

X^{2} -25=0 Please help meeee

Answers

Answer:

$x=5,x=-5$

Step-by-step explanation:

$x^2-25=0$

Add 25 to both sides:

$x^2-25+25=0+25$

$x^2=25$

Square root both sides:

$x=√(25),\:x=-√(25)$ (Since a negative number multiplied by itself gives positive, there are two answers.)

$x=5,x=-5$

Hey there!

ANSWER: $x=5\nx=25$

EXPLANATION:

$x^2-25=0$

The first step we have to do is to add 25 to both sides of the equation.

$x^2-25+25=0+25\n\text {equals }x^2=25$

In our last and final step, we will have to take the square root.

$x=$ ± $√(25)$

We have two answers.

$x=5(ANSWER)\nx=-5(ANSWER)$
