7 0

Volume of the cone is 942 cm³

Step-by-step explanation:

  • Step 1: Find the volume of the cone given base area = 78.5 cm² and height = 12 cm

Volume of the cone = Base area × Height

                                 = 78.5 × 12 = 942 cm³

Liula [17]

Answer:

Equation: 8.5t+6.5=57.5

Solution: t=6

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

8.5t

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

8.5t+6.5

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

8.5t+6.5=57.5

Finally, you can solve for "t" in order to find the solution of the equation. This is:

8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6

Which expression is equivalent to 4 (3n - 5)?
mart [117]

Expression 4 (3n - 5) is equivalent to <em><u>C: 12n - 20</u></em>

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

  • 1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

  • 2. variable

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

  • 3. constants

is a fixed value, can be a number

  • 4. arithmetic operations  ⇒ +, - , : , x

Calculation operations include multiply, divide, add, substract, etc.

There are several properties in integer multiplication operations

  • 1. closed property

Multiplication between integers will produce integers too

  • 2. commutative property

a x b = b x a

  • 3. associative property

ax (bxc) = (axb) xc

  • 4. identity

ax1 = 1 x a = a

  • 5. distributive  property

*<em> addition </em>

ax (b + c) = axb + axc

* <em>substraction </em>

ax (b-c) = axb - axc

We can use distributive  property  of <em>substraction   </em>to solve the problem

\displaystyle =4(3n-5)\\\\=4x3n - 4x5\\\\=12n-20

"Equivalent to" means having the same value.

From the answer choices , which produce the same expression is C. 12n-20

choose the standard form of the equation of the circle with radius 5 √ 3 centered at( -6, 2) please help ​
Ilia_Sergeevich [38]

Answer:

(x + 6)² + (y - 2)² = 75

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, 2) and r = 5\sqrt{3}, hence

(x - (- 6))² + (y - 2)² = (5\sqrt{3} )², that is

(x + 6)² + (y - 2)² = 75
