Step-by-step explanation:

If all the tickets were adult tickets, the total cost would be $3200.

subtract $3 for every child ticket

3200-2750= 450 so we need to subtract $450

450/3 is 150 so there are 150 children tickets

Which of the following is the formula for the volume of a pyramid with base area B and height h?

kolezko [41]

Answer:

Correct choice is A.

Step-by-step explanation:

We have to find about which of the given choices is the formula for the volume of a pyramid with base area B and height h.

We know that formula of volume of pyramid is given by:

$volume = \frac{1}{3}\left(Base\ area\right)\left(Height\right)$

Plug the given values

$volume = \frac{1}{3}\left(B\right)\left(h\right)$

So the correct choice is A.

What is the total surface area of the pyramid in square feet?

Elis [28]

Base is 12 feet square so 12 *12 = 144 square feet

each triangle has base of 12 feet and height of 8 feet
area of triangle = 1/2 x base x height = 1/2 x 12 x 8 = 48 square feet

48 x 4 triangles = 192 square feet

total: 192 + 144 = 336 square feet

The circle below has a center D and its diameter is 10 feet. Given that m angle A D B equals 35 degree, find the length of major

goldfiish [28.3K]

The length of major arc ACB with angle measure of 325° and diameter of 10 feet is (325/36)π

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

angle of arc ACB = 360° - 35° = 325°

The length of major arc ACB = (325/360) * π * 10 = (325/36)π

The length of major arc ACB with angle measure of 325° and diameter of 10 feet is (325/36)π

A system of equations is given below. y=1/2x-3 and -1/2x-3. Which of the following statements best describes the two lines?

pantera1 [17]

"They have different slopes but the same y-intercept, so they have one solution" is the statement which best describes the two lines.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equations:

$y=\left(\frac{1}{2} \times x\right)-3$

$y=\left(-\frac{1}{2} \times x\right)-3$

As we know that the slope intercept form of a line is

y = m x + c

So, from equation 1 and equation 2 we can see that

$m_{1}=\frac{1}{2} \quad \text { and } c_{1}=-3$

$m_{2}=-\frac{1}{2} \text { and } c_{2}=-3$

So, from the above expressions, we can say that both lines have different slopes but have same y – intercept with one common solution when x = 0.
