ANSWER:

1616 ft³

STEP-BY-STEP EXPLANATION:

We have that the formula to determine the volume of the cylinder is as follows:

The radius is equivalent to half the diameter, therefore the radius is equal to 3.5 ft (7/2) while the height, in this case, is equivalent to the length, so it is equal to 42 ft. Therefore, we replace each value and calculate the volume, like this:

The volume of the cylindrical pipe is 1616 ft³.

Letter A doesn't show rotational symmetry of 180 degrees.

The letter 'A' has just one vertical line of symmetry.A vertical line of symmetry is that line which runs down a picture thus dividing it into two identical halves. In other words, it's a straight standing line that divides an image or shape into two identical halves.

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the form of the object looks the same. Many geometrical shapes appear to be symmetrical once they are rotated 180 degrees or with some angles, clockwise or anticlockwise. A number of the examples are square, circle, hexagon, etc.

The slope (rate of change) of the graph shown is 31.3 miles per gallon.

An equation is an expression that shows the relationship between two variables and expressions.

Slope is the ratio of vertical rise to horizontal run. It is given by:

Slope = rise / run

The point passes through (10, 313) and (20, 626), hence:

Slope = rise/run

Slope = (626 - 313) / (20 - 10) = 31.3

Using distribute property on 41×8 is 328.

What is the Distributive Property?

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.

We know that,

Distributive property is  A × (B + C) = AB + AC.

So, 41 × 8 is  41 × (5 + 3 ) = 41×5 + 41×3

                    41 × (5 + 3 ) = 205 + 123

                    41 × (5 + 3 ) = 328

For the given values the equation of new line is  y = -3x - 17

The formula for these lines is y = mx + b, where m denotes the slope and b the y-intercept. Our line has a slope of 3 and a y-intercept of -5, which we know from the question. By entering these numbers, we obtain the equation of our line as y = 3x - 5.

Given,

The equation of line is y= -3x+4

as the lines are parallel,

slope of lines will be same,

∴ Slope of new line = -3

The equation of line is:

y - y1 = m(x - x1)

Where x1, y1 are the given coordinates and m is the slope

⇒ y -(-5) = -3 (x - (-4))

The minimum value of the parabola is y = -6

An equation of a parabola is given as

y = x²-6

We will find its minimum value using the differentiation method.

For this first we will find the derivative with respect to x and find the value of x at which the derivative becomes zero. The derivative becomes zero only when the parabola has either a maximum or minimum value. We further check whether the parabola has a minimum or maximum at that x by finding the second derivative of the parabola at that x.

So first derivative of y with respect to x is 2x.

So 2x = 0

⇒ x =0

Now take the second derivative of y with respect to x at x = 0,

Second derivative = 2 > 0 at x = 0

Here the second derivative is greater than zero at x = 0. So y has a minimum value at x = 0

The minimum value of the parabola is,

Answer: The answer is 570.

Step-by-step explanation:

So, if you know what numbers are, when you round, this question is easy. If you take a number line and put 570 on the left side and 580 on the right side, and 575 in the middle, you almost got it. Since the number we want to round is 573, we put it in the middle of 570 and 575. And since the number is closer to 570 than 580, the answer is 570. Your welcome!

Step-by-step explanation:

You are in charge of planning your mother's surprise party. You have found a hall that rents for $225 and a caterer that will charge you $15 per guest. Write an inequality to calculate your total cost (T) based on the number of guests (g).

T = 15g + 225

If you have a total budget of $1000 how many guests can you

invite?

1,000 = 15g + 225

subtract 225 from both sides:

1,000 -225 = 15g + 225 - 225

775 = 15g

divide both sides by 15:

775/15 = 15g/15

g = 51.66

Because you cannot invite part of a guest round down to inviting 51 guests

There is a 0.765 percent chance that the flight will leave on time when it is not raining.

Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty.

Given a 0.1 delay probability, the probability of the airplane departing on time is 1-0.1 = 0.9.

The likelihood that it won't rain is 1-0.15 = 0.85.

3) Alex had 20 video games at the beginning.

2) The strategy to solve the problem backward is:

The number of games Alex has now is 16 games.

The number of games he gave to his brother is 2, so add 2 to the current number of video games, 16 + 2 = 18

Now add the games he sold, which are given as 3

18 + 3 = 21

Subtract the games he traded with Hector,i.e. 6 video games

21 - 6 = 15

This obtained number is 3/4 of his games,

3/4 of the total video games = 15

Therefore, the total video games were = (15×4)/3 = 20

4) Yes the answer makes sense.

Operations in reverse order are:

The number of video games given by Alex to hector is = 1/4 of 20 = 5

Remaining video games = 20 - 5 = 15

Number of games after adding exchanged 6 video games = 15+6 = 21

The formula for the nth term of the arithmetic sequence whose first term is 7 and the common difference is -3 is -  a[n] = 10 - 3n

An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. A sequence -

a₁ , a₂, a₃ , a₄ ...... aₙ

will be an arithmetic progression if -

a₂ - a₁ = a₃ - a₂ = a₄ -  a₃ = d (constant) is called common difference of A.P. and a₁ = 'a' as the first term.

Given is the the first term equal to 7 and the common difference equal to

- 3.

We can calculate the nth term of an A.P. using the formula -

a[n] = a + (n - 1)d

a[n] = 7 + (n - 1)(- 3)

a[n] = 7 - 3n + 3

a[n] = 10 - 3n

Answer:

(a)Adult:10.99+0.99x, Kid: 5.99+0.99x

(b)Adult's Total cost = $15.94, Kid's Total cost =$10.94

Explanation:

Cost of a ride = $0.99

Let x be the number of rides.

Cost of an Adult Ticket = $10.99

An equation for adult tickets will therefore be: 10.99+0.99x

Similarly, the cost of a kid ticket =$5.99

An equation for adult tickets will therefore be: 5.99+0.99x

(b)If they ride 5 tickets each, the amount of money spent will be:

x=5 rides

Total cost for an adult=10.99+0.99(5)

=$15.94

Total cost for a kid = 5.99+0.99(5)

=5.99+4.95
