Glenwood High School is constructing a new concrete basketball court that will need 60 cubic yards of concrete. When mixed, one bag of concrete will fill 0.5 cubic yards. The school ordered more than enough concrete to completely fill in the court. Let x represent how many bags of concrete the school ordered. Which inequality describes the problem?

Answers

Answer 1

Answer:

The school ordered more than enough concrete to completely fill in the court, so the number of bags of concrete ordered, represented by x, must be greater than the number of cubic yards of concrete needed to fill the court. This can be represented by the inequality x > 60 cubic yards / 0.5 cubic yards/bag. Solving for x, we get x > 60 * 2 = 120. Therefore, the inequality that describes the problem is x > 120.

For his birthday, Zack and three of his friends went to a movie. They each got a ticket for $8.00 and the same snack from the concession stand. If Zacks mom paid $48 for the groups tickets and snacks how much did each snack set cost?

Answers

Answer:

$4.00

Step-by-step explanation:

There is, in total, 4 people attending the movies. [Zack and his 3 friends]

If each ticket costs $8.00, we can use 4 x $8.00 to find out how much the tickets costs.

4 x $8.00 = $32.00

If his mom paid $48 dollars in total, to get the amount of money they spent on snacks, we can use $48 - $32.

$48 - 32 = $16

We can now divide $16.00 by 4, as everyone [Zack and his 3 friends] got the same snack from the concession stand, and that leaves us with the equation: $16/4 [also known as 16 divided by 4]

$16/4 = $4.00

Each snack set cost $4.00

A student has a container with a volume of 1.5 L. She estimates the volume to be 1.8 L. By what percent is the students estimate off?

Answers

Answer:

  20%

Step-by-step explanation:

You want to know the percentage error in an estimate of 1.8 L for an actual value of 1.5 L.

Percentage error

The percentage error is the ratio of error amount to actual value, multiplied by 100%.

  Error amount = estimate - actual = 1.8 L -1.5 L = 0.3 L

  ratio = (error amount)/(actual) = (0.3 L)/(1.5 L) = 0.2

  percentage error = 0.2 × 100% = 20%

The error in the student's estimate is 20%.

What is a rectangle?

A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.

Given that the height of the poster is  2 5/8 feet.

The wide of the poster is 1 3/4 feet.

Now convert the numbers 1 3/4 feet, 2 5/8 feet mixed fraction to improper fraction:

2 5/8 feet = [(2×8) + 5]/8 = 21/8 feet

1 3/4 feet = [(1×4) + 3]/4 = 7/4 feet

The area of a rectangle space is the product of length and breadth of the rectangle shape.

The area of the poster is

(21/8) × (7/4)

Now multiply the denominators of both fractions and numerators of both fraction:

(21  × 7)/(8×4)

= 147/32

= [tex]4\frac{19}{32}[/tex] square feet

tina spends 65$ on supplies to start a dog washing business. she earns $21 every time she washes a dog. what is w, the number of dogs tina must wash to earn a profit of $40

Answers

By solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.

What are equations?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, using the  information given, the equation can be formed as:

21w - 65 = 40

Now, solve for the subject w to get the value of w as follows:

21w - 65 = 40

21w = 40 + 65

21w = 105

w = 105/21

w = 5


Therefore, by solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.

Write an equation for a rational function with the given characteristics.
Vertical asymptotes at
x = −3
and
x = 6,
x-intercepts at
(−4, 0)
and
(1, 0),
horizontal asymptote at
y = −3

Answers

Answer:

  y = -3(x +4)(x -1)/((x +3)(x -6))

Step-by-step explanation:

You want a rational function with vertical asymptotes at -3, 6; x-intercepts at -4, 1; and a horizontal asymptote at y = -3.

Vertical asymptotes

A rational function will have vertical asymptotes at the denominator zeros. Vertical asymptotes at -3 and 6 will be had if the denominator has factors (x +3) and (x -6).

X-intercepts

A rational function will have x-intercept at the numerator zeros. X-intercepts at -4 and 1 will be had if the numerator has factors (x +4) and (x -1).

Horizontal asymptotes

A horizontal asymptote will be found at the y-value that is the (constant) ratio of the highest-degree terms of the numerator and denominator. Here, we can achieve that by multiplying the factors mentioned above by the desired constant (-3).

The equation is ...

  [tex]\boxed{y=-3\dfrac{(x+3)(x-6)}{(x+4)(x-1)}}[/tex]

__

Additional comment

A "hole" will be found where a numerator and denominator factor cancel. For example, a hole at x=7 could be achieved by making the function have an additional numerator factor of (x -7) and an additional denominator factor of (x -7).

Effectively, the horizontal asymptote is the quotient of the numerator and denominator (excluding the "remainder"). If that quotient is a linear (or other) function, the graph will asymptotically approach that function as the magnitude of x gets large. A linear function gives a "slant aymptote."

Which of the following equations represents a line with a positive slope and a negative y-intercept?

Answers

The equation represents a line with a positive slope and a negative y-intercept is  y = 7.5x - 2

How to determine which equation represents a line with a positive slope and a negative y-intercept?

The slope-intercept form of the equation of a line is y = mx + c

where m is the slope and c is the y-intercept

Given: y = 3.5x, y = 1/4 x + 7, y = 7.5x - 2 and y = -5x - 8

For  y = 3.5x:

y = 3.5x

Comparing with y = mx +c

m = 3.5 and c = 0

For y = 1/4 x + 7:

y = 1/4 x + 7

Comparing with y = mx +c

m = 1/4 and c = 7

For  y = 7.5x - 2 :

y = 7.5x - 2

Comparing with y = mx +c

m = 7.5 and c = -2

For  y = -5x - 8 :

y = -5x - 8

Comparing with y = mx +c

m = -5 and c = -8

Thus, y = 7.5x - 2 has a positive slope (7.5) and a negative y-intercept (-2)

Given:

p(x) = 3x³ - 5x² - 4x + 4
