Answer:

A: x > 3/4

Step-by-step explanation:

First you simplify the equation.

Simplify 1/3x

Then Simplify the left side.

1/2-x/3<x/3

Move x/3 to the left side of the equation by subtracting it from both sides.

1/2-x/3-x/3<0

Now simplify the left side.

1/2-2x/3<0

Find the LCD of the terms of the equation. In this case it's 6.

Multiply each term by 6 and simply.

3-2x<2x

Move all terms that contain a x to the left side of the inequality.

3-4x<0

Subtract 3 from both sides.

-4x<-3

Now divide each term by -4 and simplify.

This gives us our answer of x > 3/4.

Hope this helps. :)

Final answer:

The large box weighs 13.5 kilograms and the small box weighs 6 kilograms.

Explanation:

To solve this problem, we can assign variables to represent the weight of each type of box. Let's say the weight of a large box is L and the weight of a small box is S.

From the given information, we can set up a system of equations:

2L + 5S = 57 (Equation 1)

8L + 3S = 126 (Equation 2)

We can solve this system of equations using the method of substitution or elimination. Let's use elimination:

Multiply Equation 1 by 8 and Equation 2 by 2 to eliminate the S variable:

16L + 40S = 456 (Equation 3)

16L + 6S = 252 (Equation 4)

Subtract Equation 4 from Equation 3:

34S = 204

Solve for S: S = 6

Substitute the value of S into Equation 1:

2L + 5(6) = 57

2L + 30 = 57

2L = 27

Solve for L: L = 13.5

Therefore, the large box weighs 13.5 kilograms and the small box weighs 6 kilograms.

Answer:

60%

Step-by-step explanation:

p/100 = 18/30

Multiply each side by 100

p/100 *100 = 18/30 *100

p = 60

18 is 60 percent of 30

The number 18 out of the number 30 is 60 percent.

We need to find what percent is 18 out of 30.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, 18/30

= 9/15

= 3/5

= 0.6

In percentage 0.6×100

= 60%

Therefore, the number 18 out of the number 30 is 60 percent.

Answer:

-2

Step-by-step explanation:

We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.

Recalling the rules for a horizontal asymptote:

1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.

2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.

3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.

Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.

Horizontal asymptote = [tex]-\frac{2}{1}[/tex] = -2

Answer:

It's B.

Step-by-step explanation:

A trunk has six faces . The total  surface area will be the sum of the areas of these faces.

The surface area of a rectangular prism (like a trunk) is the total area of the surface of the object and can be found using the formula A = 2lw + 2lh + 2wh, where 'l' represents length, 'w' represents width and 'h' represents height.

The surface area of a trunk, or any three-dimensional object, refers to the total area that the surface of the object occupies. In the case of a trunk, if we consider it as a rectangular prism (a box shape), that surface area can be found by adding the areas of all six faces of the prism. The formula to calculate the surface area (A) of a rectangular prism is A = 2lw + 2lh + 2wh where l denotes length, w width, and h height. Let's say, for example, that your trunk has a length of 3 units, a width of 4 units, and a height of 2 units. The surface area would then be 2*(3*4) + 2*(3*2) + 2*(4*2) = 24 + 12 + 16 = 52 square units.

Answer:

all reals, except at x=0

Step-by-step explanation:

because x is in the denominator, x cannot equal 0

For this case we have a function of the form [tex]y = f (x),[/tex]where:

[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]

we must find the domain of the function.

The domain is given by all the values for which the function is defined.

Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.

[tex]\large\boxed{\text{The slope}\ m=3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in the standard form:

[tex]12x-4y=3[/tex]

Convert to the slope-intercept form:

[tex]12x-4y=3[/tex]         subtract 12x from both sides

[tex]-4y=-12x+3[/tex]        divide both sides by (-4)

[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]

Answer:  The required slope of the given line is 3.

Step-by-step explanation:  Given that Helaine graphed the following equation :

[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to find the slope of the line.

We know that

the slope-intercept form of a straight line is given by

[tex]y=mx+c,[/tex] where m is the slope of the line.

From equation (i), we have

[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]

Comparing with the slope-intercept form, we get

slope, m = 3.

Thus, the required slope of the given line is 3.

Answer:

Step-by-step explanation:

A. 250 x .32 = 80

B. 250 x .44 = 110 So, the answer is berries.

Final answer:

Out of 250 surveyed individuals, 80 people prefer peaches. Berries are the preferred choice of more than 100 people.

Explanation:

A total of 250 people were surveyed about their favorite fruit. To find out how many people prefer peaches, we calculate 32% of 250 people. This calculation is done by multiplying the total number of people by the percentage of those who prefer peaches:

250 people x 32% = 250 x 0.32 = 80 people

Therefore, 80 people prefer peaches.

To determine which type of fruit more than 100 people prefer, we apply the same calculation method. Here are the calculations:

Berries: 250 x 44% = 110 people

Peaches: 250 x 32% = 80 people

Cherries: 250 x 24% = 60 people

More than 100 people prefer berries.

Answer:

79

Step-by-step explanation:

A square that has side length [tex]l=2 ft[/tex] has area [tex]2^2=4ft^2[/tex].

A circle that has a diameter 20 feet has area [tex]A=\frac{\pi d^2}{4}[/tex]

We substitute the diameter into the formula to obtain;

[tex]A=\frac{\pi \times 20^2}{4}=100\pi ft^2[/tex]

The number of squares that has area 4 feet square that can fit into a circle with area [tex]100\pi ft^2[/tex] is

[tex]=\frac{100\pi}{4}=25\pi=78.5398[/tex]

When we round to the nearest whole number; we have 79 squares.

Approximately 79 squares of size 2 ft by 2 ft can fit into a circle with a diameter of 20 feet.

To accurately determine how many 2ft by 2ft squares can fit into a circle with a diameter of 20 feet, let's perform a step-by-step calculation:

1. Calculate the area of the circle:

 [tex]\[ \text{Area of the circle} = \pi r^2 \][/tex]

  Given the diameter is 20 feet, the radius r is 10 feet:

[tex]\[ \text{Area of the circle} = \pi \times 10^2 = 100\pi \approx 314.16 \text{ square feet} \][/tex]

2. Calculate the area of one 2ft by 2ft square:

[tex]\[ \text{Area of one square} = 2 \times 2 = 4 \text{ square feet} \][/tex]

3. Calculate the theoretical maximum number of squares that can fit into the circle by dividing the area of the circle by the area of one square:

[tex]\[ \text{Theoretical number of squares} = \frac{\text{Area of the circle}}{\text{Area of one square}} = \frac{314.16}{4} \approx 78.54 \][/tex]

4. Round to the nearest whole number:

[tex]\[ \text{Rounded number of squares} = 79 \][/tex]

t - 7 = -8

t = -1

Final answer:

The correct solution to the equation -3(t-7) = 24 is t = -1, which contradicts the reference indicating solutions for a different quadratic equation.

Explanation:

The equation presented, -3(t-7) = 24, does not yield the solutions t = 3.96 and t = -1.03 as the provided reference indicates. Instead, those solutions seem to be related to a different quadratic equation. To solve the given linear equation for t, you need to perform the following steps:

Therefore, the solution to the equation -3(t-7) = 24 is t = -1.
