3x-4 needs to equal or be below 8

rearrange the formula to 3x,=8+4

so 3x<=12

12/3 = 4

The triangle with side lengths of 32, 60, and 68 is a right triangle is true.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We can use the Pythagorean theorem to check if a triangle with side lengths of 32, 60, and 68 is a right triangle:

a² + b² = c²

where a, b, and c are the side lengths of the triangle and c is the hypotenuse.

Plugging in the values, we get:

32² + 60² = 68²

Simplifying:

1024 + 3600 = 4624

So, the equation holds true, which means that the triangle with side lengths of 32, 60, and 68 is a right triangle.

To calculate the density of an unknown liquid given its mass of 6g and volume of 12.0mL, divide the mass by the volume, resulting in a density of 0.5 g/mL.

To find the density of an unknown liquid with a volume of 12.0mL and a mass of 6g, you need to use the formula for density which is density = mass/volume. Given the mass is 6g and the volume is 12.0mL, you substitute these values into the formula to calculate the density.

Therefore, the calculation would be: density = 6g / 12.0mL = 0.5 g/mL.

This states that the density of the unknown liquid is 0.5 g/mL, which means for every milliliter of this liquid, it weighs 0.5 grams. Understanding the density of a substance can be crucial in identifying it since density is a characteristic property.

You need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

The process of transformation under translation means that the figure is simply change into another position. That is, the angles, the lengths or any other characteristic is unchanged except for the position of the figure in the Cartesian coordinate alone.
We are given the function in the form of:

f(x) = x^2

Which can also be written as:

y = x^2

Since the translation made is to move the figure 7 units up, then this means that the y coordinate is increased by 7. The given equation is a parabola pointing up with vertex at (0, 0). So moving it up would move the vertex at point (0, 7). The vertex of y is represented by the variable b, therefore b = 7 which further gives us the function:

y' = x^2 + 7

or

g(x) = x^2 + 7

The inequality that represents the numbers of both kinds of CD players that can be sold to reach or exceed the sales target is:

[tex]\[ 72s + 90p \geq 360 \][/tex]

To write an inequality that represents the sales target, we need to consider the profit made from each type of CD player and the total profit required per day.

Let [tex]\( s \)[/tex] represent the number of standard CD players sold, and [tex]\( p \)[/tex] represent the number of portable CD players sold. According to the information given, the store makes a profit of $72 for every standard CD player and $90 for every portable CD player.

The manager's target is to make at least $360 a day from the sales of these CD players. To find out how many of each type of CD player need to be sold to meet this target, we can set up the following inequality:

[tex]\[ 72s + 90p \geq 360 \][/tex]

Here, [tex]\( 72s \)[/tex] represents the total profit from standard CD players, and [tex]\( 90p \)[/tex] represents the total profit from portable CD players. The sum of these two amounts must be greater than or equal to the target profit of $360.

This inequality accounts for all possible combinations of standard and portable CD players that can be sold to meet or exceed the daily profit target. It is important to note that the inequality uses the  greater than or equal to  symbol [tex](\( \geq \))[/tex] because the store wants to make at least $360, and any amount over that is also acceptable.

The decimal number 'six and five hundred and sixteen ten-thousandths' in standard form is 6.0516, which combines the whole number six with the fractional part written as a decimal. Scientific notation is not necessary here since the number is already reasonably simple.

To express the number six and five hundred and sixteen ten-thousandths in standard form, you start by identifying the whole number and the fractional part. The whole number is six, which is straightforward. The fractional part is five hundred and sixteen ten-thousandths, which refers to 516 over 10000. In decimal form, this is written as 0.0516. Combining the whole number with the fractional part gives us the decimal 6.0516. This is the number in standard notation.

Scientific notation simplifies the expression of very large or very small numbers. For example, a large number like 306,000,000 can be written as 3.06 × 108, and a small number like 0.000028 can be expressed as 2.8 × 10-5. However, the number 6.0516 is already concise enough that converting it to scientific notation isn't necessary.
