The product in simplest form is (x - 4)

Solution:

Given expression is:

[tex]\frac{8}{2x+8} \times \frac{x^2-16}{4}[/tex]

We have to find the product in simplest form

In the given expression,

2x + 8 = 2(x+ 4)

We know that,

[tex]a^2-b^2=(a+b)(a-b)[/tex]

Therefore,

[tex]x^2-16 = x^2-4^2 =(x+4)(x-4)[/tex]

Substitute these in given expression

[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4}[/tex]

Cancel the common factors,

[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4} = x - 4[/tex]

Thus the product in simplest form is (x - 4)

Answer:

A sphere.

Step-by-step explanation:

The sun is a sphere.

The best geometric shape to describe the Sun is a sphere, as it appears as a circular disc in the sky and fits with observational data and theoretical models of its structure and the Earth's orbit around it.

When considering the geometric shape that best describes the Sun, we assess its physical appearance and symmetry. The Sun is often depicted in diagrams as having a perfectly round, spherical shape, which aligns with our observations, as it appears as a circular disk in the sky. A sphere is a three-dimensional object where every point on the surface is the same distance from the center, which closely matches the Sun's observed shape. Unlike a triangular prism, cube or cylinder, a sphere has no edges, vertices, or faces, which makes it the best match for the Sun's shape.

Moreover, observations about the Sun, like those represented in figures discussing its structure as well as the Earth's orbit around the Sun, support the description of the Sun as being spherical. The orbit of the Earth itself is very close to a circle, which assumes central body - the Sun - of spherical form to exert a uniform gravitational pull. Additionally, the celestial sphere concept, although now known to be an incorrect model for the universe, also envisions stars, including our Sun, as points on a vast imaginary sphere, once more alluding to the spherical structure of these celestial bodies.

The measure of angle 5 is 75°.

Step-by-step explanation:

Properties of intersecting lines :

step 1 :

From the figure, the angle (-9x-12) and angle (6x+183) are vertically opposite and are equal.

-9x-12 = 6x+183

⇒ -9x-6x = 183+12

⇒ -15x = 195

⇒ x = -(195/15) = -13

step 2 :

Substitute x= -13 in the angle (-9x-12)

⇒ (-9x-12) = -9(-13)-12

⇒ 117 - 12 = 105°

step 3 :

The measure of angle in a line is supplementary (180°).

Let angle 5 be unknown value "a".

Then, angle (-9x-12) + angle a = 180°

⇒ 105° + a = 180°

⇒ a = 180 - 105

⇒ a = 75°

∴  The measure of angle 5 is 75°

Step-by-step explanation:

(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)​

We need to combine like terms, take care the exponents of r and s

(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)​

multiply the second parenthesis by -1

= 8r⁶s³-9r⁵s⁴+3r⁴s⁵-2r⁴s⁵+5r³s⁶+4r⁵s⁴

= 8r⁶s³ + (-9r⁵s⁴ + 4r⁵s⁴) + (3r⁴s⁵-2r⁴s⁵) + 5r³s⁶

= 8r⁶s³ - 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶

Answer:

z = 73

x = 15

Step-by-step explanation:

Since z and (5x +32) share a straight line, adding them would equal 180.

(5x+32) + z = 180

Since z is 73, we can replace z

(5x + 32)  + 73 = 180

(5x + 32) = 107

(5x) = 75

x = 15

The profit from producing and selling x laser printers is given by the equation P(x) = 125x - 2300000.

The question is about the calculation of profit in a business scenario. The calculation of profit involves finding the difference between the cost of production and the revenue obtained from selling the products. In this case, the cost function C(x) = 325x + 2300000 defines the cost of producing x laser printers. Each printer is sold for $450, which means the revenue function R(x) can be represented as R(x) = 450x.

To find the profit, we subtract the cost from the revenue. This gives us the profit function P(x) = R(x) - C(x) = 450x - (325x + 2300000). Simplifying this, we get P(x) = 125x - 2300000. This equation tells us the profit made from producing and selling x laser printers.

Probability of getting tails on the first flip: 1/2 (because it's one of two possible outcomes).

Probability of getting tails on two consecutive flips: 1/4 (because it's one out of four possible outcomes- tails tails, tails heads, heads tails, heads heads)

A simpler way of thinking about it is 1/2*1/2, because you already have 1/2 for getting tails the first time, and if getting tails the second time were an independent event then the probability would be 1/3, but since it's getting tails twice you multiply the probabilities.

Either way, the answer is 1/4 (or 25%)

If you flip a coin twice the probability that you get tails on the first flip and tails on the second flip is 1/4.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that you flip a coin twice, the probability getting tails on the first flip we have to find the probability that you get tails on the first flip and tails on the second flip.

The probability of getting tails on the first flip is

P(T) = 1/2

When two coins get flipped the total possible outcomes are,

(T, H)(T,T)(H,H)(H,T)

Probability of getting tails on two consecutive flips,

Answer:

Final answer:

The inequality to determine the number of hot dogs Jeff could have bought is 3h + 2 ≤ 14, representing the cost of hot dogs and the bottle of water not exceeding the total amount of $14.

Explanation:

To find h, the number of hot dogs that Jeff could have bought, we can write an inequality statement based on the maximum amount Jeff can spend and the cost of the hot dogs and water. Jeff bought one bottle of water for $2 and some hot dogs for $3 each. Given that he did not spend more than $14 on everything, the inequality to represent this scenario can be written as:

Cost of water + Cost of hot dogs ≤ Total amount Jeff can spend

2 + 3h ≤ 14

This inequality suggests that when we multiply the number of hot dogs Jeff bought (h) by $3 and add the cost of the water ($2), it should not exceed $14. So the inequality demonstrating the number of hot dogs Jeff could have bought without spending more than $14, including the water, is 3h + 2 ≤ 14.

The actual rate of the mortgage is 5.27%.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Since, we're taking two mortgages for a total of $100,000 for 30 years,

Now, we can find the actual rate of the mortgage by finding the weighted average of the two rates.

Hence, The weights in this case will be the proportion of loan taken at each rate;

We have

Rates       Weights      Rates  × Weights

4.15           0.80           4.15 x 0.80 = 3.32

9.75           0.20          9.75 x 0.20 = 1.95

Hence, The actual rate of the mortgage is,

⇒ 3.32 + 1.95

because he 6 in 4/6 cant go into 16 and 16 from 12/16 c 36 so that is why the answer is 12/16

After simplifying each fraction to its lowest terms, it's clear that 12/16, which simplifies to 3/4, is not equivalent to the others since they all simplify to 2/3.

The question asks which of the following fractions is not equivalent to the others: 24/36, 8/12, 12/16, 4/6. To determine this, we need to simplify these fractions to their lowest terms.

24/36 simplifies to 2/3, by dividing both numerator and denominator by 12.

8/12 simplifies to 2/3, by dividing both numerator and denominator by 4.

12/16 simplifies to 3/4, by dividing both numerator and denominator by 4.

4/6 simplifies to 2/3, by dividing both numerator and denominator by 2.

Therefore, the fraction 12/16 is not equivalent to the others since it simplifies to 3/4, while the others simplify to 2/3.
