Hello

To expand this, we will multiply the value outside the bracket with the one inside the bracket.

The answer to this question is -8x +17

value outside the bracket with the one inside the bracket.

The weight of Brad is 70 lb and the weight of Sean is 150 lb now.

According to the question,

We have the following information:

Sean weighs 10 lb more than twice Brad’s weight. If Brad gains 10 lb, together they will weigh 230 lb.

Now, let's take Brad's weight to be x lb.

So, we have:

Sean's weight = (10+2x) lb

Now, when Brad gains 10 lb, we have the following expression:

(x+10)+(10+2x) = 230

3x+20 = 230

3x = 230-20

3x = 210

x= 210/3

x = 70 lb

Now, Sean's weight = (10+2x) lb

Putting the value of x:

Sean's weight = 10+2*70

Sean's weight = 10+140

Sean's weight = 150 lb

Hence, the weight of Brad is 70 lb and the weight of Sean is 150 lb now.

The equation of the line that passes through point (-5,3) and perpendicular to y=5x-3 is y = -(1/5)x + 2.

The point-slope formula is expressed as

y - y₁ = m( x - x₁ )

Given the data in the question;

First, determine the slope of the initial line using the slope intercept-form. y = mx + b

y = 5x - 3 compared with the slope intercept form,

Slope m = 5

Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.

Hence, slope of the perpendicular line is;

Slope m = -1/5

Next, find the equation of the perpendicular line, by using the point slope formula.

y - y₁ = m( x - x₁ )

Plug in the slope m ( -1/5 ) and point (-5,3).

y - y₁ = m( x - x₁ )

y - 3 = -1/5( x - (-5) )

y - 3 = -1/5( x + 5 )

y - 3 = -1/5(x) -5/5

y - 3 = -1/5(x) - 1

y = -1/5(x) - 1 + 3

y = -(1/5)x + 2

Therefore, the equation of the perpendicular line is y = -(1/5)x + 2.

We are given a rectangle with the following dimensions;

Also, placed inside the large rectangle, is a smaller shaded rectangle which has the dimensions;

The ratio of both figures can be expressed as follows;

Substituting for the values of both figures, we now have;

The number of feet from the tent pole to the rope along the ground will be 12 Feet.

Let:

        RQ = x

According to Pythagoras Theorem:

[tex]Hypotenuse^{2} = Perpendicular^{2} + Base^{2} \\PQ^{2} = PR^{2} + RQ^{2} \\15^{2} = 9^{2} + x^{2} \\225 = 81 + x^{2} \\x^{2} = 225 - 81\\x^{2} = 144\\x = 12[/tex]

Therefore, the number of feet from the tent pole to the rope along the ground will be 12 Feet.

Step-by-step explanation:

To answer this question you need to understand what GCF is

GCF is Greatest Common Factor

GCF is the highest number that divides exactly into two or more numbers.

The expression is 16x + 28

The highest number that can divide 16 and 28 is 4

Dividing 16x + 28 gives => 16x/4 + 28/4 => 4x + 7

So the factored expression is

4(4x + 7)

The probability that the mean daily revenue for the next 30 days will be less than $7000 IS 0.7333

Standard deviation of the sample is equal to the population's Standard Deviation divided by the square root of the sample's item count.

Standard Deviation of the sample = [tex]1200/\sqrt{30} = 219.09[/tex]

SD of the sample is equal to the population's Standard Deviation divided by the square root of the sample's item count.

To reach a result of 300, divide 7500 by the mean of 7200. 300 divided by the sample's SD (219.09) yields a result of 1.37. A z-table search for +1.37 returns a result of 0.9147. Accordingly, there is a 0.9147 percent chance that the average daily revenue over the following 30 days will be less than $7500.

To get a result of -200, divide 7000 by the mean of 7200. Divide -200 by the sample's standard deviation (219.09), and you'll get -0.91. search for -0.91 in a z-table receive a score of 0.1814. The likelihood that the mean daily revenue for the following 30 days would be less than $7000 is therefore 0.1814.

Simply subtract the likelihood that the mean daily revenue is less than $7000 (0.1814) from the likelihood that the mean daily revenue is less than $7500 (0.9147) to arrive at the probability that the mean daily revenue for the upcoming 30 days will be between $7000 and $7500. This yields a result of 0.7333.

There is a 73.33% chance that the average daily income over the following 30 days will be less than $7000.

The exponent of x in the expression (x¹⁰)³⁺⁵ is 6.

Exponent rules, commonly referred to as the "laws of exponents" or "properties of exponents," facilitate the task of simplifying exponent-based statements. These rules can help simplify formulas with exponents that are decimals, fractions, irrational numbers, or negative integers.

The mathematical process known as an exponent often indicates the power of a variable.

As of right now, we are aware that under the scenario of

[tex](x^{a})^{b} = x^{ab}[/tex]

Therefore, solve the power by multiplying 10 by 3/5, and we get
