Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

80/100*72=57.6

As it’s 80% we need to divide 80/100 and they said of 72 so we have to then multiply with 72

The product of the two expressions (x - 2)(x + 2) gives x² - 4

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the expression (x - 2)(x + 2):

Multiplying the two expressions gives:

x² + 2x - 2x - 4

This gives:

x² - 4

The product of the two expressions (x - 2)(x + 2) gives x² - 4

Use trigonometry to find L.

Tangent = opposite over adjacent on any right triangle.

tan(L) = 18/23

Take the inverse on both sides.

arctan(tan(L)) = arctan(18/23)

L = 38.0470425318

L = 38.05°

Done.

Answer:

There are 30 temporary employees

Step-by-step explanation:

To find x% of quantity A, multiply x% by A after change x% to the normal number by divide it by 100 ⇒ (x ÷ 100) × A

Let us use this rule to solve the question

∵ The local water slides have 100 employees

∵ 30% of them are temporary

∴ The number of temporary employees = 30% × 100

∵ 30% = 30 ÷ 100 = 0.30

∴ The number of temporary employees = 0.30 × 100

∴ The number of temporary employees = 30

∴ There are 30 temporary employees

Step-by-step explanation:

each line had points on it. what you want to do is go to the bottom point. then go up until you hit the line where the other point is. then go to the side to where the other line is. make sure you're counting the whole time. if it can be simplified (ex: 2/4), simplify it. if the line is pointing to the left, it is negative. remember, rise over run, if pointing left it's negative, and draw a triangle from the points (which i didnt say but it works).

Answer:

[tex]\boxed {x < -4}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]7(x + 3) < 5x + 13[/tex]

Use Distributive Property:

[tex]7(x + 3) < 5x + 13[/tex]

[tex]7x + 21 < 5x + 13[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]7x[/tex]:

[tex]7x + 21 - 5x < 5x - 5x + 13[/tex]

[tex]2x + 21 < 13[/tex]

Subtract both sides by [tex]21[/tex]:

[tex]2x + 21 - 21 < 13 - 21[/tex]

[tex]2x < -8[/tex]

Divide both side by [tex]2x[/tex]

[tex]\frac{2x}{2} < \frac{-8}{2}[/tex]

[tex]\boxed {x < -4}[/tex]

Answer:

y = [tex]\frac{-2x}{3}[/tex]

Step-by-step explanation:

Distribute 5 to 2x and 3y by multiplying each by 5

10x + 15y

Isolate y to one side of the equation

15y=-10x

Divide each side by 15

y = [tex]\frac{-2x}{3}[/tex]

Answer:

5(2x + 3y) = 10x + 15y

Step-by-step explanation:

There is one particular way to find an equivalent expression which I am assuming is what the problem is looking for. When given a factored expression in the form of a binomial (two terms), by creating an equivilent expression, you can distribute the binomial inside the parenthesis factored by the coefficient 5. So 5(2x + 3y) = 5(2x) + 5(3y) = 10x + 15y.

5 is also the greatest common factor of 10x + 15y which is why this expression simplifies down to the equivilent expression 5(2x + 3y).

10x + 15y as a GCF is really the GCF of 10 and 15. What you do is individually split each number into all its possible factors(set of whole numbers that multiply to that number), and then find the factor that they both share.

For example, 10 has factors of 5, 2, 1, 10. And 15 has factors of 15, 1, 5, 3.

Notice how 5 appears in both.

Answer:

0.9451

Step-by-step explanation:

Remaining question? "How is the result affected by the additional information that the survey subjects volunteered to​respond?"

Probability that at least 1 user is more careful about personal information when using a public Wi-Fi hot spot is:

P(X≥1) = 1 − P(X<1)

= 1 − P(X=0)

= 1 - [(3,0) (0.62)^0 (1-0.62)^3-0

= 1 - 0.054872

= 0.945128

= 0.9451

Thus, the probability that among three randomly selected Internet users; at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.9451

Answer: Each apple would cost $0.75.

Step-by-step explanation: If each juice is $1.75, then 2 of them equal $3.5. Subtract this from $9.50 to get 6 dollars remaining. We know now we can buy 8 apples from the remaining 6 dollars. So from this, divide 6 by 8, you get $0.75.

Answer:

18 will be the number of sides.

Step-by-step explanation:

As we know that the sum of exterior angles of a polygon is 360°.

The formula is:

As each exterior angle of a regular polygon is 20°.

so putting the value exterior angle 20° in the formula

The exterior angle of a polygon = 360 ÷ number of sides

                                               20  = 360 ÷ number of sides

                                               20  = 360/number of sides

so the number of sides will be:

                         number of sides = 360/20

                                                     = 18

Therefore, 18 will be the number of sides.
