Answer:
How do you find the angle of a right triangle with 3 sides?
Step-by-step explanation:
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
Step 4 Find the angle from your calculator using cos-1 of 0.8333:

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:
The exterior angle of a polygon = 360 ÷ number of sidesAs 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.

7( x+3 ) < 5x + 13
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]

The local water slides have 100 employees, of which 30% are temporary. How many temporary employees are there?
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

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°

Based on a poll 62% of internet users are more careful about personal information when using a public wifi hotspot. What is the probability that amoung three randomly selected internet users at least one is more careful about personal information when using pubblic wifi hotspot?
Answer:
0.9451
Step-by-step explanation:
Remaining question? "How is the result affected by the additional information that the survey subjects volunteered torespond?"
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
It takes 3 hours to cook an 8-pound turkey. How long would it take to cook a turkey that is 14 pounds? Round to the nearest tenth.
Answer:
5.3 hours
Step-by-step explanation:
Given:
3 hours = 8lbs. turkey
?? hours = 14lbs. turkey
Do proportions:
[tex]\frac{3}{8}[/tex] = [tex]\frac{x}{14}[/tex] <-- Cross Multiply
42 = 8x <-- Solve for x
x = 5.25
Round to the nearest tenth:
x = 5.3 hours
You are Buying snacks. you buy 8 apples and 2 juices. the juice costs $1.75 each. The total cost is 9.50. How much is 1 apple?
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.
John claims the following two expressions are equivalent.

John's work in determining an expression equivalent to the first expression is shown below.
- 2/5y - 3)
= (-2x5y) - (-2x - 3)
= - 10y-6
Which statement explains why John's claim is incorrect?
He should have subtracted (-2 * 3) resulting in the expression–10y + 6.
He should have only multiplied 3 by -2 resulting in the expression 5y - 6.
He should have only multiplied Sy by -2 resulting in the expression-10y - 3.
He should have only multiplied 3 by -2 and subtracted (-2 * 3) resulting in the expression 5y + 6.
А.
В.
С.
D
Answer:
the answer is B. He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Step-by-step explanation:
In the given expressions, the reason for John's claim being incorrect would be:
B). He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Given,
The two expressions i.e. [tex](-215y - 3) = - 10y - 6[/tex]The mistake that John makes is that he multiplies the entire equation by -2 as shown in [tex]= (-2x5y) - (-2x - 3)[/tex] which makes it incorrect.In order to rectify this mistake, only 3 was suppossed to be multiplied by -2 so that the outcome comes out as [tex]5y - 6[/tex].Thus, option B is the correct answer.

i kinda need this awnser asap also its for a flip grid so not to advanced
I WILL GIVE BRAINLIEST
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.

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).
