For problem 3, the solution is x = 105For problem 4, the solution is x = 75==========================================================
Explanation for problem 3
For any convex polygon, the sum of the interior angles is equal to 180(n-2), where n is the number of sides.
In this case, we have a hexagon with 6 sides, so n = 6
The interior angles for the hexagon add to 180(n-2) = 180(6-2) = 720
We'll add the given angles and set that sum equal to 720, then solve for x.
135+110+125+120+125+x = 720
615+x = 720
x = 720-615
x = 105
-------------------------------------
Explanation for problem 4
We'll use the same formula and idea as the previous problem.
This time we have n = 4 sides. This is a quadrilateral.
The interior angles add to 180(n-2) = 180*(4-2) = 360 degrees
So,
x+90+80+115 = 360
x+285 = 360
x = 360-285
x = 75
Note: the square angle marker represents 90 degrees

Which number in the set {6, 12, 18, 36} satisfies the equation 6x - 18 = 54?
Answers
Answer:
Here we can go for trial and error,
Taking x=6
So equation will be 6*6-18 which gives 18
and is not equal to 54
So it's, not 6
Trying 12
6*12-18
Which is 54 and so correct answer is x=12

Step-by-step explanation:
I think it would probably just be 52 because if you replace (x) with (2) and simplify the equation, you get 52.

which number is the same as for the power of negative 1 * 2 ^ 8 / 4 ^ -2
A) -2
B) 1/5
C) 2
D) 32
E) 512
Answers
Answer: D) 32
Step-by-step explanation:
To solve the expression (4 to the negative power of 1)(2 to the 3rd power divided by 4 to the negative power of 2), we can follow these steps:
Step 1: Simplify 4 to the negative power of 1
4 to the negative power of 1 can be written as 1/4 to the positive power of 1, so the expression becomes: (1/4)(2 to the 3rd power divided by 4 to the negative power of 2)
Step 2: Simplify the division of powers of 4
When dividing powers with the same base (in this case, 4), we can subtract the exponents. So, 4 to the negative power of 2 is the same as 1/4 to the power of 2, which equals 1/16. The expression now becomes: (1/4)(2 to the 3rd power divided by 1/16)
Step 3: Simplify 2 to the 3rd power 2 to the 3rd power is 2x2x2, which equals 8. The expression now becomes: (1/4)(8 divided by 1/16)
Step 4: Simplify the division
Dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the expression as: (1/4)(8 x 16)
Step 5: Multiply 8 x 16 equals 128, so the expression simplifies to: (1/4)(128)
Step 6: Simplify the final expression
Multiplying 1/4 by 128 gives us 32. Therefore, the final answer is: 32

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land does the farmer own?
Write your answer as a mixed number in simplest form.
Answers
Answer:
This is simple multiplication of fractions, not too bad!
we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.
To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.
Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.
Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.
(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.

The structure is shaped as a right triangle.
Use the Pythagorean theorem to solve for 'c' or the hypotenuse.
[tex]a^2+b^2=c^2\\\\8^2+15^2=c^2\\\\64+225=c^2\\\\289=c^2\\\\\sqrt{289} =\sqrt{c^2}\\\\17, -17 = c\\\\\text{Disregard negative value.}\\\\\boxed{17=c}[/tex]
The hypotenuse should be 17 feet.
Hope this helps!
Answer: 17 ft.
Step-by-step explanation: By using the pythagorean theorem (a^2 + b^2 = c^2) for right triangles, you should be left with the given equation after plugging in the values of the legs:
8^2 + 15^2 = c^2
Now simplify the squares
64 + 225 = 289 (c^2)
Now to find the exact value of the hypotenuse (c), square root the value of c^2.
√289 = 17
The hypotenuse of the triangles is 17 ft.
