they appear answered but their not.
1) The equivalent fraction is 27/8, so the correct option is A.
2) The value of the exponent in the right side must be y = 2, the correct option is C.
How to find an equivalent fraction?1) First we want to find an equivalent fraction to (2/3)^(-3)
Remember that a negative exponent means that we nee to take te inverse, we can write:
(2/3)^(-3) = (3/2)^3
Now we can just distribute the exponent along the numerator and denominator.
(3/2)^3 = (3^3)/(2^3) = 27/8
The correct option is A.
2) How to find the value of y?
Here we have the equation:
(3^3)^2/9^2 = 3^y
If we move the denominator to the right side, we can write:
(3^3)^2 = 9^2*3^y
Now, remember that:
9 = 3^2
Then we can write the right side as:
(9^2)*3^y = (3^2)^2*3^y = 3^(2*2)*3^y = 3^(4 + y)
Replacing that in the original equation we get:
(3^3)^2 = 3^(4 + y)
The exponent in the left side can be rewritten as:
(3^3)^2 = 3^(3*2) = 3^6
The the equation becomes:
3^6 = 3^(y + 4)
This is only true if:
6 = y + 4
6 - 4 =y
2 = y
The correct option is C.

Find the measure of each marked angle. Assume the lines are parallel
The value of x is 33
What other external angles are there?
The alternate exterior angle theorem states that when two parallel lines cross, the exterior angles formed on either side of the transversal are equal. The distance between two intersecting lines or surfaces at or around their meeting point is referred to as the angle.
Since (2x - 30°) and (x+3)° are alternate exterior angles, they will be equivalent to one another.
(2x - 30)° = (x+3)°
Separate all similar phrases, then determine the value of x:
(2x - 30)° = (x+3)°
2x - x = 33 + 3
x = 33
Consequently, x will have the value of 33.

A country has a goal to build 12,000 bus stop shelters in 48 months if the country builds 215+ shelters each month will it reach at school explain one way to estimate the answer
If it reaches 250 bus stop shelters per month, then only the country can achieve their goal of 12000 bus stop shelters in 48 months.
Given,
The number of bus stop shelters a Country should built = 12,000
Time period for achieving the goal = 48 months
The average bus stop shelters the country can build in a month = more than 215
We have to explain that if they follow the above given format, will they achieve the goal in 48 months.
We can find it by using division operation;
Lets see;
Number of bus stop shelters they should build in one month = 12000/48 = 250

Triangle ABC has the following angle measures:
mLA = (x + 6)°, mzB = (3x - 15)°, mzC = (5x +36)°
What is m/C?
The value of ∠C: 121°
What is Triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane.
Given this,
There is an ABC triangle.
m∠A = (x + 6)°
m∠B = (3x - 15)°
m∠C = (5x + 36)°
The size of C must be determined.
Having said that,
A triangle's total number of angles equals 180 degrees.
As a result, we can say,
∠(A) + ∠(B) + ∠(C) = 180
(x + 6)° + (3x - 15)° + (5x + 36)° = 180°
(x + 3x + 5x) + (6 - 15 + 36) = 180°
9x + 27 = 180°.
9x = 180 - 27
9x = 153 degrees
x = 153/9 degrees
17 = x.
Hence,
The ∠C is expressed as
∠C = 5x + 36
= 5*17 + 36
= 85 + 36
∠C = 121.
Thus, ∠C = 121.

3 $30,000 $19,200 $10,800 $4,320 $23,520 $6,480
The double-declining-balance approach is what?
The double-declining-balance method is one of the depreciation techniques in use, however it adds additional costs in the first years of an asset's life.
In this depreciation method, the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2, is twice.
At the conclusion of each year, the leftover balance for the depreciation charge is adjusted using the double rate.
The difference between the closing balance from the previous year and the residual value is used to determine the depreciation charge for the most recent year.
Auto = $30,000
Estimated useful life = 5 years
Residual = $800
Depreciable amount = $30,000 - $800 = 29,200
Straight-line depreciation rate = 100/5 = 20%
Double-declining depreciation rate =20% x 2 = 40%
Depreciation Expense:
1st year = 30,000 x 40/100 = 12,000
2nd year = 18,000 x 40/100 = 7,200
3rd year = 10,800 x 40/100 = 4,320
4th year = 6,480 x 40/100 = 2,592

Opera tickets sold for $7.50 on the main floor and $5 in the balcony. The total revenue was $3250, and there
were 100 more main floor tickets sold than balcony tickets. Find the number of tickets sold.
Answer
500 tickets were sold
Step-by-step explanation:
Since 100 main floor tickets were sold, and each cost $7.50, we multiply it by 100 which equals $750, then since revenue was $3250, we do $3250 - $750 = $2500. Now that we got the extra tickets taken out of the way, time to find the rest. First, we add the prices of both tickets together, $7.50 + $5 = $12.50, then divide it by the remaining revenue, $2500 divided by $12.50 = 200 tickets, so 200 of each ticket were sold, + 100 main floor tickets. So now we do 300 main floor tickets + 200 balcony tickets, which is 500 tickets in total. Maybe you didn't read this but that's alright :)
