Step-by-step explanation:
To find the volume of this object, find The volume of the cuboid as a whole (ignore the hole as if it's not there) and then remove the volume of the hole (cuboid) from it.
Volume of whole solid = 9 × 6 × 5/4 = 67.5 ft³
For the invisible solid (hole part), you already have width and height, you can find the length too. Length = 9 - (2+3) = 9 - 5 = 4 ft
Volume of invisible solid = 5/4 × 4 × 5/2 = 12.5 ft³
Required volume = 67.5 - 12.5 = 55 ft³

Help me please If you were proving the theorem about the equality of the corresponding angles in this diagram, what would you need to prove first?
A)That the angles are interior.
B)That the angles are vertical.
C)That the angles are all acute.
D)That the angles are congruent.
If you were proving the theorem about the equality of the corresponding angles in this diagram, first you will prove d)That the angles are congruent.
Corresponding angles are generated when a line intersects two parallel lines, resulting in angles that are in the same location with regard to the lines. In this circumstance, all of the angles have measurements that are connected. These are the facts regarding the formed lines and angles.
The parallel lines do not cross. The transversal is the line that connects the parallel lines. Each parallel line has a straight angle, which means that the line measures 180 degrees.
The angles generated by the lines are either equal or supplementary, which indicates that the sum of two angles is 180 degrees. It is necessary that the corresponding angles are congruent angles hence we will check for them first.

According to the given percentage,
The original price of the jacket was $64.
Jeremy surveyed 100 students for his math project.
If the jacket was on sale for 25% off, that means the price Linda paid was equal to 75% of the original price. We can set up an equation to represent this:
0.75x = 48
where x is the original price of the jacket. To solve for x, we divide both sides by 0.75:
x = 48 / 0.75
x = 64
If 18% of the students surveyed selected hamburgers, that means the remaining 82% did not select hamburgers. We can represent this with an equation:
0.18x + 0.82x = x
where x is the total number of students surveyed. The left-hand side of the equation represents the number of students who selected hamburgers (0.18x) plus the number who did not (0.82x), which must equal the total number surveyed (x).
Simplifying the equation, we get:
x = 100x / 100
Dividing both sides by 100, we get:
x = 1 / 0.01

You deposit $5000 in an account earning 3% interest compounded monthly. How much will you have in the
account in 10 years?
Compound interest, also known as interest on principal and interest, is the practice of adding interest towards the principal amount of a loan or deposit.
How does compound interest work?The yearly interest rate is raised to the amount of compounded periods minus one, and the starting principal amount is multiplied by both of these factors. The resulting value is subsequently deducted from the loan's entire original amount.
P = $5,000 for the principle (initial investment)
Annual interest rate equals 0.03 (as a decimal)
t = the number of years (10).
Euler's number is e = 2.718281.
A = the sum at time t, or A = P·(e(rt))
[tex]\sf A = 5000(2.718281^{(0.03\times10)})[/tex]

Option - B is correct that is the measure of angles A is 31° when ∠A and ∠B are complementary angles.
Given that,
The part of your question is missing that is ∠A and ∠B are complementary angles with ∠A = (2x - 3)° and ∠B = (3x + 8)°.
We have to measure the angle A.
We know that,
Complementary angles means sum of the angles is equal to 90°
That means,
∠A + ∠B = 90°
2x -3 + 3x + 8 = 90°
5x + 5 = 90°
5x = 90 - 5
5x = 85
x = [tex]\frac{85}{5}[/tex]
x = 17°
Now by substituting
∠A = 2x -3
∠A = 2(17) -3
∠A = 34 - 3
∠A = 31
Therefore, The measure of angles A is 31°.

Step-by-step explanation:
Let us say that the number is x
Now , According to the question ,
let us start by considering the L.H.S first i.e. three times a number increased by 12 i.e. 3^x+12 -------(1)
Now , consider R.H.S i.e. Five times the same number decreased by 18 i.e.
5^x-18-------------(2)
Now we are given that both the numbers are equal so here we equate eqn (1) and eqn (2)
⇒ 3x + 12 = 5x - 18
⇒ 12 +18 = 5x - 3x
⇒ 30 = 2x
⇒ 2x = 30
⇒ x = 30/2
⇒ x = 15
∴ Hence 15 is the required number

sebastioan swam laps every day in the community swimming pool. he swam 45 minutes each day, 5 days each week, for 12 weeks. In that time, he swam 1,800 laps. What was his average rate in laps per hour?
The solution is : Sebastian swam 40laps in one hour in average.
Here, we have,
Sebastian swam 45minutes per day.
If she swam 5days a week, this is equivalent to Sebastian swimming 60days in 12weeks.
If Sebastian swam 45minutes in a day, she must have swam for (45×60)minutes in 60days which is equivalent to 2700minutes
Converting 2700minutes to hours;
60minutes = 1hour
2700minutes = x
x = 2700/60
x = 45hours
Since sebastian swam 1800laps in that 12weeks in 45hours, her average rate lap per hour can be calculated thus;
1800laps = 45hours
X laps = 1hour
30 × X = 1800
X = 1800/45
X = 40laps
This shows that Sebastian swam 40laps in one hour in average.

A survey in 2021 found that 68% of students prefer to take some of their courses fully online. If three students are selected at random, find the probability that all three prefer to take some of their courses fully online.
Will give brainly! Thank you!
Answer:
ΑΠSШЕЯ®
Step-by-step explanation:
The probability that all three students prefer to take some of their courses fully online can be found by multiplying the probabilities of each event together. Since each student has a 68% chance of preferring fully online courses, the probability that the first student prefers fully online courses is 0.68, the probability that the second student prefers fully online courses given that the first student does is also 0.68, and the probability that the third student prefers fully online courses given that the first two students do is also 0.68. Therefore, the probability that all three students prefer to take some of their courses fully online is 0.68 x 0.68 x 0.68 = 0.314. The probability is approximately 0.314 or 31.4%.
a person is 21 years old and plans on retiring at age 55. This person is going to invest $75 each month into an ira
For the person to reach a retirement savings goal (future value) of $100,000 at age 55, they need to invest an additional $81 monthly.
Determining the additional monthly investment:
The additional monthly investment is computed as the difference between the expected monthly deposits and the intended monthly deposits.
The expected monthly deposits (periodic payments) are determined using an online finance calculator.
Current age = 21 years old
Retirement age = 55 years old
Investment period = 34 years (55 - 21)
N (of periods) = 408 months (34 years x 12)
I/Y (Interest per year) = 2.5%
Present Value = $0
FV (Future Value) = $100,000
Periodic Payments (PMT) = $155.75
Sum of all periodic payments = $63,546
Total Interest = $36,454
Intended monthly deposits = $75
Additional monthly deposits required = $80.75 ($155.75 - $75) = $81
Thus, the investor needs to invest an additional $81 to the $75 monthly deposits to reach a future value of $100,000 in 34 years, compounded at 2.5% monthly.

Determine how much you will pay in property tax for the year. $
The monthly property tax bill will be $2,670.42.
To determine the property tax, we need to first find the assessed value of the condominium:
Assessed value = 29% of market valueMarket value = $135,000Assessed value = 0.29 x $135,000 = $39,150Next, we need to find the property tax rate:
Mill rate = 81.85%o = 0.8185
To find the annual property tax, we multiply the assessed value by the mill rate:
Annual property tax = Assessed value x Mill rateAnnual property tax = $39,150 x 0.8185Annual property tax = $32,045.03Finally, to find the monthly property tax, we divide the annual property tax by 12:
Monthly property tax = Annual property tax / 12Monthly property tax = $32,045.03 / 12Monthly property tax = $2,670.42 (rounded to the nearest cent)Therefore, the monthly property tax bill will be $2,670.42.
