Problem 34
Answer: [tex]\boldsymbol{n(B) = 3}[/tex]
Reason:
We count the number of items inside set B. In this case there are 3 values, so that is why n(B) = 3
===========================================================
Problem 36
Answer: [tex]\boldsymbol{n(A \cap C) = 1}[/tex]
Reason:
To be able to count the number of items inside set [tex]A \cap C[/tex], we first need to determine what this set looks like. In other words, we need to know the number(s) inside this set.
The upside down U symbol is the intersection symbol. It indicates we want to find what the sets A and C have in common. In this case, it's the value "4" and nothing else. This number is in both set A and set C at the same time. It might help to draw a venn diagram as you see below. I'm ignoring set B entirely since your teacher is not asking about the set in this problem.
We can then say [tex]A \cap C = \{4\}[/tex]
There's only one item inside this set, which is why [tex]n(A \cap C) = 1[/tex]

What is the surface area of this complex figure?
Enter your answer in the box.
The surface area of the complex figure is: 582 ft².
What is the Surface Area of the Complex Figure?Surface area of the complex figure = surface area of the triangular prism + surface area of the rectangular prism - 2(area of the face of the triangular prism that joins with the rectangular prism).
Surface area of the triangular prism = (s1 + s2 + s3)L + bh = (11 + 9 + 9)5 + (11)(7)
Area of the triangular prism = 222 ft²
Surface area of the rectangular prism = 2(wl+hl+hw) = 2·(5·15+8·15+8·5) = 470 ft².
2(area of the face of the triangular prism that joins with the rectangular prism) = 2(lw) = 2(11)(5) = 110 ft²
Surface area of the complex figure = 222 + 470 - 110
Surface area of the complex figure = 582 ft².

Kristina invests a total of $28,500 in two accounts. The first account earned a rate of return of 10% (after a year). However, the second account suffered a 4% loss in the same time period. At the end of one year, the total amount of money gained was $1,310.00. How much was invested into each account?
$_______was invested in the account that gained 10% and
$_______ was invested in the account that lost 4%.
Answer:
$17,500 was invested in the account that gained 10% and
$11,000 was invested in the account that lost 4%
Step-by-step explanation:
Define the variables:
Let x be the money invested in the account that gained 10%.Let y be the money invested in the account that lost 4%.Given information:
$28,500 = total amount invested between the two accounts$1,310.00 = total amount gainedPercentages in decimal form:
10% = 0.14% = 0.04Create a system of equations using the given information and defined variables:
[tex]\begin{cases}x + y = 28500\\0.1x - 0.04y = 1310 \end{cases}[/tex]
Rewrite Equation 1 to make y the subject:
[tex]\implies y=28500-x[/tex]
Substitute into Equation 2 and solve for x:
[tex]\implies 0.1x-0.04(28500-x)=1310[/tex]
[tex]\implies 0.1x-1140+0.04x=1310[/tex]
[tex]\implies 0.14x=2450[/tex]
[tex]\implies x=17500[/tex]
Substitute the found value of x into Equation 1 and solve for y:
[tex]\implies 17500+y=28500[/tex]
[tex]\implies y=11000[/tex]
Conclusion
$17,500 was invested in the account that gained 10% and
$11,000 was invested in the account that lost 4%

Keep the Old Car or Buy a Used Car
Manny is an online student who currently owns an older car that is fully paid for. He drives, on average, 140 miles per week to commute to work. With gas prices currently at $2.87 per gallon, he is considering buying a used, fuel-efficient car, and wants to know if it would be a good financial decision.
The old car Manny owns currently gets 20 miles per gallon for average fuel efficiency. It has been a great vehicle, but with its age, it needs repairs and maintenance that average $740 per year (as long as nothing serious goes wrong).
He is considering buying a newer used car that will cost a total of $5,500 over a three-year loan process. The used car gets 33 miles per gallon and would only require an average of $10 per month for general maintenance. To help make a decision Manny wants to calculate the total costs for each scenario over three years. He decides to use the Quantitative Reasoning Process to do this.
Find the total costs for the newer used car (gas, maintenance/repairs, purchase price) for each scenario over the three years.

F is a right angle, and segment (a)(f), BG, and CH are all parallel. Use this information to explain why ∆AFD ~ ∆BGD ~∆CHD. Support your answer using a postulate or theorem.
Use the diagram to answer each part of the question
By the corresponding angles theorem,
∠AFG, ∠BGD, and ∠CHD are congruent∠BAF, ∠CBG, and ∠DCH are congruentThus, triangles AFD, BGD, and CHD are similar by AA.
Given the figure, triangles AFD, BGD, CGD are similar by Angle-Angle-Angle (AAA) criterion for the similarity.
The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.
In the given question,
∠F = ∠G = ∠H = 90°
Let ∠D = x°
In triangle CHD,
∠H = 90°
∠D = x°
∠C = 180 - 90 - x = (90-x)°
In triangle BGD,
∠G = 90°
∠D = x°
∠B = 180 - 90 - x = (90-x)°
In triangle AFD,
∠F = 90°
∠D = x°
∠A = 180 - 90 - x = (90-x)°
In triangle AFD and BGD and CHD,

32 to 6
48 to 8
Using proportions, the ratio that is not equivalent to the ones shown in the table is given by:
32 to 6.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In the table, the ratios is given as follows:

6) The circumference of a circle is
approximately 37.68 centimeters. What is the radius of the circle to the nearest centimeter?
A. 6 cm
C. 12 cm
B. 8 cm
D. 16 cm
Answer: A, 6 cm
Step-by-step explanation:
Circumference is 2(radius) * pi.
A. 12pi C. 24pi B. 16pi D. 32pi
Assuming pi is roughly 3,
A = 36
C = 72
B = 48
D = 96
A is the closest and if you actually used pi, it would be about 3.14159265 which would make the circumference slightly over 36, which 37.68 is.

what is the next # in this sequence 3, 5, 12, 55, 648
Answer:
35 585
Step-by-step explanation:
Each term is the product of the previous two terms minus the term that is two before
3*5 - 3 = 12
5 x12 - 5 = 55
12 x 55 - 12 = 648
55 * 648 - 55 = 35 585
or each term is term that is two before x (term before -1)
3 (5-1) = 12
5 x (12-1) = 55
12 * (55-1) = 648
55 * ( 648-1) = 35 585
The required next term in the sequence is 35,185.
What is inductive reasoning?Inductive reasoning is defined as, tempting judgments by moving from the details to the fact. It's usually determined with inferential reasoning, where you move from known information to precise conclusions.
here,
Given sequence 3, 5, 12, 55, 648
The given sequence has the following pattern,
3 × 5 - 3 = 12
5 × 12 - 5 = 55
12 × 55 - 12 = 648
55 × 648 - 55 = 35,185
Thus, the required next term in the sequence is 35,185.

Therefore, the altitude on the given diagram is y.
The two internal triangles formed by drawing the altitude are similar to the original triangle. If two triangles are similar, their sides are proportional in length.
