Question 6 of 10
True or false? If you took a true "if-then' statement and reversed the clauses,
the new statement would also be true.
OA. True
OB.
False
The statement that "if you took a true "if-then' statement and reversed the clauses, the new statement would also be true" is False.
Why is this false ?By reversing the clauses within an accurate "if-then", one will manifest a new statement known as the "converse" of the initial formula. Though, it is not inevidably true.
For instance, if the original expression was "If it rains, then the ground gets wet", its converse is "If the ground gets wet, then it rains". Unfortunately, that specific converse has the potential to be incorrect since there are several other methodologies from which the land can gain moisture beside rain (e.g. sprinkler system, someone unintentionally pouring water, etc.).

C (Wait for another defendant, check with him and write this answer)
Triangle ABC is being enlarged using a scale factor of and centre (2,9) to
give triangle A'B'C'.
a) What are the coordinates of the vertex C'?
b) What is the length of the side A’B’
a) The coordinates of the vertex C' are C'(x, y) = (5, 5).
b) The length of the side A'B' is equal to 4.
In this problem we find the case of a right triangle, whose image must be found by a kind of rigid transformation known as dilation. The dilation formula for a vertex is introduced below:
P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]
Where:
k - Dilation factor
O(x, y) - Center of dilation
P(x, y) - Original vertex
P'(x, y) - Resulting vertex
And the dilation formula for a formula is:
L' = k · L
Where:
L - Original length.
L' - Resulting length.
Please notice that side lengths can be found by Pythagorean theorem.
we know that O(x, y) = (2, 9), k = 1 / 2, A(x, y) = (6, 7), B(x, y) = (10, 7) and C(x, y) = (6, 1), then the resulting vertices and sides are:
C'(x, y) = (2, 9) + (1 / 2) · [(6, 1) - (0, 9)]
C'(x, y) = (2, 9) + (1 / 2) · (6, - 8)
C'(x, y) = (2, 9) + (3, - 4)
C'(x, y) = (5, 5)
And the length of the side A'B' is:
AB = 8
A'B' = (1 / 2) · AB
A'B' = 4

mrs. gordon bought a stove which cost $850. no down payment was required. mrs. gordon has to pay $160 for the next six months. what is the average amount she pays in interest each month?
Answer:
the average amount Mrs. Gordon pays in interest each month, we need to determine the total interest paid over the six-month period and divide it by the number of months.
The total interest paid can be found by subtracting the cost of the stove from the total amount paid over six months:
Total interest paid = Total amount paid - Cost of the stove
The total amount paid over six months is calculated by adding the monthly payments:
Total amount paid = $160/month * 6 months
Let's perform the calculations:
Total amount paid = $160/month * 6 months = $960
Total interest paid = Total amount paid - Cost of the stove
= $960 - $850
= $110
Now, to find the average amount Mrs. Gordon pays in interest each month, we divide the total interest paid by the number of months:
The average amount paid in interest each month = Total interest paid / Number of months
= $110 / 6 months
≈ $18.33
Therefore, Mrs. Gordon pays an average of approximately $18.33 in interest each month.
Principle amount is 22,000. Interest rate is 4.5%.
1. Determine interest earned each year.
2. Write a recurrence relation to model the value of investment from year to year. Let Sn be the value after n years.
3. Determine value of interest after 5 years.
Answer:
1. $990
2. Sn = Sn-1 + (r/100) * Sn-1
3. $27,037.44
Step-by-step explanation:
1. The interest earned each year can be calculated using the simple interest formula:
Simple Interest = (Principal * Rate * Time) / 100
Here, Principal = $22,000, Rate = 4.5%, and Time = 1 year
So, the interest earned each year would be:
= (22,000 * 4.5 * 1) / 100
= $990
Therefore, the interest earned each year would be $990.
2. The recurrence relation to model the value of investment from year to year is:
Sn = Sn-1 + (r/100) * Sn-1
where Sn represents the value of the investment after n years, Sn-1 represents the value after n-1 years, and r represents the annual interest rate.
Using this recurrence relation, we can calculate the value of the investment for different years:
- S1 = 22,000 + 990 = 22,990
- S2 = 22,990 + (4.5/100) * 22,990 = 24,026.55
- S3 = 24,026.55 + (4.5/100) * 24,026.55 = 25,103.46
And so on...
3. To determine the value of the investment after 5 years, we can simply substitute n = 5 in the recurrence relation:
S5 = S4 + (r/100) * S4
= S3 + (r/100) * S3 + (r/100) * S3
= S2 + (r/100) * S2 + (r/100) * S2 + (r/100) * S2
= S1 + (r/100) * S1 + (r/100) * S1 + (r/100) * S1 + (r/100) * S1
Substituting values from previous calculations:
S1 = 22,000 + 990 = 22,990
So,
S5 = 22,990 + (4.5/100) * 22,990 + (4.5/100) * 22,990 + (4.5/100) * 22,990 + (4.5/100) * 22,990
= $27,037.44
Therefore, the value of the investment after 5 years would be $27,037.44.

N Heracio's Computer Time Shopping Research 10% Videos 15% Homework 20% Games 20% Social dia 25% Heracio used the computer a total of 40 hours last week. How many more hours did Heracio use the computer to do homework than shop online?
Answer: According to the problem, N Heracio used the computer for 40 hours last week. We are asked to find the difference between the time spent on shopping online and doing homework.
To do this, we first need to find the amount of time spent on each activity. We can do this by multiplying the total computer time by the percentage of time spent on each activity:
Time spent on videos = 10% of 40 hours = 4 hours
Time spent on homework = 15% of 40 hours = 6 hours
Time spent on games = 20% of 40 hours = 8 hours
Time spent on social media = 25% of 40 hours = 10 hours
Time spent on shopping online = 20% of 40 hours = 8 hours
Therefore, Heracio spent 6 hours on homework and 8 hours on shopping online.
The difference between these two amounts is:
6 hours - 8 hours = -2 hours
This means that Heracio spent 2 hours more on shopping online than on doing homework.

Billy Bob wants to paint the outside wall of his circular pool. The circular
wall is 4 feet tall and has a radius of 15 feet. If paint cost $28 per gallon and
covers 225 square feet, how much will it cost to paint the wall. The paint is
only avaliable in gallon containers.
The amount it would cost to paint the wall, given the cost of paint and the area covered is $ 56 .
How to find the cost to paint ?The surface area of the circular wall would be :
A = 2 x π x r x h
The area is therefore:
= 2 x π x r x h
= 2 x 3. 14 x 15 x 4
= 376. 8 square feet
The number of gallons needed is therefore:
= 376. 8 / 225
= 1. 674
= 2 gallons
The cost of two gallons is:

37. When making biscuits, a baker
mixes flour and sugar in the ratio
4:1. If he uses 6kg of sugar when
making some biscuits, how much
flour should he use?
(a) 30kg
(b) 24kg
C 10kg
D 8kg
E 1.5kg
The baker should use 24kg amount of flour when making the biscuits. The correct answer is (b) 24kg.
To determine the amount of flour the baker should use when making biscuits, we can use the given ratio of flour to sugar, which is 4:1.
Since the ratio is 4:1, for every 4 parts of flour, there is 1 part of sugar. Therefore, the ratio of flour to sugar can be expressed as 4/1.
If the baker uses 6kg of sugar, we can set up a proportion to find the corresponding amount of flour:
4/1 = x/6
Cross-multiplying, we get:
4 * 6 = 1 * x
24 = x
Therefore, the baker should use 24kg of flour when making the biscuits.
In summary, the correct answer is (b) 24kg.

15x²- 2ax - a² = 0
You would solve this like you would any quadratic. Factor.
Start my multiplying the first and last coefficients
15(-a²) = -15a² =>find 2 numbers that multiply to this but add to middle
term (-2a)
-5a and +3a multiply to -15a² and adds to -2a
Substitute the middle term with the numbers we just found, keeping the x
15x²- 2ax - a² = 0
15x²- 5ax+3ax - a² = 0 > group the first 2 terms and last 2
(15x²- 5ax)(+3ax - a²)= 0 > this is not your factors, you need to take
GCF out of each grouping
5x(3x-a)+a(3x-a)=0 >if the parenthesis is same, you did good
now the parenthesis is your GCF and one of

Kyle is buying gifts for Megan's birthday and needs to stay in budget
Cake = half his money + 36.50
Decorations = half of what he had left + 36.50
Sweets = half of what he had left + 18.25
Now he is out of money, what did he start with?
Answer: Let's start by using algebra to represent the problem.
Let X be the amount of money that Kyle started with.
Then we can create the following equations:
Cake = 0.5X + 36.50Decorations = 0.5(X - Cake) + 36.50Sweets = 0.5(X - Cake - Decorations) + 18.25
And we know that he's out of money, so:
Cake + Decorations + Sweets = XWe can use substitution to solve for X.
Substitute the first equation into the second equation to get:
Decorations = 0.5(X - (0.5X + 36.50)) + 36.50Decorations = 0.25X + 9.25
Substitute the first two equations into the third equation to get:
Sweets = 0.5(X - (0.5X + 36.50) - (0.25X + 9.25)) + 18.25Sweets = 0.25X + 4.75
Substitute all three equations into the fourth equation to get:
(0.5X + 36.50) + (0.25X + 9.25) + (0.25X + 4.75) = X
Simplify and solve for X:
1X + 50.50 = X50.50 = 0.5XX = 101

[tex]r_2 = \dfrac{2}{4} \cdot 30 = 15\\[/tex]
[tex]r_3 = \dfrac{3}{4} \cdot 30 = 22.5\\[/tex]
[tex]r_4 = 30[/tex]
We can now find the area of each red band by subtracting:
the area of the circle within the white band just inward of the red band
-- from --
the area of the circle within the red band.
Finding the area of the outer red band:
[tex]A_{\text{outer red}} = A(\text{circle within outer red}) - A(\text{circle within outer white})[/tex]
[tex]A_{\text{outer red}} = A(\odot \text{ with radius }r_4) - A(\odot \text{ with radius } r_3)[/tex]

Finding the area of the inner red band:
[tex]A_{\text{inner red}} = A(\text{circle within inner red}) - A(\text{circle within inner white})[/tex]
[tex]A_{\text{inner red}} = A(\odot \text{ with radius }r_2) - A(\odot \text{ with radius } r_1)[/tex]
↓ substituting the radius values into the circle area formula ([tex]\pi r^2[/tex])
[tex]A_{\text{inner red}} = (\pi \cdot 15^2) - (\pi \cdot 7.5^2)[/tex]

What are the coordinates of the resulting point, R'?A translation is a type of transformation in geometry that moves a point or an object from one place to another without changing its size, shape, or orientation.
To translate a point, you need to specify the direction and distance of the movement.
Given that:
The point R(1,-2) is being translated 2 units down, which means that it will move vertically downwards by a distance of 2 units.
The x-coordinate will remain the same, as the movement is only in the y-direction.
So, to find the coordinates of the resulting point, R', we subtract 2 from the y-coordinate of the original point R:
R' = (1, -2 - 2)
R' = (1, -4)

Step-by-step explanation:
The markings imply equal sides*
So both of the angles are 27° there
To find angle a we do 180 - (27+27) and obtain 126°
Then to find angle y, we do 180-angle a which is 180-126 and we get 54°
We now have reached the triangle where you're supposed to find x right?
So x is equal to 180 - both other angles, which is 180 - (90 and angle y) = 180- (90+54) = 180 - 144 = 36 which is your final answer
