The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are [tex]3x,[/tex] [tex]4x-1,[/tex] and [tex]90.[/tex]
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.
[tex]3x + 4x - 1 + 90 = 180.[/tex]
[tex]7x = 91, x = \frac{91}{7} = 13.[/tex]
So x = 13°. The angles are
[tex]3x = 3 (13) = 39, 4x-1 = 4(13) - 1 = 51.[/tex]
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
3x + 4x - 1 = 90⁰
7x = 91
x = 13
Angles are = 39 , 51⁰

Linda and Ralph have signed a contract to purchase a home. The closing date is April 27, and the buyer owns the property on the day of closing The selling price of the
home is $782,500. Linda and Ralph obtained a fixed-rate mortgage from a bank for $685,000 at 7 35% interest. The seller has already paid $14,578.15 in property taxes
for the coming year. How much will Linda and Ralph owe in prorated expenses? (3 points)
Final answer:
Linda and Ralph will owe approximately $9,905.52 in prorated property taxes for the year, after calculating the daily property tax rate and multiplying it by the number of days they will own the home in the current tax year.
Explanation:
Linda and Ralph need to determine their prorated expenses for the property taxes that have already been paid by the seller. To calculate this, we first need to determine the daily property tax rate, and then calculate how much they owe from the closing date, April 27, until the end of the year, December 31.
Calculating the Daily Property Tax Rate
The seller paid $14,578.15 for the full year. There are 365 days in a year, so the daily property tax rate is:
Daily rate = Total annual taxes / Number of days in the year
Daily rate = $14,578.15 / 365
Daily rate ≈ $39.94
Calculating Prorated Property Tax from Closing Date
Linda and Ralph will own the property starting on April 27, and there are 248 days remaining in the year from April 27 to December 31 (inclusive). Therefore, the prorated amount they owe for property taxes is:
Prorated taxes = Daily rate * Number of days from closing to end of year
Prorated taxes = $39.94 * 248
Prorated taxes ≈ $9,905.52
Linda and Ralph will owe approximately $9,905.52 in prorated property taxes for the year.
five times a certain number, minus 5 is equal to 7 more than three times the number
To solve the equation, we can set up the equation as '5x - 5 = 3x + 7' and solve for x using algebraic manipulations.
Explanation:Let's solve this equation step by step. Let's assume that the number we are looking for is 'x'.
According to the question, 'five times a certain number, minus 5' can be represented as 5x - 5. And 'seven more than three times the number' can be represented as 3x + 7.
So, we can write the equation as 5x - 5 = 3x + 7. Now, let's solve for x.
Subtract 3x from both sides: 5x - 3x - 5 = 3x - 3x + 7.
Simplify: 2x - 5 = 7.
Add 5 to both sides: 2x - 5 + 5 = 7 + 5.
Simplify: 2x = 12.
Divide both sides by 2: 2x/2 = 12/2.
Simplify: x = 6.
Therefore, the solution to the equation is x = 6.

Can someone please explain how to do this?
Answer:
e = 30
Step-by-step explanation:
Since 114 and the adjacent angle are supplementary, that means they add up to 180.
114 + x - 114 = 180 - 114
x = 66
Now, solve inside the triangle which adds up to 180.
54 + 66 + 2e = 180
120 + 2e - 120 = 180 - 120
2e / 2 = 60 / 2
e = 30
Answer: e = 30

Factor:
x2 + 9x - 36
Answer:
11x-36
for your answers
Answer:
x= -12
or
x=3
Step-by-step explanation:
in order to factorise the equation x² + 9x - 36
it will be expressed like this to make it a complete equation by subtracting 36 from both sides
x² + 9x - 36=0
the next step is to look for two numbers that when multiplied will give us -36 and when added together it will give us 9.
the numbers would be -3 and 12
so we have
x²-3x + 12x -36 =0
x(x-3) + 12(x-3) = 0
(x+12)(x-3)=0
we have,
x + 12 =0
x = -12
or
x-3 =0
x= 3
Therefore, the factors for x are -12 or 3.

There are 50 runners in a race. How many ways can the runners finish first, second, and third?
Number of ways can the runners finish first, second, and third is 1,17,600 .
Step-by-step explanation:
Permutation is the act of arranging the members of a set into a sequence or order, or, if the set is already ordered, rearranging (reordering) its elements—a process called permuting. For example, written as tuples, there are six permutations of the set {1,2,3}, namely: (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2), and (3,2,1). Formula of Permutation is : [tex]P(n,r) = \frac{n!}{(n-r)!}[/tex] where n is the number of things to choose from, and we choose r of them, no repetitions, order matters. Here , n = 50 , r= 3
⇒ [tex]P(n,r) = \frac{n!}{(n-r)!}[/tex]
⇒ [tex]P(50,3) = \frac{50!}{(50-3)!} = \frac{50(49)(48)47!}{47!}[/tex]
⇒ [tex]P(50,3) = 50(49)(48)[/tex]
⇒ [tex]P(50,3) = 1,17,600[/tex]
∴ Number of ways can the runners finish first, second, and third is 1,17,600 .

There are 7 special subjects at Ichiro's school: art, music, gym, library,
enrichment, typing, and research. Students only take 1 special subject
each school day. A special subject is not taken more than once a week.
Assume that special subjects are assigned randomly.
Ichiro has library on Monday. If the remaining subjects during the school week
are assigned randomly from the other 6 subjects, what is the probability that he
has art on Friday?
Final answer:
The probability that Ichiro has Art on Friday, given that he has already had Library on Monday and the subjects are assigned randomly, is 1/6 or approximately 16.67%.
Explanation:
The subject of this question is Probability. Ichiro has Library on Monday, and since he cannot have the same special subject more than once in a week, there are six subjects left to schedule from Tuesday to Friday. The special subjects are considered to be assigned randomly.
To determine the probability that Ichiro has Art on Friday, we need to consider there are four days left in the school week (Tuesday to Friday) after Monday. Since the subjects are assigned randomly, each of the remaining subjects has an equal chance of being assigned to any day. By the time we get to Friday, there will be only one subject left unassigned, which has a 1 out of 6 chance of being Art, as the remaining subjects are randomly assigned to the days preceding.
The probability that Ichiro has Art on Friday is therefore 1/6, or approximately 16.67%
Which figures are polygons ? Select each correct answer.

Polygons are closed, two-dimensional shapes with straight, fully connected sides. Figure A, Figure B, Figure C are polygons.
To determine which figures are polygons, we must understand that a polygon is a closed, two-dimensional shape with straight sides that are fully connected at each endpoint.
There should be at least two or more straight sides in a polygon.
Figure A: It is a polygon as it has more than two sides and is closed.
Figure B: It is also a polygon as it has 6 sides and angles and is also closed in shape.
Figure C: It is not a polygon as it does not have straight line more than two, it is closed but it contains curved line.
Figure D: It is polygon as it contains straight lines and is closed.

HIJK is a parallelogram. Find w.
*show your work please*
__
giving brainliest to correct answer
Answer:
w = 4
Step-by-step explanation:
Since the figure is a parallelogram, we know that opposite sides must be equivalent. That means that JK = HI. So w + 29 must equal 9w - 3.
Once the problem is set up, it looks like: w + 29 = 9w -3.
Now you have to try to get the variables on one side. To do that, subtract 29 from both sides: w = 9w - 32.
Now subtract 9w from both sides: -8w = -32
Divide both sides by -1 to make them positive: 8w = 32
And divide both sides by 8 to find the value of w: w = 4

A 30° 60° 90° triangle is shown below. Find the length of the side labeled y.
Answer:
Part 1) [tex]y=3\ units[/tex]
Part 2) The length of the hypotenuse is 6 units
Step-by-step explanation:
Part 1) we know that
In the right triangle of the figure
[tex]sin(60^o)=\frac{y}{2\sqrt{3}}[/tex] ----> by SOH (opposite side divided by the hypotenuse)
solve for y
[tex]y=sin(60^o)2\sqrt{3}[/tex]
Remember that
[tex]sin(60^o)=\frac{\sqrt{3}}{2}[/tex]
substitute
[tex]y=(\frac{\sqrt{3}}{2})2\sqrt{3}[/tex]
[tex]y=3\ units[/tex]
Part 2)
Let
h ----> the length of the hypotenuse
we know that
In the right triangle of the figure
[tex]sin(45^o)=\frac{3\sqrt{2}}{h}[/tex] ----> by SOH (opposite side divided by the hypotenuse)
[tex]h=\frac{3\sqrt{2}}{sin(45^o)}[/tex]
Remember that
[tex]sin(45^o)=\frac{\sqrt{2}}{2}[/tex]
substitute
[tex]h=3\sqrt{2}:\frac{\sqrt{2}}{2}[/tex]
[tex]h=6\ units[/tex]
Acos²theta + Bsin²theta = C
Show that
tan²theta =C- A/B-C
[tex]Tan^2x= \frac{C -A}{(B-C)}[/tex]
Step-by-step explanation:
Here we have , Acos²theta + Bsin²theta = C or , [tex]Acos^2theta + Bsin^2theta = C[/tex]
Let theta = x , So [tex]Acos^2x + Bsin^2x = C[/tex] . Let's solve it further
⇒ [tex]Acos^2x + Bsin^2x = C[/tex]
⇒ [tex]\frac{Acos^2x}{cos^2x} + \frac{Bsin^2x}{cos^2x} = \frac{C}{cos^2x}[/tex]
⇒ [tex]A + B(\frac{sin^2x}{cos^2x}) = C\frac{1}{cos^2x}[/tex] { [tex]\frac{sin^2x}{cos^2x} = Tan^2x , \frac{1}{cos^2x} = sec^2x[/tex] }
⇒ [tex]A + B(Tan^2x) = C(sec^2x)[/tex] { [tex]sec^2x=1+Tan^2x[/tex] }
⇒ [tex]A + B(Tan^2x) = C( 1+Tan^2x )[/tex]
⇒ [tex]A + B(Tan^2x) = C+C(Tan^2x )[/tex]
⇒ [tex]B(Tan^2x)-C(Tan^2x ) = C -A[/tex]
⇒ [tex](B-C)(Tan^2x)= C -A[/tex]
⇒ [tex]Tan^2x= \frac{C -A}{(B-C)}[/tex]
Therefore , [tex]Tan^2x= \frac{C -A}{(B-C)}[/tex] .
(a)The area of a rectangular field is 7392 .
If the length of the field is 96 , what is its width?
(b)The perimeter of a rectangular painting is 372 .
If the width of the painting is 88 , what is its length?
Answer:
W = 77
L = 98
Step-by-step explanation:
Question a:
Area of a rectangular field = 7392
Length L = 96
Width w = ?
Area of a rectangle = L x W
7392 = 96 x W
Divide both sides by 96
7392/96 = 96/96 x w
77 = w
W = 77
Question b:
Perimeter of a rectangular painting = 372
Width = 88
Length = ?
Perimeter of a rectangle =
2(L + w)
372 = 2(L + 88)
Distribute 2 into (L + 88)
We have
372 = 2 x L + 2 x 88
372 = 2L + 176
Subtract 176 from both sides
372 - 176 = 2L + 176 - 176
196 = 2L
Divide both sides by 2
196/2 = 2L/2
98 = L
L = 98
What is the slope of the following graph?

A type of bacteria has a very high exponential growth rate of 80% every hour. If there are 10 bacteria, determine how many will be in 5 hours,1 day, and 1 week
Solution:
Given that,
A type of bacteria has a very high exponential growth rate of 80% every hour
There are 10 bacteria
The increasing function is given as:
[tex]y = a(1+r)^t[/tex]
Where,
y is future value
a is initial value
r is growth rate
t is time period
From given,
a = 10
[tex]r = 80 \5 = \frac{80}{100} = 0.8[/tex]
Determine how many will be in 5 hours
Substitute t = 5
[tex]y = 10(1 + 0.8)^5\\\\y = 10(1.8)^5\\\\y = 10 \times 18.89568\\\\y \approx 188.96[/tex]
y = 189
Thus, there are 189 bacteria in 5 hours
Determine how many will be in 1 day ?
1 day = 24 hours
Substitute t = 24
[tex]y = 10(1 + 0.8)^{24}\\\\y = 10(1.8)^{24}\\\\y = 10 \times 1338258.84\\\\y = 13382588.45\\\\y \approx 13382588[/tex]
Thus, there are 13382588 bacteria in 1 day
Determine how many will be in 1 week
1 week = 168
Substitute t = 168
[tex]y = 10(1 + 0.8)^{168}\\\\y = 10(1.8)^{168}[/tex]
Thus there are [tex]10(1.8)^{168}[/tex] bacteria in 1 week

The polygon's are similar. Find the values of x and y.
Answer:
x = 9 y = 27
Step-by-step explanation:
Since the two polygons are similar, we know that they are proportionate to each other. If we divide the values of corresponding sides:
16 ÷ 12 = 1 ¹/₃
32 ÷ 24 = 1 ¹/₃
We now know that the figure on the left is 1 ¹/₃ times the figure on the right. With this information, we can figure out the measurements of the two sides and then find the values of x and y.
6 · 1 ¹/₃ = 8
21 · 1 ¹/₃ = 28
Now that we know the values of each side, we can plug our equations in to find the values of x and y.
x - 1 = 8
x = 9
y + 1 = 28
y = 27
