Given:
Angle = 44 degrees.
Adjacent side = 6 units.
Hypoteuse side = x units
Recall the formula for cosine,

Solve for angle FGD
Answers
Answer:
m∠FGD = 132°
Step-by-step explanation:
Corresponding Angles Postulate
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
Therefore, as AB is parallel to CD, and line EH intersects them:
⇒ m∠EFB = m∠FGD
Substitute the given expressions for the angles and solve for x:
⇒ (3x - 120)° = (x + 48)°
⇒ 3x - 120 = x + 48
⇒ 3x - 120 - x = x + 48 - x
⇒ 2x - 120 = 48
⇒ 2x - 120 + 120 = 48 + 120
⇒ 2x = 168
⇒ 2x ÷ 2 = 168 ÷ 2
⇒ x = 84
Substitute the found value of x into the expression for m∠FGD:
⇒ m∠FGD = (84 + 48)°
⇒ m∠FGD = 132°

Answers
The area of a circle is given by the following formula:
[tex]A_C=\pi\cdot r^2[/tex]where r is the lenght of the circle's radius.
In this case, we have a radius of 12 units, so the area will be
[tex]A_C=\pi\cdot12^2=3.14\cdot144=452.16[/tex]We are however, asked to find the area of the shaded region, which is encased within a square. From the image we can see that the circle's radius is half the length of a side of the square. In other words, the square's sides measure 24 units.
The area of a square is given by
[tex]A_S=s^2[/tex]where s is the lenght of the sides of the square. In this case,
[tex]A_S=24^2=576[/tex]Now, in order to determine the area of the shaded region, we subtract the area of the circle from the area of the square:
[tex]A_R=A_S-A_C=576-452.16=123.84[/tex]So the area of the shaded region is 123.84 square units.

Your answer is incorrect. A house has increased in value by 24% since it was purchased. If the current value is $527,000, what was the value when it was purchased? $102.000
Answers
We are given the final value of the house after its price was increased by 24%
We must go back to the original price knowing the final price. It's called inverse percentage calculation
To calculate the 24% of the value, we multiply by 24 and divide by 100, that is
value * 24 / 100 = 0.24 * value
The original price of the house is 100%, the increase is 24%, thus the final value of the house is 100% + 24% = 124%
What we were given as data is 124% of the original price of the house
As we did above, to compute 124% of a value, we multiply by 124 and divide by 100. Being P the original price of the house, then the final value is
P * 124% = P * 124 / 100 = 1.24 * P
We know this value:
1.24 * P = $527,000
Divide by 1.24 both sides of the equation
P = $527,000 / 1.24 = $425,000
The original price of the house was $425,000
Let's check it out:
Original price: $425.000
Increase: 0.24 * 425,000 = $102,000
Final Price: $425,000 + $102,000 = $527,000

Step-by-step explanation:
40 yards / 10 quilts = 4 yards per quilt
12 * 4 = 48
Hope this helps.
Answer:
48 yards
Step-by-step explanation:
Hey there!
To find the answer, we must first find how much yards of yarn she needs for 1 quilt
we do, 40/10 which is 4
Meaning, she needs 4 yards of yarn to make 1 quilt
Now we multiply 4 by 12 since we are making 12 quilts
4 x 12 = 48
So, Natalie needs 48 yards of yarn to make 12 quilts

Answers
Answer:
First Solution: 8.5mL
Second Solution: 42.5 mL
Explanation:
Let us call x the number of mL of the first solution and y the number of mL of the second solution.
Now, from the fact that the final solution is 51 mL, we know that
[tex]x+y=51[/tex]Furthermore, from the fact that the final solution 40% carbonated water, meaning there are in total
[tex]51\times\frac{40}{100}=20.4mL[/tex]of carbonated water in the love potion.
Now, the first solution contributes 15/100 * x mL of carbonated water in the solution whereas the second solution contributes 45/100 * y mL. Since all 20.4 mL of carbonated water in the solution is coming from solution 1 and 2, then it must be that
[tex]\frac{15}{100}x+\frac{45}{100}y=20.4[/tex][tex]0.15x+0.45y=20.4[/tex]Thus we have two equations and two unknowns
[tex]\begin{gathered} 0.15x+0.45y=20.4 \\ x+y=51 \end{gathered}[/tex]We solve the above system by elimination.
First multiplying the second equation by 0.15 gives
[tex]\begin{gathered} 0.15x+0.45y=20.4 \\ 0.15x+0.15y=51\cdot0.15 \end{gathered}[/tex]which simplifies to give
[tex]\begin{gathered} 0.15x+0.45y=20.4 \\ 0.15x+0.15y=7.65 \end{gathered}[/tex]Subtracting the first equation from the second gives
[tex]0.30y=12.75[/tex]Finally, dividing both sides by 0.30 gives
[tex]\boxed{y=42.5.}[/tex]With the value of y in hand, we now put it into x+ y = 51 and solve to x to get
[tex]x+42.5=51[/tex]subtracting 42.5 from both sides gives
[tex]\boxed{x=8.5.}[/tex]Hence, to conclude the needed amounts of the solution are:
First Solution: 8.5mL
Second Solution: 42.5 mL

Ben takes out a loan of $2,500 with a 5.5% interest rate that is compounded semi-annually.
If he pays off the loan in 5 years, how much will he end up paying? Round your answer to the nearest dollar.
Answers
Ben end up paying $3279.12 over the course of five years with rate of interest 5.5% for a principal of $2500.
Explanation:Compounding interest semiannually means that at the start of the compounding period, in this case, every six months, the principal of a loan or investment includes the total interest from the previous period.
In the question, we are given the following information:
P = $2500
r = 5.5% = 0.055
t = 5 years
n = 2
The compound interest is calculated as follows:
A = [tex]P(1 + r/n)^{nt}[/tex]
where A denotes the amount, p denotes the principal, r denotes the interest rate, t denotes the time in years, and n denotes the type of compound interest.
A= 2500( 1 + 0.055/2)¹⁰
= 3279.12 ≈ $3279
A = $3279.12
Ben will end up paying $3279.12 at the end of 5 years for n = 2.
