What is the value of x in the fraction?
9514 1404 393
Answer:
x = 11
Step-by-step explanation:
A 2-digit repeating decimal fraction will have two 9s as the denominator. In this case the fraction can be reduced.
[tex]0.\overline{27}=\dfrac{27}{99}=\dfrac{3}{11}[/tex]
Comparing this to 3/x, we see that x = 11.

In the figure shown below, lines j and k are parallel. Which equation can be used to find the value of x in the figure?
Answer:
Step-by-step explanation:
D b/c you know that the two angles add to 180°
The solution is Option D.
The value of x can be calculated from the equation
( x + 40 ) + ( 2x + 20 ) = 180
What are Parallel Lines Cut by Transversal?
Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles
Given data ,
Let the parallel lines be j and k
The transversal line is m
Now , the value ( 2x + 20 )° lies on one side of the transversal line
And the value ( x + 40 )° lies on one side of the transversal line
The total angle of a line is 180°
So ,
The sum of ( 2x + 20 )° and ( x + 40 )° will be 180°
Therefore , The solution is ( x + 40 ) + ( 2x + 20 ) = 180
Hence , The value of x can be calculated from the equation
( x + 40 ) + ( 2x + 20 ) = 180

can someone explain how 1/4 × 900/1 is equal to 225, my mom is asking for an explanation and I used a calculator help me
Answer:
See below
Step-by-step explanation:
[tex] \frac{1}{4} \times \frac{900}{1} \\ \\ = \frac{1 \times 900}{4 \times 1} \\ \\ = \frac{900}{4} \\ \\ = \frac{9 \times \cancel {100} }{\cancel4} \\ \\ = 9 \times 25 \\ \\ = 225[/tex]
Answer:
four of 225 makes 900/1, or 900. So, one 225 should be one of the four 225s that equal 900. 1/4 × 1/900, or 1/4 of 900, should be 225.

If the balance at the end of eight years on an investment of $196 that has been invested at a rate of 9% is $337.12, how much was the interest
Answer:
$141.12
Step-by-step explanation:
Initial investment = $196
After 8 years with 9% interest rate it becomes: $337.12
The amount of interest will be:
= $337.12 - $196

A trombone acts like an open pipe of length 2.96 m .On a cold day it plays,its 4th harmonic at 221 hz what is the speed of the sound waves in the horn that day?
Answer:
327.08 m/s
Step-by-step explanation:
Given that:
Length of pipe = 2.96m
4th harmonic frequency = 221 Hz
Speed of wave in the horn :
Speed of wave (v) = fλ
For 4th harmonic :
Wavelength, λ = (2/4)L
λ = L/2 ; 2λ = L
2λ = 2.96
λ = 2.96 / 2
λ = 1.48 m
Hence, speed of wave in the horn = 221 * 1.48 = 327.08 m/s

Use the scale drawing and the scale factor to enlarge a square that has a side length of 12 in. Scale factor= 3 in:2m.
Which proportion could you use to solve the side length, x, of the enlarged square?
Given:
The side of square = 12 in.
Scale factor of enlargement = 3 in : 2 m
To find:
The proportion that is use to solve the side length, x, of the enlarged square.
Solution:
Let, the side of length of enlarged square = x m
In case of enlargement the corresponding sides are proportional.
[tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex]
[tex]3x=2\times 12[/tex]
[tex]3x=24[/tex]
Divide both sides by 3.
[tex]x=\dfrac{24}{3}[/tex]
[tex]x=8[/tex]
Therefore, the required proportion is [tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex] and the side length of the square after enlargement is 8 m.

What is the value of the expression? (10 1/4 +61) – (3 3/5 - 3 1/2) Enter your answer in the box as a mixed number in simplest form.
Answer:
71 3/20Step-by-step explanation:
This is easy. The first step here is to simplify the numbers inside the parentheses.
10 1/4 + 61 = 71 1/4
3 3/5 - 3 1/2 = 3 6/10 - 3 5/10 (We needed to get both with like denominators, so we raised the fractions to an equivalent denominator.)
3 6/10 - 3 5/10 = 1/10
Now, we will do the operation outside of the parentheses.
71 1/4 - 1/10 = 71 5/20 - 2/20 = 71 3/20

Other points represent coordinates of:
A=(6, π/12), C=(-6, -π/12), D=(6, -π/12)This is point B and correct choice is option B.
9514 1404 393
Answer:
point C
Step-by-step explanation:
The given coordinates (-6, π/12) are equivalent to (6, 13π/12). That is, the negative radius is equivalent to a positive radius in the opposite direction (angle different by π radians).
The point on the diagram with coordinates (6, 13π/12) is point C.

The value of A from the given equation is A=B³/(D-2q).
The given equation is DA-2qA=B³.
We need to solve the given equation for A.
What is an equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, DA-2qA=B³ can be solved for A as follows:
A(D-2q)=B³
⇒A=B³/(D-2q)
Therefore, the value of A from the given equation is A=B³/(D-2q).

Which Inequality is shown on the accompanying graph (image included)
If you can, pls explain :’)
Answer:
4. x ≥ -1
Step-by-step explanation:
The graph shows a directed line that starts at -1 towards the your right. The full circle indicates that -1 is included among the possible values of x. This means that all possible values of x include -1 and above.
Therefore, we can say x is greater than or equal to -1.
This is represented as:
x ≥ -1
1. Yejin plans to retire at age 60. She wants to create an annuity fund, which will pay her a monthly allowance of $4000 during her retirement. She wants to save enough money so that the payments lasts for 30 years. A financial advisor has told her the she can expect to earn 5% interest on her funds, compounded annually.
2. Yejin has just turned 28 years old. She currently has no retirement savings. She wants to save part of her salary each month into her annuity fund. Calculate the amount Yejin needs to save each month, to meet her retirement goal.
9514 1404 393
Answer:
$3891.10
Step-by-step explanation:
This question is a bit unusual in that the interest is compounded annually, but payments and withdrawals are made monthly. The effective monthly rate is ...
1.05^(1/12) -1 = 0.407412378% = i
We assume that payments to the annuity are made at the end of the month, and that withdrawals are made at the beginning of the month. (The last payment and the first withdrawal are made on the same day.)
The amount of money required in the fund is ...
A = $4000(1 -(1.00407^-360))/(1 -1.00407^-1) = $757,712.88
The amount of money needed each month to be put into the fund is P, where ...
$757,712.88 = P(1 -1.00407)^(-12(60-28))/(1 -1.00407^-1) = 194.7297P
P = $757,712.88/194.7297 = $3891.10
Yejin needs to save $3891.10 each month to meet her retirement goal.
_____
Sanity check
Yejin wants payments for 30 years from the fund to which she has contributed for 32 years. The similarity of the time periods means that Yejin's monthly contribution will need to be very similar to the amount she plans to withdraw.
The only ways to reduce the required contribution are to earn a higher interest on deposits, or to adjust the relative time periods (retire later).
