A - 3/4 = 1/8 step by step explanation
Answer:
A-3/4=1/8 is the equation, if you expand 3/4 it is 6/8, in order to get 1/8 you need to subtract 6/8 from 7/8
7/8-6/8=1/8 therefor A=7/8

x ≈ 1051.368672
Step-by-step explanation for #3:
[tex]tan(\frac{x}{12}) =24[/tex] Use tangent function because it relates to the opposite and adjacent sides of the triangle.
[tex]tan^{-1}(tan(\frac{x}{12}))=tan^{-1}(24)[/tex]

The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).
In this case it is a cube root
The area of a room is 28 sq.cm.If the length of the room was 1m less and its breadth was 2m more than it would be in the shape of a square.Find the length and breadth of the room?
Answer:
Length = 7cm
Breadth = 4cm
Step-by-step explanation:
The shape of the room is original my in a square shape
Area of a rectangle = Length × Breadth
Area = 28 cm²
Length = L - 1
Breadth = B + 2
Hence
28 = (L - 1)(B + 2)
b(b + 3) = 28
b² + 3b = 28
b² + 3b - 28 = 0
b² +7b - 4b - 28 = 0

What is the arc measure, in degrees, of ADC on circle P below?
70°
104°
Answer:
The answer is "[tex]\overarc{ADC} = m\angle CPD + m\angle DPA = 186[/tex]"
Step-by-step explanation:
Please find the image of the question:
In the circle p:
[tex]\to m\angle APB + m\angle BPC + m\angle CPD + m\angle DPA = 360^{\circ} \\\\\to 70 + 104 + m\angle CPD + m\angle DPA = 360\\\\\to m\angle CPD + m\angle DPA = 360 - 70 - 104 = 186[/tex]
Let P is in the center
[tex]\to[/tex] arc AD= [tex]m\angle APD[/tex]
[tex]\to[/tex] arc DC = [tex]m\angle CPD[/tex]
[tex]\to[/tex] arc BC = [tex]m\angle BPC[/tex]
arc AB =
When D is on arc AC:
[tex]\to[/tex]arc ADC = arc AD + arc DC
[tex]\to[/tex]arc ADC = [tex]m \angle CPD + m\angle DPA = 186[/tex]

2) Mr. Jenkins deposited $1,200 into an account. He made no additional
deposits or withdrawals. Jenkins earned 4.0% annual simple interest on
the money in the account. What was the balance in dollars and cents in
Mr. Jenkins's account at the end of 4 years?
Hello, I Am BrotherEye
Answer:
The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Initial deposit = $ 1,250
Interest rate = 4.25% annual simple = 0.0425
Time of investment = 4 years
2. What was the balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years?
Let's recall the simple interest formula, as follows:
A = P * (1 + rt), where:
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the values we know:
A = P * (1 + rt)
A = 1,250 * (1 + 4 * 0.0425)
A = 1,250 * 1.17
A = 1,462.50
The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50

For two events X and Y, P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5 . Find the probabilities.
1. 2/25 P(Y∩X) = ____
2.4/15 P(Y)· P(X) =____
Answer:
1. 2/25
2. 4/15
Step-by-step explanation:
1. P(Y∩X)
Since P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5, this is a conditional probability.
So P(Y∩X) = P(Y)P(X|Y) = 2/5 × 1/5 = 2/25
2. P(Y)· P(X)
P(Y)· P(X) = 2/3 × 2/5 = 4/15

Find the area of the given trapezoid.
240 is the answer you're looking for!
Step-by-step explanation:
To find the area, spilt the trapezoid into 3 shapes.
2 triangles (at the ends) and 1 rectangle (the center).
Let's start with the rectangle, the formula for rectangle area is:
[tex]l*w=A[/tex]
The length of the rectangle is 12, the width is 20. Add the numbers in:
[tex]12*20=A[/tex]
Solve:
[tex]12*20=240[/tex]
The area of the rectangle is 240. Now solve for the Triangles.
The formula for finding the area of triangles are is:
[tex](L*W)/2[/tex]
The length of the triangle is 12. To find the width subtract 20 from 30.
L = 12, W = 10. Add in the numbers.
[tex](12*10)/2 = A[/tex]
Use order of operations to solve, start with parenthesis:
[tex]120/2=A[/tex]
Rember to divide it by 2 because a triangle is half of a rectangle.
[tex]60 =A[/tex]
Since there are two identical triangles, you don't need to solve for the other
Now, add the areas together:
[tex]60 + 120+60=A[/tex]
Then solve:
[tex]180+60=A[/tex]
[tex]240=A[/tex]
The correct answer is 240.

PLEASE HELP GIVING BRAINLIEST
Answer:
B=10^18
Step-by-step explanation:
A=10*log(B)
180=10*log(B)
18=log(B)
10^18=10^log(B)
10^18=B
Therefore, B=10^18
River City Middle School has a weekly contest. The prize is a season pass
to the city amusement park. This week's contest is to guess the number
of lemon jellybeans in a jar of 800 jellybeans. Gerald counted in 3
different sections on the outside of the jar. Here are his results:
5 lemon jelly beans out of 30 jellybeans.
4 lemon jelly beans out of 22 jellybeans.
2 lemon jelly beans out of 12 jellybeans.
based on his sampling, how many lemon jellybeans should he guess are in the jar? Show the mathematics you used to support your answer !
PLEASE HELP
Answer:
150 lemon jellybeans
Step-by-step explanation:
Add the ratios up to get 12 lemon jelly beans out of 64 jellybeans.
[tex]\frac{12}{64} =\frac{x}{800}[/tex]
Cross multiply:
9600 = 64x
---> x = 150 lemon jellybeans
A parallelogram has four angles that are the same measure. Is it a square?
Choose Yes or No to tell if the answer and explanation is correct.
Yes. Only squares have four angles that are the same measure.
Yes. It could be a square if all sides are also the same measure.
No. If the sides are not the same length, it is not a square.
No. The figure is a rhombus.
Answer:
Yes
Step-by-step explanation:
Yes. It could be a square if all sides are also the same measure.
A parallelogram will be a square when all four sides are of equal in length and all four angles are same.
A parallelogram is a quadrilateral with opposite sides parallel . A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.A square is a parallelogram when all four sides of parallelogram are same and all four angles are equal to 90 degree.Learn more:

A Choir director made a histogram showing his ages of the members in choir which statement about the data in the histogram must be true
Answer:
C) The choir has a total of 100 members
Step-by-step explanation:
Histogram is the graphical representation of data with the use of bars of different heights.
From the histogram attached:
A) Number of people fro 46 to 73 years = 30 + 5 + 15 = 50
Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100
Therefore half of the people are from 46 to 73 years.
Therefore the statement that more than half of the people are from 46 to 73 years is wrong.
B) The histogram shows the number of members between each age range, it does not show the number of male and female members. Hence we cannot determine the number of male and female members.
C) Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100
The choir has a total of 100 members
D) Number of people less than 32 years = 15 + 20 = 35
Therefore the statement that exactly 20 members are less than 32 years is wrong
The temperature was 48°F and dropped 15° in two hours.
What was the temperature after the change?
Answer:
33 degrees Fahrenheit.
Step-by-step explanation:
If the temperature was 48 degrees, and it dropped 15, that means the initial temperature was subtracted by 15.
48 - 15 = 33.
Answer:
33°F
Step-by-step explanation:
The initial temperature was 48°F. Then, it dropped by 15°.
I am assuming that both values are given in the same unit.
48 - 15 = 33
The temperature should be 33 degrees now.
