Answer:
x = 3 will be the answer.
Step-by-step explanation:
From right triangle ABC,
By applying Sine rule,
Sin45° = \(\frac{\text{Opposite side}}{\text{Hypotenuse}}\) = \(\frac{BC}{AC}\)
\(\frac{1}{\sqrt{2}}\) = \(\frac{BC}{6\sqrt{2}}\)
BC = 6 units
Now from right triangle BCD,
By applying Cosine rule,
Cos60° = \(\frac{\text{Adjacent side}}{\text{Hypotenuse}}\) = \(\frac{BD}{BC}\)
\(\frac{1}{2}=\frac{x}{6}\)
x = \(\frac{6}{2}\)
x = 3

Translate the following phrase to a mathematical expression.
a number times fifteen
(A) 15 n
(B) 15 + n
(D) 15 ÷ n
(C) n15
Answers
Answer:
I think C
Step-by-step explanation:
A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

(solve, show work) Jennifer earns $1,920 in interest after making a deposit 6 months ago at a rate of 12.5%. What was the initial deposit 6 months ago? PLS answer this seriously its really important tysm!
Answers
Answer:
P = $1807.058
Step-by-step explanation:
Given
A=$1, 920
R=12.5% =12.5/100
T= 6month = 6/12 .... to change to year
Required
p=?
Solution
A= I + P ......... I= PRT
A = PRT + P
A= P(RT+1)
$1920 = P( 12.5/100 ( 6/12) + 1 )
$1920= P(1.0625)
P = $ 1920 / 1.0625
P = $1807.058
We can use the simple interest formula to solve this problem. The formula is:
I = P*r*t
where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate, and t is the time in years.
First, we need to convert the annual interest rate of 12.5% to a monthly rate. We can do this by dividing the annual rate by 12 (the number of months in a year):
r = 12.5%/12 = 0.01041667
Next, we need to convert the time of 6 months to a fraction of a year. We can do this by dividing 6 by 12:
t = 6/12 = 0.5
Now we can plug in the given values and solve for P:
I = P*r*t
$1,920 = P*0.01041667*0.5
$1,920 = P*0.00520833
P = $1,920/0.00520833
P = $368,640
Therefore, the initial deposit 6 months ago was $368,640.

A figure is dilated using a scale factor of -1. how can you obtain the image without using a dilation? Explain your reasoning.
Answers
Answer: Rotate the point 180 degrees around the origin
==========================================================
Explanation:
Consider the point (2,3). Applying a dilation of scale factor -1 means we multiply each coordinate by -1. That moves us from (2,3) to (-2,-3). This rotates the point 180 degrees about the origin. It can be done clockwise or counterclockwise.
---------------------
Extra Side Notes:
The 180 degree rotation rule is \((x,y) \to (-x,-y)\)The three points (x,y), (-x,-y) and (0,0) all are on the same straight line.The preimage and image are the same size, since the absolute value of the scale factor is 1. The rotation preserves the size.78% of x is 3.822, y% of 8 is 0.248
Answers
To solve for x and y, we can use the following equations based on the information given:
1.) 78% of x is 3.822:
0.78x = 3.822
x = 3.822/0.78
x ≈ 4.900
Therefore, 78% of x is approximately 3.822 when x is approximately 4.900.
2.) y% of 8 is 0.248:
(y/100)8 = 0.248
y/100 = 0.248/8
y/100 = 0.031
y = 0.031100
y = 3.1
Therefore, y% of 8 is 0.248 when y is equal to 3.1.

The line plots below show the number of students in each of Andre’s and Mandy’s classes at school. Approximately how many times larger is the difference between the means of the number of students in Andre’s and Mandy’s classes compared to the range?
Answers
Answer:
the answer is 5.0
Step-by-step explanation:
The difference between the means of the Andre's and Mandy's classes are 1.42. \(X_{AM}=1.42X_{MM}\)
What is mean?The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
From the data given we will calculate the mean of andres's class students and mandy's class students.
For Andre's
\(X_{AM}=\dfrac{20+21+22+23+25}{5}=22.5\)
For Mandy
\(X_{MM}=\dfrac{14+15+15+16+19}{5}=15.8\)
So here we will compare the means
\(\dfrac{X_{AM}}{X_{MM}}=\dfrac{22.5}{15.8}=1.42\)
\(X_{AM}=1.42X_{MM}\)
