Find the angle between the diagonal of a cube of side length 15 and the diagonal of one of its faces, so that the two diagonals have a common vertex. The angle should be measured in radians. (Hint: we may assume that the cube is in the first octant, the origin is one of its vertices, and both diagonals start at the origin.)
Answer:
the angle between the diagonal is 0.6155 RADIANS
Step-by-step explanation:
Given the data in the question
as illustrated in the image below;
O is [0,0,0]
B is [15,0,15]
E is [15,15,15]
Now to find angle BOE
vector OB = [15,0,15]
vector OE = [15,15,15]
OB.OE = [15,0,15].[15,15,15] = 15 × 15 + 15 × 15 = 450 = |OB||OE|cos[angleBOE]
|OB| = √(15² + 15²) = √(225 + 225) = √450
|OE| = √(15² + 15² + 15²) = √(225 + 225 + 225) = √675
so
Angle BOE = cos⁻¹ ( 450 / ( √450 × √675 )
Angle BOE = cos⁻¹ ( 0.81649 )
Angle BOE = 35.265°
Angle BOE = 0.6155 RADIANS
Therefore, the angle between the diagonal is 0.6155 RADIANS

What is the value of h?
Give your answer correct to 1 decimal place.
The diagram is missing, so i have attached it.
Answer:
h = 7.7 cm
Step-by-step explanation:
From the attached image, we can see that the hypotenuse is 15 cm with the opposite side being h cm.
The angle is 31°
Thus, using trigonometric ratio, we have;
h/15 = sin 31
h = 15 sin 31
h = 15 × 0.5150
h = 7.725
Approximating to 1 decimal place gives;
h = 7.7 cm

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online file below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error.
Answer:
A. 384.16
B. 2,401
C. 9,604
D. No
Step-by-step explanation:
Calculation to determine how large a sample should be taken for each desired margin of error
First step is to find σ which represent Population Standard deviation
σ=($50,000-$30,000)/4
σ=$20,000/4
σ = 5,000
Now let calculate how large a sample should be taken for each desired margin of error
Using this formula
n = (Za/2*σ/E)^2
Where,
Za/2=1-0.95/2
Za/2=0.05/2
Za/2=0.025
Z-score 0.025=1.96
Za/2=1.96
σ =5,000
E represent Desired margin of error
Let plug in the formula
a. $500
n = (1.96* 5,000/$500)^2
n=(9,800/$500)^2
n=(19.6)^2
n = 384.16
b. $200
n = (1.96*5,000/200)^2
n=(9,800/$200)^2
n=(49)^2
n = 2,401
c. $100
n = (1.96*5,000/$100)^2
n=(9,800/$100)^2
n=(98)^2
n = 9,604
Therefore how large a sample should be taken for each desired margin of error will be :
A. $500= 384.16
B. $200= 2,401
C. $100= 9,604
d.NO, Based on the information calculation i would NOT recommend trying to obtain the $100 margin of error reason been that it is highly costly compare to $500 margin of error and $200 margin of error.

2/9 of the students in a school are in sixth grade.
a. How many sixth graders are there if the school has
90 students?
b. How many sixth graders are there if the school has
27 students?
c. if the school has x students write an expression for the number of students of sixth graders in terms of x
d. how many students are in the school of 42 of them are in 6th grade
Answer:
a) 20 sixth graders.
b) 6 sixth graders.
c) 2/9x sixth graders.
d) 189 students in the school.
Step-by-step explanation:
a) 2/9 of 90 = 2/9 * 90 = 20 students.
b) 2/9 of 27 = 2/9 * 27 = 6 students.
c) 2/9 of x = 2/9x
d) 42 = 2/9x so solve the equation: x = 189 students.
If we have 90 students in the school then we will have 20 sixth grade students.
a. From the details of the question, we have 2/9 of the students in the school in sixth grade. Hence;
Number of students in sixth grade = 2/9 × 90 = 20 sixth grade students
b. If the school has 27 students, number of sixth graders = 2/9 × 27 = 6 sixth grade students
c. If we have x students in the school, the number of sixth graders = 2/9 × x = 2/9x students
d. If we have 42 students in sixth grade, the number of students in the school is;
2/9 × x = 42
x = 9/2 × 42 = 189 students

2. service sells 12 songs
for $9.96. At this rate,
how many songs
can you purchase
for $4.15?
Answer:
You can buy 5 songs.
Step-by-step explanation:
First, you would divide 9 by 12 which is 0.83, assuming that each song costs 0.83 by itself you would just add 0.83 + 0.83 until you reach 4.15, the amount of times you added is the answer, which is 5 lolz
Find the value of X round to the nearest 10th
Answer: 22.1°
Step-by-step explanation:
Applying law of sines, we have:
8² = 19² + 14² - 2*14*19 * Cos(x)
64 = 557 - 532*cos(x)
64 - 557 = -532*cos(x)
-493 = -532*cos(x)
Divide both sides by -532
-493/-532 = cos x
0.926691729 = cos x
x = cos^-1(0.926691729)
x = 22.1° (nearest tenth)
9+3+x-y; use x=6, and y=2
Answer:
If x=6 & y=2 then 9+3+x-y wil be
9+3+6-2
=12+6-3
=18-3
=15
Answer:
Given, x=6 and y=2
so the expression we have 9+3+x-y will become,
9+3+6-2 !
and by adding 9 & 3 we will get,
=12+6-3
Now adding 12 & 6 we get,
=18-3
now by subtracting 3 from 18 we get,
=15

How can I find the area for this shape please help!
Answer:
12cm²
Step-by-step explanation:
a=l·w
the easiest way to find the area is to break up the shapes.
the smaller shape is 1cm by 2cm
1·2= 2 cm
the larger shape is 5cm by 2cm
5·2= 10 cm
add them
2+10= 12cm
Answer:
12cm^2
Step-by-step explanation:
These are two rectangles if we divide.
So,
Area of rectangle = length × breadth
So we will name the bigger rectangle as R1 and the smaller rectangle as R2.
So,
Area of R1 = l × b
Area of R1 = 5×4
Area of R1 = 5 × (4-2)
Area of R1 = 5 × 2
Area of R1 = 10 cm^2
Area of R2 = l × b
Area of R2 = (4-2) ×1
Area of R2 = 2 × 1
Area of R2 = 2cm^2
So,
Area of complete figure = Area of R1 + Area of R2
Area of complete figure = 10 + 2
Therefore, Area of complete figure = 12cm^2
Hope it helps!!!!
