The degree measure of an angle in a right triangle is x, and sin x = 1/3 . Which of the following expressions are also equal to
1/3? Select all that apply.
Answer: E only
Step-by-step explanation:
Had the test
The expressions are also equal to 1/3 is cos (90 -x).
What is Complementary Properties of Trigonometry?These relations are valid for all the values of A that lies between 0° and 90°.
sin (90°- A) = cos A ; cos (90°- A) = sin Atan (90°- A) = cot A; cot (90°- A) = tan Asec (90°- A) = csc A; csc (90°- A) = sec AGiven:
sin x = 1/3
Now, using property
sin [tex]\theta[/tex] = cos [tex]( 90- \theta)[/tex]
So, sin x= cos (90 -x)
Hence, The expressions are also equal to 1/3 is cos (90 -x).

Gabby needed to type up 12 documents during the week. By Wednesday, she only finished 3 1/5 documents. On Thursday, she finished another 5 3/4 documents. If she finished writing all documents by Friday, how much did she write on Friday?
Answer: She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.
Step-by-step explanation:
GIven: Total documents needed to be done = 12
If she finished writing all documents by Friday, then the number of documents written on Friday = 12-(work done by Wednesday) - (work done on Thursday)
[tex]= 12 -(3\dfrac15)-(5\dfrac34)\\\\=12-\dfrac{16}{5}-\dfrac{23}{4}\\\\=\dfrac{12\times20-16\times4-23\times5}{20}\\\\=\dfrac{240-64-115}{20}\\\\=\dfrac{61}{20}\\\\=3\dfrac{1}{20}[/tex]
Hence, She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.
Justin is 2 years older than one third Marcella's age. Aimee is is four years younger than 2 times Justin's age. Define a variable and write an expression to represent Justin's age. Then find Justin's age and Aimee's age is Marcella is 63 years old.
Answer:
M x 1/3 + 2. The variable is Marcella's age. If Marcella is 63, one third of her age is 21 so 21+2 = Justin is 23. Aimee is 23x2-4 so she is 62 years old.

Determine whether the lines, 2x – y = 7 and y = – 1/2x – 10 are parallel or perpendicular . Explain the reason for your answer.
Answer:
perpendicular
Step-by-step explanation:
a line is perpendicular to another line when m of one line is the negative or opposite reciprocal of the other. m= 2
the perpendicular lines for that would be 1/2 which is the reciprocal and then the opposite sign which is negative.

Jean writes 75,000,000 in scientific notation as 75 . Explain whether she is correct or incorrect.
Answer:
As Jean writes 75,000,000 in scientific notation as 75.
This is INCORRECT!
The correct solution is:
75,000,000 in scientific notation: 7.5 × 10⁷
Step-by-step explanation:
As Jean writes 75,000,000 in scientific notation as 75.
This is INCORRECT!
Here is the correct solution:
Given the number
75,000,000
Let us write the number 75000000 in scientific notation
We know that scientific notation is of the form [tex]a\times 10^b[/tex] where [tex]1\le a<10[/tex] and b is an integer.
Move the decimal point to the left to create a new number from 1 up to 10.
[tex]a=7.5000000[/tex]
Count the number of times you moved the decimal point
b = 7
so
[tex]=7.5000000\times 10^7[/tex]
Remove the trailing zeros
[tex]=7.5\times \:10^7[/tex]
Therefore, we conclude that:
75,000,000 in scientific notation: 7.5 × 10⁷

What is the greatest possible whole number value of a congruent side lengths?
A. 9cm
B. 10cm
C. 14cm
D. 15cm
Answer:
C. 14cm
Step-by-step explanation:
The square of the longest line, in an obtuse triangle, is greater than the sum of the squares of the other two sides. So it is appropriate for equivalent legs to have a length
L^2 + l^2=2l^2
14^2+14^2=20^
196+196=400
392=400 400
The result: 14cm

Answer:
The perimeter of square will be 18 units
Step-by-step explanation:
We are given that the coordinates of three vertices of a square A (-2 1/2 , 1 1/2), B (-2 1/2 -3), and C (2,1 1/2 )
When point D is placed on this perimeter.
We have to find the perimeter of the square.
First we have to find the side of square by using the distance formula
Distance formula
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Coordinates of A=(-5/2,3/2)
Coordinates of B=(-5/2,-3)
Length of side AB=[tex]\sqrt{(-5/2+5/2)^2+(-3-3/2)^2}[/tex]
Length of side AB=[tex]\sqrt{0+(-9/2)^2}[/tex]
Length of side AB=9/2 units
Now, the perimeter of square=4 (side)
Using the formula
Perimeter of square=4(9/2)=18 units
