Michelle bought five packs of crayons for $16.25 What is the cost of a pack of crayons, in dollars, if all the packs cost the same?
Answer:
Michelle bought a pack of crayon for $3.25
Step-by-step explanation:
Number of packs = 5
The cost of a pack of crayons =
(Cost of 5 packs of crayon) / (number of packs of crayons)
The cost of a pack of crayons = ($16.25 ) / 5
The cost of a pack of crayons = $3.25

Sarah's brother is 12 less than twice her age. If Sarah is 16, what equation represents this situation?
The equation that can be used to represent the ages of Sarah and his brother will be 2x - 12 = 16.
How to solve the equationFrom the question given, Sarah's brother is 12 less than twice her age and Sarah is 16.
Let Sarah's age be represented by x.
Therefore, the equation to represent the situation will be:
= (2 × x) - 12 = 16
2x - 12 = 16
2x = 16 + 12.
2x = 28
x = 28/2 = 14
Sarah is 14 years.

What is the length of the hypotenuse of the triangle when x=10?
The length of the hypotenuse is about
Answer:
84 (nearest whole number)
Step-by-step explanation:
If x = 10,
Longest leg = (7 x 10) + 4 = 74
Shortest leg = 4 x 10 = 40
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse of a right triangle):
⇒ 74² + 40² = c²
⇒ 7076 = c²
⇒ c = √7076 = 84.11896...
⇒ hypotenuse = 84 (nearest whole number)
Answer:
84
Step-by-step explanation:
[tex] \sqrt{ {(40)}^{2} + {74}^{2} } = 84.1[/tex]
For every 2 pages of a book that Bernice reads, Charmaine reads 3. When Charmaine
had 16 pages left, Bernice had 36. How many pages are there in the book?
Answer:
76
Step-by-step explanation:
Let x = number of pages
Since Charmaine had 16 pages left, subtract 16 from x to indicate that is the number of pages read like this: x - 16
Divide that by 3 like this: (x - 16)/3
Do the same for Bernice: (x - 36)/2
Make them equal to each other
(x - 16)/3 = (x - 36)/2
Cross multiply
2(x - 16) = 3(x - 36)
Distribute
2x - 32 = 3x - 108
Move like terms to the same side by subtracting 2x from both sides
2x - 32 = 3x - 108
- 2x - 2x
-32 = x - 108
Add 108 to both sides
-32 = x - 108
+ 108 + 108
x = 76
This means there are 76 pages in the book.

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
To verify the identity (cos x / (1 + sin x)) = sec x - tan x, we need to simplify the right-hand side of the equation using trigonometric identities and see if it matches the left-hand side.
sec x - tan x = 1/cos x - sin x/cos x = (1 - sin x)/cos x
On simplifying , we get
cos x / (1 + sin x) = cos x / (1 + sin x) * (1 - sin x)/(1 - sin x) = cos x * (1 - sin x) / (1 - sin²x)
Using the Pythagorean identity sin²x + cos² x = 1, we can substitute 1 - cos²x for sin²x in the denominator:
So , cos x / (1 + sin x) = cos x ( 1 + sin x ) / cos²x
On further simplification , we get
cos x / (1 + sin x) = cos x / cos²x + cos x ( sin x ) / cos²x
cos x / (1 + sin x) = ( 1/cos x ) + ( sin x / cos x )
From the trigonometric relations , we get
cos x / (1 + sin x) = sec x - tan x
Hence , the trigonometric equation is solved

PQ is a straight line segment.According to the information marked in the figure, (I) Find the magnitude of PÔS. (ii) Find magnitude of SÔQ.
PLEASEEEEEEE HEELPPP!!
99 POINTS!! btw turn the attached picture upside down
Answer:
magnitude of PÔS = 60°
magnitude of SÔQ = 120°
note: a straight line has always 180°
solve for x:
PÔS + SÔQ = 180°3x + 2x + 80° = 180°5x = 180° - 80°5x = 100°x = 20°m∠POS
3x 3(20°)60°m∠SOQ
2x + 80°2(20°) + 80°40° + 80°120°So to find angle POS and SOQ we have to find value of x first.

[tex] \rm \angle POS + \angle SOR + \angle ROQ = 180 \degree \\ [/tex]
