8:4 and 16:64 are equal ratios?

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

Answer:

$8.99

Step-by-step explanation:

$38.95- $11.98 = $26.97
$26.97 / 3 pizzas = $8.99

The equation that can be used to represent the ages of Sarah and his brother will be 2x - 12 = 16.

From 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.

Step-by-step explanation:

The trigonometric value identity is solved (cos x/1 + sin x) = sec x - tan x

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

Answer: v = -13

Step-by-step explanation:

Multiply both sides of the equation by (v+12). On the right side, the (v+12) terms will cancel leaving only (v+4). On the left, we will have 9(v+12). Therefore:

[tex]9(v+12)=v+4[/tex]

Distribute the 9 into the parenthesis to get:

[tex]9v+108=v+4[/tex]

Subtract 'v' on both sides to get:

[tex]8v+108=4[/tex]

Subtract 108 from both sides to get:

[tex]8v=-104[/tex]

Divide both sides by 8 to get:

Answer:

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.

Answer:

magnitude of PÔS = 60°

magnitude of SÔQ = 120°

note: a straight line has always 180°

solve for x:

m∠POS

m∠SOQ

So to find angle POS and SOQ we have to find value of x first.

[tex] \\ [/tex]

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

Reason:-

Sum of angles on same line.

By the way it can be any number of angles but they should meet at same point. And their sum is always 180°. Remember linear pair? It is also same aspect but there will be only two angles.

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)
