IK this is simple math but I need help.

Answer:

x = 8, y = 4

Step-by-step explanation:

To find x use the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , thus

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

x × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

x = 8

--------------------------------------------------------------

To find y use the tangent ratio in the right triangle and the exact value

tan60° = [tex]\sqrt{3}[/tex] , thus

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )

4[tex]\sqrt{3}[/tex] = y × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

y = 4

A line that goes through the origin represents a proportional relationship.  Since the line passes through zero-zero, it means that the relationship between the number of notebooks and the cost is proportional The unit rate is represented by the point one-y. The point one, two and seventy-five hundredths represents the unit rate, which means each notebook costs two dollars and seventy-five cents.

Answer:

1/2 o 50%

Step-by-step explanation:

debemos partir de la presuncion que un bebe puede ser niño o niña uinicamente, o sea la P(niño) + P(niña) = 1

no existen los bebes que son niños y niñas al mismo tiempo, eso quiere decir que es una opcion o la otra

P(niña) = 1 - P(niño) = 1 - 1/2 = 1/2 = 0.5 = 50%

  yes, yes, no, no

Step-by-step explanation:

An equation is linear if no term has a variable with an exponent other than 0 or 1. There can be no products of variables.

The equations with terms x³ or x² will not be linear.

(a, b) linear (yes)

(c, d) not linear (no)

Answer:

of what exactly and thanks for the points

Answer:

32

Step-by-step explanation:

(n/2) − 10 = 6

Add 10 to both sides.

n/2 = 16

Multiply both sides by 2.

n = 32

Answer:

n=32

Step-by-step explanation:

n/2 - 10=6

add 10 on both side

n/2 +10-10=6+10

n/2=16

multiply both side by 2

n/2×2=16×2

n=32

Answer:

oof good luck tho let me know the answer

Step-by-step explanation:

7.3 meters

Step-by-step explanation:

hypotenuse = 18

angle depression = 24 degrees

missing side = opposite, x

since this has opposite and the hypotenuse were going to use sin

sin(24 degrees) = .40673664307

multiply .40673664307 by the length (18) = 7.32125957526 rounded down =7.3 meters

The depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A fishing boat has snagged a fish and wants to know the depth of the fish. If there are 18 meters of fishing line out and the angle of depression is 24º

We can draw a right-angle triangle:

From the right-angle triangle:

Let x be the depth of the fish.

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying sin ratio:

sin24 = x/18

x = 18sin24

x = 7.32 meters ≈ 7.3 meters

Thus, the depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.

Answer:

[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

On your recent question- you stated that when the x value was 10, the y value was 2. The graph started at the origin. To find the constant of proportionality, use the equation [tex]\frac{rise}{run}[/tex]. In this case, the "run" was 10, since it went +10 from 0. The "rise" was 2, since it went +2 from 0.

[tex]\frac{2}{10} = \frac{1}{5}[/tex] simplified.

Answer:

27

Step-by-step explanation:

Set up a proportion.

1 day / (2/3 cup) = x/ 18 cups            Cross Multiply

1 day * 18 cups = 2/3 cup * x            Multiply both sides by 3

1 day * 18 cups * 3 = 2x

54 day cups = 2x cups                    Divide by 2

54 day cups/2 cups = x

27 days (The cups cancel)

Answer:

27 days it will last
