Answer:

y = -4

Step-by-step explanation:

When y is directly proportional to x,

= y ∝ x

= y = kx

Finding k

the value of y = -2 when x = 4

-2 = k4

k = -2/4

k = -1/2

. What is the value of y when x = 8

Finding y

y = kx

y = -1/2 × 8

y = -4

Answer:

Step-by-step explanation:

take angle A as reference angle

using cos rule

cos A=adjacent/hypotenuse

cos A=12/13

cos A=0.92

A=cos 23

A=23 degree

for ratio,

cos A=12/13

Cos( A ) = AC / AB [ Ratio ]

Cos( A ) = 12 / 13 [ Ratio ]

Cos( A ) = 0. 92307 [ Exact value ]

Step-by-step explanation:

Circumference = 2×π× radius

Circumference = 2 × 3.14 × 3

Circumference = 18.84

Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.

But is there a fee for the question?

These two laws can help you in the question:

Circumference = π× diameter of the circle. Circumference = 2×π× radius

The circumference of the yellow circle should be considered as the 18.84.

Since

The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm

So here the circumference be like

= 2×π× radius

= 2 × 3.14 × 3

= 18.84

hence, The circumference of the yellow circle should be considered as the 18.84.

Given:

Principal = $50

Rate of simple interest = 6%

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for simple interest:

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Where, P is principal, r is the rate of interest in percentage and t is the number of years.

Putting [tex]P=50,\ r=6,\ t=3[/tex] in the above formula, we get

[tex]I=\dfrac{50\times 6\times 3}{100}[/tex]

[tex]I=\dfrac{900}{100}[/tex]

[tex]I=9[/tex]

Formula for amount is:

[tex]A=P+I[/tex]

Where, P is principal and I is the simple interest.

Putting [tex]P=50,\ I=9[/tex], we get

[tex]A=50+9[/tex]

[tex]A=59[/tex]

Therefore, the correct option is B.

The length of the hypotenuse in a right triangle is 12 inches.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given that, the lengths of the legs of a right triangle are 8 inches and 9 inches.

Let the length of the hypotenuse be x.

Here, x²=8²+9²

x²=64+81

x²=145

x=√145

x=12.04

x≈12 inches

Therefore, the length of the hypotenuse is 12 inches.

I hope this helps

Answer:

20

Step-by-step explanation:

Call the number you're trying to find  n.

"What" becomes  n.

n - 9 = 11

To "undo" the subtraction and reveal the value of  n ,  ADD 9 to both sides of the equation.  (Addition is the inverse operation of subtraction.)

n = 11 + 9 = 20
