Answer:

-√7/4

Step-by-step explanation:

Mathematically;

Sine is the ratio of opposite to hypotenuse

So here, hypotenuse is 4

The opposite is 3

To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides

Let the adjacent be x

4^2 = 3^2 + x^2

x^2 = 16-9

x^2 = 7

x = √7

The cosine is the ratio of the adjacent to the hypotenuse

Since we want to consider quadrant II

Cosine is negative here;

So the answer for Cos will be;

Cos theta = -√7/4

Answer:

He walks 1030 meters if he walks across the park.

Step-by-step explanation:

In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....

Let "c" be the distance he will need to walk if he was going to go through the park

Let "a" be the distance he walks on King Street

Let "b " be the distance he walks on Queen Street, then.....

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c = \sqrt{a^{2} + b^{2} }[/tex]

(Now plug in the values of a and b and get.....)

c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]

c = [tex]\sqrt{1060000 }[/tex]

c = 1029.563014............

So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

Answer:

Solve equation [2] for the variable y

[2] y = 8x + 7

// Plug this in for variable y in equation [1]

[1] 4x - 5•(8x+7) = -9

[1] -36x = 26

// Solve equation [1] for the variable x

[1] 36x = - 26

[1] x = - 13/18

// By now we know this much :

x = -13/18

y = 8x+7

// Use the x value to solve for y

y = 8(-13/18)+7 = 11/9

Solution :

{x,y} = {-13/18,11/9}

Answer: umm is there a picture?

Step-by-step explanation:

where is it? but sure

Step-by-step explanation:

we have,

general term = 2(1/2)^n-1

Now,

7th term (t7)= 2(1/2)^7-1

= 2(1/2)^6

=2(1/64)

=2/64

=1/32 #

Ans. = 1/32

Answer:

2x+4y

Step-by-step explanation:

( 1 /4 )(8x+16y)

Distribute

( 1 /4 )(8x)+( 1 /4 )(16y)

=2x+4y

Answer:

Step-by-step explanation:

Given system of equations is,

8x + 10y = 120 -----(1)

x - y = -3 ------(2)

From the second equation,

x = y - 3 [Option A]

Now we substitute the value of x in equation (1) and solve for y,

8(y - 3) + 10y = 120

8y - 24 + 10y = 120

18y = 120 - 24

y = [tex]\frac{96}{18}[/tex] = 8

From equation (2)

x - 8 = -3

x = 8 - 3

x = 5

Proportional equations are the equations that have the graph which pass through (0,0).

y = -9x is proportional.

y=x is proportional

y=1/2x is proportional

That's it. Only these three equations have (0,0) intercept.

Answer: 1 1/5

Step-by-step explanation:

Answer:

Mixed number- 1 and 1/5

Fraction- 12/10

Step-by-step explanation:

1.2 is read as 1 and 2 tenths. 1 and 2 tenths is the same as 1 and 2/10.

1 and 2/10 in simplest from is 1 and 1/5.

1 and 1/5 can also be written as 12/10.

1: 60 - 25% = 45 minutes

2: 60 - 75% = 15 minutes

Answer:

15 minutes because 25 percent goes in 4 times to 100 so 60 divided by 4 is 15

45 minutes because 75 percent goes in 3 times to 100 and 15x3 is 45

Answer:

The value of a is 15.

Step-by-step explanation:

First, you have to find the total interior angles of the polygon using the formula, sum = (n-2)×180°, where n represents the number of sides :

sum = (n-2)×180°

sum = (5-2)×180°

sum = 540°

Given that the sum of the interior angle is 540° so in order to find the value of a, you have to add up all the angles in terms of a :

3a + 150 + 8a + 6a + 9a = 540

26a + 150 = 540

26a = 390

a = 390 ÷ 26

a = 15

Answer:

x = 4

Step-by-step explanation:

5x + 2 and 4x + 6 are alternate angles and are congruent, thus

5x + 2 = 4x + 6 ( subtract 4x from both sides )

x + 2 = 6 ( subtract 2 from both sides )

x = 4
