Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]

[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]

[tex]8\sqrt{3}=x[/tex]

And,

[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{16}{2}=y[/tex]

[tex]8=y[/tex]

Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].

Step-by-step explanation:

[tex]{:}\hookrightarrow\sf \dfrac {1}{4}\div \dfrac {9}{10}[/tex]

[tex]{:}\hookrightarrow\sf \dfrac {1}{4}\times \dfrac {10}{9}[/tex]

[tex]{:}\hookrightarrow\sf \dfrac {10}{36}[/tex]

[tex]{:}\hookrightarrow\sf \dfrac {5}{18}[/tex]

Answer:

$16

Step-by-step explanation:

60 + 4 = 64

64 ÷ 4 = 16

CHECK:

16 x 4 = 64

64 - 4 = 60

This is because 65/13 = 5 when using a calculator or long division. There are no fractional or decimal parts to the result 5, so 5 is an integer.

Something like 86/6 = 14.333 approximately showing the result is not an integer. The same applies to choice C and choice D as well.

HELP ME I GOT THE SAME QUESTION AND I'M DUMB :(

Step-by-step explanation:

Answer:

[tex]k = -\frac{1}{5}[/tex] -- Constant

[tex]y = -\frac{x}{5}[/tex] -- Equation

Step-by-step explanation:

Given

[tex]\{(-15, 3), (-5, 1), (0, 0), (10, -2)\}[/tex]

Solving (a): The constant of variation

The given parameter is of the form (x,y) and the variation constant is calculated using:

[tex]k = \frac{y}{x}[/tex]

For:(-15,3), k is calculated as

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{3}{-15}[/tex]

[tex]k = -\frac{1}{5}[/tex]

For (-5,1)

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{1}{-5}[/tex]

[tex]k = -\frac{1}{5}[/tex]

The equation is calculated using the following rule:

[tex]y = kx[/tex]

Substitute [tex]-\frac{1}{5}[/tex] for k

[tex]y = -\frac{1}{5} * x[/tex]

[tex]y = -\frac{x}{5}[/tex]

Answer:

25 - 3x = 40            ​x=-5

1/3x - 12 = -3           x=27

Step-by-step explanation:

25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -5

Answer:

$355

Step-by-step explanation:

85+60+35=180

5% of 3,500 is 175

175+180=355

so if i did the math right that means the answer is $355

Hopefully the right answer

Answer:

the answer is 12 :)))))

Answer: (t,u) -> (t-3, u+8)

Step-by-step explanation: Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

Answer:

33/40

Step-by-step explanation:

cross multiply

5 x 5 = 25

8 x 1 = 8

25 + 8 = 33 (our numerator)

8 x 5 = 40 (our least common denominator)

Answer:

there are 3 girls and 4 boys in the family. The girl has 3 sisters and 3 brothers.

Step-by-step explanation:

If there are 4 girls and 3 boys than the girl has 3 sisters and 3 brothers.

the boy has 4 sisters and 2 brothers. 2 is half of 4.

The value of x=2 and y=1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x+2y=8

5x+2y=12

Now, solving both using method of Elimination Method

3x - 5x = 8-12

-2x= -4

x = -4/ -2

x= 2

and, 3x+ 2y = 8

3(2) + 2y = 8

6  + 2y = 8

2y = 8-6

2y = 2

y = 2/2

y= 1

Hence, the value of x=2 and y=1.
