Answer:

sin(\theta)=\frac{5}{13}

Step-by-step explanation:

step 1

Find the hypotenuse of the right triangle with legs of 5 ft and 12 ft

Applying the Pythagoras Theorem

Let

d ----> the length of the hypotenuse

d^{2}=12^2+5^2

d^{2}=169

d=13\ ft

step 2

Find the sine of angle theta

Remember that

The sine of angle theta is equal to divide the opposite side of angle theta (5 feet) by the hypotenuse (13 feet)

sin(\theta)=\frac{5}{13}

Which is the most efficient first step to solve for x in the equation 3.7 x minus 18 = negative 4.3 x minus 34? Add 3.7x to both
ahrayia [7]

Answer:Add 4.3x to both sides of the equation.

Step-by-step explanation:

The given equation is expressed as

3.7x - 18 = - 4.3x - 34

The main aim is to solve for x and x is on the left hand side and the right hand side of the equation. So the most efficient step would be to make all the terms containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation.

Therefore, the most efficient first step to solve for x in the equation would be

Add 4.3x to both sides of the equation.

Solve the inequality -2x < 5, illustrating your solution on a number line.
Over [174]

Answer:

No.

Step-by-step explanation:

Let's first and try to isolate x.

-2x < 5

(Divide by -2)

x > -5/2 ( < changes to > b/c it was divided by a negative)

x > -2.5

Since x is all values greater than -2.5, -6 is not within those bounds.

Thus, -6 is not a solution to the inequality.

Hope that helps!

The system of equations x + 2y = 6 and x – 4y = 0 is graphed below. What is the solution to the system of equations?
blagie [28]

Step-by-step explanation:

x + 2y = 6....(1) \\  \\  x - 4y = 0\\ \implies \: x = 4y....(2)\\  \\ from \: equations \: (1) \: and \: (2) \\ 4y + 2y = 6 \\   \therefore \: 6y = 6 \\  \\ \therefore \: y =  \frac{6}{6}  \\  \\  \huge \red{ \boxed{ \therefore \: y =  1}} \\  \\ substituting \: y = 1 \: in \: equation \: (2) \\  \\ x = 4y \\  \\ \therefore \: x = 4 \times 1 \\  \\  \huge \orange{ \boxed{\therefore \: x = 4 }} \\  \\ \therefore \: (x, \:  \: y) = (4, \:  \: 1) \\ is \: the \: required \: solution. \\
