Answer:

Value of z = 7

Value of y = 30

Step-by-step explanation:

We are given the following equations in the question:

$y = 9 + 3z\\y = 65 -5z$

We have to solve the given equation for y and z.

Equating the two equations we get,

$y = 9 + 3z\\y = 65 -5z\\9 + 3z = 65-5z\\3z + 5z = 65-9\\8z = 56\\\\z = 7\\y = 9+3(7) = 30$

Value of z = 7

Value of y = 30

Solve for x. Round to the nearest hundredth.

zlopas [31]

<u>Given </u>that the length of the hypotenuse is 8 and the angle is 42°

The length of the one leg of the triangle is x.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trigonometric ratio.

Thus, we have;

$sin \ \theta=\frac{opp}{hyp}$

Substituting the values, we get;

$sin \ 42^{\circ}=\frac{x}{8}$

Multiplying both sides of the equation by 8, we get;

$sin \ 42^{\circ}\times8=x$

Simplifying, we get;

$0.669 \times 8=x$

$5.352\approx x$

Therefore, the value of x is 5.35(app.)

Hence, Option A is the correct answer.

Answer:

third option

Step-by-step explanation:

time ('x') is the independent variable so that leaves only options 1 and 3 as the answer

is the slope equal to 0.6 or 1.8?

I used the slope formula with the following points: (1,2) and (5,9)

(9-2) / (5-1) = 7/4 = 1.75, or 1.8

If the radius is 18 cm and the angle at centre of circle is 120° then the

PolarNik [594]

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

$\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }$

Given that;

Radius r = 18 cm
Angle θ = 120°

Then. the area of the sector can be calculated as:

$\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }$

$\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }$

A = 339.336 cm²
