Please help I'm really confused I need have with these 6 questions

Ahh, basic shapes. Split up the weird shapes into easier ones. #1 can be truned into 2 trapezoids. #2 can be turned into 2 circles. #3 is a triangle and a trapezoid. #4 is 2 right triangles. #5 is a rectangel and a traingle. Finally, #6 is 3 traigles and a rectangle. Do you see how we broke the hard shapes into easier shapes?

There is a spinner with 9 equal areas, numbered 1 through 9. If the spinner is spun one time, what is the probability that the r

tangare [24]

Answer:

If we think of the numbers 1 through nine, only 1 of those numbers is a multiple of 2 AND 3 and that number is 6.

So, basically, the question is asking what is the probability that "6" will appear. That is a one out of 9 probability or 1/9 or 11.11%

Kristin graphed the locations of several places in her school on the coordinate plane shown below. Determine if each statement a

wel

Answer:

Step-by-step explanation:

1). Coordinates of Art → (1, -5).

Coordinates of Library → (1, 9)

Coordinates of Science → (-5, -5)

Distance between Art and Library = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(1-1)^2+(9+5)^2}$

= 14 units

Distance between Art and Science = $\sqrt{(1+5)^2+(-5+5)^2}$

= 6 units

Since 14 > 6,

Art is closer to Science than Library.

Answer is False.

2). Coordinates of Cafeteria → (-7, 9)

True.

The terminal side of an angle in standard position passes through P(15, –8). What is the value of sine theta? sine theta = fifte

Pavlova-9 [17]

The value of sine theta = negative eight-seventeenths ⇒ 2nd

Step-by-step explanation:

Let us revise the quadrant of an angle its terminal side passes through a given point

If the given point is (x , y), then the angle lies in the 1st quadrant
If the given point is (-x , y), then the angle lies in the 2nd quadrant
If the given point is (-x , -y), then the angle lies in the 3rd quadrant
If the given point is (x , -y), then the angle lies in the 4th quadrant

∵ The terminal side of angle Ф passes through P (15 , -8)

∵ x = 15 and y = -8

- P is (x , -y), then the angle Ф lies in the 4th quadrant

∵ The terminal side of angle Ф is the hypotenuse of a right

triangle whose horizontal leg is 15 units and vertical leg

is -8 units

- Use Pythagoras Theorem to find the length of the hypotenuse

∴ Hypotenuse = $\sqrt{(15)^{2}+(-8)^{2}}=17$ units

∵ sinФ = $\frac{opposite}{hypotenuse}$

∵ The side opposite to Ф is -8

∵ The hypotenuse is 17

∴ sinФ = $\frac{-8}{17}$

The value of sine theta = negative eight-seventeenths
