If the wheel has six piece and the goal is to get anything 4 and under there is 2/3 chance that you will get that number.
Alan made $396 for 18 hours of work. At the same rate, how much would he make for 11 hours of work?
Answer:
Step-by-step explanation:
I think it is helpful to set this up as a proportion as it is the easiest way in my opinion.
1st step: 396/18 and x/11
This is the way you set up the proportion.
2nd Step: You would have to multiply 396 and 11 then divide the value by 18.
396x11 = 4,356
4,356/18 = 242
x=242 Dollars
Answer: 242 dollars
Therefore, Alan would make 242$ while working at the same rate for 11 hours.

the area is ___ square units
Answer:
392 square units
Step-by-step explanation:
We can make 2 right trapezoids out of this shape.
The area of a trapezoid would be 1/2×(b1+b2)×h or (b1+b2)×h ÷ 2.
If we do 1 half it would be 1/2×(14+14)×14 = 196
Now if we multiply by 2 (because we have 2 trapezoids) it would be 392.

A parabola can be drawn given a focus of (4, -8) and a directrix of y=-6
. What can be said about the parabola?
Answer:
y = 1/4 (x-4)² - 7
Step-by-step explanation:
Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
√(x-4)²+(y- -8)² = √(y- -6)²
(x-4)² + (y+8)² = (y+6)²
(y+8)² - (y+6)² = (x-4)²
(y²+16y+64) - (y²+12y+36) = (x-4)²
y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
4y = (x-4)² - 28
y = 1/4 (x-4)² - 7
standard formula of parabola: y = a(x-h)² + k (h,k): vertex (4,-7)
The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
Now,
Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
Hence, We can formulate;
⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²
⇒ (x-4)² + (y+8)² = (y+6)²
⇒ (y+8)² - (y+6)² = (x-4)²
⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²
⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
⇒ 4y = (x-4)² - 28
⇒ y = 1/4 (x-4)² - 7
Thus, The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7

Answer:
[tex]\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}[/tex]
Step-by-step explanation:
if [tex]\sec x = \frac{4}{3}[/tex], then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.
The other leg (specifically the opposite one) will be equal to [tex]\sqrt{16-9} = \sqrt{7}[/tex] by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = [tex]\frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}[/tex].
cot(x) is defined as adjacent over opposite, which is equal to [tex]\frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}[/tex]
That means that the first option, the leftmost one, is correct.
The compact disc format has been declining in popularity, and one music executive has predicted that CD sales will decrease by 20% per year. If the executive's company sold 29,000,000 CDs this year, how many will the company sell 9 years from now?
Answer: 3,892,314 CDs
Step-by-step explanation:
You can find this using the future value formula:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = 29,000,000
Rate = -20% because it is decreasing
Number of years = 9
CDs sold in 9 years will therefore be:
= 29,000,000 * ( 1 - 20%) ⁹
= 3,892,314 CDs

Find the measure of the indicated arc
Answer:
m[tex]\widehat{WXY}[/tex] is 224°
Step-by-step explanation:
From the figure, we have;
The angle subtended at the circumference, by the arc mWXY, C = 112°
The angle subtended at the center = m[tex]\widehat{WXY}[/tex]
By circle theory, we have;
The angle subtended at the center = 2 × The angle subtended at the circumference
∴ m[tex]\widehat{WXY}[/tex] = 2 × 112° = 224°
m[tex]\widehat{WXY}[/tex] = 224°.

Answer:
I'll do the dilation for the first point and you will see the answer (please verify the second point)
Step-by-step explanation:
The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.
so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.
so the dilated point for (-4,-4) is (-14, -14)
Please verify by computing the dilated point for (-6,4)
