How much of the circle is shaded? Write your answer as a fraction in simplest form? 3/7 and 1/3 isn't shaded
Answer:
[tex]total = 1 \\ \frac{1}{2} + \frac{1}{7} + x = 1 \\ \frac{1}{7} + x = 1 - \frac{1}{2} \\ \frac{1}{7} + x = \frac{1}{2} \\ x = \frac{1}{2} - \frac{1}{7} \\ x = \frac{7 - 2}{7 \times 2} \\ x = \frac{5}{14} \\ \\ shaded \: portin \: = \frac{5}{14} \\ thank \: you[/tex]
Answer:
[tex]\frac{5}{14}[/tex]
Step-by-step explanation:
Half the circle ( to the left ) is partly shaded
shaded part = [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{7}[/tex] = [tex]\frac{7}{14}[/tex] - [tex]\frac{2}{14}[/tex] = [tex]\frac{5}{14}[/tex]

Part 2: Graph the image of the figure using the transformation given. Don't forget to prime marks on your new image.
4. Reflection across the y-axis
Answer:
F' = (2 , -4)
G' = (-1 , -3)
H' = (4 , 0)
I' = (5 , -2)
Step-by-step explanation:
To get the coordinate points of a figure that is reflected across the y-axis, perform the following action to each point:
(x , y) → (-x , y)
Using this will give the points of F', G', H', and I'.
To find the new points, plug in the values into the formula:
F → F' = (-2 , -4) → (2 , -4)
G → G' = (1 , -3) → (-1 , -3)
H → H' = (-4 , 0) → (4 , 0)
I → I' = (-5 , -2) → (5 , -2)
To graph the new figure, plot the new points and connect them. At each point, remember to label them with the corresponding letter as well as the ' symbol.
Solve T=2x + 3y - z for y.
Answer:
[tex]\frac{T+z-2x}{3}[/tex]=y
Step-by-step explanation:
On solving for y we get -
[tex]$y=\frac{T-2x+z}{3}[/tex]
We have the following expression -
T = 2x + 3y - z
We have to solve for ' y '.
Solve for x : Sin([tex]2n\pi x[/tex]) = 0.785 .On solving, we get -
Sin([tex]2n\pi x[/tex]) = 0.785
Sin([tex]2n\pi x[/tex]) = Sin ([tex]\frac{\pi }{4}[/tex])
2n[tex]\pi[/tex]x = [tex]\frac{\pi }{4}[/tex]
x = [tex]\frac{1}{8n}[/tex]
According to the question, we have -
T = 2x + 3y - z
T - 2x + z = 3y
[tex]$y=\frac{T-2x+z}{3}[/tex]
Hence, on solving for y we get -
[tex]$y=\frac{T-2x+z}{3}[/tex]

counts 3 more. What patterns do you notice in
the numbers Jordan counts?
50 51 52 53 54 55 56 57 58 59 60
Answer:
Step-by-step explanation:
goes up by 1 each time
The pattern of Jordan is that, she goes up by 1 , each time.
It is given that Jordan counts 53 ducks on a pond and then she counts 3 more by following a same pattern each time.
What is the pattern that she follows ?
What will be the value if we add 1 for 4 times.
The value will be 4.
The numbers Jordan counts are
50, 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59, 60
If we check
51 - 50 = 1
52-51= 1
.
.
.
60-59 = 1
and so on.
Every time we get a difference of 1 count.
Thus , the pattern followed by Jordan is that, she goes up by 1 , each time.

Rick and tom share a reward of $75 in a ratio of 2:3. how much money does each of them get?
Answer:
Rick gets $30 and Tom gets $45.
Step-by-step explanation:
If Rick gets 2 parts, and Tom gets 3 parts, then there are 5 parts. If $75 is split into 5 parts, each part will be worth $15.
Hence,
Rick gets 2 * $15 = $30
Tom gets 3 * $15 = $45
1. Find the equation of a parabola with a focus of (0, -6) and directrix y = 6.
Max points
9514 1404 393
Answer:
(d) y = -1/24x² (b) y = 1/36x²Step-by-step explanation:
1. The point halfway between the focus and directrix is the origin. That is, the vertex of the parabola is the origin. Then its equation can be written ...
y = 1/(4p)x²
where p is the distance from the vertex (origin) to the focus. Here, that distance is -6, so 4p = -24 and the parabola's equation is ...
y = -1/24x²
__
2. Same deal. The vertex is the origin, but this time the focus is above the origin by 9 units. Then the equation is ...
y = 1/36x²

The Campbells are saving up to go on a family vacation in 5 years. They invest $2800
into an account with an annual interest rate of 1.46% compounded monthly. Assuming no withdrawals are made, how much money is in the Campbells' account after 5 years?
Answer:
look at the explanation 20,440
Step-by-step explanation:
so the invested 2,800 $ and the interest rate is 1.46 so first what I would do is 1.46 times 5 = 7.3 then 7.3 x 2,800 =20,440
so I think the answer is 20,440
not sure if this is correct but I gave it my all
or you could just do 2800 time 5 time 1.46

Mao counts by fives to 30.alana counts by tens to 40.who will say more numbers? Explain
Answer:
Mao will say more numbers
Step-by-step explanation:
Mao will say more numbers because, to get to 30, you must count by fives 6 times. For example, 5,10,15,20,25,30. There are 6 numbers there. On the contrary, Alana is only going to count 4 times. 10,20,30,40. 6 is greater than 4, therefore Mao will say more numbers. I hope this helps!
