Find the area and circumference of each shaded sector. Use 3.14 for . Round to the
nearest tenth.
Answer:
Area = 226.1 ft^2
and circumference = 61.7 ft.
Both to the nearest tenth.
Step-by-step explanation:
The area of shaded part
= 1/2 *3.14 r^2
= 1/2 * 3.14 * 12^2 = 226.1 ft^2.
Circumferences of the shaded part = diameter + length of the semicircle
= 2 *r + 3.14 * r
= 2*12 + 3.14 * 12
= 61.68 ft.

Amari pays $7,440 in taxes on his income of $46,500. What percentage of his income is going toward taxes???
Answer:
16%
Step-by-step explanation:
percent = part/whole × 100%
percent = 7440/46500 × 100%
percent = 0.16 × 100%
percent = 16%
Answer:
Step-by-step explanation:
You divide 7,440 by 46,500 because that is the amount of his income going towards taxes.
7440/46500 = .16
.16=16%

Answer:
Axis of symmetry: x = 5
Vertex form: y = -4(x - 5)² + 3
Step-by-step explanation:
Given ordered pairs: (2, -33) (3, -13) (4, -1) (5, 3) (6, -1)
Axis of Symmetry
As this is a parabola, it will be symmetrical.
To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.
Two ordered pairs with the same y-value: (-4, 1) and (6, -1)
Midpoint of x = 4 and x = 6 is: x = 5
Therefore, the axis of symmetry is x = 5
Vertex form
Vertex form of a quadratic equation: y = a(x - h)² + k
(where (h, k) is the vertex)
The axis of symmetry is the x-value of the vertex of the parabola.
As we have been given the point when x = 5, the vertex is: (5, 3)
Substituting this into the formula:
⇒ y = a(x - 5)² + 3
To find the value of a, substitute any of the other points into the formula and solve for a.
Using (4, -1)
⇒ a(4 - 5)² + 3 = -1
⇒ a(-1)² = -4
⇒ a = -4
Therefore, the vertex form of the parabola is:
y = -4(x - 5)² + 3
You throw a baseball upward with an initial velocity of 35 feet per second. The height h (in feet) of the baseball relative to your glove is modeled by the position function
h(t) = −16t² + 35t,
where t is the time in seconds. How long does it take for the ball to reach your glove? (Round your answer to one decimal place.)
Answer:
35/16 sec ( 2 3/16 sec)
Step-by-step explanation:
This assumes you glove is at height = 0
0 = -16t^2 + 35t
0 = t ( -16t + 35) shows t = 0 ( before you throw it) and t = 35/16 sec
0.46 + (-0.642)
Please help!! Thank you!!
Answer:
-0.182
Step-by-step explanation:
Given expression:
0.46 + (-0.642)It should be noted that;
1. Positive integer + (Negative integer) = Positive integer - Positive integer
a + (-b) = a - b2. Positive integer - (Negative integer) = Positive integer + Positive integer
a - (-b) = a + bOur case is point 1. Therefore,
⇒ 0.46 + (-0.642)⇒ 0.46 - 0.642⇒ -0.182If you randomly select a letter from the phrase "Brandon loves to eat at Red Robin," what is the probability that you select a consonant? (Your answer must be in the form of a reduced fraction.)

8) Solve the exponential equation
Answer:
5/8 =x
Step-by-step explanation:
2 ^ ( 3x-5) = ( 1/32) ^x
Rewriting 1/32 as 2 ^ -5
2 ^ ( 3x-5) = ( 2^-5) ^x
We know that a^b^c = a^ ( b*c)
2 ^ ( 3x-5) = ( 2) ^-5x
Setting the exponents equal
3x-5 = -5x
Subtract 3x from each side
3x-5-3x = -5x-3x
-5 = -8x
Divide each side by -8
-5/-8 = -8x/-8
5/8 =x
Box A contains only 20-cent coins and Box B contains only 50-cent coins. The number of coins in Box A is twice the number of coins in Box B. The amount of money in Box B is $1.60 more than the amount of money in Box A. How many 20-cent coins are there in Box A?
Answer: There should be 16, 20 cent coins
Step-by-step explanation:
First we have to do 1.60 x 2 which equals 3.2
Then we divided by 0.20 because the equals the 20 cent coins
We get 16
We can check our work by 0.20 x 16 and that gives us 3.2

Don drew this diagram of four rectangular pens he wants to build for his four goats. If
each of the pens are 12 feet by 9 feet, how
many feet of fencing does he need?
(Will give brainliest if you show work)!
Answer:
So he will need 168 feet of fencing.
Step-by-step explanation:
The perimeter formula of a rectangle is P=(2xL)+(2xW)
The length is 12 and the width is 9.
First, do P=(2x12)+(2x9), P=24+18 P=42 feet
Next, since there are four pens multiply the perimeter of 1 pen by 4.
4x42=168 feet of fencing
So, Don will need 168 feet of fencing.

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
Let the area of the semicircle be S
Let the total area of the figure be T = S + A
where A = ( 4 )² = 16 cm²
And , S = ( πr² ) / 2
S = 3.14 x ( 2 )² / 2
S = 6.28 cm²
So , the total area T =6.28 cm² + 16 cm² = 22.28 cm²
Hence , the area of the figure is T = 22.28 cm²
