Answer:
18.84 in^2
Step-by-step explanation:
Area brother ate = 1/6 x area of pizza
a pizza is the shape of a circle. the area of a pizza is equal to the area of a circle
Area of a circle = πr²
r = 12/2 = 6
he diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter

1/6 x 113.04 = 18.84
Solve for b.
- 28 – 6b= 8
Answer:
-6
Step-by-step explanation:
- 28 – 6b= 8
step 1 add 28 to each side
-28 + 28 cancels out
28 + 8 = 36
we now have -6b = 36
step 2 divide each side by -6
-6b / -6 = b
36 / -6 = -6
we're left with b = -6

Here’s why:
We will have to preform inverse operations to solve for 'b'.

Answer:
A. 44/625
Step-by-step explanation:
There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.
11/25 x 4/25 = 44/625
Wich of the following equations would NOT contain the point (4,12)
Given:
The given point is (4,12).
To find:
The equation that would NOT contain the point (4,12).
Solution:
We need to check each equation for the point (4,12).
In option A, the given equation is:
[tex]y=-2x+20[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=-2(4)+20[/tex]
[tex]y=-8+20[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
In option B, the given equation is:
[tex]y=\dfrac{1}{2}x+8[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=\dfrac{1}{2}(4)+8[/tex]
[tex]y=2+8[/tex]
[tex]y=10[/tex]
This equation does not contain the point (4,12).
In option C, the given equation is:
[tex]y=-\dfrac{1}{2}x+14[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=-\dfrac{1}{2}(4)+14[/tex]
[tex]y=-2+14[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
In option D, the given equation is:
[tex]y=\dfrac{3}{4}x+9[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=\dfrac{3}{4}(4)+9[/tex]
[tex]y=3+9[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.
Hey!! Can any of y'all help me find the center and radius of this equation?
x^2+y^2-8x+2y=-8
Answer:
Center: (4,-2)
Radius: 2√3 units
Step-by-step explanation:
We wish to find the center and radius of the equation x²+y²-8x+2y=-8
Step 1: Complete the square for both variables:
x²+y²-8x+2y=-8
x²-8x+y²+2y=-8 (Rearrange)
x²-8x+16+y²+2y+4=-8+16+4 (Add to both sides)
(x-4)²+(y+2)²=12 (Reduce trinomials)
Step 2: Interpret the center and radius of the circle:
The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center of the circle and r is the radius of the circle. Since (h,k) translates to (4,-2), this means the center of the circle is (4,-2). Since r²=12, then r=√12=2√3 units

1/2,×5×945/222.5cm²stay safe healthy and happy..The city is planting new trees in its downtown to make the streets more comfortable for visitors. They are planting each tree 12 feet apart. How many trees can they plant on 2 miles of streets? Hint is that 5280= 1 mile. Please help
Step-by-step explanation:
let's make T= the number if trees...
If we're placing one tree every 12 feet for two miles, then:
T×(space between trees) = (number of miles)×(1mi.)
T×12ft. = 2×1mi. = 2×5280ft.
Dividing by 12ft. to isolate T gives us:
T=(2×5280)/12 = 880
So that'll be 880 trees for 2 miles of street.
The number of trees that they plant on 2 miles of streets will be 880 trees.
What is division?Division means the separation of something into different parts, sharing of something among different people, places, etc.
The city is planting new trees in its downtown to make the streets more comfortable for visitors.
They are planting each tree 12 feet apart.
Then the number of trees that they plant on 2 miles of streets will be
We know the conversion of miles into feet.
1 mile = 5280 feet
2 miles = 10560 feet
Then the number of trees will be
Number of trees = 10560 / 12
Number of trees = 880

Seth’s bank charges $5 a month to maintain a checking account and $0.50 for each check Seth writes. Last month, Seth paid a total of $6.50 in checking account fees. How many checks did he write?
A 1 C 3
B 2 D 4
Answer:
13
Step-by-step explanation:
Since Seth pays $0.50 for each check he writes, he would write (let x be how many checks Seth wrote) "x" checks for $6.50. That means;
1 = 0.50
x = 6.50
Now let us set up a fraction:
[tex]\frac{0.5}{1}=\frac{6.5}{x}[/tex]
Step 1: Cross multiply
[tex]0.5x=1\cdot \:6.5[/tex]
[tex]0.5x=6.5[/tex]
Step 2: Divide both sides by [tex]0.5[/tex]
[tex]\frac{0.5x}{0.5}=\frac{6.5}{0.5}[/tex]
Simplify
[tex]x=13[/tex]
Therefore, Seth will write 13 checks for $6.50
What is cos 30°? 60° 1 90° 30° V3 O A. v3 O B. 1 O c.
Answer:
E
Step-by-step explanation:
Cos=Adjacent/hypotenuse
Cos30=rad3/2
The cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2.
What are trigonometric functions?There are six major trigonometric functions as -
Sine(x)Cosine(x)Tangent(x)Cotangent(x)Secant(x)Cosecant(x)We can write the relation between them as -
Sine = 1/cosecantCosine = 1/secantTangent = 1/CotangentAlso the following trigonometry relations hold true -
sin²Ф + cos²Ф = 1
1 + tan²Ф = sec²Ф
1 + cot²Ф = cosec²Ф
Given is a right angled triangle as shown in the image having 60 - 90 - 30 orientation and the measured sides as shown in the image.
We can write the cosine function as -
cosФ = Base/Hypotenuse
cos(30) = √3/2
So, we can conclude that the cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2
Therefore, the cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2.
