Answer:
Step-by-step explanation:
Remark
The diameter is 28 cm
Formula
Area = pi * r^2
Givens
pi = 22/7
r = d/2
r = 28/2
r = 14
Area = 22/7 * 14 * 14
Area = 22 * 2 * 14
Area = 44 * 14
Area = 616
If 100 soldiers can eat 100 dozen rations in a week, how long will it take 400 soldiers to eat 400 dozen rations?
Answer:
1 week
Step-by-step explanation:
100 soldiers / 100 dozen = 1 soldier / 1 dozen
400 soldiers / 400 dozen = 1 soldier / 1 dozen
Therefore, it also takes a week for 400 soldiers to eat 400 dozen rations

Step-by-step explanation:
Saul makes Apple Green paint and Citron Green paint.
He mixes green paint with white paint as shown.
Apple Green
green : white = 2:1
Citron Green
green : white = 4:5
He makes 90 litres of Apple Green paint.
To this Apple Green paint he adds 24 litres of green paint.
How much more white paint does he need to add to make Citron Green paint?
Your final line must say, He needs to add ... litres of white paint.
Answer:
You would need 18 litres more of white paint to create Citron Green paint.
Step-by-step explanation:
Given the Green Apple paint contains 24 litres of green paint in a 2:1 ratio with white paint, we can conclude the mixture contains 12 litres of white paint because 24 / 2 = 12.
In a Citron Green paint mixture, the current paint mixture would contain 24 litres of green paint in a 4:5 ratio with white paint. This would mean there are 30 litres of white paint in this mixture.
24 / 4 = 6
5 x 6 = 30
To make Citron Green paint, you would need 18 litres more of white paint.
30 - 12 = 18
The amount of white paint that needs to be added is required.
He needs to add 75 liters of white paint.
RatiosLet x be amount of green paint
y be amount of white paint.
Amount of apple green paint is 90 L, so
[tex]x+y=90[/tex]
The ratio of green to white paint is 2:1, so
[tex]\dfrac{x}{y}=\dfrac{2}{1}[/tex]
Rearranging the equation
[tex]x=2y[/tex]
Substituting in the first equation
[tex]2y+y=90\\\Rightarrow y=\dfrac{90}{3}\\\Rightarrow y=30\ \text{L}[/tex]
Amount of white paint is 30 L.
Amount of green paint is [tex]x=2y=2\times 30=60\ \text{L}[/tex]
Amount of green paint added to the apple green paint is 24 L.
Amount of green paint in the mixture is 60+24 = 84 L.
Let the amount of white paint to be added in the mixture be y.
This will be added to the 30 L of white paint in the original mixture.
The ratio of green:white = 4:5, so
[tex]\dfrac{84}{y+30}=\dfrac{4}{5}\\\Rightarrow \dfrac{84\times 5}{4}=y+30\\\Rightarrow 105=y+30\\\Rightarrow y=105-30=75[/tex]
The amount of white paint to be added is 75 L.

5. The table below represents a quadratic function: draw a graph plot points
What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?
Answer:
The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Solve the inequality 3x – 8 > 16
Answer:
x is greater than 8
Step-by-step explanation:
3x-8>16
3x>24
x>8
The solution of the inequality is : x is greater than 8.
Here, we have,
given that,
the inequality 3x – 8 > 16
now, we have to Solve the inequality 3x – 8 > 16
so, we get,
3x-8>16
adding 8 on both side, we get,
=>3x>24
dividing both side by 3, we get,
=>x>8

Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
x = 36, the measure of the angle is 72
Step-by-step explanation:
We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.
2x = 72
[tex]\frac{2x}{2}[/tex] = [tex]\frac{72}{2}[/tex]
x = 36
LMNP is rotated 180° clockwise around the origin.
Answer:
The correct answer is B
Step-by-step explanation:
-3,-4
Coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.
What is clockwise rotation?
" Clockwise rotation means when any object is moving in the direction of hands of clock."
According to the question,
As per the diagram ,
Coordinates of M are ( 3, 4)
Rotation of a point through 180° about the origin when a point M( x, y) is rotated about the origin through 180° in anticlockwise or clockwise direction, it takes the new coordinates ( -x ,-y).
Therefore , coordinates of M are ( -3, -4).
Hence, coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

B. (1, 1), (2, 2), (3, 3), (4, 4). (5, 8). C. ( 2, 7), (6,5), (4.4), (3, 3), (2, 1)
D. (9. -3), (19, 3) (4, -2), (4, 2), (0, 0)
Answer:
A
Step-by-step explanation:
A function is a relationship between inputs where each input is related to exactly one output.
A function can be one-to-one and many-to-one but can not be one-to-many.
The relation that is a function is
(1, 1), (2, 2), (3, 3), (4, 4). (5, 8). C. ( 2, 7),
Option B is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A function can be one-to-one and many-to-one but can not be one-to-many.
A. (1, 0), (3.0), (1.1), (3, 1) (1.3)
This is not a function because we have one-to-many.
(1, 0) and (1, 1) are one-to-many.
B. (1, 1), (2, 2), (3, 3), (4, 4). (5, 8).
This is a function because it satisfies the function.
The given relation are one-to-one.
C. ( 2, 7), (6,5), (4.4), (3, 3), (2, 1)
This is not a function because we have one-to-many.
(2, 7) and (2, 1) are one-to-many relations.
D. (9. -3), (19, 3) (4, -2), (4, 2), (0, 0)
This is not a function because we have one-to-many relations.
(4, -2) and (4, 2) are one-to-many relations.
Thus,
The relation that is a function is
(1, 1), (2, 2), (3, 3), (4, 4). (5, 8). C. ( 2, 7),
Option B is the correct answer.
