Answer:
25%
Step-by-step explanation:
We can use a proportion to answer this question:
64 represent the 100% of the games
so:
x : 100 = 16 : 64
x = (16*100)/64 = 1600/64 = 25%
A square is attached to a semicircle to make the figure shown in the diagram below .
if the radius of the semicircle is 4 meters ,what is the aproximate area of the figure .
Answer:
C) 89.12 m^2
Step-by-step explanation:
You can find the area of this figure by finding the areas of both shapes (semicircle and rectangle) then adding both areas.
To find the area of a semicircle, use this formula:
1/2πr^2 (1/2 x 3.14 x radius x radius)
Here, this radius is 4.
Now, we just plug in the numbers.
[3.14 is always used for π (pi)].
1/2 x 3.14 x radius x radius
↓
1/2 x 3.14 x 4 x 4 = 25.12
25.12 is the area of the semicircle.
Now, we must find the area of the square.
SQUARES ARE HAVE EQUAL SIDES, SO TO FIND THE AREA, WE SIMPLY MULTIPLY A SIDE LENGTH BY ITSELF TWICE.
8 x 8 = 64.
Now that we have both areas, we add to find the area of the figure.
25.12 + 64 = 89.12
Therefore, the area of this figure is 89.12 meters^2.
find the radius, diameter, circumference, and area of this circle.
Answer:
Area of circle = 28.28 unit²
Radius of circle from center point = 3 units
Diameter of given circle = 6 units
Circumference of circle = 18.85 unit
Step-by-step explanation:
Given:
Circle in third quadrant
Radius of circle from center point = 3 units
Diameter of a circle = 2 x Radius of circle
Diameter of given circle = 2 x Radius of circle from center point
Diameter of given circle = 2 x 3 units
Diameter of given circle = 6 units
Circumference of circle = 2πr
Circumference of circle = 2(22/7)(3)
Circumference of circle = 18.85 unit
Area of circle = πr²
Area of circle = (22/7)(3)²
Area of circle = 28.28 unit²
For males in a certain town, the systolic blood pressure is normally distributed with a
mean of 105 and a standard deviation of 9. What is the probability that a randomly
selected male's systolic blood pressure will be less than 100, to the nearest
thousandth?
Answer:
Suppose those rental rates have approximately a normal distribution, with a standard deviation of. $150. ... Canada, systolic blood pressure readings have a mean of 121 and a standard deviation of 16. A reading.
Probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
According to the question
For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 9.
Probability that a randomly selected male's systolic blood pressure will be less than 100
P(x < 100)
By using normalized normal distribution
= [tex]N(\frac{100-105}{9} )[/tex]
= [tex]N(\frac{-5}{9} )[/tex]
We have N(-a) = 1 - N(a), a>0
= 1 - [tex]N(\frac{-5}{9} )[/tex]
= 1 - N(0.556)
= 1 - 0.6026
= 0.3979
≈ 0.397 (nearest thousandth)
So, probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.

Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3, 0), H(2, -3) is a rectangle
Answer:
Quadrilateral MATH is a rectangle
Step-by-step explanation:
Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3, 0), H(2, -3) is a rectangle
A rectangle is a quadrilateral whose opposite sides have the same lengths and are parallel.
We solve the above question using the formula below to find the length of its sides
= √(x2 - x1)² + (y2 - y1)² when we are given vertices(x1, y1) and (x2, y2)
For side MA
M (-4,-1) A(-3,2)
√(-3 - (-4))² + (2 - (-1))²
= √1² + 3²
= √1 + 9
= √10 units
For side AT
A(-3,2). T(3, 0)
√(3 - (-3))² + (0 - 2)²
= √6² + -2²
= √36 + 4
= √ 40 units
For side TH
T(3, 0), H(2, -3)
√(2 - 3)² + (-3 - 0)²
√-1² + -3²
= √1 + 9
= √10 units
For side MH
M (-4,-1) H(2, -3)
√(2 - (-4))² + (-3 - (-1))²
= √6² + 2²
= √36 + 4
= √40 units
From the above calculation, we can see that
Side MA = Side TH = √10 units
Side AT = Side MH = √40 units
Opposite sides are parallel to each other, hence quadrilateral MATH is a rectangle

On a given day, eight rabbits, 12 mice, and four snakes are present on the mountain range. If each animal is equally likely to be caught and consumed, what is the probability that the wolf will eat two rabbits?
Answer:
7 / 69
Step-by-step explanation:
Rabbit = 8
Mice = 12
Snake = 4
Total = (8 + 12 + 4) = 24
If each animal has equal probability of being caught ;
Probability of catching a rabbit ;
Number of rabbits / total number of animals
P(catching 1 rabbit) = 8 / 24 = 1/3
P(catching 2nd rabbit) :
Number of rabbits left = 8 - 1 = 7
Total number of rabbits = 24 - 1 = 23
Hence, P(catching 2nd rabbit) = 7 /23
Probability of catching two rabbits :
1 /3 * 7/ 23 = 7 / 69

Answer:
yes
because it has length, side and base
Answer:
No
Step-by-step explanation:
If it is a right angled triangle, then it will satisfy the pythagoras theorem, which is as follows:
Perpendicular² + Base² = Hypotenuse²
{hypotenuse is the longest side in a right-angled triangle}
LHS : Perpendicular² + Base²
(15)² + (10)² = 225 + 100 = 325
RHS : Hypotenuse²
(17)² = 289
LHS ≠ RHS
Does not satisfy pythagoras theorem
So the triangle is not right angled

So the only we have is the measurement of angle H, which is 49°. So we're going to assume that they're all equal, cause I don't know what else to do, so:
180° - 49° = 131°
So, I think that angle F is 131°

Greatest common factor of c and c: c
Common factor: 12c
36a^5bc / 12c = 3a^5b

A rectangle has a length of (3x - 4) units and a width of (2x + 3) units. What is the perimeter of the rectangle in terms of x?
Answer:
(10x-2) units
Step-by-step explanation:
The perimeter of a rectangle is 2*length+2*width.
2(3x-4)+2(2x+3)
=6x-8+4x+6
=10x-2
The perimeter of a rectangle is ( 10x - 2 ).
Here,
The length of rectangle is (3x - 4) units.
The width of rectangle is (2x + 3) units
We have to find the perimeter of a rectangle.
What is the perimeter of a rectangle?
The sum of two times of length and width is called the perimeter of a rectangle.
Now,
The length of rectangle is (3x - 4) units.
The width of rectangle is (2x + 3) units
Since, The perimeter of a rectangle = 2 (length + width)
Hence, The perimeter of a rectangle = 2(3x - 4 + 2x + 3)
= 2 (5x -1)
= 10x - 2
Therefore, The perimeter of a rectangle is ( 10x - 2 ).

Use substitution to solve the
following system of equations.
9x + 5y = 32 AND y = -3x + 4
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10

IGNORE THE WRITING
Answer:
ANSWER BELOW
Step-by-step explanation:
If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
198 + 36 = 234 sq ft
