Answer:
height = 6 cm
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )
Here V = 100.48 and r = 4, thus
[tex]\frac{1}{3}[/tex]π × 4²h = 100.48
Multiply both sides by 3 to clear the fraction
3.14 × 16h = 301.44 ( divide both sides by 3.14 × 16 )
h = [tex]\frac{301,44}{3.14(16)}[/tex] = 6 cm

Denise went bowling with her friends at AMF. She paid $3 to rent shoes and then $4.75 for each game of bowling. If she spent a total of $22, then how many games did Denise bowl?
Answer: 4 games
Step-by-step explanation:
Whether Denise bowls or not, he incurs rent for bowling shoes and per bowling he has to pay $4.75 while he rented shoes for $3.
Then the equation is:
y = 3 + 4.75x
Where
y is the total cost
x is Number of bowling
y = 3 + 4.75x
3 + 4.75x = 22
4.75x = 22 - 3
4.75x = 19
x = 19/4.75
x = 4
Denise bowled 4 games.
Final answer:
To determine the number of games Denise bowled, an equation was set up using the cost of shoe rental and per game cost, and solved algebraically. Denise bowled 4 games.
Explanation:
The subject of this question is Mathematics, specifically focusing on simple algebra and solving equations. Denise's total expense for bowling is composed of a fixed cost for shoe rental and a variable cost for the games she played. The total cost is the sum of these two amounts. We can set up an equation to find out how many games she played:
Let x be the number of games Denise bowled. The cost of shoe rental is a fixed $3, and the cost per game is $4.75. So, the equation representing the total cost is:
3 + 4.75x = 22
Now, we will solve for x:
Subtract 3 from both sides of the equation:4.75x = 22 - 34.75x = 19Divide both sides by 4.75 to isolate x:x = 19 / 4.75x = 4Therefore, Denise bowled 4 games. This is a typical middle school algebra problem involving linear equations and is a good example of applying math skills to real-life situations such as budgeting and planning.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4
years; the standard deviation is 1.9 years.
arzo
Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a meerkat living between 12.3
and 14.2 years
PLEASE HELP
Answer:
13.5% probability of a meerkat living between 12.3 and 14.2 years.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 10.4
Standard deviation = 1.9
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above the mean.
Between 12.3 and 14.2 years.
12.3 = 10.4 + 1.9
So 12.3 is one standard deviation above the mean.
50% of the measures are above the mean. Of those, 68% are within 1 standard deviation of the mean.
14.2 = 10.4 + 2*1.9
So 14.2 is two standard deviations above the mean.
50% of the measures are above the mean. Of those, 95% are within 2 standard deviation of the mean.
0.5*0.95 - 0.5*0.68 = 0.135
13.5% probability of a meerkat living between 12.3 and 14.2 years.

The relationship between angles ∠a and ∠b is they are complementary angles.
Given a figure.
Here, two lines are crossed to each other such that the angles between each of the cross is 90 degrees.
So the angle between the lines BX and XC which forms at X is a right angle or 90 degrees.
So,
m∠BXC = 90°
Now, ∠BXC is the sum of the angles ∠BXY and ∠YXC.
From the figure,
∠BXY = ∠a and ∠YXC = ∠b.
So,
m∠BXY + m∠YXC = 90°
∠a + ∠b = 90°
When the sum of two angles is 90°, then they are complementary angles.
Hence, ∠a and ∠b are complementary angles, which is the option B.

What is the perimeter of ABC with vertices A(-2,9), B(7,-3), and C(-2,-3) and in the coordinate plain?
A. 21 units
B. 15 units
C. 34 units
D. 36 units
Answer:
Step-by-step explanation:
A - C = ( -2, 9) - (- 2 -3)
= ( 0, 12)
AC = 12
B - C = (7 - 3) - ( - 2 -3)
= (9, 0)
BC = 9
ABC is a right -angled triangle with AC as the hypotenuse
AC = sqrt( 9^2 + 12^2)
= sqrt(81 + 144)
= srqt(225)
= 15
Perimeter = 12 + 9 + 15
= 36 units
So the answer is 36 units
Answer:
36unitsStep-by-step explanation: A - C = ( -2, 9) - (- 2 -3)
= ( 0, 12)
AC = 12
B - C = (7 - 3) - ( - 2 -3)
= (9, 0)
BC = 9
ABC is a right -angled triangle with AC as the hypotenuse
AC = sqrt( 9^2 + 12^2)
= sqrt(81 + 144)

HOW TO DETERMINE SLOPE AND Y-INTERCEPT: Use the instructions below to answer this question.
EQUATION: y=[tex]\frac{-3}{4}[/tex]x-3
-------------------------------------------------
INSTRUCTIONS:FINDING THE Y-INTERCEPT:
Do this simply by finding the number your graph starts at on the Y-Axis (vertical line)! In this case, it's at -3!
FINDING SLOPE:
Remember that slope is rise over run ([tex]\frac{rise}{run}[/tex])
RISE = How far the line goes up and down.
RUN = How far the line goes left or right.
HOW DO I FIND IT? All you have to do is count both rise and run from one point on the line to another! WARNING: The point must hit at a vertex, it cannot be counted if it is in the center of the box, or anywhere that does not touch the edge. I also suggest starting from the Y-Intercept and counting.
GOING LEFT OR DOWN: This is a positive number
GOING RIGHT OR UP: This is a negative number.
(You will see how this applies, below, yayyyy)
CALCULATING OUR NUMERATOR, AKA RISE:
Starting from the y, to get to the next point on the line, you can see we have to go down three. This means our numerator is -3!
CALCULATING OUR DENOMENATOR, AKA RUN:
Starting from where we just stopped, we must continue getting to the next point, and to do that, you can see we have to go to the right four! This means our denomenator is 4!

2 cm on a map are equal to 3 km in real life. If two points
are 8 cm apart on the map, how far apart are they In real
life?
Answer: 12km
Step-by-step explanation:
2cm=3km
2x4=8
3x4=12
Final answer:
The real-life distance between two points that are 8 cm apart on a map, with a map scale of 2 cm = 3 km, is 12 km. This is calculated using a proportion based on the given scale ratio.
Explanation:
The question asks how to calculate the real-life distance between two points that are 8 cm apart on a map, given that 2 cm on the map are equal to 3 km in real life. To solve this, we can use a proportion where 2 cm on the map corresponds to 3 km of actual distance. The scale ratio is therefore 2 cm : 3 km. If the points are 8 cm apart on the map, we set up the proportion as follows:
2 cm on the map / 3 km in real life = 8 cm on the map / x km in real lifeWe cross multiply to find x:
2 cm * x km = 8 cm * 3 kmx = (8 cm * 3 km) / 2 cmx = 24 km / 2x = 12 kmSo, the real-life distance between the two points is 12 km.

A pizza with a diameter of 13 inches is cut into 12 equal slices. Jayden eats of the pizza, representing an area o Select one square inches. Carson eats 5 slices of pizza, representing an area of Select one square inches.
The complete question is
A pizza with a diameter of 13 inches is cut into 12 equal slices. Jayden eats 1/3 of the pizza, representing an area of ____ square inches. Carson eats 5 slices of pizza, representing an area of ____ square inches.
Answer:
Jayden consume pizza with an area of 44.2498 inches squared.
Carsen consumes pizza with an area of 55.3125 inches squared
Step-by-step explanation:
Diameter is 13 inches,
Radius is diameter divided by 2
Radius = 13/2 = 6.5 inches
Area = pi times radius squared
Area = 3.142 x 6.5^2 = 132.7495.
For jayden, 1/3 of this will be
1/3 x 132.7945 = 44.2498 inches squared.
For carsen, the 12 slice of pizza will each have an area of 132.7945/12 = 11.0625 inches squared,
5 of those slices will have area of 5 x 11.0625 = 55.3125 inches squared.
This sculpture designed by Mr. Newman’s colleague, Tia, is shaped like a hollow triangular pyramid. All 3 of the lateral faces are congruent and made of glass. How much glass was used to make the sculpture, if each face has a base length of 4 m and a slant height of 6 m? What is the area of each of the lateral faces? m² What is the total lateral area of the sculpture? m²
Answer: Each lateral face would have an area measuring 11.32 square metres.
(2) The total lateral area is 40.88 square metres.
Step-by-step explanation: A three-sided triangular prism as stated in the question would have triangular faces on all sides and since the one in the question is described as a hollow triangular pyramid, we can safely conclude that each surface is a flat/plane shape. Also, each of the triangular surfaces has a base length of 4 metres and a slant height of 6 metres. The surface area is given as
Area of a triangle = 1/2 * base * height
However, the height given is the slant height. Therefore to calculate the vertical height, we shall apply the Pythagoras' theorem, which means the triangular surface would have to be divided into two halves by a perpendicular line that splits the base length into two equal sides. This results in a right angled triangle with the hypotenuse measuring 6 metres and one of the two other sides measuring 2 metres. We now have
AC² = BC² + AB²
Where AC is the hypotenuse 6, BC is one of the other sides 2, and AB is the unknown (slant height).
6² = 2² + AB²
36 = 4 + AB²
Subtract 4 from both sides of the equation
32 = AB²
Add the square root sign to both sides of the equation
√32 = √AB²
5.66 = AB
The area of the triangular surface now becomes;
Area = 1/2*base*height
Area = 1/2 x (4 x 5.66)
Area = 1/2 x 22.64
Area = 11.32 metres²
The total of all three surfaces would be derived as
Surface areas = 11.32 x 3
Surface areas = 33.96 metres²
For the base area, with all three sides measuring 4 metres each, the area would be derived but first we need to calculate the slant height first.
With a line drawn perpendicular to one of the sides, we now have a right angled triangle with the hypotenuse as 4, one of the sides as 2, and the other side unknown (slant height).
AC² = AB² + BC²
4² = 2² + BC²
16 = 4 + BC²
Subtract 4 from both sides of the equation
12 = BC²
Add the square root sign to both sides of the equation
√12 = √BC²
3.46 = BC
The area of the base triangle now becomes;
Area = 1/2*base*height
Area = 1/2 x (4 x 3.46)
Area = 1/2 x (13.84)
Area = 6.92
The total lateral area would now become
Lateral area = Surface area + Base area
Lateral area = 33.96 + 6.92
Lateral area = 40.88 metres²
