Answer:
Step-by-step explanation:
It all depends on how many people are in your class.
To calculate probability
Determine a single event with a single outcome.
Identify the total number of outcomes that can occur.
Divide the number of events by the number of possible outcomes.
To determine the probability, Use the formula
What is the formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
P(A | B) = P(A∩B) / P(B)
A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound?
Answer:
1583362.7 termites
Step-by-step explanation:
A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound
The formula for the volume of a cone
= πr²h/3
Radius = r = 60cm
Height = h = 1.4 m
Converting to centimeters.=
1m = 100cm
1.4m = x
x = 1.4 × 100cm = 140 cm
Volume of the cone = π × 60² × 140/3
527787.5658 cm³
From the above question
1cm³ = 3 termites
527787.5658 cm³ = x
Cross Multiply
x = 3 × 527787.5658
x = 1583362.6974 termites
Approximately.= 1583362.7 termites
Answer:A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound

Search your home for a rectangular prism. Some examples are a cereal box, a CD case, or a coffee table. Measure your prism using appropriate units, such as inches, centimeters, or feet. (you can aslo make something up- as long as its an object that you can find in a house)
Complete ALL OF THESE. Show ALL work for calculations.
List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Describe the shape of the cross section when the box is cut parallel to the base.
What is the surface area of the box?
What is the surface area of the box if it is scaled up by a factor of 10?
What is the volume of the box?
What is the volume of the box if it is scaled down by a factor of 1/10
Answer:
I chose a box of cereal-------> rectangular prism
see the attached figure
Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length: 20 cm
Width: 8 cm
Height: 32 cm
Part 2).
Describe the shape of the cross-section when the box is cut parallel to the base
the shape of the cross-section would be a rectangle of dimensions
20 cm x 8 cm
Part 3)
What is the surface area of the box?
surface area=2*area of the base+perimeter of the base*height
area of the base=20*8=160 cm²
perimeter of the base=2*[20+8]-----> 56 cm
height=32 cm
surface area=2*160+56*32------> 2,112 cm²
the answer part 3) is
2,112 cm²
Part 4)
What is the surface area of the box if it is scaled up by a factor of 10?
we know that
surface area of the larger box=[scale factor]²*surface area original box
scale factor=10
surface area original box=2,112 cm²
so
surface area of the larger box=10²*2,112-----> 211,200 cm²
the answer part 4) is
211,200 cm²
Part 5)
What is the volume of the box?
volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³
the answer Part 5) is
5,120 cm³
Part 6)
What is the volume of the box if it is scaled down by a factor of 1/10
we know that
volume of the smaller box=[scale factor]³*volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³
the answer part 6) is
5.12 cm³

simplify the right hand side
-6x+6 that is not equal to -6x+1
Tell if the Ratio is Part-to-part or part-to-whole
4 apples to 3 oranges
Answer: Part-to-part
Step-by-step explanation:
This is a part-to-part, because they show part of apples, and part of oranges. This ratio when set up is 4:3. If the ratio was part-to-whole, then the apples would be compared to the total amount of oranges and apples. The ratio for part-to-whole would be 4:7.
Hope this helps!
Triangle ABC is similar to triangle WYZ.
Determine whether the following statement is true or false.
sin(B)>sin(Y)
true
false
The solution is, the following statement is, False.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
given that,
Triangle ABC is similar to triangle WYZ.
now, we get,
Corresponding angles in similar triangles are congruent.
The similarity statement tells you angle B corresponds to angle Y,
so those angles are congruent.
The sines of congruent angles are identical.
so, we have,
sin(B) > sin(Y) . . . . FALSE
sin(B) = sin(Y) . . . . true
Hence, The solution is, the following statement is, False.

What is the slope of the line?
Answer:
-3
Step-by-step explanation:
First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.
Answer:
-3
Step-by-step explanation:
slope = rise/run
rise = vertical distance
run = horizontal distance
Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.
For example, choose points (0, -3) and (-1, 0).
Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.
Step 3.
slope = rise/run
slope = 3/(-1) = -3
Answer: slope = -3

Three neighbors plan to complete fencing projects this spring. As shown in the diagrams below, Neighbor A plans to fence in his rectangular backyard with a 6-foot tall wooden privacy fence. Neighbor B plans to construct a circular chain link fence around his pool. And, Neighbor C is putting a vinyl fence around three side of his front yard. Note: Diagrams are not drawn to scale. Intended fences are marked with a dashed line.
Answer:
- The neighbor that has the most amount of fence to put up is: Neighbor A.
- The neighbor that has the least amount of fence to put up is: Neighbor C.
Step-by-step explanation:
To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:
Convert yards to feet (Remember that :
To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:
Where r is the radius.
In this case, the radius is:
Substituting, you get:
To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:
Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.
The neighbor that has the least amount of fence to put up is: Neighbor C.

a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?
Answer:
The answer is 20/30 or in simplified form 2/3
Step-by-step explanation:
The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.
