In the triangle ABC
are drawn two sides
of it, BB1 and AA1.
Those half-edges
intersect at point O.
What is the length of
the semicircular BB1
if B10 = a cm?
Answer:
3a
Step-by-step explanation:
What we have as the point O refers to the centroid of the triangle
The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter
So what we have here is that;
B1O is half the length of BO
So, if B1O is a cm, BO would be 2a
So we have the entire side length measure as;
a + 2a = 3a
The volume of a cone-shaped hole is 25 pi ft cubed . If the hole is 3 ft deep, what is the radius of the hole?
Answer:
5ft
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Volume = 25π ft cubed
Depth = 3 ft
So, we can calculate the radius by using following formula,
V = 1/3 ×π ×radius squared×depth
25π = 1/3×π×radius squared ×3
Radius squared = 25
Radius = √25
Radius = 5 ft
Hence the radius of the hole is 5 ft.
Find the missing side.

The probabilty that a student owns a car is 0.65 the porbability that a student owns a compuer is 0.82 the probability that a student owns both is 0.55what is the probability that a student owns both and what is the probability that a student owns none
Question: The probability that s student owns a car is 0.65, and the probability that a student owns a computer is 0.82.
a. If the probability that a student owns both is 0.55, what is the probability that a randomly selected student owns a car or computer?
b. What is the probability that a randomly selected student does not own a car or computer?
Answer:
(a) 0.92
(b) 0.08
Step-by-step explanation:
(a)
Applying
Pr(A or B) = Pr(A) + Pr(B) – Pr(A and B)................. Equation 1
Where A represent Car, B represent Computer.
From the question,
Pr(A) = 0.65, Pr(B) = 0.82, Pr(A and B) = 0.55
Substitute these values into equation 1
Pr(A or B) = 0.65+0.82-0.55
Pr(A or B) = 1.47-0.55
Pr(A or B) = 0.92.
Hence the probability that a student selected randomly owns a house or a car is 0.92
(b)
Applying
Pr(A or B) = 1 – Pr(not-A and not-B)
Pr(not-A and not-B) = 1-Pr(A or B) ..................... Equation 2
Given: Pr(A or B) = 0.92
Substitute these value into equation 2
Pr(not-A and not-B) = 1-0.92
Pr(not-A and not-B) = 0.08
Hence the probability that a student selected randomly does not own a car or a computer is 0.08

The number of freshman who prefer cats, hamsters, and fish is more than those who prefer dogs.
O Dogs were the preferred pet.
O One-fourth of the freshman surveyed prefer hamsters.
The number of freshman who prefer fish and hamsters is the same as those who prefer dogs.
The most preferred pets by students are Dogs. Therefore, the correct answers are B and C option.
A. It is given that, the number of Dogs are 28.
B. It is given that, the number of other Pets are
7+15+10 = 32
Thus, the number of other pets are greater than dogs.
C. The total number of pets are 60.
Here, the number of hamsters are
1/4 ×60 = 15
D. The number of hamsters and fish
= 15+10 = 25
The number of dogs are more than the number of fish and hamsters
Therefore, the correct answers are B and C option.

Step-by-step explanation:
The simplified expression of 4/11 is 4/11
How to simplify the expressionFrom the question, we have the following parameters that can be used in our computation:
4/11
This means that we divide 4 by 11
So, we have the following representation
4/11

The mean of six numbers is 184.2. The mean of five of the numbers is 178. What is the sixth number?
Answer:
I'm sorry I'm not very good at math, sorry I couldn't help
Answer: 215.2
Step-by-step explanation:
Since the mean of six numbers is 184.2, this means that their total sum will be:
= 184.2 × 6
= 1105.2
Since the mean of five of the numbers is 178, their total sum will be:
= 178 × 5
= 890
Therefore, the sixth number will be:
= 1105.2 - 890
= 215.2
The sixth number is 215.2

Need help! I’m rlly struggling with this math. Can anyone explain how to do it?
=======================================================
Explanation:
As you can probably guess, the first equation [tex]a_1 = 3[/tex] says that the first term is 3. The small '1' indicates "first term". So writing [tex]a_2[/tex] represents the second term, then [tex]a_3[/tex] is notation for the third term, and so on.
The second term is found by plugging in n = 2 into the second equation and computing to get...
[tex]a_n = 4*a_{n-1} + 2\\\\a_2 = 4*a_{2-1} + 2\\\\a_2 = 4*a_{1} + 2\\\\a_2 = 4*3 + 2\\\\a_2 = 12 + 2\\\\a_2 = 14\\\\[/tex]
The second term is 14. The steps above basically say: "to get the second term, we multiply the first term by 4, then add on 2"
In other words,
second term = 4*(first term) + 2
second term = 4*(3) + 2
second term = 12 + 2
second term = 14
-----
This can be extended to get the third term
third term = 4*(second term) + 2
third term = 4*(14) + 2
third term = 56 + 2
third term = 58
and finally,
fourth term = 4*(third term) + 2
fourth term = 4*(58) + 2
fourth term = 232 + 2
fourth term = 234

find the area of the shaded region. Use 3.14 for pi
Answer:
This shaded region is consisted of 2 shapes: a right triangle and a semi-circle. To find the overall area, we must first find the are of the 2 shapes and add them together.
Step-by-step explanation:
1. Find the area of the right triangle:
a = 14, b = 2r = 8cm
A1 = ab/2 = 112/2 = 56cm²
2. Find the area of the circle:
r = 4 cm
A2 = πr² = 3.14 × 4² = 50.24cm²
3. Divide the area of the circle to get the area of the semi-circle:
A3 = A2/2 = 50.24/2 = 25.12cm²
4. Add the areas of the right triangle and the semi-circle together:
A1 + A3 = 56 + 25.12 = 81.12cm²

The total fees for the high school play are
$250. Tickets to the play cost S5 for
students and S8 for nonstudents. Write a
linear inequality that describes the number
of student and nonstudent tickets that nccd
to be sold for the drama class to be able to
pay the fees.
Answer:
250[tex]\leq[/tex]5s+8ns
Step-by-step explanation:
the total fees are $250, meaning they would still be able to make the fees if they'd oversell the tickets.
each tickets is $5 for students; hence the s
each tickets is $8 for nonstudents; hence the ns
you may replace the variable with anything you'd like or what fits the direction.
The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, The total fees for the high school play are $250. Tickets to the play cost $5 for students and $8 for non students.
Let the cost of students be x and that of non student's be y.
According to question,
5x+8y≥ 250
Hence, The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250

(30 POINTS) Which function is represented by this graph?
A.
f(x) = -|x − 1| + 8
B.
f(x) = -|x − 8| + 1
C.
f(x) = -|x + 8| − 1
D.
f(x) = -|x + 1| − 8
Answer:
A.
Step-by-step explanation:
x-1 moves the graph to the right 1 and + 8 moves it up 8
this puts the vertex at (1,8) and the negative infront of the x makes the graph point down like it is.
The function represented by the graph is : f(x)=-|x-1|+8
The correct option is (A).
What is graph?A graph is a mathematical diagram which shows the relationship between two or more sets of numbers or measurements.
If we look at the graph, only the portion x-1 makes to move the graph to the right 1 and moves it up 8 which makes the coordinate (1,8).
Also, the negative at the front of x makes graph to move downwards.
Hence, the graph represented the function : f(x)=-|x-1|+8
