Answer:
18.17 × pi in²
Step-by-step explanation:
there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).
do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?
well, here we know the diameter (this means it is 2 times the radius) and the slant height.
this is one of the easiest exercises.
the formula for this case is
LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =
= pi × 2.3 × 7.9 = 18.17 × pi in²

Rajani has a bag that contains strawberry chews, cherry chews, and lime chews. She performs an experiment. Rajani randomly removes a chew from the bag, records the result, and returns the chew to the bag. Rajani performs the experiment 38 times. The results are shown below: A strawberry chew was selected 23 times. A cherry chew was selected 4 times. A lime chew was selected 11 times. Based on these results, express the probability that the next chew Rajani removes from the bag will be strawberry or cherry as a fraction in simplest form.

A trapezoid has sides of length 11 inches, 1.5 inches, 11 inches, and 19.1 inches. What is the perimeter?
Answer:
The Perimeter of the trapezoid = 42.6 inches
Step-by-step explanation:
______
Formula:
let a , b , c , d be consecutively the lengths of the sides of the trapezoid
then
The Perimeter of the trapezoid = a + b + c + d
___________________________________
Suppose a = 11 , b = 1.5 , c = 11 , d = 19.1
therefore,
The Perimeter of the trapezoid = a + b + c + d
= 11 + 1.5 + 11 + 19.1
= 42.6

Suppose that Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. Let A be the event that the
sum of the dice is 8 and B be the event that Eitan rolls doubles. Using the sample space of possible outcomes
below, answer each of the following questions,
What is P(A), the probability that the sum of the dice is 8?
What is P(B), the probability that Eitan rolls doubles?
What is P(A and B), the probability that the sum of the dice is 8 and Eitan rolls doubles?
Are events A and B independent?
Choose 1 answer:
A Yes, events A and B are independent events.
No, events A and B are not independent events.
Given : Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. A be the event that the sum of the dice is 8 and B be the event that Eitan rolls doubles
To find : probability of event A , event B , Event A or B , Event A & B
Solution:
Six Sides Dice has { 1 , 2 , 3 , 4 , 5 ,6 }
4 Sides Dice has = { 1 , 2 , 3 , 4 }
Total possible outcome = 6 * 4 = 24
n(S) = 24
A = Sum of Dice = 8
(4 , 4) , ( 5 , 3) , ( 6 , 2)
n(A) = 3
B = Double ( means same number on each Dice )
B = ( 1 , 1) , ( 2, 2) , ( 3 , 3) , ( 4, 4)
n(B) = 4
A U B = ( 1 , 1) , ( 2, 2) , ( 3 , 3) , ( 4, 4) ( 5 , 3) , ( 6 , 2)
n (A U B ) = { 6 }
A ∩ B = { 4 , 4}
n(A ∩ B) = 1
Probability of Event A = 3/24 = 1/8
probability of Event B = 4/24 = 1/6
Probability of Event A or B = 6/24 = 1/4
Probability of Event A and B = 1/24

In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them play baseball. There are 5 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?
The probability that a student is chosen randomly from the class plays both basketball and baseball is 4/21
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcomeIf the total number of people in the class is 21 students, hence the total outcome is 21Get the number of students that plays both basketball and baseball
n(U) = n(B)only + n(Ba)only + n(BnBa) + n(BuBa)'
21 = 6-x + 14-x + x + 5
21 = 25 -x
x = 25 - 21
x = 4
Hence 4 students play both basketball and baseball
Pr(basketball and baseball) = 4/21
Hence the probability that a student chosen randomly from the class plays both basketball and baseball is 4/21

NO LINKS!! Use the cylinder shown to mark each statement as true or false. Rewrite and correct any false statements.
Problem 9
Answer: FalseReason:
The height of the cylinder is 2.5 ft. It's misleading because the cylinder is tipped onto its side, so it appears that 4 ft is the height. The height of any cylinder is always perpendicular to the circular base. It might help to rotate the paper so that the circular base is horizontal.
==============================================================
Problem 10
Answer: FalseReason:
The diameter of the base is 4 feet, which divides in half to 2 feet and it's the radius of the circle.
Area = pi*(radius)^2 = pi(2)^2 = 4pi
So the area expression should be either pi(2^2) or pi(4) or 4pi
==============================================================
Problem 11
Answer: TrueReason:
V = pi*r^2*h
V = 3.14*2^2*2.5
V = 31.4 cubic feet
This volume is approximate since pi = 3.14 is approximate.
Find the area of the figure
Answer:
132cm^2
Step-by-step explanation:
to solve for the area of this we can split it into smaller shapes and sum the areas afterward-
the top rectangle has an area equal to Length x Width
4x7 = 28cm^2
the centre rectangle is done similarly-
7x8 = 56cm^2
lastly the two triangles which are solved with base x height divided by two
now since we know that the centre piece is 7cm across, and that the two side triangles are equal in size, that means that we know the base to be 19-7 divided by 2 which gives 6 each-
[tex]\frac{(6)(8)}{2}[/tex] (2) = (6)(8) = 48cm
now summing them we have 28 + 56 + 48 = 132cm^2

Answer:
B (x= 14/3 , y= -5/3)
Step-by-step explanation:
A (x= 6, y= 1) and C (x= 2, y = -7)
On x-axis between A and C are 6 -2 = 4 units
On y-axis between A and C are 1 + 7 = 8 units
AB = (1/3) BC
Divide the distance between AC in 3 pieces
On x-axis will have 4/3 units on each piece
On y-axis will have 8/3 units on each piece
Now move away from A the 1/3 distance
A (x= 6, y= 1)
B (x= 6 -(4/3) , y= 1 -(8/3))
B (x= (18- 4)/3) , y= (3-8)/3))
B (x= 14/3 , y= -5/3)
To feed his plants logan creates a mixture that requires 3/8 cup of plant food for every gallon of water. If he uses 10 1/2 gallons of. Water what is the total amount of. Plant food he needa
Answer:
[tex]3\ \frac{15}{16}[/tex]
Step-by-step explanation:
The mixture requires 3/8 cup of plant food for every gallon of water
Then it requires (10 1/2)×(3/8) cup of plant food for 10 1/2 gallons of water
Now we have to calculate (10 1/2)×(3/8)
[tex]10\ \frac{1}{2} \ =\ \frac{10\times 2}{2} +\frac{1}{2} \ =\frac{20+1}{2} =\frac{21}{2}[/tex]
[tex]\frac{21}{2} \times \frac{3}{8} =\frac{63}{16} =3\ \frac{15}{16}[/tex]

Find the perimeter and area of the shaded region.
Answer:
1. 144 m; 2. 720m²;
Step-by-step explanation:
1.
First we need to know how much edges are of the figure. Since there is 12, we need to multiple the length of an edge to how many of them are:
12 • 12 = 144 m
2.
Since one edge is 12 m, first calculate the plot of a little square (as there are 5 in the pic):
12 • 12 = 144 m² (one square)
Now we know that one square's plot is 144 m².
Since there is 5 of them, we need to multiply the plot 5 times, since there are five mini squares:
144 • 5 = 720 m²
Now we know the plot of the full figure.
