Answer:
5/18
Step-by-step explanation:
Here,
total numbering balls n(S) = 18
total number of winning balls n(B) = 5
Therefore,
Probability or winning chances P(B)=
n(B)/n(S)
= 5/18
Dwayne is making a documentary about the formation of rocks. He started on Wednesday with
a certain amount of film footage and then added 3.75 hours. Then, on Friday he cut 0.28 hours
of footage. Over the weekend he cut another 1.3 hours of footage. On Monday he added 1.25
more hours of footage and finally on Tuesday got rid of another 2.7 hours of footage to have his
final film length. If Dwayne started on Wednesday with 6.8 hours of footage, what was the final
length of his documentary? Round your answer to the nearest tenth if necessary.
The lengths of the sides of triangle ABC are represented in terms of the variable m, where m > 6.
AB = m – 2
BC = m + 4
AC = m
List the angles from smallest to largest.

✔ A
.
Answer:
m(C)<m(B)<m(A).
Step-by-step explanation:
1) according to the condition the shortest side is AB, the longest side is BC, the middle is AC. Then
2) the smallest angle is BCA (or C), the middle angle is ABC (or B), the largest angle is BAC (or A).
The list of the angles from smallest to largest are C, B and A.
Given that a triangle has side measurements represented in terms of the variable m, where m > 6.
AB = m - 2
BC = m + 4
AC = m
We need to list the angles from smallest to largest.
Since none of the sides are equal, therefore it is a scalene triangle.
Let us consider m = 6.
Then,
AB = m - 2
AB = 6 - 2
AB = 4
BC = m + 4
BC = 6+4
BC = 10
AC = m
AC = 6
It means that the longest side is BC, the medium side is AC and the shortest side is AB.
We know that the longest side of a triangle corresponds to the largest angle and vise versa.
Therefore,
The smallest angle is angle C.
The medium angle is angle B.
The largest angle is angle A

Which of these strategies would eliminate a variable in the system of equation?
2x+3y=-5
2x-3y=10
One of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"
Eliminating variables from the system of equations?System of equations consists of a different set of equations with unknown variables.
Given the system of equations
2x+3y=-5
2x-3y=10
Since the coefficient of x from both equations are the same, we will subtract both equations to eliminate the variable "x"
(2x-2x)+(3y+3y) = -5 + 10
6y = 5
Hence we can conclude that one of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"

Answer:
There are 20 caramel apples that are covered with sprinkles.
Step-by-step explanation:
First we should make all of these have a common denominator. We could make these be 1/5 = 6/30, 1/3 = 10/30, 3/10 = 9/30. Now we can add them all up. 6 + 10 + 9 = 25/30. Now, to figure out how many apples is 1/30. 120 divided by 30 = 4. Now we can do 4x25 because that's how many non sprinkle apples there are. This is 100. 120 - 100 = 20. You could have also done 4x5 because there were 5/30 sprinkle apples, and gotten the same answer.
so, there are 20 caramel apples that are covered with sprinkles.

- You work in the human resources department of a
company. Per the employee benefits package, each
employee earns 1 and 1/2 vacation days per month. You
need to calculate the total number of vacation days
that an employee earns in a year. How many total
vacation days will an employee earn in a year?
Answer:
18 Days Off
Step-by-step explanation:
Firstly, to solve this question you have to identify how many months are in a year; that's 12. So now we know:
Each employee can take 1 1/2 days off in a monthThere are 12 months in a yearMaking a formula for calculation is the best way to do this, especially since we now have all of the information needed to answer.
VacationDays=1 [tex]\frac{1}{2}[/tex] × 12
Vacation days are the total number of vacation days in a year.
∴VD= 1 [tex]\frac{1}{2}[/tex] x 12
VD= 18
∴Total vacation days equal 18
Each employee gets 18 vacation days in a year.

Find the approximate length of C
Answer:
c = 2√3 ≈ 3.464
Step-by-step explanation:
A 30°-60°-90° triangle is a "special" triangle that has sides in the ratios ...
1 : √3 : 2 . . . . . shortest to longest.
Comparing those to the side measures you have, we see ...
1 : √3 : 2 = b : 3 : c
Multiplying the basic ratios by √3 gives a value that matches the long side:
√3 : 3 : 2√3 = b : 3 : c
Then the value of c is 2√3 ≈ 3.464.

Additional comment
Side length b is √3 ≈ 1.732.

What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that the two terms are 6√3 and 3√6.
We have to find the product of the given terms,
Radical notation is the term for an expression that employs a root, such as the square or cube root.
=6√3 × 3√6
=( 6 × 3 )√( 6 × 3 )
=18√18
= 18√(2×9)
=18 ( √2 × √9 )

Please help! Brainlist and points
Answer:
x = sqroot(122)
Step-by-step explanation:
First find the line that goes thru the middle of the shape. It is the hypotenuse of the bottom/left triangle. Use the pythagorean thm.
9^2 + 5^2 = h^2
81 + 25 = h^2
sqroot106 = h
Now sqroot106 is a leg in the right triangle that is on the top/right in the image.
Use pythagorean thm again.
4^2 + (sqroot106)^2
= x^2
16 + 106 = x^2
122 = x^2
sqroot122 = x

Explanation:
The figure is an unfolded version of a pyramid, so it's placed as flat as possible.
The square in the middle has area of 7*7 = 49 square meters. This is the base or floor of the pyramid.
Each triangle has area of base*height/2 = 7*5/2 = 35/2 = 17.5 square meters. Four such identical triangles combine to an area of 4*17.5 = 70 square meters. This is the lateral surface area, which is everything but the base.
So the total surface area is
BaseArea + LateralSurfaceArea = 49+70 = 119 square meters
