Answer:
Rajiv bought 23,382 balls.
Step-by-step explanation:
Given that Rajiv bought 1325 packs of red balls, 1238 packs of yellow balls and 1334 packs of green balls, and there were 6 balls in each pack, to determine how many balls did Rajiv buy the following calculation must be performed:
(1,325 + 1,238 + 1,334) x 6 = X
3.897 x 6 = X
23.382 = X
Therefore, Rajiv bought 23,382 balls.
Simplify −5(2x−6)+25x . Write your answer in factored form.
Answer:
-5(2x-6)+25x
-10x+30+25x
25x-10x+30
15x+30
15(x+2)
Step-by-step explanation:
The factored form of the given expression is 15(x + 2).
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is as below,
−5(2x − 6) + 25x
It can be simplified as follows,
−5(2x − 6) + 25x
= -10x + 30 + 25x
= 15x + 30
= 15(x + 2)
Hence, the given expression can be simplified in factored form as 15(x + 2).

Find the probability of being below 514 if the mean of a normal distribution is 474 and the standard deviation is 32.
Question 13 options:
.8461
.8944
.1056
.1539
Second option is correct. That is the probability of being below 514 with the mean 474 and standard deviation 32 is 0.8944.
What is normal distribution?A function that represents the distribution of many random variables as a symmetrical bell shaped graph.
The normal distribution is a probability distribution, so the total area under the curve is always 1 or 100%.
What is z-score?A z-score is a numerical measurement that describes a value's relationship to mean of a group of values.
Formula for calculating z-scorez = (x -μ)/σ
where,
z is standard score
x is observed value
μ is mean of sample
σ is standard deviation of sample
According to the given question
we have
x = 514
μ = 474
and
σ =32
therefore,
Z- score will be
Z = (514 -474)/32 = 1.25
So, the area under the normal distribution curve z<1.25
⇒ P(x<1.25) = P(Z<1.25) = 0.894
Hence, second option is correct one. That is, the probability of being below 514 if the mean of a normal distribution is 474and the standard deviation is 32 is 0.894.

6 + (8 x 3) - 9 Enter the value
Answer:
Hello, so the answer is 21.
Step-by-step explanation:
Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.
So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.
Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.
Now, 24 minus 3 equals 21. So there we have it :)
Hope I helped!

Answer:
3.14 yd²
Step-by-step explanation:
Area = πr² = π(1)² = 3.14 yd²
Answer:
3.14
Step-by-step explanation:
because the area of a circle is pi × r^2, we can just plug in the value of r which is 1 yard
A = pi × (1)^2
A = pi × 1
A = pi or 3.14
what is the domain of the relation enter each value on the same line separated by commas. consider the relation { (9,1), (4,5), (6,2), (8,6), (1,2)}
Answer:
D = {1, 4, 6, 8, 9}
Step-by-step explanation:
A relationship maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, set of the outputs).
Such that the usual notation is: (x, y)
this says that the relationship maps the element x into the element y.
In this case, we have the relation:
" { (9,1), (4,5), (6,2), (8,6), (1,2)}"
The inputs are the first value for each pair, then the set of the inputs (also called the domain) is:
D = {9, 4, 6, 8, 1}
And we can rewrite this in order to get:
D = {1, 4, 6, 8, 9}

c is the unknown hypotenuse
Use the pythagorean theorem to find c
a^2 + b^2 = c^2
9^2 + 40^2 = c^2
81 + 1600 = c^2
c^2 = 1681
c = sqrt(1681)
c = 41 meters is the length of the hypotenuse

give the right answer and the explanation plss
Answer:
5.143m
Step-by-step explanation:
Since we are not asked what to find, we can find the height of the building
Given
Length of ladder (hypotenuse) = 6m
angle of elevation = 59°
Required
Height of building H (opposite)
Using the SOH CAH TOA identity
sin theta = opp/hyp
sin 59 = H/6
H = 6sin59
H = 6(0.85716)
H =5.143
Hence the height of the building is 5.143m

Heather's family has 2 adults and 3 kids. The tickets to the musical cost them $72.85.
Carl's family, on the other hand, paid $94.75 for 2 adults and 5 kids. How much higher
was the cost of an adult's ticket compared to a kid's ticket? Let the cost of an adult's
ticket be x and the cost of a kid's ticket be y.
Answer:
$9.05
Step-by-step explanation:
x = $adult
y = $kid
2x + 3y = 72.85 (Heather)
2x + 5y = 94.75 (Carl)
subtract the equations to get:
-2y = -21.90
y = 10.95
solve for 'x':
2x + 3(10.95) = 72.85
2x + 32.85 = 72.85
2x = 40
x = 20
Difference between 20 and 10.95 is $9.05

Compare the triangles and determine whether they be proven congruent, if possible, by SSS, SAS, ASA, AAS, or HL. Write your answer in the box.
========================================================
Explanation:
The sides shown by the single tickmark are the same length. That's one "S" of "SSS".
The sides shown with double tickmarks are the same length. This is another "S" of "SSS".
Lastly, the third unmarked sides of each triangle overlap together perfectly. We consider this a shared side. They are the same length due to the reflexive property. This is the third "S" of "SSS".
The order of the "S" terms mentioned above doesn't matter. All that matters is that we have three pairs of congruent sides. This is enough to use the SSS congruence theorem to prove the two triangles are congruent.
--------------
Extra info:
We don't have any information about the angles, so we cannot use ASA, SAS, or AAS.
We can't use HL because that only applies to right triangles.

2x+15=33 solve for x
Answer:
x = 9
Step-by-step explanation:
2x + 15 = 33
2x = 33 - 15
2x = 18
x = 18/2 = 9
Answer:
x=9
Step-by-step explanation:
2x+15=33
Subtract 15 from each side
2x+15-15=33-15
2x=18
Divide by 2
2x/2 = 18/2
x = 9
Solve for x solve for x solve for x
Answer:
10.2
Step-by-step explanation:
The sum of the three angles is 180, since they form a straight line
8x-15 + 58+ 3x+25 = 180
Combine like terms
11x +68 = 180
Subtract 68 from each side
11x+68-68= 180-68
11x =112
Divide by 11
11x/11 = 112/11
x = 10.181818181
x = 10.2
Given info:-In the given figure, points A,B and C are collinear or they are straight line. Where angle ABC , angle DBE and EBC are in formed of linear pair that mean they are 180. And here we are going to find out the value of X?
angle ABD+ angle DBE + angle EBC = 180° {Angles of a linear pair]
⇛(8x-15)°+(58)°+(3x+25)° = 180°
Remove all the brackets in LHS.
⇛8x° - 15° + 58° + 3x° + 25° = 180°
⇛11x° - 15° + 58° + 25° = 180°
⇛11x° - 15° +83° = 180°
⇛11x° + 68° = 180°
⇛11x° = 180° - 68°
⇛11x° = 112
Shift the number 11° from LHS to RHS.
⇛x = 112÷11 ⇛112/11 =
The value of x = 10.181818.. = 10.18 bar
