Please help me with this question!!!!
Answer:
EH = 13 in
Step-by-step explanation:
Angle between a tangent and radius is right, that is
∠ EBH = 90° and so Δ EBH is right
Using Pythagoras' identity in the right triangle
EH² = BE² + BH² = 5² + 12² = 25 + 144 = 169 ( square root both sides )
EH = [tex]\sqrt{169}[/tex] = 13

#BrainlyIsFunLast year, 120 new houses were built in a neighborhood. So far this year, 2/3
of them have been sold. How many new houses have been sold this year?
Write your answer in simplest form.
Multiply the total number of houses built by the fraction sold:
120 x 2/3 = (120 x 2)/3 = 240/3 = 80
80 houses were sold.
A school sells 712 tickets for a talent show. Adult tickets cost $8 each, and children's tickets cost $4 each. A total of $4,256 is collected
from ticket sales. Which system of equations can be used to determine the number of adult tickets sold, x, and the number of children's
tickets sold, y?
O A. x + y = 712
4x + 8y = 4,256
OB. x + y = 712
8x + 4y = 4,256
C. X + 8y = 712
x + 4y = 4,256
OD. 8x + y = 712
4x + y = 4,256
Answer:
B
x + y = 712
8x + 4y = 4,256
Step-by-step explanation:
If x=the amount of adult tickets, and y=the amount of children's tickets, then the total amount of tickets (712) should be x+y. Our first equation: x+y=712
The total made from adult tickets is found by multiplying the amount of tickets by the price per ticket: 8x. The total made from children's tickets is found by multiplying the amount of tickets by the price per ticket: 4y.The total amount of money made (4256) is the sum of the amount made by adult tickets (8x) and the amount made by children's tickets (4y). Our second equation: 8x+4y=4256

Heather is a software saleswoman. her base salary is 1900, and she makes an additional $40 for every copy of math is fun she sells.
let P represent her total pay (in dollars) and N represent the number of copies of math is fun she sells. write and equation relating P to N and use this equation to find her total pay if she sells 27 copies of math is fun.
Answer:
[tex]P = 1900 + 40N[/tex]
[tex]P = 2980[/tex] when N = 27
Step-by-step explanation:
Given
[tex]Base\ Salary = 1900[/tex]
[tex]Additional = 40[/tex] per copy
Solving (a): Her total pay (P)
This is represented by:
[tex]P = Base\ Salary + Additional * N[/tex]
[tex]P = 1900 + 40 * N[/tex]
[tex]P = 1900 + 40N[/tex]
Solving (b): Total pay when N = 27
Substitute 27 for N
[tex]P = 1900 + 40 * 27[/tex]
[tex]P = 1900 + 1080[/tex]
[tex]P = 2980[/tex]
Can some please answer this
9514 1404 393
Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B

find the value of x and y in the following figure where ABCD is a parallelogram
Answer:
x = 3
y = 2
Step-by-step explanation:
Diagonals of a parallelogram bisect each other into two equal segments. Therefore:
3x - 1 = 2(x + 1)
Solve for x
3x - 1 = 2x + 2
Collect like terms
3x - 2x = 1 + 2
x = 3
Also:
5y + 1 = 6y - 1
Collect like terms
5y - 6y = -1 - 1
-y = -2
Divide both sides by -1
y = -2/-1
y = 2

Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y = mx + b
"m" is slope
"b" is y-intercept (coordinates are (0, b)
Parallel lines have the same slopes and different y-intercepts.
Slopes of perpendicular lines are opposite reciprocals: [tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
~~~~~~~~~~~~~~~~~~~~~~
[tex]L_{1}[/tex] : y = x + 5 , [tex]m_{L_{1} }[/tex] = 1 , b = 5
[tex]L_{2}[/tex] : y = - x + 7 , [tex]m_{L_{2} }[/tex] = - 1 , b = 7
[tex]L_{1}[/tex] ⊥ [tex]L_{2}[/tex]
[tex]L_{3}[/tex] : [tex]m_{L_{3} }[/tex] = 1 , b = - 2

A process that fills packages is stopped whenever a package is detected whose weight falls outside the specification. Assume that each package has probability 0.02 of falling outside the specification and that the weights of the packages are independent. Find the mean number of packages that will be filled before the process is stopped. Numeric Response
Answer:
The mean number of packages that will be filled before the process is stopped is 50.
Step-by-step explanation:
For each package, there are only two possible outcomes. Either it fails outside the specifications, or it does not. Packages are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Number of trials expected for n sucesses
Also called inverse binomial distribution, is given by:
[tex]E = \frac{n}{p}[/tex]
In which p is the probability of a success in a trial.
Assume that each package has probability 0.02 of falling outside the specification and that the weights of the packages are independent.
This means that [tex]p = 0.02[/tex]
Find the mean number of packages that will be filled before the process is stopped.
This is when [tex]n = 1[/tex], as the process is stopped when a package is outside the specifications. So
[tex]E = \frac{n}{p} = \frac{1}{0.02} = 50[/tex]
The mean number of packages that will be filled before the process is stopped is 50.

What are all of the zeros in this equation?
Answer:
0, 1 and 1
Step-by-step explanation:
Given the expressions;
x^3-2x^2+x = 0
x(x^2-2x+1) = 0
x = 0 and x^2-2x+1 = 0
Factorize x^2-2x+1 = 0
x^2-x-x+1 = 0
x(x-1)-1(x-1) = 0
(x-1)(x-1)= 0
x = 1 twice
hence the zeros of the equation are 0, 1 and 1

Answer:
I. Ella packed 70 books more than Ray.
II. Ray packed 580 books.
III. Ella packed 650 books.
Step-by-step explanation:
Given the following data;
Ray = 29 boxes of 20 books
Ella = 26 boxes with 25 books
To find the total number of books packed by Ray;
Total for Ray (Ray packed) = 29 * 20
Total for Ray = 580 books.
To find the total number of books packed by Ella;
Total for Ella (Ella packed) = 26 * 25
Total for Ella = 650 books.
Next, we find the difference between the books packed by Ella and Ray;
Difference = Ella - Ray
Difference = 650 - 580
Difference = 70 books
