Hey there!
To solve this problem, we will take a look at the FOIL Method.
What is "FOIL"?FOIL is a simple acronym that can be used to multiply binomials. It stands for:
F - Front
O - Outer
I - Inner
L - Last
See the image below for an example of how to use this in the given situation.
ApplyFront: Multiply the two terms out in the front.
[tex](-5a)(-4a) = 20a^2[/tex]
Outer: Multiply the two terms on the outsides.
[tex](-5a)(3)=-15a[/tex]
Inner: Multiply the two terms on the insides.
[tex](6)(-4a)=-24a[/tex]
Last: Multiply the two terms in the back.
[tex](6)(3)=18[/tex]
AddNow, we add all of our answers from above:
[tex]20a^2-15a-24a+18[/tex]

Find missing angles of the following
Answer:
see below
Step-by-step explanation:
angle e is a vertical angle(each of the pairs of opposite angles made by two intersecting lines.) of 114 so e=114 and angle d is the vertical angle of 22 so d=22. and finally angles d+f+e=180
114+22+?=180
?=180-114-22
?=180-136
?=44
e=144
d=22

two friends Natasha and Trisha shared a sum of money in the ratio 5:3 respectively. if Trishia share is $ 120 calculate the total amount of money shared
The money shared by Natasha and Trisha is $160.
What is defined as the term ratio?A ratio is a measure of 2 or more numbers which indicates their relative sizes. A ratio compares two amount by dividing them, with the dividend or number divided referred to as the antecedent and thus the divisor or number divided referred to as the consequent.Let the amount paid by the Natasha is 'x'
And the amount Paid by Trisha is 'y';
Their amounts are in the ratio of 5:3
Thus, x/y = 5/3
Trisha shares a amount of $120.
y = $12.
Then, put y = 120 in the ratio.
x/y = 5/3
x = 5y/3
x = (5×12)/3
x = 5×4
x = 40 (amount shared by Natasha)
Total amount = Natash's share + Trisha's share
Total amount = 40 + 120
Total amount = 160
Thus, the total amount of money shared is $160.

Five Spanish friends are playing in a house. Cammy, Ann, Rake, Dora, Stephen. Cammy and Ann are playing Chess, while Rake and Dora are playing together. Then Stephen is playing by himself, which would mean he is playing One player games. Can you figure out which game they are playing?
Answer:
Step-by-step explanation:A. Solution:
So we know that Ann and Cammy are playing Chess, and Stephen is playing by himself, which would mean he is playing -ONE-player games. So we have Rake and Dora, when you see their names, it creates a word. Cammy, Ann, Rake, Dora, and Stephen.

(5, 1)
Find the slope of the line passing through the pair of points
m =
The slope of the line for the pair of points (4,5) and (5,1) is m= -4.
As given in the question,
Let the pair of points of the line are
(x₁ ,y₁) = (4, 5)
(x₂ , y₂) = (5,1)
Slope of the line passing through the pair of points (x₁ ,y₁) = (4, 5) and
(x₂ , y₂) = (5,1) is given by
m = (y₂ -y₁) / (x₂ - x₁)
⇒ m = (1-5) / (5 -4)
⇒ m = -4
Therefore, the slope of the line for the pair of points (4,5) and (5,1) is
m= -4.

An epidemiological study of the spread of a certain influenza strain that hit a small school population found that the total number of students, P, who contracted the flu t days after it broke out is given by the model P = -2²+ 17t + 180, where 1 st≤ 6. Find the day that 210 students had the flu. Recall that the restriction on this at most 6.
Submit Answer
Answer:
At the 3rd day 160 students caught flu.
Step-by-step explanation:
Consider the provided model P = − t ² + 13t + 130 where 1 ≤ t ≤ 6
The total number of students is represents by P.
We need to find the day that 160 students had the flu.
Substitute the value of P=160 in above formula.
Hence the value of t=10 or t=3
But it is given that 1 ≤ t ≤ 6, Therefore select t=3
Hence, at the 3rd day 160 students caught flu.

Find the 9th term of the arithmetic sequence 4x+44x+4, 9x+119x+11, 14x+18, 14x+18,...
Answer:
T9=60
Step-by-step explanation:
step 1: solve for x
it is an arithmetic pattern,so the 1st difference is the common difference (d)
therefore...9x+199x+11-(4x+44x+4)=14x+18-(9x+199x+11)
128x+11-48x-4=14x+18-128x-11
80x+7=-144x+7
80x+144x=7-7
224x=0
224x/224=0/224
X=0
step 2: substitute for x
4(0)+44(0)+4=4[1st term]
9(0)+119(0)+11=11(2nd term)
14(0)+18=18(3rd term)
step 3:find the common difference
d=3rd term- 2nd term, 2nd term-1st term
3rd term-2nd term
18-11=7
2nd term-1st term
11-4=7
therefore...d=7
step 4:find the general formula
we use the formula Tn=a+(n-1)d to find the general formula/ nth term
where: Tn is the nth term
a is the first term
n is the number of term
d is the common difference
Tn=a+(n-1)d
=4+(n-1)7
=4+7n-7
=7n-3
step 5:find the 9th term
Tn=a+(n-1)d
=7n-3
=7(9)-3

The answer of [tex](4)(4) -4(-5)(-1)[/tex] is [tex]-4[/tex]
We are supposed to find the answer of [tex](4)(4) -4(-5)(-1)[/tex].
This question is a classic example of the BODMAS rule in mathematics.
According to this rule, first we solve the sum inside bracket (be it any operation like division, multiplication, addition or subtraction) then division operation if present in the question followed by multiplication then addition and followed by subtraction.
Here in the question given [tex](4)(4) -4(-5)(-1)[/tex], we use BODMAS to solve it.
Let x be the answer of the above question, Therefore
[tex]x=(4)(4) -4(-5)(-1) \\x=(4*4)-4(5)\\x=(16)-(20)\\x=(16-20)\\x=-4[/tex]
Therefore[tex](4)(4) -4(-5)(-1)[/tex] = -[tex]4[/tex]
BODMAS: The BODMAS rule follows the order of the BODMAS abbreviated for B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – Subtraction. The BODMAS rule states that mathematical expressions with more than one operators need to be solved from left to right in the order of BODMAS.Want to learn more about BODMAS?

The probability that the interval estimation procedure will generate an interval that contains the actual value of the population parameter being estimated is the _____.
The population parameter being estimated is the confidence coefficient.
What is a confidence coefficient?The confidence coefficient is the confidence level stated as a proportion, rather than as a percentage. For example, if you had a confidence level of 99%, the confidence coefficient would be . 99. In general, the higher the coefficient, the more certain you are that your results are accurate.
probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Hence, The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the confidence coefficient.

The linear equation in terms of the variable R is determined as x = R/10.
Given data:
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
The given equation is:
R = x + 9x
First, let's combine the like terms on the right side of the equation:
R = 1x + 9x
R = 10x
Now, we want to solve for x. To isolate x, divide both sides of the equation by 10:
R/10 = x
So, the solution for x is:
x = R/10
Hence, the expression for in terms of R is x = R/10.
