Answer:
Number of adult tickets sold = 1170
Number of children tickets sold = 85
Step-by-step explanation:
Let,
x be the number of adult tickets sold
y be the number of child tickets sold
According to given statement;
x+y = 1255 Eqn 1
10x+7y=12295 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=1255)
10x+10y=12550 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(10x+7y) = 12550 - 12295
10x+10y-10x-7y= 255
3y = 255
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{255}{3}\\y=85[/tex]
Putting y=85 in Eqn 1
x+85 = 1255
x = 1255-85
x = 1170
Hence,
Number of adult tickets sold = 1170
Number of children tickets sold = 85
A company that makes hair-care products had 6,000 people try a new shampoo. Of the 6,000 people,
36 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
% of the people had a mild allergic reaction,
Answer:
0.6% of the people had a mild allergic reaction.
Step-by-step explanation:
Given that:
Number of people who tried hair care products = 6000
Number of people who had reaction = 36
Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{36}{6000}*100[/tex]
Percent of people = 0.6%
Hence,
0.6% of the people had a mild allergic reaction.

Plz help I don’t understand how to find x?
Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.

Express (x + 10)^2 as a trinomial in standard form.
Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
The required trinomial in standard form is x²+20x+100.
Trinomial:Important information:
The expression is the [tex](x+10)^2[/tex].Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]
[tex](x+10)^2=x^2+20x+100[/tex]
Therefore, the required trinomial in standard form is x²+20x+100.

The graph of a line on a coordinate plane has a slope of 1/2 and passes through the point (4, -3). Which equation describes the line?
Answer:
[tex]\boxed {\boxed {\sf y= \frac{1}{2}x-5 }}[/tex]
Step-by-step explanation:
Since we are given a point and a slope, we should use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point the line passes through.
We are given the slope of 1/2 and the point (4, -3). Therefore:
[tex]m= \frac{1}{2} \\x_1= 4\\y_1= -3[/tex]
Substitute the values into the formula.
[tex]y--3= \frac{1}{2} (x-4)[/tex]
[tex]y+ 3= \frac{1}{2} (x-4)[/tex]
Distribute the 1/2. Multiply each term inside the parentheses by 1/2.
[tex]y+3= \frac{1}{2} *x + \frac{1}{2} * -4[/tex]
[tex]y+3=\frac{1}{2}x-2[/tex]
We want to the equation of the line in slope-intercept form or y=mx+b. We need to isolate y. 3 is being added and the inverse of addition is subtraction. Subtract 3 from both sides of the equation.
[tex]y+3-3=\frac{1}{2}x-2-3[/tex]
[tex]y=\frac{1}{2}x-2-3\\y= \frac{1}{2}x-5[/tex]
The equation of the line is y=1/2x-5

Interest can be the money paid by a bank to a consumer as compensation for keeping their money in that bank. Interest can also be the money paid to a bank for the use of their money.
Answer: See explanation
Step-by-step explanation:
You didn't really say what you want but the above statement is true.
Interest can be the money paid by a bank to a consumer as compensation for keeping their money in that bank. This is because when an individual or a company keeps some amount of money with a bank, an interest is paid on that money and the longer the time duration, the higher the interest paid.
Also, Interest can also be the money paid to a bank for the use of their money. When someone goes to the bank to collect a loan, the bank charges an interest on that amount borrowed. For example, if one borrows $10,000, an interest of let's say 8% may be charged for a 2 years loan. Therefore, the interest would be:
= $10000 × 8% × 2
= $1600.

Answer:
1. Trinomial 2. Trinomial 3. Monomial 4. Binomial 5. Binomial
Step-by-step explanation:
The numbers with variables attached are called terms, and how many there are defines the equation. It doesn't matter how many variables or exponents are attached, there could be none or 15 each to the power of 6 but it's still one term. "Mono" means one, so there's only one term, "Bi" means two, so there are two terms, and "Tri" means three, so there are three terms. "Poly" applies to everything above three, though unused words for the bigger terms do exist.

How many solutions does this system of equations have? y=3x+1 y=3x+7
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
This equation has no solution.
What is the inconsistent system?An inconsistent system is a system that has no solution in any case scenario.

Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
Perimeter
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
Area
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.
