A pet store has 4 tanks of fish. Each tank has k fish. Using k, write an expression for the total number of fish in the store
Answer:
An expression for the total number of fish in the store would be 29n .
You can use this expression to find the number of fish in the store for any number of tanks, For example , if there are 5 tanks (or n is 5), the total number of fish would be 29 * 4 = 116fish.

solve the quadratic equations
x^2 -8x + 35 = 0
x^2 +8x + 25 = 0
Answer:
x^2=8x-35
Step-by-step explanation:
1.1 Factoring x2-8x+35
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is +35
Step-1 : Multiply the coefficient of the first term by the constant 1 • 35 = 35
Step-2 : Find two factors of 35 whose sum equals the coefficient of the middle term, which is -8 .
-35 + -1 = -36
-7 + -5 = -12
-5 + -7 = -12
-1 + -35 = -36
1 + 35 = 36
5 + 7 = 12
7 + 5 = 12
35 + 1 = 36
At the city museum, child admission is $6.00 and adult admission is $9.60. On Tuesday, 177 tickets were sold for a total sales of $1350.00. How many adult
tickets were sold that day?
80 adult tickets were sold that day.
This is a two equation problem.
First, let:
a = adult tickets
c = child tickets
[tex]6c + 9.6a = 1350[/tex]
[tex]c + a = 177[/tex]
Now, solve for either variable (c or a). We're going to isolate "c" in the second equation and plug it into the first.
[tex]c + a = 177[/tex]
[tex]c = 177 - a[/tex]
Plug it in:
[tex]6(177 - a) + 9.6a = 1350[/tex]
[tex]1062 - 6a + 9.6a = 1350[/tex]
[tex]1062 + 3.6a = 1350[/tex]
[tex]3.6a = 288[/tex]
[tex]a = 80[/tex]
Now, plug in 80 for "a" in either of the equations to find "c."
[tex]c + (80) = 177[/tex]
[tex]c = 97[/tex]
Rather than solving algebraically, as shown above, you can also graph the two equations, and wherever they intersect will be the solution.

1. Eighty-nine percent of Americans polled are in favor of arts education being taught in public
schools.
a. Does the above numerical value describe a parameter or a statistic?
b. After reading the above statement, you decide to campaign for the arts in education and
use the statement: "A majority of Americans are in favor of art education, which shows
their love of arts. Americans support ballet teaching in public schools." What branch of
statistics would you be applying?
Answer:
a. parameter
b. descriptive statistics
Step-by-step explanation:
The values of the population charactersitics are summarized by certain numerical descriptive measures called parameters.
The observations composing a sample are used to calculate a corresponding numerical descriptive measure called a statistic.
a. The percent of Americans is of a population and therefore it is a parameter not a statistics.
b. Descriptive statistics deals with the collection, summarization and display of data.
Inferential statistics deals with conclusions drawn based on a sample.
This is descriptive statistics because it is displaying of data collected from a population of America.
an 8 inch wide photo has been reduced to a 5 inch wide by 7 inch tall photo. How tall was the original photo?
Answer:
It was 10inches tall
Step-by-step explanation:
If the width was 8 inches tall but then was reduced to 5 inches tall that means it was reduced by 3 inches, so we just do the same thing with the height. If it is 7inches tall after it was reduced then just add 3 inches back to it which means it was 10 inches tall...Ik its kinda confusing but its correct

the product of the ages of a father and his son is 576.if the father is 18 years younger than 5 times his son .how old is each?
Answer:
[tex]F = 45.4[/tex]
[tex]S = 12.68[/tex]
Step-by-step explanation:
Given
Represent the sons age with S and the father's age with F
[tex]S * F = 576[/tex]
[tex]F = 5S - 18[/tex]
Required
Determine F and S
Substitute 5S - 18 for F in the first equation
[tex]S * (5S - 18) = 576[/tex]
Open Bracket
[tex]5S\² - 18S = 576[/tex]
Equate to 0
[tex]5S\² - 18S - 576 = 0[/tex]
Solve using quadratic formula:
[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 5[/tex]
[tex]b = -18[/tex]
[tex]c = -576[/tex]
[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]S = \frac{-(-18)\±\sqrt{(-18)^2 - 4*5*-576}}{2 * 5}[/tex]
[tex]S = \frac{18\±\sqrt{324 + 11520}}{10}[/tex]
[tex]S = \frac{18\±\sqrt{11844}}{10}[/tex]
[tex]S = \frac{18\±\108.8}{10}[/tex]
[tex]S = \frac{18+108.8}{10}[/tex] or [tex]S = \frac{18-108.8}{10}[/tex]
[tex]S = \frac{126.8}{10}[/tex] or [tex]S = \frac{-90.8}{10}[/tex]
[tex]S = 12.68[/tex] or [tex]S = -9.08[/tex]
Since, age can't be negative.
We have that:
[tex]S = 12.68[/tex]
Recall that:
[tex]F = 5S - 18[/tex]
[tex]F = 5 * 12.68 - 18[/tex]
[tex]F = 45.4[/tex]
Hence:
The father is 45 years old and the son is 13 years old (Approximated)
What is the value of x?
45°
(2x - 5)°
Answer:
x=70
Step-by-step explanation:
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Divide 140 by 2 to get X=70
f(x)=6x+14 g(x)=2x-6 find f(x)+g(x)
