Write the ratio 9:4 in the form n: 1
The ratio 9:4 in the form n:1 is 2.25:1.
The given ratio is 9:4.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
We need to write the given ratio in the form n:1
Divide the given ratio by 4
9/4 : 4/4
⇒ 2.25:1
Therefore, the ratio 9:4 in the form n:1 is 2.25:1.

Greta is opening a savings account. She starts with $100 and plans to add $50 each week. How do you write an equation she can use to calculate the amount of money she have after any number of weeks. How much money will she have after 1 year?- what is the unit rate of change for this situation
Answer:
100+50n
n stands for the number of weeks
There are about 52 weeks in a year, so
100+50(52) = 2700
Greta would have $2700 after 1 year

Find all real and complex roots of the function. The Zeros are:
List the zeros as complex numbers. Separate answers by commas as needed.
Answer:
1 ; -2·i ; 2·i
Because x = -1 is a real root, you can divide
(x^3 + x^2 + 4·x + 4)/(x + 1) = x^2 + 4
Roots of x^2 + 4 are
x^2 + 4 = 0
x^2 = -4
x = ± 2·i
All real and complex roots are

Determine which integer(s) from the set S:{−40, 2, 20, 42} will make the inequality three eighths m minus three is less than one fourth m plus 2 false.
Answer:
{-40, 2}
Step-by-step explanation:
Part A: -40/8 x 3/8 would be
120/8 but then we have to subtract it from 3
that would be 117/8 then we simplify it 14 -5/8.
Part B: first it would be 2 plus 2 and that's 4 and then make 4 into a fraction
4/4 we simplify that 1 0/4.
14 -5/8 < 1 0/4.

Find WI if IE = 3
EW and YG are medians of XYW
Based on the definition of the median and applying the centroid theorem, the length of WI is calculated as: 6 units.
What is the Median of a Triangle?The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.
Medians intersect each other at a point inside the triangle that is called the centroid. Based on the centroid theorem, since J is the centroid of triangle XYW, then:
the length of IE is one-third of the length of segment EW (referring to the image given in the question that shows triangle XYW)
Thus, we have the equation that relates the length of the segments as shown below:
IE = 1/3(EW)
Given that:
IE = 3 units
Substitute the value of IE into the equation:
3 = 1/3(EW)
3(3) = EW
9 = EW
EW = 9 units
Therefore:
Length of WI = the length of EW - the length of IE
Substitute
Length of WI = 9 - 3
Length of WI = 6 units.

4) A group entering a zoo purchased 33 admission tickets for a total of $139.50. Adult tickets (x) cost $7.50 and
tickets for children (y) cost $3.50. How many of each type of ticket were purchased?
/5 points
The number or children tickets are 24 and adults tickets are 9.
How to illustrate the information?Adult tickets (x) cost $7.50 and tickets for children (y) cost $3.50. The equation will be:
7.5x + 3.5y = 139.5
There are 33 tickets. This will be:
x + y = 33
x = 33 - y.
Recall 7.5x + 3.5y = 139.5
Substitute for x.
7.5(33 - y) + 3.5y = 139.5
247.5 - 7.5y + 3.5y = 139.5
-4.5y = 139.5 - 247.5
4.5y = 108
y = 108/4.5
y = 24
Number of children ticket = 24
Adult tickets = 33 - 24 = 9

The hypotenuse is the longest side of a triangle. It is ALWAYS the one across from the right angle (depicted as the box in the corner at 90 degrees). Therefore the 2 sides that intersect the 90-degree angle are "leg" and "leg" and the longest side is the"hypotenuse"
2)
The Pythagorean theorem states: [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are sides and c is the hypotenuse.
[tex]a^{2} + b^{2} = c^{2} \\8^{2} + 6^{2} = c^{2} \\64 + 36 = c^{2} \\100 = c^{2} \\\sqrt{100} = c\\10 = c[/tex]
For your purposes, a and b do not matter which number you choose as long as you make sure that they are sides and not the hypotenuse.
3)
The Pythagorean theorem states: [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are sides and c is the hypotenuse.
[tex]a^{2} + b^{2} = c^{2} \\4^{2} + 7^{2} = c^{2} \\16 + 49= c^{2} \\65 = c^{2} \\\sqrt{65} = c\\8.0622 = c[/tex]

Aisha went shopping for a new pair of sneakers. The listed price of the pair of

The percent sales tax of the purchase is 3 %.
How to find percent sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
She went shopping for a new pair of sneakers.
The listed price of the pair of sneakers was $43, but the price with tax came to $44.29.
Therefore, the percent sales tax can be found as follows:
sales tax = 44.29 - 43
sales tax = $1.29
Therefore,
percent sale tax = sale tax / cost with tax × 100
percent sale tax = 1.29 / 43 × 100
percent sale tax = 129 / 43
Therefore,
percent sale tax = 3%

8 × [tex]10^5[/tex] is 200 times greater than 4 × [tex]10^3[/tex] as according to multiplying and dividing as per the scientific notation of multiplication and division.
What is scientific notation?A kind of representation of number which is some power of 1/10 can also be expressed in as easily in scientific notation.
1/10 = [tex]10^{-1[/tex] (“ten to the minus one power”)
More generally, the expression “[tex]10^{-n[/tex]” (where n is a whole number) means (1/10) n. Thus
[tex]10^{-3[/tex] = [tex]\frac{1}{10}^{-3}[/tex]
= 1/1000
[tex]10^{-8[/tex] = [tex]\frac{1}{10}^{-8[/tex]
= 1/100,000,000
Scientific notation was invented to help scientists (and science students) deal with very large and very small numbers, without getting lost in all the zeros.
Herein this question
8 × [tex]10^5[/tex] can also thus be written as 2 x 4 × [tex]10^5[/tex]. On dividing with 4 × [tex]10^3[/tex] we get 2 x [tex]10^2[/tex]. Thus, it is 2 x [tex]10^2[/tex] i.e., 200 times larger than 4× [tex]10^3[/tex].
The expression “10n”, where n can be stated as a whole number, simply means that “10 is raised to the nth power,” or in other words, a number that is got by using 10 as a factor n times.
You can also notice that the number of zeros that are present in the ordinary decimal expression is absolutely equal to the power to which thus 10 is raised.
If any kind of number is expressed in words, first we have to write it down as an ordinary decimal number and then we have to convert it. Thus, the value “ten million” becomes 10,000,000. There are a total of seven zeros, so in powers of ten notation ten million is written [tex]10^7[/tex].
