Answer:
6.1 in
Step-by-step explanation:
√37=6.08276
6.1 in
The side of the square poster will be 6.1 in.
What is the area of the square?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square. For the square, all the sides are equal to each other.
Given that the area of a square poster is 37 square inches the value of one side will be calculated by using the area formula:-
Area of square = Side²
Side²= √37
Side² = 6.08276
Therefore, the side of the square poster will be 6.1 in.

What is an Equation?
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.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
f ( x ) = 2,708.92(1.12) - 12
On simplifying the equation , we get
To find the initial amount , substitute x = 0
when x = 0
Substitute the value of x in equation , we get
f ( 0 ) = 2708.92 ( 0 ) - 12
f ( 0 ) = -12
Therefore , the initial amount is -12
Hence , the value of the equation f ( 0 ) ≠ 2,708.92

What is the inverse of f(x) = 1/3 x +2
Answer:
The inverse of this function is f(x) = 3x - 6.
You can find the inverse of any function by switching the f(x) and x values. Once you've done that, solve for the new f(x). The result will be the inverse function. The step-by-step process is below.
f(x) = 1/3x + 2 ---> Switch f(x) and x values
x = 1/3f(x) + 2 ---> Subtract 2 from both sides
x - 2 = 1/3f(x) ----> Multiply both sides by 3
3(x - 2) = f(x) ----> Distribute the 3
3x - 6 = f(x) ----> Place in the proper order for formatting purposes
f(x) = 3x - 6
And that is your inverse function.

Formula for the term of a geometric sequences has been defined as,
"Each number is 4 less than 3 times the previous numbers"

Felipe made sand art bottles to sell at his school's craft fair. He wanted to use 9 different colors of sand. So, he bought 1 pound of each color. Then, he filled as many 6-ounce bottles as he could. How many sand art bottles did Felipe make?
Answer: Felipe made 24 sand art bottles.
Step-by-step explanation:
Given: Total different colors of sand = 9
Weight of each color sand = 1 pound
Then, the weight of all 9 colors would be 9 × 1 = 9 pounds
Since 1 pound = 16 ounces
Then, 9 pounds = 9 × 16 = 144 ounces
capacity of each bottle = 6 ounce
Then, the number of bottles required = ( 144 ounces) ÷ 6
= 24
Hence, Felipe made 24 sand art bottles.
Answer:

Answer:
3. Standard deviation is the square root of the variance.
4. Standard deviation is useful because it has the same units as the underlying data.
Step-by-step explanation:
3. In statistics, the dispersion in a given data with respect to its mean distribution can be determined or measured by standard deviation and variance. The standard deviation of a distribution can also be determined as the square root of variance.
4. Standard deviation is measured in the same units as that of the original data. Thus it has the same units as the underlying data.

Loop
Answer: 3 × 10⁴ miles²
Step-by-step explanation:
Given that:
Estimated Surface area of Lake = 30,000 square miles
Expressing the estimated area as a whole number multiplied by a power of ten
Hence, we are required to express the surface area in standard form:
30,000 miles ² in standard format:
30,000 is equivalent to (3 × 10,000)
3 is a whole number
10,000 = (10 * 10 * 10 * 10)= 4 th power of 10
10,000 = (10 * 10 * 10 * 10) = 10⁴
Hence,
3 × (10 * 10 * 10 * 10) = 3 × 10⁴ miles²
2. Multiply : 7/8÷40
Step-by-step explanation:

7/8 x 40 = 35
Answer:
The numbers in 7/8 divided by 40 are labeled below:
7 = numerator
8 = denominator
40 = whole number
To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:
7
8 x 40
=

A leaf fell into a river and traveled 140 meters in 4 minutes.
How many meters did the leaf travel per minute?
Answer:
35
Step-by-step explanation:
140 divided by 4 is 30
We are being told that:
A leaf fell in the river:
traveled a distance of = 140 meterstime (t) = 4 minutesWe are to determine how many meters the leaf travel per minute.
SO;
If 140 meters = 4 minutesLet the number of meters he traveled in one minute be (x).
i.e.
(x) meters = 1 minutes∴
140 meters = 4 minutes
x meters = 1 minutes
By cross multiply and making x the subject of the formula; we have:
[tex]\mathbf{(x) meters = \dfrac{140 meters \times 1 minute}{ 4 minutes}}[/tex]
x = 35 meters
Therefore, we can conclude that the leaf travels a distance of 35 meters per minute.
