and brainliest for extra point this question 100 since that is my limit is that
The required equation is $650 / 17.50 = 37$ to determine the number of months and the solution to the equation is 37.
To determine the number of months it will take Erik to save the $650, we need to find out how many $17.50 increments are in $650. We can do this by dividing $650 by $17.50. This gives us 37.142. Since Erik can only save in whole dollar amounts, we can round this number down to 37.
Thus, the equation we are looking for is $650 / 17.50 = 37$, where the left side of the equation represents the total amount of money Erik wants to save, divided by the amount of money Erik saves each month. The right side of the equation represents the number of months it will take Erik to save the $650.

How do you find the maximum value of a set?
The ven diagram from set theory must be used to determine the highest value and minimum value in a set.
We're using this as an illustration.
Let A and B represent two sets with 4 and 7 items, respectively. The maximum number of elements that A and B can have is then written.
So let's assume:
A's element count is equal to n. (A).
B's element count is equal to n. (B).
The sum of the elements of A and B is n (A and B).
Now, here is the equation for the components of A U B:
n(A∪B)=n(A)+n(B)−n(A∩B)
The answer to the question states that set A's element count is four, whereas set B's element count is seven. We can thus write:
The number of elements that are included in both sets A and B is represented by the numbers n (A) = 4 and n (B) = 7.
The maximum number of elements in n(A,B) must be determined. Therefore, when n(AB) is smallest and when n(AB) is zero, n(AB) is at its maximum.
n(A∪B)=n(A)+n(B)−n(A∩B)⇒n(A∪B)=4+7−0⇒n(A∪B)=11
Hence, the maximum number of elements in A∪B is 11.
You might be asking why n (AB) must be minimized in order to be maximized, and why the minimal value of n (AB) is 0.
In the formula for n (A∪B),
n(A∪B)=n(A)+n(B)−n(A∩B)
L.H.S will be maximized when in the R.H.S; the term after minus sign will be minimized. Hence, n (A∩B) must be minimized.
The fact that n (AB) can take on any value less than 0 indicates that there are no elements in sets A or B that are shared by both sets. Furthermore, it's possible that the two sets we have don't share any elements.
When no elements is common in both the sets, the n (A∩B) is ∅.
The set which has no element in it is called a null set or an empty set.
By this we can find maximum value in a set.

How do you find the domain and range of a square root graph?
Domain and range of a square root graph is [0, ∞) and [0, ∞) respectively.
Domain of a function:
The domain of a function is the set of input values (x) for which it produces an output value.
Range of a function:
The set of all output values of a function.
Like if we consider a function [tex]y = f(x)[/tex]
then input inside function that is x is know as domain of function
output of function that is y is known as range of function.
First we write square root function as y = [tex]\sqrt{x}[/tex]
So inside root negative numbers are not allowed so value of x should be positive numbers means x>=0.
So domain of square root function [0, ∞).
Output of square root function is always positive so range of square root function is also [0,∞).

Over the two days, the group traveled an average speed of 2.79 miles per hour.
Given:
during the first leg of a backpacking trip, a group of hikers covered 10.4 miles in 3 hours and 1 minute.
he next day, the group hiked 8.6 miles in 3 hours and 47 minutes.
we are asked to find the group's average speed over the two days = ?
average speed = total distance / total time
total distance = 10.4 + 8.6 mi = 19 miles
total time = ( 181 + 227 min ) = 408 min
hence average speed = ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr
Hence we get the average speed as 2.79 miles/hour.

44. The quotient of 16 and a is greater than 4. What is a possible value of a?
A. 2
B. 4
C. -2
D. 8
E. 5
Answer:
A
Step-by-step explanation:
16 / a = x (+ r)
16 is the dividend
a is the divisor
x is the quotient
(r is the remainder, if the division is an integer division)
the smaller the divisor, the larger the quotient, of course. and vice versa.
remember, a division is the calculation how often the divisor fits into the dividend.
therefore, the smaller the divisor, the more often it fits into the dividend.
the quotient must be greater than 4. so, 4 itself is not a valid quotient for this problem.
but let's start with it :
16 / 4 = 4.
so, a = 4 (B) is not a valid solution.
to make the quotient larger (than 4), a must be smaller than 4.
the only valid solution is
A a = 2
except for C all other answer options are larger than 4 making the quotient smaller than 4.
and C is negative, which would make the quotient negative and therefore smaller than 4.
so, A is the only remaining valid answer.
16/2 = 8
perfect. the quotient (8) is larger than 4.

Find the missing side of the triangle.
X
8.3 m
5.9 m
The missing side of the triangle is approximately 10.2 m. This solution assumes that the given sides form a right triangle.
How to find side of triangle ?To find the missing side of a triangle, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
The formula for the Pythagorean theorem is:
a^2 + b^2 = c^2
where a and b are the lengths of the two sides of the triangle and c is the length of the hypotenuse.
The lengths of two sides of the triangle, 8.3 m and 5.9 m, and you need to find the length of the third side (the hypotenuse).
You can use the Pythagorean theorem to solve for the missing side as follows:
c^2 = a^2 + b^2
c^2 = 8.3^2 + 5.9^2
c = sqrt(8.3^2 + 5.9^2)
c = sqrt(69.29 + 34.81)
c = sqrt(104.1)
c = 10.2 m
Therefore, the missing side of the triangle is approximately 10.2 m.
This solution assumes that the given sides form a right triangle. If the triangle is not a right triangle, the Pythagorean theorem may not be applicable and a different method may be needed to find the missing side.

The minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.
What is the mean?
Mean, in terms of math, is the total added values of all the data in a set divided by the number of data in the set.Given:
Standard deviation, σ = 2points
Confidence level = 90%
Sample mean, ε = 1 point
At 90% confidence level
1 - α = 0.90
α = 1 -0.90
α = 0.10
α/2 = 0.05
Zα / 2 = Z₀.₀₅

a family of four went out to dinner. the cost of their meal was $75.99. Tax on the meal is 6.75% and they left a 19% tip on the cost of the meal. what is the total amount they will pay
The total amount they will pay = $95.557
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.
Cost of meal = $75.99
tax amount = 6.75% of 75.99
= ( 6.75/100 ) * 75.99
= $5.129
Tip amount = 19% of 75.99
= (19/100)*75.99
= $14.438
Total amount they will pay = $75.99 + $5.129 + $14.438 = $95.557
