. Evan ran 93 miles in one hour and twenty-
four minutes. Find the average number of
minutes it took him to complete one mile.
Answer:
0.903 minutes / mile
Step-by-step explanation:
For this question we can use the rationing method to solve.
Given information from the question:
93 miles = 1 hour 24 minutes
93 miles = 84 minutes
1 mile = 84 minutes ÷ 93 miles = 0.903 minutes / mile (rounded to 3 s.f)

Mackenzie needed to get her computer fixed. She took it to the repair store. The
technician at the store worked on the computer for 2.75 hours and charged her $181
for parts. The total was $249.75. Write and solve an equation which can be used to
determine 2, the cost of the labor per hour.
The cost of the lab per hour is $25.
How to determine the cost of the labor per hour?
Here we know that they charged a total of $249.75, and the cost in parts was $181, then the cost in labor is:
$249.75 - $181 = $68.75
And we know that they worked for 2.75 hours, the cost per hour is given by the quotient between the cost in labor and the number of hours, then we can get:
$68.75/2.75 = $25
So we can see that the cost of the lab per hour is $25.

389x89 i really Need help . Show work pls
Answer: the answer would be 34621
Step-by-step explanation:
Answer:
34,621
Step-by-step explanation:
Well as it may look hard it is simpler than you think
389*89 looks like a big number right? lets break it down into small pieces!
lets split up 389 into hundreds, tens, and ones.
So that will make it 300, 80, and 9!
Since we have to make 89 more of those numbers, lets try out a simple number in there!
Lets look at 9*89
9*9= 81
9*80=720
This means the answer is 801!
we will use this number later!
Now lets move on to 80*89!
80*9=720
80*80=6400
We will get 7120 if we add them!
we will also use that number later!
Now finally, 300*89!
300*80=24000
300*9=2700
We will get 26700!
Now finally, we add up all the three answers we got!
801 + 7120 + 26700 = 34621
This means the final answer is 34,621! I hope this helps!

In irrational number theory, the integers are sometimes qualified as rational integers to differentiate them from the more general algebraic integers. In fact, (rational) integers are algebraic integers that also are rational numbers.An integer is that the number zero, a positive number or a negative integer with a minus sign. The negative numbers are the additive inverses of the corresponding positive numbers.integer, whole-valued positive or negative number or 0. The integers are generated from the set of counting numbers 1, 2, 3,… and therefore the operation of subtraction.

The difference between 9493 take away 2324
Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us by how much a number differs from the other. The aim of finding the difference in math is to tell how many numbers lie between the two given numbers.
Set difference is a generalization of the idea of the complement of a set and as such is sometimes called the relative complement of T with respect to S. The symmetric difference between two sets S and T is the union of S – T and T – S.
Based on the conditions, formulate :
Let us assume,
The difference between value = x
We can write,
x = 9493 - 2324
Calculate the sum or difference,
x = 7169.

Identify the function family to which f(x)=x+3 belongs.
A. Constant B. Linear C. Absolute value D. Quadratic
The function f(x)=x+3 belongs to linear category.
For a function to be linear it must have an single variable and also the maximum power to that variable in the equation must be 1.
In a linear variable there is always single value possible in a equation.
In the function also there is only one value at one time but it varies according to the function change.
Here the function f(x)=x+3 will vary as the value of x changes.
For x=1 the value of f(1)=4
For x=2 the value of f(2)=5 and so on
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Find the measure of the angle AEC that is supplementary to the angle AED in the diagram below. Enter only the number.
The measure of angle AEC is 115°.
What are Supplementary angle?
Supplementary angle are those angles whose sum up are 180 degree.
Given that;
Measure of angle AED = 65
The angle AEC is supplementary to the angle AED.
Now, The angle AEC is supplementary to the angle AED.
Hence, ∠ AEC + ∠AED = 180°
Since, Measure of angle AED = 65°
So, ∠ AEC + ∠AED = 180°
⇒ ∠ AEC + 65° = 180°
⇒ ∠ AEC = 180° - 65°
⇒ ∠ AEC = 115°
Therefore, The measure of angle AEC is 115°.

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
From the given information:
A bag 2 contains 2 red marbles, 2 green marbles, and 4 blue marbles.If we choose a marble, then another marble without putting the first one back in the bag.
Then
A bag contains 2+2+4=8 marbles in total.
We have to search out the probability of the subsequent events:
1. we've to settle on a red marble from the bag that contains 8 marbles in total, 2 of them are red
2. we've to decide on a green marble from the bag that contains 7 marbles in total, 2 of them are green.
The probability of the primary event to happens is:
P(one) = 2/8 = 1/4.
The probability of the second event to happen is:
P(two) = 2/7
The probability of both events to happen is:
P = P(one) * P(two)
P = 1/4 * 2/7
P = 1/14
P = 0.0714.
