5 hours on Monday, 4.5 hours on Tuesday, and 2.5 hours on Wednesday. What is the mean number of hours she worked over the three-day period?
Answer:
Mean = 4
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers there are)
There are 3 numbers
Mean = (5 + 4.5 + 2.5)/3
Mean = 12/3
Mean = 4
Answer:
[tex] \frac{5 + 4.5 + 2.5}{3 } = \frac{5 + 7}{3} = \frac{12}{3} = 4[/tex]
Gavin can type 3600 words in 60 minutes.
Dan can type 3850 in 70 minutes.
Colin can type 3500 words in 70 minutes.
Who types at the fastest rate of words per minute?
Answer:
Gavin
Step-by-step explanation:
Gavin: 3600 words / 60 minutes = 60 wpm
Dan: 3850 words / 70 minutes = 55 wpm
Colin: 3500 words / 70 minutes = 50 wpm
An uber charges a flat rate of $6 plus $1.25 per mile. Kayla can spend no more than $27.50. If she wants to tip her driver $4, what is the greatest number of miles she can uber? Define the Variable for situation #1 and write an equation or inequality that represents this situation using the variable
Answer:
The cost of the uber is a $6 flat rate plus $1.25 per mile.
Then if you take an uber for x miles, the cost will be:
c(x) = $1.25*x + $6
Now, in this case Kayla also wants to add a tip of $4, then the total cost will be:
c(x) = $1.25*x + $6 + $4 = $1.25*x + $10
And we have the restriction that Kalya can't spend more than $27.50
Then the cost must be equal or smaller than $27.50, we can write this as:
c(x) ≤ $27.50
$1.25*x + $10 ≤ $27.50
Whit the above equation we can find the maximum value of x if we isolate x in one side of the inequality.
$1.25*x + $10 ≤ $27.50
$1.25*x ≤ $27.50 - $10
$1.25*x ≤ $17.50
x ≤ ($17.50/$1.50)
x ≤ 11.67
So the maximum number of miles that she can travel on that uber is 11.67 miles, but in this cases we only work with whole numbers, so we should round it to the next whole number that meets the condition, which is 11.
x = 11
The maximum number of miles that she can travel on that uber is 11 miles.
Please help! I need this to pass. If you are trying to get points please just chose a different question and don't mess with mine. I am in a state of trouble and I just need a helping hand.
The answer is 41
Step-by-step explanation:
To solve this we must use the formula a^2+b^2=c^2. if we substitute in the values we get 9^2+40^2=c^2. The first variable is 81, then the b variable is 1600. The hypotenuse is the c value. 81+1600 is 1681, now we must find the square root of 1681. The answer is 41. Tell me if I'm wrong :)
please help me on this! Its due tomorrow.

- 4/9 times - 5/8 in fractions.
Answer:
5/8 x 4/9 = 20/72 as simplified as 5/18 in fraction form. 5/8 x 4/9 = 0.2778 in decimal form.
Step-by-step explanation:
The product of -4/9 and -5/8 is 5/18.
Given are two negative fractions -4/9 and -5/8, we need to find their product,
To find the product of two negative fractions, you can multiply their numerators together and their denominators together, while keeping the negative sign.
Let's find the product of -4/9 and -5/8:
Product = (-4/9) x (-5/8)
To calculate the product, multiply the numerators and denominators:
Product = (-4 x -5) / (9 x 8)
Simplifying the multiplication:
Product = 20 / 72
Now, you can simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which in this case is 4:
Product = (20/4) / (72/4)
= 5/18
Therefore, the product of -4/9 and -5/8 is 5/18.

Answer:
Linear functions have a constant rate. l, domain of all real numbers, and doesn't have a vertex.
Step-by-step explanation:
linear functions are a straight line. domain numbers can be but not limited to: -999 or 999, positive and negative numbers are included but not those with π or √ do not count because they are not real numbers. It doesn't have a vertex because it is a straight line, so therefore there is no vertex.

5(2x - 8) - 15 = 5
Show/Write the steps you would use to solve the equation.
Answer:
x=6
Step-by-step explanation:
Solve for x:
5 (2 x - 8) - 15 = 5
5 (2 x - 8) = 10 x - 40:
10 x - 40 - 15 = 5
Grouping like terms, 10 x - 40 - 15 = 10 x + (-40 - 15):
10 x + (-40 - 15) = 5
-40 - 15 = -55:
10 x + -55 = 5
Add 55 to both sides:
10 x + (55 - 55) = 55 + 5
55 - 55 = 0:
10 x = 5 + 55
5 + 55 = 60:
10 x = 60
Divide both sides of 10 x = 60 by 10:
(10 x)/10 = 60/10
10/10 = 1:
x = 60/10
The gcd of 60 and 10 is 10, so 60/10 = (10×6)/(10×1) = 10/10×6 = 6:
