Dante runs 7 miles in 60 minutes. At the same rate, how many miles would he run in 24 minutes?
Step-by-step:
We can write it in the proportion [tex]\frac{7}{60} = \frac{x}{24}[/tex]
where x is our number of miles trying to find
We now cross multiply or use the butterfly method which I will demonstrate both
Cross MultiplyWe multiply the numerator with the dominator
so [tex]7 multiplied by 24[/tex]
and [tex]60 multiplied by x[/tex]
[tex]7*24=60x[/tex]
[tex]168=60x[/tex]
[tex]\frac{168}{60} =\frac{60x}{60}[/tex]
[tex]2.8=x[/tex] or [tex]x=2.8[/tex]
Now for the
Butterfly MethodYou would do 7 times 24 divided by 60 or [tex]\frac{7*24}{60}[/tex]
Then[tex]\frac{168}{60}[/tex] simplify
[tex]2.8[/tex] so 2.8 miles in either method

The mean of 4 numbers is 40, what is the sum of the 4 numbers
Answer:
the sum of 4 numbers is 160
Step-by-step explanation:
Let 4 numbers be a, b, c, d
Mean of those 4 numbers is: (a+b+c+d) : 4 = 40
So the sum of 4 numbers is: (a+b+c+d) = 40 x 4 = 160
=> 160 is the sum of 4 numbers

which is the equation of a line that has a slope of -2/3 and passes through point (-3, -1)?
Answer: y = (-2/3)x - 3
Step-by-step explanation:
We'll be using y = mx + b
m = slope
b = y-intercept
Because we know this line will pass through -3, -1, we can input that.
y = mx + b
-1 = (-2/3)(-3) + b
-1 = 2 + b
b = -3
We can input that now to get the equation
y = (-2/3)x - 3

La función de costos para una compañía es C=125q + 13500 y su punto de equilibrio es q=270. Plantear la función de Utilidad
Based on the information given, the total cost incurred based on the equation given as C= 125q + 13500 will be 47250.
From the information given, the cost function is given as C=125q + 13500 while the value of q is given as 270. Therefore, on order to find the cost, we'll slot in the value of q into the equation given. This will be:
C=125q + 13500
C = 125(270) + 13500
C = 33750 + 13500
C = 47250
In conclusion, the cost is 47250.

If the function f (x) is defined by f(x) =x over 2 minus 6
Depending on how it is written, it could be either of these following solutions:
f(x) = x/2 - 6 or f(x) = x/(2-6)
For the first, we solve for x by replacing f(x) with 0
x/2 - 6 = 0
x/2 = 6
x = 3
For the second, do the same
x/(2-6) = 0
x/-4 = 0
x = 0

Hope it Helps you!!Harry is paid £8.60 per hour for the first 30 hours he works each week. After 30 hours he is paid 1 and a half times the hourly rate.
Last week Harry worked 33 hours. He was also paid a bonus of 1/10 of his earnings
Calculate how much in total Harry was paid last week
Answer:
1404.81
Step-by-step explanation:
1277.1 +127.71 = i read it wrong the first time sorry
The total amount paid to harry in past week, is 299.28.
What is amount?Amount is the sum or the total value.
For example, if A purchase 2 kg rice at the price of 40 rs/kg, the amount will be 40×2= 80 rs.
Given that,
The amount paid to Harry for 1 hour = $8.60
Since, Harry worked for 33 hours,
So, The amount paid to Harry for 33 hours = 8.60×33=283.8
Harry gets half times more amount than hourly rate and also gets bonus for last 3 days
So for last 3 days the extra amount paid to Harry
= 3×1/2×8.60+3×1/10×8.60
= 12.9+2.58
=15.48
So the total amount paid to harry = 283.8+15.48=299.28
