Answer:
94 or 95
Step-by-step explanation:
91 + 95 + 87 + 83 = 356
356/4 =89
average so far is 89
356 + 94 = 450
450/5 = 90
356 + 95 = 451
451/5= 90.2
Answer:
Step-by-step explanation:
4x - 3y = 1
x + 3y = 0
Req To Solve With Elimination:
Make Them Equal:
-> 4x - 3y = 1
-> 4x + 4 . 3y = 0
Simplify:
-> 4x - 3y = 1
-> 4x + 12y = 0
-> 4x - 4x - 3y - 12y = 1
-> -3y - 12y = 1
-> -15y = 1
->
-> 
->

Answer:
10 cm³
Step-by-step explanation:
According to Archimedes, if we place an object in water, the rise of the water in mL will be the volume of the object in cm³.
Without the rock, the water measures 20 mL.
With the rock, the water measures 30 mL.
The change here is 
, so 10 cm³ is the volume of the rock.
Hope this helped!
Answer:
More milk production: Holstein Farm
About how much more: 52 gallons (approx.)
Step-by-step explanation:
<u>Looking at the table:</u>
We find the slope (gallons/number of cows) by dividing gallons with number of cows from each row to get this:
175/30 ≈ 348/60 ≈ 526/90 etc.
= 5.8
<u>Looking at the graph:</u>
We find the slope by taking 2 points from the graph and the slope would be:
Change in y coordinates/ Change in x-coordinates
Taking the 2 points:
(50,300) & (150,1000)
slope = (1000-300)/(150-50) = 700/100 = 7
<u>Lets find milk production of 2 farms:</u>
Holstein: drawing a line connecting the points and looking at x = 60, we see the gallons would be around 400.
Jersey: 60 days is 348 gallons (in table)
So, Holstein Farm would produce more milk in 2-month period.
How much more???
400 - 348 gallons ≈ <u>52 gallons (approx.)</u>
