Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90
Answer:
<h2>V = 729</h2>
Step-by-step explanation:
The formula of a volume of a cube with an edge <em>a</em>
<h3>

We have <em>a </em>=<em> </em>9 . Substitute:
<h3>V = 9³ = 9 · 9 · 9 = 729</h3>
Answer:
Step-by-step explanation:
Act like it's a whole circle and find the perimeter, then divide by 2.
P = 2 * pi * r
P = 2 * 3.14 * 9
P = 56.52
Now divide by 2:
P = 28.26
