10
Step-by-step explanation:
45-15=30
30/3=10
Answer: 90
Step-by-step explanation:
Given : The number of fertilizer types = 6
The number of temperature zones =5
The number of water treatments=3
The number of different lawn plots =
Hence, the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water treatment configuration =90
Answer:
y= -x+8
Step-by-step explanation:
slope int. form: y=mx+b
first, we need to find the slope (m)
the two points are (2,4) and (7,-1).
to find the slope we do (y2-y1)/(x2-x1)
doing this we get -5/5=-1
now we can plug in point (2,4) and the slope into y=mx+b
doing this we get:
4=-1(2)+b
4=-2+b
b=8
now we have the equation:
y= -x+8
Answer:10
Step-by-step explanation: divide 60 by 6
As they are similar figures,we can use the ratio of the side to find out the value of z.
The only side that both have the value indicated is 4 and 6,therefore we would use it to find the ratio.
The eqaution would be:
6/4 = z/8
3/2 = z/8
3×8 = 2z
z = 24/2
z = 12
Thus the value of z is 12.
Hope it helps!
