Answer:
GCF
Step-by-step explanation:
Each row will have the same number of plants. So we want to know what's the biggest number we can divide 45, 81, and 63 by. That means we need to find the greatest common factor. In this case, it's 9. Each row can have at most 9 seeds.
Answer:
.054 interest rate (not it percentage)
Step-by-step explanation:

A = future value: $130,000
P = principal (initial) value: $50,000
r = interest rate: unknown value
t = time: 20 years

Answer:
9.63 metres
Step-by-step explanation:
The base to height ratio =12:1
From the given ramp, Base to Height Ratio =Base:0.8
Therefore:
12:1=Base:0.8

To find the length of the ramp, we apply Pythagoras theorem in the right triangle formed.
Length of the ramp ,l

A.
Multiply the number of days, x by 50 per day to get 50x.
Next multiply the number of miles driven to the amount she gets per mile: 0.60 x 200 = $120
Now add both together to equal the total of 1620.
The equation becomes: 50x +120 = 1620
B.
50x +120 = 1620
Step 1: subtract 120 from both sides ( subtraction property of equality):
50x = 1500
Step 2: Divide both sides by 50 ( division property of equality):
x = 1500 / 50
x = 30
