$12 each. $75 - $39 = $36. $36 divided by 3 = $12. Assuming he used all his money.
Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
Step-by-step explanation:
Jake:
Mon- 4 boxes
End of the week- 3x the boxes on Mon
3 x 4 = 12
Sally:
Mon- 2 boxes
End of the week- 4x the boxes on Mon
4 x 2 = 8
12 + 8 = 20 boxes total
To find the answer, first lets divide the width and length by the scale amount given, 2 cm.
Width: 4 cm / 2 cm = 2
Length: 6 cm / 2 cm = 3
After this, we multiply the result by the amount to scale up, in this case 4 feet.
Width: 2 * 4 = 8 feet
Length: 3 * 4 = 12 feet
Therefore the answer is the first option.
Option B:
The 12th term is 354294.
Solution:
Given data:
and 
To find 
The given sequence is a geometric sequence.
The general term of the geometric sequence is 
.
If we have 2 terms of a geometric sequence 
and 
(n > K),
then we can write the general term as 
.
Here we have and .
So, n = 7 and k = 4 ( 7 > 4)
This can be written as
Taking cube root on both sides of the equation, we get
r = 3
Hence the 12th term of the geometric sequence is 354294.
