Answer:
2520ft
Step-by-step explanation:
Calculation for what is the scale of the model?
Let x will be the span length
Hence,
x= 4200 feet long/20 inches long
x=210
Thus:
1 inch = 210 ft
1 ft = 2520
=2520ft
Therefore the scale of the model will be 2520ft
Answer:
The answer is 5,030 feet.
Step-by-step explanation:
It is stated that his starting point is at an elevation of 0 feet. He climbs 3.200 feet on the first day and then adds another 1.830 feet on the second day. This makes his total elevation 3,200 + 1,830 = 5.030 feet.
As he reaches the other side of the island on the 3rd day which is at an elevation of 0 feet as well, he loses all the elevation he gained on days 1 and 2, which is 5,030 feet.
I hope this answer helps.
17,900 x 0.1296 = 2318.05
2318.05 should be subtracted from 17,900 and it should be somewhere around 15,581.95
The answer is -14
Explanation:
x - 8 = 2x + 6
We move all term to the left
x - 8 - ( 2x + 6 ) = 0
We get rid of parentheses
x - 2x - 6 - 8 = 0
We add all the numbers together, and all the variables
-1x - 14 = 0
We move all terms containing x to the left, all other term to the right
-x = 14
x = 14/-1
x = -14
Answer:
19
Step-by-step explanation:
given:
f(x)=3x²-8
g(x)=4x+1
g(-1) = 4(-1)+1
g(-1) = -4 + 1
g(-1) = -3
hence
f[g(-1)]
= f(-3)
= 3(-3)²-8
= 3(9) - 8
= 19
