Answer:
25.
Step-by-step explanation:
5 ft 7 in = 5.583 ft.
We have 2 similar triangles here.
If h is the height of the tree, then:
h / 5.583 = 18/4
h = 18*5.583/4
h = 25.12 ft
Answer: Fast
Just k1dding, in terms of setting up an equation for it, we know that 8.75 is the slope coefficient with months and 75 is the intercept.
So basically amount charged = monthly service fee(# months) + bank account base
Or with numbers
Amount charged = 8.75(num months) + 75.00
Now plug in 7 months
8.75(7)+75.00 = 61.25+75.00= $131.25.
Answer:
sorry
Step-by-step explanation:
Sorry need points
Let D = the amount of money Deanna has after x games.
We know Deanna started with $15 and she spends 0.75 per game, so we can make the following equation:
D = 15 - 0.75x
Let L = the amount of money Lisa has after x games.
We know Lisa started with $13 and she spends 0.50 per game, so we can make the following equation:
L = 13 - 0.5x
The question is asking how many games need to be played for L and D to be equal, so just equate L and D and solve for x:
D = L
15 - 0.75x = 13 - 0.5x
15 - 13 = -0.5x + 0.75x
2 = 0.25x
2 = (1/4)x
8 = x
Therefore they need to play 8 games each to have the same amount of money.
In logarithm, inverse operations are applied.
