Draw a diagram to illustrate problem as shown below.
Let h = the height of the tree.
Because ΔABC ~ ΔADE, therefore
DE/BC = AD/AB
That is,
h/1.94 = (5.1 + 10.2)/5.1 = 3
h = 1.94*3 = 5.82 m
Answer: 5.82 m
To find the unit rate in cost per hour, you will write the amount of money over the total time for each class. Then divide the cost by the time to find the unit rate.
New Steps: $7.50/1.5 hours = $5 per hour
Stepping High: $6.50/1.25 hours = $5.20 per hour
8x - 6 - 12x^2 + 9x
2(4x-3)-3x(3x-3)
=> (2-3x)(3x-3)
=> 3(x-1)(2-3x)
Answer:
idk try to figure it pouy
Step-by-step explanation:
2x - 15
15 is decreased that is the key word here which indicates subtraction.
twice a number with given variable x is 2x
subtraction always goes behind so 2x - 15
