3. ΔBDE ~ ΔBCF
4. BF/BC = BE/BD
5. 254/BC = 160/457
.. BC = 254*457/160 ≈ 725 units
Pru, Piper, Phoebe......ratio 5:3:4...added = 12
what this means is Pru has 5/12 of the total amount, Piper has 3/12 of the total amount, and Phoebe has 4/12 of the total amount
pru = piper + 24
5/12x = 3/12x + 24
5/12x - 3/12x = 24
2/12x = 24
x = 24 / (1/6)
x = 24 * 6
x = 144 spices in total
pru has : 5/12(144) = 720/12 = 60 spices
piper has : 3/12(144) = 432/12 = 36 spices
phoebe has : 4/12(144) = 576/12 = 48 spices <====
I'm pretty sure your answer is (a) (-2, 3)
I hope this helps and have a nice day!
And please mark me as brainliest!!
Answer:
Step-by-step explanation:
The formula primarily used for finding the derivative of a square root is
d/dx(x^n) = nx^(n - 1)
and so:
(d/dx)(x^(1/2)) = (1/2)x^(1/2 - 1), or:
1
(1/2)x^(-1/2), or, in radical form, ---------
2√x
Answer:
28.5 units²
Step-by-step explanation:
Shape 1 - ( length * width ) 3*5 = 15
Shape 2 - ( length * width ) 3*3 = 9
Shape 3 - ( height * base / 2 ) 3*1.5 = 4.5
