Answer:
562.5ml
Step-by-step explanation:
using percentage multipliers you just have to do:
add 0.25 to 1 because that will make 125%
then multiply it by 450ml
450ml x 1.25 = 562.5ml
I'm guessing 99.65
1800+10%-20%-25%=99.65
but it probably wrong
Answer:
1) Answer: 3) ![~~x = -3 \pm \sqrt{7}](https://tex.z-dn.net/?f=~~x%20%3D%20-3%20%5Cpm%20%5Csqrt%7B7%7D)
2) Answer: 3) 2 and -6
Step-by-step explanation:
1)
![(x + 3)^2 = 7](https://tex.z-dn.net/?f=%20%28x%20%2B%203%29%5E2%20%3D%207%20)
![x + 3 = \pm \sqrt{7}](https://tex.z-dn.net/?f=%20x%20%2B%203%20%3D%20%5Cpm%20%5Csqrt%7B7%7D%20)
![x = -3 \pm \sqrt{7}](https://tex.z-dn.net/?f=%20x%20%3D%20-3%20%5Cpm%20%5Csqrt%7B7%7D%20)
Answer: ![3)~~x = -3 \pm \sqrt{7}](https://tex.z-dn.net/?f=%203%29~~x%20%3D%20-3%20%5Cpm%20%5Csqrt%7B7%7D%20)
2)
![2(x + 2)^2 - 4 = 28](https://tex.z-dn.net/?f=%202%28x%20%2B%202%29%5E2%20-%204%20%3D%2028%20)
![2(x + 2)^2 = 32](https://tex.z-dn.net/?f=%202%28x%20%2B%202%29%5E2%20%3D%2032%20)
![(x + 2)^2 = 16](https://tex.z-dn.net/?f=%20%28x%20%2B%202%29%5E2%20%3D%2016%20)
![x + 2 = \pm \sqrt{16}](https://tex.z-dn.net/?f=%20x%20%2B%202%20%3D%20%5Cpm%20%5Csqrt%7B16%7D%20)
![x + 2 = \pm 4](https://tex.z-dn.net/?f=%20x%20%2B%202%20%3D%20%5Cpm%204%20)
or ![x + 2 = -4](https://tex.z-dn.net/?f=%20x%20%2B%202%20%3D%20-4%20)
or ![x = -6](https://tex.z-dn.net/?f=%20x%20%3D%20-6%20)
Answer: x = 2 or x = -6
Answer: Not positive that this is right but here is what I got.
Step-by-step explanation:
Set up the composite result function.
g
(
f
)(
x
)
Evaluate g(f)(x) by substituting in the value f into g
(2x - 3) + 1
Add -3 and 1
g
(
2
x
−
3
)
=
2
x
−
2
Answer:
55 degrees
Step-by-step explanation:
Looking you can see these two angles are parallel. Knowing that, since angle GHE is 55 DEC must be 55 also.
