Answer:
B. $200,000
Step-by-step explanation:
Let x be the amount placed at 5.5%
3x is the amount placed at 5%
This leaves the rest for the 4.5 % 500000- x - 3x = 500000-4x
Assuming simple interest
I = PRT where I is interest, P is principle, rate is rate and t is time
Interest for the 5.5% for 1 year is
I = x * .055 * 1 = .055x
Interest for the 5.% for 1 year is
I = 3x * .05 * 1 = .15x
Interest for the 4.5% for 1 year is
I = 500000-4x * .045 * 1 = 22500 - 0.18 x
Add the interest together to get the income for 1 year
.055x+ .15x+22500 - 0.18 x=25,000
Combine like terms
0.025x+22500=25000
Subtract 22500
.025x =2500
Divide by .025
x =100000
short term notes is 100000
3*x = 300000 = government bonds
The rest is utility bonds 500000- 100000-300000 = 100000
We want how much more in government bond than utility bond
300000 -100000 = 200000
Answer:
0.2 or 1/5

Answer:
x = 129º
Step-by-step explanation:
It will take some time to elaborate but start this way:
you see the triangle with the 58º and 57º? Now by rule, the sum of all angles ina triangle is 180º
so 57+58 = 115
to discover the other angle you just have to 180-155 = 65
Now that you know the 65º by rule the angle facing it is exactly the same, follow from there, solve all triangles until you get to x...
Answer: A. {5, -5 }
Step-by-step explanation: I believe this is the answer because the equation split up is 3 * x² - 75 = 0 In this equation (since it equals 0) you need to find how 3x² equals 75. if you do 25, the answer of the equation will be 1875 not 75. if you do 5, it equals 75 because you have to do exponents first so 5 times it self equals 25, then 25 * 3 equals 75, Finally you get 75 - 75 = 0. Also, if your worrying is the answer A. {5,-5} or B.{5} the answer is A. because -5 times it self is also 25. Please mark Brainliest.
Answer:
x=-14
Step-by-step explanation:
-2(x-8)+4x= -12
