First, subtract 7 from both sides.
8a=24
Then, divide each side by 8.
a=3
I have to form a couple of equations in order to solve it.
let the amount of soybean in the mixture be x and that of cornmeal be y
Step-by-step explanation:
x+y = 280
y = 280 - x
x*(14/100) + y*(7/100) = 280*(12/100)
Multiplying the whole equation by 100;
14x + 7y = 3360
in this equation,put y = 280 - x
14x +7 (280-x) = 3360
14x +1960 - 7x = 3360
14x - 7x = 3360 - 1960
7x = 1400
x = 200lbs
y = 280 - x
= 280 - 200
= 80 lbs
Inorder to make a 280lbs mixture having 12% protein, we should mix 200lbs of soyabean and 80 lbs of cornmeal
<span>The unit for potential energy per unit charge, or voltage, is the volt, which has the symbol "V." It takes its name from the Italian physicist Alessandro Volta, credited with inventing one of the first electric batteries.Voltage refers to the work that would be necessary for each unit charge against the existing electric field to move a charge from Point A to Point B. One volt is the equivalent of multiplying one ampere (a unit of current) by one ohm (a unit of resistance). To get the power in terms of watts, it is necessary to multiply the voltage by the current in amps.</span>
Answer:
30000000 + 400000 + 20000 + 2000 + 200
Step-by-step explanation:
Answer:
x has a value of 71, making D the correct answer.
Step-by-step explanation:
Because this is an isosceles triangle, we know that the bottom two angles are equal. We also know that the sum of the angles inside a triangle will always come to 180°. With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.
So the correct answer is D, 71 degrees.
