Answer:
323
Step-by-step explanation:
set up a table (multiply across and add down - <em>don't add the middle column). Use the equation created by the "Total" row to solve for the variable.</em>
Quantity (times) % equals Total
Sol'n 1: x * .80 = (x)(.8)
<u>Sol'n 2: 15 - x * .30 = (15 - x)(.3)</u>
Total: 15 * .50 = .8x + .3(15 - x)
15(.5) = .8x + 4.5 - .3x
7.5 = .5x + 4.5
3.0 = .5x
6 = x
Answer: 6 liters of 80% and 9 liters of 30%
Answer:
64 inches or 64 pulgadas
Step-by-step explanation:
The formula for the perimeter of a rhombus is given as:
P = 4a
Where a = side length of the rhombus
From the above question, side length of the rhombus = 16 inches
Hence, Perimeter of the rhombus = 4 × 16 inches
= 64 inches
La fórmula para el perímetro de un rombo se da como:
P = 4a
Donde a = longitud del lado del rombo
De la pregunta anterior, la longitud del lado del rombo = 16 pulgadas
Por lo tanto, perímetro del rombo = 4 × 16 pulgadas
= 64 pulgadas
