The answer is B. To see this visually, you have to plot the points on a graph.
Answer:
x = 57.2
Step-by-step explanation:
Equation:
32.8 + x = 90
x = 90 - 32.8
x = 57.2
<span> The geometric mean of two non negative numbers x and y is √(xy). (mean square root of XY)
So the geometric mean of 2/3 and 27/40 is
√(2/3 * 27/40)
= √(54 / 120)
= √(27 / 60)
= √(9 / 20)
= 3 / √20
= 3 / 2√5
= 3√5 / 10. </span>
Answer:
a + c = 150
Step-by-step explanation:
adults + children = 150
a + c = 150
so to find the number of adults we need to subtract the number of children from the total number of attendees.
a + c - c = 150 - c the the number of adults is
a = 150 - c
$6.40
All beads and pendants = $19.20, and the beads equal $12.80, so 12.80 + ? = 19.20. So you would use the equation. 19.20 - 12.80, which equals 6.40.
