As we know a percentage is out of a hundred so we would start of by dividing by 100, if the percent is not a whole number then multiply both the bottom and top number by 10 for every number after the decimal point
Number 7 is 16 and #6 is 29
and 8 is 45
Answer:
a1 = 0.5; common ratio = 5
Step-by-step explanation:
Let the common ratio = r
a2 = 2.5
a3 = 2.5r
a4 = 2.5r * r = 2.5r^2
We are told a4 = 62.5, so
2.5r^2 = 62.5
Divide both sides by 2.5
r^2 = 25
r = 5
a2 = a1 * r
a1 = a2/r = 2.5/5 = 0.5
Answer: a1 = 0.5; common ratio = 5
If K=C+273.15
and in a. C=200° then K=200+273.15
Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps
