So simply we are putting values in equation
A2 A=2.3
So A2 means 2.3 × 2.3
The answer is 5.29
Answer:
Step-by-step explanation:
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians and engineers, in part ... mode on scientific calculators) differs from normalized scientific notation in that the exponent n is restricted to multiples of 3.
Answer: 8112
I'm not sure if this is the right answer .
The team has played 24 home games.
Let h be the number of home games and a be the number of away games. The total number of games is 49; this gives ush+a=49
They won 2/3 of the home games and 2/5 of the away games; there were 26 games won. This gives us2/3h + 2/5a = 26
In the first equation we isolate h by subtracting a from both sides:h+a-a=49-ah=49-a
Substitute this into the second equation:2/3(49-a)+2/5a = 26
Using the distributive property, we have2/3*49 - 2/3*a + 2/5a = 2698/3 - 2/3a + 2/5a = 26
Finding a common denominator to combine like terms, we have98/3 - 10/15a + 6/15a = 2698/3 - 4/15a = 26
We want to convert the whole number to thirds as well; 26 = 26*3/3 = 78/3:98/3 - 4/15a = 78/3
Subtracting 98/3 from both sides:98/3 - 4/15a - 98/3 = 78/3 - 98/3-4/15a = -20/3
Divide both sides by -4/15:a = -20/3 ÷ -4/15a = -20/3 × - 15/4 = 300/12 = 25
There were 25 away games.
This means there were 49-25 = 24 home games.
1.
Storing milk at temperatures smaller than 35°F can affect its quality of taste.
hence t > 35°F
storing milk at temperatures greater than 40°F is an unsafe food practice. hence
t < 40°F
so correct choice is
C. t > 35 AND t < 40
2.
15| x-7|+4=10|x-7|+4
subtracting 4 both side
15| x-7|+4- 4 =10|x-7|+4 - 4
15| x-7| = 10|x-7|
this is possible when |x-7| = 0
hence x - 7 = 0
x = 7
hence correct choice is
C. only x=7
3.
|x+1|+5=2
we know that , |x+1| ≥ 0
adding 5 both side
|x+1| + 5 ≥ 0 + 5
|x+1| + 5 ≥ 5
hence the relation |x+1|+5=2 is false.
C. no solution
|4x+12|=0
4x+12 = 0
x = -12/4
x = - 3
hence B. solution
|3x|=9
3x = 
9
x = 9/3
x = 3
hence
A. two solutions
