The simplest I can put it
10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)
5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places
Same works for numbers smaller than zero
5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places
Answer:
1. 0.05x90
2. 4.5
Step-by-step explanation:
1. 0.05(50+40)
50+40=90
0.05x90
2. 0.05(50)+0.05(40)
0.05x50= 2.5
0.05x40= 2
2.5+2= 4.5
That all i could do sorry but I hope this helps
If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular.
Both exterior and interior angles sum up from 90 - 180 degrees. Therefore, if an exterior angle is perpendicular, then the interior angle must also be perpendicular in order for them to sum up to that amount of degrees (90 - 180).
Answer:
a=4
Step-by-step explanation:
combine like terms
8a-4=36
add on both sides
8a-4+4=36+4
8a=32
divide
a=32/8
a=4
Answer: -8y+12
Step-by-step explanation: Multiply using the distributive property.
