Answer: 175 robberies
Step-by-step explanation:
Robberies last year= 243
Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.
Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.
There are 175 robberies this year
8e^(4x)×2e^(5x-1)
16e^(4x+5x-1)
When bases are same power adds.
16e^(9x-1)
Answer:
4000
Step-by-step explanation:
500x8=4000
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
X will equal 40.
EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.
4x+20=180
subtract 29 from both sides
4x=160
divide each side by 4 so isolate x
x=40
