Answer:
a)
_b+_=_
6B+3=75
B)
He ordered 12 books
Step-by-step explanation:
so each book (b) costs $6. he payed $75 total including the $3 shipping price
That gets us:
6b+3=75
6b=72
b=12
Therefore, Tom ordered 12 books
79.57 times 12% = 70.02
70.02 times 7.75% = 5.43
70.02 plus 5.43 = 75.43
Answer:
DOMAIN - 20
RANGE - 10
Step-by-step explanation:
Answer:
the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.
Step-by-step explanation:
Allele frequency is how often an allele occurs in a gene pool relative to the other alleles for that gene
<u>Genotype</u> <u> No. of Individuals</u><u> </u> <u>No. of Allele </u><u>B</u> <u>No. of Allele</u><u> b </u>
BB 30 30*2 =60 30*0 =0
Bb 10 10*1 =10 10*1=10
bb 10 10 *0 =0 10*2=20
Total 50 70 30
Total no. of alleles = 70+30 =100
The frequency of allele B :
:
:
The frequency of allele b :
:
:
Hence the frequency of allele B is 0.7 and allele b is 0.3 in population’s gene pool.
Answer:
16 oil changes
Step-by-step explanation:
You can write this into ratio form to help explain this. The ratio 4:2 can be used to explain this problem with the 4 meaning 4 oil changes and the 2 meaning after every two hours. You want to make it to where the 2 hours is at 8 hours so you would multiply 4 on both sides of the ratio which will give you the new ratio of 16:8. The mechanic can do 16 oil changes within 8 hours.
