Donna took twice as long to drive 720 miles and Maple took to drive 200 miles. Find the rates and ties of both if Donna's speed
shepuryov [24]

Answer:

Donna traveled for 8 hours at 90 mph

Maple traveled for 4 hours at 50 mph

Step-by-step explanation:

The velocity at which each person traveled is given by the distance traveled divided by the time spent (t). From the information given, the following expressions can be written

t_d = 2t_m\\V_d = V_m+40\\V_d = \frac{720}{t_d}\\V_m = \frac{200}{t_m}\\\\V_d = \frac{360}{t_m}\\ \frac{360}{t_m}=\frac{200}{t_m}+40\\t_m = 4\ hours\\t_d=2*4 = 8\ hours\\\\V_d = \frac{720}{8}=90\ mph\\V_m = \frac{200}{4}=50\ mph\\

Therefore, Donna traveled for 8 hours at 90 mph and Maple traveled for 4 hours at 50 mph.

Consider a gene with four alleles a1, a2, a3, and a4. if the cross a1a2 × a3a4 yields two offspring, what is the probability tha
mylen [45]
Possible genetic combinations of offspring are:
<span>
- A1A3
- A2A3
- A1A4
- A2A4
</span>

Therefore, each genotype has a probability of 1/4

The probability of having thesame genotype the second time is 1/4 * 1/4

= 1/16

The probability that both offsprings will have the same genotype is 1/16
