2.5 miles per hour because you have to divide to know per hour.
10/4=2.5
Done :)
C=chicken
p=pigs
c+p=13~p=13-c (plug in)
2c+4p=40
2c+4(13-c)=40
2c+52-4c=40
-2c=-12
c=6
6+p=13
p=7
6 chickens
7 pigs
Answer:
32
Step-by-step explanation:
Remark
Every triangle has 180 degrees as the total of its 3 angles.
Equation
x + 98 + 50 = 180
Solution
Combine the like terms on the left
x + 148 = 180
Subtract 148 fro both sides of the equation
x + 148- 148= 180 - 148
Combine
x = 32
x is 32 degrees in size
Answer:
The correct answer is 375 purple flowers.
Step-by-step explanation:
If all the F1 generation from true-breeding parents are purple than the genotype would be heterozygous i.e., Pp and Pp. Here P indicates the dominant allele which produces purple flower and p indicates the recessive allele of white flower.
So if we will cross the F 1 generation than the genotype would be PP, Pp, Pp, pp. That means 3 out of 4 offspring would be purple because three genotypes out of four have dominant purple allele(P).
So if out of 4 flower 3 is purple than according to calculation out of 500 flower 375 offspring would be purple(3/4*500= 375). Therefore the correct answer is 375 purple flowers should be produced.
