Let's turn that into a linear system:
Set the equations equal to each other and solve:
We then plug in to get
:
The solution to the system is
.
Now, let's turn our attention to the statements.
The first one is
false: Emilia's rate is higher, and the two plans cost the same at 50 texts, after which point Hiroto's plan becomes
cheaper!
The second one is also
false: we already figured out that the lines intersect at
.
The third statement is also
false: as above, the lines intersect at
.
The fourth statement is
true: the lines intersect at
.
In conclusion, the fourth statement - "Both plans cost the same when 50 texts are sent" - is true.
Let’s say that the alleles are B’s. The alleles are different, so it would be Bb. Cross two of them to get BB, Bb, Bb, and bb. Blue eyes are homozygous recessive, or bb. There is a 1 in 4 chance of having a blue eyed child, or 25%.
Answer:
A. square root -4
Step-by-step explanation:
The answer is A because the square root of -4 is 2i which is an imaginary number.
-The square root of -4 is 2i (an imaginary number)
-The square root of 16 is 4
-The square root of 1 is 1
-The square root of 13 is ≈ 3.606
Answer:
44.5 yards
Step-by-step explanation:
Start with the formula of the circumference of a circle.
C = πd
Now all you have to do is plug in the numbers.
279.46 = (3.14)d
Divide both sides by 3.14
d = 89
But since you're finding the radius, you have to divide the diameter by 2.
89/2 = 44.5
