denominator = bottom part of the fraction

* means multiply

a.

you can only add the numerator when the denominator is the same

cant add the denominator

denominator has to be the same

1/5 = 4/20

4/20 + 7/20 = 11/20

b.

Step-by-step explanation:

a)1/5+ 7/20

1.find the CM of both denominators

2.multiply both the denominator and the numerator using the CM

=(1/5)×20 +(7/20)

=20/100 +35/100

since you multiply

3.Now add both numerators ( don't add the denominators)

=the answer is 55/100

What is the total amount for an investment of $1600 invested at 4.25% for 20 years and compounded continuously?
galina1969 [7]

Answer:

  $3743.43

Step-by-step explanation:

The amount is given by the formula ...

  A = Pe^(rt)

where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...

  A = $1600·e^(0.0425·20) = $1600·e^0.85

  ≈ $1600·2.33964685 ≈ $3743.43

The amount in the account will be $3743.43.

Hedya is 4 times as old as Hannah, and Hannah is 1.5 times as old as Hadassah. If the sum of their ages is 102, how old is Hadas
PtichkaEL [24]
Answer: Hadassah is 12.

Explanation:
x=Hedya
y=Hannah
z=Hadassah
x+y+z=102
x=4y
y=1.5z
z=?

4x1.5z=6z (also x or Hedya's age)
z+1.5z+6z=102
8.5z=102
z=12

Evaluate the function at x = –2. A. y = –4 B. y = 0 C. y = 2 D. y = 3
lys-0071 [83]
From the graph, identify the x=-2 point on x axis,
(is it 2 units to left of origin.)

now, imagine a vertical line through it.
This vertical line intersects the given line at which point?
The y co-ordinate of this point is your answer.

From the given graph,
the vertical line intersects at (-2,3)
so y= 3 it is :)
