Rosa deposits $5000 in a savings account that gets compounded interest annually at a rate of 8%. If she leaves her money in the account for 2 years, how much will she have at the end of that time?
Answer:
$5318
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 2650 × 0.04 × 3 = 318
I = $ 318.00
The simple interest accumulated
on a principal of $ 2,650.00
at a rate of 4% per year
for 3 years is $ 318.00.

Answer:
1. Given
2. Corresponding Angles Theorem
3. ∠NPO ≅ ∠MQN (or something similar)
4. AA Similarity Theorem
Step-by-step explanation:
1. Line MQ || Line OP is the given statement.
2. ∠QNM on the left triangle corresponds to ∠PNO on the second triangle.
3. These two angles are cut by a transversal (Line MP), and thus are congruent.
4. ∠MQN and ∠NMQ are congruent to ∠NOP and ∠NPO respectively, so the triangles are similar.

The vertices of parallelogram DEFG are E(-1,4) F(5,6) and G (8,0). Find the coordinates of D
Answer:
The coordinates of D are (2,-2)
Step-by-step explanation:
The coordinates of point D are (2,-2)
The coordinates of the parallelogram are given as:
E(-1,4), F(5,6) and G (8,0)
For the coordinates to represent a parallelogram, the following must be true
[tex]x_D - x_E = x_G - x_F[/tex]
[tex]y_D - y_E = y_G - y_F[/tex]
So, the equations become
[tex]x_D -(-1) =8-5[/tex] and
[tex]y_D -4 =0-6[/tex]
Solve for x and y in the above equations
[tex]x_D -(-1) =8-5[/tex]
[tex]x_D +1 = 3[/tex]
[tex]x_D = 3-1[/tex]
[tex]x_D = 2[/tex]
[tex]y_D -4 =0-6[/tex]
[tex]y_D - 4 = -6[/tex]
[tex]y_D = 4-6[/tex]
[tex]y_D =-2[/tex]
Hence, the coordinates of point D are (2,-2)

The expression 4(1.20)t represents the population of rabbits each year. If x% represents the growth rate for the population of the rabbits each year, what is the value of x?
The growth rate for the population of the rabbits each year is 20%
What is an exponential equation?An exponential equation is an expression that shows how numbers and variables using mathematical operators.
Exponential exponential is in the form:
y = abˣ
Where a is the initial value and b is the multiplication factor.
Given the expression [tex]4(1.20)^t[/tex] represents the population of rabbits each year. If x% represents the growth rate, hence:
b = 1.20
growth rate = 1.20 - 1 = 0.20
growth rate = 20%
The growth rate is 20%

well this should be simple
if a small car averages 29 miles MORE, and it averages 44, the. just take 44 - 29.. which is 15.
Well if he has to go 240 miles, and he’s drove 135, just take 240 - 135 = y
240 - 135 = 105
y = 105
