Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after

Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

$i=Prt$

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

$i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61$

The interest earned is $395.61

Determine whether the ordered pair (1, 1) is a solution of the inequality. y ≤ -3x+1

solong [7]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{(1, 1) is NOT a solution of the inequality}$

-------------------------------------------------------------------------------------------------------------

Given: $y \le-3x + 1$

Find: $\textsf{Determine if (1, 1) is a solution of the inequality}$

Solution: In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.

Plug in the values

$y \le-3x + 1$

$1 \le-3(1) + 1$

Simplify

$1 \le-3 + 1$

$1 \le-2$

As we can see the expression states that 1 is less than or equal to -2 which is false therefore (1, 1) is NOT a solution of the inequality.

For two line segments to be parallel, their slopes must be equal.

Therefore slope of AB must be equal to slope of CD

which is, option 3
 (y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)

Question o

taurus [48]

The equation -21t - 4 = 10 - 2t has only one solution

Solution:

Given, equation is – 21t – 4 = 10 – 2t

We have to find how many solutions does the above given equation have

Now, let us solve the given equation to find the number of solutions it has.

Then, - 21t – 4 = 10 – 2t

Taking like terms to one side of the equation we get,

- 21t + 2t = 10 + 4

$\begin{array}{l}{-19 t=14} \\\\ {19 t=-14} \\\\ {t=-\frac{14}{19}}\end{array}$

here we can see only one value of t.

Hence, the given equation has only one solution.
