Marsha Waite borrows $7,000 and agrees to pay it back in 2 years if the simple interest rate is 15%

I am Lyosha [343]

Answer:

Marsha must pay in 2 years $\$9,100$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the amount of money to pay

P is amount of money borrowed

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=2\ years\\ P=\$7,000\\ A=?\\r=15\%=15/100=0.15$

substitute in the formula above

$A=7,000(1+0.15*2)$

$A=7,000(1+0.30)$

$A=7,000(1.30)$

$A=\$9,100$

therefore

Marsha must pay in 2 years $\$9,100$

In triangle DEF, DK is the angle bisector of angle EDF. If EK=2, FK=5, and DF=10, what is the length of DE?

fiasKO [112]

Answer:

4 units

Step-by-step explanation:

In triangle DEF, DK is the angle bisector of angle EDF.

<u>Angle bisector theorem</u> states that if a ray bisects an angle of a triangle, then it divides the opposite side into segments that are proportional to the other two sides.

Hence,

$\dfrac{DE}{DF}=\dfrac{EK}{KF}$

Thus,

$\dfrac{DE}{10}=\dfrac{2}{5}\\ \\5DE=2\cdot 10\\ \\5DE=20\\ \\DE=4$
