Find the balance of the account using the simple interest formula of I=Prt
prohojiy [21]

Given:

Principal = $1400

Simple rate of interest = 1.25%

Time = 6 month

To find:

The balance of the account after simple interest.

Solution:

The formula for simple interest is

I=\dfrac{P\times r\times t}{100}

Where, P is principal, r is the rate of interest in % and t is time in years.

Time = 6 months

        = \dfrac{6}{12} year

        = 0.5 year

Putting 1400, r=1.25, t=0.5 years.

I=\dfrac{1400\times 1.25\times 0.5}{100}

I=\dfrac{875}{100}

I=8.75

Now, the amount is

A=P+I

A=1400+8.75

A=1408.75

Therefore, the balance of the account after the simple interest is $1408.75.

What are the values of x and y?
adoni [48]

Answer:

Step-by-step explanation:

hello :

use pytagor-rule :

triangle ABC : (x+15)² =17²+y²....(*)

triangle BDC : y² = x²+8²....(**)

by (**) put the value of y² in (*) :

(x+15)² = 17²+x²+8²

x²+30x+15² = 17²+x²+18²

30x +225 = 289+64

30x = 128

x= 128/30

x= 64/15

put this value in (**) calculate y²  ......continu

What are the coordinates of the reflection of a,b over the y axis
Nady [450]
When you reflect over the y-axis, you negate the x coordinate and maintain the same y coordinate.

so (a,b) reflected over the y-axis would be (-a,b).
