Answer:

9 1/8

Step-by-step explanation:

1. first take away the fraction part and take the whole numbers off of the numbers and add them!

1 + 3 + 5 = 9

2. now take that aside and keep that for later... now lets focus on the

1/2, 3/4, and the 1/8 these are the STARS you will be focusing on!

3. now, find the common denominator in these fractions!!!

how? here is how!

1. lets list these fractions:

1/2, 3/4, and 1/8

the common demoninator is <u><em>8 </em></u> because 1. its one of the highest in this set and 2. if you multiply 1/2 and 3/4 n the numerator and the demoentator by 4 they can create a 8 denminator and then you can add them!

4. Next, I wont be explaning you just watch!

3 x2 6

_ = _

4 x2 8 (to get to 8 from 4 you multiply by 2! so you do the same for the upper one!!!)

1 x4 4

_ = _

2 x4 8

you dont do anything to 1/8 because its already part of the eights family! :D

5. I know, it took us a LONG way here but here it is! the final! now, time to add them!

4/8, 6/8 and 1/8

6. lastly...

1 1/8 + 9 = 9 1/8

Hope this helpes! sorry this was so long!!! :D

A and B are two points on square ABCD with coordinates A(1,3) and B(5,3). What are the lengths of the diagonals AC and BD? Round

lilavasa [31]

Answer:

$AC = BD = 5.7$

Step-by-step explanation:

Given

$A = (1,3)$

$B = (5,3)$

Required

The length of the diagonals

First, calculate the length of AB using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

So, we have:

$AB = \sqrt{(1 - 5)^2 + (3 - 3)^2}$

$AB = \sqrt{(-4)^2 + 0^2}$

$AB = \sqrt{16}$

$AB = 4$

The diagonal of a square is calculated using:

$Diagonal = x\sqrt{2$

Where x is the length of each side.

So:

$AC = BD = AB\sqrt{2}$

$AC = BD = 4\sqrt{2}$

$AC = BD = 5.7$ -- approximated

Pam open a bank account with $200 deposit that account had a simple interest rate of 4.6% her most recent bank statement shows a

Marina86 [1]

Answer:

$t=14\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$200\\ A=\$328.80\\r=0.046$

substitute in the formula above and solve for t

$328.80=200(1+0.046t)$

$(328.80/200)=(1+0.046t)$

$t=[(328.80/200)-1]/0.046$

$t=14\ years$
