Solution:

<u>Note that:</u>

Probability that the tile will be green: Green tiles/Total tiles

Green tiles/Total tiles
=> 6/6 + 3 + 3
=> 6/12 = 1/2 = 50/100 = 0.5

The probability (In decimal) of obtaining a green tile is 0.5.

A combined total of 39000 is invested in two bonds that pay 5% and 6.5% simple interest. The annual interest is 235500 how much

dolphi86 [110]

Answer:

$12000 at 5%

$27000 at 6.5%.

Step-by-step explanation:

Let x represent amount invested at 5% and y represent amount invested at 6.5%.

We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:

$x+y=39000...(1)$

We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:

$0.05x+0.065y=2355...(2)$

Upon substituting equation (1) in equation (2), we will get:

$0.05x+0.065(39000-x)=2355$

$0.05x+2535-0.065x=2355$

$-0.015x+2535=2355$

$-0.015x=2355-2535$

$-0.015x=-180$

$\frac{-0.015x}{-0.015}=\frac{-180}{-0.015}$

$x=12000$

Therefore, an amount of $12,000 is invested at 5%.

Upon substituting $x=12000$ in equation (1), we will get:

$12000+y=39000$

$y=39000-12000$

$y=27000$

Therefore, an amount of $27,000 is invested at 6.5%.

HELP PLEASE 3. Simplify the expression (5 points)<br> [(7 + 3) • 5 - 4] = 2 + 2

krok68 [10]

Answer: 46 or 46=4

Step-by-step explanation:

Do what's in the Parenthesis first so 7+2=10 which now give you the equation

[10x 5-4]=2+2

Now we Multiply so we do 10x5 which is 50 so that now gives us the equation[50-4]=2+2

Now we add the 2+2 which is 4 giving us the equation [50-4]=4

Now we subtract 50-4 giving 46

46=4

A train from Portland, Oregon, to Los Angeles, California, travels at an average speed of 60 miles per hour and covers a distanc

seropon [69]

Answer:

The train need to leave Portland at 03:27 am

Step-by-step explanation:

step 1

Find out how long it takes the train to travel from Portland, Oregon, to Los Angeles, California

Remember that

The speed is equal to divide the distance by the time

so

The time is equal to divide the distance by the speed

Let

s ---> the speed in miles per hour

d ---> the distance in miles

t ---> the time in hours

$t=\frac{d}{s}$

we have

$d=963\ mi$

$s=60\ mi/h$

substitute

$t=\frac{963}{60}=16.05\ hours$

step 2

Adds 30 minutes (time it takes to get from the train station to her aunt's house)

Remember that

$30\ minutes=0.50\ hours$

$16.05+0.50=16.55\ hours$

Convert to minutes

$16.55\ h=16.55(60)\ min=993\ min$

step 3

Remember that

$8 p.m=20:00\ hrs$

Convert to minutes

$20(60)=1,200\ min$

Subtract 993 minutes from 1,200 minutes

$1,200-993=207\ min$

Convert to hours+minutes

$207\ min=207/60=3.45\ hours$

$0.45\ h=0.45(60)=27\ min$

so

$3\ h+27\ min$

$00:00 + 03:27=03:27\ am$

therefore

The train need to leave Portland at 03:27 am
