Work out the lengths of sides a and b. Give your answers to 1 decimal place.

torisob [31]

Step-by-step explanation:

${a}^{2} = {8}^{2} + {5}^{2} \\ {a }^{2} = 64 + 25 \\ {a}^{2} = 89 \\ a = \sqrt{89} = 9.4 \: cm$

${17}^{2} = {12}^{2} + {b}^{2} \\ {b}^{2} = {17}^{2} - {12}^{2} \\ {b}^{2} = 289 - 144 \\ {b}^{2} = 145 \\ b = 12 \: cm$

You have invested $2000 at 3.75% annual interest. How much money do you have after 20 years?

lbvjy [14]

Answer:

$3500

Step-by-step explanation:

Let's use PRT/100 to see what will be the total amount.

Total amount = Interest + Principle

Solution:

PRT/100 = Interest
=> 2000 x 3.75 x 20 years/100
=> 20 x 3.75 x 20 = Interest
=> 2 x 2 x 375 = Interest
=> 4 x 375 = Interest
=> 1500 = Interest
=> Total amount = 1500 + 2000
=> Total amount = $3500

Hence, after 20 years, the amount earned is $3500.

Tickets for the baseball games were $2.50 for general admission and 50 cents for kids. If there were six times as many general a

Makovka662 [10]

There was 3000 general admission tickets sold and 500 kid ticket sold.

How did I get this?

First, we need to see what information we have.
$2.50 = General admission tickets = (G)
$0.50 = kids tickets = (K)
There were 6x as many general admission tickets sold as kids. G = 6K

We need two equations:
G = 6K
$2.50G + $.50K = $7750
Since, G = 6K we can substitute that into the 2nd equation.

2.50(6K) + .50K = 7750
Distribute 2.50 into the parenthesis

15K + .50K = 7750
combine like terms

15.50K = 7750
Divide both sides by 15.50, the left side will cancel out.

K = 7750/15.50
K = 500 tickets
So, 500 kid tickets were sold.

Plug K into our first equation (G = 6k)

G = 6*500
G = 3000 tickets

So, 3000 general admission tickets were sold,

Let's check this:

$2.50(3000 tickets) = $7500 (cost of general admission tickets)
$.50(500 tickets) = $250 (cost of general admission tickets)
$7500 + $250 = $7750 (total cost of tickets)
