Answer:

Step-by-step explanation:

pythagoras theorem

a^2+b^2=c^2

12^2+x^2=13^2

144+x^=169

x^2=169-144

x= $\sqrt{25$

x=5 km

<h3>Answer:</h3>

The missing side of the triangle is 5 km.

<h3>Step-by-step explanation:</h3>

Here we have

Perpendicular = 12 km

missing side = base = x

hypotenuse = 13 km

And since , we have given right triangle in a question . So we can use Pythagoras theorem

Pythagoras theorem

( Perpendicular ) ² + ( Base ) ² = ( hypotenuse ) ²

substitute the value

( 12 km ) ² + ( x ) ² = ( 13 km ) ²

Multiplying the values

144 km ² + x² = 169 km²

now Solve it

x ² = 169 km² - 144 km²

x ² = 25 km ²

x = √25 km²

x = 5 km.

Hence , missing Side of triangle is 5 km.

Solution Given number 1 : Peaches => 0.5 pound = meaning, ½ pound is available, And 1 pound of it costs 0.80 dollars. Let’s solve: => 0.80 dollars * 0.5 => 0.40 dollars – the price of the peaches. Given number 2 : Oranges => 0.7 pounds of oranges, meaning less than 1 pound. And 1 pound costs 0.90 dollars Let’s solve to get the anwer => 0.7 * .90 => 0.63 dollars – the costs of 0.7 pounds of oranges,

Amy opened a savings account with $1750 she received for graduation. The account pays 4.3% simple interest. What is the balance

Cerrena [4.2K]

Given:

The principal amount that Amy opened her savings account with is $1750.
The rate of simple interest compounded annually is 4.3%.
The time period for which we calculate the new balance is 6 months.

To Find:

The balance after 6 months.

Answer:

The balance after 6 months will be $1787.625

Step-by-step explanation:

The principal amount that Amy opened her savings account with is $1750. We can denote this by P.

The rate of simple interest compounded annually is 4.3% which we may denote by R.

The time period for which we calculate the new balance is 6 months which can be written as 0.5 years (since the rate of interest is compounded annually, we must consider the time period in terms of years).

The amount of money accrued from the interest can be calculated by the formula

$\frac{PRT}{100}$

Putting in the values given in the question, we have

$\frac{(1750)(4.3)(0.5)}{100} = 37.625$

The amount in the bank account will be the principal amount plus the amount of interest accrued that we have calculated above.

Thus, the balance after 6 months will be 1750 + 37.625 = $1787.625.
