Adaline is designing a garden in the shape of a 45º-45º-90º triangle, with an area of 32 ft2. To the nearest foot, how much fenc
wel

Answer:

27 ft

Step-by-step explanation:

Given: A garden in the shape of a 45º-45º-90º triangle.

Area of triangle= 32 ft²

As given dimension of triangle, we understand that it is a right angle and triangle and since two angles are equal, therefore two sides of triangle are also equal.  

∴ Base and height will be equal.

Assuming base is also as "h"

Now, finding the length of base and height by using area of triangle formula.

Area of triangle=  \frac{1}{2} \times base\times height

⇒32= \frac{1}{2} \times h\times h  

Multiplying both side by 2

⇒64= h^{2}  

Square rooting both side, remember; √a²= a

⇒  \sqrt{64} = h

∴ h= 8 feet

Hence, both base and height of right angle triangle is 8 feet.

Next, finding total fencing required to enclose the garden.

Perimeter of garden is equal to the amount of fencing required by Adaline.

Therefore, finding the length of hypotenous of triangle too.

Using pythogorean theoram.

h^{2} = a^{2} +b^{2}, where a is the height and b is the base of triangle.

⇒ h^{2}= 8^{2}  +8^{2}

⇒ h^{2} = 128

Square rooting both side

⇒h= \sqrt{128}

∴ h= 11.3 feet

Perimeter of garden= base+height+hypotenous

⇒ Perimeter of garden= 8+8+11.3= 27.3\ feet \approx 27\ feet

Hence, 27 feet fencing is required to enclose the garden.

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the tota
denpristay [2]

Answer:

The total amount of money in Maria's account after 6 years is $8436

Step-by-step explanation:

Given;

principal amount , P = $5,700

interest rate, r = 8 % = 0.08

time of investment, t = 6 years

The interest on the invested money after 6 years is given by;

I = Prt

I = $5,700 x 0.08 x 6

I = $2736

Total amount in Maria's account is given by;

A = P + I

A = $5,700 + $2736

A = $8436

Therefore, the total amount of money in Maria's account after 6 years is $8436
