Find the missing side of the triangle. leave your answer in simplest radical form

KIM [24]

missing side is $x} = 10.15$ mi .

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

Here we have the following info from the figure: A right angled triangle with following dimensions

$Perpendicular = x$

$base = \sqrt{122}$

$Hypotenuse = 15$

By Pythagoras Theorem :

$Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $15^2 = x^2 + (\sqrt{122})^2$

⇒ $225 = x^2 + 122$

⇒ $x^2 = 225-122$

⇒ $x^2 = 103$

⇒ $(x^2)^\frac{1}{2} = (103)^\frac{1}{2}$

⇒ $x} = (103)^\frac{1}{2}$

⇒ $x} = 10.15$

Therefore, missing side is $x} = 10.15$ mi .

You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses. Your town requires 1/2 acre (one acre

Varvara68 [4.7K]

Answer:

You have 1.07 acres in this building lot and you can only build 2 houses.

Step-by-step explanation:

You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses.

We are given that 1 acre = 43,560 square feet.

In this building plot (260 foot by 180 foot), the area is:

260 * 180 = 46,800 square feet

Hence, the number of acres we have in this lot is:

$\frac{46800}{43560} = 1.07$

Since your town requires 1/2 acre to build a house, the number of houses that you can build on it will be:

$\frac{1.07}{\frac{1}{2} } = 1.07 * 2 = 2.14$

Since the number of houses can only be whole number, we approximate to nearest whole number ≅ 2 houses.

You have 1.07 acres in this building lot and you can only build 2 houses.

In 2018, Yolanda paid $4,526 in Social Security tax. If the Social Security tax rate was 6.2% to the maximum income of $128,400

lana [24]

Answer:

$73000

Step-by-step explanation:

Given: Social security tax paid by Yolanda is $4562.

6.2% tax to be paid on earning to the maximum income of $128400.

Lets assume Yolanda´s income be `x`.

Now, calculating the taxable income of Yolanda

∴ $62\% \times x= \$ 4526$

⇒ $\frac{62}{100} \times x= 4526$

Cross multiplying both side

⇒ x= $\frac{4526\times 100}{6.2}$

∴x= $73000

∴ Yolanda´s taxable income is $73000.
