In right triangle RST below, altitude SV is drawn to

Mathematics

Answer:

ST = 12.2

Step-by-step explanation:

See the attached diagram of the triangle.

Here, Δ RST, Δ RSV and Δ STV all are right triangles.

If we assume that, ST = x and SR = y, then

From Δ RSV and Δ STV we get,

SV² = RS² - RV² = ST² - VT²

⇒ y² - 4.2² = x² - 10.3²

⇒ x² - y² = 88.45 .......... (1)

Now, from Δ RST, we have

ST² + SR² = RT²

⇒ x² + y² = (10.3 + 4.2)² = 210.25 .............. (2)

Now, adding equations (1) and (2) we get,

2x² = 298.7

⇒ x² = 149.35

⇒ x = 12.2 (Rounded to the nearest tenth}

So, ST = 12.2 (Answer)

8/3 x 9/7 or 8/3 x 9/4<br> Which is greater? How do you know?
Vinvika [58]

Well, let's multiply them!

8/3 * 9/7 = 72/21

8/3 x 9/4 = 72/12.

We know the one with the smallest denominator is larger if the numerator is the same. So that means

72/12 is larger.

lawyer [7]

Answer:

$29,900

Step-by-step explanation:

The computation of the  balance of Work in Process as of April 30 is shown below:

= Opening balance of work in process + direct material cost + direct labor cost + factory overhead cost - goods finished

= $7,000 + $78,400 + $195,000 + $136,500 - $387,000

= $29,900

The  direct material cost + direct labor cost + factory overhead cost is known as manufacturing cost
