A blueprint for a house has a scale of 1:5 feet. The living room has a length of 2.5 inches and a width of 3 inches. What is the
stiks02 [169]

Answer:

Step-by-step explanation:

Set this up as a proportion, with inches on the top and feet on the bottom for our scale.  We will find the actual length first, then we'll find the width.

\frac{in}{ft}:\frac{1}{5}=\frac{2.5}{x}

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet.  Now for the width:

\frac{in}{ft}:\frac{1}{5}=\frac{3}{x}

Cross multiply to get that the actual width is 5(3) = 15 feet.

If you want the area of the room, multiply the length times the width to get

A = 15(12.5)

A = 187.5 feet squared

HELPPPPP Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropria
Romashka-Z-Leto [24]

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:

c² = a² + b² - 2abcosC

16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC

C = 91.2°

Also:

a² = b² + c² - 2bccosA

8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA

A = 31.4°

A + B + C = 180° (angles in a triangle)

31.4 + B + 91.2 = 180

B = 57.4°

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

your boss estimates it take 42 person - hours to rearrange the floor plan for the produce department at a local grocery store. Y
Aleksandr-060686 [28]
It is important to read the question very carefully. The trick lies in the way the question is written. Once it is understood, then the problem is easy.
Number of persons required to rearrange the floor plans in 1 hour = 42
Number of persons required to rearrange the floor plans in 9 hours = 42 * 9
                                                                                                             = 378 hours
So it will take 378 hours by 9 persons to rearrange the floor. I hope this is the answer you were looking for and the procedure is also clear to you. Once you understand the procedure, you can attempt such problems on your own in future.
