It is wrong because the equation is missing parentheses around the sum

When it says "the quantity of..." it always means parentheses. The correct equation is 2(3x+4)

Which is the standard form for this number? (4 x 1 100 ) + (8 x 1 1,000 ) + ( 3 x 1 100,000 ) ?

kondaur [170]

Answer:

Option B $0.04803$

Step-by-step explanation:

we have

$(4*\frac{1}{100})+(8*\frac{1}{1,000})+(3*\frac{1}{100,000})\\ \\ =(\frac{4}{100})+(\frac{8}{1,000})+(\frac{3}{100,000}) \\ \\ =0.04+0.008+0.00003\\ \\=0.04803$

Using a 10' long piece of strut as a straightedge, you are trying to determine the outside diameter of a grain storage silo. You

Vesna [10]

The radius of the silo is the distance from its center to the outside wall

The radius of the silo is 7 3/8" or 7 3/8 inches

<h3>How to determine the radius?</h3>

From the question, we have the following parameters:

Length of strut = 10'
Outside diameter of silo = 14 3/4"

The radius is then calculated as:

Radius = 0.5 * Diameter

This gives

Radius = 0.5 * 14 3/4"

Evaluate the product

Radius = 7 3/8"

Hence, the radius of the silo is 7 3/8" or 7 3/8 inches
