Answer:

<em><u>It will cost $2.52 shipping fee to ship an item that costs $56</u></em>

Step-by-step explanation:

You can get the answer by multiplying 4.5% by $56.

Before you multiply , you need to convert the percent to a decimal which would 0.045.

C = 0.045(56) = 2.52

A light bulb filament is one-hundredth of an inch thick, with an allowable error of 2 percent. What is the least allowable thick
Andreyy89

Answer:

0.00998 Inches

Step-by-step explanation:

Thickness of the light bulb filament = 0.01 Inch

Allowable error = 2%.

2% of 0.01 = 0.02 X 0.01 =0.0002 Inch

Therefore, the allowable thickness of the bulb filament

=0.01 \pm 0.0002 $ Inches

We can then calculate the least allowable thickness of the filament as:

=0.01 - 0.0002 \\=0.00998$ Inches

The least allowable thickness of the filament is 0.00998 Inches.

If line n bisects segment CE, find the positive value of x.<br><br> A.6<br> B.10<br> C.15<br> D.9
givi [52]

9514 1404 393

Answer:

  D.  9

Step-by-step explanation:

The segment lengths are equal, so ...

  x^2 = 90-x

  x^2 +x -90 = 0 . . . . . . add x-90 to put in standard form

  (x +10)(x -9) = 0 . . . . . factor

The solutions are the values of x that make the factors zero: -10, 9.

The positive value of x is 9.

Write the equation of the line that is perpendicular to y=2x-7 and passes through the point (6, 5)
Pani-rosa [81]

Answer:

B

Step-by-step explanation:

we are given a equation of a line

we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points

in order to do so

recall that,

\displaystyle m_{ \text{perpendicular}} =   - \frac{1}{m}

we got from our given equation that m=2

because equation of a line is y=mx+b

thus

\displaystyle m_{ \text{perpendicular}} =   - \frac{1}{2}

remember that, when we want to figure out perpendicular line or parallel line we should the formula given by

\displaystyle y -  y_{1} = m(x -  x_{1})

since we got our perpendicular m is -½, x_1=6 and y_1=5, substitute

\displaystyle y -  5 =   - \frac{1}{2} (x -  6)

to get the perpendicular equation you should simplify the above equation to y=mx+b form

distribute -½:

\displaystyle y -  5 =   - \frac{1}{2} x  + 3

add 5 to both sides:

\displaystyle y  =   - \frac{1}{2} x  + 8

hence,

our answer choice is B

A hot air balloon holds 1,592 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic
yuradex [85]

Answer: 285.2 kg

Step-by-step explanation:

Given

The volume of helium in the balloon is V=1592\ m^3

The density of the helium is \rho =0.1785\ kg/m^3

Mass of the helium gas is given by the product of density and volume

\Rightarrow M=\rho \cdot V\\\Rightarrow M=0.1785\times 1592\\\Rightarrow M=285.2\ kg

Thus, the mass of gas is 285.2 kg
