(4x^4-x2-x)+(x^4+x^3+x^2+x-1)
=4x^4 - x2 - x + x^4 + x^3 + x^2 + x- 1
=5x^4 + x^3 - 1

(x^2 and x are canceled out)...
x^2 - x^2 = 0
x -x =0

A worker is exposed to 98 dB for five hours and 82 dB for three hours, giving an eight-hour working day. On average, what noise

julia-pushkina [17]

Answer:

92 dB

Step-by-step explanation:

Use the mean formula, mean = sum of elements / number of elements.

Since it is a 8 hour work day, there are 8 elements.

mean = sum of elements / number of elements

mean = (98 + 98 + 98 + 98 + 98 + 82 + 82 + 82) / 8

mean = 736 / 8

mean = 92

So, the average noise level is 92 dB

In the Holiday Shop the manager wants 20% of the total inventory in the stockroom and the rest displayed on the floor. After mee

Lilit [14]

Answer:

Total inventory: $175,000

Inventory in the stockroom: $35,000.

Inventory on the selling floor: $140,000.

Step-by-step explanation:

Let x be the the total inventory.

We have been given that in the Holiday Shop the manager wants 20% of the total inventory in the stockroom. You placed $35,000 of inventory in the stockroom.

We can set an equation such that 20% of x equals $35,000.

$\frac{20}{100}\cdot x=\$35,000$

$0.20x=\$35,000$

$\frac{0.20x}{0.20}=\frac{\$35,000}{0.20}$

$x=\$175,000$

Since $35,000 of inventory in the stockroom, so we will subtract $35,000 from $175,000.

$\text{Amount of the inventory on the selling floor}=\$140,000$

Therefore, $140,000 of the inventory on the selling floor.

Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC . What is the leng

Thepotemich [5.8K]

Answer:

Length of side of rhombus is $x=\frac{ab}{a+b}$

Step-by-step explanation:

Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.

It is also given that AB=a and AC=b

Let side of rhombus is x.

In ΔCEF and ΔCBA

∠CEF=∠CBA (∵Corresponding angles)

∠CFE=∠CAB (∵Corresponding angles)

By AA similarity rule, ΔCEF~ΔCBA

∴ their sides are in proportion

$\frac{EF}{AB}=\frac{CF}{AC}$
