Answer:

x = 11/2

Step-by-step explanation:

Combine like terms to get -4x + 15 = -7

Subtract 15 from both sides to get -4x = -22

Divide both sides by 4 to get x = 11/2

Donatello Co. has identified an activity cost pool to which it has allocated estimated overhead of $9,600,000. It has determined
ahrayia [7]

Answer:

option (a) Widgets $2,400,000, Gadgets $1,800,000, Targets $5,400,000

Step-by-step explanation:

Data provided in the question:

Allocated estimated overhead = $9,600,000

Expected use of cost drivers for the activity = 800,000 inspections.

Inspections required by Widgets = 200,000

Inspections required by Gadgets = 150,000

Inspections required by Targets = 450,000

Therefore,

Total overhead per activity = \frac{\textup{estimated overhead}}{\textup{Total activity}}

= \frac{\textup{9,600,000}}{\textup{800,000 }}

= $12 per activity

Thus,

Overhead allocated to Widgets = 200,000 × 12 = $2,400,000

Overhead allocated to Gadgets = 150,000 × 12 = $1,800,000

Overhead allocated to Target = 450,000 × 12 = $5,400,000

Hence, The correct answer is option (a)

How do you find the complex and real roots for x^4-3x^2+2=0
pogonyaev
X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0

so either x^2 - 2 = 0  or x^2 - 1 = 0

so x^2 = 2 or x^2 = 1

so x = sqrt 2 , - sqrt2, 1 , -1   Answer

all the roots are real

An architectural firm wants to replicate a nearby estate with some changes. The new estate will be larger than the original by a
Oduvanchick [21]

Answer:

Option B.

Step-by-step explanation:

It is given that the new estate will be larger than the original by a scale factor of 1:10.

A section of the roof in the original estate is constructed using 45-45-90 triangles. The hypotenuse of the triangle is 10 meters long.

Two angles are equal and one angle is a right angle, it means it is an isosceles right-angled triangle.

Let x be the length of the legs of the triangle for the larger estate.

The hypotenuse of larger estate = 10 × 10 = 100

Using Pythagoras triangle,

perpendicular^2+base^2=hypotenuse^2

x^2+x^2=(100)^2

2x^2=10000

Divide both sides by 2.

x^2=5000

Taking square root on both sides.

x=\sqrt{5000}

x=70.71\text{ meters}

Hence, the correct option is B.
