What is the value of x
Misha Larkins [42]
ANSWER:

x = 55°

The value of 'x' is equivalent to 55°.

STEP-BY-STEP EXPLANATION:

The rhombus in the rectangle is a regular rhombus. It has two pairs of parralell sides.

Therefore, we can use co-interior angles on parallel lines to solve this problem. Co-interior angles are two angles on parallel lines which form a 'C' shape and add up to 180°.

THEREFORE:

( 2x + 20 )° + ( 50 )° = 180°

2x = 180 - 20 - 50

2x = 110

x = 110 / 2

x = 55°

Determine the first four numbers of N if N is<br><img src="https://tex.z-dn.net/?f=N%20%3D%20%20%5Csqrt%7B122436486072...2400%7D
Anestetic [448]

Answer:

  • 1106 . . . or
  • 3499

  see below for explanation

Step-by-step explanation:

The first four digits of the root depend on whether the exponent in scientific notation is even or odd.

If it is <em>even</em>, then the mantissa of the root is ...

N \approx\sqrt{1.2243648607}\approx 1.106\dots

If it is <em>odd</em>, then the mantissa of the root is ...

N \approx\sqrt{12.243648607}\approx 3.499\dots

The original price of a car is entered into spreadsheet cell A1 and the annual depreciation amount in cell B1.
Reil [10]

Answer:

A1 / B1 ;

(D1 - A1) / B1 ;

(A1 - E1*A1) / B1

Step-by-step explanation:

A1 = original price of car

B1 = annual Depreciation amount

Number of years it will take for the car to depreciate totally :

Using the straight line Depreciation relation :

y = mx + c

c = intercept = initial or original value of car

m = annual Depreciation amount

x = number of years

y = value after x years

For total Depreciation, final value, y = 0

0 = mx + c

mx = - c

x = - c / m

Hence, x = A1 / B1

B.)

D1 = car value

Length it will take for car to depreciate to value in D1 :

y = mx + c

y = D1; m = B1 ; c = A1

D1 = B1x + A1

B1x = D1 - A1

x = (D1 - A1) / B1

C.)

E1 = decrease percentage

Time it takes for car to decrease by percentage in E1

y = E1 * A1

E1 * A1 = B1x + A1

(A1 - E1*A1) = B1x

x = (A1 - E1*A1) / B1
