Answer:

A) x + 0.1 x > 3000.

Step-by-step explanation:

Given  :  John travels a certain number of x miles by airplane and then 0.1 miles as far by car. His total trip was more than 3000 miles.

To find : Which inequality models this situation.

Solution : We have given

John travels by air plane = x miles .

John travels by car = 0.1 x miles.

Total trip = 3000 miles.

Then  ,

x + 0.1 x > 3000.      ( His total trip was more than 3000 miles)

Therefore, A) x + 0.1 x > 3000.

Kipish [7]

Answer:

The measure of Arc EH is 123°.

Step-by-step explanation:

Consider the diagram below.

It is provided that ∠EDH ≅ ∠EDG.

This implies that: ∠EDH = ∠EDG

The arc measure is same as the measure of the central angle.

That is:

arc FE = ∠EDF = 57°

arc FG = ∠FDG = 66°

Compute the measure of angle ∠EDH as follows:

arc EH = ∠EDH

           =∠EDG

           = ∠EDF + ∠FDG

           = 57° + 66°

           = 123°

Thus, the measure of Arc EH is 123°.

Sum of positive roots of the equation (x2 - 12x + 35) (x2 + 10x + 24) = 504 is
Digiron [165]

Answer:

(3)11

Step-by-step explanation:

We are given that

(x^2-12x+35)(x^2+10x+24)=504

We have to find the sum of positive roots of the equation.

x^2(x^2+10x+24)-12x(x^2+10x+24)+35(x^2+10x+24)=504

x^4+10x^3+24x^2-12x^3-120x^2-288x+35x^2+350x+840=504

x^4-2x^3-61x^2+62x+840-504=0

x^4-2x^3-61x^2+62x+336=0

Factor of 336

2,3,4,6,8,7,

Let x=2

2^4-2^4-61(2^2)+62(2)+336\neq0

x=2 is not the root of equation

x=-2

(-2)^4-2(-2)^3-61(-2)^2+62(-2)+336=0

Hence x=-2 is the root of equation.

x+2 is a factor of equation.

x=3

3^4-2(3^3)-61(3^2)+62(3)+336=0

Therefore, x=3  is the root of equation.

(x+2)(x-3)(x^2-x-56)=0

(x+2)(x-3)(x^2-8x+7x-56)=0

(x+2)(x-3)(x(x-8)+7(x-8))=0

(x+2)(x-3)(x-8)(x+7)=0

x-8=0\implies x=8

x+7=0\implies x=-7

Positive roots are 3 and 8

Sum of positive roots=3+8=11

Option (3) is true.
