The inequality is
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days
Step-by-step explanation:
14 gallons-1.5 gallons=12.5 gallons
we know that
If the remaining fuel is greater than 1.5 gallons Diego's father can drive the car without the warning light coming on
so
Let
x ----> the number of days
----> inequality that represent the situation
Solve for x


The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

Which is not a correct way to rewrite this expression using the distributive
Effectus [21]

Given:

The expression is

(2x^2+4x-7)(x-2)

To find:

The expression which is not a correct way to rewrite the given expression.

Solution:

We have,

(2x^2+4x-7)(x-2)

Using distributive property, we get

=(2x^2)(x-2)+(4x)(x-2)+(-7)(x-2)

=(2x^2)(x)+(2x^2)(-2)+(4x)(x)+(4x)(-2)+(-7)(x)+(-7)(-2)

Using distributive property the given expression can rewritten as:

=(2x^2+4x-7)(x)+(2x^2+4x-7)(-2)

Only the expression in option A is not a correct way to rewrite the given expression because (2x^2+4x-7) is not distributed to (x-2) properly.

Therefore, the correct option is A.

Help please. only answer if you know :(
Harrizon [31]

Answer:

<em>x = 437.3 ft</em>

Step-by-step explanation:

<u>Right Triangles</u>

In right triangles, where one of its internal angles measures 90°, the trigonometric ratios are satisfied.

We have completed the figure below with the missing internal angle A that measures A = 90° - 29° = 61° because the lines marked with an arrow are parallel.

Given the internal angle A, we can relate the unknown side of length x with the known side length of 500 ft, the hypotenuse of the triangle. We use the sine ratio:

\displaystyle \sin 61^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}

\displaystyle \sin 61^\circ=\frac{x}{500}

Solving for x:

x = 500 \sin 61^\circ

Calculating:

x = 437.3 ft
