The error is in step 4. The sign was not changed after dividing both sides by -10. Thus, the answer to the inequality should be: -27/10 ≥ x.

<h3>How Negative Number Changes Inequality Sign?</h3>

When we divide or multiply two sides of an inequality by a negative number, the inequality sign is changed to the opposite, i.e. from < to > or from > to <.

In step 4, the sign was not changed after dividing both sides by -10.

The answer should be, -27/10 ≥ x.

Given circle E with diameter CD and radius EA. AB is tangent to Eat A.

faust18 [17]

The hypotenuse is equal to the square of the other two sides. The length of AC from the diagram is 21.9feet

<h3>Application of pythagoras theorem</h3>

The theorem states that the square of the hypotenuse is equal to the square of the other two sides

Given the following

Hypotenuse = 26 feet = CD
Base side = AD = 14ft

Required

Length AC

Use the theorem

26^2 = 14^2 + AC^2

AC^2 = 676 - 196
AC^2 = 480
AC = 21.9feet

Hence the length of AC from the diagram is 21.9feet

Dropping less than two inches per mile after emerging from the mountains, a river drains into the ocean. One days discharge at i

Ulleksa [173]

Answer:

8000 gallons/household per month

Step-by-step explanation:

Given that the discharge of 4.8 trillion gallons could supply country A households in 6 months, find for a single month.

Divide the discharge (4.8 trillion gallons) by 6

4.8/6 =0.8 trillion gallons supplied to country,s households in 1 month

To find usage per household, divide the supply per month by the number of households

=0.8 × 1000,000,000,000 gallons/100,000,000 households

=0.8×10,000 gallons/household

=8000 gallons/household per month
