Answer: He will need to use 25.2 pounds on his lawn.

Step-by-step explanation: If Jean-Patrick found a bag that contains 36 pounds worth of fertilizer and it can cover 10000 square feet of earth, then he needs to find out how many square feet of earth can be covered by just one pound of fertilizer.

After that, he can multiply that portion by 7000 feet to determine how many pounds in total he would need for his lawn.

To cover one square foot of earth, he would need;

1 ft = 36/10000

1 ft = 0.0036

That means for each square foot of earth, he would need 0.0036 pound of fertilizer. In order to fertilize 7000 square feet of earth, he would need the following

Total = 0.0036 x 7000

Total = 25.2

Jean-Patrick would need 25.2 pounds of fertilizer for his lawn

Answer:

He needs to use 25.2 pounds to fertilize his lawn.

Step-by-step explanation:

In order to solve this problem we can use a rule of three in such a way that the content of the bag (36 pounds) can cover 10,000 ft² in the same proportion as "x" pounds can cover 7,000 ft², where "x" is the amount of fertilizer he needs to use.

36 pounds -> 10,000 ft²

x pounds -> 7,000 ft²

36/x = 10000/7000

10000*x = 36*7000

x = 36*7000/10000

x = 25.2 pounds

He needs to use 25.2 pounds to fertilize his lawn.

No unit fractions are shown. (Sometimes editing is required when you copy and paste your question text.)

Selections B and D have 1 as their first digit. We suspect those are supposed to be the unit fractions 1/8 and 1/3, respectively.

Answer:

$\frac{180}{147}$

Step-by-step explanation:

Simplify $(\frac{3}{-7} - \frac{11}{21} )$

$=> \frac{(-3 \times 3) - 11}{21}$

$=> \frac{-9 - 11}{21}$

$=> \frac{-20}{21}$

Find the additive inverse of $\frac{-20}{21}$ by using its property - <em>"Sum of a number & its additive inverse is always zero". </em>Assume that 'x' is an additive inverse of $\frac{-20}{21}$ .
