Answer:

3 bags are needed to cover this flower bed

Step-by-step explanation:

Use conversion:

1 yard = 3 feet

Area of a triangle(A) is given by:

A = \frac{1}{2}bh

where,

b is the base and h is the height of the triangle.

As per the statement:

From the given diagram:

Base(b) = 3 yards = 9 feet

Height(h) = 2 yard = 6 feet

then;

A = \frac{1}{2} \cdot 6 \cdot 9 = 3 \cdot 9 = 27 square feet.

Since, it is given that if one bag of topsoil covers 10 square feet

⇒10 square feet =  1 bag

then\;

in 27 square feet = \frac{27}{10} = 2.7 \approx 3 bag

Therefore, 3 bags are needed to cover this flower bed

bixtya [17]

Answer:

b+5\geq 12

Step-by-step explanation:

Given:

Number of bushes planted = 5

Minimum number of bushes to be planted = 12

Let the number of bushes planted after planting 5 bushes be b.

Since, Tamara has already planted 5 bushes, total number of bushes planted is given as:

b+5

Now, as per question, total number of bushes should be 12 or greater than 12.

Therefore, b+5\geq 12.
