Set up and solve a system of equations to solve the problem.
NeTakaya

Answer:

The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch

Step-by-step explanation:

Let

x ----> the number of bags of hardwood mulch sold

y ----> the number of bags of pine bark mulch sold

we know that

A local boys club sold 136 bags of mulch and made a total of $400

so

x+y=136 ----> equation A

3.25x+2.75y=400 ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

Using a graphing tool

The solution is the point (52,84)

see the attached figure

therefore

The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. a. How many times larger is the are
PSYCHO15rus [73]

Answer:

The answer is below

Step-by-step explanation:

a) Triangle A is attached in the image below.

The base of triangle A is 3 units and its height is 3 units. The area of a triangle  is given as:

Area = (1/2) × base × height

Area of triangle A = (1/2) × base × height = (1/2) × 3 × 3 = 4.5 unit²

Area of the scaled copy = 72 unit²

Ratio of area = Area of the scaled copy / Area of triangle A = 72 unit² / 4.5 unit² = 16

Hence the scaled copy area is 16 times larger than that of triangle A.

b) For the scaled copy:

Area of the scaled copy = (1/2) × base × height = 72 unit²

base × height = 144

Since the base and height are equal

base² = 144

base = 12, also height = 12

Base of scaled copy = 12 = 4 × base of triangle A

Therefore the scale factor used is 4
