Answer:

Option A. $7\ basil$ and $11\ squash$

Step-by-step explanation:

Let

b-----> the number of packets of basil seed

s-----> the number of packets of squash seeds

we know that

$b+s=18$

$b=18-s$ -----> equation A

$1.5b+2.5s=38$ -----> equation B

substitute equation A in equation B and solve for s

$1.5(18-s)+2.5s=38$

$27-1.5s+2.5s=38$

$s=38-27$

$s=11$

Find the value of b

$b=18-11=7$

therefore

$7\ basil$ and $11\ squash$

Estimate the size of a crowd walking in a charity fundraising march that occupies a rectangular space with dimensions of 10 feet

jolli1 [7]

Answer:

4000 is size of a crowd walking in a charity fundraising March.

Step-by-step explanation:

Given:

Dimensions of rectangular space 10 feet by 12000 feet

So we can say that,

Length = 1200 ft

Width = 10 ft

Now we will calculate the area of rectangular space which is given by

Hence Area will be = $length\times width= 10\ ft \times 1200 \ ft= 12000 \ ft^2$

Now we know that 40 people occupy a rectangle measuring 10 feet by 12 feet.

Length = 12 ft

Width = 10 ft

Area = $length\times width= 10\ ft \times 12 \ ft= 120 \ ft^2$

It says that 40 people are occupied in 120 $ft^2$

So how many people will be there in 12000 $ft^2$

By using unitary method we get,

Number of people = $\frac{40\times 12000 \ ft^2}{120 \ ft^2} = 4000 \ peoples$

Size of a crowd walking in a charity fundraising March is 4000.
