Step-by-step explanation:

area of equilateral ∆ =

( \sqrt{3}  \div 4) {a}^{2}

here a = 3

area of ∆ = 3.9 in^2

area of circle

\pi {r}^{2}

= 19.63 in^2

area of shared region = 19.63-3.9= 15.73 in^2

How many Children attended the classroom if there were 11 girls who made up 44% of the children?
WITCHER [35]

Answer:

25

Step-by-step explanation:

If 11 equals 44%, then x equals 100%.

x = \frac{100}{44} * 11

11 * 100 = 1100

1100/44 = 25

So, your answer is 25.

Allen is horrible at managing his money. For example, he
N76 [4]

Answer:

$80,000

Step-by-step explanation:

<u>Define the variables</u>:

Let x =  "fish-flavored" chicken company investment (in dollars)

Let y = spray-on vitamins company investment (in dollars)

If Allen invested a total of $100,000:

⇒ x + y = 100000

Given:

  • 3% profit on "fish-flavored" chicken investment
  • 1% profit on pray-on vitamins investment
  • Total profit = $2,600

⇒ 0.03x + 0.01y = 2600

Rewrite the first equation to make y the subject:

⇒ y = 100000 - x

Substitute into the second equation and solve for x:

⇒ 0.03x + 0.01(100000 - x) = 2600

⇒ 0.03x + 1000 - 0.01x = 2600

⇒ 0.02x + 1000 = 2600

⇒ 0.02x = 1600

⇒ x = 80000

Therefore, Allen invested $80,000 in the "fish-flavored" chicken company.

y=mx+b

m=-1

y-y=m(x-x¹)

y-1=-1(x-7)

y-1=-1x+7

+1 +1

y=-x+8
