Hello!

To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.

C = 2(36)π

C = 72π

Therefore, the circumference of the circle is 72π inches.

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles 3:4; but today the greedy h

Airida [17]

The weight of each pile yesterday will be 6 and 8 pounds.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is Given that Yesterday the ratio of seeds in these piles was 3:4.

Let 3x and 4x represent the seeds.

If the 2 pounds of seeds are added in the bigger pile, then

4x + 2

He also ate 1/4 pound from the smaller pile,

3x - 1/4

The quantities of seeds in those piles is in the ratio of 5:16.

So, 4x + 2 = 5x

3x - 1/4 = 16x

Solve;

So, 4x + 2 = 5x

2 = 5x - 4x

x = 2

The weight of each pie will be

3x = 6 pound

4x = 8 pound

Hence, The weight of each pile yesterday would be 6 and 8 pounds.

An airplane has a total of 414 packets of crackers, pretzels, and peanuts available for passengers.

zhenek [66]

There is no question in Part A, but i do what i can.

Part A.
We know that:

n - number of packets of crackers
p - number of packets of pretzels

p = 2n+9

s - number of packets of peanuts

s = 3p = 3(2n+9) = 6n+27

So:

$n+p+s=414\\\\n+(2n+9)+(6n+27)=414\\\\9n+36=414\quad|-36\\\\9n=378\quad|:9\\\\\boxed{n=42}\\\\\\
p=2n+9=2\cdot42+9=\boxed{93}\\\\s=6n+27=6\cdot42+27=\boxed{279}$

There are 42 packets of crackers, 93 packets of pretzels and 279 packets of peanuts.

Part B.

x - number of rows with exactly 2 passengers
y - number of rows with exactly 3 passengers

and:

$\boxed{\begin{cases}x+y=48\\2x+3y=132\end{cases}}\\\\\\
\begin{cases}x+y=48\quad|\cdot2\\2x+3y=132\end{cases}\\\\\\
\begin{cases}2x+2y=96\\2x+3y=132\end{cases}\\\\--------(-)\\\\2x-2x+2y-3y=96-132\\\\-y=-36\\\\\boxed{y=36}\\\\\\x+y=48\\\\x+36=48\\\\x=48-36\\\\\boxed{x=12}$

There are 12 rows with exactly 2 passengers and 36 rows with exactly 3 passengers.

Solve: -3x = 15 you can get the brainiest

kaheart [24]

If you times -3 by -5 the negatives cancel eachother and therefore you get 15.
