PLZ ANSWER PIC INCLUDED​
Alchen [17]

Answer:

28 feet

Step-by-step explanation:

We know that the perimeter of a square is 2l + 2w, where l is the length and w is the width.

We also know that the perimeter of a triangle is all of its sides added up.

Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.

Basically:

(3x - 3) + (3x - 3) + (x - 3) + (x - 3) = (2x - 1) + (2x - 1) + (2x)

We can combine like terms to get a <em>less scary</em><em>  </em>equation.

8x - 12 = 6x - 2

Our goal is to now isolate x so we can find it's value.

Add 2 to both sides:

8x - 10 = 6x

Subtract 6x from both sides:

2x - 10 = 0

Add 10 to both sides:

2x = 10

Divide both sides by 2:

x = 5

Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.

Let's do it on the triangle.

6x-2 (remember, this is our simplified version of the triangle)

6(5) - 2\\\\30 - 2\\\\28

Hope this helped!

Paha777 [63]

Answer:

y\le\dfrac{1}{2}x+2

Step-by-step explanation:

On a coordinate plane, a solid straight line has a positive slope and goes through (negative 4, 0) and (0, 2). This line has the equation

y-0=\dfrac{2-0}{0-(-4)}(x-(-4))\\ \\y=\dfrac{1}{2}(x+4)\\ \\y=\dfrac{1}{2}x+2

The origin belongs to the shaded region, so its coordinates must satisfy the inequality. Since

\dfrac{1}{2}\cdot 0+2=2\ge 0,

then the correct inequality is

y\le\dfrac{1}{2}x+2

central angle of a sector is 72° and the sector has an area of 16.2(pie) ft^2. what is the radius of the circle?
Cloud [144]
Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

The elephants at the zoo eat 3 2/3 buckets of bananas each day. The zookeeper bought 7 1/3 buckets of bananas. How many days wil
uranmaximum [27]

Answer: 2 days

Step-by-step explanation:

The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:

= 3²/₃ = 11/3 buckets per day

The zookeeper bought 7¹/₃ which is:

= 22/3 buckets

To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:

= 22/3 ÷ 11/3

= 22/3 * 3/11

= 66/33

= 2 days

<em>If dividing fractions, multiply by the reciprocal of the second fraction. </em>
