Schach [20]

Answer:

20.6

Step-by-step explanation:

Since the diameter of each circle is 4, the dimensions of the rectangle is 8x12

The area of the whole rectangle is 96

Now we need to find the area of the circles

The area of 1 circle is $2^{2} *\pi =12.56$ ...

So the area of all 6 circles is 12.56*6= 75.39...

So to find the area of yellow you have to subract the area of circle from the overall area of the rectangle

96-75.4=20.6

BRAINLIEST AND 100 POINTS BRAINLIEST TO THE FIRST CORRECT ANSWER!

Nady [450]

Answer:

5 5/7

Step-by-step explanation:

-4*6/7*-5/3

We can multiply the numerators

-4 * 6*-5 = 120

We can multiply the denominators

7*3 =21

Put the numerator over the denominator

120/21

The top and bottom are both divisible by 3

120/3 = 40

21/3 =7

The new improper fraction is 40 /7

Changing from an improper fraction to a mixed number

7 goes into 40 5 times with 5 left over

5 5/7

Find the perimeter of parallelogram ABCD with vertices A(–2, 6), B(1, 2), C(–2, –2), and D(1, –6).

slamgirl [31]

Answer:

The perimeter = 26 unites

Step-by-step explanation:

* Lets revise some facts of parallelogram

- Every two opposite sides are parallel and equal

- Every two opposite angles are equal

- Every two adjacent angles are supplementary

- Th two diagonals bisects each other

- The perimeter = 2(S1 + S2)

* Now lets solve the problem

- ABCD is a parallelogram, where

A = (-2 , 6) , B = (1 , 2) , C = (-2 , -2) , D = (1 , -6)

- To find the perimeter we need the length of AB and BD

- The rule of the distance between two point is

d = √[(x2 - x1)² + (y2 - y1)²]

* Lets find AB

∵ AB = √[1 - -2)² + (2 - 6)²] = √[(3²) + (-4)²]

∴ AB = √25 = 5

* Lets find BD

∵ BD = √[(1 - 1)² + (-6 - 2)² = √[(0)² + (-8)²]

∴ BD = √64 = 8

* Lets find the perimeter

∵ The perimeter = 2 (5 + 8) = 26 unites
