Green

Radius: 16/2=8cm

Diameter: 16cm (given)

Formula: I'm not sure what formula this chart is asking for. But assuming it's the formula for circumference that would be 2πR (2 times pi (3.14) times the radius). If this isn't the formula the chart is looking for let me know what formula you need and I'll try to help you out with that

Circumference: 2pi Radius=2(3.14)8=50.24 cm

Yellow

Radius: 11/2=5.5

Diameter: 11cm (given)

Formula: 2πR

Circumference:2 pi R=2(3.14)5.5 =34.54 cm

Pink

Radius: 1 cm

Diameter: 2 cm

Formula: 2πR

Circumference: 2piR=2(3.14)1=6.28 cm

What is the solution to the following system densations?

givi [52]

Answer:

D. (2, 1)

Step-by-step explanation:

Given:

y = 6x - 11

-2x - 3y = -7

Required:

Find the solution.

Solution:

y = 6x - 11 ---› eqn. 1

-2x - 3y = -7 ----› eqn 2

Substitute y = (6x - 11) into equation 2.

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-20x + 33 = -7

Subtract 33 from each side

-20x = -7 - 33

-20x = -40

Divide both sides by -20

x = -40/-20

x = 2

Substitute x = 2 into equation 1.

y = 6x - 11 ---› eqn. 1

y = 6(2) - 11

y = 12 - 11

y = 1

The solution is very (2, 1)

The length of a rectangle is 7 meters longer that it’s width. What is the width of this rectangle if it’s perimeter is equal to

dolphi86 [110]

The width of rectangle is 21 meters.

Step-by-step explanation:

Given,

Perimeter of rectangle = 98 meters

Width of rectangle = w

Length of rectangle = w+7

Perimeter of rectangle = 2(Length+Width)

Perimeter = $2(w+7+w)$

$98=2(2w+7)\\98=4w+14\\98-14=4w\\84=4w\\4w=84$

Dividing both sides by 4

$\frac{4w}{4}=\frac{84}{4}\\w=21$

Width of rectangle = 21 meters

The width of rectangle is 21 meters.
