Perimeter of the shape is 2(AB) + 2(BC)

AB = sqrt((7 - 5)^2 + (3 - 5)^2) = sqrt(2^2 + (-2)^2) = sqrt(4 + 4) = sqrt(8) = 2.83
BC = sqrt((3 - 7)^2 + (0 - 3)^2) = sqrt((-4)^2 + (-3)^2) = sqrt(16 + 9) = sqrt(25) = 5

Perimeter = 2(AB) + 2(BC) = 2(2.83) + 2(5) = 5.66 + 10 = 15.7

LAN mailed a package that weighed 5.63 pounds . what is the first step in rounding this number to the nearest tenth? what is the
ankoles [38]

For this case we must follow the following rules of rounding

1) If the previous number is greater than or equal to five, then the next number increases by one unit

2) If the previous number is less than five, then the next number stays the same

Therefore, the steps for rounding to the nearest tenth is:

1) We observe that 3 is less than 5.

2) Therefore, the next number stays the same

Rounding to the nearest tenth is:

5.6

Answer:

1) We observe that 3 is less than 5.

2) Therefore, the next number stays the same

5.6

Simplify this expression 9xy4x 3x3y​
Alekssandra [29.7K]

Answer:

81 x y^5

Step-by-step explanation:

Simplify the following:

9×3×3 x y^4 y

3×3 = 9:

9×9 x y^4 y

9 x y^4×9 y = 9×9 x y^(4 + 1):

9×9 x y^(4 + 1)

4 + 1 = 5:

9×9 x y^5

9×9 = 81:

Answer: 81 x y^5

What is true of the data in the dot plot? Check all that apply.
otez555 [7]

True answers for data in the plot are

The center is 13

The center is not 14

The Peak is 14.

It has three clusters

It is not symmetric to left or right it is bi-modal.

It is has a range from 10 to 15 most number of data points are 13 to 15.

Total number times Shelly waited is 16 times.

Step-by-step explanation:

  • While taking cumulative frequency 56.75 percentage comes in 13%.
  • It is the center point of the data.
  • The 14  is not the center as it shows 93rd percent.
  • It has three clusters 0-2 has one cluster,2-4 has 2nd cluster,5-8 third.
  • It is not skewed on the left is has bi modal frequency has two heights.
  • The person indeed waited for 16 times adding total dots.
  • There was a zero 12 which created bi-modal distribution

Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps
