Answer:

$\frac{y}{5} + \frac{x}{5}-8$

Step-by-step explanation:

1) Simplify 2 /5y to 2y/5.

$\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2$

2) simplify 1/5x to x/5.

$\frac{2y}{5} +\frac{x}{5} -0.2y-6-2$

3) Collect like terms.

$(\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)$

4) Simplify.

$\frac{y}{5}+ \frac{x}{5} -8$

Therefor, the answer is y/5 + x/5 -8.

a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the

g100num [7]

Answer:

4 1/2 tiles are needed to cover this area

Step-by-step explanation:

Mathematically, the area of a parallelogram is the product of the base and the height

We have this as;

24 * 10 = 240 cm^2

So the area of a tile is this

The number of tiles that will cover the given area will be;

1080/240 = 4.5 tiles

AveGali [126]

The volume of a rectangular pyramid

Given a rectangular pyramid of width W, length L, and Height H, the volume is

$V=\frac{\text{WLH}}{3}$

We have to assume the pyramid given in the question has a square shape of length and width of L=34.5 feet and W = 34.5 feet, and a height of H=55 feet, thus the volume is:

$V=\frac{\text{34.5}\cdot34.5\cdot55}{3}=21,821.25ft^3$

Correct choice: A

Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given freque

bezimeni [28]

Answer:

See explanation and results below.

Step-by-step explanation:

We have the following data:

Age (yr) when award was won Frequency 25-34 31 35-44 36 45-54 12 55-64 4 65-74 6 75-84 1 85-94 2

If we order the data we got the following result. We assume that the midpoint is given by:

$Midpoint= \frac{L.Limit +U.Limit}{2}$

The $Class.Width = U.Limit-L.Limit$

And the limits are given by the lower and upper limit.

L.Limit U.Limit Class W Midpoint Frequency Limits

25 34 34-25=9 29.5 31 [25-34]

35 44 44-35=9 39.5 36 [35-44]

45 54 54-45=9 49.5 12 [45-54]

55 64 64-55=9 59.5 4 [55-64]

65 74 74-65=9 69.5 6 [65-74]

75 84 84-75=9 79.5 1 [75-84]

85 94 94-85=9 89.5 2 [85-94]
