Answer:

Step-by-step explanation:

h^2=x^2+y^2, since this is a square x=y=s so

220^2=2s^2

2s^2=48400

s^2=24200

s=24200^(1/2)m (exact)

s=155.56m (rounded to nearest hundredth of a meter)

One hectare is equal to 10000m^2

A=24200m^2(h/10000m^2)

A=2.42 hectares

A company that offers tubing trips down a river rents tubes for a person to use and "cooler" tubes to carry food and water. A gr
mestny [16]

Answer: the group rented 11 Person tubes and 4 cooler tubes

Step-by-step explanation:

There are two types of tubes, Person tube and cooler tube.

Let P represent number of Person tubes that the group rented.

Let C represent number of Cooler tubes that the group rented.

The group spends $270 to rent a total of 15 tubes and Person tube $20 Cooler tube $12.50. Two linear equations can be derived from the above information

P + C = 15 - - - - - - - 1

20P + 12.5C = 270 - - - -- - - 2

Substituting P = 15 - C into equation 2,

It becomes

20(15-C) + 12.5C = 270

300 - 20C + 12.5C = 270

- 20C + 12.5C = 270 -300

7.5C = - 30

C = 30/7.5 = 4

P = 15 - C

P = 15 - 4 = 11

4. A drawing of the top of a desk iS shown.
KATRIN_1 [288]

The area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

<h3>What is the area of a rectangle?</h3>

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

A=a\times b

Here, (a)is the length of rectangle and (b) is the width of the rectangle

A drawing of the top of a desk is shown.

  • 5 feet
  • 2 feet

The image of drawing ins not given in the problem. Here, the length of the desk is 5 feet and the width of the desk is 2 feet according to the data.

a=5\rm\; feet\\b=2\rm\; feet

Put the values in the above written formula as,

A=5\times 2A=10\rm\; ft^2

Thus, the area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

Which sets of coordinate pairs lie on the line created by the equation 2x-2=y?
Agata [3.3K]
X intercept=(1,0)
Y intercept=(0,-2)
You get x by substituting 0 for y and you get y by substituting 0 for x therefore to find y coordinates,
2(0)-2=y
0-2=y
-2=y so (0,-2)
And to find x coordinates,
2x-2=0
2x=2
2x/2=2/2
X=1 so (1, 0)
