Let's see. 
0.05×-0.25
125
Since there are 4 decimals places together, each factor having two, we have to add a 0.
0125
Now put it in its correct place.
0.0125
Now add a negative sign since it's a negative times a positive.
-0.0125
Now look at what they said the answer was.
-0.0125≠-1.25
So false, it equals -0.0125.

Answer:

The answer to your question is 20 feet

Step-by-step explanation:

Data

A = (-2, 1)

B = (4, 1)

C = (-2, -3)

D = (4, -3)

Process

1.- Calculate the distance from C and D

dCD = \sqrt{(4 + 2)^{2} + (3 - 3)^{2}}

dCD = \sqrt{6^{2}}

dCD = 6

2.- Calculate the distance from A to C

dAC = \sqrt{(2 - 2)^{2} + (-3 - 1)^{2}}

dAC = \sqrt{4^{2}}

dAC = 4

3.- Calculate the perimeter

Perimeter = 2(dCD) + 2(dAC)

-Substitution

Perimeter = 2(6) + 2(4)

-Simplification

Perimeter = 12 + 8

-Result

Perimeter = 20 ft

Is the square root of -11.2 a rational number?
Schach [20]
No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i.  The Sqrt(11.2) = 3.3466
so the answer is 3.3466i

a plastering contractor charges $18 per square yard( that is $2 per square foot). what is the cost of plastering 100 feet of wal
Tomtit [17]
Basically, this problem is going to require you to solve for the area and multiply it with the given cost unit.

Area = Length*Height
Area = 100 ft * 8 ft = 800 ft²

Total Cost = (Unit Cost)(Area)
Total Cost = ($2/ft²)(800 ft²)
<em>Total Cost = $1,600</em>
