Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.

Tems11 [23]

Answer and explanation:

To find : Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.

Solution :

The area of the square is given by,

$A=s^2$ where s is the side length.

We know, $1 \text{ hectare}=10,000\ m^2$

1) The area of square plot is 7 hectare.

Area in meter square is $A=7\times 10000=70000\ m^2$

Substitute the value in the formula,

$70000=s^2$

$\sqrt{70000}=s$

$264.57=s$

Side nearest to 1/10th meter is 264.8 meter.

2) The area of square plot is 12 hectare.

Area in meter square is $A=12\times 10000=120000\ m^2$

Substitute the value in the formula,

$120000=s^2$

$\sqrt{120000}=s$

$346.41=s$

Side nearest to 1/10th meter is 346.4 meter.

3) The area of square plot is 30 hectare.

Area in meter square is $A=30\times 10000=300000\ m^2$

Substitute the value in the formula,

$300000=s^2$

$\sqrt{300000}=s$

$547.72=s$

Side nearest to 1/10th meter is 547.7 meter.

If |14 -2x = 20, x could equal which of the following?

RSB [31]

Answer:

x would equal -3

Step-by-step explanation:

want to get rid of 14 from each side so 14 - 14 would get rid of that 20 - 14 = 6 now you still have a negative 2x

-2x / -2x gives you X to be alone now divide 6 with -2 which gives you -3

Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be

zalisa [80]

The absolute value of a number $x$ is the positive version of that number. So, if $x$ is positive, its absolute value is $x$ itself. If $x$ is negative, its absolute value is $-x$ , so that it will be positive again.

So, if the absolute value of a number is smaller than a certain quantity, i.e. $|x|$ it means that the positive version of $x$ is less than $a$ .

So, if $x$ is positive, the inequality becomes $x$ . If $x$ is negative, the inequality becomes $-x-a$ .

So, as a compound inequality, we have

$|x|$

So, in your case, we have

$|x-8|$

Add 8 to all sides in this inequality:

$8-0.01 < x < 8+0.01 \iff 7.79 < x$

So, on a number line, you must higlight all numbers between 7.79 and 8.01, endpoints excluded.

Conceptually, this means that the bolt measurement should be exactly 8mm, but you can accept bolts that are 0.01 millimeters shorter of larger.

X(5x2 - x)<br> Maaad confused

Naddik [55]

Move all terms to the left side and set equal to zero. Then set each factor equal to zero. Exact form:
X=0,1/5
Decimal form:
X=0,0.2
