Remember you can do anything as long as you to it to both sides

only differnce is that if you multiply or divide by a negative, flip the sign
from > to < or vice verca

-8x+1<25
minus 1 from both sides
-8x<24
divid both sides by -8 (don't forget to flip sign)
x>-3
H is answer

The area of a square garden is 50 m3. How long is the diagonal?

katen-ka-za [31]

Answer:

10 m

Step-by-step explanation:

If the area of a square is 50 m2, then the length of each side will be $\sqrt{50}$ m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length $\sqrt{50}$ m each.

the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:

$(hyp)^{2} = (opp)^{2} + (Adj)^{2}$ , so we have:

$(diagonal)^{2} = 50 + 50$

$(diagonal)^{2} = 100$

diagonal = 10 m

A nautical mile is a unit of distance frequently used in ocean navigation. It is defined as the length of an arc s along a great

ElenaW [278]

The length of an arc can be related to the radius of circle and the angle it makes at the center of the circle by following equation:

s = rФ

Radius is given to be = 3960 miles
We are to find the arc length in feet, so we convert the miles to feet.
1 mile = 5280 feet.
So,
Radius = 3960 x 5280 feet = 20908800 feet
Angle = 1/60 degree
The angle must be in radians before, we use its value in the equation given above.

So, 1/60 degrees in radians will be:

$\frac{1}{60} * \frac{ \pi }{180} = \frac{ \pi }{10800}$

Now we can use this value of angle in above equation to find the arc length. $s = 20908800 * \frac{ \pi }{10800} = 6080 feet$

So, rounded of to nearest 10 feet, the length of one nautical mile is 6080 feet.
