Find the area of a circle that has a diameter = 18

Mathematics

Answer:

About 254.469 square units

Step-by-step explanation:

To find the area of a circle, you need to multiply the square of the radius by pi. To find the radius of a circle, you need to divide the diameter by 2, which in this case is 18/2=9. Now, you can plug it into the formula to find that the area of this circle is \pi \cdot 9^2 \approx 254.469. Hope this helps!

The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contai
Kryger [21]

Answer:

y = (1/2)x - 3

Step-by-step explanation:

The slope of line WX is -2.  Therefore, the slope of a line perpendicular to line WX is the negative reciprocal of -2, or +1/2.

Substitute -2 for y, -1 for x and 1/2 for m in   y = mx + b, for the purpose of finding b:

-2 = (1/2)(-1) + b.  Multiply all terms by 2 to eliminate the fraction:

-4 = -1 + b.  Then b = -3, and the desired equation is y = (1/2)x - 3.

Answer:

6 and 10

Step-by-step explanation:

Let a = the first number(3/5 of the second number namely b)

Let b = the number that is 5/3 of a

a=3/5 b

Assuming they are both positive integers, obviously you will have to add 4 to a.

4+a = b

4 + 3/5 b = b

2/5 b = 4

b = 10

a=6

ONLY ASSUMING IF THEY ARE BOTH POSITIVE INTEGERS

Tides move around Earth as bulges in the ocean. As the ocean bulges toward the moon, a high tide is created. The high tide on the side of Earth facing the moon is called the high high tide. The high tide caused by the bulge on the opposite side of Earth is called the low high tide.
