18 = x% * 60

18 = x/100 * 60

18 = x/10 * 6

Multiply 10 on both sides.

180 = x * 6

6x = 180

Divide 6 on both sides.

x = 180/6

x = 30


18 is 30 percent<span> of 60.</span>

If the diagonal of a square is 11.3 meters, approximately what is the perimeter of the square?
Stells [14]

Answer:

32

Step-by-step explanation:

The diagonal of a square has a length of x sqrt(2), where x is the side length. This means the perimeter of the square is 4 (11.3/sqrt(2)), which means the perimeter is approx. 4*8, which is 32

Please help with this
omeli [17]

Answer:

y =  \frac{1}{8} x - 3

Step-by-step explanation:

Formula for straight lines:

y = mx + b

where m = slope, b = constant

Given:

y-intercept = -3 (0, -3)

m = ⅛

Substitute into formula to find b.

- 3 =  \frac{1}{8} (0) + b \\  - 3 = 0 + b \\ b =  - 3

Substitute b into original formula

y = mx + b \\ y =  \frac{1}{8} x + ( - 3) \\ y =  \frac{1}{8} x - 3

Can you figure out the formula
puteri [66]

If "a" and "b" are two values of x-coordinate, and "m" is the midpoint between them, it means the distance from one end to the midpoint is the same as the distance from the midpoint to the other end

... a-m = m-b

When we add m+b to this equation, we get

... a+b = 2m

Solving for m gives

... m = (a+b)/2

This applies to y-coordinates as well. So ...

... The midpoint between (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2)

_____

Jennifer had (x1, y1) = (-4, 10) and (x2, y2) = (-2, 6). So her calculation would be

... midpoint = ((-4-2)/2, (10+6)/2) = (-6/2, 16/2) = (-3, 8)

Brandon had (x1, y1) = (9, -4) and (x2, y2) = (-12, 8). So his calculation would be

... midpoint = ((9-12)/2, (-4+8)/2) = (-3/2, 4/2) = (-1.5, 2)
