Igoryamba

Answer:

Fraction = $\frac{19}{50}$

Decimal = 0.38

Percent = 38%

Step-by-step explanation:

Number of shaded rectangles = 38

Total number of rectangles = 100

Fraction represented by the shaded area = $\frac{\text{Number of blocks shaded}}{\text{Total number of blocks}}$

= $\frac{38}{100}$

= $\frac{19\times 2}{50\times 2}$

= $\frac{19}{50}$

Decimal form of the shaded area = $\frac{38}{100}$ = 0.38

Percent of the shaded area = $\frac{38}{100}$ = 38%

What is the equation of a circle with center (1, -4) and radius 2?

kvv77 [185]

Answer:

(x-1)^2 + (y+4)^2 = 4

Step-by-step explanation:

The equation for a circle is given by

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-1)^2 + (y- -4)^2 = 2^2

(x-1)^2 + (y+4)^2 = 4
