How can 7 1/5+(-8 3/5) be expressed as the sum of its integer and fractional parts
Nadya [2.5K]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is the sum of a integer and a fractional part

we have

7\frac{1}{5}+(-8\frac{3}{5})

so

7\frac{1}{5}=7+\frac{1}{5}

-8\frac{3}{5}=-8-\frac{3}{5}

substitute

7+\frac{1}{5}+(-8-\frac{3}{5})

Group terms

(7-8)+(\frac{1}{5}-\frac{3}{5})

(-1)+(-\frac{2}{5})

-1\frac{2}{5}

What is the area of the shaded region?
-BARSIC- [3]

Answer:

25π - 24 cm²

Step-by-step explanation:

area of circle:

A = πr²

A = π(5²)

A = 25π

Area of triangle:

base = 6

height = 5 - 1 = 4

(1/2)(6 * 4) = 12

there are 2 triangles so unshaded area is 24 cm²

Area of shaded region = 25π - 24 cm²
