Answer:
r^42
Step-by-step explanation:
Just multiply the two exponents together:
(r^7)^6 = r^42
Answer:
45
Step-by-step explanation:
15 x 3 = 45 - 3 = 42
Answer:
164.73 cm²
Step-by-step explanation:
Area of the shaded area = area of semi-circle - area of the triangle
Area of the semi-circle:
Area = ½(πr²)
r = ½ of 34 = 17 cm
π = 3.14
Area = ½(3.14 × 17²)
Area = 453.73 cm²
Area of the triangle:
Area = ½*b*h
b = 34 cm
h = 17 cm
Area = ½ × 34 × 17
Area = 289 cm²
Area of the shaded area = 453.73 - 289 = 164.73 cm²
Let the numbers be 5x and 7x
so,
5x+7x = 96
12x = 96
x = 8
so, the numbers are 40 and 56
96 in the ratio of 5:7 is 40:56
