Answer:
9r³ + 2r⁴
Step-by-step explanation:
Step 1: Write expression
4r³ + 3r⁴ - (r⁴ - 5r³)
Step 2: Distribute negative
4r³ + 3r⁴ - r⁴ + 5r³
Step 3: Combine like terms
9r³ + 2r⁴
15 36/100 / 6 is 2.56 so i think the tortoise walks 2.56 meters per minute
24•7.3%=1.752•18%=0.31536•100=31.56
Answer:
The number is 162.
Step-by-step explanation:
Let's let the number =n
So, we can set up an equation.
(n/9) is a number divided by 9.
Its "quotient" (the answer to that expression) is multiplied by 6.
6(n/9)
The product (answer) is 108.
6(n/9) = 108.
Then we can solve.
6(n/9) = 108
(n/9) = 18
n = 162
Answer: 50.24
Step-by-step explanation:
area of a quarter circle = area of the whole circle divided by 4
a = 3.14(8)² = 200.96
200.96/4 = 50.24
