If d = 20 and C = 20π, then r = 10.
If d = 26 and C = 26π, <span>then r = 13.
</span>If r = 1/2 and C = π, <span>then d = 1.
</span>If r = 7 and C = 14π, <span>then d = 14.
</span>If r = 6 and C = 12π, <span>then d = 12.
</span>If r = 50 and C = 100π, then d = 100.
*Note, r= 1/2×d or d=2×r
Answer:
25%
Step-by-step explanation:
6/24 = 0.25 = 25%
45 - 20 =??? and for the other 1... 1,400 + 7,437 = ???
Answer: -8.91, -2.8, 0.62, 4.56
Step-by-step explanation:
The negative numbers are smaller than the positive ones. The larger number behind the negative sign is smaller. Therefore, -8.91 is smaller than -2.8 so -8.91 is first and -2.8 is second. The last two numbers are positive so you compare them. 0.62 is smaller than 4.56 so the list of decimals from smallest to largest is -8.91, -2.8, 0.62, 4.56.
Hope this helps!
Answer:
Step-by-step explanation:
The initial expression is:
Using BEMDAS (Brackets - Exponents - Multiplication - Division - Addition -Subtraction), we first start with brackets:
Remember that if there is a negative sign, it will change the signs of the terms within the brackets.
Then, collecting like terms:
