Answer:
97.96 cm
596.14 cm²
Step-by-step explanation:
sides become:
- 30 cm ⇒ 16 cm
- 25 cm ⇒ 11 cm
and added corners:
- 4*2πr/4= 2πr = 2*3.14*7 cm= 43.96 cm
then perimeter is:
- P= 2*16+2*11+43.96= 97.96 cm
the area left is:
- A= 30*25- 4*1/4*3.14*7²= 596.14 cm²
Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be
If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get
Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26
The answer will be yes.
Why?
Well, you know that's it's a linear equation/ function if the exponents are only 1. And by looking at this equation you'll see that there are no exponents other than 1. So the answer is yes, it is a linear equation.
