$5
Answer:
220.5cm3
Step-by-step explanation:
volume- crossectional area times lenghth
1/2 mult 7 mult 7 mult 9= 220.5cm3
Step 1. 11x -3x = 8x
Step 2. 14-11 = 3
Answer: 8x + 3
Answer:
10 + 3x </= 30
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
Step-by-step explanation:
10 + 3x </= 30
10 is the minutes for the centerpiece
3 is the minutes to make each small crane
x is the number of small cranes he can make
he has less than or equal to 30 minutes to complete them.
10 + 3x </= 30
subtract 10 from both sides
3x </= 20
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
1.a. correct
1.b. ![\sqrt{121} - \sqrt{9} = 11 - 3 = 8](https://tex.z-dn.net/?f=%20%5Csqrt%7B121%7D%20-%20%5Csqrt%7B9%7D%20%3D%2011%20-%203%20%3D%208%20)
