Answers

Answer 1
Answer:

Answer:

z = -8.46 - 3.08i.

Step-by-step explanation:

cos 200 = -0.93969 so 9 * cos 200 = -8.46 to the nearest hundredth.

sin 200 = -0.3420 so 9 * sin 200 = -3.08 to nearest hundredth.

What is 216÷18 using base ten blocks

Answers


the blocks for this one is 216 tenths and 18 ones


Final answer:

To solve 216 ÷ 18 using base ten blocks, we need to divide the base ten blocks into 18 groups and determine the result.

Explanation:

To solve 216 ÷ 18 using base ten blocks, we can start by representing the dividend, 216, using base ten blocks. We can use 2 hundred blocks, 1 ten block, and 6 one blocks. Next, we need to divide these blocks into 18 groups.

We start by grouping the hundred blocks. We can fit 1 hundred block into 18 groups, which leaves us with 1 hundred block remaining. We then move to the ten block, which we can fit 17 groups into, leaving us with 1 ten block remaining. Finally, we divide the 6 one blocks into 18 groups, but since 18 is greater than 6, we cannot form any complete groups with the remaining ones. Therefore, the quotient is 1 hundred, 1 ten, and 0 ones, which we can rewrite as 110.
