PLEASE HELP ANSWER please answer 1-8 please its charts and its due tonight please i will give you brainleist if you answer 1-8 pleassse

Step-by-step explanation:

2. 400m÷20secs=20m/secs

3. 50m÷10secs=5m/secs

4. 90m÷45secs=2m/secs

5. 395000m÷9000secs=43.89m/secs

6. 16km÷0.25hr=64km/hrs

7. 50m÷3secs=16.67m/secs

8. 70m÷2hrs= 2hrs÷60secs=7200

70m÷7200secs=0.01m/sec

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
