Answer:
406 I believe is the answer
Step-by-step explanation:
14 times 5 = 70 and add that to 21 times 16 and you get the answer
Answer:
Add all of your given parts and set them equal to 360. Your equation should look like this: U+61+2U-49+2U-32=360
Solve for U and your answer should be U=76
Answer:
x ≈ 4.2 (nearest tenth)
Step-by-step explanation:
The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).
An isosceles triangle comprises two right triangles, each with:
- base = 2 units
- height = 3.7 units
- hypotenuse = x units
Therefore, to find x use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ a² + b² = c²
⇒ 2² + 3.7² = x²
⇒ x² = 17.69
⇒ x = √(17.69)
⇒ x = 4.2 (nearest tenth)
Answer: 1.4 m/s
Explanation: the acceleration equation is a = change in velocity/change in time.
Plug the values in and you get 5.6/4
Divide and get 1.4 m/s
40 - 3k + 10k = -10 - 8k - 10
40 + 7k = -10 - 8k - 10
40 + 7k = -8k - 20
40 + 7k - 40 = -8k - 20 - 40
7k = -8k - 60
7k + 8k = -8k - 60 + 8k
15k = -60
15k/15 = -60/15
k = -4
