Answer:
11
Step-by-step explanation:
Focus on the product of a number and three part first
3×X=?
next it says 18 is 15 less than the product so the product is equal to
18+15=33
now Rewrite the initial equation with the product
3×X=33
now divide by three on both sides to isolate the X , that will result in
X=11
good luck!!! I believe in you!!!
Answer:
4.45 m/s
Step-by-step explanation:
Vertical distance, Sy = 5m
The speed of pebble when they hit her window :
Vx = Sx / t
We can obtain t using the relation :
Sy = 1/2 * at²
Where, a = acceleration due to gravity = 9.8m/s²
We can obtain t
5 = 1/2 * 9.8 * t²
5 = 4.9t²
t = √5/4.9
t = 1.01 seconds
Hence,
Speed, Vx = Sx / t
Vx = 4.5 / 1.01
Vx = 4.45 m/s
Answer:
7.848
Step-by-step explanation:
- Multiply the 6 and 8 to get 48
Since 48 is greater than 9, you'll have to carry the 4
- Multiply the 3 and 8 to get 24.
- And, add the carried 4 to get 28.
- Since 28 is greater than 9, you'll have to carry the 2.
