Answer:
1
Step-by-step explanation:
1+1/1=2
- initial velocity=u=0m/s
- Acceleration=a=2m/s^2
- Time=t=5s
- Final velocity=v=?
Using first equation of kinematics



Answer:
Unicorn A is 300 years old
Unicorn B is 20 years old
Explanation:
15x + x = 320
16x = 320
x = 20
15 * 20 + 20 = 320
Answer:
y = $60 + 0.1 x Miles
78 = 60 +0.1x Miles
78 -60 = 0.1 x miles
(78-60)/0.1 = miles
Miles = 180
Step-by-step explanation:
Answer:
The dimensions of the rectangle are
length = 34 yards
width = 15 yards
Step-by-step explanation:
Given:
The shape is of rectangle,
Width of rectangle = x
Area of rectangle = 510 yd²
According to the given condition
Length of rectangle = 4 + 2x
To Find:
length =?
Width = ?
Solution:
We know that,

On substituting the given values we get

Which is a quadratic equation so we will apply splitting the middle term that is factorization we get
∴ 
∴ Width x = 15 yard
∴ Length = 4 + 2x = 4 +2 × 15 = 34 yard
The dimensions of the rectangle are
length = 34 yards
width = 15 yards
