Your answer would be 0.5 ;)
Hope this helps
Answer:1,15 2,14 3,13 4,12 5,11 6,10 7,9 8,8 {x,y}
Step-by-step explanation:
There would be multiple answers for this question so what you have to do is find what doubles to 32 which would be 16 so you just have to find two numbers that add to 16 so the answers could be; 1,15 2,14 3,13 4,12 5,11 6,10 7,9 8,8
Answer would be 7.33 Since the last digit 5 is rounded up
Answer:
h=6 feet
Step-by-step explanation:
Given: 1. The base of a rectangle is three feet longer than its height.
2.Are of the rectangle=54 square meters
Let us say the rectangle has height h and base(breadth) b.
Since, the base of the rectangle is three feet longer than the height, we have b=h+3.
Also, Area of the Rectangle= hb
therefore, 54=h(h+3)
54= h2+ 3h
h2+3h-54=0 (Subtract 54 from both the sides)
To find the value of h we have to solve the quadratic equation.
[We have the equation in the form ax2+bx+c=0, to factorise the equation-
Step1. Find two numbers such that their multiplication is equal to ac and their addition is equal to b.
Step2. Replace b with these numbers.
Step3. Simplify the equation]
So, h2+3h-54=0
h2+9h-6h-54=0
h(h+9)-6(h+9)=0
(h+9)(h-6)=0
Which gives-
h= -9 or h= 6
As h is the height of the rectangle, h can not be -9.
so h=6 feet
and b=h+3=9 feet
So the dimensions of the rectangle are 6 feet for the height and 9 feet for the base.
