Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area, 
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.
The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
Suppose nick spent x number of tokens on day 1
So he spent x + 5 on day 2
He spent x + 10 on day 3
He spent x + 15 on day 4
He spent x + 20 on day 5
On day 6 he spent x + 25
And on day 7 he spent x + 30
So in all he spent
x + x + 5 + x + 10 + x + 15 + x + 20 + x + 25 + x + 30
= 7x + 105
But total token spent = 203
So
7x + 105 = 203
Subtracting 105 from both sides
7x = 203 - 105
7x = 98
Dividing by 7 on both sides
x = 14
So on third day he spent x + 10
= 14 + 10
= 24 tokens
Tokens spent on day 3 = 24
Answer:
12%
Step-by-step explanation:
So in the first year they sold 650 bicycles.
Second year 572.
To find percentage you'll gain the difference 650 - 572 = 78 bicycles. Divide the deficit with initial sales (650).
72/650 * 100 (as we r finding percentage).
Its should give you 12%.
Answer:
b would also equal 12.
Step-by-step explanation:
In order to find this, we simply have to note that if we have a right triangle and a 45 degree angle, then this is a 90-45-45 triangle. In these triangles, we know that the legs are the same length. So if a is 12, then so is b.
