The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
You have to make them have the same denominator so
1/2=2/4
Then you add them together
2/4+3/4=5/4
You have to make it a mixed fraction.
4 goes into 5 one time and has a remainder of 1 so you get 1 and 1/4?
Answer:
Step-by-step explanation:
The exponential model for growth is given by :-
, where A = initial value , r = growth rate (in decimal), x = time (in years).
Given: A= 15,500 r= 3.75% = 0.0375
The exponential model for the growth of this population will be :
hence, the required model:
Answer:
False.
Step-by-step explanation:
A cylinder can be defined as a three-dimensional figure or solid shape that comprises two (2) parallel bases that are joined together by a curved surface.
Also, the surface area of a cylinder refers to the total space which is occupied by its two flat surfaces (base) and the curved surface.
Mathematically, the formula for finding the surface area of a cylinder is;
S.A = 2πrh + 2πr²
Where;
S.A is the surface area of a cylinder.
r is the radius of a cylinder.
h is the height of a cylinder.
