Answer:
C
Step-by-step explanation:
Let length of rectangle be "l"
Let width of rectangle be "w"
We know,
LENGTH is 2 MORE THAN WIDTH, we can write:
l = w + 2
Also, note the perimeter is the sum of all 4 sides of a rectangle, thus:
length + width + length + width
Now,
The perimeter is given as 72, so we can write:
l + l + w + w = 72
2l + 2w = 72
We have 2 equations that we need to solve and find the length (l).
The first equation is:
l = w + 2
Rearranging, we have:
w = l - 2
We put this into 2nd equation and find the value of l:
The length is 19 meters, the correct answer is C
Step-by-step explanation:
36 : x :: x : 16
16 x 36 = x2
576 = x2
Taking square root on both sides
24 = x
4{8.2+3.7(4.4×8.8 -18.86)}=
4(8.2+3.7(38.72-18.86))=
4(8.2+(3.7)(19.86))=
4(8.2+73.482)=
(4)(81.682)=
326.728
Answer:
14.85
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A =1/2 ( 6.6)(4.5)
A = 14.85
15.87% of the population does not meet the minimum standards.
We use z-scores to find this probability:
z=(X-μ)/σ = (85-100)/15 = -15/15 = -1
Using a z-table (http://www.-table.com) we see that the area to the left of, less than, this is 0.1587. This is 15.87%.
