Answer:
r=12 as answer but as you will have reflective numbers (r12+2)(10x10)=3 in this sort of equation you will see that as they grew at a 88.3% rate 5/6 and 0.16 is a per month rate the coefficient value we can round down and call r12 = 6 for step 2 in the equation. As we can also find +0.88 which rounds to 1 and 0.33 the rate of change per month rounds to -1 and -100/12=8.3 if you are looking for the percentage. To find 6 we only need to 10/10 = 1. It is important you keep an equation simple for the growth as the change in measurement will always need a new percentage and we have a base number that can show such percentage as if it changed to 100% again at 12 inches we could reuse the equation =3-2=1 etc. or r12/100 =0.88 r=rise percentage and also be divided into 2 if we call r12 and r2 in same first equation to make r6.

Answer: 54 cm^2
Step-by-step explanation:
The area of a triangle is base*height/2.
To find the missing side of this triangle we can use pythagorean theroem. Let the unknown side = x
15^2 = 12^2+x^2
225 = 144+x^2
x^2 = 81
x = 9
Area = BH/2
Area = 9*12/2
Area = 54 cm^2
Answer:
-23/12
Step-by-step explanation:
6 3/4-8 2/3
=27/4-26/3
=3*27-26*4/12
=81-104/12
=-23/12
Step-by-step explanation:
E = m/2g(v²-u²)
2g×E = 2g×m/2g(v²-u²)
2Eg = m(v²-u²)
2Eg = mv² - mu²
mu²= mv² -2Eg
mu²/m = mv² -2Eg /m
u²= v² -2Eg
u = √v²-√2Eg
Answer:
The side length is 9 m
Step-by-step explanation:
The area of a square is given by
A = s^2
81 = s^2
Take the square root of each side
sqrt(81) = sqrt(s^2)
9 =s
The side length is 9 m
