Hello,

g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32

h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0

==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s

25=-16*1.25²+v*1.25
==>v=50/1.25=40

Equation h=-16t²+40*t

1] add th eratio numbers together

7+1+4=12

2} write the ratio as fractions

7/12  1/12  4/12

3] use the formula (ration number/total number * number of sheeps)

a] 7/12 * 96 = 56

b] 1/12 * 96 = 8

c] 4/12 * 96 = 48

3] write your answer as a ration

If the population of a country increases at a rate of 1.5% annually, and its current population is 430,000, how many years will
Alchen [17]
For this case we have an equation of the form:
 y = A * (b) ^ t

 Where,
 A: initial amount
 b: growth rate
 t: time in years.
 Substituting values we have:
 y = 430000 * (1,015) ^ t

 By the time the population is triple we have:
 3 * 430000 = 430000 * (1,015) ^ t

 Rewriting we have:
 3 = (1,015) ^ t

 Clearing t we have:
 t = log1.015 (3)

t = 73.78876233

t = 73 years
 Answer:
 
It will take for the population to triple about:
 
t = 73 years

Are we going to start with the
romanna [79]

Answer:

multiplication.

Step-by-step explanation:

A good way to remember the order of operations is Please Excuse My Dear Aunt Sally, or PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If multiplication and division are in the same problem, you go in order. Same with addition in subtraction. What that means in this example is that since in PEMDAS, the M is first, you would multiply first instead of subtracting. :)

5(x+2)=6x+3x-14 please solve
zavuch27 [327]

Answer:

5(x+2)=6x+3x−14

Step 1: Simplify both sides of the equation.

5(x+2)=6x+3x−14

(5)(x)+(5)(2)=6x+3x+−14(Distribute)

5x+10=6x+3x+−14

5x+10=(6x+3x)+(−14)(Combine Like Terms)

5x+10=9x+−14

5x+10=9x−14

Step 2: Subtract 9x from both sides.

5x+10−9x=9x−14−9x

−4x+10=−14

Step 3: Subtract 10 from both sides.

−4x+10−10=−14−10

−4x=−24

Step 4: Divide both sides by -4.

−4x

−4

=

−24

−4

x=6

Answer:

x=6
