An ostrich can run 6 mph faster than a giraffe. An ostrich can run 7 miles in the same time that a giraffe can run 6 miles. Find
LUCKY_DIMON [66]

NOTE THIS IS AN EXAMPLE:

Let t = time, s = ostrich, and g = giraffe.

Here's what we know:

s = g + 5 (an ostrich is 5 mph faster than a giraffe)

st = 7 (in a certain amount of time, an ostrich runs 7 miles)

gt = 6 (in the same time, a giraffe runs 6 miles)

 

We have a value for s, so plug it into the first equation:

(g + 5)t = 7

gt = 6

 

Isolate g so that we can plug that variable value into the equation:

g = 6/t

so that gives us:

(6/t + 5)t = 7

Distribute:

6 + 5t = 7

Subtract 6:

5t = 1

Divide by 5:

t = 1/5 of an hour (or 12 minutes)

 

Now that we have a value for time, we can plug them into our equations:

1/5 g = 6

multiply by 5:

g = 30 mph

 

s = 30 + 5

s = 35 mph

 

Check by imputing into the second equation:

st = 7

35 * 1/5 = 7

7 = 7

The daily energy requirement, E (kilojoules), for a person of mass m ( kilograms) is calculated using the rule E=9m+8100
Wewaii [24]
For this case we have the following equation:
 E = 9m + 8100
 Substituting E = 8865 we have:
 8865 = 9m + 8100
 Clearing m we have:
 9m = 8865-8100
 m = (8865-8100) / (9)
 m = (765) / (9)
 m = 85 Kg
 Answer:
 
Gavin's mass is:
 
m = 85 Kg

The town of Madison has a population of 25{,}00025,00025, comma, 000. The population is increasing by a factor of 1.121.121, poi
cestrela7 [59]

Answer:

P(t)=25,000(1.12)^t

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

P(t)=a(b)^t

where

P(t) is the population in Madison

t is the number of years

a is the initial value

b is the factor of growth

we have

a=25,000\ people\\b=1.12

substitute

P(t)=25,000(1.12)^t
