The population of a heard of cattle numbered was 5000 to begin with and was 10,000 after 10 years. If the population was growing

Lapatulllka [165]

Answer:

$r=0.0718$ . The closest value from your given choices is C)r=0.69

Step-by-step explanation:

To solve this we are using the standard exponential growth equation:

$f(t)=A(1+r)^t$

where

$f(t)$ is the final population after $t$ years

$A$ is the initial population

$r$ is the growth rate in decimal form

$t$ is the time in years

We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so $A=5000$ , $f(t)=10000$ , and $t=10$ .

Let's replace the values and solve for $r$ :

$f(t)=A(1+r)^t$

$10000=5000(1+r)^{10}$

Divide both sides by 5000

$\frac{10000}{5000} =(1+r)^{10}$

$2=(1+r)^{10}$

Take root of 10 to both sides

$\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}$

$\sqrt[10]{2} =1+r$

Subtract 1 from both sides

$\sqrt[10]{2}-1=r$

$r=\sqrt[10]{2}-1$

$r=1.0718-1$

$r=0.0718$

We can conclude that the growth rate of our exponential equation is $r=0.0718$ . The closest value from your given choices is C)r=0.69

1 load of bricks weigh twice as much as a load of sticks. the total weight of 4 loads of each is 771 kg. What is the total weigh

liq [111]

X=brick y=sticks
x=2y
4x+4y=771
4(2y)+4y=771
8y+4y=771
12y=771
y= 771/12
y = 64.25
x = 64.25*2=128.5

Answer:
128.5+64.25*3=321.25kg

Vlada [557]

Answer:

B. 20%

Step-by-step explanation:

Step 1: Convert the 20% into a decimal which would be .20

Step 2: Multiply the cost of the meal by the converted decimal. .20×75 and your answer would give you 15.
