Answer:

2 ounces of nuts are needed to make one cake.

Step-by-step explanation:

if he uses 1.4 to make 1/8 of a cake, then you need to do it 8 times to make a full cake. Multiply 1/4 * 8 which is equal to 8/4 which simplifies to 2. This is your answer!

2 ounces of nuts are needed to make one cake.

The population of rabbits on an island is growing exponentially. In the year 1994, the population of rabbits was 9600, and by 20

Answer:

49243

Step-by-step explanation:

Given that the population of rabbits on an island is growing exponentially.

Let the population, $P=P_0e^{bt}$

where, $P_0$ and b are constants, t=(Current year -1994) is the time in years from 1994.

In 1994, t=0, the population of rabbit, P=9600, so

$9600=P_0e^{b\times 0}$

So, $P_0=9600$

and in 2000, t=2000-1994=6 years and population of the rabbit, P=18400

$18400=9600 \times e^{b\times 6} \\\\\frac{18400}{9600}=e^{b\times 6} \\\\$

$\ln(23/12}=6b \\\\$

$b = \frac{\ln{1.92}}{6} \\\\$

b=0.109

On putting the value of P_0 and b, the population of the rabbit after t years from 1994 is

$P=9600 \times e^{0.109\times t}$

In 2009, t= 2009-1994=15 years,

So, the population of the rabbit in 2009

$P=9600 \times e^{0.109\times 15}=49243$

Hence, the population of the rabbit in 2009 is 49243.

Which algebraic expression models the given word phrase 10 times the sum of a and b?

Phoenix [80]

In this case, the answer would be 10(a+b). We are multiplying 10 * a + b. Hope this helps you and satisfies your query. Feel free to ask more questions.

Question 4

laiz [17]

Answer:

I just solved a question similar to this

Let's understand it

It's saying she got 660 or it is that her weekly pay is 660

So now let weekly pay which is P be 660

Hence the formulae is given

It's 480 + 18 (h – 30) = 660

Now its just boring calculation

If you mark it brainleist I will do the calculation for you wink wink

Never mind

480 + 18 (h – 30) = 660

18 (h – 30) = 660-480

18 (h – 30) = 120

(h – 30) = 120/18

(h – 30) = 6.6

h = 6.6+30

h= 36.6

So dam the Judy lady worked for 36.6 hours

Dafna11 [192]

Answer: Parallel

I believe that if you set up these equations into y = mx + b form, you're able to notice that the slope is the same for each equation. That causes the answer to be parallel
