B) 4^4
C) 8^2
D) The value cannot be determined for the information​

Answers

Answer:

2¹² (Option A)

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

Any number having 0 as its exponent , the overall result will be 1. For e.g. :- [tex]a^0 = 1[/tex] (where 'a' is any number).Lets say there's a number 'a' having '- x' as its exponent , then - [tex]\frac{1}{a^{-x}} = a^x[/tex]

__________________________________________________________

Lets put random values in place of x.

Let x be 0.

Putting x = 0 in the eqn. 3x - y = 12 gives the value of y.

[tex]=> 3 \times 0 - y = 12[/tex]

[tex]=> -y = 12[/tex]

[tex]=> y = -12[/tex]

So, we can conclude that by putting x = 0 , we get y = -12.

Now , putting x = 0 & y = -12 in  [tex]\frac{8^x}{2^y}[/tex]  gives -

[tex]=> \frac{8^0}{2^{-12}} = \frac{1}{2^{-12}} = 2^{12}[/tex]

Nevada deposits $4000 in a savings account for 18 months.



The bank is paying 5% interest per year.

How much Interest will Nevada earn from the bank?



What will be the total balance in Nevada’s account after 18 months?

Answers

Answer:

nevada will earn $300 interest and the total balance after 18 months is $4,300.

Step-by-Step Explanation:

we use this following formula to find how much interest nevada has :

simple interest = principal * interest rate * time

since the amount of time is in months, we have to convert it into years. we use interest in years ONLY.

1 year = 12 months

1.5 years = 18 months

now that we have the correct values to use this formula in, we now substitute the numbers in.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

here, we converted the percentage rate into a decimal because obviously, you cannot directly multiply percentages by money or normal numbers.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

simple interest = $200 * 1.5 (we multiplied the first two values first so it's easier to get the final answer)

simple interest = $300

we now have to find the total balance on nevada's account after 18 months by using the following formula :

total amount = principal + simple interest

since we know the amount of principal and interest already, all we have to do is substitute the numbers in.

total amount = principal + simple interest

total amount = $4,000 + $300

total amount = $4,300

therefore, nevada's total balance on her account after 18 months is $4,300.

You prepare8 scoops of dog food for 4 ​dogs, and prepare15 scoops of dog food for 6 dogs. Is there a proportional relationship between the number of scoops and the number of​ dogs?
Choose the correct answer below.

Answers

Answer:

Is there a proportional relationship between the number of scoops and the number of​ dogs?

No.

Step-by-step explanation:

A proportional relationship is something like:

y = k*x

Here y can represent the number of scoops of dog food, and x the number of dogs.

First, we know that for 4 dogs he prepares 8 scoops of dog food, then:

8 = k*4

If the relationship is proportional, then we should have a similar equation for the case of 6 dogs, where he prepares 15 scoops of dog food:

15 = k*6

So if we have the same k in both equations, then there is a proportional relationship between the number of scoops and the number of dogs.

In the first equation we have:

8 = k*4

8/4 = k

2 = k

And in the second equation we have:

15 = k*6

15/6 = k

2.5 = k

The values of k are different, so no, there isn't a proportional relationship between the number of scoops and the number of dogs.

Answers

Answer:

-13

Step-by-step explanation:

Opposite of 9t = -9t

Taking the sum of 9t - 13 and -9t

Sum = 9t - 13 + (-9t)

Sum = 9t - 13 - 9t

Sum = 9t-9t - 13

Sum  = -13
