write 19/25 as a decimal fist person to answer the question correctly is going to be the brainliest

Answers

0.76 is the correct answer.
So basically to change this to a decimal, you want to first change the denominator to 100. You can do this by multiplying the fraction by 4/4, which is still 1, but just with a denominator of 4.

19/25 * 4/4 = (19*4) / (25 * 4) = 76 / 100

So now you can just convert this to a decimal, and say 0.76.

S = 6ab + 4a^3
Make b the subject of the formula

Answers

Solve for b:S = 4 a^3 + 6 a b
S = 4 a^3 + 6 a b is equivalent to 4 a^3 + 6 a b = S:4 a^3 + 6 a b = S
Subtract 4 a^3 from both sides:6 a b = S - 4 a^3
Divide both sides by 6 a:Answer: b = S/(6 a) - (2 a^2)/3

​x​ 2 3 4
f(x) 5.5 7 8.5
​x​ 0 3 6
f(x) 1 8 64

Answers

​x​ 2 3 4
f(x) 5.5 7 8.5 

The first function is linear. When you subtract 5.5 from 7, you get 1.5 and when you subtract 7 from 8.5 you also get 1.5. That's how we know it's a linear function because there's clearly pattern. HOWEVER, if you had 5.5, 7, and 9 that would not be a linear function. Why? Because when you take away 7 from 9 you get 2. In order for it to be a linear function you have to get the same exact number when you subtract. 

x​ 0 3 6
f(x) 1 8 64 

The second function is exponential because when you divide you get the exact same number. 8/1 = 8 and 64/8 = 8. So this is exponential. But if you had 72 instead of 64 it would not be an exponential function because there has to be a pattern. 

I hope this makes sense. Btw I had this question on my test too and this is correct. 

Using function concepts, it is found that:

The first function is linear.The second function is exponential.

If the absolute value of the change is always the same, it is linear. If the rate is the same, it is exponential.

In the first function:

[tex]8.5 - 7 = 7 - 5.5[/tex]

Absolute value always the same, hence linear.

In the second function:

[tex]\frac{64}{8} = \frac{8}{1}[/tex]

Rate always the same, hence exponential.

D) what is the Difference between the lowest elevation in Alabama and the lowest elevation in Louisiana?


Plzzzz help me
Plz :(:

Answers

I had for homework one day! hmmmm let me seee

Answer:

Part (A) the difference is 2,415 feet.

Part (B) the difference is 3,124 feet.  

Part (C) the difference is 627 feet.  

Part (D) the difference is 8 feet.  

Step-by-step explanation:

Consider the provided table:

Part (A) The difference between the highest elevation in Alabama and lowest elevation in Louisiana.

highest elevation in Alabama is 2,407 and Lowest elevation in Louisiana is –8

Subtract the lowest elevation in Louisiana from the highest elevation in Alabama as shown:

2,407 – (–8 )= 2,407 + 8  = 2,415

So, the difference is 2,415 feet.

Part (B) the difference between the lowest elevation in New Mexico and the lowest elevation in California.

Lowest elevation in New Mexico is 2,842 and the lowest elevation in California is –282.

Subtract the lowest elevation in California from the lowest elevation in New

Mexico as shown.

2,842 – (–282) = 2,842 + 282  = 3,124

So, the difference is 3,124 feet.  

C) The difference between the highest elevation in Florida and the lowest elevation in California.

Highest elevation in Florida is 345 and the lowest elevation in California is –282.

Subtract the lowest elevation in California from the highest elevation in Florida as shown.

345 – (–282) = 345 + 282 = 627

So, the difference is 627 feet.  

Part (D) The Difference between the lowest elevation in Alabama and the lowest elevation in Louisiana.

Lowest elevation in Alabama is 0 and the lowest elevation in Louisiana is –8.

Subtract the lowest elevation in Louisiana from the lowest elevation in Alabama.  

0 – (–8) = 0 = 8

So, the difference is 8 feet.

the number of students enrolled at a college is 15,000 and grows 4% each year

Answers

I am not sure the question that you are asking here but I may be able to help you out. To figure out how many physical students that the college gains you have to multiply 15000 and 4%. However, you have to make the 4% into a decimal. In order to do that, you have to move the decimal place two places to the left. This would make 4% into 0.04. When you multiply 15000*0.04, you get 600. Then you go from there to answer whatever question you wanted answered.

The words regarding growth factor for the given blanks are a) 15000, b) 0.04, 1.04, c) 15000 × 1.04 and d) y = 15000(1.04)ˣ

What is growth factor?

The growth factor refers to a specific part of an exponential function. This is the base of an exponential function.

Given is a black statement, we need to find the words to be filled in them,

a) The number of students enrolled at a college is 15,000 and grows 4% each year,

Since, the number of students at time of enrollment is 15000, therefore, the initial amount = 15000

b) The percent rate of change is 4%, so the growth factor b is 1 + ______ = ______

Here, the percent rate of change is for growth, therefore,

the growth factor = 1 + 0.04 = 1.04

c) To find the number of students enrolled after one year, you calculate

15,000....

To find the number of students after one year = 15000 × 1.04

d) Complete the equation y = ?

The equation for the same will be  =

y = 15000(1.04)ˣ

Hence, the words regarding growth factor for the blanks are a) 15000, b) 0.04, 1.04, c) 15000 × 1.04 and d) y = 15000(1.04)ˣ

The weight of an elephant is 1000 times the weight of a cat. If the elephant weighs 14,000 pounds how many pounds does the cat weigh

Answers

To solve this problem, all you have to do is 14,000/1,000, which is 14, because the elephant weighs 14,000 lbs and the cat is 1/1000 of that weight. The cat weighs 14 pounds.
weight of the elephant= 1,000x
x= weight of the cat
14,000=1,000x
x=14 pounds is what the cat weighs.

The formula I = PRT where I = Interest, P = principal, R = rate, and T = time is used to calculate the amount of simple interest earned. Solve this formula for T.

T = I + PR
T = I – PR
T = I divided by the quantity P times R
T = IPR

Answers

Well, this is simple.
I=PRT
(Interest= Principle*Rate*Time)
So, simply divide both sides by PR
T=I/PR

Your answer is C: T = I divided by the quantity P times R
(This should have been represented as: T= I/PR)

When solving negative one over three (x − 15) = −4, what is the correct sequence of operations?

Multiply each side by negative one over three , subtract 15 from each side
Multiply each side by −3, add 15 to each side
Multiply each side by negative one over three , add 15 to each side
Multiply each side by 3, subtract 15 from each side

Answers

-1/3(x - 15) = -4

step 1 : multiply both sides by -3, step 2 : add 15 to both sides

because when u multiply both sides by -3, this cancels out the -1/3 on the left side leaving u with : x - 15 = -4 * -3.....x - 15 = 12.....and then u would add 15 to both sides....giving u : x = 12 + 15.....x = 27
