Which Is Not A True Proportion?

Answers

Answer 1

Answer:

C

Step-by-step explanation:

Answer 2

Answer: The answer is C

Step-by-step explanation:

If you look at the other ratios you can see a common pattern.

The top and the bottom have been multiplied by the same number.

Example: 1/2 and 7/14. Both 1 and 2 were multiplied by seven to make a true proportion.

So answer C was the only one that wasn’t multiplied by the same number.

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 24 minutes of calls is $21.64, and the remaining credit after 35 minutes of calls is $20.10. What is the remaining credit after 45 minutes of calls?

Answers

Answer:

The remaining credit after 45 minutes of calls is $18.70

Step-by-step explanation:

Here, we have a linear model to work with

Let us have the coordinates as follows;

(time calling time, credit remaining)

So we have two points as follows;

(24,21.64) and (35,20.10)

The slope will be;

(20.1-21.64)/(35-24) = -1.54/11 = -0.14

So the equation looks like;

y = -0.14x + c

To get the y-intercept, we simply substitute a point

Let us use (35,20.10)

20.10 = -0.14(35) + c

c = 20.10 + 4.9

c = 25

So the full equation is;

y = -0.14x + 25

So for 45 minutes, simply substitute 45 for x

We have this as:

y = -0.14(45) + 25

y = -6.3 + 25 = $18.70

Step-by-step explanation:

90% sure this is correct but my simple math may be wrong

Answer: x=9

Step-by-step explanation:

x^2-8x-9=0...

we can simplify this by adding 9 to each side... so it turns into this: x^2-8x=9

Then, we can turn x^2 to x*x because we know that anything to the power of two is itself multiplied by itself. So our new equation will be this:

x*x-8x=9

Now we know x has to be 9 because 8 is 1 less than 9. Therefore, our answer would be x (9)...

Let’s test this out... first, let’s substitute x with the number 9:

9^2-8*9-9=0. Simplify this:

81-72-9=0. We can then simplify furthers and we get:

0=0. This means that the equation is true

Can someone help me answer this

Answers

Answer:

x = 9

Step-by-step explanation:

56 + 3x + 7 = 90° because these angles are complementary

3x + 63 = 90 subtract 63 from both sides

3x = 27 divide both sides by 3

x = 9

3w + 6 - 4w + 3b + 2 +2b=​

Answers

The answer is 5b - w + 8

Step-by-step explanation:

Answer:

-w + 5b + 8

Step-by-step explanation:

Step 1: Since you're only dealing with addition and subtraction, the easiest method is to convert all subtraction to addition by adding the opposite. There is only one case of subtraction (-4w) which can be changed to adding negative 4w:

3w + 6 + (-4w) + 3b + 2 + 2b

Step 2: Combine like terms to simplify:

3w + (-4w) = -w

3b + 2b = 5b

6 + 2 = 8

Answer:

-w + 5b + 8

OOOO
x= -5 and x = 1
x= -1 and x = 5

Answers

Answer:

x = -5 and x = 1

Step-by-step explanation:

4( x2 + 4x + 4 ) = 36

4x2 + 16x + 16 = 36

4x2 + 16x - 20 = 0

x2 + 4x - 5 = 0

Answer:

C. x = -5, and x = 1

Step-by-step explanation:

You have the equation 4(x + 2)2 = 36

You then isolate 4 out of the equation using division on both sides

You are left with (x+2)2 = 9

Next, take square roots

[tex]\sqrt({x} +2) ^{2}[/tex] = [tex]\sqrt{9}[/tex]

This leaves you with x + 2 ± 9

So, x = -2 + 3 = 1

or

x = -2 - 3 = -5

Answers

Let ,Cynthia invested $x

Rate = 5%per year

time = 3 year

Amount

A= P(1+r/100)^t

8000=x(1+5/100)^3

8000=x(21/20)^3

x= (8000x8000)/9261

x=6910.7$
