Help I Got This Wrong But I Have 2nd Chance:Tony Bought A $48 Sweatshirt And Used A Coupon For A 10%

Answers

Answer 1

Answer:

Keith paid $0.25 less than Tony paid.

Step-by-step explanation:

Tony paid ($48 - 10%) = $43.2

Keith paid $42.95.

The difference is Tony paid $0.25 more, or Keith paid $0.25 less.

Answer 2

Answer:

Keith paid $0.25 less than Tony.

Step-by-step explanation:

Tony: 48 x 0.10 = 4.8

48 - 4.8 = $ 43.20 (Tony)

Keith: $ 42.95

43.20 - 42.95 = 0.25

How to find perimeter with equations

I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much

Answers

Step-by-step explanation:

In blue colour square

Perimeter= 4 × side

= 4 (3x +7)

=12x +28 unit

In green colour square

Perimeter= 4 × side

= 4 ( 5x+1)

= 20x +4 unit

Answer:

12x + 28 = p

20x + 4 = p

Step-by-step explanation:

Assuming that both shapes are square, the perimeter of a square is the equation:

4 * x = p

Where x is the length of one side. Plug the variables in for the first square:

4 * (3x + 7) = p

Expand the brackets:

4 * 3x = 12x

4 * 7 = 28

12x + 28 = p

For the second square, plug the variables in again:

4 * (5x + 1) = p

Expand the brackets:

4 * 5x = 20x

4 * 1 = 4

20x + 4 = p

Hope this helps!

prove that 5^(2n - 1) is divisible by 8​

Answers

Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.

The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.

On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.

Let's consider a few concrete examples:

If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.

I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

Mr. Flores opened an account with a deposit of $5,000.


• The account earned annual simple interest.

• He did not make any additional deposits or withdrawals.

• At the end of 4 years, the balance of the account was $6,500.


What is the annual interest rate on this account?

A. 5.8%

B. 7.5%

C. 3.3%

D. 1.9%

Answers

Answer:

B. 7.5%

Step-by-step explanation:

First, we need the Simple Interest (S.I)

Total = Principal + Simple Interest

T = P + S.I

6500 = 5000 + S.I

[make S.I the subject of the formula]

S.I = 6500 - 5000

S.I = 1500

Simple Interest = (Principal × Rate × Time) / 100

S.I = (P × R × T) / 100

1500 = (5000 × R × 4) / 100

1500 = 20000R / 100

1500 = 200R

[divide both sides of the equation by 200]

1500 / 200 = 200R / 200

R = 1500 / 200

R = 7.5

The annual interest rate is 7.5%

A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.

Answers

Answer: y = 4x-23

Step-by-step explanation:  I'm assuming the question asks:  "A line passes through the point (4, - 7) and has a slope of 4."  I had difficulty understanding the format of the question.  Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can start with y = 4x + b, since we are given the slope.  We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.

y = 4x + b

-7 = 4(4) + b

-7 = 16 + b

b = - 23

The equation is y = 4x-23

b.g(-3) =

c. Find x when g(x) = 4.

X =
​

Answers

Given the graph of the function, where the vertex is the maximum point at (-5,4):

We can establish the quadratic function in vertex form:

g(x) = -(x + 5)^2 + 4

To find the value of g(-1):

Substitute -1 as the input of the function:

g(-1) = -(x + 5)^2 + 4

g(-1) = -(-1 + 5)^2 + 4

g(-1) = -(4)^2 + 4

g(-1) = -12



To find the value of g(-3):

Substitute -3 as the input of the function:

g(-3) = -(x + 5)^2 + 4

g(-3) = -(-3+ 5)^2 + 4

g(-3) = 0


To find the value of x when g(x) = 4:
Since your vertex is (-5, 4), in which the y-coordinate is 4, then its x-coordinate is -5.

Therefore, the value of x when g(x) = 4 is -5.
