Answer:

$76.32

Step-by-step explanation:

First, add up all the costs for everything:

17 + 30 + 25 = 72

Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).

(72)(1.06) = 76.32

Therefore the total cost of everything Walter bought plus the tax rate is $76.32.

I hope this helps!!

What would be the difference at the end of one year between the simple interest earned on a deposit of $450 at 4.5% and the comp

Len [333]

Answer: $0

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 1 year

P = $450

R = 4.5%

Therefore

I = (450 × 4.5 × 1)/100

I = 2025/100

I = 20.25

For compound interest,

Initial amount deposited into the account is $450 This means that the principal,

P = 450

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 4.5%. So

r = 4.5/100 = 0.045

It was compounded for just a year. So

t = 1

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 450 (1+0.045/1)^1×1

A = 450(1.045) = $470.25

Compound interest = 470.25 - 450 = 20.25

The difference is 20.25 - 20.25 = 0

Suppose Ax = b has a solution. Explain why the solution is unique precisely when Ax = 0 has only the trivial solution. Choose th

son4ous [18]

Answer:

B. Since Ax-b is consistent, its solution set is obtained by translating the solution set of Ax=0. So the solution set of Ax = b is a single vector if and only if the solution set of Ax= 0 is a single vector, and that happens if and only if Ax 0 has only the trivial solution.

Step-by-step explanation:

the answer to the question is answer B. and here is the explanation below

let us imagine that the equation ax = b has a solution

now our goal will be to show that the solution of ax =b when ax = 0 has only trivial solution.

ax = 0 is homogenous

if this equation was consistent for b, we define

ax = b to be a set of vector that has the form

w = m + gh(h is a subscript)

gh is a solution of ax = 0

from what we have above, ax=b is in the form ofw= m+gh

with

m = solution of ax=b

gh = soulution of ax=0

ax = 0 has only trivial solution

gh = 0

with gh = 0

ax=b is w=m

so ax = b is unique.

Solve: 28 − ≥ 7( − 4) (show your work) real answers only pls :(

ohaa [14]

You’ll distribute the 7 from (x-4) so your equation will be
28-x>_ 7x-28
then you’ll combine like terms (-x and 7x and 28 and -28
-56>_ -8x
divide by -8 on both sides and flip your sign
you’re answer is x<_7
x is less then or equal to 7
