A tablet sells for $375 at both Kade's Craft Corner and Annie's Art Shack.

1 answer:

4 0

At Kates craft corner the tablet will cost $300 because 375×20% equals 75 then you must subtract 75 from 375 to get your discount price

At Annie’s art shack the tablet will cost $337.50 because 375×10% equals 37.5 then you subtract 37.5 from 375 which will give you $337.5.

Paul and Tom both commute to work. Paul's commute on the train takes 15 minutes more than one third as many minutes as Tom's com

Ronch [10]

Answer:

45 = (one third)x + 15

Step-by-step explanation:

If x represents the number of minutes Tom commutes, then (1/3)x is "one-third as many minutes as Tom's commute." 15 minutes more than that is ...

(1/3)x + 15

We are told this is the length of Paul's commute, and that it is 45 minutes. So, the appropriate equation is ...

45 = (1/3)x +15

Gracie bought a cd for $810 that earns a 2.9 APR and is compounded quarterly. The CD matures in 5 years. How much will this CD b

enyata [817]

Answer:

The amount that this CD will be worth at maturity would be $935.90. The right answer is B.

Step-by-step explanation:

In order to calculate How much will this CD be worth at maturity we would have to use and calculate the formula of future value as follows:

Future Value=Present value×(1+i/n)∧nt

Future Value=$810×(1+2.9%/4)∧(4×5)

Future Value=$935.90

The amount that this CD will be worth at maturity would be $935.90

When asked to find a number one-tenth as large as another number, what operation would you use? What about when asked to find a

kherson [118]

Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

<u>Solution:</u>

Need to determine what operation is required to get one-tenth of a number and 10 times of a number

To get one tenth of a number, divide the number by 10.

For example to get one – tenth of 100, divide it by 10, we get 10 as a result.

$\frac{1}{10} \times 100 = 10$

To get ten times of a number, multiply the number by 10

For example 10 times of 10 = 10 x 10 = 100

Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

What is the completely factored form of x4 8x2 – 9?

Alinara [238K]

For this case we have the following polynomial:

$x ^ 4 + 8x ^ 2 - 9$

We make the following change of variables:

$u = x ^ 2$

Rewriting we have

$u ^ 2 + 8u - 9$

Factoring the second order polynomial we have:

$(u + 9) (u-1)$

Then, returning the change we have:

$(x ^ 2 + 9) (x ^ 2-1)$

Finally, we factor the expression in the parentheses of the second term:

$(x ^ 2 + 9) (x + 1) (x-1)$

Answer:

the completely factored form is:

$(x ^ 2 + 9) (x + 1) (x-1)$
