Suppose on April 1, a gag store sold a total of 27 widgets and wombats combined. If widgets cost
$0.75, wombats cost $1.25, and the store received a total of $27.75 for these two items, how
many of each item did the store sell?

Answers

Answer:

Widgets: 12

Wombats: 15

Step-by-step explanation:

Let x represent widgets

y represent wombats

Set up the equations

(1) x + y = 27

(2) 0.75x + 1.25y = 27.75

Solve equation (1), x + y = 27 for x

x = 27 - y

Substitute 27- y for x into equation (2)

0.75(27 - y) + 1.25y = 27.75

0.5y + 20.25 = 27.75

0.5y = 7.5

y = 15

Substitute 15 for y into equation (2)

x = 27 - 15

= 12

Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where x is the number of years since he bought his truck.

In how many years will his truck be worth $4,800?

Answers

Answer:

28 years

Step-by-step explanation:

The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

            solving for Table Weight       substract Book Weight from both sides

Total wieght of the barricade - Book Weight  = Table Weight

                   310 - 8(30)  =  Table Weight

                   310  - 240   = Table Weight

Sara was thinking of a number. Sara adds 12, then divides by 7 to get an answer of 11. What was the original number?

Answers

Answer:

65

Step-by-step explanation:

Do the opposite of what the question gives you.

Sara has the number 11. She divided by 7, so you would multiply by 7:

11 x 7 = 77

Next, Sara added 12, so you will subtract by 12:

77 - 12 = 65

65 is the number Sara was thinking of.

which of the following is a difference of cubes?
a. 3x^9-64y^3
b. 15x^21-64y^3
c. 27x^15-9y^3
d. x^6+27y^9

Answers

Answer:

D: x^(6) + 27y^(9)

Step-by-step explanation:

A) 3x^(9) - 64y^(3)

The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.

B) 15x^(21) - 64y^(3)

Similar to the reason given in A above, the first term cannot be expressed as a cube.

C) 27x^(15) - 9y^(3)

In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.

D) x^(6) + 27y^(9)

This can be expressed as;

(x²)³ - (-3y³)³

This is therefore a difference of cubes

A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?

–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5

Answers

Answer:

n^2 + 6n + 1

Step-by-step explanation:

Firstly, we have to evaluate AB

What we have to do is to multiply A and B

We have this as;

n(2n + 6) = 2n^2 + 6n

Now, we have to subtract the value of C from here and that is;

(2n^2 + 6n) - (n^2 - 1)

2n^2 + 6n - n^2 + 1

= 2n^2 -n^2 + 6n + 1

= n^2 + 6n + 1

Step-by-step explanation:

Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.

If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.

Answers

Answer: No he would have 8.5$

Step-by-step explanation:

15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short

If Eric buys the jumper, he will not have £10 left to give to his sister.

To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.

Initial amount Eric has = £15

Cost of the scarf = £8.50

Amount received from his nan = £20

Cost of the jumper = £18

Amount to give to his sister = £10

First, let's calculate Eric's remaining balance after buying the scarf:

Remaining balance = Initial amount - Cost of the scarf

Remaining balance = £15 - £8.50

Remaining balance = £6.50

Next, let's calculate Eric's balance after receiving money from his nan:

Total balance = Remaining balance + Amount received from nan

Total balance = £6.50 + £20

Total balance = £26.50

Now, let's check if Eric can still afford to buy the jumper:

If Eric buys the jumper:

New balance = Total balance - Cost of the jumper

New balance = £26.50 - £18

New balance = £8.50

The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.

Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.
