Find the product (у- 2)(5у2 + 3y - 1)

Answers

Answer:

5y^3 - 7y^2 - 97y + 2   <<<< Answer

Step-by-step explanation:

(у- 2)(5у2 + 3y - 1)

Multiply the three terms by y

5y^2 * y + 3y * y - 1*y = 5y^3 + 3y^2 - y

Multiply the three terms by - 2

-2*5y^2 -2*3y - 2*-1

-10y^2 - 6y + 2

Now combine the like terms

5y^3 + 3y^2 - 10y^2 - y - 6y + 2

5y^3 - 7y^2 - 97y + 2

In the rectangular prism, PQ is the diagonal. Find the length of
PQ given PR = 7, RS = 4, and QS = 4.
A 4
B 9
C 12
D 15

Answers

Answer:

Option (B)

Step-by-step explanation:

Length of PR = 4

RS = 4

QS = 4

For the length of PT,

PT² = RT² + PR² [Since, PT is the diagonal of rectangle PRT]

PT² = QS² + PR² [Since, RT ≅ QS]

PT² = 4² + 7²

PT² = 16 + 49

PT² = 65

Now for the length of PQ,

PQ² = QT² + PT²

PQ² = RS² + PT² [Since, QT ≅ RS]

PQ² = 4² + 65

PQ² = 16 + 65

PQ = √81

PQ = 9

Therefore, length of diagonal PQ is 9 units.

Option (B) will be the answer.

In Heavenly Hash ice cream, the ratio of the amount of cashews to the amount of marshmallows to the amount of chocolate ice cream is 1 : 3 : 36 by volume .

What is the ratio of the amount of marshmallows to ice cream?

Ans. 41

Step-by-step explanation:

By using the formula of pythagoras theorem,

h^2 = p^2+b^2

or, h = sqrt(9^2+40^2)

or, h = sqrt(1681)

or, h = sqrt(41^2)

or, h = 41 #

Arnold has $24 to spend at the movies. His ticket is $12. He bought popcorn, candy bar, and soda. Popcorn is double the prize of the soda. The soda and candy bar are same prize. How much did he pay for the soda?

Answers

Given:

Arnold has $24 to spend at the movies.

Ticket = $12

Popcorn is double the price of the soda.

The soda and candy bar are same price.

To find:

The price for the soda.

Solution:

Let x be the price of soda.

According to the question,

Price of candy = Price of soda = x

Price of popcorn = 2(price of soda) = 2x

Total amount = Ticket + Popcorn + Soda + Candy

[tex]24=12+2x+x+x[/tex]

[tex]24=12+4x[/tex]

[tex]24-12=4x[/tex]

[tex]12=4x[/tex]

Divide both sides by 4.

[tex]\dfrac{12}{4}=x[/tex]

[tex]3=x[/tex]

Therefore, the price of soda is $3.

Blake sold 17 verses for $3.25 each he spent $16.21 on materials to make the vases what is the profit

Answers

Answer:

We can calculate what did he get, as we know he sold 17 vasess for 3.25 dollars each of them, we can multiply:

17 * 3.25 = $55.25

Now, we know he got 55.25 dollars but he spent 16.21, so we substract:

55.25 - 16.21 = $39.04

His profit selling that is of 39.04 dollars..

13. 23 boat rides; 22 are full, and the first one has 301 passengers.

12. $11,067.50

Step-by-step explanation:

13,105 people in a day, divided by 582 per ride.

13,105/582 = 22 (with a remainder)

582 x 22 = 12,804

So, the remainder is

13,105 - 12,804 = 301

23 rides, with 22 full and the first one having 301 people.
