To win a game, you need at least 45 points. Each question is worth 3 points. Write and solve an inequality that represents the number of questions you need to answer correctly to win the game.

Answers

Answer:

$3x\geq 45$ ; At-least 15 questions.

Step-by-step explanation:

Let x represent the number of questions you need to answer correctly..

We have been given that each question is worth 3 points. The points earned from answering x right questions would be $3x$ .

Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:

$3x\geq 45$

$(3x)/(3)\geq (45)/(3)$

$x\geq 15$

Therefore, you need to answer at-least 15 questions correctly to win the game.

3x=45
(divide each side by 3)
x=15
You need to answer 15 correctly.

A boat is marked up 20% on the original price. The original price was $50. What is the sale price of the boat before sales tax?

Answers

The price of the boat before sales tax is $60.

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Gien that, the boat is marked up 20% of the original price of $50.

Therefore, the price of the boat is:

50 + 20% of 50

= 50 + 20×50/100

= 50 + 10

= 60

Hence, the price of the boat before sales tax is $60.

The total cost for a bowling game includes the fee for the shoe rental plus a fee per game. The cost of each game increases the price by $4. After 3 games, the total cost with the shoe rental is $14. A:Write an equation to represent the total cost y to rent shoes and bowl x number of games.
B: How much is the shoe rental?

Answers

Y= shoe rent (s) + cost of each game (B) times (x) number of games played total.

they played 3 games total 1st the cost of $4each game. ---> 4 times 3= $12

after those 3 games, the total cost was $12 without including the shoe rental.
--->total charged minus cost of all games=shoe rental cost
--->$14-$12=$2
shoe rental=$2

Identify the two-dimensional shape of the cross section if a cube is sliced horizontally. Then identify the two-dimensional shape of the cross section ifa cube is sliced vertically.
Explain why the shape are the same or different

Answers

[see the pictures attached for a better understanding !]

Horizontal cross section : we get a square in the horizontal plane, its side is the same as the cube's.

Vertical cross section : we get a square in the vertical plane, its side is the same as the cube's.

Hence, the two shapes are the same (two squares with same sides are the same)

-- First of all, you haven't specified how the cube itself is situated.
That would make a difference.
Is it sitting flat on one of its faces ?
Standing on one vertex ?
Standing on one edge ?

-- If I assume that the cube is sitting on a level, horizontal table, flat
on one of its faces parallel to the table and in contact with it, then ANY
slice that is parallel to any face, whether horizontal or vertical, reveals
a square cross section, congruent to any face of the cube.
