Martin took a math test last week. He answered 17 correctly and 3 incorrectly. What percentage of questions did Martin answer correctly?

Answers

Answer 1
85% because 17/20 = 85/100 so 85%
Answer 2

The percentage of questions Martin answered correctly is 85%.

What is Percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Given is Martin who answered 17 questions correctly and 3 incorrectly.

Number of Correct answers = n[C] = 17

Total Number of Questions = n[T] = 17 + 3 = 20

Percentage(%) of correct questions -

(n[C] / n[T]) x 100

(17/20) x 100

1700/20

85%

Therefore, the percentage of questions Martin answered correctly is 85%.

A building with a height of 32 m casts a shadow that is 20 m long. A person standing next to the building casts a shadow that is 1.2 m long. How tall is the person?

Answers

Answer:

Building's actual height 32 meters

Building's shadow height 20 meters

Person's shadow height 1.2 meters

Person's actual height = ?

Find the person's actual height:

This is a proportion problem.

Actual height to shadow height

Building = Person

32 : 20 = x : 1.2

32 * 1.2 = 20 * x

38.4 = 20x

38.4/20 = 20x/20

1.92 = x

The person's actual height is 1.92 meters long.

32 : 20 = 1.92 : 1.2

32/20 = 1.60

1.92/1.2 = 1.60

Tony wants to ride the Medusa Roller coaster at Six Flags. He noticed there was a height requirement of 54 inches to ride the roller coaster.

If Tony is 4 feet 3 inches tall. How tall is he in inches? (Remember: One foot is 12 inches.)





Is Tony tall enough to ride Medusa? How do you know?

Answers

4* 12 + 3 = 51 inches

Answer:

If Tony is 4 feet 3 inches tall, that means he is 51 inches. So that means that Tony is not yet tall enough to ride the Medusa Roller Coaster at Six Flags yet.

Ight everyone I'm in need of some help here.
The info you'll need: The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.

On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

What is the elevation of the surf shop?
What was the distance between the deck and the ocean’s surface at 1 p.m.? Which was higher, the deck or the ocean?

-3/4 ÷ -1/8=

Answers

Answer:

6

Step-by-step explanation:

Dividing a negative by a negative will get you a positive result, so we can treat these fractions as positive numbers. To divide fractions, we take the reciprocal of the fraction we're dividing by and it'll be multiplied by the first fraction. To multiply fractions, we multiply numerator with numerator and denominator with denominator.

-3/4 ÷ -1/8 = 3/4 ÷ 1/8 = 3/4 * 8/1 = 24/4 = 6

Step-by-step explanation:

first fish tank: 95-4x

second fish tank: 40+5x

1. Define variable

The variable x represents the number of days.

2. Write the inequality

95-4x=40+5x

3. You probably don't need the answer but I am just going to solve.

The first fish tank will have less water than the second fish tank after 7 days.

95-4x=40+5x

95-4(7)=40+5(7)

95-28=40+35

67=75

Since the first equation (95-4x) represents the first fish tank, and the second equation (40+5x) represents the second fish tank, the solution shows how the amount of water in the first fish tank is less than the amount of water un the second fish tank after 7 days.

After 7 days the first tank will have less water than the second
