I gotcha.

Step-by-step explanation:

Condensation - water which collects as droplets on a cold surface when humid air is in contact with it.

Pressure - continuous physical force exerted on or against an object by something in contact with it.

Temperature - the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Thermal energy - (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.

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

Step-by-step explanation:

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.

-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

Explanation: the first number of the division problem stays the same but you flip the second fraction witch is 1/2 then that will be 2/1 then change the division symbol into a multiplication symbol and 3/4 times 2/1 and that equals6/4 and 6/4 is divisible by two so you divide 6/4 x 2. That equals 3/2 and you had to make that a mixed number so you divide two and 33 on the inside of the house and two on the outside. Two goes into threewants and when is your whole number and your remainder is one and one is your numerator and two is your denominator.
