The value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original value of the building

Answers

Well, there is actually a formula for this kind of exercises:

n is the price the land had in the third year year

2500=n-nx0.6

2500=n(1-0.6)

2500=nx0.4

n=2500:0.4

n=6250

m is the price the land had in the second year

6250=m-mx0.6

6250=m(1-0.6)

6250=nx0.4

p=6250:0.4

p=15625

p is the price the land had in the first year

15625=p-px0.6

15625=p(1-0.6)

15625=px0.4

p=15625:0.4

p=39,062.5 <- this should be your answer. Hope this helps.

The nitro-methane fuel mixture used to power some experimental cars is 96% nitrogen dioxide and 4% methane. How many gallons of methane are needed to fill a 15-gallone fuel tank?

Answers

Answer:

0.6 gallons of methane are needed to fill a 15-gallone fuel tank.

Step-by-step explanation:

Methane is 4% of the total amount.

The total amount is of 15 gallons. So

0.04*15 = 0.4*1.5 = 0.6

0.6 gallons of methane are needed to fill a 15-gallone fuel tank.

Cayden is 6 years older than Kaylee. If Cayden is y years old, and Kaylee is x years old, which of the following equations represents the relationship between their ages?

Answers

Answer: x + 6 = y OR y = x + 6 (same equation in different format)

Step-by-step explanation: If x represents Kaylee’s age, and Cayden is 6 years older, then you must always add 6 to Kaylee’s age in order to find Cayden’s age (y).

Answer:

x + 6 = y or y - 6 = x

Step-by-step explanation:

If you know that Cayden is 6 years older than Kaylee, then x (Kaylee's age) + 6 years = y (Cayden's age). You don't know the ages of them but you still know how much older Cayden is than Kaylee.

It can also be y - 6 = x because it shows that if you subtract 6 years from Cayden's age, you get Kaylee's age.

A 13tf.ladder is leaning against the house. The top of the ladder touches the house at 10 feet above the ground.How far away is the bottom of the ladder from the house?(draw yourself a picture and label it)

Answers

Answer:

Step-by-step explanation:

I believe youd be using pythagorean theorem here. I hope this helps

The bottom of the ladder from the house is 8.30 feet away.

What is Pythagoras Theorem?

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

H= 13 feet

P= 10 feet

Using Pythagoras Theorem

B = √ H² - P²

H = √13² - 10²

B= √ 169- 100

B= √69

B= 8.30 feet

Hence, the bottom of the ladder from the house is 8.30 feet away.

MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.

Answers

Answer:

18.86 feet

Step-by-step explanation:

One rotation of the tire is equal to the circumference of the tire

The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd

where

π = 22/7

d = diameter

The size of one revolution = 2 x 22/7 = 44/7 feet

The distance covered in one rotation of the tire is 44/7 feet

The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
