Answer:

s = 17t = 5

Step-by-step explanation:

The midpoint formula is useful here. For midpoint M, we have ...

  M = (C + D)/2

  2M = C + D

  2(10, 10) = (15, s) +(t, 3)

  (20, 20) = (15+t, s+3)

  t = 20 -15 = 5

  s = 20 -3 = 17

__

Check

  (C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

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.

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

laura has 160 pounds of green beans at her vegetable stand. she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?​

Answers

Answer:

18.75%

Calcule o saldo de salário, o funcionário foi admitido em 10 de janeiro como mensalista, salário R$ 1400,00?

Answers

Responda:

$ 980

Explicação passo a passo:

Dado que:

Salário mensal = $ 1400

Data de emprego = 10 de janeiro

Usando o sistema de mês de 30 dias:

Taxa diária =. $ 1400/30 = $ 46.66666

Dias não trabalhados = janeiro - 9 de janeiro = 9 dias

Subtraia o salário de 9 dias do total:

Salário total - (9 * taxa diária)

$ 1400 - (9 * $ 46,66666)

$ 1400 - $ 420

= $ 980

Portanto, o saldo do salário é de $ 980

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.

She sniffled and used a handkerchief to wipe away her tears. Taking a deep breath, she rapped on the door of the world's most famous detective.Mrs. Hudson answered the door and ushered the visitor to Sherlock Holmes' flat. The detective stood tall and confident, gazing at Mrs. Blakely with an inquisitive smile. He invited Mrs. Blakely to enter. Mrs. Hudson offered her some tea. After using the tea to warm her hands, Mrs. Blakely felt capable of explaining her situation. Yesterday afternoon, Mrs. Blakely had arrived home to find a masked individual robbing her house. When the mysterious figure heard her approach, he or she ran farther into the house and disappeared. All that remained was the black mask lying on the ground. Mrs. Blakely's most prized possession, a massive purple gem, also had disappeared. While Mrs. Blakely knew it would be useless to ask Holmes to retrieve the gem, she wanted him to determine how the thief and gem had disappeared so completely.Sherlock Holmes listened to the tale and agreed to visit the crime scene. The safe was open and empty, but it was not damaged. There was no visible entry into the room where the safe was kept: the windows were sealed, and the door was not damaged. Mrs. Blakely led Sherlock Holmes farther into the house and stopped in the middle of a hallway of old portraits. There were no windows, and the only door was at the other end of the hallway."This spot is where I found the black mask," Mrs. Blakely explained.Sherlock Holmes inspected the hallway with a wrinkled brow. He walked up and down the hallway. He put his hand on the smooth floor. Then, Sherlock's brow smoothed and a glint entered his eyes. Turning to the wall, he pressed the expensive portrait into the wall."What are you doing to my painting?" Mrs. Blakely gasped."Calm down, Mrs. Blakely," Holmes replied. "The solution to this mystery is staring you in the face. There is no sign of a break in, so the thief has access to the house. The thief disappeared in this spot without using the far door, so there must be a hiding spot within the walls or floor. There are scratches on the ground near this portrait. I felt a draft when I reached down to test the floor. It's elementary, Mrs. Blakely. The thief is hidden in the wall behind this portrait."Holmes pushed the portrait harder into the wall. The wall moved, revealing a hiding place. Sherlock Holmes lit a candle. Its light revealed a sleeping maid with a gigantic purple gem clasped in her hands. The mystery of the disappearing thief was solved.Select the detail that supports this statement: Mrs. Blakely was upset when she arrived to speak with Sherlock Holmes.
