triangle abc has the coordinates in the table below. Where will the location of A' be after a dilation using a scale factor of 1.25

Answers

Answer:

B i am pretty sure

Step-by-step explanation:

The location of A' be after a dilation using a scale factor of 1.25 is (-15 , -10) .

What is scale factor?

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object.

According to the question

ΔABC has the coordinates

A(-12,-8)

B(-16,-4)

C(-4,-8)

Now,

The location of A' be after a dilation using a scale factor of 1.25

i.e

A' = (Ax* 1.25 , Ay*1.25 )

A' = (-12* 1.25 , -8*1.25 )

A' = (-15 , -10)

Hence, the location of A' be after a dilation using a scale factor of 1.25 is (-15 , -10) .

-The submarine started at 275 feet below sea level

-After one hour, the submarine is 325.8 feet below sea level. How many feet did it dive?

-After two hours, the submarine dives another 23 feet deeper.

-On hour three, the submarine descended the average of dives from hour one and two.

-Fill in chart below using the information above. Sea level is considered 0 feet.

Answers

Answer:

Step-by-step explanation:

1. if the sub is at 325.8 at it was originally at 275 you have to put the numbers in absolute value. so 325.8 - 275=50.8

the sub went down -50.8 feet to get to 325.8

if the diver dives another 23 feet you have to put the numbers in absolute value and add 325.8 + 23= -348.8 feet underwater

on hour 3 it says that it descends an average of how much he went down in the first 2 hours witch is -73.8

i got -73.8 by adding hours one and two

then you add hour 3 by -348.8

In the diagram below, what is the ratio of unshaded parts to shaded parts?

4 shaded triangles and 12 unshaded triangles.
4 unshaded to 9 shaded
9 unshaded to 4 shaded
3 unshaded to 1 shaded
1 unshaded to 3 shaded

Answers

9514 1404 393

Answer:

Step-by-step explanation:

If your description of the diagram is correct that there are 12 unshaded and 4 shaded triangles, then the desired ratio is ...

unshaded : shaded = (12 unshaded) : (4 shaded) = 12 : 4 = 3 : 1

The ratio is reduced to lowest terms by dividing both numbers by the greatest common factor, 4. The order of parts of the ratio needs to match the requested order: unshaded to shaded. The given numbers are in reverse order, requiring that you actually read and understand the question.

Answer:

the answer is 3 unshaded to 1 shaded

slope= 3/4

y=mx+b

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

The rate of change is referring to the slope, which can be calculated by rise/run. There are two points we can use to find the slope: (0,3) an (4,6), but feel free to use any points on the graph that you want to. Between those two points, the function's y value ("rise") increases by 3, while the function's x-value ("run") increases by 4. Divide 3 (rise) by 4 (run) in order to calculate the rate of change.

Suppose that a scuba diver is currently 34 feet below sea level. If he descends at a rate of 2 feet per minute, in how many minutes will it take for the diver to reach 126 feet below sea level?

Answers

Answer:

46 minutes I think

Step-by-step explanation:

Your already 34 feet down so subtract 34 from 126 which is 92. Put the two aside for a second and divide 90 by 2 which is 45 and since it take 1 minute to get down 2 feet it will take 45 to get down 90. Back to the 2, you will add one more to 45 which is 46 because it will take one more minute to get down those other 2 feet.

Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?

Answers

Answer:

Step-by-step explanation:

The number of 1-pint spray bottles she can fill with 11 gallons is 88.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 km = 1000 m

1 hour = 60 minutes

We have,

The quantity of cleaner and water mixed.

= 1 gallon + 10 gallons

= 11 gallons

Now,

1 gallon = 8 pint

Multiply 11 on both sides.

11 gallon = 88 pints

Thus,

The number of 1-pint spray bottles is 88.

When she finally emerged from underground, she got to the sidewalk and looked at the landscape. She was used to flatness and green; the farm that theyd just sold had cattle grazing as far as the eye could see. There was nothing green in sight here as cement behemoths sprung out of the ground taller than the stalks of corn back in Iowa. People zipped in front of her with briefcases tucked to their sides as high heels clacked on the pavement. It was all so overwhelming, so loud, and Hattie put her hands over her ears to shut out the sounds of the taxi horns and the thousand different conversations. Her little sister Evelyn didnt; she was trying to take it all in.Her mother pulled out a map from her purse and held it in shaky hands. According to this, our new home should be right here. Hattie traced her mothers index finger to a building that was so high that she had to crane her neck to see the top.This? Evelyn gasped.Her father, the man who was never at a loss for words, didnt say anything. He adjusted the weight of the three bags that contained most of the possessions theyd been able to bring on the three-hour plane journey that had uprooted them from their old lives and deposited them in New York City.Her father struggled to open the heavy front door, and when they were inside, the smell of hundreds of different meals clashed in her nose: spaghetti, fried chicken, fish, and curry. They stood in front of a bank of elevators as Evelyn pushed the button for the seventeenth floor. When they entered what would be their new home, Hattie spun around in tiny circles as her father gave them the grand tour.Here is where you and Evelyn will sleep, he announced. He pointed to a room that was half the size of the Iowa bedroom that was hers alone, the same Iowa bedroom where shed had all her sleepovers and whose walls still showcased the crayon scribbles from when she was a toddler. Shed tried to scrub them clean, but they were more stubborn than she was, so they would be there for the new family that would be moving in soon.Evelyn tried to sound excited. We get to share a room!Hattie was grateful for her younger sister, for the way that she could always look at the bright side of things. Hattie couldnt say anything in responseshed been speechless for most of the trip. Instead, she followed her father down the hallway that was narrow enough for one person to fit through, maybe two if they squeezed shoulder to shoulder.And here is where your mom and I will be. She could hear the forced excitement in her fathers voice for a move that he didnt want to make either. But theyd had to sell the farm, and when this opportunity presented itself, there had really been no choice.The tour was over as soon as it startedtiny kitchen, one bathroom, boxy living room. The four of them would be sharing an apartment that was smaller than the drafty old kitchen in the farmhouse.Without a word, they grabbed boxes and started about the business of unpacking in rooms that were inches away from one another rather than feet. Hattie walked over to a dirty square window in her new shared bedroom. She wiped it clean, hoping to see something that would remind her of Iowa, but the window only looked out onto more concrete and glass. A wave of sadness washed over herthe first crack in the numbness that shed been feeling for the past month since she found out about the move. She turned her back and lowered her head so Evelyn wouldnt see her, but then the sobs came, each louder than the previous one.There was a hand on her shoulder. She wanted to put the smile back on because she knew it would be better for Evelyn and everyone else that way, but she couldnt summon it now. She turned around and saw her blurry sister through tear-filled eyes. In front of her face, Evelyn was holding a folded-up picture of the whole family in front of the farmhouse.I miss it too, Evelyn began, but we dont have to forget it.Together, they taped the picture to the corner of the bedroom window so they could see it whenever they wanted.
