Answers

Answer:

A reelection across the Y axis, then a reflection across the X axis.

Step-by-step explanation:

Answer:No, there isn't a transformation that maps shape I onto shape III. Translating shape I 7 units right and 7 units down will map only one of its sides onto shape III. The rest of its sides do not match up with the sides of shape III because shape III is horizontally wider then shape I.

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

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.

option B cause if you add up the 3 pizzas then it will be 30% off the whole bill instead of only 10%.

Step-by-step explanation:

hope i helped :)

Answer:

It would be option B

Step-by-step explanation:

They would save more money taking 30% off of the total of three then 10% off of each one.

For example:

If each pizza cost 10$

10% would mean 1 dollar off each pizza meaning three dollars saved in total.

If we did 3 pizzas for 30% off the original price with no discount is 30$ and with the discount is 21$.

That means you would save 9$ doing the 3 for 30% off.

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.

Answers

Answer:

25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.

Step-by-step explanation:

Answer:

Evan spent 25 percent more time. Not 125 percent.

I used a proportion to answer this questions.

20=25

100 ?

You cross multiply: 25 times 100 is 2,500. 2,500 divided by 20 is 125.

So Evan is incorrect
