Ellen saved $2000 and she spent 10% of it to buy a bike. Kim saved 8% more than that of Ellen's left savings. If Lisa saved 60%

enyata [817]

Answer: Lis saved $1166.4 .

Step-by-step explanation:

Given , Ellen saved $2000 and she spent 10% of it to buy a bike.

Then, Ellen's left saving = saved amount - 10% of (saved amount)

= $2000 - 0.10 x $2000 <em>[We convert perecntage to decimal by diving it by 100]</em>

= $2000 - $200

= $1800

So, Ellen's left saving= $1800

Also, Kim saved 8% more than that of Ellen's left savings.

Kim's Saving = Ellen's left saving + 8% of (Ellen's left saving)

= $1800 + (0.08) x ($1800) <em>[We convert perecntage to decimal by diving it by 100]</em>

= $1800 + $144

i.e. Kim's Saving= $1944

If Lisa saved 60% as much as Kim, then Lisa's saving = 60% of (Kim's Saving)

= (0.60) x ($1944) <em>[We convert perecntage to decimal by diving it by 100]</em>

i.e. Lisa's saving = $1166.4

How do you do this?<br> Please help, I’ve been staring at this for like 10 min :)

damaskus [11]

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

$x=-2\\y=2(-2)+5\\y=-4+5\\y=1$

------

$x=-1\\y=2(-1)+5\\y=-2+5\\y=3$

------

$x=0\\y=2(0)+5\\y=0+5\\y=5$

------

$x=1\\y=2(1)+5\\y=2+5\\y=7$

------

$x=2\\y=2(2)+5\\y=4+5\\y=9$

Anna is reading a 300-page book. She can read a page in two minutes. If she has finished reading 75 percent of the pages, how ma

Daniel [21]

Answer:

150 minutes

Step-by-step explanation:

If Anna read 75% of her 300-page book, then she has already read:

300 × 75%

= 300×0.75

= 225

225 pages.

If Anna has already read 225 pages, then she has:

300 - 225 = 75

75 pages left still to read.

If Anna reads 2 minutes per page, then she has

75 × 2 = 150 minutes.

She has 150 minutes of reading left to finish her book.

By the way, it's weird to say you have 150 minutes of something to do. In real life 150 minutes = 2 1/2 hours. jfyi. Have a great day!

Find the dimensions of a rectangle with an area of 100 square feet that has the minimum perimeter.

STatiana [176]

The polygon with the shortest perimeter for a given area is a regular polygon. The regular 4-sided polygon is the square.

The side length of the square with an area of 100 ft² is √(100 ft²) = 10 ft.

The rectangle with the minimum perimeter for an area of 100 ft² is 10 ft by 10 ft.
