Ok so find 20% off and see if less tha 75
percent means parts out of 100
20% means 20/100=1/5
'of' means multiply
20% of 80=1/5 times 80=16
off means subtract
disctoun tof 16 is 80-16=64
64<75
how much left over
75-spent=left over
75-64=11
anwwer is $11 left over and enough money to buy
The rationalized form of 1+ √2/1-√2 is -2√2-3
To arrange the numbers from greatest to least, we have to convert these first to similar format. I will convert the numbers to decimals:
26% = .26; 1/5 = .2; .3; .09
Now we can arrange from greatest to least -
.3, .26, .2, .09
Therefore, the correct arrangement is: .3, 26%, 1.5, .09
Answer:
n = -3 or 8
Step-by-step explanation:
2n² = 10n +48 (rearrange)
2n²- 10n - 48 = 0 (divide all terms by 2)
n²- 5n - 24 = 0
by factorization,
(n+3)(n-8) = 0
hence,
n+3 = 0 ----> n = -3
or
n-8 = 0 ----> n = 8
Answer: 1) 22cm
Step-by-step explanation:
Refer to the attachment below, the length of the rectangle is separated into three parts.
First Part = 7cm
Second Part = 4 + 2 = 6cm
Third Part = 5 + 4 = 9 cm
7 + 6 + 9 = 22
Hope this helps!! :)
