A square garden plot has an area of 75 ft2.
a. Find the length of each side in simplest radical form.
First, a square area (A) = length (l)^2
A(ft2) = l^2 --> so l(ft) = square root (sr) of A
l = srA = sr75
Next, factor out 75 into number with even roots: 25•3 = 75
So l = sr25•sr3 --> l = 5•sr3 ft
5•sr3 is in the simplest radical form
b. Calculate the length of each side to the nearest tenth of a foot.
l = sr3 = 1.732 --> so 5•1.732 = 8.66ft
Tenth is one place to the right of the decimal, so l = 8.7 ft
Answer:1st one 93 2nd 77 and 3rd 369
Step-by-step explanation:
4 x - 5 y = 9
- 5 y = - 4 x + 9 / · ( - 1 )
5 y = 4 x - 9 / : 5
Answer: d) 4
<u>Step-by-step explanation:</u>
Firstly, the gift card is worth $25.00, and each CD costs $10.98 plus a sales tax of 5.25%. 5.25% of $10.98 is $0.058 rounded off. So the total cost of each CD would be $11.038. Therefore, the number of CDs and we can buy with the $25 gift card would only be 2 CDS. $11.038 times 2 is $22.076. We have $25, so the remaining balance would be $2.924. Hope this helps.
