<em>Answer:</em>

<em>1-8/27</em>

<em>Step-by-step explanation:</em>

<em />(\frac{2}{3})^3=\frac{8}{27}<em />

<em />(\frac{3}{4})^0=1<em> (anything to the zeroth power is 1)</em>

<em />1+\frac{8}{27}=1\frac{8}{27}<em />

<em>We cannot simplify, so 1-8/27 is our answer.</em>

<em>Hope this helps. Have a nice day.</em>

stepan [7]

Answer:

25a^{2}+5ab+\frac{b^{2} }{4}

Step-by-step explanation:

(5a+\frac{1}{2} b)^{2}

1. First, write out the expression without the square

(5a+\frac{1}{2} b)(5a+\frac{1}{2} b)

2. Then use foil to multiply:

5a*5a+5a*\frac{1}{2}b+\frac{1}{2}b*5a+\frac{1}{2}b*\frac{1}{2}b

=25a^{2}+5ab+\frac{b^{2} }{4}

Donald has a bunch of nickels and dimes in his piggy bank. There are 100 coins in the bank that make a total of $6.60 in change.
brilliants [131]

Answer:

78 nickels and 22 dimes

Step-by-step explanation:

Nickels = n, Dimes = d

<u>Number of coins = 100</u>

  • n + d = 100

<u>Total sum in the piggy bank = $6.60 </u>

  • 5n + 10d = 660

<u>Consider the first equation in the second:</u>

  • 5(100 -d) + 10d = 660
  • 500 - 5d + 10d = 660
  • 5d = 110
  • d = 110/5
  • d = 22
  • n = 100 - 22
  • n = 78

<u>Answer:</u> nickels 78 and dimes 22

The price of a gallon of milk was $2.65. The price rose y dollars after the last hurricane. Then the price dropped $0.15 and lat
elena55 [62]

Answer:

D

Step-by-step explanation:

So you start with $2.65 and a variable y. What we will do is work without the dollar and keep it for the end as it quite disturbs and work our way while keeping the y. So first we have 2.65. Now it rose by y so. The price = 2.65 + y. Then it dropped by 0.15. So 2.65 + y - 0.15. Here you see we have like terms so we reduce and get 2.50 + y. Now it rose by 0.05. So 2.50 + y + 0.05. Again, like terms, reduce. 2.55 + y. There you go with the answer.
