The answer is 2.5 cm
First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12
16-20= 4 so 4/20 is 0.2 or 20%. To get percentage move decimal to the right two times :)
5w−23<−3(3−4w)
Simplify both sides of the inequality.
5w−23<12w−9
Subtract 12w from both sides.
5w−23−12w<12w−9−12w
−7w−23<−9
Add 23 to both sides.
−7w−23+23<−9+23
−7w<14
Divide both sides by -7.
−7w/−7 < 14/−7
w > −2
Answer:
3^1
Step-by-step explanation:
3^-5 * 3^6
When multiplying exponents with the same base, we can add the exponents
3^ ( -5+6)
3^1
Given :
Rema purchased 18 ounces of gold in 2005 for $414 per ounce in order to try to diversify her investment portfolio.
She sold a third of her holdings in gold in 2009 at a price $953 per ounce. She sold the rest of her gold holdings in 2010 for $1,367 per ounce.
To Find :
What is Prema’s profit in 2009 and 2010.
Solution :
Price of one third ounces of gold, in 2005 is :
P = $414/3 = $138 .
Profit from selling them in 2009 is :
P1 = $(953 - 138) = $815 .
Profit from selling them in 2010 is :
P2 = $( 1367 - ( 414 - 138 ) ) = $1091 .
Therefore, Prema's profit in 2009 is $815 and 2010 is $1091.
Hence, this is the required solution.
