Answer:
Riley will earn interest of $1706.86 in 15 years. But when the same problem solved for interest compounded annually we get,
c)1663.90
The options does not match with answer
Step-by-step explanation:
Given
principal amount P = $ 1000
rate of interest r = 6.75 % = 6.75/100 =0.0675
time t = 15
compounded semi annually, hence
no. of times interest is compounded, n = 2
We know that the formula for deriving final amount (A) is
A = P
Substituting the known values , we get
A = 1000 x
= $2706.86
Hence the interest earned = A - P
= $2706.86 - $ 1000
= $1706.86
The answer is $1706.86
But when the same problem solved for interest compounded annually we get, n=1 and so
A = 1000 x
= 2663.90
Hence interest earned = $2663.90 - $ 1000
= 1663.90
Answer:
-3,9
Step-by-step explanation:
STEP 1:
find the portion size used to freeze; subtract all cups used from total cups of chopped tomatoes
= total cups - (cups used already)
= 25 cups - (5 1/2 + 3 3/4)
convert all to improper fractions
= 25/1 - (11/2 + 15/4)
find common denominator
= 100/4 - (22/4 + 15/4)
add in parentheses
= 100/4 - 37/4
subtract numerators
= 63/4 cups left to freeze
STEP 2:
divide cups left into 3 equal portion sizes
= 63/4 ÷ 3
to divide fractions; multiply by reciprocal of 3
= 63/4 * 1/3
multiply numerators; multiply denominators
= (63*1)/(4*3)
= 63/12
simplify by 3
= 21/4
convert back to mixed number
= 5 1/4 cups
ANSWER: There are 5 1/4 cups in each portion she froze.
Hope this helps! :)
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
