Answer:
3/10 of the whole cake
Step-by-step explanation:
When you divide a cake in halve you get 5 pieces on each side, if Kim ate 3/5 of 1/2 of the cake, then she ate 3 pieces, so she ate 3/10 of the cake, and other way to figure this out is multiplying the two fractions, 3/5 x 1/2 = 3/10
Answer:
7 inches
Step-by-step explanation:
area of square=l^2
49=l^2
=l
7=l
therefore the sides of a triangle is 7 inches.
Answer:
30
Step-by-step explanation:
Complementary angle to B = 90 - 60 = 30
9x^2 -c =d
add c to each side
9x^2 = c+d
divide by 9
x^2=(c+d)/9
take the square root on each side
x = +- sqrt ((c+d)/9)
simplify
x = +- 1/3 sqrt (c+d)
Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)
5*2400=$12,000 is the total costs for 5 decks costing $2,400 each.
