Answer: There are 3 strips that can be cut from the roll of ribbon.
Step-by-step explanation:
since we have given that
Length of a ribbon is given by
Length of pieces of ribbon cut into strips is given by
So, we need to find the number of strips that can be cut is given by
Hence, there are 3 strips that can be cut from the roll of ribbon.
Answer:
456.9
Step-by-step explanation:
Let f be the fraction invested at 10%. So (1-f) is the fraction at 7%. After one year the interest is
664 = 8200 f (.10) + 8200 (1-f) (.07) = 8200(.03)f + 8200(.07)
f = (664 - 8200(.07))/(8200(.03)) = .3659 = 36.59 %
Answer: 36.59%
Check:
8200(.3659)*.1 + 8200(1-.3659)*.07 = 664.01 good
Answer:
(1, 1)
Step-by-step explanation:
in the order pair you have (x, y) so if is ( 3, 0) it means is ( x=3, y=0)
substitute in the inequality those x, and y values and see if it checks
y ≥ 4x-5
for ( 3, 0) is 0 ≥ 4*3-5 false
for ( 3,4) is 4 ≥ 4*3-5 false
for (1,1) is 1 ≥ 4*1-5 true because 1 ≥ -1
for (2, 1) is 1 ≥ 4*2-5 false
