*see attachment for the figure referred to
Answer:
4 units
Step-by-step explanation:
Given that 
, therefore, it follows that:
,
If the ratio of YW to XW = 2:1, therefore, 
Cross multiply to find XW
The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.
Invested at 7%: s
Invested at 5.5%: f
Then s+f=$15000, or f= $15000-s
Then add together the 2 interest amounts:
i = s(0.07) at 7%
i = f(0.055) at 5.5%
Then 0.07s + (15000-s)(0.055) = $952.50
Solve this for s, the amt. invested at 7%:
0.07s + 15000(0.055) - 0.055s = 952.50
Combining the s terms,
0.015s = 952.50-825
952.50-825
Then s = ------------------- = 8500
0.015
Ruth invests $8500 at 7% and $6500 at 5.5%.
Hi there
The function is
Y (x)=10000 (1-0.02)^x
Y (x)=10000 (0.98)^x
Where x is the number of time
Hope it helps
Options :
Iman has at least $12.
Iman has more than $12.
Iman has less than $12.
Iman has no more than $12
Answer:
Iman has at least $12.
Step-by-step explanation:
The inequality x ≥ 12 represents the amount of money, x that Iman has :
The inequality statement can be interpreted as ;
x greater than or equal to 12, since x represents the amount Iman has ;
The the amount of money Iman has is $12 or more
Could also be interpreted as, ; Iman has at least $12
