Answer:
The equivalent percentage change is %
Step-by-step explanation:
Let there be a number 100
It is first increased 11 % , so the new number would be % of 100
i.e
Now, this number 111 is further increased by 13 % so the new number is % of 111
125.43
So , the total increase or equivalent increase is
%
Area=legnth times width
(3x+5)(2x+8)=360
first expand
6x²+34x+40=360
minus 360 both sides
6x²+34x-320=0
factor out 2
2(3x²+17x-160)=0
factor inner by trial and error
(2)(x-5)(3x+32)=0
set to zero
x-5=0
x=5
3x+32=0
3x=-32
x=-32/3
false, a dimention can't be negative
x=5
(3x+5)
(3(5)+5)
(15+5)
20
length is 20miiles
(2x+8)
(2(5)+8)
(10+8)
18
width is 18 miles
it is 20 miles by 18 miles
C. 402
323.24 rounded = 323
79.13 rounded = 79
323 + 79 = 402
Answer: interest = $ 3,629.34
Step-by-step explanation:
Complete question
(Marlie will be starting college next year, federal unsubsidized student loan in the amount of $18,800 at 4.29%. She knows that during this non-payment time, interest will accrue at 4.29%. Suppose Marlie only paid the interest during her four years in school and the six-month grace period. What will she now pay in interest over the term of the loan.)
This question relates to interest over a single period of time and since it's not compounded, we use formula for simple interest to calculate the interest accrued.
Data;
P = $18,800
R = 4.29% = 0.0429
T = 4.5 years
S.I = ?
S.I = PRT
S.I = 18,800 * 0.0429 * 4.5
S.I = $3,629.34
Therefore she'll need to pay $3,629.34 as interest accrued.
