The +2 is a reminder to add when he multiply 4*1 (4*1=4+2=6)
4*2=8
4*5=20 (so he writes the 0 with a remainder of 2)
4*1=4+2=6
so,
152x4= 608
Answer:
A:4000
B:2000
C: More interest on the 4 year loan
Step-by-step explanation:
5% of 20000 is 1000 so the amount of years times the amount of interest per year. 4 years is (4x1000=4000) and 2 years is (2x1000) 4000 is greater than 2000.
if this is incorrect it is using rising interests just let me know and ill edit
Step One
======
Find the length of FO (see below)
All of the triangles are equilateral triangles. Label the center as O
FO = FE = sqrt(5) + sqrt(2)
Step Two
======
Drop a perpendicular bisector from O to the midpoint of FE. Label the midpoint as J. Find OJ
Sure the Pythagorean Theorem. Remember that OJ is a perpendicular bisector.
FO^2 = FJ^2 + OJ^2
FO = sqrt(5) + sqrt(2)
FJ = 1/2 [(sqrt(5) + sqrt(2)] \
OJ = ??
[Sqrt(5) + sqrt(2)]^2 = [1/2(sqrt(5) + sqrt(2) ] ^2 + OJ^2
5 + 2 + 2*sqrt(10) = [1/4 (5 + 2 + 2*sqrt(10) + OJ^2
7 + 2sqrt(10) = 1/4 (7 + 2sqrt(10)) + OJ^2 Multiply through by 4
28 + 8* sqrt(10) = 7 + 2sqrt(10) + 4 OJ^2 Subtract 7 + 2sqrt From both sides
21 + 6 sqrt(10) = 4OJ^2 Divide both sides by 4
21/4 + 6/4* sqrt(10) = OJ^2
21/4 + 3/2 * sqrt(10) = OJ^2 Take the square root of both sides.
sqrt OJ^2 = sqrt(21/4 + 3/2 sqrt(10) )
OJ = sqrt(21/4 + 3/2 sqrt(10) )
Step three
find h
h = 2 * OJ
h = 2* sqrt(21/4 + 3/2 sqrt(10) ) <<<<<< answer.

Answer:
Between 1991 and 2013, the infant mortality rate in the United States declined from 8.943% to 5.708 %
Step-by-step explanation:
From the information given:
The number of infant deaths under 1 year in the United States during 1991 = 36,766
The number of live births during 1991 = 4,111,000
Infant mortality rate in 1991 = 8.943%
From the data of year 2013 in the United States Record, 23,446 infants died under one year
Infant mortality rate in 1993 = 5.708 %
Between 1991 and 2013, the infant mortality rate in the United States declined from 8.943% to 5.708 % which is approximately 3%
