Answer:
7.5 years
Step-by-step explanation:
P = $5000,
R = 4.25%,
A = $6593.75,
N =?
SI = A - P = 6593.75 - 5000 =$1593. 75
![\because \: SI = \frac{ PNR}{100} \\ \\ \therefore \: 1593.75 = \frac{5000 \times N \times 4.25}{100} \\ \\ \therefore \: 1593.75 \times 100 = 21,250 \times N \\ \\ N = \frac{159375}{21250} \\ \\ N = 7.5 \: years \:](https://tex.z-dn.net/?f=%20%5Cbecause%20%5C%3A%20SI%20%3D%20%5Cfrac%7B%20PNR%7D%7B100%7D%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%201593.75%20%3D%20%20%5Cfrac%7B5000%20%5Ctimes%20N%20%5Ctimes%204.25%7D%7B100%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%201593.75%20%5Ctimes%20100%20%3D%2021%2C250%20%5Ctimes%20N%20%5C%5C%20%20%5C%5C%20N%20%3D%20%20%5Cfrac%7B159375%7D%7B21250%7D%20%20%5C%5C%20%20%5C%5C%20N%20%3D%207.5%20%5C%3A%20years%20%5C%3A%20)
Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
Let
rA--------> radius of the circle A
rB-------> radius of the circle B
SA------> the area of the sector for circle A
SB------> the area of the sector for circle B
we have that
rA=5/2 ft
rB=9/2 ft
rA/rB=5/9-----------> rB/rA=9/5
SA=(25/36)π ft²
we know that
if Both circle A and circle B have a central angle , the square
of the ratio of the radius of circle A to the radius of circle B is equals to
the ratio of the area of the sector for circle A to the area of the sector for
circle B
(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->
<span>SB----------- > (81/25)*(25/36)------ > 81/36------
> 9/4π ft²</span>
the answer is
<span>the measure of the sector for circle B is (9/4)π ft²</span>
