Murljashka [212]
A=3,500×(1+0.0485÷4)^(4×11)
A=5,947.99

6000=3500(1+0.0485/4)^4t
Solve for t to know the time needed to reach 6000
Time=11.2
So the time needed is 11 years and 2 months

Morgarella [4.7K]
Geometric is
a_n=a_1r^{n-1}
an=nth term
a1=first term
r=common ratio
n=which term

commmon ratio is like
a1 times r=a2
4 to 8
4 times 2=8
r=2

a_n=4(2)^{n-1}
the nth term is 4(2)^{n-1}

Extra points to the person who answer first
vlada-n [284]

In order to know what is the reasonable amount of tile for Mandana to order, you have to divide the choices with the area of the floor and deduct with 1 and multiply by 100. You have to assess if the answer you will get will fall between 15% and 20% which is the goal of Mandana.

<span>a.       </span>131/116.9 = (1.1206 – 1) x 100 = 12.06%, this does not fall between 15% and 20%

<span>b.      </span>138/116.9 = (1.1805 – 1) x 100 = 18.05%, this fall between 15% and 20%

<span>c.       </span>133/116.9 = (1.1377 – 1) x 100 = 13.77%, this does not fall between 15% and 20%

<span>d.      </span>141/116.9 = (1.2062 – 1) x 100 = 20.62%, this does not fall between 15% and 20%

Therefore, the reasonable amount of tile for Madana to order that is between 15% and 20% extra of the materials is 138 square feet.

A student estimates the weight of astronauts on the moon by multiplying their weight by the decimal 0.16666....what fraction can
Elden [556K]

Let x = 1.66666... ....(1)

Multiply both sides of equation (1) by 10.

10x = 1.666666.... .... (2)

Multiply both sides of equation (1) by 100.

100x = 16.66666....... (3)

Subtract equation (2) from equation (3)

100x - 10x = 16.66666...- 1.66666...

90x = 15

x= \frac{15}{90}  = \frac{1}{6}

Hence, the required fraction form is \frac{1}{6} .... Answer.
