Answer:

16/36 = 12/27

Step-by-step explanation:

16/36 = 12/27 ( TRUE bc its gonna leave both side of 0.44444.........)

12/ 15 = 47/50 ( FALSE bc The left side  0.8  does not equal to the right side  

0.94)

4/16 = 2/14 ( FALSE bc The left side  0.25  does not equal to the right side  0. 142857 142857142857......)

15/20 = 24/36 ( FALSE bc The left side  0.75  does not equal to the right side  

0. 6666666...........)

Therefore, 16/36 = 12/27 is the answer

What is the force of gravity (in Newtons) acting between the Earth and a 100-kg person who is on board the International Space S
ratelena [41]

Answer:

f_{G}=317877.55 N = 317.8 kN

Step-by-step explanation:

f_{G}= (G*m_{1}*m_{2})/r^{2}  \\Where:\\f_{G}= force  of  gravity\\G=gravitational constant= 6.6x10^{-11}m^{3}kg^{-1}s^{-2}\\ m_{1}= earth mass = 5.9x10^{24}kg\\m_{2}=person mass = 100kg\\r= distance between the bodies=350km= 350 000 m

kvv77 [185]

Answer:

The answer is the CD was for 3 years.

Step-by-step explanation:

First, write the equation.

I=Prt

Next, substitute the given values.

$198=$1,200×5.5%×t

Next, write the percent as a decimal.

$198=$1,200×0.055×t

Next, simplify.

$198=$66×t

Then, solve for t.

Question 18
ira [324]

Answer:

The function which represents this sequence will be:

a_n=-15n+110

Hence, option (A) is true.

Step-by-step explanation:

Given the sequence

95, 80, 65, 50, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

a_n=a_1+\left(n-1\right)d

computing the differences of all the adjacent terms

80-95=-15,\:\quad \:65-80=-15,\:\quad \:50-65=-15

As the difference is the same, so

d = -15

as

a_1=95

Thus, substituting d = -15, a_1=95 in the nth term of an arithmetic sequence

a_n=a_1+\left(n-1\right)d

a_n=-15\left(n-1\right)+95

a_n=-15n+110

Therefore, the function which represents this sequence will be:

a_n=-15n+110

Hence, option (A) is true.
