Answer:

The common ratio is 5 and the 5th term is 1250

Step-by-step explanation:

The common ratio is given by

r=U(2)/U (1)

=10/2

=5

The fifth term

U (n)=ar^n-1

U(5)=2(5)^5-1

=2×5^4

=2×625

=1250

Can anyone help me with this proportion ,please?? I'm having a really hard time trying to solve it

SVEN [57.7K]

Answer:

320 pound

Step-by-step explanation:

Ratio is decently easy after u understand the concept

So... This is what the question gave

Jupitar : earth

8 : 3

In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth

Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value

Jupitar : earth

8 : 3

? : 120

Now its called ratio bcuz the increase at the same pace

So now look at the earth part, u got to find out how did 3 become 120, so just divide them

120/3 = 40 , so 3 x 40 = 120

So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)

8 x 40 = 320

Thats your answer my friend

What is the volume of a tank that can hold 18 754 Kg of methanol whose density is 0.788g/cm3

Alenkasestr [34]

Density = Mass / Volume
(0.788) = (18.754) / V
0.788V = 18.754
V = (18.754) / (0.788)
V = 23.799

For a circle with a diameter of 6 meters, what is the measurement of a central angle (in degrees) subtended by an arc with a len

Sholpan [36]

Answer:

$\boxed{\boxed{\theta=150^{\circ}}}$

Step-by-step explanation:

We know that,

$\text{Arc length}=r\cdot \theta$

where,

r = radius,

θ = central angle in radian.

Given,

diameter = 6 m, so radius = 3 m.

$\text{Arc length}=\dfrac{5}{2}\pi$

Putting the values,

$\Rightarrow \dfrac{5}{2}\pi=3\theta$

$\Rightarrow \theta=\dfrac{5}{2\times 3}\pi$

$\Rightarrow \theta=\dfrac{5}{6}\pi=\dfrac{5}{6}\times 180^{\circ}=150^{\circ}$
