Answer:

  =128 in^3

Step-by-step explanation:

To fill the rectangular prism, we are looking for the volume

V = l*w*h

V = 3.9*8.2*4.1

  V =131.118

Estimating, we can round to the nearest whole number

V = 4*8*4

  =128 in^3

Please help

Please consider the graph of the sphere.

We know that the volume of sphere is equal to \frac{4}{3}\pi r^3, where r represents radius of sphere.

We can see that diameter of sphere is 30 inches. We know that radius is half the diameter, so radius of the given sphere would be half of 30 inches that is \frac{30}{2}=15 inches.

V=\frac{4}{3}\pi r^3

V=\frac{4}{3}\pi (15\text{ in})^3

V=\frac{4}{3}\pi \times 3375\text{ in}^3

V=4\times 1125\pi \text{ in}^3

V=4500\pi \text{ in}^3

Therefore, the volume of the given sphere is 4500\pi\text{ in}^3 and option B is the correct choice.

Can someone that's very good at math please help me?

Answer:

35 :

t = 6.25 years

(about 6 years 3 months)

Equation:

t = (1/r)(A/P - 1)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = (1/0.04)((2500/2000) - 1) = 6.25

t = 6.25 years

The time required to get a total amount, principal plus interest, of $2,500.00 from simple interest on a principal of $2,000.00 at an interest rate of 4% per year is 6.25 years (about 6 years 3 months).

36:

The two distances are the same (out and back), so set them equal.

That is done by having a (rate)(time) equal a (rate)(time).

One time is “x” and the other is “4.8-x.”

One rate is 460 and the other is 500.

460 x = 500 (4.8 -x)

460 x = 2400 - 500x

900 x = 2400

x = 2.5 hours for the slower plane.

4.8- x = 2.3 hours for the faster plane.

Given that m angle G- 81", what is m angle I?<br> A)81"<br> B)89<br> C)91<br> D)99
seraphim [82]

Answer:

\text{D) }99^{\circ}

Step-by-step explanation:

Define a cyclic quadrilateral by a quadrilateral that is circumscribed by a circle. In this case, since the quadrilateral shown is circumscribed by a circle, it is a cyclic quadrilateral.

A property of all cyclic quadrilaterals is that their opposite angles are supplementary, meaning they add up to 180 degrees. Since \angle G and \angle I are opposite angles in the quadrilateral, they must be supplementary. Therefore, we have the equation:

\angle G+\angle I=180,\\81^{\circ}+\angle I=180,\\\angle I=180-81=\boxed{99^{\circ}}
