Answer:

7 boxes

Step-by-step explanation:

The area of a rectangular prism is given by the formula ...

A = 2(LW +H(L+W))

The amount of wallpaper Carmen needs for one box is found by computing the area of the box.

__

A = 2(5·6 +7(5+6)) = 2(30 +7·11) = 2(107) = 214 . . . square feet

<h3>All boxes</h3>

Carmen will be using a total of 214x square feet of wallpaper to cover x boxes. She has 1498 ft² available, so can cover ...

1498 ft²/(214 ft²/box) = 7 boxes

Carmen has enough wallpaper to cover 7 storage boxes.

A circle with radius 5 has a sector with a central angle of 9/10 pi

Solnce55 [7]

Answer:

35.33

Step-by-step explanation:

The circle with radius 5 has a sector with a central angle of 9/10 pi.

The area of a sector is given as:

$A_s = \frac{\alpha }{2\pi} * \pi r^2$

where α = central angle of the sector in radians

r = radius of the circle

The area of the sector is therefore:

$A_s = \frac{\frac{9 \pi}{10} }{2 \pi} * (3.14 * 5^2)\\ \\A_s = \frac{9}{20} * 78.5\\\\A_s = 35.33$

The area of the sector is 35.33.

Which of the following terms refers to the level of detail of a measurement, such as the number of decimal places to which an am

Basile [38]

Answer:

Option D.

Step-by-step explanation:

Precision refers to the the level of measurement and exactness of a measurement. The mean diference between '<em>precision</em>' and '<em>exactness</em>' is that if a measuring device gives consisten measurements it's considered precise, but it's not necessarily accurate.

For example, a measurement of 2.365m is more precise than a measurement of 2.3m, given that 2.365m has more significant figures and was made with an instrument that has higher precision. This doesn't mean that the measurement is accurate, the real value could be 3m for example! ✅

Organisms A and B start out with the same population size.

Triss [41]

Answer:

At the end of ten days, the size of population B is 256 times that of population A

Step-by-step explanation:

We work under the premise that population A and B start both with the same number of individuals. Let's call such initial population $N_0$

Now, we write the exponential expression that describes population A as a function of days (t) for the first 6 days:

$N_A=N_0\,(2)^t$

which represents the starting point with $N_0$ individuals on day zero, doubling after one day (t= 1), and keeping on doubling the following days for 6 days.

So at the end of 6 days, population A would have the following number of individuals:

$N_A=N_0\,(2)^6\\N_A=N_0\,(64)\\N_A=64\,N_0$

That is 64 times the starting number of individuals.

After this, the population stops growing and starts reducing to one-half each day. This behavior can be represented by:

$N_A=64\,N_0\,(\frac{1}{2} )^t$

therefore after 4 days in this pattern, this culture has the following number of organisms:

$N_A=64\,N_0\,(\frac{1}{2} )^4\\N_A=64\,N_0\,(\frac{1}{16} )\\N_A=4\,N_0$

which is now just four times what the culture started with.

Now, on the other hand, population B grows doubling each day without interruption, so at the end of 10 days its size is given by:

$N_B=N_0\,(2)^t\\N_B=N_0\,(2)^10\\N_B=N_0\1024\\N_B=1024\,N_0$

that is it has 1024 times the initial number of organisms.

So if we compare both populations at day 10:

$\frac{N_B}{N_A} =\frac{1024\/N_0}{4\,N_0} =256$

Therefore, at the end of ten days, population B is 256 times the size of population A
