Find the minimum and maximum possible areas for a rectangle measuring 4.15 cm by 7.34 cm. Round to the nearest hundredth. A. min
Shalnov [3]

This is probably in the context of a discussion of significant figures and accuracy.

When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to  41.155 cm

Similarly 7.34 really means between 7.335 and 7.345 cm.

The minimum area rectangle is 

4.145 \times 7.335 = 30.403575 \approx 30.40

The maximum area rectangle is

4.155 \times 7.345 =30.518475 \approx 30.52

Choice A

Tju [1.3M]

Answer: 10

<u>Step-by-step explanation:</u>

 (\frac{1}{2}+\frac{3}{4})÷\frac{1}{8}

= (\frac{1}{2}(\frac{2}{2})+\frac{3}{4})÷\frac{1}{8}

= (\frac{2}{4}+\frac{3}{4})÷\frac{1}{8}

= (\frac{5}{4})÷\frac{1}{8}

= (\frac{5}{4})x\frac{8}{1}

= \frac{40}{4}

= 10

27^4–9^5 3^9 is divisible by 25
hichkok12 [17]

Answer:

  no

Step-by-step explanation:

If you mean

  27^4 - 9^5·3^9 = -1161730026

it has no factors of 5, so cannot be divisible by 25.

__

If you mean ...

  (27^4 -9^5)/3^9 = ((3^3)^4 -(3^2)^5)/3^9 = 3^10(3^2 -1)/3^9 = 3(9-1) = 24

it is not divisible by 25, either.

Please help
earnstyle [38]

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.
