Answer: See explanation: 10, 1, 1, -7

Step-by-step explanation:

I'll assume you are working with Excel. The Product function multiplies all the cells given in the specified range. Here, those are cells A2 through A5. As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2. If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Initial: 10, 5, 0, -7 B2=0

Change: 10, 1, 1, -7 B2 = -70

Other combinations are possible.

Arrange these numbers from least to greatest: 2 over 5 comma text end text − 3 over 7 comma text end text 2 over 3. A. 2 over 5

liberstina [14]

Given:
Three fractions:
1) 2/5
2) -3/7
3) 2/3

The least is -3/7 because of the negative sign. Second is 2/5, and the greatest is 2/3.

-3/7 is -0.43 in decimal form
2/5 is 0.40 in decimal form
2/3 is 0.67 in decimal form

My answer is:

Find the volume of a right prism with height h=10 cm, The base is equilateral triangle with side 4 cm, base altitude of ≈ 3.5 cm

cestrela7 [59]

<h2>Answer:</h2>

$\boxed{V=40\sqrt{3}cm^3}$

<h2>Step-by-step explanation:</h2>

A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. In a right prism every edge that connects the base and the opposite face makes right angles with both faces. Moreover, a triangular prism is a solid whose base is a triangle. In general, a prism's volume is always equal to the area of its base, which has the same area of the top face, times its height. In mathematical language:

$V=A_{b}\times H \\ \\ Where: \\ \\ A_{b}:Base \ Area \\ \\ H:Height$

Since the base is an equilateral triangle with side 4 cm, then we'll use Heron's formula to find the area. This formula uses triangle's side lengths and the semiperimeter. A polygon's semiperimeter s is half its perimeter. So the area of a triangle can be found by $A=\sqrt{s(s-a)(s-b)(s-c)}$ being $a,\:b\:and\:c$ the corresponding sides of the triangle. So:

$s=\frac{4+4+4}{2}=6cm \\ \\ a=b=c=4cm \\ \\ A_{b}=\sqrt{6(6-4)^3}=4\sqrt{3}cm^2$

Finally:

$V=4\sqrt{3}\times 10 \\ \\ \boxed{V=40\sqrt{3}cm^3}$
