1. Answer;

- Triangle

Explanation;

The cross section formed by a plane that contains a vertical line of symmetry for a tetrahedron is a Triangle.

A tetrahedron also a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.

2. Answers

- Triangle

Explanation;

The cross section formed by a plane that intersects three faces of a cube is a Triangle. A cross section is the shape we get when cutting straight through an object. The shape of the cross-section of a solid depends upon the orientation of the cutting plane to the solid.

B) Find the median queuing time<br>please help!!!!​
Brilliant_brown [7]

Answer:

11 minutes.

Step-by-step explanation:

To find the median queing time from the cumulative frequency curve, we find

\frac{1}{2}  \sum \: f

and trace it on the cumulative frequency curve.

From the graph, that total frequency is 100.

Half of this 50.

We trace the 50th item.

First locate 50 on the vertical axis and trace to the horizontal axis.

This corresponds to 11.

Note that each box is 0.5 units on the queing time axis.

14. Find the Error Hiroshi is determining -42 – (-37). Find his
vaieri [72.5K]

Answer:

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.

Step-by-step explanation:

we have

Hiroshi's work

42-(-37)=42-37=5

Remember that

a negative number is just a positive number multiplied by -1

and (-1)(-1)=+1

so

Correct work

42-(-37)

42-(-1)(37)

42-(1)(-1)(37)

42+(-1)(-1)(37)

=42+37=79

therefore

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.

What is the greatest common factor of the terms 14c to the second power D and 42 C to the third power d
irina [24]

Answer:


Step-by-step explanation:

To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,


So , The given two terms can be given by

14c^2d = 2.7.c.c.d\\42c^3d =2.3.7.c.c.c.d\\

Here common numbers that are in both are

2.7.c.c.d

so GCF= 14c^2d

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal: (8.1*10^-4)^2
AfilCa [17]
<h3>Answer:</h3>
  • the result in scientific notation is 6.561×10⁻⁷
  • the result as a decimal is 0.000 000 656 1
<h3>Explanation:</h3>

The rules of exponents say the exponent outside parentheses applies to each factor inside parentheses.

... (8.1*10^-4)^2 = 8.1^2 × (10^-4)^2

... = 65.61 × 10^-8

... = 6.561 × 10^-7 . . . . adjust to scientific notation with one digit left of the decimal point

The exponent of -7 means the decimal point in the decimal number is 7 places to the left of where it is in scientific notation. That is ...

... 6.561 × 10^-7 = 0.0000006561
