Answer:

14.8\text{ Units}^3

Step-by-step explanation:

We have been given that the base area of a right pyramid with hexagonal base is 7.4 square units. The pyramid has a height of 6 units.

To find the volume of the given pyramid we will use formula:

\text{Volume of hexagonal pyramid}=\text{ Base area}\times \frac{\text{Height}}{3}

\text{Volume of hexagonal pyramid}=7.4\text{ Units}^2\times \frac{\text{6 units}}{3}

\text{Volume of hexagonal pyramid}=7.4\text{ Units}^2\times \text{2 units}

\text{Volume of hexagonal pyramid}=14.8\text{ Units}^3

Therefore, the volume of given hexagonal pyramid is 14.8 cubic units.

Answer:

14.8 cubic units

Step-by-step explanation:

The volume of the right pyramid can be calculated using formula

V_{pyramid}=\dfrac{1}{3}\cdot A_{base}\cdot height.

You are given

A_{base}=7.4\ un^2.\\ \\height=6\ un.

Then

V_{pyramid}=\dfrac{1}{3}\cdot 7.4\cdot 6=2\cdot 7.4=14.8\ un^3.

Can someone with knowledge see what I did wrong on number 4<br>also see if number 3 is right​
Yakvenalex [24]

Answer:

#4.  m=0;

#3.  m = \frac{-1}{2}

Step-by-step explanation:

It seems right.

#4.  

Maybe your teacher wants you to write m=0; because when a fraction has a numerator equal to zero then the fraction is zero.

#3.

Maybe your teachers want you to simplify the fraction and write m = \frac{-1}{2}

Aiden buys two bags of chips at $1.09 each and a 20 ounce soda for $1.20 at the gas station.He knows that the state tax is 5.5.
Natalka [10]
Aiden will receive $1.43 from a $5 bill.

If the state tax is 5.5%, you can use the equation below to solve for the total cost, <em>t</em>.

<em>t</em> = 1.055 (2 × 1.09 + 1.20)
<em>t</em> = 1.055 (2.18 + 1.20)
<em /><em>t </em>= 1.055 (3.38)
<em>t </em>= 3.5659

You can round 3.5659 to $3.57. Finally, you subtract 3.57 from 5 to find the amount of change Aiden will receive, <em>c</em><em />.

<em>c </em>= 5 - 3.57
<em>c </em>= 1.43

A rectangle with a perimeter of 19m^2+2m-10 and a width of m^2 write an expression for the lenght
never [62]

Answer: \frac{17}{2}m^2+m-5

Step-by-step explanation:

By definition, the perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght and "w" is the width.

If you solve for "l":

P-2w=2l\\\\l=\frac{P-2w}{2}

In this case, you know that the following expression represents  the perimeter of the rectangle:

19m^2+2m-10

And the width of that rectanle is represented wih this expression:

m^2

Therefore, based on the explained above, you can conclude that the lenght  of that rectangle is given  by:

\frac{19m^2+2m-10-2(m^2)}{2}

Finally, simplifying the expression, you get:

=\frac{17m^2+2m-10}{2}=\frac{17}{2}m^2+m-5
