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

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

Maurinko [17]

Answer: 792

Step-by-step explanation:

From what I got it should be 792 because it is asking for doubles, triples, and home runs all together at the same amount that he got on his first year.

It says after 12 years

Doubles 47 times 12 years = 564

Triples 4 times 12 years = 48

and

Home runs 15 times 12 years = 180

564 + 48 = 612

612 + 180 = 792

Cynthia Besch wants to buy a rug for a room that is 1919 ft wide and 2727 ft long. She wants to leave a uniform strip of floor a

yulyashka [42]

Answer:

The dimension of the rug would be 17 ft × 9 ft.

Step-by-step explanation:

Given

length of the room = 27 ft.

width of the room = 19 ft.

suppose, she leaves a uniform strip of x ft. around the rug.

So,

The length of rug = (27-2x)ft.

Width of rug= (19-2x)ft.

∴ Area of the rug= length×width

$= (27-2x)(19-2x)$

$= 513-54x-38x+4x^2$

$= 513-92x+4x^2$

According to the question,

$513-92x+4x^2=153$

$513-92x+4x^2-153=0$ ( subtract 153 both sides)

$4x^2-92x+360=0$

$4(x^2-23x+90)=0$

$x^2-23x+90=0$

$x^2-(18+5)x+90=0$ ( Middle term splitting)

$x^2-18x-5x+90=0$

$x(x-18)-5(x-18)=0$

$(x-5)(x-18)=0$

$x-5=0$ or $x-18=0$ ( zero product property)

$x=5$ or $x=18$

if x=18, dimension would be negative ( Not possible)

Thus, x= 5

Hence,

length of rug= 27-10=17 ft.

width of rug= 19-10=9 ft.
