Find the volume of the triangular prism in the picture shown. Round your answer to the
Olenka [21]

Given:

A figure of a triangular prism.

Height of triangular base = 9\dfrac{2}{3} yd

Base of triangular base = 4 yd

Height of prism = 4 yd.

To find:

The volume of the triangular prism.

Solution:

Volume of a triangular prism is:

V=Bh              ...(i)

Where, B is the area of triangular base and h is the height of the prism.

Area of triangular base is:

B=\dfrac{1}{2}\times base\times height

B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}

B=2\times \dfrac{29}{3}

B=\dfrac{58}{3}

Putting B=\dfrac{58}{3} and h=4 in (i), we get

V=\dfrac{58}{3}\times 4

V=\dfrac{232}{3}

V=77.33...

V\approx 77.3

The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo
Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = \frac{1}{60} hours

Therefore, number of words she can type = \frac{90}{\frac{1}{60}}

                                                                      = 90×60

                                                                      = 5400 words per hour

If she types 2.6\times 10^5 words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= 5400\times x

Therefore, 5400\times x =2.6\times 10^5

5400x=260000

x=\frac{260000}{5400}

x=48.15 hours

Therefore, Dana types 2.6\times 10^5 words in 48.15 hours.

Pls work out and give detail. Use the slope formula to determine the slope of each line.
kolbaska11 [484]

Answer:

m=0

Step-by-step explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

(x_1,y_1) = (-4,1)

and

(x_2,y_2) = (3,1)

The slope m is then calculated using:

m = \frac{y_2- y_1}{x_2 - x_1}

Substitute values for the x's and y's

m = \frac{1-1}{3 - (-4)}

m = \frac{1-1}{3 +4}

m = \frac{0}{7}

m=0

<em>Hence, the slope is 0</em>
