What is the formula for the volume of a trapezoidal prism?

Answers

Answer 1

Answer:

Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

4/6

Step-by-step explanation:

The probability of rolling a 6 is 1/6 as shown in the left section.

The probability of landing on tales is 1/2 as shown in the right section.

Becuase it is an or and not an and... you have to add them together.

1/6 + 1/2 = 1/6 + 3/6 = 4/6.

Therefore, the probability of rolling a 6 or landing on tails is 4/6.

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.

The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

How to convert from decimal to fraction?

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

For example:

[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]

(10 raised to power k = 1 followed by k zeroes)

How to add two fractions?

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of  [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we can see from the image that:

Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.

Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds

= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds

Thus, the weight is approx 3.55 pounds.

Converting it to fraction, we get:

[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.

Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

Chloe is driving on the freeway. She is 200 miles from Los Angeles. She drives at a constant speed of 55 miles per hour. Can Chloe get to Los Angeles in less than 3 1..2 hours?

Answers

Chloe is 200 miles from Los Angeles and she at a constant speed of 55 miles. You just do 200/55 and that’s how long Chloe drives in a hour.
No, it would take Chloe approximately 3.6 hours to reach LA.

200/55 = 3.64

A line passes through the points (-100,-9.5•10^3) and (300,3.05•10^4). Find the value of y when x =200. Write answer in scientific notation.Please help asap with details and steps on how to solve.

Answers

Answer:

2.05x10^4

Step-by-step explanation:

The equation of the line is y=100x+500, which can be found through the given points.

So, if x=200, plug that into the equation of the line. y=100(200)+500

y=20000+500

y=20500

In scientific notation, that is 2.05x10^4

Answers

Answer:

the vertex is at (4, -14)

Step-by-step explanation:

Review "quadratic equations."  These have three terms, and the highest power of x is x^2.  We need to identify the coefficients of the x^2, x and x^0 terms to get info needed to identify the axis of symmetry.

Given f(x) = x^2 - 8x + 2, we see that these coefficients are 1, -8 and 2.

                                                                            b

The formula for the axis of symmetry is x  = - ------

                                                                             2a

which here is x = -(-8)/[2*1], or x = 8/2  or x = 4:  the axis of symmetry.

To find the y-coordinate of the vertex, evaluate the function at x = 4:

f(4) = 4^2 - 8(4) + 2 = 16 - 32 + 2, or f(4) = -14.

Thus, the vertex is at (4, -14).  The graph is that of a parabola that opens up, and the parabola is symmetric about the vertical line x = 4.

Split there firgue into shapes you know

there is a rectangle and a Trapezoid

A = bh

A = 1/2×8(26)

A = 1/2(208)

A = 104cm

Add them together

Step-by-step explanation:

An outlier is a point of data in a data set that is far out from the median in the data set. In this case, almost all of the data points are from 0 minutes of exercise to 60 minutes, except for two that are more than double that.

It could "skew" the data, as if you were to calculate the mean (average), it would be shifted slightly higher by these two outliers.
