A suit case is a rectangular prism whose dimensions are 1 and 1/2 feet by 1 and 3/4 feet by 2 and 1/2 feet. Fond the volume of t

Andre45 [30]

Answer:

$\frac{105}{16} ft^3$

Step-by-step explanation:

The suitcase is in the shape of a rectangular prism and we need to find the volume.

The volume of a rectangular prism is given as:

V = L * B * H

where L = length

B = breadth

H = height

The dimensions of the suitcase are $1\frac{1}{2} ft$ by $1 \frac{3}{4} ft$ by $2 \frac{1}{2} ft$

Therefore, the volume of the suitcase is:

$V = 1\frac{1}{2} * 1 \frac{3}{4} * 2 \frac{1}{2} \\\\V = \frac{3}{2} *\frac{7}{4} *\frac{5}{2} \\\\V = \frac{105}{16} ft^3$

The volume of the suitcase is $\frac{105}{16} ft^3$

Answer:

A triangular prism

Step-by-step explanation:

The 3 rectangles represent 3 sides of the prism. Imagine folding on the line, and connecting the left side of the first rectangle to the right side of the third rectangle. It will make a triangle that has depth.

Looking that the top and bottom triangles attached to the third rectangle shows us that the top and bottom of this shape are triangles, which matches the three sides.

What we have is a 3D triangle, which we call a triangular prism

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) os located at (-2,1). What is the distance fr

Sergio039 [100]

Answer:

The distance from B to B' is 5 units

Step-by-step explanation:

The complete question is

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) and point A' is located at (-2,1). What is the distance from B to B'?

we know that

In a translation the figure maintains its dimensions and internal angles

AA'=BB'=CC'=DD'

The distance BB' is the same that the distance AA'

Find the distance AA'

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

A(1,5),A'(-2,1)

substitute in the formula

$AA'=\sqrt{(1-5)^{2}+(-2-1)^{2}}$

$AA'=\sqrt{(-4)^{2}+(-3)^{2}}$

$AA'=\sqrt{25}$

$AA'=5\ units$

therefore

The distance from B to B' is 5 units

I need help ASAP!!Explain the answer

nordsb [41]

Answer:

volume=pi times r^2 height÷3.

r is the radius, or in this case 4yd. height is 10yd. pi is 3.14

Here are the steps:

3.14r^2 height÷3

3.14×4^2 10÷3

=167.55

final answer rounded to the nearest tenth: 167.6

I apologize for getting the math wrong the first time. My formula was correct, but I needed to double check my calculations. I'm certain this is the right answer.

How do I find the area of a triangle with a base of 3 and height of 6

Schach [20]

You can multiply 3 and 6 together then divide the product by 2
(6*3)/2=18/2=9
