The length of a rectangular portrait is 1.5 times the width. The perimeter is 10 feet.

disa [49]

In order to solve the problem above, represent the width by x. With this, the length of the rectangular portrait is 1.5x. The perimeter of the rectangle is two times the sum of the length and width. This translates to,

2 (1.5x + x) = 10 ft, x = 2 ft.

Thus, the length of the rectangular portrait is 3 ft.

tensa zangetsu [6.8K]

So I’m thinking of this as two triangles. So I would do 16x8/2 which equals 64 and 10x6/2 which equals 30. So my guess is that the area is 94in^2. Hope this helps you out!

Korolek [52]

Relative frequency = event/sample space
50/14 = 0.28

Expected probability = relative frequency*event
0.28*7500 = 2100
About 2100 trout is expected to be in the lake.

The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 6 mm. What is the

Kryger [21]

Answer: $2,034.72\ mm^3$

Step-by-step explanation:

The missing part is: "A cylinder and 2 half spheres. All have a radius of 6 millimeters. The cylinder has a height of 10 millimeters."

You need to use the following formulas to solve the exercise:

1. The volume of a cylinder can be calculated with:

$V_{c}=\pi r^2h$

Where "r" is the radius and "h" is the height.

2. The volume of a sphere can be calculated with:

$V_{s}=\frac{4}{3}\pi r^3$ Where "r" is the radius.

In this case you know that the cylinder and the sphere have a radius of 6 millimeters and the height of cylinder is 10 millimeters. Then, you can substitute values into each formula in order to find the volumes:

$Vc=(3.14)(6\ mm)^2(10\ mm)\\\\Vc=1,130.4\ mm^3\\\\\\Vs=\frac{4}{3}(3.14)(6\ mm)^3\\\\Vs=904.32\ mm^3$

Adding them, you get that the volume of the composite figure is:

$V_{CF}=1,130.4\ mm^3+904.32\ mm^3\\\\V_{CF}=2,034.72\ mm^3$
