Select the correct answer. Quadrilateral ABCD is inscribed in circle P as shown. Which statement is necessarily true? A. m∠A + m∠B = m∠C + m∠D B. m∠A + m∠C = m∠B + m∠D C. m∠A + m∠D = m∠B + m∠C D. m∠A + m∠B = 2(m∠C + m∠D)

Answers

Answer 1

Answer:

[tex]\angle A + \angle C = \angle B + \angle D[/tex]

Step-by-step explanation:

See attachment for cyclic quadrilateral

From the attachment:

A opposites C and B opposites D

In a cyclic quadrilateral:

Opposite angles adds up to 180

So:

[tex]\angle A + \angle C = 180[/tex]

[tex]\angle B + \angle D = 180[/tex]

[tex]180=180[/tex]

So:

[tex]\angle A + \angle C = \angle B + \angle D[/tex]

As division is the inverse of multiplication, the rules for division are the same as the rules for multiplication. So when multiplying and dividing positive and negative numbers remember this: If the signs are the same the answer is positive, if the signs are different the answer is negative.

An experiment to test the effectiveness of regular treatments with fluoride varnish to reduce tooth decay involved 36 volunteers who had half of their teeth (the right side or left side, determined by a coin flip) painted with a fluoride varnish every six month for 5 years. At the end of the treatments, the number of new cavities during the treatment period was compared on treatment (fluoride varnish) side versus the control (no fluoride varnish) side. The appropriate statistical test for analyzing the results of this experiment is

Answers

Answer:

One-sample t-test on paired data.

Step-by-step explanation:

Here, two different measures or reading were obtained for the two treatment (fluoride vanish) and the control (no fluoride vanish). However, this two measurement were obtained from each of the observations or subjects, hence why it is called one sample t-test on paired data. This would allow the effectiveness of the floiride vanish treatment on each the subjects teeth as we'll have two different data (fluoride vanish treatment) and control treatment on each the subjects employed for the study.

A cedar chest is a shaped like a rectangular prism. The cedar chest is 2 feet tall, 4 feet wide, and 2 feet deep What is the surface area of the cedar chest? Enter your answer in the box

Answers

Answer:

40 ft^2

Step-by-step explanation:

lateral surface area -Slat = 24 ft^2

top surface area-Stop = 8 ft^2

bottom surface area-Sbot = ft m^2

24+8+8= 40

total surface area-Stot = 40 ft^2

The surface area of a rectangular prism or cedar chest of 2 feet tall, 4 feet wide, and 2 feet deep is 40ft sq.

The length of a rectangular prism is 2 feet.

The width of a rectangular prism is 4 feet.

The height of a rectangular prism is 2 feet.

we need to find the surface area of a rectangular prism.

What is a rectangular prism?

A rectangular prism is a 3-dimensional representation, that has six rectangular faces two at the top and bottom and four are lateral faces. A rectangular prism is also known as a cuboid.

The surface area of a rectangular prism = 2(lb + bh + lh)

So, the surface area of a rectangular prism = 2(lb + bh + lh)

[tex]=2(2\times4+4\times2+2\times2)\\=2(8+8+4)\\=40[/tex]

Hence, the surface area of a rectangular prism or cedar chest is 40ft sq.

if there already is 9200 then that would be added to 80c and, when solved, would tell you how many 80kg containers can be loaded
