How do I find the answer

It’s a right angle so it’s 90 degrees :)

Answer:

x = 95 degrees

Step-by-step explanation:

First find the missing angle next to 142 (we will call it y)

y +142 = 180

subtract 142 from both sides

y = 38 degrees

then we know a triangle must have 180 degrees

47+38+x = 180

subtract 47 and 38 from 180

x = 95

hope this helps and makes sense :)

10 POINTS! PLEASE HELP!! The illustration shows a compact disc tray that holds five CDs. The radius of each compact disc is 9 cm.

What is the total area occupied by all five discs?

Answers

We can see that there are 5 CDs, each of radius 9 cm

Area occupied by 1 disc:

Area of a circle = πr²

Area of disc = π(9)²

Area of disc = 3.14 * 81 = 254 cm²

Area occupied by 5 discs:

Area occupied by 5 discs = Area occupied by 1 disc * 5

Area occupied by 5 discs = 254 * 5

Area occupied by 5 discs = 1270 cm²

not too sure about this, can anyone help?

Gerald has lots of land that are 12x square miles. He decides to purchase 4x more lots of land of the same size.(marking brainlist)

Answers

Answer:

48x square miles

Step-by-step explanation:

12x4 48

The total area that he has will be 48x² miles square.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

Gerald has lots of lands that are 12x square miles.

He decides to purchase 4x more lots of land of the same size.

Then the total land that he has will be given by the multiplication of the 12x and 4x.

⇒ 12x · 4x

⇒ 48x²

Then the total area that he has will be 48x² miles square.

Rhonda manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown in the table below. Which statement about the samples is true? Duck Pond Samples Sample 1 Sample 2 Mallard 19 Mallard 38 Wood Duck 3 Wood Duck 1 Green Wing Teal 10 Green Wing Teal 1 American Widgeon 8 American Widgeon 0 Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck. Rhonda should take a third sample and then use the two that are most representative since these samples vary quite a bit. Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond. Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.

Answers

Answer:

Step-by-step explanation:

Rhonda should continue taking samples of ducks until both samples have at least one of each type of duck.

What is migratory site?

A migratory site is a place where animals, especially birds, congregate during their seasonal migration.

Rhonda should keep collecting duck samples until both samples contain at least one of each type of duck.

Because neither Sample 1 nor Sample 2 contain at least one of each type of duck, Rhonda must collect additional samples until this criterion is met.

Rhonda would be incorrect to infer the average population of each type of duck in the pond based solely on the two existing samples because the samples are not representative of the entire population.

Thus, Rhonda should collect additional samples until both samples contain at least one of each type of duck, and then use all of the samples together to infer the population of each type of duck in the pond.

I need to calculate J and don’t know how please help me

Answers

K is opposite to 47 so k is also 47. I is opposite to 39 so I is also 39. You add all of those together making it 172. You then subtract it from 360.
So 47+47+39+39=172
360-172=188
188 is both j and opposite j so divide 188 by 2 and you get 94.
