Answer:

The answer should be around 1,149663 (Rounded off to the nearest whole number. Also if a population has a remainer you usually add it as 1. This is because these are people)

Step-by-step explanation:

First step involves listing the formulas being used:

600,000= population, 0.03= growth rate 22years= period

Therefore, we take the 600,000 and multiply by 1+0.03 ^22(to the power of 22 or period)

So, 600,000(1+0.03)^22

=1,149662.045 /1,149663

Hope this helps!

Answer:triangles always equal 180 so subtract the variable inside the triangle.

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

A^2+b^2=c^2

8^2+15^2=20^2

64+225=400

289=400

289 does not equal 400 so it is not a right triangle

Answer:

c

Step-by-step explanation:

Answer:

9.8 is the correct answer

The variable x is the hypotenuse, and the value of x in the right triangle is 24.8

The complete question is a right triangle, where x is the hypotenuse.

So, the equation of x is:

[tex]x^2 = 19^2 + 16^2[/tex]

Evaluate the sum of exponents

[tex]x^2 = 617[/tex]

Take the square root of both sides

x = 24.8

Hence, the value of x is 24.8

Answer:

two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

(instead of translations/rotations we could write transformations, but there are transformations that also change the size of the figure, so I think that writing translations/rotations is more precise)

Step-by-step explanation:

Two figures are congruent if they have the same shape and size.

So for example, if we have one triangle, and we reflect that triangle along some line, those bot images will have the same shape and size (but maybe different orientations) so the triangles are still congruent.

Also, we could translate the image, or simply rotate it along some point, and the resulting image will be congruent to the initial image.

Then two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

The composition that maps one polygon to the other polygon to make both congruent is called; Similarity transformation.

Now, we are told that there has to be a composition that will map one polygon to another one. This means that the two polygons must have the same shape after transformation.

Answer: See explanation

Step-by-step explanation:

Your question isn't well written. Let's reframe it and solve.

Michael has 938cups of glue. He wants to put 11 cups into each smaller container. How many smaller containers can he fill?

To solve this question, we have to divide the total cups of glue that Michael has by the number of cups that he wants to put in each container. This will then be:

= 938 / 11

= 85 3/11

Therefore, he can fill 85 containers.

To solve the question in case you've different numbers, just follow the steps above and you'll get it.

Answer:91

Step-by-step explanation:

Take the area of the large square - 10*10 =100

Then subtract the area of the white square - 3*3 = 9

So 100-9 =91 units^2

Answer:

91 [tex]units^2[/tex]

Step-by-step explanation:

To do this you have to find the area of the total square using A=bh

So, A= (10)(10)

A=100

then find the area of the unshaded square using the same formula

A=(3)(3)

A=9

Then, subtract 100-9=91

So, your answer for the shaded square is 91 [tex]units^2[/tex]

Answer:

x = 21

Step-by-step explanation:

If lines AB and CD are parallel, then we can assume that m<5 and m<6 are supplementary that is the sum of both angles is 180degrees

Hence;

3x - 31 + 148 = 180

3x + 117 = 180

Subtract 117 from both sides

3x+117-117 = 180 - 117

3x = 180 - 117

3x = 63

x = 63/3

x = 21

Hence the value of x will be 21 if both angles are supplementary
