Which sequence of transformations on △ABC will result in a figure that is congruent to △ABC?

Answers

Answer: A.) c is -1 -2 b is -4 -2 a is -3 -3

Step-by-step explanation: sry but thats all i know i hoped i helped a lil bit :)

Any sequence of transformations that include a “dilation” changes the overall size of the shape, so your answer would actually be “B” since it’s only being rotated and reflected. In other words, the location of the shape is the only thing being changed.

Hannah has 19 more bouncy balls than Stefan. Stefan has b bouncy balls. Write an expression that shows how many bouncy balls Hannah has.

Answers

Answer:19+ b

Step-by-step explanation:

Answer:

B + 19

Step-by-step explanation:

B is an unknown number. *

Example.

If Stefan has 1 bouncy ball, Hannah would have 20.

Formula.

Stephan's Amount + 19 = Hannah's Amount

Solving Your Problem.

We will do the same thing except replacing "1" with "b".

b = Stefan's Amount

b + 19 = Hannah's Amount

We are just adding 19 to his.

Note: In Algebra, we use lowercase variables usually...just a side note.

I hope I helped you solving this problem, and sorry if I have bad english. I am learning every day thank you! :)

We need to find the triangular pyramid formula which is 1/3*B*H
The base is always the bottom or foundation. To find this we need the area of the triangle at the bottom.
It is 8*6/2 or base times height divided by 2
We would get 24
This is our B value. Now height is 4 in they give us this.
Plug it in 24*4/3
We get 32 inches

Read another paragraph and graphic from the text “Overfishing the Oceans.” Then answer the question.
Overfishing is a problem that affects a whole ecosystem. A healthy ocean has a balance of different species. One problem with overfishing is that it takes away many of the top predator fish and disrupts this balance. Overfishing can also disrupt the marine ecosystem in other ways.

Based on the information in the paragraph and graphic, what might be a result of a decrease in tuna populations?
A. Sharks may have difficulty finding food.
B. A rise in squid and mackerel populations.
C. The balance in the food web would be disrupted.
D. All of the above are potential results of a decrease in tuna populations.

Answers

D- all of the above because sharks eat tuna, tuna eats mackerel and squid meaning if there’s nothing to eat them the population will just grow. And ofc the balance of the food web will be wack so all of the above

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

Luke and Pedro work for Crown Carpentry. On Thursday, they each hung the same amount of wooden trim, but Pedro finished first. On Friday, they will work for the same amount of time hanging trim in a new movie theater. Will Pedro likely hang more trim or less trim than Luke?

please help

Answers

I think he’ll hang more because on Thursday, they both hung the same amount but Pedro finished first meaning he can hang trim faster than Luke. So if they both worked for the same amounth of time, for example if Luke worked for as much time as it took Pedro to hang trim on Thurday, Luke wouldn’t have been finished. I hope that makes sense!
