Which polygons are congruent?

Answers

Answer 1

Answer: Two polygons are congruent if they are the same size and shape - that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see the corresponding parts of the congruent figure on the right.

Factor completely and then place the factors in the proper location on the grid.a 2 - a - 20

Answers

Answer:

The correct answer is (a+4)(a-5)

Step-by-step explanation:

We have the polynomial $a^2-a-20$

For the polynomials of the form $ax^2+bx+c$ we have to rewrite the middle term as a sum of two terms whose product is, in this case, a.c=-20 and whose sum is b=(-1).

$a^2-a-20=\na^2+(-5+4)(a)-20=\n=a^2-5a+4a-20$

Because b=(-5)+4=(-1) and a.c=(-5).4=(-20)

Now we have to factor by grouping:

$a^2-5a+4a-20=\n(a^2+4a)-(5a+20)=\na(a+4)-5(a+4)=\n=(a-5)(a+4)$

Then, the correct answer is (a+4)(a-5)

The fully factored form of this expression would be
(A-5)(A+4).

A skydiver is falling 176 feet per second. how many feet per minute is he falling?

Answers

So you would have to times 176 by 60 ,because of 60 seconds in a minute, and that would be 10,560 ft per minute

60 seconds in a minute so 179 times 60 equals 727 fpm

Two friends leave school at the same time, Sarah is heading due north and Beth is heading due east. One hour later they are 10 miles apart. If Sarah had traveled 8 miles from the school, how many miles had Beth traveled?6 miles
10 miles
8 miles
4 miles

Answers

If you picture this scene in your head, you will get a simple 3x4x5 right triangle. 4 times 2 is 8, 5 times 2 is 10, so Sarah should, by now, have traveled 3 times 2 miles.
Final answer: Sarah has traveled 6 miles after an hour.
Hope this helped! :)

Helping tip: The reason it is not 4 is because they are not traveling west and east away from each other. They are traveling north and east, so they are moving in two directions to form a right triangle, and the hypotenuse would be 10 (miles). The side, or distance, that Beth has traveled is 8. So as this is a typical variation of a 3x4x5 triangle, Sarah will have traveled 6 miles.

wouldn't it actually be 2 miles but since its not listed I would say 4 because if there 10 miles apart and Sarah is 8miles from the school were they both started then 10-8=2. or you can take the two and divide it by 8 and get 4

the base of a jewelry box is a square with a side length of 5 1/2 inches. the box is 2 inches high. what is the volume of the box?

Answers

The volume of the jewelrybox is 60 1/2 cubic inches.

The area of a square with a side length of 5 1/2 inches can be found by multiplying the length of one side by itself, giving:

Area = (5 1/2) × (5 1/2) = 30 1/4 square inches

The height of the box is 2 inches.

Therefore, the volume of the jewelry box can be found by multiplying the area of the base by the height of the box, giving:

Volume = Area x Height = (30 1/4) × 2 = 60 1/2 cubic inches

Thus, the volume of the jewelrybox is 60 1/2 cubic inches.

If a sphere’s volume is doubled, what is the corresponding change in its radius?

Answers

The answer is the radius is increased ∛2 (≈ 1.26) times.

The sphere's volume formula is:
V = 4/3 π r³
where:
V - the sphere's volume,
r - radius of the sphere.

If sphere's volume is doubled, we have:
V₁ = 4/3 π r₁³
We need to know what is the ratio of r₁ and r.

V₁ = 2 × V = 2 × 4/3 π r³
⇒ 2 × 4/3 π r³ = 4/3 π r₁³
We can remove the same parts of the left and right sides of the equation:
2 × r³ = r₁³
r₁ = ∛(2 × r³)
r₁ = ∛2 × ∛r³
r₁ =∛2 × r
r₁ ≈ 1.26 r
Or: r₁/r = 1.26

Therefore, the radius is increased ∛2 (≈ 1.26) times.
