The transformation is better described by:  Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime

In mathematics, transformation is manipulating a figure on a plane or coordinate system.

In this case the manipulation involves reflection and scaling to a factor between 0 and 1

scaling to factor 0 means the triangle disappeared

scaling to factor 1 means the triangle remained same size

factors between 0 and 1 means reduction of size.

since the transformation did not rotate the triangle it makes the first option the correct answer

Answer: C) Yes, Alternate Exterior Angles Converse

The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".

this question makes no sense because it says he fills boxes that hold 9 muffins but how many large boxes does he have that's the real question

but what im thinking is if he fills large boxes with muffins and the large boxes hold 9 then if u divide 88/9 u get 9.78 so

Answer:

303 cents.

Step-by-step explanation:

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer

We know that, dollar is equal to 100 cents

2 dollars = 200 cents

It means, Daniel found 9 cents in his backpack, 89 cents in the couch, and 200 cents and 5 cents in the drawer.

Price = 9+89+200+5

= 303 cents

Hence, Daniel found 303 cents.

Step-by-step explanation: divide 11 by 24.

Answer:

The first choice.

Step-by-step explanation:

The volume must be about 226.19 in^3.

Volume of a cylinder = area of base * height4

= πr^2h  = 226.19

r^2 = 226.19 / πh.

Consider the first of the choices:-

When h = 8 , r^2 = 226.19 /8π = 8.9998

So r = 3.00  to nearest hundredth.

Answer: 75%

Step-by-step explanation:

75% of 8 is 6.

8 was decreased by 6 to get 2.

8 was decreased by 75% of its initial value to get 2.

Hope this helped!

Answer:

75%.

Step-by-step explanation:

8 - 100%

2 - x

[tex]\dfrac{8}{100 \%}=\dfrac{2}{x} \\\\x=\dfrac{2 \cdot 100 \%}{8} =25 \%[/tex]

100% - 25% = 75% - the percent decrease.

Answer:

answer is 10/9

:-)))☺️☺️

I hope it helps you

Answer: 1 and 1/9

Step-by-step explanation: Here, we have 5/6 ÷ 3/4.

Dividing by a fraction is the same as multiplying by its reciprocal.

In other words, we can change the division

sign to multiplication and flip the second fraction.

So here, 5/6 ÷ 3/4 can be rewritten as 5/6 × 4/3.

Now we're simply multiplying fractions so we multiply across the

numerators and multiply across the denominators.

So we have 5 × 4 which is 20 and 6 × 3 which is 18.

Notice that 20/18 is not in lowest terms so we divide the

numerator and the denominator of 20/18 by 2 to get 10/9.

If you would like, you can change this to the mixed number 1 and 1/9

by simply dividing 9 into 10 and putting the remainder over the denominator.

Answer:

HI! I think the answer is 4.

Answer:

4/5 = 4 x 1/5

Step-by-step explanation:

Since we can write 4 as 4/1, that means 4 is the answer. This is because you multiply the top numbers and the bottom numbers, 4x1 is 4, and 1x5 is 5, so that means the answer is 4 since that problem got us 4/5.

The sum of two opposite interior angles equals an exterior angle

50+?=115

?=115-50=65°

Answer:

60 degrees

Step-by-step explanation:

angles on a straight line add up to 180 degrees.

so do 180-115=60

because its an equilateral triangle, you can check whether it adds up to 180

60+60+50=180

Answer:

20ft

Step-by-step explanation:

The height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Consider the diagram below.

We've got:

The wall is usually perpendicular to ground, therefore making 90° angle with it. Thus, ABC is a right angled triangle.

Using Pythagoras theorem in it, we get:

[tex]|AC|^2 = |AB|^2 + |BC|^2\\\\30^2 = |AB|^2 + 10^2\\|AB|^2 = 900 - 100\\\\|AB|^2 = 800\\\\\text{Taking sq. root of both the sides}\\\\|AB| = \sqrt{800} = \sqrt{ (\pm 20\sqrt{2})^2}\\\\|AB| = \pm 20\sqrt{2} \: \rm ft[/tex]

But as length cannot be a negative quantity, so we get:

[tex]|AB| = 20\sqrt{2} \: \rm ft[/tex]

Thus, the height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.
