In The Diagram, DEC Is Aof ABC Across Line M.A. RotationB. Glide ReflectionC. TranslationD. Reflection

Answers

Answer 1

Step-by-step explanation:

This is a reflection. A reflection is a transformation involving two shapes looking the same by "bouncing it off a line without coming back.( meaning a reflection goes some where else not to it original poistion.)

Others reason why Why?

Line m is perpendicular to Line c.

B and E are equidistant from c that BC=CE.

Why the others are wrong.

While you could rotate this triangle 180 degrees, the transformation occurs about a line not a point. So using a rotation is wrong.

A translation doesnt occur about a line.

A guide reflection doesnt work since the transformations are already mapped correctly if you do the reflection. It doesnt need a translation.

Julie wants to attend a two-year college that has an annual tuition of $8,600. Julie earned a grant of $1,600 for each year and has saved $5,980 for college. How much more does she need to pay the tuition for both years?

Answers

Answer: $8,020

Steps:
$8,600 * 2yrs = $17,200

$1,600 * 2yrs = $3200

$3200 + $5980 = $9180

$17,200 - $9,180 = $8,020

Answers

Answer:

7 1/2 quart of paint

Step-by-step explanation:

To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *

The above question is solved as:

3 1/4 quart + 1 2/4 quart + 2 3/4 quart

Lowest common denominator = 4

3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)

= 6 + ( 1 + 2 + 3/4)

=( 6 + 6/4) quart

= 6 + 1 2/4 quart

= 7 2/4 quart of paint

= 7 1/2 quart of paint

Therefore, Johan made 7 1/2 quart of paint

Step-by-step explanation:

The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...

  3x +12 < 0

  x +4 < 0

  x < -4 . . . . . makes the absolute value function change its argument's sign

Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.

Answers

Answer:

45 cm

Step-by-step explanation:

Area of a triangle:

A = 1/2bh

b = 3 + 2 = 5

A = 1/2(5)(6)

A = 15

Area of a rectangle:

A = bh

A = 12*2.5

A = 30

Combined:

30 + 15 = 45

The sailboat has 2 right angle triangles and a rectangle

First lets find the area of the rectangle then each one of the triangles

Area of rectangle = Length × Height

Area of rectangle = 12 × 2.5

Area of rectangle = 30 cm²

Now lets find the area of triangle on the right,

Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]

Area of triangle = 6 × 3 × [tex]\frac{1}{2}[/tex]

Area of triangle = 18 × [tex]\frac{1}{2}[/tex]

Area of triangle = [tex]\frac{18}{2}[/tex]

Area of triangle = 9 cm²

Now lets find the area of the triangle on the left,

Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]

Area of triangle = 6 × 2 × [tex]\frac{1}{2}[/tex]

Area of triangle = 12 × [tex]\frac{1}{2}[/tex]

Area of triangle = [tex]\frac{12}{2}[/tex]

Area of triangle = 6 cm²

Now lets find the total area of the sailboat,

Total area = Area of rectangle + Area of triangle on the right + Area of triangle on the right

Total area = 30 + 9 + 6

Total area = 39 + 6

Total area = 65 cm²

Therefore the total area of the sailboat is 65 cm²

The measure of an angle is 39°. What is the measure of its complementary angle?

Answers

Answer:

51 degrees

Step-by-step explanation:

Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).

90 - 39 = 51

Answer:

51°

Step-by-step explanation:

Complementary angles add to 90°.

If one of them is 39°, then the other is:

90° - 39° = 51°

Five less than the product of seven and a number x:

7x - 5

nine times a number y:  9·y = 9y

The difference of nine times a number y and eighteen:

9y - 18

3)

Half a number n increased by four times the number:

HELP!!! Will give brainliest:) What shapes have all sides that are congruent?

Answers

Answer:

A square has all sides congruent. SIDE A, B, C and D would be congruent in size to one another, and the angles would also be equal to one another. However, most any polygon can be drawn with all sides and angles equal. For instance, an equilateral triangle has all sides and all angles equal, and that is the definition of a polygon. Polygons with more sides are described as "regular" e.g., a stop sign or an equilateral octagon is also a shape that has all sides congruent. A rectangle, however, would not, since only two sides would be congruent to one another.
