A. Reflection across the x-axis, dilation using k-1/2
B. Rotation 80°, dilation using k=1/2

Answer:

8. Scalene 9. Isosceles

Step-by-step explanation:

8) Acute Scalene

9) Right Isosceles

Triangles can be classified in 3 ways based on their angles: acute, obtuse, and right. There are 3 ways to classify based on sides: scalene, isosceles, and equilateral.

Definitions

Acute - a triangle with 3 acute angles (angles under 90 degrees)

Obtuse - a triangle with 1 obtuse angle (angle greater than 90 degrees)

Right - a triangle with 1 right angle (90-degree angle)

Scalene - a triangle with sides of all different lengths

Isosceles - a triangle with 2 equal sides and angles

Equilateral - a triangle with 3 equal sides

Question 8

From the 2 angles we are given, we can tell that all of the angles are different. This must mean that the sides are also different. Since the sides are different, this must be a scalene triangle. Additionally, the missing angle is 100 degrees; thus, it must be an obtuse triangle.

Question 9

The marks on the 2 sides mean that these lines are equal. Therefore, it must be an isosceles triangle. One of the angles is marked with a box. This means that the angle is 90 degrees.  So, it is a right triangle.

Answer:height of the tree : 17.63 m

Step-by-step explanation:

Answer:

Option B and Option D

Step-by-step explanation:

B = 3*x = 3x, 3*15 = 45.

D=3* x + 15.

3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

Two or more expressions with an Equal sign is called as Equation.

We have to solve the equation  3x+45=180

Now isolate x on one side of the equation.

We can do this by subtracting 45 from both sides, giving us 3x=135, and then dividing both sides by 3 to get x=45.

Therefore, the equivalent equations are:

3x = 135

x + 15 = 60

Hence, 3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

Answer:

x = 15, y = 5

Step-by-step explanation:

total score of A = 6x

total score of B = 25*8 = 200

total score of C = 20y

(6x+200)/(x+25)=7.25

6x+200 = 7.25x+181.25

18.75 = 1.25x

x = 15

and

(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5

plug in x

(290+20y)/60 = 6.5

290 + 20y = 390

20y = 100

y = 5

Answer:

A) 300/6. B) Underestimate.

Step-by-step explanation:

50 is closer to 53.5 than 60 is so the closest aproximation would be 300/6

Step-by-step explanation:

w is the variable, you're trying to find what that variable could be. There are 5 boxes so you are trying to find "What minus 2, times 5, is equal to 40." OR (w-2)5=40. 8 times 5 is 40, but to compensate for the -2, add two to the 8 to get 10! hope this helps :)

Answer:

4

Step-by-step explanation:

There are 5 boxes.  Something times 5 is 40.  But,  w-2 has to equal 40.  Since 4 times 5 is 40, w is equal to 4.  4-2=2.  Replace w-2 with 4.  There are still 5 boxes.  So, multiply 4 x 5 and you get 40.

A=4000

B=560

C=32

Step-by-step explanation:

500*8=4000

70*8=560

8*4=32

Answer:

A = 4000

B = 560

C = 32

574 x 8 = 4592

Step-by-step explanation:

To find the area of A, we must multiply 500 by 8 because those are the dimensions.

500 x 8 = 4000

Therefore, A = 4000

To find the area of B, we must multiply 70 by 8.

70 x 8 = 560

Therefore, B = 560

To find the area of C, we must multiply 4 by 8.

4 x 8 = 32

Therefore, C = 32

To find the total area, we can add the area of A, B, and C together.

4000 + 560 + 32 = 4592

Step-by-step explanation:

The ordered pair (2,-5.2) is located in Quadrants IV. True

True, because Quadrants IV contains order pairs of the form  of (+,-)
