Answer:

  B. △ABC: equilateral; △EFG: equilateral

  C. △ABC: isosceles; △EFG: isosceles

Step-by-step explanation:

A triangle in which all angles are equal is an equilateral triangle. Any equilateral triangle is also an isosceles triangle (two sides/angles have the same measure).

The two triangles are both equilateral (B) and isosceles (C).

__

Additional comment

The angles of an equilateral triangle are all 60°. The sides are all the same length. A right triangle will have an angle of 90°, so the given triangles cannot be right triangles. A scalene triangle has all angles/sides different measures, so the given triangles cannot be scalene.

Answer:180

Step-by-step explanation:

Hue is arranging chairs. She can form 2 rows of a given length with 5 chairs left over, or 6 rows of that

same length if she gets 11 more chairs. Complete the equation and solve it to find how many chairs are in

that row length. In your equation, use the variable x to represent the number of chairs in each row.

The equation is

There are

chairs in each row.

Let, no. of chairs in each row = x

There are 2 rows of given length with 5 chairs left over.

6 rows of the same length if given 11 more chairs 2x+5 will be equal to 6x

If 11 chairs are added to 2x+5 because 6x has 11 more chairs than 2x+5

=> 2x+5+11 = 6x

=> 2x+16 = 6x

=> 4x = 16

=> x = 16/4

=> x = 4

x=4 chairs in each row with 5 left over makes 2*4+5 = 13 chairs

add 11 chairs to 13 chairs and you get 24 chairs which is 6 rows of 4 chairs in each row.

The correct statement is that the range of the data is 9

The formula for calculating the range of data is expressed as:

Range = Highest value - Lowest value

From the given data

Substituting into the formula

Range = 20 - 11

Range = 9

Hence the correct statement is that the range of the data is 9

From the fraction solved, the distance that the rabbit should be behind the turtle will be 400 meters.

From the information, it was stated that a rabbit and a turtle run 100 meters and that when the rabbit finished, the turtle was behind by 80 meters. Therefore, the distance covered by the turtle will be:

= 100 - 80

= 20 meters

Therefore, the fraction of their distance will be:

= 20/100 = 1/5

Therefore, the number of meters behind the turtle that the rabbit should start will be:

= 80 × 5

= 400 meters.

Answer:

Each notebook costs $1.25

Step-by-step explanation:

We'd have to add back the $6.00 coupon to the original price which would now be $11.25.

After getting the original price we now have to divide the price by 9, because of the 9 notebooks you've purchased.

Therefore, the price of $11.25 divided by the 9 notebooks would cost 1.25 each.

Step-by-step explanation:

we just do the multiplications that squaring is :

(x² + y²)² = (x² + y²)(x² + y²) =

= x⁴ + x²y² + x²y² + y⁴ = x⁴ + 2x²y² + y⁴

(x² - y²)² + (2xy)² = (x² - y²)(x² - y²) + 2xy×2xy =

= x⁴ - x²y² - x²y² + y⁴ + 4x²y² =

= x⁴ - 2x²y² + y⁴ + 4x²y² =

= x⁴ + 2x²y² + y⁴

as you can see, both results are the same.

therefore, the original equation is a true identity.

Answer:

10400km

Step-by-step explanation:

We know that the scale on a map is 1cm for every 400km. So to find the actual distance for 26cm on the map, we take 26 multiplied by 400km. This gives 10400km.

Both Diego and Mai are interpreting the said graphs (please see attached) in terms of which are Negative, Positive, or neutral.

When you want to interpret a linear equation in relation to a graph, it is important to note that two factors are critical:

If the slope of the line rises from left to right, it is Positive; If it falls from left to right, it is negative, and if it remains on the same line across, but above the y-axis, then it is constant but above zero.

Therefore, in the order they have been arranged, the first graph is negative because its last value falls below the y axis, the second is above the y-axis but constant at a level above zero, while the third has its values increasing from left to right above the y-axis.

Step-by-step explanation:

1. k = 32

k + 19 = 51

32 + 19 = 51

51 = 51

correct, so, k=32 is a valid solution.

2. x = 43

16 = x - 27

16 = 43 - 27

16 = 16

correct, so, x = 43 is a valid solution.

3. m = 9

28 - m = 17

28 - 9 = 17

19 = 17

wrong. so, m = 9 is NOT a valid solution.

4. y = 8

y + 19 = 27

8 + 19 = 27

27 = 27

correct, so, y = 8 is a valid solution.

5. p = 22

19 = p + 3

19 = 22 + 3

19 = 25

wrong. so, p = 22 is NOT a valid solution.

6. r = 11

4 + r = 15

4 + 11 = 15

15 = 15

correct, so, r = 11 is a valid solution.

7.

a - 8 = 9 adding 8 to both sides

a = 17

8.

v + 13 = 15 subtracting 13 from both sides

v = 2

9.

16 = n - 24 adding 24 to both sides

40 = n or n = 40, of course

10.

c - 9 = 16 adding 9 to both sides

c = 25

11.

11 + k = 18 subtracting 11 from both sides

k = 7

12.

15 = w - 7 adding 7 to both sides

22 = w or w = 22, of course
