Using diagonals from a common vertex, the maximum number of triangles that will be formed is 5 triangles.

The given polygon is irregular heptagon (7 unequal sides).

The given polygon is irregular and the maximum number of triangles that will be Formed is explained as follows;

Alternatively, we can use the following formula;

number of triangles formed = 7 - 2 = 5 triangles

Thus, using diagonals from a common vertex, the maximum number of triangles that will be formed is 5 triangles.

Answer:

A, C, and E.

Step-by-step explanation:

I looked up what half a mile was in meters, yards, and feet, and it told me these were the right answers.

The equivalent to 1/2 mile:

A. 804.5 meters

C. 880 yards

E. 2,640 feet

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

To convert 1/2 mile to other units of distance:

1/2 mile = 0.5 mile

A. 804.5 meters ≈ 0.5 miles

(1 mile ≈ 1609 meters, so 0.5 miles ≈ 804.5 meters)

B. 845 meters ≈ 0.524 miles (1 mile ≈ 1609 meters, so 845 meters ≈ 0.524 miles)

C. 880 yards ≈ 0.5 mile (1 mile = 1760 yards, so 0.5 mile = 880 yards)

D. 3,520 yards ≈ 2 miles (1 mile = 1760 yards, so 2 miles = 3520 yards)

E. 2,640 feet ≈ 0.5 mile (1 mile = 5280 feet, so 0.5 mile = 2640 feet)

F. 10,560 feet ≈ 2 miles (1 mile = 5280 feet, so 2 miles = 10560 feet)

Therefore, the distances that are equivalent to 1/2 mile are A, C, E.

We have to find which trinomial has:

1) two terms that are the perfect square of two numbers

2) a terms that is the double product of the two numbers

the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2

Options C and D are traps because the square of a number can’t be negative

Answer:  M=2.4R

Step-by-step explanation:

If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...

24/10=2.4

so now we can set up our equation...

M=2.4R

this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.

Answer:

AE = 9 units

Step-by-step explanation:

Based on the centroid theorem:

AX = ⅔ of AE

Given that AX = 6 units, where X is the centroid of ∆ABC, therefore:

6 = ⅔ of AE

6 = ⅔(AE)

Multiply both sides by 3

6*3 = ⅔(AE)*3

18 = 2(AE)

Divide both sides by 2

18/2 = AE

9 = AE

AE = 9 units

Answer:

x = 33

Step-by-step explanation:

cross-multiply:

x-9 = 2(12)

x-9 = 24

x = 33

Answer:

The answer is 33.

Step-by-step explanation:

1) Multiply both sides by 2.

[tex]x - 9 = 12 \times 2[/tex]

2) Simplify 12 × 2 to 24.

[tex]x - 9 = 24[/tex]

3) Add 9 to both sides.

[tex]x = 24 + 9[/tex]

4) Simplify 24 + 9 to 33.

[tex]x = 33[/tex]

Hence, the answer is 33.

Answer:

The equation of the line is;

y = 0.8x + 1

Step-by-step explanation:

Here, we want to get the equation of the line

The general equation of a straight line is;

y = mx + b

m

is the slope and b is the y-intercept

The y-intercept is simply the point on the y-axis where the line crosses the y-axis

we have this point at (0,1)

so we have;

y = mx + 1

to get m, we get any other point on the line and substitute its coordinates before we solve for m

we can identify the point (-2.5, -1)

substituting the coordinates

-1 = -2.5(m) + 1

-2.5m = -1-1

-2.5m = -2

m= 2/2.5

m= 0.8

so we have the equation of the line as;

y = 0.8x + 1

Answer:

15m

Step-by-step explanation:

a^2 + b^2 = c^2

a=?

b = 20m

c = 25m

a^2 + (20m)^2 = (25m)^2

a^2 + 400m^2 = 625m^2

a^2 = 625m^2 - 400m^2 = 225m^2

a = 15m

The answer is 15
