1. Convert to decimal notation

The exponent is 11, making it 10 to the power of 11. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 11 time(s):

Answer:

-5/2

Step-by-step explanation:

5x+2y=6

First, put the equation in slope-intercept form

y = mx+b where m is the slope and b is the y intercept

Subtract 5x from each side

5x-5x+2y=-5x+6

2y = -5x+6

Divide each side by 2

2y/2 = -5/2x +6/2

y = -5/2 x +3

The slope is -5/2x

Lines that are parallel have the same slope

Explanation:

Polynomials of degree 1, aka linear polynomials, are the highest allowed for the divisor when using synthetic division. If the divisor is degree 2 and larger, then you'll need to use polynomial long division instead.

An example divisor of degree 1 is something like [tex]x+5[/tex], which can be written as [tex]x^1+5[/tex]. That exponent of 1 determines the degree.

Answer:

720 ways

Step-by-step explanation:

First place has 10 choices. First prize is chosen. So, 9 students are left.

Second place has 9 choices.

First and second prizes are chosen. Now 8 students are left

Third place has 8 choices.

Total ways = 10 * 9 * 8 = 720 ways

Answer:

Since the slope of the line is reciprocal to the given slope, then the line with a slope of 5/3 passes through the points (5, 7) and (10, 10).

The formula for calculating the slope of a line is expressed as:

We need to get the points that could pass through the line

Looking at the coordinate of option D (5, 7) and (10, 10). Get the slope:

Since the slope of the line is reciprocal to the given slope, then the line with a slope of 5/3 passes through the points (5, 7) and (10, 10).

Answer:

see explanation

Step-by-step explanation:

∠ A and ∠ FCE are corresponding angles and are congruent , then

∠ A = 150°

∠ FCE and ∠ C are vertically opposite angles and are congruent , then

∠ C = 150°

∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°

∠ ECB = 180° - ∠FCE = 180° - 150° = 30°

∠ E = 180° - (30 + 45)° ← sum of angles in a triangle

∠ E = 180° - 75° = 105°

∠ CBE and ∠ D are same- side interior angles and sum to 180° , then

∠ D = 180° - 45° = 135°

Answer:

a. 4

b. 1/4

c. 16

d. 1/9

e. 4/9

f. 9/16

Step-by-step explanation:

The ratio of the areas is the square of the ratio of the lengths of the sides.

a. Triangles G and F

Select a side in triangle G and the corresponding side in triangle F:

side in F: 10

corresponding side in G: 5

ratio of lengths of F to G = 10/5 = 2

ratio of areas of G to F: (2)^2 = 4

b. Triangles G and B

Select a side in triangle G and the corresponding side in triangle B:

side in G: 5

corresponding side in B: 5/2

ratio of lengths of B to G = (5/2)/5 = 1/2

ratio of areas of B to G: (1/2)^2 = 1/4

c. Triangles B and F

Select a side in triangle B and the corresponding side in triangle F:

side in B: 5/2

corresponding side in F: 10

ratio of lengths of F to B = 10/(5/2) = 4

ratio of areas of F to B: (4)^2 = 16

Do the same for the other 3 pairs of triangles.

The answers are:

d. 1/9

e. 4/9

f. 9/16

The ratio of the areas is the square of the ratio of the lengths of the sides.

Let's find the ratio of areas one by one:

A. Triangles G and F

Select a side in triangle G and the corresponding side in triangle F:

Side in F= 10

Corresponding side in G= 5

The ratio of lengths of F to G = 10/5 = 2

The ratio of areas of G to F= (2)^2 = 4

B. Triangles G and B

Select a side in triangle G and the corresponding side in triangle B:

Side in G= 5

Corresponding side in B= 5/2

The ratio of lengths of B to G = (5/2)/5 = 1/2

The ratio of areas of B to G: (1/2)^2 = 1/4

C. Triangles B and F

Select a side in triangle B and the corresponding side in triangle F:

Side in B= 5/2

Corresponding side in F= 10

The ratio of lengths of F to B = 10/(5/2) = 4

The ratio of areas of F to B: (4)^2 = 16

D. Triangles F and H

Select a side in triangle F and the corresponding side in triangle H:

Side in F= 10

Corresponding side in H= 10/3

The ratio of lengths of H to F = (10/3)/10 = 1/3

The ratio of areas of H to F: (1/3)^2 = 1/9

E. Triangles G and H

Select a side in triangle G and the corresponding side in triangle H:

Side in G= 5

Corresponding side in H=10/3

The ratio of lengths of H to G = (10/3)/5 = 2/3

The ratio of areas of H to G: (2/3)^2 = 4/9

F. Triangles H and B

Select a side in triangle H and the corresponding side in triangle B:

Side in H=10/3

Corresponding side in B= 5/2

The ratio of lengths of B to H = (5/2)/(10/3) = 3/4

The ratio of areas of H to G: (3/4)^2 = 9/16

The final answers are:

a. 4

b. 1/4

c. 16

d. 1/9

e. 4/9

f. 9/16

Answer:

[tex]x = \frac{41}{2} [/tex]

Step-by-step explanation:

x - 5 - 3x + 1 = -45

-2x - 4 = -45

-2x = -45 + 4

-2x = -41

x = 41 ÷ 2

x = 41/2

Step-by-step explanation:

[tex]\tt{}x - 5 - 3x + 1 = - 45[/tex]

[tex]\tt{} - 2x - 4 = - 45[/tex]

[tex]\tt{}- 2x= - 45 + 4[/tex]

[tex]\tt{} - 2x = - 41[/tex]

[tex]\tt{} x = \frac{41}{2} [/tex]

Answer:

x = -1

Step-by-step explanation:

x = -1

Answer:

1/4

Step-by-step explanation:

1. To find the slope, you can use the formula [tex]\frac{rise}{run}[/tex] to find it!

2. Rise means how many units you go up and down from point to point, and run means how far you go left or right from point to point.

3. Given the statement above, the rise would be 1, and the run would be 4.

4. Now, since slope is (rise)/(run), the slope is 1/4 because one divided by four is equal to one fourth.

Answer:

x = 11

Step-by-step explanation:

if the perimeters are equal then:

the perimeter of the first triangle : 3x + 9 + 3x + 3x + 8 = 9x + 17

the perimeter of the second triangle : 3x + 3x + 4x + 6 = 10x + 6 and

9x + 17 = 10x + 6 export like terms to the same side of the equation

17 - 6 = 10x - 9x

11 = x

we can find the lengths by replacing x with 11 in given expressions.
