Special right triangles

Answer:

Answer is Lee Ann wrote the right equation.

Step-by-step explanation:

2/8 equals 25%, which equals 1/4, half of 25% is 12.5%, so 25% plus 12.5% equals 37.5%.

37.5% in decimal form is 0.375.

Therefore Lee Ann is correct.

Answer:

its    -$3.17

Step-by-step explanation:

500-5=495

200-5=195

the remainder of the tickets is -$5

the expected value is $495 x 1/600 + $ 19583/600 + (-$5) 596/600= -$3.17

Answer:

Step-by-step explanation:

x-y=14

x-1/3y=1/10

-y=14-x

y=-14+x

take out the factors

x-10/30y=3/30

30x-10y=3

substitute

30x-10(-14+x)=3

30x+140-10x=3-140

20x/20=-137/20

x=-6.85

y=-14+(-6.85)

y=-20.85

The two numbers are 143/20 and 423/20.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that, the difference between two numbers is 14.

Let the smaller number be x and the larger number be y.

Here, y-x=14 ------------(i)

If 1/3 of the larger number is subtracted from the smaller number ,the result equals 1/10.

1/3 of larger number is 1/3 y

x-y/3 =1/10 ------------(ii)

From equation (i), substitute y=14+x in equation (ii), we get

x-(14+x)/3 =1/10

10(3x-14-x)=3

30x-140-10=3

20x-140=3

20x=143

x=143/20

Substitute x=143/20 in equation (i), we get

y-143/20=14

y=14+143/20

y=(280+143)/20

y=423/20

Therefore, the two numbers are 143/20 and 423/20.

Answer:

h(x) ≥ |x - 5| +1

Step-by-step explanation:

Given graph represents an absolute function (parent function)

f(x) = |x|

Since, graph of the function 'f' has been shifted 5 units to the right new function will be,

g(x) = f(x - 5)

g(x) = |x - 5|

Again function 'g' is shifted 1 unit upwards along the y-axis then the new function will be,

h(x) = g(x) + 1

h(x) = |x - 5| + 1

There is a shaded region representing the solution area lying above the intersecting dark lines,

Therefore, solution region will be re[presented by the inequality,

h(x) ≥ |x - 5| + 1

Answer: 31.2 pies

Step-by-step explanation:

Kim sold pies for $5.00 each and earned $156 from doing so.

The number of pies she sold to get to this was x pies.

The formula for doing so is therefore:

5 * x pies = 156

5x = 156

x = 156 / 5

= 31.2 pies

Answer:

Octagon

Step-by-step explanation:

Sum of interior angles = 3*360 = 1080

sum of interior angles, is also, s = (n-2)180

From that,

n-2)180 = 1080

n-2 = 1080/180

n = 6 + 2

n = 8

Therefore, the figure is an 8 sided polygon or an octagon

Answer:

number of sides of a polygon is 8(because the polygon is octagon)

sum of interior angle of a octagon=1080 degree

sum of exterior of a octagon = 360 degree

Step-by-step explanation:

here in question ,

interior angle of a polygon=3*360(exterior angle of a polygon is always 360 degree)

=1080

Answer:

it would be In 17 hours

Step-by-step explanation:

let me know if I am wrong or right thxs

Answer:

4 4/17 hours

Step-by-step explanation:

In one hour Jacob can paint 1/9 of the fence

In one hour Molly can paint 1/8 of the fence

This equation can determine how long it would take if they worked together:

1/9x + 1/8x = 1

multiply each term by lcm of 72 to eliminate denominators to get:

8x + 9x = 72

17x = 72

x = 72/17

x = 4 4/17 hours

Answer:

Total cost= $86.25

Step-by-step explanation:

Giving the following information:

Discount= 10%

Nill= $82.5

Tip= 15%

First, we need to calculate the discounted price:

Discount price= 82.5 / 1.1= $75

Now, the tip:

Tip= 75*0.15= $11.25

Finally, the total cost:

Total cost= 75 + 11.25

Total cost= $86.25

Answer:

Step-by-step explanation:

As in any "solve for" situation, you "undo" what is done to the variable.

Here, (for 3 of the 4 problems) the variable is ...

We undo these operations in reverse order. First, we add the opposite of the added constant. Then we divide by the coefficient of x². Finally, we take the square root to "undo" the squaring operation.

1. 4x² -30 = 22 . . . . . . given

  4x² = 52 . . . . . . . . . add 30 to both sides

  x² = 13 . . . . . . . . . . . divide both sides by 4

  x = ±√13 . . . . . . . . . take the square root. Both signs are solutions.

__

2. 3x² +4 = 166 . . . . . given

  3x² = 162 . . . . . . . . add -4 to both sides

  x² = 54 . . . . . . . . . . divide both sides by 3

  x = ±√54 . . . . . . . . take the square root. 54 = 3²·6 has a square factor

  x = ±3√6 . . . . . . . simplified result

__

3. (1/3)x² +14 = 36 . . . . given

  (1/3)x² = 22 . . . . . . . . add -14 to both sides

  x² = 66 . . . . . . . . . . . multiply both sides by 3

  x = ±√66 . . . . . . . . take the square root

__

4. The same "undo" idea applies. Here, we can start with the square root.

  (x -4)² = 16 . . . . . given

  x -4 = ±4 . . . . . . . square root

  x = 4 ± 4 . . . . . . add 4 to both sides

This means x = 4-4 = 0, or x = 4+4 = 8.

The solutions are x = 0, x = 8.
