Hello your question is incomplete below is the complete question

Raj correctly determined that ray LH is the bisector of AngleGLI. A line contains points K, L, M. 4 lines extend from point L. One line extends to point F, another to G, another to H, and another to I. Which information could he have used to determine this? AngleGLH Is-congruent-to AngleILM mAngleKLM = 5mAngleILM ,   mAngleGLI = 2mAngleGLH, mAngleGLI = mAngleGLH + mAngleHLI

answer :  mAngleGLI = 2mAngleGLH

Step-by-step explanation:

The information that could have used to determine this information is

mAngleGLI = 2mAngleGLH

from the figure,  we can see that

mAngleGLI = mangleGLH + mangleHLI  

Hence  we can conclude mangleGLH = mangleHLI

therefore the  ray LH bisects angleGLI into two equal angles GLH & HLI.

Answer: mGLI = 2mGLH

Answer:

g=7

Step-by-step explanation:

10g–7g–3=18

subtract 7g from 10 g

3g-3=18

add 3 to both sides

3g=21

divide each side by 3

g=7

Answer:

g=7

Step-by-step explanation:

We move all terms to the left:

10g-7g-3-(18)=0

We add all the numbers together and all the variables

3g-21=0

We move all the terms containing "g" to the left and all the other terms to the right

3g=21

g=27/3

which is the same as

g=3

Answer:

3 feet

Step-by-step explanation:

To begin, find the width of the first painting by dividing 32 by 4. You get 8 feet as the width. Since the second painting has a width of 8, divide 24 by 8 to get the length (area of a rectangle is length times width). You get that the length of the second painting is 3 feet.

Table 2 depicts the proportional relationship between x and y as 2/5 = 4/10 = 6/15.

Therefore,

1x / y

Simplifying the equation, then we get,

1/4  =  2 /8 =  3 / 12  = 6 / 24

=  2 / 8

y l x

Put the value of x and y in above equation,

4/1  = 8 /2 = 12/3

8/2

5/2 = 10 /4

= 15 /6

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle. Sum the 3 sides and equate to 51, that is

15 + 5x - 6 + 2x = 51

7x + 9 = 51 ( subtract 9 from both sides )

7x = 42 ( divide both sides by 7 )

Answer: a=36pi

Step-by-step explanation:

We know that the formula for the area of a circle is a=(pi)(r)^2

Knowing that the diameter is 12 we can find the radius is 6 as the radius is half of the diameter. Now we can plug that into the equation. a=pi*6^2

Simplify

Step-by-step explanation:

A normally distributed set of data has been generated where 50% of the data lies below 97 and 70% lies below 104. Then, mean of the data is equal to 97 and standard deviation is equal to 13.358.

Normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Given that 50% of the data lies below 97, implies that median of the data is equal to 97. In a normal distribution, mean = median = mode, therefore, mean = 97.

Given the mean and value at 70th percentile, we can find the standard deviation.

Using the z score - percentile table, we find that the z score corresponding to the given percentile.

z score corresponding to 70th percentile = 0.524

[tex]0.524 = \frac{x - mean}{standard\ deviation}\\ \\0.524 = \frac{104 - 97}{standard\ deviation} \\\\standard\ deviation = \frac{7}{0.524} = 13.359[/tex]

Answer: 8/9

Step-by-step explanation:

First, we can find a common denomiator.

The least common multiple of 2, 9, and 6 is 18.

Therefore, the lcd is 18.

1/2 = 1/2 * (9/9) = 9/18

2/9 = 2/9 * (2/2) = 4/18

1/6 = 1/6 * (3/3) = 3/18

Therefore, 1/2 + 2/9 + 1/6 = 9/18 + 4/18 + 3/18.

We can add the numerators together.

= 16/18

Divide the nuumerator and denominator by 2:

= 8/9

The circumference of the outer edge of the path around the pool is 113.04 ft.

The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.

Given

A circular swimming pool has a radius of 15 ft.

There is a path all the way around that pool that is three feet wide.

A circle has a radius of 15 feet.

A larger circle goes around the smaller circle that is 3 feet wide.

The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.

The radius of the outer edge of the path around the pool = 15 + 3

The radius of the outer edge of the path around the pool = 18ft

The circumference of the outer edge of the path around the pool is;

[tex]\rm Circumference=2\pi r\\\\Circumference = 2\times 3.14 \times 18\\\\Circumference=113.04 \ ft[/tex]

Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.

Answer:

4 years

Step-by-step explanation:

Sara saved $16,000 for a new car that costs $10,500, plus $1200 each year for insurance.

Let the number of years she can pay for insurance be written as: x

$10,500 + $1200 × x = $16,000

$1200 × x = $16,000 - $10,500

x = $5,500/1200

x = 4.5833333333 years

Since the number of years is in decimal, we would pick the whole number there as the maximum number of years.

Therefore, the maximum number of years, x, she could pay insurance with her current savings is 4 years.

Answer:

the slope intercept form of this line is y = -4x + 9.

Step-by-step explanation:

The equation of line is given by:

y = mx + b          .....[1]

where,

m is the slope of line

b is the y-intercept.

As per the statement:

Given: The rate of change = -4

Substitute in [1] we have;

y = -4x + b

Substitute the values of  any (x, y) from the given table.

Let x = -1 and y = 13

then;

13 = -4(1-)+b

⇒13 = 4+b

Subtract 4 from both sides we have;

9 = b

or

b = 9

⇒the equation become, y = -4x+9

Therefore, the slope-intercept form of this line is,  y = -4x+9
