In ΔGHI, the measure of ∠I=90°, the measure of ∠G=5°, and IG = 57 feet. Find the length of GH to the nearest tenth of a foot.

Answer:

Step-by-step explanation:

If a point (x, y) is dilated by a scale factor of k, coordinates of the image point will be (kx, ky).

Rule that defines the dilation,

(x, y) → (kx, ky)

From the graph attached,

Coordinates of point A → (-4, 2)

Coordinates of image point A' → (-8, 4)

By the rule of dilation given,

A(-4, 2) → A'(-4k, 2k)

Since, A'(-4k, 2k) = A'(-8, 4)

Therefore, -4k = -8 ⇒ k = 2

1). Mistake in the answer → A is the preimage and A' is the image

   While A has been used as image and A' as preimage.

2). Always use the rule of dilation A(x, y) → A'(kx, ky)  

   Here, A and A' are the preimage and image points respectively.

   And 'k' is the scale factor by which point A has been dilated to form image point A'.

Answer:

360 degrees is a full circle.

Answer:

x = - 1

Step-by-step explanation:

Given

- 5 - 3 (x + 1) = - (- 4x + 1) ← distribute parenthesis on both sides

- 5 - 3x - 3 = 4x - 1

- 3x - 8 = 4x - 1 ( subtract 4x from both sides )

- 7x - 8 = - 1 ( add 8 to both sides )

- 7x = 7 ( divide both sides by - 7 )

x = - 1

Answer: 36

Answer:

d. y=5x-3

Slope-intercept form is y=mx+b.

m= slope

b= y intercept

so, m=5 and b= -3

Substitute with those values and then you have the equation.

Answer:

1/3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius  

h = height

If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100

the capacity of a cone is 1/3 that of a cylinder

Answer:

A: 19:26 B:7:8 C:26:45

Step-by-step explanation:

Question A

First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,

Boys

9+10=19

Girls

12+14=26

Now that you have the total number of boys and girls you make this ratio,

19:26

That is the final answer

Question B

For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,

Fifth Graders

12+9=21

Sixth Graders

14+10=24

Now that you have the total number of both of the different grades you make this ratio,

21:24

You can simplify this by finding the lowest common factor which would be

7:8

Question C

To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.

Girls

12+14=26

All

12+9+14+10=45

Now with the total number of both you will form a ratio

26:45

This is your final answer because you cant simplify this any further

Answer:

It is just .55*12,400

Step-by-step explanation:

thats literally all it is

Answer:

If you Meant (12,400) then around 6,820 planned to travel again

Step-by-step explanation:

Step-by-step explanation:

Given that,

Perpendicular = 17 units

Hypotenuse = 25 units

We need to find the value of x.

Using Pythagoras theorem to find x.

Hypotenuse² = base²+perpendicular²

25² = x² + 17²

x = 18.3 units

So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.

Answer:

C. $200 over $999 = x% over 100

Answer:

$240

Step-by-step explanation:

this would be solved using simultaneous equation

let c = cost of cds

d = cost of dvds

two equatiions can be derived from the question

5d + 9c = 285 eqn 1

5d + 5c = 225 equation 2

subtract equation 2 from 1

4c = 60

c = 15

substitute for c in eqn 1

5d + 9(15) = 285

5d = 150

d = 30

5(30) + 6(15) = 240
