Complete question :

Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above

sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who

has hooked a fish that is 10 meters below the surface of the water.

a. Use positive and negative numbers to represent the locations in relation to sea level.

Scottie =

Top of the lighthouse =

The boat =

The fish =

meters

b. How far is Scottie from the fish?

Answer:

30 m ;

15 m ;

0 m;

40 m

Step-by-step explanation:

Scottie's position = standing on cliff

Height of cliff = 30 m above sea level

Height of lighthouse = 15 meters

Position of fish = 10m below sea level

Above sea level = positive, +

Below sea level = negative, -

Scottie's position = 30 m

Top of lighthouse = 15m

BOAT = surface of sea = 0m

Fish = - 10 m

Distance of Scottie from fish :

Scottie's position - Position of fish

30m - (-10)m

30m + 10m

= 40m

Answer:

10 dollars

Step-by-step explanation:

4 / 2.80 = 1.42857142857

so that means 1.42857142857 is the cost of one apple.

1.42857142857 x 7 = 10

so your answer is,

it costs $10 for 7 apples.

I Hope this helped!

Answer:

an = 4n - 1

a1 = 3

a2 = 7 = 3 + 4

a3 = 11 = 3 + 4.2

a4 = 15 = 3 + 4.3

a5 = 19 = 3 + 4.5

.....

=> this is a arithmetic with a1 = 3 and d = 4

=> an = 3 + 4(n - 1) = 4n - 1

Answer:

The answer is below

Step-by-step explanation:

BE and CF are two equal altitudes of triangle ABC using RHS congruence rule prove that triangle ABC is isosceles.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

The RHS congruence rule states that if the hypotenuse and one leg of one triangle is equal to the hypotenuse and leg of another triangle; then the two triangles are equal. Two triangles are equal if they have three equal angles and three equal sides.

We have right angle triangles BEC and BFC

BE = CF (given)

CB = BC (both triangles have the same hypotenuse)

Hence ΔBEC = ΔBFC (RHS congruence rule)

Therefore; ∠BCE = ∠FBC (congruence theorem)

Since two angles of triangle ABC are equal (∠B = ∠C), therefore triangle ABC is an isosceles triangle and AB = AC

Answer:

80 rooms

Step-by-step explanation:

Given: 70 of the rooms in a hotel are full such that the hotel is 87.5% full.

To find: total number of rooms in the hotel

Solution:

Number of filled rooms [tex]=70[/tex]

Percentage if filled rooms [tex]=87.5\%[/tex]

Let [tex]x[/tex] denotes total number of rooms.

Therefore,

[tex]\frac{87.5}{100}x=70\\\\x= 70(\frac{100}{87.5} )\\\\x=80[/tex]

So, there are [tex]80[/tex] rooms in the hotel.

Answer:

D. (x, y) → (x, −y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.

The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.

The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.

The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.

The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

Answer:

C. The y-intercepts of the two functions are opposites.

Step-by-step explanation:

The y-intercept of g(x) is -1 and the y-intercept of h(x) is 1. -1 and 1 are opposites, so the two y-intercepts are also opposites.

Answer:

The answer is below

Step-by-step explanation:

A 2-column table with 4 rows. Column 1 is labeled Store with entries A, B, C, D. Column 2 is labeled Advertised Bread Prices with entries 3 loaves for 5 dollars and 94 cents, 4 loaves for 7 dollars and 80 cents, 5 loaves for 10 dollars and 5 cents, 6 loaves for 12 dollars and 12 cents.

Camillo is making gourmet peanut butter and jelly sandwiches for a food challenge.

PLS HELP ASAP!!What is the unit price of a loaf of bread at each store?

Store A:

Store B:

Store C:

Store D:

Solution:

The unit price of an item is the price for a single unit of measure of that item. It is measured in price / unit measure.

unit price of a loaf of bread at each store = cost of the loaf of bread / number of loaves

For store A, unit price = $5.94 / 3 loaves = $1.98 per loaf

For store B, unit price = $7.80 / 4 loaves = $1.95 per loaf

For store C, unit price = $10.50 / 5 loaves = $2.10 per loaf

For store D, unit price = $12.12 / 6 loaves = $2.02 per loaf

Answer:

yup the person above me is right but for C its $2.01 :>

Perimeter = 5x+3

Step-by-step explanation:

Perimeter = (3x+1)+(x+2)+x

Perimeter = 5x+3

Answer:

m = 12

Step-by-step explanation:

Given

18 - m = 6 ( subtract 18 from both sides )

- m = - 12 ( multiply both sides by - 1 )

m = 12

Answer:

perimeter equals 66

sides: 23,23,10 10

Answer:

Step-by-step explanation:

0 quarter = 20 dimes

dime to quarter = divide by 20

quarter to dime= multiply by 20

4 quarters = ? dimes

4 x 20 = 80 dimes

0 dimes = ? quarters

0/20 = 0 quarters

5 dimes = ? quarters

5/20 = 0.25 quarters

Step-by-step explanation:

BUT I DID FIGURE THE FIRST ANSWER IS 13

(x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.

Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.

here, we have,

Given the rule of transformation:

(x, y) → (x+2, y+3)

If we move horizontally 2 units to the right, 2 is added to the x-coordinate of any given point, and then 3 units up.

In other words,

(x, y) → (x+2, y+3) means Translation 2 units right and 3 units up.

For example,

Let say if we have the point A(4, 5)

Using the translation rule:

(x, y) → (x+2, y+3)

A(4, 5) → A'(4 + 2, 5 + 3) → A'(6, 8)

Therefore, the new position of A(4, 5) after translating 3 units right and 2 units up would be: A'(6,8).

Hence, (x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.
