Caleb has an assignment to draw a contour map. What type of landform is he most likely drawing?

marysya [2.9K]

The type of land form that Caleb most likely draws is a hill. The answer is option C- a hill.

Step-by-step explanation:

Contour lines are drawn to represent the changes in the elevation which helps to know the slope of the figure drawn.
If the contour lines are drawn close, then steeper the figure is. And more distant the lines are drawn, then less steep the figure is.
Here, the lines seem to be likely circle in shape. The distance of the outermost contour line is 20 ft. The next inner lines will have reduced values of 20 ft.
Therefore, the elevation gets reduced from higher to lower points which provides a diagram of a hill. Since there is no continuous high and low elevations, this cannot be a valley (a range of mountains).
Furthermore, The contour diagram for option A and D such as creek(water stream) or shoreline will have different and mixed values of elevations that seems to be a messy structure of contour lines.

(y x 1) + 2 and y + 2, is it equivalent or non equivalent?

enot [183]

Given:

The two expressions are

$(y\times 1)+2$

$y+2$

To find:

Whether the given expression are equivalent or non-equivalent.

Solution:

If two expressions are looking different but they are equal after simplification, then they are called equivalent expressions.

The first expression is

$(y\times 1)+2=y+2$

The first expression is equal to the second expression after the simplification.

Therefore, the given expressions are equivalent.

Please simplify these expressions

Oksana_A [137]

$10( - 2 - 9r) + 10(10 + 2r) = - 70r + 80 \\ 2(7n - 10) - 6(5n + 7) = - 16n - 62$

A math club is researching a golf tournament fund-raiser. it will cost $1,000 to host the tournament. if it rains, the club will

Readme [11.4K]

The expected value of tournament is $2600.

According to the statement

we have given that the tournament will cost $1000 and if it is sunny, it is expected that the club will collect $4,500 from the participants. And we have to find the expected value of a tournament.

So, we know that the

Cost of hosting the tournament : $1,000

If it rains, the club will lose the investment: $ -1,000

If it is sunny, the club will collect $4,500 ;

From all this the profit they will get

profit: 4,500 - 1000 = 3,500

And

There is a chance of 20% then

The club will loss the investment is

-1000*20 = -200

And

Effect on their profit if there is a rain then

3500*80 = 2800

then

The expected value of tournament is 2800-200=2600.

So,The expected value of tournament is $2600.
