I have answered the questions that were not based on a diagram, since the diagrams are not attached.

The correct answers are:

C. Parallel line; B. Vertical; D compass and straightedge; B. 9°35′; A. side of a box.; D. the perpendicular from the line to the point; C. 14°48′; B. The amount of rotation of one side

Explanation:

To imagine a plane intersecting a cylinder, you can imagine a piece of paper cutting through a soup can. In both places the paper intersects the can, a straight line will be formed, and since the paper, intersects the can in the same way in both places, the lines will be parallel.

The vertical angles theorem tells us that any pair of vertical angles will be congruent.

To copy an angle, or construct an angle congruent to a given angle, we only need a compass and a straightedge. We can construct the copy of the angle using arcs and a given straight line segment.

The complement of an angle is the angle that, with the given angle, sums to 90°. There are 60' in one degree; since we have 25', we are lacking 60-25 = 35' for a complete degree. This would give us 81°; this means our complement will have 90-81 = 9°. This makes 9°35'.

A plane geometric surface is represented using a parallelogram. The only of these choices that is a parallelogram is the side of a box.

The shortest distance between two points is a straight line. This is represented from a point to a line as a perpendicular line between the two.

Supplementary angles are angles that sum to 180°. There are 60' in one degree; this means we lack 60-12 = 48' for the next degree. This would put us up to 166°. This means we would need 180-166 = 14°. This makes our answer 14°48'.

The size of an angle is based on the rotation of one of its sides. The more the side is rotated, the larger the angle.

How do you solve this?

puteri [66]

Answer:

Width: 7

Length: 14

Step-by-step explanation:

The area of a rectangle can be found my multiplying the length by the width. We do not know neither the length nor the width. However, we do know that the length is 7 feet longer than the width. Because we do not know the value of either side, let's let $x$ represent the width.

Since the length is 7 feet longer, we can represent the length by $x+7$ .

Now that we have our values for the length and the width we can multiply them together to find our area.

$(x)(x+7)=x^{2} +7x$

Now we have our equation, so we can address the changes made by the original question. The original question states that when 7 is added to both the length and width the area becomes 3 times larger. To do so simply increase each side by 7 by adding 7 to the original values.

$(x+7)(x+14)$

And multiply our area by 3.

$3(x^{2} +7x)$

set these equal to each other to find your new equation.

$(x+7)(x+14)=3(x^{2} +7x)$

Now you need to solve for $x$ . To do this first muliply $(x+7)$ and $(x+14)$ .

$(x+7)(x+14)=\\x^{2} +14x+7x+98=\\x^{2} +21x+98$

Then multiply $3(x^{2} +7x)$

$3(x^{2} +7x)=\\3x^{2} +21x$

Now you can begin solving for $x$ .

$x^{2} +21x+98=3x^{2} +21x$

Subtract $x^{2}$ from both sides.

$21x+98=2x^{2} +21x$

Subtract $21x$ from both sides.

$98=2x^{2}$

Divide by 2.

$49=x^{2}$

And finally take the sqaure root of both sides.

$\sqrt{x^{2} }=\sqrt{49}\\x=7$

Remember, because we are dealing with length, there cannot be negative. So while normally we would get both +7 and -7, in this case we only get +7.

Now that we have the value of $x$ , we can plug it into our original values.

For width we simply get 7.

For length we get 7+7=14

To check our answer we cna multiply 7 by 14 to get 98. Then we can add 7 to our length and width to get 14 and 21. Multiply these together and we get 294. 294 divided by 3 is 98, proving our answer correct.

Hi,
The conclusion should be letter B, if Karl runs 1mi, then he runs 5280 ft. In fact, that option is the only one in which you combine the information you have to get a conclusion.
