what is area
to count the inside of a shape
to count the out side of a shape
none of the above
Answers
Area refers to the amount of space inside a shape and is found by counting the inside of the shape. Therefore, the correct answer is option a.
"To count the inside of a shape": This means that when we calculate the area of a shape, we are determining the amount of space or surface area that is enclosed within the boundaries of that shape. In other words, it's the measurement of the total space covered by the shape, and it doesn't include the outer boundary or perimeter.
"To count the outside of a shape" is not an accurate definition for area. The outside of a shape is typically referred to as the perimeter or the circumference, and it represents the measurement of the boundary or the length of the outline of the shape.
"None of the above" is not the correct choice because the area is indeed about measuring the inside of a shape, as explained in the first option.
In summary, when we calculate the area of a shape, we are quantifying the space enclosed within the shape's boundary, not the space on the outside of it.
Therefore, the correct answer is option a.

Which of the following statements about special angle relationships is not correct?
A. It is possible for angles to be both vertical and complementary.
B. It is possible for an obtuse angle to have both a complement and a supplement.
C. It is possible for an acute angle to have both a complement and a supplement.
D. It is possible for angles to be both congruent and supplementary
Answers
Second choice: It is possible for an obtuse angle to have both a complement and a supplement.
Explanation:
Let's examine the given choices:
First choice:
It is possible for angles to be both vertical and complementary.
Vertical angles are equal angles.
Complementary angles means that the two angles add up to 90 degrees.
Two angles can be both vertical and complementary if the measure of each is 45. By this, the two angles are equal and their summation is 90 degrees.
Therefore, this statement is correct
Second choice:
It is possible for an obtuse angle to have both a complement and a supplement.
Complement angles means that their sum is 90 degrees.
Supplement angles means that their sum is 180 degrees.
Since the measure of an obtuse angle is greater than 90, therefore, it cannot have a complement.
Therefore, this statement is not correct
Third choice:
It is possible for an acute angle to have both a complement and a supplement.
Complement angles means that their sum is 90 degrees.
Supplement angles means that their sum is 180 degrees.
Since the measure of an acute angle is less than 90, therefore, it can have both a complement and a supplement.
Therefore, this statement is correct
Fourth choice:
It is possible for angles to be both congruent and supplementary
Congruent angles means that they are equal
Supplement angles means that they add up to 180 degrees.
Two angles can be both congruent and supplement if the measure of each is 90. By this, the two angles are equal and their summation is 180 degrees.
Therefore, this statement is correct
Based on the above, the only incorrect statement is the second choice.
Hope this helps :)
Answer:
B.) It is possible for an obtuse angle to have both a complement and a supplement.
Step-by-step explanation:
Rules for an obtuse angle:
It cannot be smaller than or be 90°It can not be bigger than or be 180°To create a complementary or supplementary angle, you can use 2 angles and no more than 2.
Say we used an obtuse angle (like the one in the picture below), since an obtuse angle can not be or be greater than 90°, an obtuse angle can not be complementary.
We can not fit 2 obtuse angles at 180°, because of that, an obtuse angle(s) can not create a supplementary angle.
Therefore, B would be the correct answer.

Jane bought 10 pears and 11 oranges for $10.05 the total cost of one pear and one orange was $0.94 how much did 1 pear and 1 orange cost
Please Send Help
Answers
If 10 pears and 11 oranges cost 10.05 and the total cost of 1 pear and 1 orange is 0.94, then they should cost 0.47 cents each:
0.47 + 0.47 = 0.94
0.94 divided by 2 = 0.47
Hope this helps you.
Have a great day!
The cost of one pear and one orange is $0.94.
Explanation:To find the cost of one pear and one orange, we need to set up an equation. Let's let x be the cost of one pear and y be the cost of one orange. We can set up two equations based on the given information:
10x + 11y = 10.05 (equation 1)x + y = 0.94 (equation 2)We can solve this system of equations by substitution or elimination. Let's use the substitution method. From equation 2, solve for x in terms of y:
x = 0.94 - y
Substitute this expression for x into equation 1:
10(0.94 - y) + 11y = 10.05
Distribute and simplify:
9.4 - 10y + 11y = 10.05
Combine like terms:
9.4 + y = 10.05
Subtract 9.4 from both sides:
y = 10.05 - 9.4
y = 0.65
Now substitute the value of y back into equation 2 to find x:
x + 0.65 = 0.94
Subtract 0.65 from both sides:
x = 0.94 - 0.65
x = 0.29
Therefore, the cost of one pear and one orange is $0.29 + $0.65 = $0.94.

Step-by-step explanation: We are given a figure with two similar triangles with sides of lengths x, 15 and corresponding sides of lengths 15 and 25 respectively.
Since the given triangles are similar, so their sides will be proportional.
Therefore, we have
[tex]\dfrac{x}{9}=\dfrac{25}{15}\\\\\\\Rightarrow \dfrac{x}{9}=\dfrac{5}{3}\\\\\\\Rightarrow x=\dfrac{5\times 9}{3}\\\\\Rightarrow x=15.[/tex]

Answers
Carmen used the associative property of addition to solve the given problem.
The associative property means one can add or multiply the given numbers regardless of how they are grouped. In other words, if one is adding or multiplying it does not matter where the brackets are placed.
The given problem is -
17 + (45 + 23), 17 + (23 + 45), (17 + 23) + 45
So here the sum of all the three patterns is 85. This clearly proves that forming groups does not affect the sum. So this is based on associative property of addition.

At Saturday night’s football game there were 18 less fans than half the fans at Friday night’s game. There were “x” fans at Friday’s game. Write an expression to represent the number of fans at Saturday’s game
Answers
The expression to represent the number of fans at Saturday's game when there were 'x' fans on Friday is (1/2)x - 18.
Explanation:To find the number of fans at Saturday's football game based on the given information that there were 'x' fans at Friday's game, we will write a mathematical expression. According to the statement, there were 18 fewer fans than half of the fans on Friday night. The expression for half of the fans at Friday's game is (1/2)x and we subtract 18 from this to account for the 18 fewer fans. Therefore, the expression representing the number of fans at Saturday's game is (1/2)x - 18. This expression can be used to determine the number of fans at Saturday's game once the number of fans on Friday (x) is known.
The expression representing the number of fans at Saturday's game, based on the fact that there were 18 less than half the number of fans at Friday's game (represented by x), is (x/2) - 18.
Explanation:The question we are addressing involves writing an expression to represent the number of fans at Saturday's football game, with the information that there were 18 less fans than half the number of fans at Friday night's game, and there were x fans at Friday's game.
Let's start with the number of fans at Friday's game, which is represented by x. Since we know that Saturday's game had 18 less than half of that amount, we first need to find half of x. To do that, we divide x by 2: (x/2). Now, to reflect that there were 18 fewer fans on Saturday, we subtract 18 from half of x: (x/2) - 18. Consequently, the expression that represents the number of fans at Saturday's game is (x/2) - 18.
This expression allows us to plug in the actual number of fans from Friday's game (when we know it) to determine the number of fans that attended Saturday's game.

“Lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?”
Answers
Let's calculate ∠O:
∠O=180-2*56=68+
x=90-68=22°
To solve the problem we will first name all the points given to us, and then we will find ∠O, and then we will find the value of x.
The value of x is 22°.
Given to us
∠OAB = 56°
Looking at the diagram below,
In ΔAOB
OA = OB = R, the radius of the circle O,
therefore, the ΔAOB is an isosceles triangle, with OA, OB as the congruent sides and AB as the base of the triangle.
Thus, ∠OAB = ∠OBA = 56°
What is the sum of all the angles of a triangle?Sum of all the angles of a triangle = 180°
∠O + ∠AOB + ∠OBA = 180°
We know ∠AOB = ∠OBA, therefore,
∠O + 2(∠AOB) = 180°
∠O + 2(56°) = 180°
∠O = 68°,
In ΔOBC,
BC is the tangent to the circle O, therefore,
∠OBC = 90°
Sum of all the angles of a triangle = 180°
∠O + ∠OBC + ∠OCB = 180°
68° + 90° + ∠OCB = 180°
∠OCB = 180° - 68° - 90°
∠OCB = 22°
Hence, the value of x is 22°.

A surveyor, Toby, measures the distance between two landmarks and the point where he stands. He also measured the angles between the landmarks in degrees.
What is the distance, x, between the two landmarks? Round the answer to the nearest tenth.
Answers
Side 1 = 55m
Side 2 = 65m
Angle 1 = 40°
Angle 2 = 30°
What we are looking for:
Toby's Angle = ?
The distance x = ?
We need to look for Toby's angle so that we can solve for the distance x by assuming that the whole figure is a SAS (Side Angle Side) triangle.
Solving for Toby's Angle:
We know for a fact that the sum of all the angles of a triangle is 180°; therefore,
180° - (Side 1 + Side 2) = Toby's Angle
Toby's Angle = 180° - (40° + 30°)
Toby's Angle = 110°
Since we already have Toby's angle, we can now solve for the distance x by using the law of cosines r² = p²+ q²− 2pq cos R where r is x, p is Side1, q is Side2, and R is Toby's Angle.
x² = Side1² + Side2² - 2[(Side1)(Side2)] cos(Toby's Angle)
x² = 55² + 65² - 2[(55)(65)] cos(110°)
x² = 3025 + 4225 -7150[cos(110°)]
x² = 7250 - 2445.44
x = √4804.56
x = 69.31m
∴The distance, x, between two landmarks is 69.31m
