A. What is the sum of all the interior angles in the kite?
B. Copy the kite and draw the diagonals. What is the measure of the angle at which the diagonals intersect?
Answer:
A. 360 degrees
B. 360 degrees all the way around but each individual one is 90 degress
Step-by-step explanation:
Answer:
Step-by-step explanation:
B: the kite's diagonals intersect each other at a 90o degree angle.
A: It should come to 360. Let's if that happens.
Take the top angle (88) first. Notice that if you draw in both diagonals, the will form Isosceles triangles. Let's deal with the shorter diagonal first.
The two angles at the base of the shorter diagonal are equal. That's because the sides opposite them are equal.
2x +88 = 180 Subtract 88 from both sides.
2x = 92 Divide by 2
x = 46
Now lets look at the long narrow legs of the bottom isosceles triangle.
2x + 50 = 180 Subtract 50 from both sides
2x = 130 divide by 2
x = 130 /2
x = 65
Now add up all the angles that make up the interior of the kite.
Total = 46 + 46 + 65 + 65 + 50 + 88
Total = 360 just as it should.

Step-by-step explanation:
A rectangle has sides measuring (2x + 7) units and (5x + 9) units.
Part A: What is the expression that represents the area of the rectangle? Show your work.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Part A
Use the FOIL rule to expand out the expression below
(2x+7)(5x+9)
2x*5x + 2x*9 + 7*5x + 7*9
10x^2 + 18x + 35x + 63
10x^2 + 53x + 63 is the final answer for part A
==========================================================
Part B
The degree is 2. This is a quadratic trinomial.
The degree is simply the largest exponent after expanding everything out. The degree directly determines the type of polynomial. Since the degree is 2, we have a quadratic. The polynomial is a trinomial because it has 3 terms.
==========================================================
Part C
Imagine we had a machine in which we deposit 2 coins into it. One would happen on either side. After the coins are deposited, a third coin pops out. The 2 coins going in and the third coin coming out are the same currency. This represents an example of closure.
In mathematics, the idea of closure is taking any two objects of the same type, applying an operation on them, and getting the same type of object as the input.
For example, we could take two whole numbers and multiply them together. The result is always a whole number. The set of whole numbers is closed under multiplication because you can't leave the set (hence the gate is closed not letting anything out).
Similarly, taking any two polynomials and multiplying them together will always lead to some other polynomial. Part A shows this in action because (2x+7), (5x+9) and 10x^2 + 53x + 63 are all polynomials.
[tex]\rm 10x^{2} + 53x + 63[/tex] is the expression that represents the area of the rectangle. This is a trinomial expression.
What is a quadratic equation?A quadratic equation is the polynomial of second degree in one variable only. The standard form of a quadratic equation is [tex]\rm ax^{2} +bx+c=0[/tex]
Where, x is the variable and a,b, and c are real numbers.
Part A
Let length of a rectangle = (2x+7)
Let width of a rectangle = (5x+9)
The area of the rectangle = length × width
= (2x+7)(5x+9)
= 2x × 5x + 2x × 9 + 7 × 5x + 7 × 9
= [tex]\rm 10x^{2} + 18x + 35x + 63[/tex]
Therefore, [tex]\rm 10x^{2} + 53x + 63[/tex] is the expression that represents the area of the rectangle.
Part B
The degree is 2 in the expression. This is a trinomial expression.
The degree is simply the largest exponent. The degree directly represents the type of polynomial. Since the degree is 2. The polynomial is a trinomial because it has 3 terms.
Part C
Applying multiplication operations such that taking any two polynomials and multiplying them together will always lead to some other polynomial. Part A shows this multiplication because (2x+7), (5x+9) and [tex]\rm 10x^{2} + 53x + 63[/tex] are all polynomials.

The figure is made up of a cylinder and 2 cones. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth.
Please help!!!!!
A cylinder and 2 cones. All have a radius of 2 millimeters. The cones have heights of 4 millimeters and 2 millimeters, and the cylinder has a height of 5 millimeters.
Recall the formulas V = B h and V = one-third B h
Answer——————- millimeters cubed
Answer:
96.29 mm^3
Step-by-step explanation:
Cylinder
V = pi r^2 h
V = 3.14 ( 2)^2 ( 5)
V = 3.14 *4*5
V =62.8 mm^3
Cone
V = 1/3 pi r^2 h
V = 1/3 (3.14) 2^2 ( 4)
V =1/3 (3.14) 4*4
V =16.746666666 mm^3
There are 2 cones so multiply by 2
Both cones = 33.493333333333 mm ^3
Add the cones and the cylinder together
62.8+33.493333333 =96.293333333

Answer:
a) (x +2)(x +3)
b) x = -2 or -3
Step-by-step explanation:
a) The constants in the binomial factors will be divisors of 6 that have a sum of 5. You know that ...
6 = 1×6 = 2×3
The sums of these factor pairs are 7 and 5. You want the pair 2, 3. The factors are ...
x² +5x +6 = (x +2)(x +3)
__
b) The solutions to the equation are the values of x that make the factors zero:
(x +2) = 0 ⇒ x = -2
(x +3) = 0 ⇒ x = -3

Answers:
6. A) 120 plus or minus 17. A) (0, 22.7)8. B) When there are 0 people, the max noise is 22.7 dB9. D) 8910. B) The player had 318 at bats and 80 hits.========================================================
Explanations:
6. Plug in x = 65 and evaluate. You should get y = 120.2 which is fairly close to 120, give or take a decibel or so. 7. The y intercept is the value of b in y = mx+b. In this case, b = 22.7 and the location of the y intercept is (0, b) = (0, 22.7)8. Plug in x = 0 and you should get y = 22.7, which is the y intercept mentioned earlier. It means that if x = 0 people show up, ie the stadium is empty, then the noise level is 22.7 dB. This is probably unrealistic as there's no people around to make noises, unless there are machinery or similar making sounds. 9. Form the proportion 147/526 = x/317. Solve for x to get roughly x = 88.591, which rounds to 89. If we have 89 in this cell, then the row relative frequencies will fairly be the same (ie each row is pretty much identical after we compute the row relative frequencies) and that leads to a likely case we don't have association. 10. The point (x,y) = (318, 80) means x = 318 and y = 80 pair up together. The variable x is the number of at bats, and y is the number of hits.

What’s the distance between the points that’s given on the graph?
The distance between two points:
[tex] \large \boxed{ \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } }[/tex]
From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:
[tex] \large{d = \sqrt{ {( - 3 - 5)}^{2} + {(1 + 4)}^{2} } } \\ \large{d = \sqrt{ { (- 8)}^{2} + {5}^{2} } } \\ \large{d = \sqrt{64 + 25} \longrightarrow \sqrt{89} } [/tex]
Hence the distance between two points is √89.
Answer
√89At a sale, each book was marked $3.00 off the original price. Daniel paid $46.00 for two books that had the same sale price. What was the original cost of ONE of his books?
Answer:
The answer would be $26.00
Step-by-step explanation:
Taking into consideration that Daniel has 2 books and is paying $46.00 with the discounted prices, we can say that if there was no discount, the full price would be $52, since there's 2 books, it would be 3•2= 6 and $49 + 6 = $52. Now knowing the original pricing for two books, we can now divide the number by 2 and get $26.00.

Answer:
m∠1 = 147°
Step-by-step explanation:
(5x-2)° and ∠1 are supplementary to each other, which means they add up to 180°. However, we don't know the measure of ∠1. So, we need to solve for x to figure out angle (5x-2)°'s measure. Therefore:
(8x+1)°+(5x-2)°+90°=180°
8x+1+5x-2+90=180
13x+89=180
13x=91
x=7
This means the measure of angle (5x-2)° is 33°, making the measure of ∠1 equal to 147°.

11.54 + 2 x 4 - 8 ÷ 2 = 14.54
What is the solution to this equation?
8x-2(x - 5) = x + 25
A. x= 3
B. x= 7
C. x = 6
D. X= 4
Answer:
x=3
Step-by-step explanation:
8x-2(x - 5) = x + 25
Distribute
8x -2x+10 = x+25
Combine like terms
6x +10 = x+25
Subtract x from each side
6x-x +10 = x+25-x
5x +10 = 25
Subtract 10 from each side
5x-10+10 =25-10
5x= 15
Divide each side by 5
5x/5 =15/5
x=3
Answer:
A. x = 3
Step-by-step explanation:
8x- 2(x - 5) = x + 25
Using distributive property
8 x - 2 x - 10 = x + 25
combine like terms
6 x - 10 = x + 25
subtract both side from x
6 x - x - 10 = x - x + 25
5 x - 10 = 25
Add 10 to both side
5 x - 10 + 10 = 25 - 10
5 x = 15
Divide both side by 5
5 x / 5 = 15 / 5
x = 3
