Answer:

107

Step-by-step explanation:

A circle is 360 degrees, so subtract 53,110, and 90 (right angle) from that.

Answer:

x = 107°

Step-by-step explanation:

a circle has 360°

to find 'x':

360-(53+90+110)

360 - 253 = 107

Answer:

The maximum number of tickets Susana can buy is 8.

Step-by-step explanation:

From the information provided, you can say that the total amount spent at the carnival would be equal to the price per ticket for the number of tickets purchased which can be expressed as:

c=3x, where:

c is the total amount spent

x is the number of tickets purchased

Now, you can replace c with 24 that is the amount Susana's parents gave her to spend at the carnival and then, solve for x:

24=3x

x=24/3

x=8

According to this, the answer is that the maximum number of tickets Susana can buy is 8.

Answer:

XZ = 42

Step-by-step explanation:

By the property of similar triangles,

"If two triangles are similar, their corresponding sides will be proportional."

By applying the property of similarity in ΔABC and ΔXYZ,

[tex]\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}[/tex]

[tex]\frac{4}{24}=\frac{8}{48}= \frac{7}{XZ}[/tex]

[tex]\frac{1}{6}= \frac{7}{XZ}[/tex]

XZ = 42

Therefore, length of unknown side XZ = 42 units.

Answer:

C) 4/(x+y)²

Step-by-step explanation:

start by expanding so it is written as 2÷(x+y)/(x+y)÷2.

Then rearrange so that it is 2×2/(x+y)×(x+y) or 4/(x+y)²

There is a cluster with a regression line of -0.4

Outliers:

(8,8) because it is not near the cluster that was said earlier.

Answer:

( C ) 428.1 ft²

Step-by-step explanation:

Alright, we know the surface area of a shape is the area the entire outside covers. So, we just need to find the areas of each side and add them together.

Let's start with the two rectangular sides. The dimensions of both of these are 10×12. The area of rectangles can be calculated by multiplying the length and width, so let's do that. Then, we will multiply this answer by two, so we have the areas of both rectangles.

10 · 12 = 120

120 · 2 = 240

The area of the two rectangular sides is 240 ft². We have 3 sides left to solve for.

Next, we will find the area of the triangular sides. Again, we will multiply the answer by two so we have the area of both. The area of the triangle can be found by multiplying [tex]\frac{1}{2}[/tex] the width by the height.

4.5 · 8.9 = 40.05

Multiply this by two for the area of both sides.

40.05 · 2 = 80.1

The area of the triangle sides is 80.1 ft².

The last side is also a rectangle, with the dimensions 9×12.

9 · 12 = 108

The bottom side has an area of 108 ft².

Now, we can add the areas together.

240 + 80.1 + 108 = 428.1

The surface area of the shape is 428.1 ft². The answer is C.

I hope this helps ^^

Good luck :)

Answer:

175

[tex] {cm}^{3} [/tex]

Step-by-step explanation:

Answer:

175cm3

Step-by-step explanation:

How to find the volume

In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width, and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

Multiply 25cm2 and 7cm

Therefore, the answer is 175cm3

Answer:

Step-by-step explanation:

(2x² - 3x  + 1 )(x - 3) = (2x² - 3x + 1)*x + (2x² - 3x + 1)*(-3)

                               = 2x²*x - 3x*x  + 1*x + 2x²*(-3) - 3x*(-3) + 1*(-3)

                               = 2x³ - 3x² + x -  6x² + 9x - 3

                               = 2x³ - 3x² - 6x² + x + 9x - 3 {Combine like terms}

                              = 2x³ - 9x² + 10x - 3

Answer:

7.26 to the nearest hundredth.

Step-by-step explanation:

The ratio opp/hyp is the sine of the angle.

So if we let the opposite side = x then

3.5/ 8.2 = x /17

x = (3.5 * 17) / 8.2

= 7.256

Answer:

[tex]\sqrt{80}[/tex]

Step-by-step explanation:

Pythagorean theorem (Gougu theorem) states that the hypotenuse squared is equal to the sum of the squares of two other sides. (a^2 = b^2 + c^2). Hence x^2 = 4^2 + 8^2 = 80.

As x squared is 80, x is the square root of 80.

You can factorise this into 4[tex]\sqrt{5}[/tex]

Answer:

x > 0

y > 0

Step-by-step explanation:

The first quadrant is the quadrant formed by the positive x-axis and the positive y-axis.

And we know that all the elements in this quadrant are larger than zero.

Then, a point (x, y) is on the first quadrant only if:

x > 0

y > 0

Note that we ignore the points with x = 0 or y = 0, this is because these points are shared between quadrants, and these points are not defined as belonging to any quadrant.

The two column proof is presented as follows;

Statements    [tex]{}[/tex]                                               Reason

1. [tex]\overline {HI}[/tex] ║ [tex]\overline {KL}[/tex], J is the midpoint of [tex]\overline {HL}[/tex] [tex]{}[/tex]         1. Given

2. ∠IHJ ≅ ∠JLK[tex]{}[/tex]                                            2. Alternate angles are congruent

3. ∠IJH ≅ ∠KJL   [tex]{}[/tex]                                         3. Vertically opposite angles

4.  [tex]\overline {HJ}[/tex] ≅ [tex]\overline {JL}[/tex]   [tex]{}[/tex]                                              4. Definition of midpoint

5. ΔHIJ ≅ ΔLKJ  [tex]{}[/tex]                                         5. By ASA rule of congruency

Step-by-step explanation:

Alternate angles formed by the crossing of the two parallel lines [tex]\overline {HI}[/tex] and [tex]\overline {KL}[/tex], by the transversal [tex]\overline {HL}[/tex] are equal

Vertically opposite angles formed by the crossing of two straight lines [tex]\overline {IK}[/tex] and [tex]\overline {HL}[/tex] are always equal

A midpoint divides a line into two equal halves

Angle-Side-Angle, ASA rule of congruency states that two triangles ΔHIJ and ΔLKJ, that have two congruent angles, ∠IHJ in ΔHIJ ≅ ∠JLK[tex]{}[/tex] in ΔLKJ and ∠IJH in ΔHIJ ≅ ∠KJL in ΔLKJ, and that the included sides between the two congruent angles is also congruent [tex]\overline {HJ}[/tex] ≅ [tex]\overline {JL}[/tex], then the two triangles are congruent, ΔHIJ ≅ ΔLKJ.
