Answer: 2.456 x 10 to the power 11
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
x=25
Step-by-step explanation:
All angles in a triangle add up to 180°, so add all the angles together
(2x+15)+(x+10)+(3x+5)=6x+30
So that means... 6x+30=180°
Get rid of the 30, so... 180-30=150
6x=150°
Divide each by 6
6x/6=x
150/6=25
x=25

Answer:
y = 1500 + 800x
Step-by-step explanation:
This is the answer because Elisa charges 1500 dollars no matter what. That value is not dependant on anything. Every hour she is with the client is 800 dollars. That is why it is represented as 800x. X being the amount of hours. You add the two together to find how much Elisa's services cost.

A rhombus has 4 equal sides.
What is the order of rotational symmetry for a rhombus?
1
2

Answer:
B. 2
Step-by-step explanation:
Got Correct On MyPath.
The order of rotational symmetry for a rhombus is 2.
What is Polygon?A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end
A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral.
In a rhombus, opposite sides are parallel and the opposite angles are equal.
All the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles
Rotational Symmetry of a Rhombus has four equal sides but of varying angles.
A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees
Hence, the order of rotational symmetry for a rhombus is 2.

The heights of six students Aaron, Betty, Carrie, Dan, Evelyn and Frank are 58 inches, 60 inches, 63 inches, 64 inches, 68 inches and 69 inches. Carrie is 4 inches shorter than Aaron. The girls (Betty, Carrie and Evelyn) are the three shortest students. Dan is one inch shorter than Frank. Betty is the shortest student. What is the sum of Frank’s height and Evelyn’s height, in inches?
Answer: 132
Step-by-step explanation: I think it is 132 because C + 4 = A, D + 1 = F, and B is shortest. so the order is FDAECB with Frank at 69 and Evelyn at 63. Carrie has to be at 60 because Aaron, who is 64, is 4 inches taller than Carrie. So, when you add 69 and 63 together, you get 132. Also just to check, Dan, who is 68, is one inch shorter than Frank, who is the tallest. This is only true because the girls are the youngest.
Answer:
132

Identify the coordinate of the point shown on the number line. A number line from negative 30 to 10. Major tick marks are on every ten numbers and minor tick marks are on every number. A point is plotted three ticks to the left of 0 What is the coordinate of point P?
Answer:
The coordinates of the point P is -3
Please see attached number line
Step-by-step explanation:
The given information are;
The length of the given number line = The line extends from -30 to +10
The location of major tick marks = Every ten numbers
The location of minor tick marks = Every number
The location of the point P = Three ticks to the left of 0
Therefore, the coordinates of the point P = -3
un icosagono es un poligono que contiene 20 lados, cuantas diagonales se pueden trazar desde todos sud vertices si cada lado mide 15cm y su area es 900cm2?
Answer:
El número de diagonales de un icoságono = 170 diagonales
Step-by-step explanation:
Los parámetros dados son;
El número de lados del polígono = 20
La longitud de cada lado = 15 cm.
El área del polígono = 900 cm²
La fórmula para encontrar el número de diagonales, ∑D, de un polígono de n lados se presenta como sigue;
Número de diagonales, ∑D = n (n - 3) / 2
Por lo tanto, el número de diagonales de un icoságono (20 lados) ∑D (20) es;
∑D (20) = 20 × (20 - 3) / 2 = 170 diagonales.
Se pueden trazar 170 diagonales en un icoságono.
Matemáticamente, es posible determinar la cantidad de diagonales en función del cantidad de lados del polígono a través de la siguiente fórmula:
[tex]d = \frac{n\cdot (n-3)}{2}[/tex] (1)
Donde:
[tex]d[/tex] - Cantidad de diagonales.[tex]n[/tex] - Cantidad de lados.Si sabemos que [tex]n = 20[/tex], entonces la cantidad de diagonales del icoságono es:
[tex]d = \frac{20\cdot (20-3)}{2}[/tex]
[tex]d = 170[/tex]
Se pueden trazar 170 diagonales en un icoságono.

The temperature at 8 p.m. was 6 degrees. at 2 p.m. the temperature decreased 13 degrees. What was the temperature at 2 a.m.?
Step-by-step explanation:
Given parameters:
Temperature at 8pm = 6°C
Temperature at 2am = decreased by 13°C
Unknown:
Temperature at 2am
Solution:
Since this is a temperature decrease problem, the temperature at 2am should be lesser.
Temperature at 2am = Temperature at 8pm - Temperature decrease
= 6°C - 13°C
= -7°C
