Answer:
7.63 x 10⁷
Step-by-step explanation:
To convert to scientific notation you have to move the decimal place to where there is only one number in front of it. In this cause the number in front is 7. You have to maintain the same number of significant figures which in this case was 3 then multiply by 10 to the exponent of how many times you moved the decimal place.

The ordered pair (–2, 7) is viable.
The ordered pair (0, 7) is viable.
The ordered pair (17, 3) is viable.
The ordered pair (20, 5) is non-viable.
The conclusion which is correct among the answer choices as given in the task content is; The ordered pair (17, 3) is viable.
Which conclusion among the answers choices is correct?It follows from the task content that the conclusion which is valid be identified among the answer choices.
Since it is given that; there is a relationship between the number of visit and hole-in-one winners.
The statement above indicates that the number of visitors must be greater than the number of winners. This follows from the fact that there is no winner if there are no visitors.
Hence, since x is the number of visitors and y is the number of winners, the ordered pair which is viable is; (17, 3).
The ordered pair (20, 5) is viable too. However, the last answer choice indicates that it id not and hence, is incorrect.

here are the first 5 terms in a number sequence 7 10 13 16 19
write an expresstion, in terms of n, for the nth term of this number sequence.
Answer:
[tex]a_{n}[/tex] = 3n + 4
Step-by-step explanation:
there is a common difference between consecutive terms , that is
10 - 7 = 13 - 10 = 16 - 13 = 19 - 16 = 3
this indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 7 and d = 3 , then
[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

¿Cómo determinar los lados desconocidos de triángulos y rectángulos?
En este problema tenemos que dos casos de triángulos rectángulos y un caso de rectángulo. Por geometría euclídea, un rectángulo se forma uniendo dos triángulos rectángulos de iguales medidas. Las medidas de los lados faltantes se determina con el teorema de Pitágoras:
Caso A - Triángulo rectángulo
AC = √(BC² - AB²)
AC = √(5² - 3²)
AC = √(25 - 16)
AC = √9
AC = 3
Caso B - Rectángulo
AB = DC
AC = √(AD² + DC²)
AC = √(AD² + AB²)
AC = √(5² + 12²)
AC = 13

Define cube root.A integer y such that y3 = x is known as the cube root of a number x in mathematics. All nonzero complex numbers have three different complex cube roots, while all nonzero real numbers have exactly one real cube root and two complex conjugate cube roots. We are aware that adding three times to any number yields the cube of that number. Additionally, the inverse action of cubing a number is known as the cube root of a number. For instance, 63 has a cube value of 216. In that case, 216's cube root is equal to 6.

Option A is accurate because 35 pieces of pasta—the maximum permitted per necklace—are obtained by adding 12 macaroni noodles to 23 pieces of rotelle.
Option B is incorrect because the sum of the allowed 35 pasta pieces plus the 15 macaroni noodles and 21 rotelle pieces equals 36 pasta pieces.

Driver A and B have two different routes. Driver A's route is 80km, and driver B's route is 100km. Driver B travels 10km/h faster than driver A and finishes 10 minutes earlier. What are the speeds of each driver?
Speed of Driver A is 30 km/h.
Speed of Driver B is 40 km/h
Define speed.The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.
Given Data
Driver A and B have two different routes. Driver A's route is 80km, and driver B's route is 100km. Driver B travels 10km/h faster than driver A and finishes 10 minutes earlier.
Distance = Speed (Time)
Distance for Driver A: 80 kilometers
Consider Driver A's speed to be A km/h.
Driver A's time was [tex]\frac{80}{A}[/tex] hours.
Distance for Driver B is 100 kilometers
Speed of Driver B: A + 10 km/h
Driver B's time was equal to 100/(A + 10) hours.
Arrived 10 minutes early, or [tex]\frac{10}{60}[/tex], or [tex]\frac{1}{6}[/tex]hour.
100/(A + 10) = [tex]\frac{80}{A}[/tex] - [tex]\frac{1}{6}[/tex]
600A = 480(A + 10) - A(A + 10)
600A = 480A + 4800 - A² - 10A
A² +130A - 4800 = 0
A² + 160A - 30A - 4800 = 0
A(A + 160) - 30(A + 160) = 0
(A - 30)(A + 160) = 0
A = 30 since speed cannot be negative.
Speed of Driver A is 30 km/h.
Speed of Driver B: 40 km/h

Answer: The answer for X' is -1,8, and the answer for X'' is 3,14
Step-by-step explanation:
When talking about reflections across the x-axis, the formula would be: (x,y)---> (x, -y) so you first start out with -1, -8 then translate it to -1,8, because you swap the y. Then you add 4 to -1 because you move 4 to the right which gives you 3, and then you add 6 to 8 because you move up 6, which gives you 14, so your final answer is 3,14

what is the slope of a line perpendicular to the line whose equation is x+4=28
The slope of a line perpendicular to the line is -4
The equation is x -4y = 28
The equation for the line is
y = mx + c
where m = slope
c = y-intercept
Here the equation is x - 4y = 28
4y = x - 28
y = x/4 - 7
So the slope of this line is 1/4
Now we have to find the slope of the line perpendicular to that line.
We know that,
m1 × m2 = -1
1/4 × m2 = -1
m2 = -4
Therefore the slope of the line perpendicular to the line is -4.
