Answer:
0.63 or 63/100
Step-by-step explanation:
Answer:
0.63
Step-by-step explanation:
For this you would want to do the reverse operation. So you see that it is multiplication? You would have to do division to get n by itself. When you divide 630 by 1,000 you would get 0.63.

Elena biked 8 miles on Saturday. Use the double number line to answer the questions. Be prepared to explain your reasoning. A) What is 100% of her Saturday distance? B) On Sunday, she biked 75% of her Saturday distance. How far was that? C) On Monday, she biked 125% of her Saturday distance. How far was that?
Answer:
A - Since Elena biked for 8 miles on Saturday, 100% of her distance traveled was 8 miles.
B - Now, on Sunday she traveled 75% of what she traveled on Saturday, which arises from the following calculation:
8 x 0.75 = X
6 = X
So on Sunday she traveled 6 miles.
C - Finally, on Monday she traveled 125% of what she traveled on Saturday, which arises from the following calculation:
8 x 1.25 = X
10 = X
So on Monday she traveled 10 miles.

Which statements involving cosine and sine are true? Check all that apply.
sin(–45°) = –sin(45°)
sin(–45°) = sin(45°)
cos(–45°) = –cos(45°)
cos(–45°) = cos(45°)
cos(–45°) = sin(–45°)
Answer:
sin(–45°) = –sin(45°)
cos(–45°) = cos(45°)
Step-by-step explanation:
The statements which involving cosine and sine are true are sin(–45°) = –sin(45°) and cos(–45°) = cos(45°).
What are Trigonometric Ratios?Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.
The main three trigonometric ratios are sine, cosine and tangent functions.
Trigonometric functions are also called as Circular functions.
There are five statements given.
We have the identities that,
sin (-x) = - sin(x) and
cos (-x) = cos x
Using this for each of the statement,
sin(–45°) = –sin(45°) is true.
sin(–45°) = sin(45°) is false
cos(–45°) = –cos(45°) is false
cos(–45°) = cos(45°) is true
For the last one,
cos(–45°) = cos (45°) = sin (45°) ≠ sin(–45°)
So this is false.
Hence the true statements are sin(–45°) = –sin(45°) and cos(–45°) = cos(45°).

Encuentra la forma de la ecuacion de la recta que pasa por el punto P(-1,5) y que es perpendicular a la recta 2x + 3y - 8= 0
Responder:
2y-3x = 12
Explicación paso a paso:
La forma estándar de ecuación de una línea se expresa como;
y = mx + c
m es la pendiente
c es la intersección
Primero necesitamos la pendiente de la ecuación conocida;
Dada la ecuación 2x + 3y - 8 = 0
Vuelva a escribir en forma estándar;
2x + 3y = 8
3y = -2x + 8
y = -2x / 3 + 8/3
Por lo tanto, la pendiente de la línea dada es -2/3
Dado que la línea desconocida es perpendicular a la línea dada, el producto de sus pendientes será -1;
mM = -1
M = -1 (-2/3)
M = 3/2
La pendiente de la línea desconocida es 3/2
Obtener la intersección:
Sustituya m = 3/2 y el punto (-1, 5) en la expresión y = mx + cy obtenga c como se muestra;
5 = 3/2 (-1) + c
5 = -3/2 + c
c = 5 + 3/2
c = (10 + 3) / 2
c = 13/2
Obtenga la ecuación requerida;
Dado que y = mx + c
y = 3x / 2 + 13/2
multiplicar por 2;
2y = 3x + 12
2y-3x = 12
De ahí que la forma de la ecuación de la recta que pasa por el punto P (-1,5) y que es perpendicular a la recta 2x + 3y - 8 = 0 es 2y-3x = 12

If a windmill with radius 26 feet makes 12 full revolutions every 1 minute, what is its linear speed?
The linear speed of the windmill is 1,960.35 feet per minute.
Given data:
To calculate the linear speed of the windmill, determine the distance traveled by a point on the circumference of the windmill in 1 minute.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of the windmill is 26 feet, the circumference is:
Circumference = 2 * π * 26
Now, the windmill makes 12 full revolutions every 1 minute. Since one revolution is equivalent to one circumference, the total distance traveled in 1 minute is:
Distance = 12 * Circumference
Substituting the value of the circumference:
Distance = 12 * (2 * π * 26)
Simplifying this expression:
Distance = 24 * π * 26
Therefore, the linear speed of the windmill is equal to the distance traveled divided by the time taken, which is 1 minute:
Linear speed = Distance / Time
Linear speed = 24 * π * 26 / 1
Calculating this value, the linear speed of the windmill:
Linear speed ≈ 1,960.35 feet per minute
Hence, the linear speed is 1,960.35 feet per minute.

A number is called flippy if its digits alternate between two distinct digits. For example, 2020 and 37373 are flippy, but 3883 and 123123 are not. How many five-digit flippy numbers are divisible by 15?
Answer:
4 numbers
Step-by-step explanation:
Given
Five Digit Flippy Numbers
Required
Determine the number of these digits divisible by 15
Represent the format of this digits as: ABABA
A number is divisible by 15 if and only if it ends with 5 or 0
i.e.
[tex]ABABA = 0B0B0[/tex]
or
[tex]ABABA = 5B5B5[/tex]
The first format [tex]ABABA = 0B0B0[/tex] cannot be considered because the number starts with 0 which means that
[tex]ABABA = B0B0[/tex] ---- This is 4 digits not 5
Taking into consideration: 5B5B5
We know that 15 is a product of 5 and 3
i.e.
[tex]15 = 5 * 3[/tex]
5B5B5 is divisible by 5 because it ends with 5. So, for a number of this format to be divisible by 15, it must be divisible by 3
Numbers in this category are: 50505, 53535, 56565 and 59595
Hence, there are 4 five-digit flippy numbers divisible by 5.
