If a wheel makes 12 of a rotation in 2 seconds, what is the angular velocity, in radians per second?
Answer:
angular velocity = 12π Radians per second
Step-by-step explanation:
The angular velocity is a measure of the rotation/revolution speed of an object, relative to another point.
In order to present the answer in radians per second, let us first establish the relationship between radians and rotations/revolution.
one complete revolution = 360° = 2π Radians
∴ 1 roration = 2π Radians
12 rotations = 12 × 2π Radians = 24π Radians
Angular velocity in radians = 24π Radians in 2 seconds
Now let us convert to radians per seconds.
24π Radians = 2 seconds
2 seconds = 24π Radians
∴ 1 second = (24π Radians) ÷ 2
1 second = 12π Radians
∴ angular velocity = 12π Radians per second
2(I) A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same.
Which system of equations can be used to find the price in dollars of each large candle, , and each small candle, ?
Answer:
system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y is and .
Step-by-step explanation:
Here we have , A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. We need to find Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y . Let's find out:
Let the price in dollars of each large candle, x, and each small candle, y .So
A customer at a store paid $64 for 3 large candles and 4 small candles
Equation is :
⇒ .....(1)
At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles.
Equation is :
⇒ .......(2)
3(2)-(1) i.e.

So ,

⇒
Therefore , system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y is and .
System of equations which can be used to find the price in dollars of each large candle x and each small candle y is;
3x + 4y = 64
x + 8y = 68
Here we have,
A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. Price of each large candles are same and price of small candles are same for both customers.
What is system of equation?
A system of equations is a set of two or more equations with the same variables.
Now,
Let the price in dollar of each large candle = x
and, the price in dollar of each small candle = y
A customer at a store paid $64 for 3 large candles and 4 small candles.
So equation is;
⇒3 x + 4 y = 64 ----(i)
At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles.
So equation is;
⇒ x + 8y = 68 ------(ii)
3 (ii) - (i) ⇒
20 y = 140
y = 7
And, x = 12
Hence, System of equations which can be used to find the price in dollars of each large candle x and each small candle y is;
3x + 4y = 64
x + 8y = 68
And, price in dollars of each large candle is 12 and price in dollars of each small candles is 7.

A. 2270 feet
B. 2548 feet
C. 4455 feet
D. 9813 feet
If you can, show work. Thanks❤️
Step-by-step explanation:
A camera is positioned 5000 ft from the base of a rocket launching pad. the angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. let's assume the rocket rises vertically and its speed is 800 ft/s when it has risen2548 ft. (round your answers to three decimal places.)
Answer: B
Step-by-step explanation:
We are given an angle and a distance, and to solve for the height we need to make a triangle.
First, I'm going to assign sides to the triangle:
Side a: This is going to be the distance from the camera to the launch pad.
Side b: This is going to be the distance from the launch pad to the rocket (the rocket's height)
Side c: This is going to be the distance from the rocket to the camera (this is the hypotenuse of the triangle)
Now that we have sides, we can solve for the height. The height is the distance from the launch pad to the rocket, so it will be side b. We know that the camera is 5000 ft away from the launch pad, so we can say that side a is 5000 ft. It also tells us the camera is angled up at 27 degrees, so we can say angle B is 27 degrees.
We have a known side that length that is adjacent to a known angle inside of a right triangle, and we want to find the length of the opposite side. In this situation we can use the function tangent.
tan(theta) = opposite / adjacent
If we plug values into this equation we get:
tan(B) = b / a
tan(27 degrees) = b / 5000
b = tan(27 degrees) * 5000
b = 2547.627
b rounded to the nearest foot is 2548 ft, which is answer B

Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.

Andrew is paid £250 a week.
Each week, he
shares his pay with his sister in the ratio 3 : 2
saves 12% of his share.
How many weeks will it take Andrew to save £360?
Answer:
20 weeks
Step-by-step explanation:
The calculation of The number of weeks it will take to save £360 is given below:
Now $250 should be divided into a ratio of 3:2
He keeps = 150
And, he gives her = 100
As he saves 12% of his share
i.e.
= 12% of 150
= 18
Now the number of weeks is
= 360 ÷ 18
= 20 weeks

Porfavor: Elabora un problema matemático relacionado con tu vida cotidiana donde utilices “adición y sustracción de números con signo” y el resultado sea - 9
Answer:
Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.
El caso más simple para este tipo de problemas es algo como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"
Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)
Entonces el vuelto va a ser:
vuelto = $C - ($A + $B)
Y queremos que el resultado de este problema sea 9, entonces podemos escribir:
vuelto = $9 = $C - ($A + $B)
Ahora debemos encontrar los valores de las incógnitas.
Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:
$9 = $20 - ($2 + $B)
$9 = $20 - $2 -$B
$9 = $18 - $B
$9 - $18 = -$B
-$9 = -$B
Entonces $B será = $9.
Y el problema podría escribirse como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"
