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:

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.

x = 13

Step-by-step explanation:

Use pythagorean theorem since you have a right angle. So [tex]c^{2} = a^{2} + b^{2}[/tex]

so in this case [tex]c^{2} = 5^{2} + 12^{2}[/tex]  so c = [tex]\sqrt{25+144}[/tex] and c = [tex]\sqrt{169}[/tex] so c = 13

for y=2x the x intercept is 0 and the y intercept is 0. for 7y=6x-20 the x intercept is 3.1 and the y intercept is 3

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

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

Answer:

a) 84π b) 109.2π

Step-by-step explanation:

The formula to find this is v=πr^2h/3

r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.

252/3=84

and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π

B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Step-by-step explanation:

its c for sure i got it right on a test

The value of y is -8.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

From the graph,

Two coordinates are (-2, 0) and (2, -2)

m = (-2 - 0) / (2 + 2) = -2/4 = -1/2

Now,

The equation of a line is y = mx + c.

(-2, 0) = (x, y)

y = mx + c

0 = (-1/2)(-2) + c

0 = 1 + c

c = -1

Now,

y = (-1/2)x - 1

Substitute x = 14.

y = (-1/2) x 14 - 1

y = -7 - 1

y = -8

Thus,

The value of y is -8.

Option (2)

Step-by-step explanation:

If a polygon is dilated by a scale factor = k

Rule to be followed,

(x, y) → (kx, ky)

Here, k = Scale factor

If 0 < k < 1, size of the image will be reduced.

If k > 1, size of the image will be enlarged.

Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.

Rule used for the transformation,

(x, y) → [tex](\frac{1}{4}x,\frac{1}{4}y)[/tex]

Here, scale factor by which MNPQR has been dilated is [tex]\frac{1}{4}[/tex]

Since, scale factor is between 0 and [tex]\frac{1}{4}[/tex], size of M'N'P'Q'R' will be reduced.

Therefore, size of pentagon M'N'P'Q'R' will be  smaller than pentagon MNPQR.

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
