Answer:

Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.

Step-by-step explanation:

Given that Bryan and Yuan left their homes at different periods of time and at different speeds, to determine how long they will meet and how much distance they will have traveled, the following calculation must be performed:

B = 5 + (3X)

Y = 4X

B = 5 + 3x2 = 11

Y = 4x2 = 8

B = 5 + 3x3 = 14

Y = 4x3 = 12

B = 5 + 3x4 = 17

Y = 4x4 = 16

B = 5 + 3x5 = 20

Y = 4x5 = 20

Therefore, Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.

Work Shown

45 girls : 15 boys

45/15 girls : 15/15 boys .... divide both parts by 15

3 girls : 1 boy

This tells us there are three times as many girls as there are boys.

We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.

Answer:

  c ≈ 14.9 cm

Step-by-step explanation:

I personally like to use a proportion that has the unknown in the numerator. The angle opposite c is ...

  C = 180° -150° -12° = 18°

Then the law of sines tells us ...

  c/sin(C) = b/sin(B)

  c = sin(C)·b/sin(B) = sin(18°)/sin(12°)(10 cm)

  c ≈ 14.9 cm

If the numbers after the decimal terminate, yes, it's rational.

9.521521521 = 9,521,521,521 / 1,000,000,000

If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.

If x = 9.521521521…, then

1000x = 9521.521521521…

Subtract x from this to eliminate the fractional part:

1000x - x = 9521.521521521… - 9.521521521…

999x = 9512

x = 9512/999

If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like

9.52152152119484929271283583457…

then the number would be irrational.

Step-by-step explanation:

The value of sinx=c/b, cosx=a/b and tanx=c/a.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given that, a right triangle has side lengths a, b, and c.

We know that, sinθ=Perpendicular/Hypotenuse, cosθ=Base/Hypotenuse and tanθ=Perpendicular/Bse

From the figure,

sinx=c/b, cosx=a/b and tanx=c/a

Therefore, the value of sinx=c/b, cosx=a/b and tanx=c/a.

Answer:

50x^4 +25x^3 +103x^2 +25x +49

Answer:

The equation of the line is y = 3x - 1 ⇒ b

Step-by-step explanation:

From the given graph

∵ The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex]

∵ (x1, y1) and (x2, y2) are two points on the line

∵ The line passes through points (0, -1) and (1, 2)

∴ x1 = 0 and y1 = -1

∴ x2 = 1 and y2 = 2

→ Substitute them in the rule of the slope to find it.

∵ m = [tex]\frac{2--1}{1-0}[/tex] = [tex]\frac{2+1}{1}[/tex] = [tex]\frac{3}{1}[/tex]

∴ m = 3

∵ The line intersects the y-axis at point (0, -1)

∴ The y-intercept = -1

∵ The form of the equation of the line is y = m x + b

∵ b is the y-intercept

∴ b = -1

→ Substitute the values of m and b in the form of the equation

∵ y = 3x + -1

∴ y = 3x - 1

∴ The equation of the line is y = 3x - 1

Answer: The mass of the sun is 3.51 x 10^3 times greater.

Step-by-step explanation:

X= Mass of Sun/ Mass of Saturn

X= 1.998 x 10^30 / 5.69 x 10^26

1.998/ 5.69 = .351

10^30 / 10^26 = 10^4

You want to move the decimal a value so you would subtract 1 from 4

3.51 x 10^3

The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The sun’s mass is [tex]1.998 * 10^{30}[/tex] kg.

Saturn's mass is [tex]5.69 * 10^{26}[/tex] kg.

Let the mass of the Sun be X times more than the mass of the Saturn mass.

The equation that can be written as

1.998 × 10³⁰ = X × 5.69 × 10²⁶

On simplifying, the value f X will be

[tex]\rm X = \dfrac{1.998 * 10^{30}}{5.69*10^{26}}\\\\X = 3511.42 \\\\X = 3.511 * 10^3[/tex]

The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

Step-by-step explanation:

Answer:

360 for first place and 240 for second

Step-by-step explanation:

Let's say f is the first place prize, and s is the second prize.

Amaal: 4f + 2s = 1920

Brian: f + 3s = 1080

Now we can isolate and substitute.

f = 1080 - 3s

4(1080 - 3s) + 2s = 1920

4320 - 12s + 2s = 1920

10s = 4320 - 1920

10s = 2400

s = 240

f = 1080 - 3*240

 = 1080 - 720

Step-by-step explanation:

Step one:

Given data

A store used to sell an MP3 for $72 and we are told that this 50% of the wholesale price.

Therefore the wholesale price is

72*2= $144

Required:

The special sales cost at 20% discount

Step two:

We are told that the special sale is at a 20% discount on the wholesale

= 20/100*144

=0.2*144

=$28.8

Therefore the special sales price is
