There are 15 boys and 45 girls competing in a race. What is the ratio of girls to boys in the race , lowest terms ?
Answers
==========================================
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.

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
= 360

A right triangle has side lengths a, b, and c as shown below.
Use these lengths to find sinx, tanx, and cosx.
Help plsss
Answers
Answer:
Step-by-step explanation:
The value of sinx=c/b, cosx=a/b and tanx=c/a.
What are trigonometric ratios?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.

The sun’s mass is 1.998 * 10^30 kg. Saturn’d mass is 5.69 * 10^26 kg. How many times as great as the mass of Saturn is the mass of the sun? Show your work using scientific notation
Answers
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.
What is division?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.

Bryan and Yuan started out at their houses and are biking towards each other. Bryan started
out first, and has already gone 5 miles. He bikes at a constant speed of 3 miles per hour.
Yuan just left, and rides at 4 miles per hour. When the boys meet halfway between their
houses, they will continue to the park together. How long will that take? How far will each
boy have ridden?
Answers
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.
A store used to sell an MP3 for $72which is 50% more than the wholesale cost. At a special holiday sale, the price of the MP3 was 20% less than the wholesale cost. What was the special sale price of the MP3?
Answers
Answer:
$115.2
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
= 144-28.8
=$115.2
Which equation best represents the line? (4 points)
a
y = 1 over 3.x − 1
b
y = 3x − 1
c
y = −x + 1 over 3.
d
y = 3x + 1
Answers
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

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

In a paint factory, an old conveyer line has filled 12 barrels of paint, and is filling more at a rate of 4 barrels per minute. A worker just switched on a newer line that can fill 10 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How long will that take? How many barrels will each line have filled?
Answers
Answer:
Take 2 minutesEach line would have filled 20 barrelsStep-by-step explanation:
First line is filling at 4 barrels a minute and has already filled 12
Second line is filling at 10 barrels a minute.
Assume the time taken to be equal is x:
12 + 4x = 10x
12 = 10x - 4x
6x = 12
x = 12/6
x = 2 minutes
Each barrel would have filled:
= 10x
= 10 * 2
= 20 barrels
