What does the statement “ The shortest distance between two points is the straight line between them” have to do with the Triangle Inequality Conjecture?
Do not answer this with one, none, or a ridiculous response please... this is serious
Answer:
https://geometryhelp.net/triangle-inequality-theorem/
Step-by-step explanation:
This is from that site. Visit it and you may find what you're looking for.
If we want to go from point A to point B, getting there through any intermediate point C, which is not on the straight line between A and B, is going to be longer. This should seem intuitively correct. But we will prove it formally.
Where do triangles come into this? Imagine that the line AB is a side of a triangle, ΔABC. Going from A to B is the straight, short way. Going there by first going to another point, C (which is the side AC) and then from C to B (which is the side CB) is going to be longer.
1) A cyclist travels a distance of 90 miles in 5 hours. What
was her average speed?
2) How far along a motorway would you travel if you drove at
70 mph for 4 hours?
3) I drive to Bude in Cornwall from Sheffield in about 6
hours. The distance from Sheffield to Bude is 315 miles.
What is my average speed?
4) The distance from Leeds to London is 210 miles. The train
travels at an average speed of 90 mph. If I catch the 9.30 am
train in London, at what time should I expect to arrive in
Leeds?
5) How long will an athlete take to run 2000 m at an average
speed of 4 metres per second?
6) The distance between Sheffield and Land’s End is 420
miles.
a) What is the average speed of a journey from Sheffield to
Land’s End that takes 8 hours 45 minutes?
b) If Sam covered the distance at an average speed of 63
mph, how long would it take him?
Answer:
Step-by-step explanation: Speed is distance an object travelled per unit time.
It is represented by letter v and can assume various units.
1) [tex]v=\frac{distance}{time}=\frac{d}{t}[/tex]
[tex]v=\frac{90}{5}[/tex]
v = 18 miles per hour
Her average speed is 18 mph.
2) Rearraging formula for distance:
d = v.t
d = 70 * 4
d = 280 miles
You would travel 280 miles.
3) [tex]v=\frac{d}{t}[/tex]
[tex]v=\frac{315}{6}[/tex]
v = 52.5 mph
My average speed is 52.5 mph.
4) Rearranging formula to determine time:
[tex]t=\frac{d}{v}[/tex]
[tex]t=\frac{210}{90}[/tex]
t = 2.34 hours
It will take 2 hours and half to arrive in Leeds. So, we will be expected to arrive at 12:04.
5) The unit change but the way of calculating time is the same.
[tex]t=\frac{2000}{4}[/tex]
t = 500 s
or t = 8.34 minutes
It will take, for an athlete to run 2000m, 8.34 minutes.
6) a) All units must match, so for a speed in mph:
45 minutes is 0.75 hours. Total time is 8.75 hours.
[tex]v=\frac{420}{8.75}[/tex]
v = 560 mph
The average speed is 560 mph.
b) [tex]t=\frac{d}{v}[/tex]
[tex]t=\frac{420}{63}[/tex]
t = 6.67 hours
Sam will take 6.67 hours to covered the distance.

Peggi gave each of her 4 friends some bows to put in a gift bag. Her Mommie gave each friend 6 more bows. The bags contained a total of 72 bows. How many bows did each friend get?
Answer:
18 I believe
Step-by-step explanation:
72/4
Answer:
each friend got 18 bows
to find how many bows each friend got;
total ÷ amount of friends=
72÷4 = 18
(to find amount she gave her friends individually;
amount each friend got - amount her mom gave them
= 18-6=12)

Step-by-step explanation:
In the first blank, write in 7 for x, and in the second blank, write in 8 for y. Then perform the indicated multiplication and addition.
12.3(7) + 11.5(8), or
86.1 + 92 = 178.1
What is the domain of the function f(x)= x^2-16/x-4
Answer:
Step-by-step explanation:
this is a rational function thus the domain is all real numbers except the values which make zero to denominator
hence x-4=0 ;x=4
the domain of that function is R- {4}
Matthew makes a drink using lemonade and orange juice.
210ml of his drink was lemonade
140ml of his drink was orange juice
Rosie makes more of the drink for a party using the same ratio of lemonade to orange juice.
Rosie uses 6 litres of lemonade.
How much orange juice does Rosie use?
Answer: 4
Step-by-step explanation:
Matthew makes a drink using lemonade and orange juice.
210ml of his drink was lemonade
140ml of his drink was orange juice
Based on the above, we can see that the ratio of lemonade to orange juice is 3:2. 70 is a common factor to 210 and 140. 210/70 = 3 while 140/70 = 2.
Therefore, since Rosie uses 6 litres of lemonade, the amount of orange juice that Rosie use will be:
= 6 × 3/2
= 4
Rosie needs 4 litres of orange juice.
The difference between two numbers is 78. Six times the smaller is equal to 7 more than the larger. What are the numbers?
Answer: x=95 and y=17
Step-by-step explanation:
X-y=78
6y=7+x
6y-7=x
6y-7-y=78
5y-7=78
5y=85
y=17
x-17=78
x=78+17
x=95
Answer:
x=143
y=25
thus ur two numbers are 143 and 25

A server at a restaurant works 5 hours on a weekday and 8 hours on a weekend day. Use the expression to find the number of hours the server works on 4 weekdays and 2 weekend days.
Answer: 36 hours
Step-by-step explanation:
t = total hours
t = 5d + 8w
t = 5(4) + 8(2)
t = 20 + 16
t = 36

The income and the costs of a company are given by the equations below, where x is the number of units sold, in hundreds, and y is the total dollar amount, in thousands.
Income: y = -0.5x2 + 6x + 90
Costs: y = 2.5x + 30
Determine which of the following would be a viable solution for the number of units sold that would cause the income and the costs to be the same.
a. 700 units sold and a value of $47,500
b. 800 units sold and a value of $32,800
c. 1,000 units sold and a value of $25,000
d. 1,500 units sold and a value of $67,500
Answer:
D
Step-by-step explanation:
The income is given by:
[tex]y=-0.5x^2+6x+90[/tex]
And the costs are given by:
[tex]y=2.5x+30[/tex]
Where x is the number of units sold, in hundreds, and y is the total dollar amount, in thousands.
We want to find a viable solution for the number of units sold that would cause the income and cost to be the same.
So, we can set the two equations equal to each other and solve for x. Therefore:
[tex]-0.5x^2+6x+90=2.5x+30[/tex]
Subtract 2.5x and 30 from both sides:
[tex]-0.5x^2+3.5x+60=0[/tex]
Remove the decimals and the negative of the leading coefficient by multiply both sides by -2:
[tex]x^2-7x-120=0[/tex]
Factor. We can use -15 and 8. So:
[tex](x-15)(x+8)=0[/tex]
Zero Product Property:
[tex]x=15 \text{ or } x=-8[/tex]
The answer must be positive since we cannot sell negative units.
So, the value of x is:
[tex]x=15\text{ or } 1,500 \text{ units}[/tex]
Then using either equation, the value will be:
[tex]2.5(15)+30=67.5=\$67,500[/tex]
Our answer is D.
Answer:
d. 1,500 units sold and a value of $67,500

There will be 6 people at Eli's cake party. You want to bake enough cake so that each person you feed will eat at least 1/5 of the cake. What is the minimum number of cakes to bake?
Please put the procedure with operations used. :(
Answer: 2 cakes.
Step-by-step explanation:
There will be a total number of 6 people at Eli's cake party.
You want that each one of these 6 people to eat at least 1/5 of a cake.
Then you need to make, at least, 6 times 1/5 of a cake.
This is equal to:
6*(1/5) of a cake = 6/5 of a cake.
And we can rewrite this as:
(6/5) of a cake = (5 + 1)/5 of a cake = (5/5 + 1/5) of a cake = 1 cake + 1/5 of a cake.
But you can not bake only 1/5 of a cake, we need whole numbers.
Then we need to round up to the next whole number, which is 2.
This means that you need to bake at least 2 cakes.
