The ratio of skiers to snowboarders is 5 to 2. If 210 skiers rode the chairlift in the last hour, how many snowboarders rode the chairlift during that same time?
[A] Write a proportion that is defined by this situation.
[B] Explain how the cross product is used to solve the problem.
[C] Answer the question.
Answer:
84
Step-by-step explanation:
5/2 for every 2.5 skiers one snowboarder rides
[A] 2.5 skiers to one snowboarder
[B] [tex]\frac{1}{2.5} = \frac{?}{210}[/tex]
210=2.5*x divide both sides by 2.5
x=84
[C] 84 snowboarders rode at the same time as 210 skiers

Solve for the value of s.
HELP PLS NOW 20 POINTS
Answer:
15
Step-by-step explanation:
82 + (7s - 7) = 180
- subtract 82 from both sides
7s - 7 = 98
- add 7 to both sides
7s = 105
- divide both sides by 7
s = 15

Step-by-step explanation:
3a+ 6 = 15, 3a = 9, a+ 2= 5, 1/3a =1
are any of these equation equivalent to one another if so, which ones? Explain tou reason
Given parameters:
Find if any of the equations are the equivalent;
3a+ 6 = 15
3a = 9
a+ 2= 5
[tex]\frac{1}{3a}[/tex] =1
To find which of the equations are equivalent to one another, let us solve them first. The ones with the same solution are definitely equivalent.
(i) 3a+ 6 = 15
3a = 15 - 6
3a = 9
a = 3
(II) 3a = 9
a = 3
(III) a+ 2= 5
a = 5-2
a = 3
(IV) [tex]\frac{1}{3a}[/tex] =1
1 = 3a
a = [tex]\frac{1}{3}[/tex]
We clearly see that the first three equations are equivalent.

A runner runs at an average speed of 5 m/s for 50 seconds.
How far did the runner run in metres?
Answer:
He has ran 250 metres.
Step-by-step explanation:
Since he runs 5 meters per second, you would obviously multiply 50 times 5, which is 250.
Answer:
250 meters
If you do 5 x 50 you will get how far the runner ran because I mean that's how averages work, I really hope this helped!

In a city the distance between the libary and the police station is 3 miles less than than the distance between the police station and fire station the distance between the libary and police station is 5 miles how far apart are the police station and the fire station
Answer:
8 miles
Step-by-step explanation:
Given
Represent the police station with P, Library with L; Fire station with F
The first statement can be represented as:
[tex]L - P = P - F - 3[/tex]
The second can be represented as:
[tex]L - P = 5[/tex]
Required
Determine the distance between the police station and the fire station (P - F)
[tex]L - P = P - F - 3[/tex] --- (1)
[tex]L - P = 5[/tex] --- (2)
Substitute 5 for L - P in (1)
[tex]5 = P - F - 3[/tex]
Add 3 to both sides
[tex]3 +5 = P - F - 3 + 3[/tex]
[tex]3 +5 = P - F[/tex]
[tex]8= P - F[/tex]
[tex]P - F = 8[/tex]

Scott is making a dip that has 3 5 of a teaspoon of garlic for every 1 2 of a teaspoon of hot sauce. What is the unit rate of garlic to hot sauce in the dip? 1 3 5 teaspoons of garlic per teaspoon of hot sauce 5 6 teaspoon of garlic per teaspoon of hot sauce 1 1 5 teaspoons of garlic per teaspoon of hot sauce 2 3 teaspoon of garlic per teaspoon of hot sauce
Answer:
1/ 1 5 teaspoons of garlic per teaspoon of hot sauce
Step-by-step explanation:
Scott is making a dip that has 3 /5 of a teaspoon of garlic for every 1 /2 of a teaspoon of hot sauce.
3/5 teaspoon of garlic = 1/2 teaspoon of hot sauce
1/2 teaspoon of hot sauce = 3/5 teaspoon of garlic
1 teaspoon of hot sauce =
= 1 × 3/5 ÷ 1/2
= 3/5 ÷ 1/2
= 3/5 × 2/1
= 6/5
= 1 1/5 teaspoon of garlic.
Therefore, the unit rate of garlic to hot sauce in the dip is:
1/ 1 5 teaspoons of garlic per teaspoon of hot sauce

Answer:
y + 8 = 3(x - 8)
Step-by-step explanation:
y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex]) Use point-slope form.
y - (-8) = 3(x - 8) Substitute [tex]y_{1}[/tex]for -8, m for 3, and [tex]x_{1}[/tex] for 8.
y + 8 = 3(x - 8) is the equation.

The value of function f(x) = |x-3| at x=3:
f(3) = 0
Given,
f(x) = |x-3|
Now,
Here the function f(x) is modulus function . Thus the values coming out of the function will be positive .
So,
f(x) = |x-3|
Now we have to substitute the value of x in the function.
f(3) = |3 - 3|
f(3) = |0|
f(3) = 0
Thus the value of function at x = 3 is 0 .

At present, the highest peak of the Appalachian Mountains is 6,684 feet. Millions of years ago, before weathering and erosion had occurred, the highest peak was about 30,000 feet. What is the difference between the highest peak millions of years ago and the highest peak today? Explain how you know your answer is reasonable. Enter the correct numbers in the boxes to show the answer and to complete the explanation.
Answer:
23316ftStep-by-step explanation:
in this problem, we are expected to solve for the change in height of the Appalachian Mountains
given that
the initial height was = 30,000 feet.
the current height is=6,684 feet.
Due to erosion the change/difference in height is give as
change/difference=30000 -6684
change/difference=23316ft
this means that for millions of years ago 23316ft of Appalachian Mountains have been eroded
