Stacey is going rock climbing.She stats 2.5 kilometers up a cliff , climbes up 7 more kilometerd and then climbs all the way down to the bottom of the cliff. What is the total distance of her climb ?
Answer:
19 kilometers
Step-by-step explanation:
2.5 kilometers + 7kilometers
= 9.5 kilometers
+ the additional 9.5 for the trip down
=19 kilometers in total
Stacey total distance for climbing was 16.5 km
Stacey started 2.5 km up the cliff so this 2.5km is not counted as she started at that point.
She then climbed 7 km up the cliff.
After that she climbs back down to the bottom of the cliff. This time she climbs both the 7km she climbed previously, and the 2.5km she hadn't climbed before.
Tracy total climbing distance is:
= Distance climbed up + Distance climbed down
= 7 + ( 7 + 2.5)
= 7 + 9.5
= 16.5 km
In conclusion, Stacey climbed 16.5 km in total.

Your phone plan charges you an initial fee, and then a certain amount depending on the amount of data you use. They send you periodic updates of your usage and your current bill cost. After using 3 GB of data, you owe $30. After 5 GB of data, you owe $40. What is the cost per GB of data?
Answer:
$5
Step-by-step explanation:
Let
x = initial fee
y = fees depending on the amount of data he use
After using 3 GB of data , he owes $30.
After using 5 GB of data , he owes $40.
The equations are
x + 3y = 30 (1)
x + 5y = 40 (2)
Subtract (1) from (2) to eliminate x
5y - 3y = 40 - 30
2y = 10
Divide both sides by 2
y = 10/2
y = $5
Substitute y = 5 into (1)
x + 3y = 30
x + 3(5) = 30
x + 15 = 30
x = 30 - 15
x = $15
Cost per GB of data = $5

Answer: you have: C(X)=3x+2.00
x=number of minutes
Pay attention to the y=mx+b form where m=slope-->>
3x is the slope...
so it's 3(times the number of minutes) <<---or (x)
This means that the slope is 3, or the fancy way of saying it-->>"rate of change."
The rate of change of the cost of the taxi ride is $3.00 per minute.

what is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?
Answer:
y=3x+5
Step-by-step explanation:
For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.
First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:
y-(2)=3(x+1)
y-2=3x+3
y=3x+5
Check:
(2)=3(-1)+5
2=-3+5
2=2
1. In the diagram below, if m angle1=79^ , find the measure of each numbered angle.
The measure of angles ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.
We have been given that m angle ∠1 = 79°,
To determine the measure of each numbered angle.
As per the property supplementary angles,
m∠1 + m ∠2 = 180°
79° + m ∠2 = 180°
m ∠2 = 180° - 79°
m ∠2 = 101°
If a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
∠1 = ∠4 = 79°
∠2 = ∠3 = 101°
∠2 = ∠6 = 101°
∠4 = ∠5 = 79°
∠5 = ∠8 = 79°
∠6 = ∠7 = 101°
Thus, the measure of angles ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

Answer:
40 degrees
Step-by-step explanation:
There are parallel lines and a transversal. That means that angle a and b are congruent due to corresponding angles theorem.
5x-5=3x+13
Move the variables on one side and numbers on the other. 2x=18
Finally, x=9 And then after you plug it in, your final answer for angle b is 40 degrees.
Answer:
Step-by-step explanation:
Well both angles are the same because the lines are parallel and then there is a line going through them so <A = <B meaning
5x-5=3x+13 and then you solve
5x - 3x = 13 + 5
2x = 18
x = 9

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites
Answer:
h = 59 hours
Step-by-step explanation:
Total earnings = fixed charge + variable charge
Fixed charge = $65
Variable charge = $15h
Where, h = number of hours
Total earnings = $950
Total earnings = fixed charge + variable charge
950 = 65 + 15h
Subtract 65 from both sides
950 - 65 = 65 + 15h - 65
885 = 15h
Divide both sides by 15
h = 885 / 15
= 59
h = 59 hours

The expression represents the second consecutive odd integer is X + 2
and for the third consecutive odd integer is X + 4.
What are integers?All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a set of integers is formed.
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
Given One example of consecutive odd integers would be 3, 5, 7, 9, ...
the difference between 2 consecutive numbers is
5 - 3 = 2
when X is the first odd integer,
the second consecutive odd integer is X + 2
difference between 3rd and first digit is
7 - 3 = 4
the third consecutive odd integer is X + 4
Hence adding the consecutive even numbers to the first digit of odd numbers gives the consecutive odd numbers.
