Soil is often considered an abiotic factor since it is mostly made up of small particles of rock (sand and clay) mixed with decomposed plants and animals. Plants use their roots to get water and nutrients from the soil.
Also just a tip, make sure to put it in the correct category next time cause someone can report it :(
Anyways hope this helps!! :D
Megan budgeted $300 for her shopping trip. She spent $61.50 on jewelry at Revin Jewelry. What percent of her budget did she spend on jewelry? (write the exact percentage)
Answer:
20.5%
Step-by-step explanation:
Here, we want to calculate the % spent on Jewelry
To get that, we divide the amount spent on Jewelry by the total budget and multiply by 100
That will be;
61.5/300 * 100% = 20.5%

You are comparing 3 different cell phone plans to see which is the cheapest:
Plan A costs a basic fee of $30 per month and $10 for every GB of data used
Try writing each plan as an
equation in y = mx + b form where
Plan B costs a basic fee of $80 per month with unlimited data
=GBs used and y total cost.
Plan C costs a basic fee of $50 per month and $5 for every GB of data used
You're looking to replace the m and
b in the equation. For Plan A, where
a) Write an equation for each plan that calculates the total cost (y) in terms of GB of data used (x) would the $30 go? Where would
the
Plan A:
Plan B:
Plan C:
$10 go?
b) Graph each plan on the following set of axes.
Cell Phone Plan Costs
Cost
100
c) When does Plan A cost the same as
Plan C?
80
60
d) Which plan is best if you only use 0-
4 GBs of data a month?
40:
20.
GBs of
8 10 data used
4
6
e) When does Plan B become the best
deal?
Answer:
Plan A equation: y = 10x + 30
Plan B equation: y = x + 80
Plan C equation: y = 5x + 50
Plan A costs the same as Plan C in 4 months
Plan A is the better option if you use 0 - 4 GBs of data each month
Plan B becomes the better deal when 8 months pass
Step-by-step explanation:
When does Plan A cost the same as Plan C?
Set the equations equal to each other (the cost) and solve for x (time in months)
10x + 30 = 5x + 50
5x = 20
x = 4 months
Which plan is best if you only use 0-4 GBs of data a month?
Test the maximum and minimum values to check which plan costs less
At 0 GBs of data used per month
Plan A: y = 0 + $ 30 = $30 total
Plan B: y = 0 +$80 = $80 total
Plan C: y = 0 + $50 = $50 total
At 4 GBs of data used per month
Plan A: y = $ 40 + $ 30 = $ 70
Plan B: y = $ 4 + $ 80 = $ 84
Plan C: y = $ 20 + $ 50 = $ 70
Comparing the plans at maximum and minimum amount of GBs used, only one plan has the lowest cost overall. Even though Plan C is the same price at 4 GBs as Plan A, when you use 0 GBs you will end up paying more in Plan C than Plan A. Therefore, Plan A is the better option
When does Plan B become the best deal?
When you plot the different Plans on a graph, the slope intercept of x = 7.5 (rounded up to 8) yields the lowest cost for plan B

According to the scatterplot below, about how many commercials could one expect to see in 30 minutes of television programming?
Chrystelle's mother is 1 2/3ft taller than Chrystelle. If
Chrystelle is 3 1/2 ft tall, how tall is her mother?
Answer:
4 5/6 feet.
Step-by-step explanation:
The least common multiple for 2 and 3 is 6, so if we change the denominators to 6, we get Chrystelle's height as 3 3/6, and her mother is 1 4/6 ft taller than her.
3 3/6 + 1 4/6= ?
(Written as an Improper fraction)
21/6 + 10/6 = 31/6
31/6 = 4 5/6.
I hope this helps!
Answer:
first make it so the denominator is the same on bothers sides. a common denominator for both is 6 so
Chrystelle mom: 1 2/3 taller. multiply the fraction by 2/2 so 1 4/6
chrystelle: 3 1/2 feet tall. multiply the fraction by 3/3 so 3 3/6
now just add to figure out so
3 3/6 + 1 4/6 = 4 7/6 which simplifies down to 5 1/6
so chrystelles mom is 5 1/6 feet tall
José made these grades on tests: 78, 88, 98. Without doing any computing, what is his average?
Answer:
88 is the average
Step-by-step explanation:
78 + 88 + 98 = 264
264 / 3 = 88 ( you divide by the amount of numbers you have, in this case there are three numbers)

Colin buys a car for £28100.
It depreciates at a rate of 4% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answer:
The amount the car will be worth after 6 years is £21,917 and 22 pence
Step-by-step explanation:
The amount for which Colin buys the car, PV = £28,100
The amount by which the car depreciates each year, r = 4%
The number of years after which the value of the car is sought, n = 6 years
The future value, FV, based on an annual depreciation is given as follows;
[tex]FV = PV \times \left ( 1 + \dfrac{r}{100} \right ) ^n[/tex]
Substituting the known values gives;
[tex]FV_6 = 28,000 \times \left ( 1 - \dfrac{4}{100} \right ) ^6 = 21,917.22[/tex]
Therefore, the amount the car will be worth after 6 years, future value FV₆ = £21,917 and 22 pence

Which table represents a linear function?
Answer: table 1.
Step-by-step explanation: This is because the x-axis is going up by 2 and the y-axis is also going up by 2. There is a pattern and when you would graph it, it will be linear as it goes up by the same amount

You were in the car with a family member. You started with 7/10 of a tank of gas, and when you got home you had ⅓. How much gas did you use?
9514 1404 393
Answer:
11/30 of a tank
Step-by-step explanation:
The amount used is the difference between the starting amount and the ending amount:
7/10 -1/3 = 21/30 -10/30 = 11/30 . . . . of the tank
Express y = 3x + 10 using function notation.

LeeAnn earns an annual salary of $50,000 after taxes. Her average expenses per month come to $3,350. If she saves all the money that she doesn't use to pay expenses, how much will she have in savings at the end of the year?
Answer:
$9800
Step-by-step explanation:
Given that:
Annual salary = $50,000
Average monthly expenses = $3350
Average amount spent per annum:
Number of months in a year = 12
12 * $3350 = $40,200
Since, all amount not used as expenses is saved :
Total amount saved = $50,000 - $40,200
Total amount saved = $9800
Answer:
$9,800, just took the test
Step-by-step explanation:
took the test

URGENT!!! Can someone help me with this? It’s volume of cones!!!
Answer:
1232 m^3 to nearest whole number.
Step-by-step explanation:
The volume of a cone = 1/3 π r^2 h where r = radius of base and h = height.
The radius of the base = 1/2 * 14 = 7m.
The height can be found by using the Pythagoras theorem:
25^2 = h^2 + 7^2
h^2 = 625 - 49 = 576
h = √576 = 24m
So the volume = 1/3 π * 7^2 * 24
= 1231.504 m^3.
A cherry pie has a 16 inch diameter. What is its approximate area? Round to the nearest hundredth. (Use 3.14 for π)
Answer:
200
Step-by-step explanation:
Formula to find the area: πr²
First, find the radius: 16 ÷ 2 = 8
The radius is 8. So...
= 3.14 (8²)
= 3.14 × 64
= 200.96
Rounded to the nearest hundredth: 200
Answer:
200.96
Step-by-step explanation:
A=3.14r^2(formula for area of a circle)
r=16/2=8
r=8
A=3.14*8^2=200.96

Find the distance between C(-8,-5) and D(-2,3).
Find the midpoint of CD.
Answer:
10 units and (- 5, - 1 )
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(- 8, - 5) and (x₂, y₂ ) = D(- 2, 3)
d = [tex]\sqrt{(-2+8)^2+(3+5)^2}[/tex]
= [tex]\sqrt{6^2+8^2}[/tex]
= [tex]\sqrt{36+64}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
Calculate the midpoint using the midpoint formula
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
= [tex]\frac{-8-2}{2}[/tex], [tex]\frac{-5+3}{2}[/tex] )
= [tex]\frac{-10}{2}[/tex], [tex]\frac{-2}{2}[/tex] )
= (- 5, - 1 )

Answer:
h = 1/5
Step-by-step explanation:
The formula to find the volume of this prism is b × w × h (base × width × height). Since you are given the volume, you can divide the volume by the other two dimensions to find the height.
V = b × w × h
1/100 = 1/4 × 1/5 × h
1/100 ÷ 1/4 ÷ 1/5 = h
h = 1/5
