[[Please explain]] The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters. Which equation relates the mass of the object, m, and the length of the spring, s?
O s=3/10m
O s=10/3m
O s=3/10s
O s=1/30s
Answer:
The required equation is [tex]s =\frac{3}{10} m[/tex]
Step-by-step explanation:
Given: The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.
To find : Which equation relates the mass of the object, m, and the length of the spring, s?
Solution :
Let the mass of the object m,
Length of the spring s,
When a 30-gram object is attached, the spring stretches 9 centimeters.
i.e, the times length of the object is attached to spring is The length of a spring varies directly with the mass of an object that is attached to it.
According to question,
i.e, length of the spring is 3 by 10 times the mass of the object.
Therefore, The required equation is
which expression has a value of 6 when x=2 and y=4?
Let's verify all the options to the question. Clue given: x = 2, y = 4
Option A:
(x² + 8) ÷ y - 2
=> (2² + 8) ÷ 4 - 2
=> (4 + 8) ÷ 4 - 2
=> 12 ÷ 4 - 2
=> 3 - 2
=> 1 ≠ 6
This answer does not equal 6.
Option B:
(x² + 8) ÷ (y - 2)
=> (2² + 8) ÷ (4 - 2)
=> (4 + 8) ÷ (4 - 2)
=> 12 ÷ 2
=> 6 = 6
This answer is correct as 6 = 6.
Option C:
x² + 8 ÷ (y - 2)
=> 2² + 8 ÷ (4 - 2)
=> 4 + 8 ÷ 2
=> 4 + 4
=> 8 ≠ 6
This answer does not equal 6.
Option D:
x² + 8 ÷ y - 2
=> 4 + 8 ÷ 4 - 2
=> 4 + 2 - 2
=> 4 ≠ 6
This answer does not equal 6.
So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

what is the slope on an equation
Answer:
Formula
Slope of a line
Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).
Step-by-step explanation:
slope= dy/dx
=y2-y1/x2-x1
Kala invested $8000 in a fund for 6 years and was paid simple interest. The total interest that she received on the investment was $2400. As a percentage, what was the annual interest rate of her investment?
Answer:

An auto insurance company pays 12%
commission to its agents for each new insurance policy they sell. How much commision does an agent make on a $1,000 policy?
Answer:
$120.00 commission
Step-by-step explanation:
1000 X 0.12 = 120
19= X+5*Z-12
what is X and Z?
Answer:
X = -5Z + 31
Step-by-step explanation:
Subtract 5Z5Z from both sides.
19 - 5Z = X - 12
19 − 5Z = X − 12
2 Add 1212 to both sides.
19 - 5Z + 12= X
19 − 5Z + 12= X
3 Simplify 19-5Z+1219−5Z+12 to -5Z+31−5Z+31.
-5Z + 31 = X
−5Z + 31 = X
4 Switch sides.
X = -5Z + 31
X = −5Z + 31
Answer:
19=x+5*z-12
19+12=x+5*z
31=x+5*z
then x=26 z=1

Answer 3-12 please, thank you!
Done the first two but i dont know how to do the mean of it
To find mean:
1) Add up all data values to get the sum
2) Count the number of values in your data set
3) Divide the sum by the count
First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.
4 x 2 = 8
5 x 10 = 50
6 x 18 = 108
7 x 14 = 98
8 x 6 = 48
8 + 50 + 108 + 98 + 48 = 312 total number of peas
2 + 10 + 18 + 14 + 6 = 50
312 / 50 = 6.24 peas per pod
So in our example the mean number of peas in a pod is 6.24.
I hope this helps! :)

In your own words, explain to me what is absolute value? . Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.
Answer:
Absolute Value Is Pretty Simple Actually In Middle School Math. Absolute Value Refers To The Numerical Difference From 0 To The Integer. To Find Absolute Value All We Have To Do Is Find The Difference From 0 To The Number. For Example -9 The Absolute Value Is 9 Because On A Numberline There Are 9 Spaces Between 0 and -9 and +6 Is 6.
(This Is How We Learned It In Middle School There Is A Higher Level To This Tho)

Which size bottle of ketchup is the best deal with the lowest unit price?
Answer:
I think the best deal would be 14 oz

2x - 8x + 1 = 49
this seriously makes no sense
Answer:
x = -8
Step-by-step explanation:
2x - 8x + 1 = 49
⇒ 2x - 8x = 49 - 1
⇒ -6x = 48
⇒ x = [tex]\frac{48}{-6}[/tex]
= -8
Answer:
X = -8
Step-by-step explanation:
Add similar elements: 2x-8=6x
-6x+1=49
Subtract 1 from both sides:
-6x+1 -1 =49 - 1
Simplify:
-6x=48
Divide both sides by -6
-6x /-6= 48 /6
Which then gets you the answer up top!
