The graph shows how the mass of copper
changes as the volume of the element changes
and the density remains constant.
*picture*
Which of these bests represents the rate of the
change in the mass of copper with respect to the
volume?
a.4/33 g/cm^3
b.19/41 g/cm^3
c.8 1/4 g/cm^3
d.4 4/7 g/cm^3
Answer: 8 1/4g/cm³
Step-by-step explanation:
Given the graph :
The rate of change in the mass of copper with respect to volume :
To obtain this, we find the slope or gradient of the graph:
Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angled triangle on the anybpart of the line of best fit:
y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2
(y2 - y1) / (x2 - x1)
= (40 -16) / (4.75 - 2)
= 24 / 2.75
= 2400/275
= 8.727 g/cm^3
Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³

A certain video game console uses 154 watt-hours of energy each hour.
The console used 276 hours last year.
How many watt-hours of energy did the console use?
Use any method to solve this problem. You must show all your work.
Then, explain your reasoning and the steps you took to solve the problem.
Answer:
42,504 watts
Step-by-step explanation:
154x276hours=42,504watts
Answer:
42504
Step-by-step explanation:
As it uses 154 watt-hours per hour, in 276 hours, it would use 42504 as we would multiply the energy usage by the amount of hours used:
154 watt-hours = 1 hour
276 hours = 42504 watt-hours
276*154 = 42504

Subtraction property of equality (a)
The answer is A because the subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.

Identify the slope and y-intercept of this graph.
•
slope = 2, y-intercept = 1
slope = 2, y-intercept = 1
slope = 2, y-intercept = -1
slope = -2, y-intercept = -1
Identify the slope and y-intercept of this graph.
Answer:
Step-by-step explanation:
Looking at the first graph, we see that if x increases from 0 to 1, y decreases from 2 to 0:
m = rise / run = -2/1 = -2
Arbitrarily choose the reference point (1, 0).
Then y = mx + b becomes 0 = -2(1) + b, where b is the y-intercept.
Then b = 2, and the desired equation is
y = -2x + 2
Answer:
15. slope=-2
y-intercept=2
16. slope=2
y-intercept=1

The formula for the volume, v, of a cone having the radius,r, and the height is shown below v=1/2 πr2h write the formula to calculate the height, h
Answer:
h= 2v / πr²
Step-by-step explanation:
height of a cone is twice of it's volume divided by π and square of radius
Step-by-step explanation:
v = 1/2 πr²h
v / 1/2 πr² = 1/2 πr²h / 1/2 πr² (Divide both sides of the equation by 1/2 πr² to find the formula for height (h).
v / 1/2 πr² = h or h = 2v / πr²

Find an expression which represents the sum of (6x – 4) and (-2x + 5) in simplest terms.
Answer:
5
Step-by-step explanation:
because if you add -2x and 5 you would get 3 also if you subtract 6x-4 you would get 2x so add 2x and 3x then you would get five

4. Find the value of x. (x + 23) (x + 13)
x = 27°
Step-by-step explanation:Hi there !
x + 13 + x + 23 = 90
2x = 90 - (13+23)
2x = 90 - 36
2x = 54
x = 54 : 2
x = 27°

- WHATS THE NEGATIVE SLOPE??
- FIND M’S SLOPE
PLEASEEESWEEEEEEEEEEE⚠️
Answer:
Question 1: The negative slope is line j.
Question 2: M's Slope is 1/2.
Step-by-step explanation:
Question 1:
Way 1:
The negative slope is line j because it moves from left to right where the y points decrease while x is increasing.
Way 2:
Finding the slope also finds if it has a negative or a positive slope.
Line j has points (-1,3) and (0,0).
To solve for slope, you have to do (y2-y1)/(x2-x1).
To substitute the values, it gets to (0-3)/(0-(-1)).
To simplify that, it gets to -3/(0+1) which equals to -3/1. -3/1 in other words is -3.
Since the slope is a negative number, it has a negative slope.
Question 2:
To find the slope of line m, you have to find two points first.
The two points there are is (4,2) and (0,0).
Then you have to use the equation (y2-y1)/(x2-x1).
Once you find the numbers, you plug it into the equation getting (0-2)/(0-4).
To simplify that it gets to -2/-4. That equals -1/-2 once simplifying the fraction.
Since there are negatives in both numerator and denominator, the negative sign gets removed and it becomes 1/2.
Therefore, the slope for line M is 1/2.

= 4
θ =
arctan( ΔY )
ΔX
= 75.963756532074°
ΔX = 4 – 2 = 2
ΔY = 16 – 8 = 8
Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353
