mary thinks the triangle is equilateral. how would you support or dispute her conjecture?
Answers
Answer:
Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.
Step-by-step explanation:
An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.

Answers
Answer:
70/100 or 7/10
Step-by-step explanation:
As a percentage 70 percent is 70%.
As a fraction because 70 is out of 100 it would obviously be 70/100 but you can simplify to 7/10 and it is still equal to 70%

Complete question;
A booster club paid for pizzas for an end of season party. They paid $13 for each pepperoni pizza and $11 for each plain pizza. The club bought a
total of 18 pizzas for the party and paid a total of $212.
Drag and drop the numbers to the boxes to create an equation which models this situation if x = the number of pepperoni pizzas and y = the number of plain pizzas bought.
Answer:
13x + 11y = 212
Step-by-step explanation:
They bought 2 different recipe of pizza. The first is the pepperoni pizza and the second kind is the plain pizza. The pepperoni pizza cost $13 each while the plain Pizza cost $11 each. The total number of pizza bought is 18 in number.
The total cost of the pizza is also $212.
number of pizza bought = 18
total cost of pizza = $212
x = the number of pepperoni pizzas
y = the number of plain pizzas
The number of pepperoni pizzas multiply by the cost for each will give the cost of the pepperoni pizzas. This same method is applied to get the cost of the plain pizzas.
Therefore, adding the individual cost of the kinds of pizza will give the total cost of the pizzas.
13x + 11y = 212

find the middle, in this case, it's two numbers (10 and 12)
3 6 are on the left, find the middle between them; 3+6/2

Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope intercept form.
Answers
slope = 1/2, y intercept = 3
==============================================================
Work Shown:
Pick any two points you want on the line.
I'll pick the two points (0,3) which is the y intercept and also the point (2,4).
------
Find the slope of the line through (x1,y1) = (0,3) and (x2,y2) = (2,4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 3)/(2 - 0)
m = 1/2 is the slope
slope = rise/run = 1/2
rise/run = 1/2 means rise = 1 and run = 2.
This means we go up 1 unit each time we move to the right 2 units.
-----
Since the slope is m = 1/2 and the y intercept is b = 3, we can say
y = mx+b
y = (1/2)x+3
this is the same as y = 0.5x+3 since 1/2 = 0.5
Can someone please help me with the slope?
Answers
Answer:
1/2
Step-by-step explanation:
For each two units that this line moves to the right, it rises one. This means that it has a slope of 1/2. Hope this helps!

Their measures cannot be equal.
Answers
Answer: the sum of their measures is 180 degrees
Step-by-step explanation:
I just got it right
The angles R T S and Q T P are vertically opposite angles. So that they always have equal measures.
Circle :In given circle, T is center of circle .
and RP and SQ are diameter of circle which are intersecting at center T.
The diagram of circle is attached below.
In the diagram of circle, Angles R T S and Q T P are congruent.
So that, [tex]\angle RTS=\angle QTP\\\\[/tex]
Since, both diameter are crossing each other.
So that, Angles R T S and Q T P are vertically opposite angles.

Which equation models a line that is perpendicular to y = x - 1 and goes through the point (5,4)
Answers
Answer:
y = - x + 9
Step-by-step explanation:
Because the line is perpendicular, the slope with be the opposite reciprocal. So, if the slope is 1 as in the equation y = x - 1, the opposite reciprocal is -1.
So the equation that is perpendicular will look like this so far:
y = -x + b (b represents our y-intercept that we have not found yet)
Now we will find the y-intercept. We can find it by substituting the coordinates (5,4) as x and y into the equation right above ^^.
So, 4 = -(5) +b or 4 = -5 + b
Add 5 to both sides to isolate b on the right side. b = 9
Therefore, the y-intercept is 9.
Now we have found everything we need for the equation, which is
y = - x + 9

A right circular solid cone of base radius 42cm and height 84cm has the same volume as a solid cylinder of height 112cm find the radius of the cylinder
Answers
Answer:
21 cm
Step-by-step explanation:
Volume of cone is given by [tex]1/3(\pi r^2h)[/tex]
volume of cylinder is given by [tex]\pi r^2h[/tex]
where r is the radius of base and h is the height
_________________________________
For cone
radius = 42cm
height = 84
volume = [tex]1/3(\pi *42^2*84)[/tex] (1)
________________________________
For cone
radius = to find let it be r
height =112
volume = [tex]\pi *r^2*112[/tex] (2)
_______________________________________
since , volume of both solid are same
thus, equation 1 = equation 2
[tex]1/3(\pi *42^2*84) = \pi *r^2*112\\=> r^2 = 1/3((\pi *42^2*84) / 112*\pi \\=> r^2 = 1/3(42*42*84/112) = 441\\=> r = \sqrt{441} \\=> r = 21[/tex]
Thus, radius of cylinder is 21 cm

Jeremy’s bank account started at a balance of $124 this week. Since then, he wrote a check, which decreased his balance by $147. Jeremy was then charged an overdraft fee, decreasing his balance by $32. Finally, he deposited a paycheck, which increased his balance by $567. What is Jeremy’s ending balance after these transactions, in dollars?
Answers
Answer:
$512
Step-by-step explanation:
His bank account started at a balance of $124.
He wrote a check, which decreased his balance by $147. His new balance is:
124 - 147 = -$23
Jeremy was then charged an overdraft fee, decreasing his balance by $32. That is:
-23 - 32 = -$55
He deposited a paycheck, which increased his balance by $567. His account balance will become:
-55 + 567 = $512
His account balance after those transactions is $512.
The final velocity, V, of an object under constant acceleration can be found using the formula v2=v2+2as, where v is the initial velocity (in meters per second), a is acceleration (in meters per second), and s is the distance (in meters). What is the formula solved for a?
Answers
Answer: a = (V^2 - v^2)/2s
Step-by-step explanation:
The equation for the final velocity is:
V^2 = v^2 + 2*a*s
where V is the final velocity, v is the initial velocity, a is the acceleration and s is the distance.
Now, we want to solve this formula for a, this would mean isolate a in one side of the equation, this is pretty simple, first we pass subtract v^2 in both sides.
V^2 - v^2 = v^2 + 2*a*s - v^2
V^2 - v^2 = 2*a*s
now we can divide by 2*s in both sides:
(V^2 - v^2)/2s = 2*a*s/2s = a
a = (V^2 - v^2)/2s
