Step-by-step explanation:
Determine whether a triangle with the given vertices is a scalene, isosceles, or equilateral triangle. Check all that apply.
9514 1404 393
Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.

Additional comment
It is impossible to specify an equilateral triangle using rational coordinates.
A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences
Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere = [tex]\frac{2}{3}(3.14)(5)^{3}[/tex]
= 261.67 in³
Volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone = [tex]\frac{1}{3}(3.14)(5)^2(17)[/tex]
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³
Solve the equation
x/7= 0.4
Answer:
x = 2.8
Step-by-step explanation:
x/7 = 0.4
multiply both sides by 7
0.4*7 = 2.8
x = 2.8
Answer:
x=2.8
Step-by-step explanation:
one side is divided by seven, lets undo that by multiplying both sides by 7
x/7=0.4

write the recurring decimal 0.25656565656 as a fraction in its simplest form
Answer:
127/495
Step-by-step explanation:
Turning repeating decimals into fractions is a little like surgery: you need to make sure to "cut out" just the right part to let you simplify. In this case, it'd be very nice if we could deal with that repeating 0...565656... part. Let's start by giving our decimal a name:
[tex]x=0.25656...[/tex]
We're gonna split this into two parts: a number we can operate on, and "knife" to make the incision. For both, we'd like the only part to the right of the decimal to be the repeating part. To make our "knife," we'll multiply both sides of the equation by 10:
[tex]10x=2.5656...[/tex]
To make the number we'll be cutting from, we can shift the decimal point by any multiple of two more to the right. I'll keep things simple and stick with 2. This corresponds to multiplying the "knife" equation by 100 on both sides:
[tex]1000x=256.5656...[/tex]
Surgery time! To cut out the repeating bit, we can now just subtract the "knife" equation from the one above:
[tex]1000x-10x=256.5656...-2.5656...\\990x=254[/tex]
And just like that, it's gone! All that's left to do now is divide both sides by 990 and simplify:
[tex]x=254/990=127/495[/tex]

PLS HELP!!! TIMED!!!! I need a step by step explanation of how to divide 93726 by 4!!!!
Answer: the answer is 23434
Step-by-step explanation:first divide 4 by 9 which goes only once, then you would then have 13 which would go only 3 times so 12 minus 13 which is 1 and then goes with 7 to make 17 which means it goes in only 4 times which is 16 meaning the answer is 1 again and then goes with 3 to make 13 and 4 goes in 3 times with 13 to make 12 and then you get 1 which goes into 6 to make 16 and then 4 goes into 16 4 times and then you would get an answer of 23434
The American Quarter Horse is the most popular riding horse in the world. The average weight of an American Quarter Horse at birth is 85 pounds. They grow to a maximum weight of 1300 pounds. Write and solve an inequality to find how many pounds an American Quarter Horse may gain from birth to adulthood.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the average weight of an American Quarter Horse at birth is 85 pounds and that they grow to a maximum weight of 1300 pounds.
The inequality to calculate the amount of pounds that an American Quarter Horse may gain from birth to adulthood will be the difference between it's maximum weight and weight at birth. This will be:
= 1300 - 85.
= 1215 pounds

Find AC please, help is very much appreciated.
Answer:
AC ≈ 67.9
Step-by-step explanation:
15² = 9 (3x + 1 + 9)
225 = 9 (3x + 10)
225 = 27x + 90
135 = 27x
x ≈ 19.29
AC = (3x + 1 + 9)
AC = 3 (19.2857...) + 1 + 9
AC = 57.857... + 1 + 9
AC = 57.857... + 10
AC ≈ 67.9

How do you find the circumference of a circle? Please include an example if you’d like.
Answer:
Step-by-step explanation:
Plug the given value of the diameter into the formula and solve.[2]
Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:
C = πd
C = π x 20
C = 62.8 feet

Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart. How much did they drink altogether?
Answer:
37/56
Step-by-step explanation:
If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually
Total = 3/8 + 2/7
Find the LCM
Total = 3(7)+8(2)/56
Total = (21+16)/56
Total = 37/56
Hence they drank 37/56 of the quartz altogether

m∠T = ?
URGENT HELP
Answer:
105
Step-by-step explanation:
Hello There!
(Let x = angle T)
if you didn't know an exterior angle of a triangle is equal to its two opposite interior angles
So basically
155 (being the exterior angle) is equal to 50 + x (being the opposite interior angles)
so x = 155 - 50
155 - 50 = 105
so we can conclude that x (angle T) equals 105
Answer:
105 degrees
Step-by-step explanation:
The angle measure of the exterior angle is equal to the sum of the two nonadjacent interior angles (angle V and angle T).
155 - 50 = 105
Am I really this dum* to not know how to answer this?
Other than that PLEASE HELP!!! AND ITS 10 POINTS
Answer:
3880 degrees
Step-by-step explanation:
18 gon = 18 sides
The sum of the measures of the interior angle of any polygon is the number of sides minus 2 multiplied by 180.
⇒ 18 - 2 x 180
⇒ 16 x 180
⇒ 2880

Answer:
48 stuff animals 24 myster boxes
Step-by-step explanation:
this is because the stuff animals have a greater than half the amount of getting. So you would then to 74/3. this is because if we split the total into thirds, we know that the stuff animals will have more than half. which will equal to 2/3. so will divide 74/3 we will 24, but since the stuff animals is 2/3 more likely, add or multiple 24 by 2 or add 24 again. giving us 48. then the remaining amount left of 74 will be left for the mystery boxers.
giving use the ration of 48:24
