8 units

Step-by-step explanation:

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.

It is impossible to specify an equilateral triangle using rational coordinates.

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

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

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

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

*7      *7

x=2.8

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]

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

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.

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

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

Answer:

The surface area of the prism is 108 square in.

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

Answer:

x = 5
