Sort the numbers from LEAST TO GREATEST . > 6.82 , 6.803 , 6.650 , 6.68
Answer:
6.650, 6.68, 6.803, 6.82
Step-by-step explanation:
You just treat the decimals as you would whole numbers. Try imagineing them as whole numbers and its a lot easier like this. 6.82 and 6.68 as 682 and 668, you can clearly see 668 is lower than 682 so it comes first. Therefore, 6.68 is lower than 6.82 and comes first.

There is a
% chance of finding a defective headset.
Answer:
2.5
Step-by-step explanation:
273/280 = 97.5%
2.5% are defective
If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects, There is a 2.5% chance of finding a defective headset.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A manufacturer tests a certain number of the headsets that are produced each day.
If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,
The chance of finding a non-defective headset
= 273/280
= 97.5%
The chance of finding a defective headset
= 100% - 97.5%
= 2.5% are defective

Glenn has a garden that is shaped like a rectangle.
The perimeter of his garden is 7012 feet.
The length of the garden is 2434 feet.
What is the width of the garden?
21 ft o 11ft o 10 ½ ft o 45 ¾ ft
Answer:
Solution given:
The length of the garden[l] = 2434 feet.
breadth or width [b]=b
perimeter of his garden = 7012 feet.
2[l+b]=7012ft
2434+b=7012/2
b=3506-2434
b=1072
So the width of the garden is 1072ft.
During a storm one and five hundredths inches of rain fell near Marie's house which shows the amount of rain in standard form?
Answer:
1.05 * 10⁰
Step-by-step explanation:
Standard form is a way of representing either very large or very small numbers easily.
If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).
Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.
Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05
Amount of rain in standard form = 1.05 * 10⁰
Please help this is late work for geometry and I keep getting this awnser wrong
Answer:
w = 12°
Step-by-step explanation:
Angle J = Angle H
Angle K = Angle I
So lets find the sum of the entirety of angles
360° = 2w + 34° + 2w + 34° + 4w + 74° + 4w + 74°
360° = 12w + 68° + 148°
360° = 12w + 216°
Subtract 216° from both sides
360° - 216° = 12w + 216° - 216°
144° = 12w
Divide both sides by 12
144°/12 = 12w/12
12 = w
w = 12°

-Chetan K
Answer:
58°Step-by-step explanation:
Consider that adjacent angles are supplementary in any parallelogram (including rhombus).
m∠J + m∠K = 180°(2w + 34) + (4w + 74) = 180Solve for w:
6w + 108 = 1806w = 72w = 12Find the value of ∠J:
m∠J = 2w + 34 = 2(12) + 34 = 58It costs $23,000 to attend 1 year at Texas State University, and I already saved up $4,000. How much money would I have to save each month for the next year to have the full $23,000?

Find the slope of the line through the given points.
(-1,1) and (3, -7)
Answer:
Slop of the line M = -2
Step-by-step explanation:
Given coordinates;
(-1 , 1) , (3 , -7)
Find:
Slop of the line
Computation:
We know that;
x1 = -1
x2 = 3
y1 = 1
y2 = -7
Slop of the line M = Δy / Δx
Slop of the line M = (y2 - y1) / (x2 - x1)
Slop of the line M = (-7 - 1) / [3 - (-1)]
Slop of the line M = (-8) / [3 + 1]
Slop of the line M = (-8) / (4)
Slop of the line M = -2

Which is the best description for the lines m and k?
A)
parallel
B)
perpendicular
intersecting and parallel
D
intersecting but not perpendicular
===================================================
Explanation:
I've highlighted lines m and k in red (see diagram below). We'll ignore the other lines. On those red lines, I've added blue points with their coordinate locations.
Line m has point A = (-3, 5) and B = (-1, -3). Let's use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-3-5)/(-1-(-3))
m = (-3-5)/(-1+3)
m = -8/2
m = -4
The slope of line AB, aka line m, is -4.
-------------
Line k has points C = (1, 5) and D = (3, -3) on it. We'll use the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (-3-5)/(3-1)
m = -8/2
m = -4
The slope of line CD, aka line k, is -4
---------------
Both lines m and k have the same slope of -4. Therefore, the two lines are parallel. Parallel lines always have the same slope, but different y intercepts. So these lines will never intersect one another.

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have
2 x 4k - 2 x 3
which gives you
8k - 6
Answer:
Taniyah
Step-by-step explanation:
Taniyah is correct because you need to:
diistribute : 8k - 6 - 6k = 14
combine like terms : 2k - 6 = 14
add 6 to both sides : 2k - 6 + 6 = 14 + 6
simplify : 2k = 20
divide both sides by the same factor : 2k/2 = 20/2
simplify : k = 10
Increase 18 by a half
Answer:
36
Step-by-step explanation:

just multiply by 2 or divide by 2
Answer:
27
Step-by-step explanation:
increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27

what is a square root?
Answer:
A number multiplied by its self for ex 7 x 7 = 49 square root of 49 is 7
Answer:
A square root of a number is a value that, when multiplied by itself, gives the number. 6 · 6 = 36, so a square root of 36 is 6. You are probably curious why I said a square root and not the square root. - 6 · - 6 = 36. - 6 is a square root of 36. The symbol is √ which always means the positive square root.
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
√36 = 6
√49 = 7
√64 = 8
√81 = 9
√100 = 10
