10. What is the measure of angle y?
Answer:
50°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
The square (bottom left of triangle) is a right angle and right angles always equal 90° and the other one is 40°, so you would add them up. This equals 130°.
To find y, you would have to do 180° minus 130° which is 50°.

question is-- Northern Tier Gardens has hired you for a summer job installing water gardens. they have circular water garden pools available in a variety of sizes. the manager has asked you to create a table to show the circumference and area of the company's various water garden pools. use 3.14 for π and round each answer to the nearest hundredth. === 20 PTS.
Answer:
See explanation
Step-by-step explanation:
Atlantic area = πr² = (3.14)(2.5)² = 19.63 ft²
Circumference = 2πr = 2(3.14)(2.5) = 15.7 ft
Pacifica A = (3.14)(6)² = 113.04 ft²
C = 2(3.14)(6) = 37.68 ft
Mediterranean A = (3.14)(1.75)² = 9.62 ft²
C = 2(3.14)(1.75) = 10.99 ft
Baltica A = (3.14)(1)² = 3.14 ft²
C = 2(3.14)(1) = 6.28 ft
Japanesque A = (3.14)(2.25)² = 15.90 ft²
C = 2(3.14)(2.25) = 14.13 ft
Floridian A = (3.14)(3.25)² = 33.17 ft²
C = 2(3.14)(3.25) = 20.41 ft

Use the rule "subtract 6" to create a sequence of 10 numbers starting with 100. (explanation/work needed)
Answer:
100 -6 = 94
94 - 6 = 88
88 - 6 = 82
82 - 6 = 76
76 - 6 = 70 We can then show and prove 70 -> 64.
64 -> 58
58 -> 52
52 -> 46
46 -> 40
As numbers that end in 0, decrease to units that end in 4,8,2,6,and back to zero.
= all numbers that end with 0 have numbers that end in 4,8,2,6,0 when subtracting 6.
As 6 x 10 = 60 and 60 +40 = 100
We cna prove 4+8+2+6 = 20
20+20 = 40 and would continue this pattern to get to 10 we can then see the sequence of how 30/6 and proves each 5 number coordinate being 4,8,2,6,0 until we get to 10.
We then find 4,-2,-8,-14,and-20 it skips out 2 and 6 here on the neutral line but then starts and changes the sequence end numbers to -26 -32, -38,-44 and -50. This proves that-2 and -8 has significance and shows us a real sum that on negative -2 -8 = 6
The inverse of the 40 marker in the positive shows us 60
and 60 -50 = 10 being our 2nd positive closest to zero.
These were repeated twice and show 40 deducted and a further 18 as 0 counts for 2 subtractions 100-6 70-6 just like 94 +6 = 100 and like 70+6 = 76 and 40+6 = 46
3 x 6 = 18
40+ 18 = 58
100-58 = 42 and shows us a reflection again with 4 and 2
not just 4+2 = 6 it shows is 4/2 = 2 42/2 = 21 and 7 being a divider represents the first sequence group of 10 from 100 being 70 and just as significant in a decrease of 6 in relation to 100.
100-70 = 30
30-6 = 24
24 / 6 = 4
and we mark 4 as our first unit with relation to 100 and its decrease of 6 in sequence.
This may help you remember that 30 x 100 = 3000 and would be increasing by 6 x 180 times. But when we decrease from here we find 2400 a likely number as 3000-600 - 2400
This may help you remember that 400/6 = 66.6666666667 and why decrease always ends up as negative when 400 x 6 = 2400 and is a much more dividable number. and that 400 is not dividable by 6 in the first place, and may be linked to why a neutral zero number may show 4 and 10 and -2 and -8 where all these numbers divide into 400 6 just doesn't work in any even hundred number below 1200 except for 600 as we know and recall 6 divides into 30 and 18 but not into 40, just counts back to inverse 40 from 100 as its counting 2 x 30 = 60. It does divide into 2400 and that is a midway point back down to 1800 from 3000. So this may help you remember divisors of larger numbers.
A sample proportion of 0.44 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, each with a sample size of 100 and a point estimate of 0.44. The minimum sample proportion from the simulation is 0.32, and the maximum sample proportion from the simulation is 0.50. What is the margin of error of the population proportion using an estimate of the standard deviation?
Answer:
±0.06
Step-by-step explanation:
To find the margin of error using the standard deviation method, use the equation [tex]2(\frac{maximum-minimum}{6})[/tex].
In this situation, it would look like this: [tex]2(\frac{0.50-0.32}{6})[/tex]. Using this equation, you can find the margin of error by using the standard deviation method.
[tex]2(\frac{0.50-0.32}{6})[/tex]
[tex]2(\frac{0.18}{6})[/tex]
[tex]2(0.03)[/tex]
[tex]0.06[/tex]
Hope this helps!
(I know this is right because its what I answered on the test, and got 100%)
The margin of error of the population proportion using an estimate of the standard deviation is 0.06
we have given that,
A sample proportion of 0.44 is found.
The minimum sample proportion from the simulation is 0.32
The maximum sample proportion from the simulation is 0.50
What is the formula for the margin of error using the standard deviation method?The formula for the margin of error using standard deviation is,
[tex]2(\frac{max-min}{6} )[/tex]
Use the given value in the formula we get,
[tex]2(\frac{0.50-0.32}{6} )[/tex]
Using this equation, you can find the margin of error by using the standard deviation method.
[tex]2(\frac{0.50-0.32}{6} )\\\\=2(\frac{0.18}{6})\\\\ =2(0.03)\\\\=0.06[/tex]
Therefore we get,
The margin of error of the population proportion using an estimate of the standard deviation is 0.06

A. z = x + y − 2; x represents Micah's age, y represents Becky's age, and z represents Jacob's age B. x = y + z + 2; x represents Jacob's age, y represents Micah's age, and z represents Becky's age C. x = 2 + y + z; x represents Becky's age, y represents Jacob's age, and z represents Micah's age D. y = x + z − 2; x represents Jacob's age, y represents Becky's age, and z represents Micah's age
The equation that represents Jacob's age is x = y + z + 2
From the question, the following information was provided :
Jacob's age is two years more than the sum of the ages of his siblings Becky and Micah.
This above information can be represented with the equation below
Jacob = 2 + ( Becky + Micah) (equation 1)
If :
x represents Jacob's age
y represents Micah's age
z represents Becky's age
Equation 1, can be rewritten as x = y + z + 2
Micah's age can be determined by making Micah the subject of the formula in the above equation
Micah = Jacob - Becky - 2 (equation 2)
If :
x represents Micah's age
y represents Becky's age
z represents Jacob's age
Micah's age can be rewritten as :
x = z - y - 2
Becky's age age can be determined by making Becky the subject of the formula in the first equation.
Becky = Jacob - Micah - 2 (equation 3)

Answer:
(a) ∠EFH = 68°
(b) ∠EGF = 21°
Step-by-step explanation:
(a) The given parameters are;
The diameter of the circle = Segment [tex]\overline{EG}[/tex]
Arc [tex]m\widehat{FG}[/tex] = 138°
∠GFH = 22°
∠ EFG = (Angle subtended by the diameter EG at the center)
Arc mEG = 180° (Arc subtended by the diameter of a circle = 180°)
∠ EFG is subtended by the diameter EG at the center
∴ ∠ EFG = 90° (Angle at the center = 2 times angle at the circumference)
∠EFG = ∠EFH + ∠GFH (Angle addition postulate)
∴ ∠EFH = ∠EFG - ∠GFH = 90° - 22° = 68°
∠EFH = 68°
(b) ∠EGF
Arc GH = 44°
Arc mFE + Arc [tex]m\widehat{FG}[/tex] + Arc mEHG = 360 (Sum of angles at the center of a circle)
Arc mFE = 360 - ( Arc [tex]m\widehat{FG}[/tex] + Arc mEHG )
Arc mFE = 360 - 180 - 138 = 42°
∠EGF = Arc mFE/2 (Angle at the center = 2 times angle at the circumference)
∠EGF = 42/2 = 21°
∠EGF = 21°
Two trains leave New York at the same time heading in opposite directions. Train A travels at 4 5 the speed of train one. After seven hours they are 693 miles apart. What was the speed of train A?
Answer:
Speed of train A is 44 miles/hr.
Step-by-step explanation:
Let the speed of train A = [tex]u\ miles/hr[/tex]
Let the speed of train one = [tex]v\ miles/hr[/tex]
Train A travels at [tex]\frac{4}{5}^{th}[/tex] the speed of train one.
i.e.
[tex]u = \dfrac{4}{5}v \\\Rightarrow v =\dfrac{5}{4}u.... (1)[/tex]
Distance traveled = 693 miles
Time taken = 7 hours
They are travelling in opposite directions so the resultant speed will appear to be faster.
Relative speed = [tex]u+v\ miles/hr[/tex]
The trains are 693 miles apart in 7 hours that means they have traveled a total distance of 693 miles in 7 hours with a speed of ([tex]u+v[/tex]) miles/hr.
Using the formula:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
[tex]u+v = \dfrac{693}{7}\\\Rightarrow u+v=99 ...... (2)[/tex]
Putting the value of v using equation (1):
[tex]\dfrac{5}4u+u=99\\\Rightarrow 5u+4u = 99 \times 4\\\Rightarrow 9 u = 99 \times 4\\\Rightarrow u = 11 \times 4 = \bold{44\ miles/hr}[/tex]
Speed of train A is 44 miles/hr.

Equation 2: 12x + 5 < -4
Equation 1: 5x - 4 > 12
