Answer:

1. m∠CUK = 70°

2. m∠K = 112°

Step-by-step explanation:

1. The given parameters of the parallelogram LUCK are;

∠C = 68°

∠LUK = 42°

From the diagram of parallelogram LUCK obtained from an online source, we have;

Given that LUCK = A parallelogram, we have;

The same side interior angles ∠C and ∠U are supplementary angles

Therefore;

∠C + ∠U = 180°

∠U = 180° - ∠ C

∴ ∠U = 180° - 68° = 112°

∠U = 112°

By angle addition property, ∠U = ∠LUK + ∠CUK

∴ m∠CUK = ∠U - ∠LUK

By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;

m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°

m∠CUK = 70°

2. By angle addition property, we have;

∠K = ∠LKU + ∠CKU

∠LKU and ∠CUK are alternate interior angles

∴ ∠LKU = ∠CUK = 70°

Similarly, ∠CKU and ∠LUK are alternate interior angles

∠CKU = ∠LUK = 42°

m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°

m∠K = 112°.

Step-by-step explanation:

If you add all of the digets up you get: 86

86 divided by the quanity of numbers is: 17.6

Answer:

x = 6

Step-by-step explanation:

Tip: You want to isolate the x-variable on one side of the equation to find its value.

1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.

2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.

3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.

4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.

I hope that helps! :)

Answer:

  x = 8

Step-by-step explanation:

Assuming the figure is a parallelogram, the diagonals bisect each other. That means ...

  3x -11 = x +5

  2x = 16 . . . . . . . add 11-x to both sides

  x = 8 . . . . . . divide by 2

Answer:

the answer is x=8

Answer:

the number of centimeters is 1,750

Step-by-step explanation:

The computation of the number of centimeters is shown below;

Given that

1 dekameter = 1000 centimeter

And, there are 1.75 dekameters

So, the number of centimeter is

= 1000 × 1.75

= 1,750 centimeter long

Hence, the number of centimeters is 1,750

Therefore the same would be considered and relevant too

Answer:

9

Step-by-step explanation:

V=pi (r squared) (h/3)

75pi = 25pi (h/3)

Divide both sides by 25 pi

3= h/3

Multiply both sides by 3

h=9

Answer:

99.7% of the boys are between 54 and 84 inches tall.

Step-by-step explanation:

The heights 54 and 84 inches are 3 standard deviations away from the mean. Thus, 99.7% of the boys are between 54 and 84 inches tall.

The percentage of the boys are between 54 and 84 inches tall is 99.7%

What is percentage?

Percentage a relative value indicating hundredth parts of any quantity.

What is empirical rule?

The empirical rule or  the three-sigma rule , is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations of the mean.

The empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

From question mean(μ) = 69 in. and  standard deviation(σ)= 5 in.

(µ ± σ) = (69 ± 5)

           =64 - 74

           =68%

(µ ± 2σ) =(69 ± 10)

            =59 -79

            =95%

(µ ± 3σ) =(69 ± 15)

             =54 -84

             = 99.7%

Thus the percentage of the boys are between 54 and 84 inches tall is 99.7%

Answer:

Radius:2

Diameter:4

Area:12.56

Circumference: 12.56

Answer:

3/50

Step-by-step explanation:

Slope m = y2-y1/x2-x1

From the coordinate

x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5

Substitute;

m = (3/5 - 2/3)/-4/9-2/3

m = (9-10/15)/(-4-6/9)

m = -1/15/-10/9

m = -1/15 * -9/10

m = 9/150

m = 3/50

Hence the slope of the line passing through the points is 3/50

Answer: $0.10 per fluid ounce

Step-by-step explanation:

Kayla bought two-pints for $3.20.

First convert this quantity to fluid ounces.

1 pint = 16 fluid ounces

If 2 pints were bought therefore, this would be:

= 2 * 16

= 32 fluid ounces

32 fluid ounces cost $3.20.

Cost per fluid ounce is therefore:

= 3.20 / 32

= $0.10 per fluid ounce

Answer:

$0.10 per fluid ounce

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Step-by-step explanation:

Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.  

Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual

Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.
