Find the measure of < 1.

9514 1404 393

Answer:

  193.5 square units

Step-by-step explanation:

The area formula for this situation is ...

  A = 1/2Pa

where P is the perimeter of the regular polygon, and 'a' is its apothem. For a pentagon, the perimeter is 5 times the side length, so the area is ...

  A = (1/2)(5×10.6)(7.3) = 193.45

To the nearest tenth, the area is 193.5 square units.

Answer:

I believe the answer is B tell me if I'm correct please

[tex]x = \frac{7 \sqrt{3} }{2} \\ [/tex]

.

[tex] \frac{7}{x} = \frac{2}{ \sqrt{3} } \\ [/tex]

[tex]7 \times \sqrt{3} = 2 \times x[/tex]

[tex]7 \sqrt{3} = 2x[/tex]

Answer:

616 cm^2

Step-by-step explanation:

Steps to derive the answer

1. we are going to first determine the radius from the circumference

2. we would calculate the area

Circumference of a circle = 2nr

n = 22/7

r = radius

88 = 2 x 22/7 x r

Divide both sides of the equation by 2 x 7/22

r = 14

Area of a circle = nr^2

3.14 x 14^2 = 616 cm^2

Answer:

The minimum sizes of the homes the contractor should build is of 1692.24 square feet.

The maximum sizes of the homes the contractor should build is of 1927.76 square feet.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average size of homes built is 1810 ft2 with a standard deviation of 92 ft2

This means that [tex]\mu = 1810, \sigma = 92[/tex]

Middle 80%:

Between the (100-80)/2 = 10th percentile and the (100+80)/2 = 90th percentule.

Minimum size:

The 10th percentule, which is X when Z has a pvalue of 0.1, so X when Z = -1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.28 = \frac{X - 1810}{92}[/tex]

[tex]X - 1810 = -1.28*92[/tex]

[tex]X = 1692.24[/tex]

The minimum sizes of the homes the contractor should build is of 1692.24 square feet.

Maximum size:

The 90th percentule, which is X when Z has a pvalue of 0.9, so X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 1810}{92}[/tex]

[tex]X - 1810 = 1.28*92[/tex]

[tex]X = 1927.76[/tex]

The maximum sizes of the homes the contractor should build is of 1927.76 square feet.

Answer:

1) Rizza's average speed is 27 km/h.

2) The distance between Barretto and Pampanga is 294 km.

3) Aaron's journey was 3.5 hours long.

Step-by-step explanation:

1) Time taken to cove the distance = 20 minutes

60 minutes = 1 hour

So that, 20 minutes = [tex]\frac{20}{60}[/tex] hours

                                 = [tex]\frac{1}{3}[/tex] hours

Distance covered = 9 km

But,

speed = [tex]\frac{distance covered}{time taken}[/tex]

Rizza's average speed = 9 ÷ [tex]\frac{1}{3}[/tex]

                                       = 9 x 3

                                       = 27 km/h

Rizza's average speed is 27 km/h.

2) Time taken = 3.5 h

the car's average speed = 84 km/h

Distance between Barretto and Pampanga = average speed x time taken

                                           = 84 km/h x 3.5 h

                                           = 294 km

The distance between Baretto and Pampanga is 294 km.

3) The uniform speed implies that Aaron did not accelerate during his journey.

Distance covered = 210 km

uniform speed = 60 km/h

time taken = [tex]\frac{distance covered}{speed}[/tex]

                   = [tex]\frac{210}{60}[/tex]

                   = 3.5 hours

Aaron's journey was 3.5 hours long.

Answer: :Given : points G and I have coordinates (6,4) and (3,2)

To Find : Use  Pythagorean theorem  to calculate the straight line distance between points G and I

Solution:

points G and I have coordinates (6,4) and (3,2)

Draw a line parallel to y axis passing through G

Draw a line parallel to x axis passing through I

Intersection point K ( 6 , 2)

IK = 6 - 3 = 3

GK = 4 -2  = 2

ΔIKG right angled triangle

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.  

GI² = IK² + GK²

=>  GI²  = 3² + 2²

=>  GI²  = 13

=> GI = √13

using distance formula

G (6,4) and I (3,2)

= √(6 - 3)² + (4 - 2)²

= √3² + 2²

= √9 + 4

= √13

Answer:

$11988

Step-by-step explanation:

Given that,

The unit cost is given by :

[tex]C(x)=0.7x^2-462x+88218[/tex]

We need to find the minimum unit cost.

For minimum cost,

Put [tex]\dfrac{dC}{dx}=0[/tex]

So,

[tex]\dfrac{d}{dx}(0.7x^2-462x+88218)=0\\\\1.4x-462=0\\\\x=\dfrac{462}{1.4}\\\\x=330[/tex]

Put x = 330 in equation (1).

[tex]C(330)=0.7(330)^2-462(330)+88218\\\\=\$11988[/tex]

So, the minimum unit cost is equal to $11988.

The time at which Michelle finish her dance class is given by the equation A = 8 : 10 PM

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the time at which Michelle finished her class be A

Now , the time required for the dance class = 85 minutes

So , the time required for the dance class = 1 hour 25 minutes

The time at which Michelle started her class = 6 : 45 PM

So , the time at which Michelle finished her class A = time at which Michelle started her class + time required for the dance class

Substituting the values in the equation , we get

The time at which Michelle finished her class A = 6 : 45 PM + 1 hour 25 minutes

On simplifying the equation , we get

The time at which Michelle finished her class A = 8 : 10 PM

Hence , the equation is A = 8 : 10 PM

Answer:

$360

Step-by-step explanation:

If Shelly wants 6 rose bushes, and each bush costs $40, then you can multiply 6 by 40 to find the total amount of money Shelly will spend on them if she plants them herself. 6 x 40 = 240. You can then subtract 240 from 600 to find the amount of money she saves. 600 - 240 = 360

Answer:

$360

Step-by-step explanation:

im pretty sure its $360 because each bush is 40, 40x6=240. The contracter wants 600 when the bushes only cost $240 altogether. take 600 and subtract 240. you get 360:). hope that helps!!

Answer:

We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.

Step-by-step explanation:

The confidence interval for population mean is given by:-

[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex], where n= sample size, [tex]\overline{x}[/tex] = sample mean, z* = critical value for confidence level, [tex]\sigma[/tex]= standard deviation.

z*  for 90% confidence level = 1.645

As per given, the required confidence interval is

[tex]1.87\pm (1.645)\dfrac{1.64}{\sqrt{1494}}\\\\\approx1.87\pm0.070\\\\=(1.87-0.07,\ 1.87+0.07)\\\\=(1.8, 1.94)[/tex]

Hence, We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.

Answer:

The answer is "789.03 and 806.16".

Step-by-step explanation:

[tex]y\^ \ \ = -0.45 + 3.78(x) -11.88(d_1) + 5.25(d_2)[/tex]

For point a:

Calculating the value for [tex]y\^ \ \ x = 212,\ \ d_1 = 1, and \ \ d_2 = 0[/tex]

[tex]y\^ = -0.45 + 3.78(212) -11.88(1) + 5.25(0)[/tex]

     [tex]= -0.45 + 801.36 -11.88 + 0\\\\= 789.03[/tex]  

For point b:

Calculating the value of [tex]y\^ \ \ for \ \ x = 212, \ \ d_1 = 0, and \ \ d_2 = 1[/tex]

[tex]y\^ = -0.45 + 3.78(212) -11.88(0) + 5.25(1)[/tex]
