Figure I And Figure II Are Similar Figures.Which Proportion Must Be True?*answers Are In The Picture*

Answers

Answer 1

Answer:

St/EF = WR/CD

Step-by-step explanation:

Answer 2

The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Thus the option H is the correct option.

To find the correct proportion we need to know about the properties of slimier polygon.

What are the properties of similar polygon?

Two polygons are said to be similar or congruent pentagon-

The corresponding angle of two pentagons are congruent.

The ratio of corresponding sides is same for all the sides.

The figure given in the problem of similar two polygons with six sides.

Rearrange the second figure as shown in figure.

As for the similar polygons, the ratio of corresponding sides is same for all the sides.

Thus the sides shown in the two rearranged figure must be same. Therefore,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Hence the correct proportion is,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Thus the option H is the correct option.

Answer:

[tex]\angle BDA = 72^{\circ}[/tex]

[tex]\angle DAB = 36^{\circ}[/tex]

[tex]\angle BDC = 108^{\circ}[/tex]

[tex]\angle BCD = 36^{\circ}[/tex]

[tex]\angle DBC = 36^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle ABD = 72^{\circ}[/tex]  

Required

Determine the missing angles

Since AB = AD, then:

[tex]\angle ABD = \angle BDA[/tex] --- Base angles of an isosceles triangle

Hence:

[tex]\angle ABD = \angle BDA = 72^{\circ}[/tex]

[tex]\angle ABD + \angle BDA + \angle DAB = 180^{\circ}[/tex] --- angles in a triangle

[tex]72^{\circ} + 72^{\circ} + \angle DAB = 180^{\circ}[/tex]

[tex]144^{\circ} + \angle DAB = 180^{\circ}[/tex]

Collect Like Terms

[tex]\angle DAB = 180^{\circ} - 144^{\circ}[/tex]

[tex]\angle DAB = 36^{\circ}[/tex]

[tex]\angle BDA + \angle BDC = 180^{\circ}[/tex] --- angle on a straight line

[tex]72^{\circ} + \angle BDC = 180^{\circ}[/tex]

[tex]\angle BDC = 180^{\circ} - 72^{\circ}[/tex]

[tex]\angle BDC = 108^{\circ}[/tex]

Since ABC is isosceles, then:

[tex]\angle DAB = \angle BCD = 36^{\circ}[/tex] --- base angle of isosceles

[tex]\angle BCD = 36^{\circ}[/tex]

Lastly:

[tex]\angle BCD + \angle BDC + \angle DBC = 180^{\circ}[/tex]

[tex]36^{\circ} + 108^{\circ} + \angle DBC = 180^{\circ}[/tex]

[tex]\angle DBC = 180^{\circ} - 36^{\circ} - 108^{\circ}[/tex]

[tex]\angle DBC = 36^{\circ}[/tex]

A scale of the Golden Gate Bridge in San Francisco Bay has

a main span that is 20 inches long. If the main span of the

bridge is 4200 feet long, what is the scale of the model?


Answer: 2520ft

Answers

Answer:

2520ft

Step-by-step explanation:

Calculation for what is the scale of the model?

Let x will be the span length

Hence,

x= 4200 feet long/20 inches long

x=210

Thus:

1 inch = 210 ft

1 ft = 2520

=2520ft

Therefore the scale of the model will be 2520ft

What is the value of x in the solution to the this system of equations:
y=-1/2x + 2
y - 2x = -3

Answers

Answer:

x=2 and y=1

Step-by-step explanation:

hope this helps!

Answer:

x = 2

Step-by-step explanation:

For system of equations, you need to equal them to each other. First, you need to isolate y on one side of the equation in [tex]y - 2x = -3[/tex]

[tex]y = -3 + 2x[/tex]

Now, equal the equations to each other:

[tex]-\frac{1}{2}x + 2 = -3 + 2x[/tex]

Add [tex]\frac{1}{2} x[/tex] to both sides of the equation:

[tex]2 = -3 + (2x + \frac{1}{2}x) = -3 + (\frac{4}{2}x + \frac{1}{2}x) = -3 + \frac{5}{2} x[/tex]

Subtract add 3 to both sides of the equation:

[tex]5 = \frac{5}{2}x[/tex]

Divide [tex]\frac{5}{2}[/tex] on both sides of the equation. Remember: when you divide a fraction, you multiply by the reciprocal. See below:

[tex]\frac{2}{5} * 5 = x[/tex]

[tex]\frac{10}{5} = x[/tex]

[tex]x = 2[/tex]

Check your work:

MY TEACHER MADE ME DO THIS LOL

A manufacturer of cell phone screens has found that 5 percent of all screens produced have defects. Let pd represent the population proportion of all cell phone screens with a screen defect, therefore pd=0.05. For the sampling distribution of the sample proportion of cell phone screens from this manufacturer with a screen defect for sample size 400, μpˆd=0.05. Which of the following is the best interpretation of μpˆd=0.05 ?

For a randomly selected cell phone screen from this population, the mean number of screen defects for the selected screen will be equal to 0.05.

For a randomly selected cell phone screen from this population, the mean number of screen defects for the selected screen will be equal to 0.05.
A

For every sample of size 400 from this population, the proportion of cell phone screens with a screen defect will be 0.05.

For every sample of size 400 from this population, the proportion of cell phone screens with a screen defect will be 0.05.
B

For all samples of size 400 from this population, the mean number of screen defects for the samples is 0.05.

For all samples of size 400 from this population, the mean number of screen defects for the samples is 0.05.
C

For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
D

For all samples of size 400 from this population, the standard deviation of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

Answers

Answer:

For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

Step-by-step explanation:

College Board

Using the Central Limit Theorem, it is found that the correct option is:

C  For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

By the Central Limit Theorem, for a proportion p in a sample of size n, the mean of the sampling distribution of sample proportions is [tex]\mu = p[/tex], while the standard error is [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex

In this problem, the mean of the sampling distribution of sample proportions is 0.05, that is, the mean proportion of all samples, hence, the correct option is C.

what single decimal multiplier would you use to increase by 14% followed by a 1% decrease? ​

Answers

Answer:

1.1286

Step-by-step explanation:

Increasing something by 14% is the same as taking 114% of it, and decreasing it by 1% is the same as taking 99% of it. 114% is 1.14 as a decimal, and 99% is 0.99 as a decimal, so multiplying the two together, we get the single decimal

1.14 · 0.99 = 1.1286

12.86% or a multiplier of 1.1286.

Assume the number 100.

100(1.14)=114
114(0.99)=112.86

Consider angle θ in Quadrant ll, where cos θ= -12/13. what's the value of sin θ​

Answers

Answer:

5/13

Step-by-step explanation:

According to SOH CAH TOA

cos theta = adj/hyp = -12/13

Get the opposite using pythagoras  theorem

13^2 = (-12)^2 + opp^2

169 = 144 + opp^2

opp^2 = 169-144

opp^2 = 25

opp = 5

Get sin θ​

sin θ​ = opp/hyp

sin θ​ = 5/13

hence the value of  sin θ​ is 5/13
