A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.43 inches. So, the diameter of the tire on an actual car must be inches. Your answer must be correct to one decimal place.

Answers

Answer 1

Answer:27.52 inches

Step-by-step explanation:

Given

Scale factor [tex]\frac{1}{64}[/tex] i.e.

[tex]\dfrac{\text{Model}}{\text{Prototype}}[/tex]

The diameter of the model tire is 0.43 inches

Scale factor = [tex]\dfrac{\text{dia. of model}}{\text{dia. of actual car}}[/tex]

[tex]\frac{1}{64}=\frac{0.43}{D}\\D=64\times 0.43=27.52\ \text{inches}[/tex]

karen purchased a DVD player on sale. The original selling price was ​$159.92 The sale price was ​$179. 30 find the percent markdown

Answers

Answer:

Step-by-step explanation:

Answer:

19.26%

Step-by-step explanation:

Given the original selling price of DVD player as ​$179.30 and the new sale price to be ​$144.77, the the first step in finding the percent​ markdown is to take the difference between the original selling price and the sale price to give $179.30 - $144.77 = $34.53

Percent markdown = original selling price- new sale price/original selling price × 100%

Percent markdown = $34.53/$179.30 × 100%

% markdown = 19.26%

Step-by-step explanation:

During its first year, there were 138 volunteers at a community outreach program. Over the next 2 years, there were 156 volunteers and 175 volunteers, respectively. What is the percent of increase in volunteers from Year 1 to Year 2 and from Year 1 to Year 3? Round to the nearest tenth percent if necessary.

Answers

Answer:

0.1%

Step-by-step explanation:

138 into a percent=1.38%

156 into a percent=1.56%

175 into a percent=1.75%

1.38-1.56=0.18

1.56-1.75=0.19

0.19-0.18= 0.1%

The increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

Percentage

The percentage can be defined as a relative value that represents the hundredth part of any quantity.

Given that the number of volunteers in a program during year 1, year 2 and year 3 are 138, 156 and 175 respectively.

The percentage of increase in volunteers from year 1 to year 2 is given below.

Volunteers (%) = [tex]\dfrac {156-138}{138} \times 100[/tex]

Volunteers (%) = 13.04%

The percentage of increase in volunteers from year 1 to year 3 is given below.

Volunteers (%) = [tex]\dfrac {175-138}{138} \times 100[/tex]

Volunteers (%) = 26.81 %

Hence we can conclude the increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options.

Answers

Answer:

16 < n < 40

Step-by-step explanation:

use triangle inequality theorem:

n = length of third side

12 + 28 > n;    n > 40

12 + n > 28;    n > 16

n + 28 > 12  (this inequality can be discounted because it results in a negative)

The grizzly bear population in Yellowstone National Park in 1970 was about 270. Over the next 35 years, it increased by about 115%. What was the population in 2005?

Answers

Answer: 311 bears

Step-by-step explanation:

Population increased by 115% in the 35 years from 1970 to 2005.

Population in 2005 is:

= 270 * 115/100

= 310.5

= 311 bears

Answer:

581

Step-by-step explanation:

270x%115=310.5

We have to round 310.5 to the nearest So 310.5 will be 311  

So if it increased by 115%  we have to add the 115% to 270

270+311= 581  

By the 2005 the population will be 581

Answers

Step-by-step explanation:

Angle ACO = 140° - x. (Sum of angles in a triangle is 180°)

Now draw the line OD. The triangles ODC and OBC are congruent via the SSS congruence property. (OD and OB are both the radius of semicircle, common side OC, and side CD = CB is given)

Hence Angle BCO = Angle ACO = 140° - x.

Since triangle OBC is an isosceles triangle with OC = OB, this means that Angle CBO is also 140° - x.

By Exterior Angle theorem,

we have Angle AOC = Angles BCO + CBO

=> x = (140° - x) + (140° - x)

=> 3x = 280°

=> x = 280°/3. (B)

Answer:

x=9 y=45

Step-by-step explanation:

y=4x + 9.......(1)

y= 5x.........(2)

Substitute 5x for y in equation 1.

5x= 4x + 9

5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)

x = 9

  15, 16.  not possible

Step-by-step explanation:

9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.

__

13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.  

When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.

13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF

__

15, 16. With only one angle and one side, it is not possible to prove congruence.

_____

Additional comment

With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.

(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)
