Answer:

Step-by-step explanation:

In 1908, a Model T cost $950. This means that the initial price was $950. The car's price dropped to $280 in the year 1927 due to it's increased efficiency.

The decrease in price is determined by subtracting the current price in 1927 from the initial price in 1908. It becomes

950 - 280 = $670

To determine the percentage decrease in price from 1908 to 1927, we will divide the decrease in price from 1908 to 1927 by the initial price in 1908 and multiply by 100. It becomes

670/950 × 100

= 70.53%

There are 5 different coloured cups in a row.
Marizza181 [45]

There are 12 possible arrangements.

------------------------

  • Considering that the blue cup has to be on one end, we consider the number of arrangements possible with the other 4 cups, then multiply by 2(considering the blue on each end).

------------------------

  • Considering green and yellow before red and purple, there are 2 \times 2 = 4 outcomes(G-Y-R-P, G-Y-P-R, Y-G-R-P and Y-G-P-R).
  • Another two possible outcomes are yellow-purple and green-red, or vice-versa, thus 4 + 2 = 6 outcomes.
  • To account for the blue on the end, multiplying by 2. 2 \times 6 = 12
  • There are 12 possible arrangements.

According to astronomers, what is a "light year" answer key
liberstina [14]
A light-year is defined as the distance the light can cover in one year.

The light travels at speed of c=3 \cdot 10^8 m/s, and one year converted into seconds is
1 y = 365  \frac{d}{y} \cdot 24  \frac{h}{d} \cdot  60 \frac{m}{h} \cdot 60  \frac{s}{m}=3.15 \cdot 10^7 s

So the distance covered by the light in one year is
S=vt =(3 \cdot 10^8 m/s)(3.15 \cdot 10^7 s)=9.45 \cdot 10^{15} m
And this is the distance that corresponds to one light-year.

1. 112<br><br> 2. 136 <br><br> 3. 68 <br><br> 4. 158 <br><br> 5. 129
RideAnS [48]

Answer:

4. 158

Step-by-step explanation:

First let's make things a little simpler and put these arcs in terms of x.  We know that the degree measure around the outside of a circle, regardless of its size, is 360.  So let's say that arc BC is x.  That means that arc BDC is 360 - x.  This is because arc BC + arc BDC = 360.  Substituting in our x's we have:

x + 360 - x = 360 and

360 = 360.  (That's just the proof that putting in our x's as we did does in fact work!)

Following the formula then, we have

22=\frac{1}{2}(360-x-x) and

22=\frac{1}{2}(360-2x)

Multiply both sides by 2 to get rid of the fraction and get

44 = 360 - 2x

Subtract 360 rom both sides to get

-316 = -2x

Divide both sides by -2 to get that x = 158

Since we are looking for arc BC and we designated arc BC as our x, that means that arc BC = 158.
