Answer:

<S = 60

Step-by-step explanation:

The arc TR and the central angle (T to the center then to R ) are equal.

So the Central angle is 120o

S anywhere on the minor arc is 1/2 the central angle.

<S = 1/2 120

<S = 60

Answer:

60°

Step-by-step explanation:

the relationship between angle RST and its arc TR is:

2m∠(RST)=m(arcTR);

using this formula m∠(RST)=0.5*m(arcTR);

m∠(RST)=60°

Breaking down Brown versus Whitman: Example 2 of the chapter 1 discusses an exit poll taken during the 2010 California gubernato
son4ous [18]

Answer:

(A) Population data

(B) The figures

(C) The classification of votes by political party

Step-by-step explanation:

(A) These results summarize population data. The population is the total 3,889 voters from whom information was collected.

The samples would be

- Voters registered as Democrats  (1,633)

- Voters registered as Republicans  (1,206)

- Independent Voters  (1,050)

The total of members in each sample equals the total number of people in the population.

(B) A descriptive aspect of the result is the figures or percentages. They describe how (in percentage) voters penned their votes for Brown and how they penned their votes for Whitman. NOTE: To get the percentage or fraction of those who voted for Whitman, simply subtract the percentage of Brown's supporters from a total of 100%.

(C) An inferential aspect of the results is the classification of votes by different parties (the samples are the different parties involved here). This helps to infer the sources of support for Brown and the sources of support for Whitman.

For example, if the total votes for Brown (in population result analysis) are low, the Republicans are the major reason why!

TIME REMAINING 24:59 Ten members of Balin's soccer team ran warm ups for practice. Each member ran the same distance. Their comb
Crazy boy [7]

Answer:

The equivalent expression = 1/12 of a mile

Step-by-step explanation:

Total distance of 10 members of the Balin's soccer club =5/6 of a mile

To find the distance that each member ran, Balin wrote the expression:

5/6 ÷ 10

Which expression is equivalent to Balin's expression?

5/6 ÷ 10

= 5/6 × 1/10

= 5/60

= 1/12 of a mile

Each member of the Balin's soccer club ran 1/12 of a mile

The equivalent expression to 5/6 of a mile divided by 10 members of the Balin's soccer club is 1/12 of a mile

The sum of two numbers is 26. Four less than four times the smaller number is equal to the larger number x. Find the larger numb
Svet_ta [14]
Hey there!

This question just wants you to create an equation and solve. In this case, the larger number is equal to x. To find the smaller number, we would need to multiply x by 4 and subtract 4 from it. This means that the smaller number is equal to (4x – 4). You add the two numbers, x and (4x – 4), to get 26. Your final equation is:

x + (4x – 4) = 26

Now, just solve. 

x + 4x – 4 = 26
(5x – 4) + 4 = (26) + 4
(5x) ÷ 5 = (30) ÷ 5
x = 6

Finally, just plug in 6 for both numbers to get your answer. 

(6) + (4(6) – 4) = 26
6 + 20 = 26

Your two numbers are 6 and 20. 

Hope this helped you out! :-)

Factorise fully 18e^2f^3-12e^2f
Alexeev081 [22]

Answer:

18e^2f^3-12e^2f = 6e^2f(3f^2-2)

Step-by-step explanation:

Given

18e^2f^3-12e^2f

Required

Factorize:

18e^2f^3-12e^2f

Express 18 as 6 * 3 and 12 as 6 * 2

18e^2f^3-12e^2f = 6*3e^2f^3-6*2e^2f

Factor out 6

18e^2f^3-12e^2f = 6(3e^2f^3-2e^2f)

Factor out e^2

18e^2f^3-12e^2f = 6e^2(3f^3-2f)

Factor out f

18e^2f^3-12e^2f = 6e^2f(3f^2-2)
