I think the answer is 13.5. △DEF is 1.5 times bigger than <span>△ABC</span>

Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5

Convert the angle 0=228 degrees to radians

miv72 [106K]

Answer:

$\dfrac{19}{15}\,\text{radians}=1.2\overline{6}\,\text{radians}$

Step-by-step explanation:

θ = 228° = (228°)×(π/180° radians/degree) = 228/180 radians

= 19/15 radians

≈ 1.266...(repeating) radians

Identify the digit with the given place value in number 173.514 hundredths

Llana [10]

Answer: We are given the number 173.514

Each of the digits in this number has the following place value:

$\begin{gathered} 1\rightarrow\text{ Hundreds} \\ 7\rightarrow\text{ Tens} \\ 3\rightarrow\text{ Ones} \\ \text{.}\rightarrow\text{ Decimal Point} \\ 5\rightarrow\text{ Tenth} \\ 1\rightarrow\text{ Hundreth} \\ 4\rightarrow\text{ Thousandth} \end{gathered}$

Secondly, We have to identify the numbers in digit 185.712

$\begin{gathered} 1\rightarrow\text{ Thousand} \\ 8\rightarrow\text{ Hundred} \\ 5\rightarrow\text{ Tens} \\ \text{. Decimal point} \\ 7\text{ }\rightarrow\text{Thenth} \\ 1\rightarrow\text{ Hundreth} \\ 2\text{ }\rightarrow\text{ Thousandth} \\ \end{gathered}$

A machine takes 5.4 hours to make 9 parts. At that rate how many parts can the machine make in 25.8 hours

Sliva [168]

$\frac{5.4}{9} = \frac{25.8}{x}$ Cross multiply.

5.4x=9*25.8

5.4x=232.2 Divide both sides by 5.4

x=43
