Answer:

Value of  43 – 10 ÷ 2 + [(7 + 3) • 3] is 68 .

Step-by-step explanation:

As the expression given in the question be as follow .

= 43 – 10 ÷ 2 + [(7 + 3) • 3]

It also written as

= 43 - 5+ [7\times 3+3\times 3]

= 43 - 5+ [21+9]

= 43 - 5+ [30]

What is 168.023 in expanded form using fractions
bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + \frac{2}{100} + \frac{3}{1000}

Step-by-step explanation:

Expanded form:

  • Is a way to write numbers to see the math value of the digits.
  • When numbers are separated into their place values and decimal places they can also form a mathematical expression.
  • Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + \frac{2}{10} + \frac{7}{100} = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = \frac{2}{100}

∵ Its thousandths digit is 3

∴ Its value = \frac{3}{1000}

∴ The expanded form of 168.023 = 100 + 60 + 8 + \frac{2}{100} + \frac{3}{1000}

Two men, 400 feet apart, observe a balloon between them it is the same vertical plane as they are. The respective angles of elev
slava [35]
The answer is 471 feet.

If A = man to left of balloon 
<span>B = balloon </span>
<span>C = man to right of balloon </span>

<span>∠BAC = 75°20' </span>
<span>∠BCA = 49°30' </span>
<span>∠ABC = 180 - 75°20' - 49°30' = 55°10' </span>
<span>AB = 400 ft </span>

<span>Now we have to find the value of x, which is the side opposite to angle of 75°20' </span>

<span>Using Law of Sines: </span>
<span>x/sin(75°20') = 400/sin(55°10') </span>
<span>x = 400 * sin(75°20') / sin(55°10') </span>
<span>x = 471.44 </span>
<span>x = 471 ft </span>
