Answer:
w = 35
Step-by-step explanation:
The angle adjacent to 125° is
180° - 125° = 55°
The 3 angles on the straight line sum to 180° , that is
90 + w + 55 = 180
w + 145 = 180 ( subtract 145 from both sides )
w = 35

A temperature in degrees Fahrenheit is shown in expanded notation. ( 9 × 10 ) + ( 4 × 0.1 ) How is this temperature in degrees Fahrenheit written a numeral?
Answer:
90.4 degrees.
Step-by-step explanation:
(9 x 10) + (4 x 0.1)
= 90 + 0.4
= 90.4.
The Temperature in Fahrenheit is 90.4 F.
What is Expanded form?The division of numbers into groups according to place value, such as ones, tens, hundreds, thousands, ten thousand, and so forth, results in the expanded form of the number. The expanded version of the number is the one that is represented by the sum of each digit times its place value.
Given:
Expanded notation. ( 9 × 10 ) + ( 4 × 0.1 )
