Answer:
B. m<3 = 100°
C. m<2 + m<4 = 80°
Step-by-step explanation:
Given that n is parallel to m, the following are the measure of each numbered angles:
m<1 = 60° (vertical angles are congruent)
m<2 = 20° (corresponding angles are congruent)
m<3 = 180 - (m<CAB + m<1) (sum of ∆)
m<3 = 180 - (20° + 60°)
m<3 = 100°
m<4 = 60° (corresponding angles are congruent)
Therefore, the following statements are TRUE:
B. m<3 = 100°
C. m<2 + m<4 = 80°
180 - 130 = 50°
opposite sides add up to 180
An integer is a rational number; 1/2 is a rational ratio with a denominator of 1; 0.4545 is a rational decimal; 0.44 is a irrational decimal and 0 is a rational whole numbers.
<h3>What is the difference between a rational and a irrational number?</h3>
The category irrational number can be applied to numbers that cannot be expresses as ratios or fractions. This includes decimals that do not terminate and are not repeating such as 0.44454...
<h3>On the other hand, rational numbers will include different types of numbers such as:</h3>
Integers: This refers to numbers that are not expressed as fractions.
Rational decimals: This includes repeating decimals such as 0.4545...
Rational ratios: This includes numbers such as 1/2 or 1/4.
Rational whole numbers such as 0,1,2, etc.

$3.50×0.8=$2.80
$2.80×0.9=$2.52
The new price is $2.52
All you have to do is the price multiplied by the amount of kg. BUT make sure that they are both in the same units, in this case they are both in kilograms. So you do 7.25x20=$145
