Answer:
y = 43°
Step-by-step explanation:
The unknown angle x inside the quadrilateral is adjacent to 80° and sum to 180° , then
x = 180° - 80° = 100°
The sum of the 4 interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360°
y + 145° + 72° + 100° = 360° , that is
y + 317° = 360° ( subtract 317° from both sides )
y = 43°
Answer:
$0.38
Step-by-step explanation:
Since there are two cups in a pint so you divide 0.76 by 2
Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.
1800 + 500 = 2300 calories consumed Tuesday.
2300 - 100 = 2200 calories Wednesday.
(2200 - 1800)/2 = 400/2 = 200 calories
Answer:
A = 36 cm²
Step-by-step explanation:
Given
A = ( a + b)
substitute h = 12, a = 2 and b = 4 into the formula, thus
A = (2 + 4) = 6(6) = 36 cm²
