The area of one window is 15 ft²
Step-by-step explanation:
Area of a trapezoid window can be calculated as ;
1/2(a+b) h where
a=outside edge length
b=inside edge length
h=length across
Given that ;
a=1 ft
b=5 ft
h=5 ft
Area= 1/2( 1+5)5
Area= 1/2 (6)5
Area=3*5 =15 ft²

Answer:
a) x = 69°
b) y = 69°
Step-by-step explanation:
a. Given that AB and CD are parallel lines, therefore:
x = 69° (alternate interior angles are congruent to each other)
b. y + 111° = 180° (consecutive interior angles are supplementary)
y = 180° - 111° (substraction property of equality)
y = 69°
If it moves 29.9 meters a day, then we need to find the total amount of days:
1000 days + 100 days = 1100 days
Since it moves 29.9m per day, we can write:
29.9m x 1100 which equals 32 890m
So it moved 32 890m
Answer:
The surface area A of a sphere:
A=4πr^2
r - the radius
r=30 m
A=4π×30 ^2 =4π×900=3600π [m ^2 ]
Surface area = 3600π [m ^2 ]
I think that all you need to do is multiply the 12% commission by the $9,000 worth of merchandise sold. 12% would equal 0.12. So 0.12 x 9,000 = $1,080.
