Answer: 410 square km
Step-by-step explanation:
The area of each of the triangles with their base on the 10 km side is , so their combined area is .
The area of each of the triangles with their base on the 12 km side is , so their combined area is .
The area of the bottom rectangular face is .
So, the total surface area is
Answer:
B. $18.00
Step-by-step explanation
160/4 divide 160 by 4 to see how much Miss Adams makes and hour
She makes $4 an hour
multiply this ($4) by her idle time (4.5) hours to get $18
Hi there
Part a
49.98−49.98×0.5
=24.99
Part b
49.98−10
=39.98
Hope it helps
The graph is attached.
Answer:
(-2.2, 4) and (8.2, 4)
Step-by-step explanation:
In an ellipse, there is a minor radius and a major radius.
Let major radius be = a
Let minor radius be= b
From the graph, we are given:
Major radius, a = 6
Minor radius, b = 3
Now, let's find the distance from the center to the focus using the formula:
Substituting values, we have:
≈ 5.2
We can see from the graph that center coordinate is (3, 4). Therefore, the approximate locations of the foci of the ellipse would be:
(3-5.2, 4) and (3+5.2, 4)
= (-2.2, 4) and (8.2, 4)
#1 is -32
#2 is -11
#3 is -5
#4 is 6
