Answer:
78.
Step-by-step explanation:
the reason this is 78 is because you divide 6 by two then get 3. 3*20=60. 30% of 20 is 6. 6*3 is 18 plus 60=78
Let x be the length.
Then the perimeter is given by the formula : 2(20+x)=40+2x.
Area of the dance floor:
Answer:
0.875
Step-by-step explanation:
P(H=0) = 0.125
P(H=1) = 0.375
P(H=2) = 0.375
P(H=3) = 0.125
P(H<3) = P(H=0) + P(H=1) + P(H=2)
P(H<3) = 0.125 + 0.375 + 0.375
P(H<3) = 0.875
We are given that the hall has a rectangular shape.
Area of rectangle can be calculated using the following rule:
Area of rectangle = length * width
We are also given that:
Area = 7400 square feet
length = 82 feet
Substitute with the givens in the above equation to get the width as follows:
Area of rectangle = length * width
7400 = 82 * width
width = 7400 / 82
width = 90.24390244 feet
Answer:
Cabin is 567 yards away...
Step-by-step explanation:
The angle 21.2° is also the angle of the upper interior angle of the triangle (near the cabin)
Use the tan function:
opposite = 220 yards
adjacent = x
tan(21.2°) = (opposite / adjacent)
tan(21.2°) = 220 yards/x
x * tan(21.2°) = 220 yards
x = 220 yards/ tan(21.2°)
x= 220/ 0.388
x = 567 yards.
Cabin is 567 yards away...
