Answer:
B
Step-by-step explanation:
It seems like the answer would be B since 0.4 x 0.9 = 0.36 and the intersection for answer choice B is 36 grid blocks.
Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
= 
× 14 × 10
= 70
Area of a semicircle = 
( r is the radius)
Radius = half of diameter = 
= 7m
Area of semicircle = 
= 77 ( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
Answer:
Height of slide = 5 feet (Approx.)
Step-by-step explanation:
Given:
Length of slide = 12 feet
Angle of depression = 25°
Find:
Height of slide
Computation:
Length of slide = Hypotenuse
Height of slide = Perpendicular
Using trigonometry function;
Sin θ = Perpendicular / Hypotenuse
Sin 25 = Height of slide / 12
0.422 = Height of slide / 12
Height of slide = 12 x 0.422
Height of slide = 5.064
Height of slide = 5 feet (Approx.)
Answer:
A: 30 m
B: 14 boxes
C: $596.40
D: $477.12
Step-by-step explanation:
A: 6*4.2 = 25.2. 3.2*1.5 = 4.8. 25.2 + 4.8 = 30.
B: 30/2.15 = 13.95, which rounds to 14.
C: 14*42.60 = $596.40
D: 20% off 100% = 80%, which is equal to 0.8. 596.40*.8 = $477.12.
Hope it helps you!! :)
