Step-by-step explanation:
There is 6 sides on a rectangular prism
the top would be 6 x 4 = 24 and same for the bottom then I'll do the left amd right sides those are 20 and the front and back sides are 30 so I add all the sides so...
30 + 30 + 20 + 20 + 24 + 24 = 148
so 148 is our answer
Answer:
Hector's kite is 61.84 feet from the ground.
Step-by-step explanation:
The angle of elevation of the kite is 42°15’30” when converted to decimals, it is 
≅ 
Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,
Sin θ = 
Sin = 
⇒ x = 86 x Sin
= 86 x 0.6725
= 57.835
x ≅ 57.84 feet
The height of Hector's kite from the ground = x + 4
= 57.84 + 4
= 61.84 feet
Answer: 58.1 pounds
Step-by-step explanation:
Use proportion to solve peroblem.
30:249=7:x
30x=249*7
x=249*7/30
x=58.1 pounds
Lanzetta Elem. raised 5358....round to 5,000
Lantana Mid. Sch raised 2834....round to 3,000
Atlanta High Sch. raised 4132...round to 4,000
they need 14,000...they have (5,000 + 3,000 + 4,000) = 12,000....so they will need (14,000 - 12,000) = 2,000 more....keep in mind, these are estimates...not exact answers
