Answer:
No not all of them.
Step-by-step explanation:
Triangles can be 2d meaning like a flat triangle.
Answer:
168 cm²
Explanation:
Lateral surface area of triangular prism: (perimeter of base) × height
Here given:
So, lateral surface area:
= (4 + 6 + 4) × 12
= 168 cm²
Answer:
11.2 cm
Step-by-step explanation:
Given that;
Arc Length Formula (if θ is in radians): l = ϴ × r
ϴ = angle subtended in radians
r= radius of the circle
l = 8cm × 1.4 radians
l= 11.2 cm
Answer:
C
Step-by-step explanation:
let's say the 18 was the 100 and x was the 20% of that 100, if they equal the same just take 20% of 18 (you will get 3.6)
Therefore is C : x/18 = 20/100.
The answer for the first question is D.
here's why: John goes 60 miles an hour so to go 240 miles is 4, and to 30 miles is 30 minutes. so that would mean it would take him 4.5 hours ( 4 hours and 30 minutes. )
The answer to the second question is C.
here's why: since each of the workers mow at the same speed, there's no need to worry about the 9. now you just need to divide 45 by 10 ( 4.5 ) to see how many lawns he mows in an hour ( 4.5 )
