The least number of acute angles that a triangle can have is 2.
Let imagine you had 1 acute angle and 2 other angles that were non-acute (90° or higher)
a less than 90°
b less than 90°
c less than 90°
All the angles in a triangle add up to 180° (i.e) a + b + c = 180°
Since b and c are 90° or higher, that requires a to be negative. But we cannot have a negative angle, so there is no way to create a triangle with 1 (or fewer) acute angles.

Answer: 364 Laps
Step-by-step explanation:
1. $2.75 x 6 = $16.5
2. $1000 = 363.6 but it has a 6 so we add 1 more lap so 364 Laps in total

Answer:
y=4/3 x -5/3
Step-by-step explanation:
Please see attached picture for full solution.
A. if u unfold a cylinder, it is a circle, a rectangle, and a circle.
Find the area of those
to find the area of the circle, you need the radius.:
14/2= 7
To find the area of a circle, it is 3.14*r^2
=3.14*49
= 1538.6
Now you have to multiply it by 2 because there are two circles: 3077.2
Now find the area of the rectangle:
To find the area, you have to have the height (20cm) and the width of the rectangle/the circumference of the circle.
To find the circumference: 2*3.14*r(7)
= 2*3.14*7
=43.96
Now that you have that, you can find the area
43.96*20
=879.2
Now you add both products together
879.2+ 3077.2
=3956.4cm^2
B. divide 3956.4 by 3
=$1318.8
C. volume of cylinder: 3.14*r(7)^2h(20)
calculate that you get
3077.2
