7 as
a percentage of 20 just means what percentage of 20 is 7. To do this, we must
divide 7 by 20. This is how you answer this. If you do so, then you will get
0.35. This shows that it is 35%. Note that when you get a decimal number, then
you must multiply it by 100% to get the percentage equivalent of that number.
Therefore, 7 as a percentage of 20 is 35%.
Answer:
368 ounces
Step-by-step explanation:
since 16 ounces is 1 pound, multiply 23 by 16
Answer:
search up the lesson name on yt and then u will know
Step-by-step explanation:
The rate(speed) is 1 3/5
We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr
Substitute
4/5= 1/2t
Multiply 2 on both sides
2* (4/5)=(1/2)t * 2
8/5=t
We can simplify this to 1 3/5
a. Pentagon
Interior angle:
5 sides => form 5 triangles => central angle: 360 / 5 = 72°
interior angle = 2x
angles in every triangle: x => x + x + 72° = 180°
=> 2x = 180° - 72° = 108°
Answer 108°
Exterior angles = 360° / number of sides = 360° / 5 = 72°
Answer: 72°
b. 16 - gon
Interior angles: 2x
number of triangles = 16
central angle = 360 / 16 = 22.5°
interior angle 2x, where 180° - 22.5° + x + x => 2x = 180° - 22.5° = 157.5°
Answer: interior angle 157.5°
Exterior angles: 360 / 16 = 22.5°
Answer: exterior angles = 22.5°
c. Dodecagon
number of sides 12
central angle = 360° / 12 = 30°
interior angle, 2x => 30 + 2x = 180 => 2x = 180 - 30 = 150°.
Answer: interior angle = 150°
Exterior angle = 360° / number of sides = 360° / 12 = 30°
Answer: exterior angle = 30°
