Answer:
3.17
Step-by-step explanation:
2.5/1.5 = 1.66667, 1.66667 (it goes on infinitely 1.6666 etc.)
1.66667 x 1.9 = 3.166666654, and when rounded to nearest tenth it is 3.17
Let
rA--------> radius of the circle A
rB-------> radius of the circle B
SA------> the area of the sector for circle A
SB------> the area of the sector for circle B
we have that
rA=5/2 ft
rB=9/2 ft
rA/rB=5/9-----------> rB/rA=9/5
SA=(25/36)π ft²
we know that
if Both circle A and circle B have a central angle , the square
of the ratio of the radius of circle A to the radius of circle B is equals to
the ratio of the area of the sector for circle A to the area of the sector for
circle B
(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->
<span>SB----------- > (81/25)*(25/36)------ > 81/36------
> 9/4π ft²</span>
the answer is
<span>the measure of the sector for circle B is (9/4)π ft²</span>
Answer:
1/6 is your answer :))
Step-by-step explanation:
There is 1 four out of 6 possible numbers = 1/6
Answer:
97, 485, 197
Step-by-step explanation:
<u>Given</u>:
- First number = a
- Second number = b
- Third number = c
<u>Then we have:</u>
- b = 5a
- c = 100+a
- a + b + c = 779
<u>Substituting b and c in the third equation:</u>
- a + 5a + 100+a = 779
- 100 + 7a = 779
- 7a = 779- 100
- 7a=679
- a= 679/7
- a = 97
- b= 5*97 = 485
- c = 100+ 97 = 197
Answer:
yes
yes is answer of this equation
