Answer:
Her son mowed more of the yard than Ms. Jones did.
32 percent of the yard still needs to be mowed.
Step-by-step explanation:
Find the LGM of 1/4 and 3/7 - that is 28
1/4 to 7/28 and 3/7 to 12/28
3/7 is more than 1/4
Her son mowed 43% of the yard or 7/28 of the yard or 1/4 of the yard.
Ms. Jones mowed 25% of the yard or 12/28 of the yard or 3/7 of the yard.
Together they mowed 68% of the yard or 19/28 of the yard.
They still have 32% of the yard left to mow, or 9/28 of the yard left to mow.
use sine law. x = 16.3cm
Step-by-step explanation:
Since triangle angles add up to 180 deg
angle F = 180 -87 -40 = 53
side EF/ sin (angle G) = side EG / sin (angle F )
EF / sin(87) = 13 / sin(53)
EF = 13/sin(53) × sin(87)
EF = 16.3cm
9(x-4)=9x-33
9x-36=9x-33
9x-9x-36=-33
-36=-33 which is impossible.
Then there are 0 solution.
Lets inaugurate the roots


Now coming to options

- π=3.141
- 5/2=2.50
- 2.1
Answer:
Angle BPQ = 64°
Step-by-step explanation:
4x + 12 +2x = 90
6x + 12 = 90
- 12 -12
6x = 78
x = 13°
BPQ = ((4(13) + 12)°
(52 + 12)°
64°
