Answer:
8 cm
Step-by-step explanation:
(See the image attached for details)
- The blue segment measures 15 cm
- The green segment measures 7 cm
- The green and yellow segment when added form the blue segment
- So: ? + 7 = 15
Solve:
? + 7 = 15
Subtract 7 on both sides:
? + 7 = 15
-7 -7
? = 8 cm
Therefore, the yellow segment, or the missing side length, measures 8 cm.
Answer:
39.5% (3 sf)
Step-by-step explanation:
Area of 1 window: 4×5 = 20 ft²
2 windows: 3×20 = 60ft²
Area of the wall: 8×19 = 152 ft³
Percentage of window area:
60/152 × 100 = 39.47368421%
= 39.5% (3 sf)
So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.

Answer:
4/3
Step-by-step explanation:
-3y + 4x = -6
-3y = -6 -4y
slove for Y
y = -6/-3 -4/-3 x
Y = -2 +4/3x
Y = 4/3 x -2
Y = 4/3 x -2
so slope or gradient is coefficient of x
4/3 is gradient.
