soln,
2x+2 = 3x - 52 [vertically opposite angles]
or, 2 + 52 = 3x - 2x
therefore, x = 54°
Answer:
64/27
Step-by-step explanation:
Take the reciprocal of 3/8: 8/3
Multiply this number by 8/9: 8/9 * 8/3 = 64/27
Therefore, 8/9 ÷ 3/8 = 64/27
It would be 4650mm.
1cm=10mm
465(10)=4650
Answer: m^4
Step-by-step explanation:
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.
