The answer is D. Tell me if this works.
Answer:
Step-by-step explanation:
7d – 8 = 3d + 8
7d - 3d = 8 + 8
4d = 16
d = 16 /4
d = 4
Answer:
Step-by-step explanation:
Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant
In our case, for the left triangle,
Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get
Same difference with the right triangle. With the same calculations
Area = width x length
If the area is 48 and width is 6, you can do
Length = area/width
Length = 48/6
Length = 8
Perimeter = length x 2 + width x 2
Perimeter = 8x2 + 6x2
Perimeter = 16 + 12
Perimeter = 28 feet
Answer: x + 3x = 11
Step-by-step explanation:
Two cities A and B
Both cities receive 11 inches of rainfall in total
Amount of Rainfall in inches received by city A = x
Amount of Rainfall in inches received by city B = 3x
Therefore given the details above, total rainfall is best expressed using the equation ;
Rainfall in city A + Rainfall in city B = 11 inches
x + 3x = 11
