Answer:
The area (A) of a triangle varies jointly as its ba
se (b) and height (h). If its base is 8 inches and i
ts height is 7 inches, it has an area of 28 square
inches. Find the base if its height is 5 inches an
5
d its area is 16 square inches.
Formulate the equation of variation.
Step-by-step explanation:
The mean, because the data distribution is skewed to the right
X+5 = -2x + 12
-5 -5
x = -2x + 7
+2x +2x
3x = 7
x = 2 1/3
y = x + 5
y = 2 1/3 + 5
y = 7 1/3
Answer:
40 cm
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, simplifying gives
4 =
Multiply both sides by (x + 2)
4(x + 2) = 48 ( divide both sides by 4 )
x + 2 = 12 ( subtract 2 from both sides )
x = 10
Hence
width = 4x = 4 × 10 = 40
Answer:
x = 20
Step-by-step explanation:
Two lines are parallel. So, alternate interior angles are congruent.
x +8 + 6x - 58 = 90
7x - 50 = 90
7x = 90 +50
7x = 140
x = 140/7
x = 20
