Answer:
-0.111c + 1 = 0.889c = c=1
Subtract 0.889c from both sides:
−0.111c+1−0.889c=0.889c−0.889c
−c+1=0
Subtract 1 from both sides.:
−c+1−1=0−1
−c=−1
Divide both sides by -1.:
-c/1 = -1/-1
Therefore, your answer is c=1
Answer:
Exponents first then multiplication then subtraction
Answer:882
Step-by-step explanation:5 percent of 840 is 42 so 840 plus 42
Answer:
Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:
Answer:
Therefore the value of x = 10 units
Step-by-step explanation:
Let label the Triangles first,
Δ ABC a right triangle at ∠ A =90°
Δ ADB andΔ ADC a right triangle at ∠ D =90°
Such that
AD = x
BD = 50
CD = 2
∴ BC = BD + DC = 50 + 2 = 52
To Find:
x = ?
Solution:
In right triangle By Pythagoras Theorem,
In right triangle Δ ADB andΔ ADC By Pythagoras Theorem we will have,
AB² = BD² + AD²
AB² = 50² + x² ..................equation ( 1 )
and
AC² = DC² + AD²
AC² = 2² + x² ...................equation ( 2 )
Now in right triangle Δ ABC,
BC² = AB² + AC²
Equating equation (1 ) and ( 2 ) and the given value we get
52² = 50² + x² + 2² + x²
∴ 2x² = 2704 - 2504
∴ 2x² =200
∴
Therefore the value of x = 10 units
