To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
_______________
___ ____
(rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
So, your final answer would be (3.29, 4.87).
Answer:
Blue Triangle.
Step-by-step explanation:
Using the area formula for a triangle, the pink triangle has an area of 0.5×54×33 in² or 891 in². The blue triangle has an area of 0.5×56×39 in² or 1092 in².
Answer:
80.7 inches
Step-by-step explanation:
circumference = 2 * pi * r
2 * pi * r = 507 inches
r = (507 inches)/(2 * pi)
r = (507 inches)/(2 * 3.14159)
r = (507 inches)/(6.2832)
r = 80.7 inches
The correct answer is C "never."
The hypotenuse in a 30-60-90 triangle is the shorter leg doubled. So, it's 2x where x is the shorter leg.
In fact, the square root of two is not used to calculate any other sides in a 30-60-90 triangle. The shorter leg is x, the medium leg is x√3, and the hypotenuse is 2x.
