Answer:
86
Step-by-step explanation:
Radius=Circumference/Pi
135.02/3.14=43
Diameter=2r
43x2=86
5x + 3 is a linear equation in one variable
Answer:
The correct answer is A. 167 milliliters of 7% solution and 333 milliliters of 4% solution and here is how:
If x is the number of milliliters of the 7% saline solution and y is the number of milliliters of the 4% saline solution then add up to 500 milliliters total, so x + y = 500.
and if we do
x + y = 500
x = 500 - y
0.07x + 0.04y = 25 (substitute 500 - y for x)
0.07(500 - y) + 0.04y = 25
35 - 0.07y + 0.04y = 25
-0.03y + 35 = 25
-0.03y = -10
y = 333.333...
y = about 333
x = 500 - y = 500 - 333 = 167
Then you know why the answer is A.
Step-by-step explanation:
Answer:
a is adjacent, b is opposite, c is the hypotenuse
Step-by-step explanation:
see the attached figure to better understand the problem
In the right triangle XYZ we have
The side a and side b are the legs and the side c is the hypotenuse (the greater side)
The side a is the adjacent side to angle Y and is the opposite side to angle X
The side b is the opposite side to angle Y and is the adjacent side to angle X
The side c is the hypotenuse
The sum of the angles X and Y is equal to 90 degrees because are complementary angles
therefore
a is adjacent, b is opposite, c is the hypotenuse
