Answer:
The price of 1 pound of apple = $ 3
The price of 1 pound of berries = $ 8
The price of 1 pound of cherries = $ 5
Step-by-step explanation:
Let the price of 1 pound of apple be x
The price of 1 pound of berries be y
The price of 1 pound of cherries be z
So,
2 x + y + 4 z = 38 --------------1
3 x + 2 y + 2 z= 35 -------------------2 (Corrected from source)
5 x + 3 y + 2 z = 49 ------------3
Solving the equations, we get that:
x = 3, y = 8, z = 5
Answer:
49π
Step-by-step explanation:
The area for the formula of a circle is πr^2, where r is for radius. A radius is half of the diameter, which in this case is 14. 14/2 = 7, so the radius is 7. π(7)^2 = 49π.
Answer:
0
Step-by-step explanation:
tan 5
π
Remove full rotations of 2
π until the angle is between 0 and 2
π
. tan π
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant. tan 0 The exact value of tan 0 is 0
. Multiply
1 by 0
