2a) $6.00
20% of $30 is the same as 30 multiplied by .20
2b) the sale price is $6.00
Answer:14
Step-by-step explanation:
x-1/2=x/4+3 multiply left and right side of equation with 4 you get:
4x-2=x+12
------------------
4x-2=x+12
4x-3x=12+2
x=14
Answer: 16. C 17. A 18. A
19 You got this! There is only one answer with the correct radius squared!
Step-by-step explanation:
For the coordinates of the center, flip the signs in the parentheses.
For the "=output": in the equation, square the given radius.
Center: (-14.4) the signs in (x + 14)²+(y - 4)² are the opposites.
Radius given: 2 Square it to get the =4
Again using the Pythagorean Theorem:
h^2=x^2+y^2, where h is the hypotenuse of a right triangle and x and y are the side lengths. You are given that the hypotenuse is 34 ft and the base side is 16ft. Let h=34, x=16, and y=height, then you have:
34^2=16^2+y^2
y^2=34^2-16^2
y^2=1156-256
y^2=900
y=√900
y=30 ft
So the ladder will reach a spot 30 feet high on the building.
Cone volume= 285 ( the radius would be 5.5)
Cylinder volume =95 same radius as well
