17 is the sum of 4 and one-third of a number. what is the equation and what is the number?
Answers
x = a number
17 = 4 + 1/3x. First subtract 4 from both sides.
13 = 1/3x. Divide each side by 1/3.
39 = x

The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. Which function could represent this situation?A. f(x ) = x – |42.67| B. f(x ) = |x| – 42.67 C. f(x ) = |42.67 – x| D. f(x ) = 42.67 – |x|

Answer:
0.7
Step-by-step explanation:
The probability that the number is in set A’ is the probability that a number is not in set A.
From the venn diagram attached below, they are two sets, set A and set B. Set A has 3 elements {15, 12 18}, Set B has 5 elements {12 18 10 14 16}.
The total number of elements in the universal set is 10 i.e {10 11 12 13 14 15 16 17 18 19}
therefore the number of elements in set A' is 7, i.e {10 11 13 14 16 17 19}.
the probability that the number is in set A’ = number of elements in set A'/number of elements in the universal set
probability that the number is in set A’ = 7 / 10 = 0.7

Distance S = [ (y2-y1)^2 + x2-x1)^2 ] ^ 0.5
x1 , y1 = 38 , 30
x2 , y2 = 14 , 20
Distance S = [ (20-30)^2 + (14-38)^2 ] ^0.5
= [ 10^2 + (-24)^2 ] ^ 0.5
= [ 100 + 576 ] ^ 0.5
= 676 ^ 0.5
= 26

Answer:
18.8 feet, 59.1 feet to the nearest tenth
Step-by-step explanation:
The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.
The diameter D = 2r where r is the radius of the circle
The circumference = 2Πr = ΠD where Π = 22/7
Given that the circular fountain has a radius of 9.4 feet
Its diameter = 2 × 9.4 feet = 18.8 feet
The circumference = 22/7 × 18.8 feet
=59.09 feet
≈ 59.1 feet to the nearest tenth
9.4 * 2 = 18.8
diameter is 18.8 feet
circumference =
c = 3.14 * 18.8
c = 59.032
circumference is 59 feet.

α = 5 / 8 = 0.625 rev / s²
Number of revolutions of the 1st part:
α · t² /2 = 0.625 * 8² / 2 = 20 rev.
The 2nd part:
α = 5/12 = 0.41667 rev/s²
5 * 12 - ( 0.41667 * 12² / 2 ) = 60 - 30 = 30 rev.
In total: 20 + 30 = 50 revolutions
