Which of the following describes a situation in which the total distance a baseball player travels is 0 meter from his starting point? (5 points)
The player runs 3 meters forward and then runs 3 meters in the opposite direction.
The player runs 4 meters forward and then runs 3 meters in the opposite direction.
The player runs 3 meters forward and then runs 0 meter in the opposite direction.
The player runs 3 meters forward and then runs 4 meters in the opposite direction.
Answers
The total distance a baseball player travels is 0 meter from his starting point in the first case when he runs 3 meters forward and then runs 3 meters in the opposite direction.
What is distance ?
A measurement of how far away two things or points are might be quantitative or occasionally qualitative.
If an object covers the same distance in the forward and opposite direction, it will cover 0 meter from his starting point.
It happens because when it covers a distance say 5 Km in forward direction and then, when it goes in the opposite direction with equal distance, it reaches to its starting point from where it was started.
Hence, If the player runs 3 meters forward and then runs 3 meters in the opposite direction, h will be at his starting point or we can say, he will cover 0 meter from his starting point.
However, in all other cases, the distance is not equal in both forward and opposite direction.

Penelope goes out to lunch. The bill, before tax and tip, was $16.05. A sales tax of 3% was added on. Penelope tipped 18% on the amount after the sales tax was added. How much tip did she leave? Round to the nearest cent.
Answers
Answer:
2.98
Step-by-step explanation:
First find 3% of 16.05 which is 0.48.
Then add 0.48 to 16.05 which is 16.53.
Then multiply .18 by 16.53 which gets you 2.98
Hope it helps
Answer:
To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:
Sales tax = 0.03 x $16.05 = $0.48
To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:
Total bill = $16.05 + $0.48 = $16.53
To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:
Tip = 0.18 x $16.53 = $2.98
Rounding to the nearest cent, Penelope left a tip of $2.98.

D) none, because C and D are not congruent
Step-by-step explanation:

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 65% salt and Solution B is 90% salt. She wants to obtain 150 ounces of a mixture that is 80% salt. How many ounces of each solution should she use?
Answers
The amount of solution A and B required are 60 and 90 ounces respectively.
Creating simultaneous equations for the problem:
Mass of solution A = a
Mass of solution B = b
a + b = 150 _____(1)
0.65a + 0.90b = 150×0.80
0.65a + 0.90b = 120 __(2)
From (1)
a = 150-b ____(3)
substitute (3) into (2)
0.65(150-b) + 0.90b = 120
97.5 - 0.65b + 0.90b = 120
0.25b = 120-97.5
0.25b = 22.5
b = 22.5/0.25
b = 90
a = 150 - b
a = 150 - 90
a = 60
Therefore , 60 ounces of solution A and 90 ounces of solution B is required.

Let's use the variable L to represent the length and W to represent the width.
If the perimeter is 600 ft, we have:
\(\begin{gathered} P=2L+2W\\ \\ 2L+2W=600\\ \\ L+W=300 \end{gathered}\)The width is half the length, so we have:

Answers
The absolute value inequality for all the points that line from distance 0 to less than 9 is |x|<9. The absolute value inequality for all the points that line from distance 0 to greater than 9 is |x|>9.
Inequality is a concept used in mathematics that helps to understand the relationship between two variables. These two variables are not equal and are not related using equal to sign. The symbols used in inequalities are >, <, ≥, and ≤.
The inequality for the points that lie from 0 to less than 9 is written as -9<x<9. Here, the distance is from 0 to less than 9 and any point that lies between these distances is denoted by x. Then, the absolute value inequality for the first condition is written as |x|<9.
The inequality for the points that life from 0 to greater than 9 is written as x>9 or x<−9. Here also the distance is from 0 to greater than 9 and any point that lies between these distances is denoted by x. Then, the absolute value inequality for the second condition is written as |x|>9.

Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast.
Answer: the July forecast is 15
Step-by-step explanation:
Given that;
Month Demand Weights
January 12
February 11
March 15
April 12 0.10
May 16 0.30
June 15 0.60
July ? ?
Formula for calculating weighted moving average is
Ft = w1A_t-1 + w2A_t-2 ............+ wnA_t-n
w1, w2, wn is the weight assigned to the period t-1, t-2, t-n respevtively
A_t-1, A_t-2, A_t-n is the demand period t-1, t-2, t-n respevtively
and n is the total number prior periods in the forecast.
so we just substitute our values into the equation
Forecast(July) = (15 × 0.6) + (16 × 0.30) + ( 12 × 0.10)
= 9 + 4.8 + 1.2
= 15
Therefore the July forecast is 15
If -9x(x + A) + 2 = (Bx + 2)(3x - 1) + 4, find the constants A and B.I am stuck at the step of solving B,can you help me?write down you steps and answer please
Answers
Answer:
A = -1
B = -3
Step-by-step explanation:
you need to do all the multiplication on both sides and then simply compare the factors of the various powers of x.
so,
-9x² - 9×A×x + 2 = 3×B×x² + 6x -Bx - 2 + 4
-9x² - 9×A×x + 2 = 3×B×x² + (6-B)x + 2
the x-less constants 2 = 2 are correct. now we need to compare the factors for the other parts of x.
we have left and right only one expression of x²
-9x² on the left
3×B×x² on the right
therefore,
-9 = 3×B
=> B = -3
otherwise the equation would not be correct for all values of x.
the only other parts remaining are
-9×A×x = (6-B)x = (6 - -3)x = (6+3)x = 9x
=>
-9×A = 9
-A = 1
A = -1
remember, all parts of the left and of the right side must be equal for the equation to be true in all cases.

The width of a rectangular parking lot is 53 ft less than its length. Determine the dimensions of the parking lot if it measures 250 ft diagonally.
Answers
Answer:
The dimension of the lot is 201.28 ft by 148.28 ft
Step-by-step explanation:
Given;
diagonal of the parking lot, d = 250 ft
let the length of the parking lot = L
the width, W = L - 53
The diagonal of the lot, length of the lot, and width of the lot form a right triangle.
Apply Pythagoras theorem to determine the length, L
L² + W² = 250²
L² + (L - 53)² = 250²
L² + L² - 106L + 2809 = 62,500
2L² - 106L + 2809 - 62,500 = 0
2L² - 106L - 59,691 = 0
this forms quadratic equation; a = 2, b = -106 and c = -59,691
\(L = \frac{- b \ \ +/- \ \ \sqrt{b^2 - 4ac} }{2a} \\\\L = \frac{- (-106) \ \ +/- \ \ \sqrt{(-106)^2 - 4(-59691 \times 2)} }{2(2)}\\\\L = \frac{106 \ \ +/- \ \ \sqrt{488764} }{4} \\\\L = \frac{106 + 699.12}{4} \\\\L = 201.28 \ ft\)
The width, W = 201.28 - 53
W = 148.28 ft
