A hockey player is offered two options for a contract: either a base salary of 50,000 and 1000 per goal, or a base salary of 40,000 and 1500 per goal. How may goals must he score in order to make the same money as the first contract?
Final answer:
The hockey player must score 20 goals to make the same money as the first contract.
Explanation:
In order to make the same amount of money as the first contract, the hockey player must calculate the number of goals required. Let's assume the player needs to score 'x' goals.
For the first contract, the total salary would be 50000 + 1000x. For the second contract, the total salary would be 40000 + 1500x.
Equating the two salaries, we get:
50000 + 1000x = 40000 + 1500x
Subtracting 1000x from both sides, we get:
50000 = 40000 + 500x
Subtracting 40000 from both sides, we get:
10000 = 500x
Dividing both sides by 500, we get:
x = 20
So, in order to make the same money as the first contract, the player must score 20 goals.
What is the solution to the system of equations? 6x-3y=3 and y=2x-4
Answer:
empty set or have no soln
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 2x + 4....this is just a matter of substitution...so sub in 2x + 4 for y back into the other equation
6x - 3y = 3
6x - 3(2x + 4) = 3......distribute the -3 thru the parenthesis
6x - 6x - 12 = 3 ...combine like terms
-12 = 3 (incorrect)
these equations have NO SOLUTION because they are parallel lines
You have 6 red marbles, 7 green and 2 blue marbles. What is the probability of pulling a red marble and then without replacing the first marble grabbing a green marble?
Answer:
P(red marble) = 6÷15
Step-by-step explanation:
First, we add all of it we get 15.
Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.
Here the favorable outcomes to red is 6,and the total outcome is 15.
So it is 6÷15.
Now we took one marble. And kept it away.
Now the total number of outcomes are 15-1=14
Now the favorable outcomes for green is 7,snd total outcomes are 14.
So the probability is 7÷14.
Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.

The numbers represented by variables w and y on the number line are integers.
If w < x < y, under which of the following conditions could the expression x > 2 be true? Select TWO that apply.
A
when y = 6 and w = 2
B
when y = 4 and w = –1
C
when y = 2 and w = 0
D
when y = 0 and w = –2
E
when y = –1 and w = –4
Option A) when y=6 and w= 2, Option B) when y=4 and w=-1 are the TWO correct choices.
Step-by-step explanation:
The given inequality is w<x<y and x>2.
step 1: let us assume that x=3, since it is given that x>2.
step 2: substitute the value of x=3 and each options in the inequality
step 3: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).
option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).
option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).
option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).
option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).

Answer:
The standard deviation is 2.6076809621.Step-by-step explanation:
The set of values are 2, 4, 7, 8, 9.
The mean of these values are [tex]\frac{2 + 4 + 7 + 8 + 9}{5} = \frac{30}{5} = 6[/tex].
The mean of the squares of the differences of these numbers and the mean is [tex]\frac{(6 - 2)^{2} + (6 - 4)^{2} + (6 - 7)^{2} + (6 - 8)^{2} + (6 - 9)^{2}}{5} = \frac{(4)^{2} + (2)^{2} + (-1)^{2} + (-2)^{2} + (-3)^{2}}{5} = \frac{34}{5} = 6.8[/tex].
In order to get the value of the standard deviation, we need to square-root the value of 6.8.
Hence, the standard deviation of the data set is [tex]\sqrt{6.8} = 2.607680962081[/tex] ≅2.6076809621.
Answer:
Correct answer is 2.9.
Took the test.
Write as an equation: The sides of a triangle are 7, x and (x + 1). The perimeter is 30.
A. 30 =7+ (x+1)
B. 30 - 7 = 2x
C. 30 = 7 + 2(x + 1)
D.30 = 8+2x
Answer:
d
This is because 7+x+1=30 (this is the equation btw).
You combine the like terms so you get 30=8+2x (7+1 and x+x)
do the equation so you get:
30=8+2x
-8 -8
22=2x
divide both sides by 2
11=x
Answer:
D
Step-by-step explanation:
Perimeter = addition of all sides
30 = 7 + x + x + 1
30 = 8 + 2x
Collecting like terms
30 - 8 = 2x
22 = 2x
Dividing by 2
22/2 = 2x/2
11 = x

Find The original price of a motorbike if you got a 10% discount and paid a final price of $2160 for it
Answer:
2376
Step-by-step explanation:
2160×1.10
i believe it is this
Final answer:
The original price of the motorbike is calculated by dividing the final price of $2160 by 0.9, which represents the 90% price paid after a 10% discount. The original price of the motorbike was $2400 before the discount was applied.
Explanation:
The question asked us to calculate the original price of a motorbike before a 10% discount was applied and the final price came down to $2160. To do this, we recognize that the final price ($2160) is 90% of the original price because a 10% discount was given. Thus, if we let the original price be 100%, we can find it by dividing the final price by 0.9 (which represents 90%).
Here's the step-by-step calculation:
Express the discount as a decimal: 10% = 0.1.
Determine the percentage of the original price paid: 100% - 10% = 90% = 0.9.
Calculate the original price: Original Price = Final Price / 0.9.
Substitute the known value: Original Price = $2160 / 0.9.
Perform the division to find the original price: Original Price = $2400.
The original price of the motorbike was therefore $2400 before the discount.

X/3 is equivalent to 1/3X
Answer:
This is true
Step-by-step explanation:
When looking at x itself it is just ONE x. 1x=x, the 1x isn't necessary to have so it is shown as x. So looking at x/3 you could say it is also 1x/3 which would still be the same if it were 1/3x. Both would still be considered one-third OF x.
The answer is "[tex]3x=3x[/tex]"
Equating:
[tex]\to \frac{x}{3} = \frac{1}{3}x\\\\x=?[/tex]
Cross multiplying the given expression:

Answer:
Part A: For no solution ⇒ 3x + 9 + 4x + x = 8x + 0
Part B: For one solution ⇒ 3x + 9 + 4x + x = 0 * x + 1
Part C: For infinitely many solutions ⇒ 3x + 9 + 4x + x = 8x + 9
====================================
Step-by-step explanation:
Part A:
3x + 9 + 4x + x = 8x
8x + 9 = 8x ⇒ Subtract 6x from both sides,
9 = 0 which is absurd and hence the equation has no solution.
=====================================
Part B:
3x + 9 + 4x + x = 0 * x + 1
∴ 3x + 9 + 4x + x = 1
8x + 9 = 1 ⇒ Subtract 9 from both sides.
8x = 1 - 9 = -8 ⇒ Divide both sides by 8.
x = -1 ⇒ this is the only solution.
======================================
Part C:
3x + 9 + 4x + x = 8x + 9
8x + 9 = 8x + 9
Subtract 8x from both sides,
9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

a scuba diver descended at a rate of 2 1/4 per second. If 0 represents the surface of the water and distances below the surface are negative,which expression represents one way to calculate the location of the diver after 12 1/2 seconds?
To calculate the location of the diver after 12 1/2 seconds, use the formula: location = initial location - (rate of descent * time). The location of the diver after 12 1/2 seconds is -28.
Explanation:To calculate the location of the diver after 12 1/2 seconds, we can use the formula: location = initial location - (rate of descent * time). Since the diver is descending at a rate of 2 1/4 per second, we can plug in the values to calculate their location after 12 1/2 seconds.
Initial location: 0 (surface of the water)
Rate of descent: 2 1/4 per second
Time: 12 1/2 seconds
Using the formula, we have: location = 0 - (2 1/4 * 12 1/2)
Calculating the expression, we find that the location of the diver after 12 1/2 seconds is -28.

the function f (x) = 1n ( x ) has been transformed so that there is a vertical asymptote at x= -3 what is the equation of the resulting function g ( x) ?
A: g (x) = 1n (x)-3
B: g (x) = 1n (x) + 3
C: g (x) = 1n ( x-3)
D: g = 1n ( x +3)
Answer:
C
Step-by-step explanation:
The equation of the function g(x) after the transformation is g(x) = kn(x - 3).
What are Vertical Asymptotes?A vertical asymptote of a function is the vertical line x = c such that the function tends to approach to infinity as the value of x approaches c.
Given a function f(x) = = ln (x).
The vertical asymptote of the logarithmic function is x = 0.
If the vertical asymptote of the new function is x = 3, this means that the function is shifted to the right by 3 units.
When f(x) is shifted to right by k units, new function is f(x - k).
So the function g(x) is,
g(x) = f(x - 3) = ln (x - 3).
Hence the correct option is C.

At a football game, a vender sold a combined total of 213 sodas and hot dogs. The number of sodas sold was two times the number of hot dogs sold. Find the
number of sodas and the number of hot dogs sold.
142 sodas and 71 hot dogs are sold
Solution:
Let "a" be the number of sodas sold
Let "b" be the number of hot dogs sold
At a football game, a vender sold a combined total of 213 sodas and hot dogs
Therefore,
number of sodas sold + number of hot dogs sold = 213
a + b = 213 ------------ eqn 1
The number of sodas sold was two times the number of hot dogs sold
Number of sodas sold = two times the number of hot dogs sold
a = 2b ---------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
2b + b = 213
3b = 213
b = 71
Substitute b = 71 in eqn 2
a = 2(71)
a = 142
Thus 142 sodas and 71 hot dogs are sold
