Answer:
7.5
Step-by-step explanation:
you need to get the X alone so you multiply both sides by -0.5.
that leaves you with x=7.5

What is the sales tax rate if a $7,594 purchase will have $569.55 of sales tax added to it?
Answer:
0.075
Step-by-step explanation:
The sum of the number and three times its reciprocal is 79/10. Find the
number.
hi
so x + 3 (-x) = 79/10
x-3x = 79/10
-2x = 79/10
x = 79/10 / -2
X = 79/ 10 * -1/2
x = - 79/20
x = - 3.95

College Algebra Half Life Problem
Recently, while digging in Chaco Canyon, New Mexico, archaeologists found corn pollen that was 4000 years old. This was evidence that Native Americans had been cultivating crops in the Southwest centuries earlier than scientists had thought.
What percent of the carbon-14 had been lost from the pollen?
(half-life of carbon-14 = 5730)

A new truck costing $60,000 with a residual value of $6,000
it costs 13$ for admission to amusement park, plus 1.50$ for each ride.if you have a total of 35.50 to spend, what is the greatest number of rides you can go on
Answer:
Thus, the greatest number of rides I can go on is 15 rides
Step-by-step explanation:
I have $35.50 to spend for admission plus rides in the amusement park.
Admission costs $13. That leaves me with
$35.50 - $13 = $22.50
to spend on rides.
Considering each ride costs $1.50, we can find the maximum number of rides by dividing the remaining money by the cost per ride as follows:
$22.50 / $1.50 = 15
Thus, the greatest number of rides I can go on is 15 rides

Step-by-step explanation:
find and interpret the probability that exactly 13 of those surveyed feel the state of morals is poor
Complete question is;
In a recent poll, the Gallup Organization found that 45% of adult Americans believe that the overall state of moral values in the United States is poor. Suppose a survey of a random sample of 25 adult Americans is conducted in which they are asked to disclose their feelings on the overall state of moral values in the United States. Find and interpret the probability that exactly 13 of those surveyed feel the state of morals is poor.
Answer:
P(X = 13) = 0.1236 or 12.36%
This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor
Step-by-step explanation:
We are given;
Sample size; n = 25
Chance of success; p = 45% = 0.45
This question is a binomial probability distribution problem and the formula is;
P(X = x) = nCx × p^(x) × (1 - p)^(n - x)
probability that exactly 13 of those surveyed feel the state of morals is poor is;
P(X = 13) = (25C13) × 0.45^(13) × (1 - 0.45)^(25 - 13)
P(X = 13) = 5200300 × 0.00003102864 × 0.00076621787
P(X = 13) = 0.1236 or 12.36%
This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor

In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00. Find the probability of winning if you pick the number 30 and it comes up on the wheel. Round your answer to 3 decimal places. Answer:
Answer:
Step-by-step explanation:
Total out come is 38
Favorable outcome is 1
Probability is 1/38 ≈ 0.026
The probability of winning if you pick the number 30, and it comes up on the wheel, will be 0.026.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00.
Then the total number of the event will be
Total event = 38 {0, 00, 1, 2, …, 36}
Then the probability of winning if you pick the number 30, and it comes up on the wheel will be
Favorable event = 1 {30}
Then the probability will be
P = 1 / 38
P = 0.026

9x⁴-3x²+1
Does anyone know how to solve this question?
It would be really helpful if you'd help me.
thank you so much
Simplifying the equation:
We are given the bi-quadratic equation:
9x⁴-3x²+1
to factorise this equation, we will convert it to a quadratic equation and factor it from there
in the given equation, let x² = y
now, the equation looks like:
9y² - 3y + 1
Finding the Factors (in terms of y):
Using the quadratic formula: x = -b±√(b²-4ac) / 2a
replacing the variables in the equation
y = [-(-3) ± √[(-3)² - 4(9)(1)]]/2(9)
y= [3 ± √-27]/18
y = (1 ± √-3 / 6)
The 2 solutions are:
y = (1 + √-3 / 6) and y = (1 - √-3 / 6)
Finding the values of 'x':
Since y = x²:
x² = (1 + √-3 / 6) and x² = (1 - √-3 / 6)
taking the square root of both sides
x = √(1 + √-3 / 6) and x = √(1 - √-3 / 6)
As we can see, the given equation has complex roots and cannot be simplified further

it cost 13.80 for 5 tickets how much would it cost for 3 tickets
Answer:
$8.28
Step-by-step explanation:
So, first we must find the price per ticket so we do
13.80/5 = 2.76
So the $2.76 per ticket
So now all we do to find the price of three tickets we times the price per ticket by 3
2.76 x 3 = $8.28

Two hot air balloons.
Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles
Distance of Tasha's balloon is represented by function y = 8x + 20
x is independent variable so it would represent the time.
y is dependent so it represents the miles travelled.
Balloon one = (0, 30) <-- begins here and (2, 48)
Balloon two = (0, 20).
So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.
So Henry's balloon was farther form the town at the beginning.
Now let's find the slope/rate of change and compare then.
Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9
Tasha's balloon m: 8
9>8 Therefore henry was faster
