C x -300 is the expression that represents the price of the television set after the instant rebate is applied and before the tax is applied
We are given that an expression models the final price of television set with an instant rebate in a state that charges a sales tax.
0.07x+(x-300)
The sale tax in on the original price .
We have to find an expression that represents the price of the television set after the instant rebate is applied but before the tax is applied.
Let x be the original price of television.
Instant rebate is subtracted from original price x.
Then , the cost of the television set=x-300
In the given expression 0.07 x is sales tax. where tax is 7 % on the original price x.
Sales tax is added to the price of television set.
Hence, option C is true and answer is C x -300

Alice, raul, and jane are baking cookies together, alice brought 2.5 cups of flour, raul brought 1 1/4 cups of flour and jane brought 3/4 cups of flour. how many cups of flour they have all together? show all work.
The total cups of flour Alice, Raul and Jane have altogether is equal to 6.
We can determine the number of cups of flour they have all together by the addition of the fractions brought by each one of them.
First, we convert the decimal value of 2.5 into fraction form;
2.5 = 2.5/1
Multiplying and dividing both sides by 10;
25/10 = 5/2
Now we add the fractions as follows;
Total number of cups of flour = 5/2 + 11/4 + 3/4
We Multiply 5/2 by 2 to get the same denominator as the other values;
5×2 / 2×2 = 10/4
10/4 + 11/4 + 3/4 = 6
Therefore, the total number of cups of flour they have altogether is calculated to be 6.

Select the better deal in the pair. Then give the unit rate for the better deal.
$56/25 gal or $31.05/15 gal
The better deal of the given pair is $31.05/1. The unit rate is $2.07.
What is the better deal?The better deal is the deal that has the lower unit rate. Unit rate is the price per gallon. The unit rate can be determined by dividing the total cost by the total gallons bought.
Division is the operation that is used in mathematics to determine the quotient of two or more numbers. Division entails grouping a number into groups using another number. Other operations used in mathematics are addition, multiplication and subtraction.
Unit rate = total cost / number of gallons
$56 / 25 = $2.24
$31.05 / 15 = $2,07

the number of people arriving for treatment at an emergency room can be modeled by a poisson process with a rate parameter of five per hour. what is the probability that exactly four arrivals occur during a particular ""half an hour""?
There is a 0.087 = 8.73% chance that four arrivals will occur at the same half-hour.
What is defined as the Poisson's distribution?The Poisson is a discrete distribution that calculates the likelihood of a given number of events occurring in a given time period.The probability that X is the number of successes of a random variable in a Poisson distribution is given by the following formula: P(X = x) = (e∧(-μ)× μˣ) / x!In which case,
x represents the number of successes.
The Euler number is e = 2.71828 = 2.72
μ is the average over the given time interval.
With a rate parameter of five per hour, the Poisson process is used.
So, μ = 5
The likelihood of exactly four arrivals occurring at the same time;
This is known as P(X = 4).
Put the values in the formula;
P(X = x) = (e∧(-μ)× μˣ) / x!
P(X = 4) = (2.72∧(-5)× 5⁴) / 4!
Simplifying the equation;
P(X = 4) = 0.08736
P(X = 4) = 8.73%
0.087 = 8.73% chance that exactly four arrivals happen during a specific half -hour.

assume that your compute completes a 5000 equation back substitution in 0.005 seconds. use the approximate operation counts n 2 for back substitution and 2n 3/3 for elimination to estimate how long it will take to do a complete gaussian elimination of this size.
In linear equation, 17 seconds it will take to do a complete gaussian elimination of this size.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Given that your computer completes a 5000 equation back substitution in 0.005 seconds.
then here Work is: n = 5000 and its rate is = (n2) / 0.005 = 5000000000
and Given formula : The approximate operation counts = ((2n^3)/3) = (2.0 * (n3)) / 3.0 = 83333333333.33
then we can found time = operations / rate = 83333333333.33/5000000000 = 16.67 = 17 seconds

2|x + 3|+1>3
Number line with open circles on -4 and -2, with shading in opposite directions.
Solution:Given: 2 |x + 3| +1 > 3 absolute value inequality.
We must solve and graph the following absolute value inequality:
2 |x + 3| +1 > 3
Take a look at the following absolute value inequality: 2 |x + 3| +1 > 3
We have to apply absolute rule:
If |u| > a , a > 0 then u < -a or u > a.
2|x + 3|+1 < -3 or 2|x + 3|+1 >3
Consider inequality first.
2|x + 3|+1 < -3
When we subtract 1 from both sides, we get,
2|x + 3| +1 -1 < -3 -1
Simplify,
2 |x + 3| < -4
We get by dividing both sides by two,
(2|x + 3|)/2 < -4/2
|x + 3| < -2
There is no solution for x ∈ R.
Now consider the second inequity.
2|x + 3|+1 >3
When we subtract 1 from both sides, we get,
2|x + 3|+1 - 1 >3 - 1
Simplify,
2|x + 3| >2
We get by dividing both sides by two,
(2|x + 3|) / 2 >3/2
|x + 3| > 1
x + 3 < -1 or x + 3 >1
x < -4 or x > -2
As a result, we have the solution to the absolute value inequality:
2|x +3|+1 > 3 as

The speed limit on a road is listed at 65 miles per hour. The car’s speedometer reads 63 miles per hour. Is it possible that this car is going over the speed limit?
It is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.
As given in the question,
Maximum error on the reading of speedometer =1.6%
Speed limit on a road is 65 miles per hour
Reading of a speedometer = 63 miles per hour
As per the error in the speedometer it can be more or less by 1.6%
To check speed limit
If it more
Speed limit = 63 + (1.6% of 63)
= 63 + 1.008
= 64.008 miles per hour < 65 miles per hour
If it less
Speed limit = 63 - (1.6% of 63)
= 63 -1.008
= 61.992 miles per hour < 65 miles per hour
Therefore, it is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.
The complete question is:
The reading on a car speedometer has 1.6% maximum error the speed limit on a road is listed 65 miles per hour.

one side of rectangle is 5cm than the other side. its perimeter is 38 cm. find the measure of the sides
The measure of the sides of rectangle is 14cm.
What is rectangle?Each pair of neighboring sides in a rectangle are perpendicular, making it a special case of a parallelogram. A parallelogram is a specific type of trapezium, also referred to as a trapezoid in North America, in which the lengths of the two pairs of opposite sides are parallel. A quadrilateral with four right angles is a rectangle. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equal sides.
Given that,
One side of rectangle is 5cm than the other side.
Its perimeter is 38 cm.
P = 2b +2 h
38= 2b+ 2(5)
38= 2b+ 10
38-10= 2b
28= 2b
b = 28/2
b= 14cm.
Therefore, the measure of the sides is 14cm.

29 less than -10 times a number is equal to -18 times the number plus 91
Answer:
-10x - 29 = -18x + 91
x = 15
Step-by-step explanation:
29 less than -10 times a number is equal to -18 times the number plus 91:
-10x - 29 = -18x + 91
add 21 to both sides:
-10x - 29 + 29 = -18x + 91 + 29
-10x = -18x + 120
add 18x to both sides:
-10x + 18x = -18x + 120 + 18x
8x = 120
divide both sides by 8:
8x/8 = 120/8
x = 15

The scale on a map is 1 : 30000
What is the actual distance represented by 1 centimetre?
When the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre is 300 meters.
How to calculate the distance?It should be noted that in order to get the distance, we have to convert 1cm to meter. It should be noted that;
100cm = 1 meter
1cm = 1/100 = 0.01 meters.
Therefore, when the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre will be:
= (0.01 × 300000)
= 300 meters.
Therefore, the distance is 300m
