Step-by-step explanation:
l = length
w = width = 15 ft
l = 2×w + 4 = 2×15 + 4 = 30 + 4 = 34 ft
the area of a rectangle is
area = l × w = 34×15 = 510 ft²
2x+7y=3 and x=-4y with substitution ?
Answer:
x=12
y=-3
Step-by-step explanation:
Because we already know what the value of x, we can use that value, -4y, to substitute it into the equation 2x+7y=3.
2(-4y)+7y=3 Simplify.
-8y+7y=3
-y=3 Divide both sides by -1 (to make y positive).
y=-3
Now, we can substitute y into the other equation, x=-4y.
x=-4(-3) Simplify.
x=12

what is the purpose of a statistical control chart?
The statistical control chart is discussed below.
What is statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.Given is the statistical control chart.
The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.Parts of a control chart -Points representing a statistic (e.g., a mean, range, proportion) of measurements of a quality characteristic in samples taken from the process at different times (i.e., the data)The mean of this statistic using all the samples is calculated (e.g., the mean of the means, mean of the ranges, mean of the proportions) - or for a reference period against which change can be assessed. Similarly a median can be used instead.A centre line is drawn at the value of the mean or median of the statisticUpper control and lower control limits (sometimes called "natural process limits") that indicate the threshold at which the process output is considered statistically 'unlikely' and are drawn typically at 3 standard deviations from the center line.Therefore, the statistical control chart is discussed above.

Maria wants to buy a pair of shoes for $22.50 and a shirt for $13.50. If the sales tax rate is 8.25%, what will be the amount of sales tax on Maria’s purchase?
Answer:
$2.97
Step-by-step explanation:
- add together the prices of the items; 22.50 + 13.50 = 36
- multiply the total by the tax; 36 x 8.25% or 36 x 0.0825 = 2.97
- The total sales tax is $2.97

How many zeros will be in the product of 5 x 105 = ________? Explain how you know.
Answer:
The is zero 0's in the answer. The way I know is that I put it into an equation, and started solving. I started off by multiplying 5x5=25. Next I noticed the next number I multiply 5 by is 0, so the next value will be 2 because the 2 from 25 was carried over. Finally I multiplied 100x5=500. And 500+25=520.

Determine which steps are used to find the product shown. Put the steps in the order in which they would be performed.
Factorization of the given polynomial to find the product is as follows;
Factorizing;

[tex]\dfrac{x^2 + 3*x +2}{x^2+ 6*x + 5} \times \dfrac{x^2 + 7*x +10}{x^2+ 4*x + 4} = \dfrac{(x + 2) * (x + 5)}{(x + 2)*(x + 2)} \times \dfrac{(x + 1) * (x + 2)}{(x + 1)*(x + 5)}[/tex]
The steps arranged in the order in which they would be performed are;

what is the answer to 8s-11s+6
Answer:
-3s + 6
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of the same variables. In this case:
8s - 11s + 6
(8s - 11s) + 6
-3s + 6
-3s + 6 is your answer.
~
Answer:
-3s + 6
Step-by-step explanation:
In order to find the answer you need to combine like terms. When you combine like terms you need to combine integers that have the same variable in this case 8 and 11 need to be combined due to the fact they both have the variable s.
8s - 11s + 6
(8s - 11s)
(8s - 11s) + 6
8s + -11s = -3s
= -3s + 6

Find the value of x when 6−3x = 5x-10x+12
Question is the image :
Answer:
x can be any real number except -5 and 7
Step-by-step explanation:
x is in the denominator and denominator cannot be 0
so 6 - |x-1| cannot be 0
==> |x-1| cannot be 6
because it's absolute value, so
x-1 cannot be 6 & x-1 cannot be -6
which give us the answer x cannot be 7 and x cannot be -5
so the answer is x can be any real number except -5 and 7
