A garden table and a bench cot $572 combined. The garden table cot $78 le than the bench. What i the cot of the bench?
The cost of the bench is $325 and the cost of the garden table is $247.
The situation given in the question can be solved by using equation, with two unknown variables, x is the cost of the garden table and y is teh cost of the bench. Considering the garden table is $78 less than the bench. We get the equation for the value of x, then we substitute it in sum equation 1 to get the value of bench.
x+y=$572 ----------------(1)
x=y-$78 ---------------(2)
Substitute equation 2 in 1, we get.
y-$78+y=$572
2y-$78=$572
2y=$572+$78
2y=$650
y=650/2
y=$325
We got the cost of the bench, we substitute this value in equation 2, to get the value of garden table.
x=y-$78
x=$325-$78
x=$247
Hence, the cost of the bench is $325 and garden table is $247.

What is a linear function?The slope-intercept representation of a linear function is given as follows:
y = mx + b
The coefficients of the function and their meaning are listed as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x increases by one.b is the y-intercept of the function, which is the value of the function when it's graph crosses the y-axis.From the graph and from the options, the function crosses the y-axis at y = 11/3, hence the intercept is given as follows:
b = 11/3.
When x increases by 5, from 0 to 5, the function decays from 11/3 to 2, hence the slope is obtained as follows:
m = (2 - 11/3)/5 = (6/3 - 11/3) x 1/5 = -5/3 x 1/5 = -1/3.

As per the question statement, a mixed fraction, 6(3/4) is divided by another fraction 1(2/3),
And we are required to calculate the quotient of the above mentioned division.
To solve this question, we will first convert the mixed fractions, into improper fractions, and then use the reciprocal rule to obtain our desired answer, that is,
[{6(3/4)}/1(2/3)]
= [{(4 * 6) + 3}/4]/[{(3 * 1) + 2}/3]

Answer:
The perimeter of [tex]\triangle[/tex][tex]PQR[/tex] is [tex]16[/tex] feet
Step-by-step explanation:
The perimeter of [tex]\triangle PQR[/tex] can be calculated as follows
Since [tex]\overline{PQ} \cong \overline{PR}[/tex] , then the length of [tex]PQ[/tex] is equal to the length of [tex]PR[/tex]
[tex]PQ = PR = 5~\text{feet}[/tex]
Since the angle [tex]\angle PSR[/tex] is [tex]90^{\circ}[/tex], then [tex]\triangle PSR[/tex] is a right triangle
Since [tex]\triangle PSR[/tex] is a right triangle, then the length of [tex]RS[/tex] can be calculated by the Pythagorean theorem as follows
[tex]c^{2}=a^{2}+b^{2}[/tex]
Where [tex]c[/tex] is the hypotenuse or the side [tex]PR[/tex], [tex]a[/tex] is the side [tex]RS[/tex], and [tex]b[/tex] is the side [tex]PS[/tex]
Substitute [tex]5[/tex] for [tex]PR[/tex], [tex]4[/tex] for [tex]PS[/tex] into the Pythagorean theorem
[tex]5^{2}=a^{2}+4^{2}[/tex]
Simplify the equation
[tex]25=a^{2}+16[/tex]
Move [tex]16[/tex] from the right side to the left side and change its sign to negative
[tex]25-16=a^{2}[/tex]
Simplify the equation
[tex]9 = a^{2}[/tex]
Find the value of [tex]a[/tex] by taking square root of both sides of the equation
[tex]\sqrt{9}=\sqrt{a^{2}}[/tex]
[tex]3 = a[/tex]
As a matter of fact the square root of [tex]9[/tex] are [tex]3[/tex] and [tex]-3[/tex], but disregard the negative value since the length value is never negative
Since the value of [tex]a[/tex] is [tex]3[/tex], then the length of [tex]RS[/tex] is [tex]3[/tex] feet
Since the angle [tex]\angle PSR[/tex] is [tex]90^{\circ}[/tex], then angle [tex]\angle PSQ[/tex] is also [tex]90^{\circ}[/tex] or
[tex]\angle PSQ = \text{straight angle}-90^{\circ}[/tex]
[tex]\angle PSQ = 180^{\circ}-90^{\circ}=90^{\circ}[/tex]
Since [tex]\overline{PQ} \cong \overline{PR}[/tex] and [tex]\angle PSQ = \angle PSR[/tex], then [tex]\triangle PSR \cong \triangle PSQ[/tex]
Since [tex]\triangle PSR \cong \triangle PSQ[/tex], then the length of [tex]RS[/tex] is equal to the length of [tex]QS[/tex]
[tex]RS=QS=3~\text{feet}[/tex]
The perimeter of [tex]\triangle PQR[/tex] is the sum of the length of the following sides
[tex]\text{the perimeter of} ~\triangle PQR= PQ+QS+RS+PR[/tex]
Substitute [tex]5[/tex] for [tex]PQ[/tex], [tex]3[/tex] for [tex]QS[/tex], [tex]3[/tex] for [tex]RS[/tex], [tex]5[/tex] for [tex]PR[/tex] in the expression of the perimeter
[tex]\text{the perimeter of} ~\triangle PQR= 5+3+3+5[/tex]
Simplify the equation
[tex]\text{the perimeter of} ~\triangle PQR=16~\text{feet}[/tex]
Hence the perimeter of [tex]\triangle{PQR}[/tex] is [tex]16~\text{feet}[/tex]

What is Markup?
The term "markup" describes the discrepancy between a product's selling price and its actual cost. It is specified as a percentage over the price. In other words, the seller makes a profit when the price of the commodity.
A unit's gross profit, which is the sales price less the cost to create or buy it for resale, is divided by its cost to determine the markup %. The markup percentage is computed as (12 - 8) / 8 and is equal to 50% if an item costs the business $8 to produce but is sold for $12.
Markup percentage=[(selling price - unit cost)/unit cost]*100
Markup percentage= [(900-400)/400]*100=1.25*100

The value of [m] will be 2.
What is mean, median and mode?The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.Given is the median of the ordered set of observations 2, 3, (4m-3), (3m + 1), 11 and 13 in ascending order is 6.
We have the following data as -
2, 3, (4m-3), (3m + 1), 11, 13
N = 6
So median will be -
{(4m - 3) + (3m + 1)}/2 = 6
(4m - 3) + (3m + 1) = 12
4m + 3m - 3 + 1 = 12
