Given:
The inequality is
[tex]x-(5-3x)\leq 2x-1[/tex]
To find:
The solution of the given inequality.
Solution:
We have,
[tex]x-(5-3x)\leq 2x-1[/tex]
[tex]x-5+3x\leq 2x-1[/tex]
[tex]4x-5\leq 2x-1[/tex]
Subtract 2x from both sides.
[tex]4x-5-2x\leq 2x-1-2x[/tex]
[tex]2x-5\leq -1[/tex]
Add 5 on both sides.
[tex]2x-5+5\leq -1+5[/tex]
[tex]2x\leq 4[/tex]
Divide both sides by 2.
[tex]x\leq 2[/tex]
It means, the numbers less than 2 or 2 are included in the solution set.

The value of y varies directly with x and y= 125 when x = 25. what is the value of y when x=2?
Answer:
Y = 10
Step-by-step explanation:
As, Y / X = 125/25
125/25 = 5
Therefore, y = 5x
So when x = 2
Y = 5x
So, Y = 5x2
Therefore, Y = 10
[y] will be equivalent to 10, if [x] is equal to 2
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
y = mx also represents direct proportionality. We can write [m] as -
m = y/x
OR
y₁/x₁ = y₂/x₂
Given is the value of [y] varies directly with [x] and y = 125 when x = 25.
Using the formula for direct proportionality -
y₁/x₁ = y₂/x₂
125/25 = y₂/2
y₂ = (125 x 2)/25
y₂ = 5 x 2
y₂ = 10
Therefore, [y] will be equivalent to 10, if [x] is equal to 2

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has a length 1/2in and 1/6in. The actual tiles have length 2/3ft and 2/9ft. What is the ratio of the length of a tile in the model to the length of actual tile? What is the ratio of the area of tile in the model to the area of an actual tile?
Answer:
Ratio of the lengths = 1 : 16 and 1 : 15.71
Ratio of the Area = 1 : 251.29
Step-by-step explanation:
Model = 1/2in and 1/6in.
Actual = 2/3ft and 2/9ft.
1 ft = 12 inches
2/3 ft = 8 inches
2/9 ft = 2.67 inches
Model = 0.5 inches and 0.17 inches
Actual = 8 inches and 2.67 inches
Ratio
0.5 : 8 and 0.17 : 2.67
= 0.5 / 8 and 0.17 / 2.67
= 1 / 16 and 1 / 15.71
= 1 : 16 and 1 : 15.71
Area of the tile in the model = length × width
= (0.5 × 0.17) inches
= 0.085 inches
Area of the actual tile = length × width
= (8 × 2.67) inches
= 21.36 inches
Ratio of the area
0.085 : 21.36
= 0.085 / 21.36
= 1 : 251.29

The price of an item has risen to 297 today. Yesterday it was 110 . Find the percentage increase.
Answer:
170
Step-by-step explanation:
original value = 110
final value = 297
the increase is the difference between both values
increase = final value - original value = 297 - 110 = 187
percentage increase = (increase/original value)*100
= (187/110)*100
=170

The width of the rectangle is equal to the greatest common monomial factor of 6n^4, 20n^3,6n 4 ,20n 3 ,6, n, start superscript, 4, end superscript, comma, 20, n, cubed, comma and 14n^214n 2 14, n, squared. What is the length and width of the rectangle?
Given:
Area of rectangle = [tex]6n^4+20n^3+14n^2[/tex]
Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex].
To find:
Length and width of the rectangle.
Solution:
Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex] is
[tex]6n^4=2\times 3\times n\times n\times n\times n[/tex]
[tex]20n^3=2\times 2\times 5\times n\times n\times n[/tex]
[tex]14n^2=2\times 7\times n\times n[/tex]
Now,
[tex]GCF(6n^4, 20n^3,14n^2)=2\times n\times n=2n^2[/tex]
So, width of the rectangle is [tex]2n^2[/tex].
Area of rectangle is
[tex]Area=6n^4+20n^3+14n^2[/tex]
Taking out GCF, we get
[tex]Area=2n^2(3n^2+10n+7)[/tex]
We know that, area of a rectangle is the product of its length and width.
Since, width of the rectangle is [tex]2n^2[/tex], therefore length of the rectangle is [tex](3n^2+10n+7)[/tex].
Lisa was throwing a dart at a target. She threw 50 times with her left hand and 50 times with her right hand. The histograms show the distance Lisa missed the target by each time. Make an inference about which hand Lisa has better aim with based on the median of each data set. Justify your response.
Answer:
The answer is "More accurately is the left hand".
Step-by-step explanation:
In the given-question when we look at the given equation and see its given graph. This graph offers a much more reliable right hand because it has a smaller distance than that of the left. That being said, the left hand never surpassed the target, again and again, that's why the above given choice is correct.
Arianna is packing scented candles and candle holders into gift boxes. She has 84 candles and 48 holders, and each box must contain both items. She puts the same number of candles in each box, and the same number of holders in each box. What is the maximum number of gift boxes Arianna can pack, and how many scented candles and candle holders will each box have?
Answer:
Step-by-step explanation:
If she has 84 candles and 48 holders, we can write out the factors of both values as shown
For candles
84 = 2×2×3×7
84 = 12×7
For 48
48 = 2×2×2×2×3
48 = (2×2)×(2×2×3)
48 = 4×12
48 = 12×4
From both factors, we can are that 12 common to both of them. This means that the maximum number of gift boxes Ariana can pack is 12
The other factors will give the amount of scented candles and candle holders that each box will have. This means that each box will have 7scented candles and 4 holders.

C) A restaurant operator in Accra has found out that during the partial lockdown, if she sells a plate of her food for GH¢20 each, she can sell 300 plates, but for each GH¢5 she raises the price, 10 less plates are sold. What price in GH¢ should she sell the plates to maximize her revenue?
Answer:
Maximum price = GH¢85
Step-by-step explanation:
Let p be the number of times she raises the price as well as the number of times 10 less plates are sold
Revenue, R = number of plates sold * price sold
R = (300 - 10p)(20 + 5p)
R = 6000 + 1500p - 200p - 50p²
R = 6000 + 1300p - 50p²
50p² - 1300p - 6000 = 0
p² - 26p - 120 = 0
finding the axis of symmetry, p = -b/2a
p = -(-26)/2*1
p = 13
Maximum price = 13 * 5 + 20 = GH¢85
Number of plates sold = 300 - 10 * 13 = 170 plates
Maximum revenue = GH¢85 * 170 = GH¢14,450
Lili has saved $2,500 money from her part time job at a bakery. Since she will not need this money for a few years, she decides to put the money in a 3-year CD (Certificate of Deposit) at a local credit union. The credit union offers Lili 2.75% APR, compounded quarterly. How much will Lili's CD be worth at the end of the 3 years?
Answer:
Lili's CD be worth at the end of 3 years is $2714.23

-7=-17
-7=14
The equation for the line perpendicular to the line represented by the equation [tex]y= \ \frac{1}{3} x-2[/tex] that passes through the point [tex](4,-7)[/tex] will be [tex]y=-3x+5[/tex].
What is equation for the perpendicular line ?Equation for the perpendicular line, the perpendicular lines have opposite-reciprocal slopes.
Now,
The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
Equation of a perpendicular line [tex]y=mx-b[/tex]
Here, [tex]m=[/tex] slope
So,
We have
[tex]y= \ \frac{1}{3} x-2[/tex]
Here,
[tex]m = \frac{1}{3}[/tex]
As mentioned above, we have to find the slope of perpendicular,
i.e.
(slope of perpendicular) [tex]m[/tex] [tex]=-3[/tex]
So,
[tex]y=mx-2[/tex]
[tex]y=(-3)x-b[/tex]
We have
Point [tex](4,-7)[/tex] through which line passes. i.e.
[tex]x=4[/tex]
[tex]y=(-7)[/tex]
Therefore,
[tex]-7=(-3)*4-b[/tex]
⇒ [tex]b=7-12[/tex]
[tex]b=(-5)[/tex]
So, Equation of a perpendicular line,
[tex]y=-3x+5[/tex]
So, Equation of a perpendicular line, [tex]y=-3x+5[/tex] which is derived from [tex]y=mx-b[/tex] .
Hence, we can say that the equation for the line perpendicular to the line represented by the equation [tex]y= \ \frac{1}{3} x-2[/tex] that passes through the point [tex](4,-7)[/tex] will be [tex]y=-3x+5[/tex].

6.045×10^40 ergs1.8×10^-2 mmStep-by-step explanation:
A) Your scientific or graphing calculator can tell you the product:
(3.9×10^33 erg/s)(1.55×10^7 s) = 6.045×10^40 ergs
__
B) 10^2 mm is 100 mm, about 4 inches, so 1.8×10^2 mm is about 7 inches. This is somewhat larger than the diameter of a human hair (and about the same size as the diameter of a human head).
1.8×10^-2 mm = 18 μm is a more reasonable estimate of hair diameter
(The range of hair diameters is reportedly about 17 to 181 μm, so the given dimension is on the low end.)
