Answer:
x = 10/9
Step-by-step explanation:
Solve:
27^(3x-2) = 81
When solving equations in exponential form make sure the two bases on both sides are the same.
3^3(3x-2) = 3^4
Once the two bases are the same you cancel them out and used its exponent to solve the equation.
3(3x-2) = 4
9x-6 = 4
Add 6 to both sides.
9x-6+6 = 4+6
9x = 10
Divide both sides by 9.
x = 10/9
Therefore x = 10/9.

Bob invested his savings in two investment funds. The amount he invested in Fund A was $8000 less than the amount he invested in Fund B. Fund A
returned a 2% profit and Fund B returned a 7% profit. How much did he invest in Fund B, if the total profit from the two funds together was $1730?
a = amount invested at 2%
how much is 2% of "a"? (2/100) * "a", namely 0.02a.
b = amount invested at 7%
how much is 7% of "b"? (7/100) * "b", namely 0.07b.
We know that fund A is less than fund B by 8000, that is a = b - 8000.
we also know that the yielded amount in interest is $1730, so if we simply add their interest, that'd be 0.02a + 0.07b = 1730.
[tex]\boxed{a = b - 8000} \\\\\\ 0.02a~~ + ~~0.07b~~ = ~~1730\implies 0.02(\stackrel{a}{b-8000})~~ + ~~0.07b~~ = ~~1730 \\\\\\ 0.02b-160+0.07b=1730\implies 0.02b+0.07b=1890\implies 0.09b=1890 \\\\\\ b=\cfrac{1890}{0.09}\implies \blacksquare~~ b=21000 ~~\blacksquare[/tex]

The distance between the two points are-9.87 units.
What is referred as the distance formula?In coordinate geometry, we have a list of distance formulas that can be used to obtain the distance between two points, the distance between a point and a line, the distances between two vertical lines, this same distance between these two parallel planes, and so on.The Euclidean distance formula is another name for the distance formula used to calculate the distance between 2 points in a two-dimensional plane. Acknowledge two points in the 2D plane, A(x₁, y₁) and B, to derive the formula (x₂, y₂). Assume 'd' represents the distance from A to B.The distance formula is;
d² = (y₂ - y₁)² + (x₂ - x₁)²
Let the two given points be;
A(x₁, y₁) = (-1,-9)
B(x₂, y₂) = (6, - 16)
Put the values in the formula;
d² = (-16 + 9)² + (6 + 1)²
d² = (-7)² + (7)²
d² =2 (7)²
d = 7√2
d = 7×1.41
d = 9.87
Therefore, the distance between the two points is found as 9.87 units.

An herbalist has 50 oz of herbs costing $4 per ounce. How many ounces of herbs costing $1 per ounce should be mixed with these 50 oz of herbs to produce a mixture costing $2.50 per ounce?
The ounces of herbs costing $1 per ounce that should be mixed with these 50 oz of herbs to produce a mixture costing $2.50 per ounce?
is 50 ounces.
How to illustrate the information?Let x = the amount of herb that costs $1 per ounce.
Based on the information,the total weight will be:
x + 50 = y.
At $2.50, the cost of the mixture will be:
1x + 4(50) = 2.50y
x + 200 = 2.50y
x + 200 = 2.50(x + 50)

length: 343 marea: 6418 m²Step-by-step explanation:
Given an oval track in the shape of a 48 m by 96 m rectangle with semicircular ends, you want the length of the track and the area enclosed.
Track LengthIf you remove the rectangle, you see that what remains is a circle of diameter 48. The length of that circular portion of the track is the circumference of the circle:
C = πd
C = π(48 m) = 48π m ≈ 151 m
Added to that length are the two 96 m sides of the rectangle. So, the total length of the track is ...
track length = curved length + straight length
track length = 151 m + 2×96 m = 343 m
The length of the track is 343 meters.
Enclosed areaThe area enclosed by the track includes the area of the circle we saw above, and the area of the rectangle.
The radius of the circular portion is half the diameter, or 24 m. Then the area is ...
A = πr²
A = π(24 m)² = 576π m² ≈ 1810 m²
The area of the rectangular portion is the product of length and width:
A = LW
A = (96 m)(48 m) = 4608 m²
The enclosed area is the sum of these areas:
enclosed area = area of circle + area of rectangle
enclosed area = 1810 m² +4608 m² = 6418 m²
The area enclosed by the track is 6418 square meters.
The length (perimeter) of the track is approximately equal to 342.796 meters and the area enclosed by the track is approximately equal to 6417.557 square meters.
What is the perimeter and the area enclosed by the track?In this problem we have a composite figure generated by a rectangle and two semicircles, of which we must determine its perimeter and area. The perimeter is the sum of the contour lengths of the semicircles and the rectangle and the enclosed area is the sum of areas of the two semicircles and a rectangle.
The perimeter of the composite figure is:
p = 2π · r + 2 · l
p = 2π · (24 m) + 2 · (96 m)
p ≈ 342.796 m
A = π · r² + l · (2 · r)
A = π · (24 m)² + (96 m) · (48 m)
A ≈ 6417.557 m²
The length (perimeter) of the track is approximately equal to 342.796 meters and the area enclosed by the track is approximately equal to 6417.557 square meters.

You have four cards: Jack, Queen, King, and Ace. What is the probability of drawing a face card, not replacing it, and then choosing another face card?
Write in fraction form!
Step-by-step explanation:
if I understand you correctly, then we have the 4 described cards. 3 of these 4 cards are face cards (Jack, Queen, King).
a probability is always desired cases over totally possible cases.
so, for the first pull we have a probability of
3/4 = 0.75
we have 4 total possibilities, and 3 of them are the desired outcome.
for the second pull we have then only 3 cards left (we did not replace the first pulled card). and because the first pulled card was in this scenario a face card, 2 out of these 3 cards are face cards.
so, the probability to pull a face card here is
2/3 = 0.66666...
when we combine these 2 events into one connected event (we are creating event 1 AND event 2), we multiply the probabilities, giving us
3/4 × 2/3 = 6/12 = 1/2 = 0.5

Two factory plants are making TV panels. Yesterday, Plant A produced 4 times as many panels as Plant B. Three percent of the panels from Plant A and 2% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 980 defective panels?
Answer:
7000 panels.
Step-by-step explanation:
Let x be the number of panels produced by Plant B.
Therefore:
4x = number of panels produced by Plant A.x = number of panels produced by Plant B.Given information:
Defective panels from Plant A = 3%Defective panels from Plant B = 2%Total number of defective panels = 980Create an equation with the given information and defined variables, remembering to write the percentages in their decimal form:
[tex]\implies 0.03(4x) + 0.02x = 980[/tex]
To find the number of panels Plant B produced, solve the found equation for x:
[tex]\implies 0.03(4x) + 0.02x = 980[/tex]
[tex]\implies 0.12x + 0.02x = 980[/tex]
[tex]\implies 0.14x = 980[/tex]
[tex]\implies \dfrac{0.14x}{0.14} = \dfrac{980}{0.14}[/tex]
[tex]\implies x=7000[/tex]
Therefore, Plant B produced 7000 panels.
Trey Invested his savings in two Investment funds. The $12,000 that he invested in Fund A returned a 1% profit. The amount that he invested in Fund B returned a 6% profit. How much did he invest in Fund B, if both funds together returned a 3% profit?
The amount Trey invested in Fund B is $8,000.
Profit is a residual income, It is the gain amount from any kind of business activity. In short, if the selling price (SP) of the product is more than the cost price (CP) of a product, then it is considered as a gain or profit. while return is a total revenue. Profits may be negative, whereas returns, such as wages and interest are always positive.
amount invested in Fund A = $12,000 (given)
profit returned by Fund A = 1% of $12,000 (given)
= 1/100*$12,000
= $120
Let amount invested in Fund B = x (assumption)
profit returned by Fund B = 6% of x (given)
= 6/100*x
= $ 6x/100
Given that both funds A and B together returned a 3% profit, So the equation we get is
120+6x/100 = 3% of (12,000+x)
(12,000+6x)/100 = 3/100* (12,000+x)
12,000+6x = 3(12,000+x)
12,000+6x = 36,000+3x
6x-3x = 36,000-12,000 (bringing like terms on same side)
3x = 24,000
x = 24,000/3
x = $8,000
Therefore, we can conclude that the amount Trey invested in Fund B is $8,000
