The miles previously covered by algae is 6 miles
let m represent the miles of the coastline covered by algae before the clean-up
fraction of miles covered after the clean-up = [tex]\frac{1}{3}[/tex] x m = [tex]\frac{1}{3}m[/tex]
miles covered after the clean-up = 2 miles
[tex]\frac{1}{3}m[/tex] = 2 miles
to determine the value of m, make m the subject of the formula.
To do this, take the following step :
multiply both sides of the equation by 2
m = 2 miles x 3
m = 6 miles

Which of the following equations could be solved to determine the length of QR?

B) QR2 = 202 + 272 - 2(20)(27)
C) cos 99 cos R
QR
20
D) QR2 = 202 + 272 - 2(20)(27) · cos 99°
Answer: D) QR^2 = 20^2 + 27^2 – 2(20)(27) ⋅ cos 99°
Step-by-step explanation:
since you have the lengths of two sides and their included angle, you can use the law of cosines to solve for the missing side. let a, b, and c be the side lengths, and A be side a's respective opposite angle:
the law of cosines states that
a^2 = b^2 + c^2 - 2bc ∙ cosA

If f(x) = ax + b represents a linear function, describe the a and b values that produce a constant function?
In f(x)=ax+b, 'a' is the slope and b is the initial value or y intercept
Given :
Given function is f(x)=ax+b
f(x)=ax+b is the linear equation
The graph of a linear equation is a line. The value of 'a' tell us the steepness of the line that is the slope of the line .
'b' is the initial value . when x=0, f(x)=a(0)+b
that is f(0)=b
So, 'b' is the initial value or y intercept.

Given that f(x)=2x-8, determine the average rate of change over the interval [2, 8].
Answer:
2
Step-by-step explanation:
The average rate of change over [2, 8] is the change in the y-values over the change in the x-values.
[tex]\frac{f(8) - f(2)}{8 - 2}[/tex]
[tex]f(8) = 2(8) - 8 = 16 - 8 = 8[/tex]
[tex]f(2) = 2(2) - 8 = 4 - 8 = -4[/tex]

4. Find the equation of the lines described.
A. Find the equation of the line parallel to y = 3x -5
and passing through
(-4, 7).
Answer:
y = 3x + 19
Step-by-step explanation:
Apply point-slope form. Our point (y1, y2) is (-4, 7) and our slope (m) is 3. The slope of y = 3x - 5 is 3 because it is "m" in y = mx + b. Parallel lines have the same slope.
y - y1 = m(x-x1)
y - 7 = 3(x-(-4))
y - 7 = 3(x+4)
y - 7 = 3x + 12
y = 3x + 19

Step-by-step explanation:
5/14 to the son.
that leaves 9/14 of the total.
these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.
how do we do that ?
well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).
but in general by multiplying. so 2/3 of 8/14 is
9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14
and then little surprising 1/3 is
9/14 × 1/3 = 9 / 14×3 = 3/14
now, we know, these 3/14 are 36000.
what we need to know is how much is 14/14 or 1/1 : the whole amount.
well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).
it in total, multiply it with the reverse fraction : 14/3
36000 × 14/3 = 12000×14 = 168000
Calculate the volume of a warehouse that has inside dimensions of 22.4 meters by 11.3 meters by 5.2 meters.
The volume of the warehouse with the three dimensions is V = 1,316.224 cubic meters.
Given data:
To calculate the volume of the warehouse, you need to multiply its length, width, and height:
Volume = Length * Width * Height
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Given the dimensions:
Length = 22.4 meters
Width = 11.3 meters
Height = 5.2 meters
Substitute these values into the formula:
Volume = 22.4 m × 11.3 m × 5.2 m
Calculate the result:
Volume = 1,316.224 m³
So, the volume of the warehouse is approximately 1,316.224 cubic meters.

Gordon makes 4/5 of a recipe with 2/3 bag of cheese. At this rate, what fraction of the bag of cheese will Gordon use to make the entire recipe?
Answer:
Gordon will use 5/6 of the bag of cheese to make the entire recipe.
Step-by-step explanation:
We are given that Gordon makes 4/5 of a recipe with 2/3 bag of cheese.
And we want to determine what fraction of the bag of cheese Gordon will use to make the entire recipe.
We can write the following ratio:
[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}[/tex]
Find the unit rate. Multiply both layers by 5/4:
[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}\times \frac{\dfrac{5}{4}}{\dfrac{5}{4}}[/tex]
Multiply:
[tex]\displaystyle \frac{\dfrac{5}{6}\text{ bag of cheese}}{1 \text{ recipe}}[/tex]
In conclusion, Gordon will use 5/6 of the bag of cheese to make the entire recipe.

A man sold a calculator at a loss of 12℅. If selling price was Rs.7040, what was the cost price?
Answer:
Rs.6195.20
Step-by-step explanation:
So first you need to find 12 % of Rs.7040. Thus:
[tex]\frac{12}{100}[/tex] × 7040 = 844.80
Then you subtract 844.80 from 7040 from which you get Rs.6195.20
Rs.6195.20 was the cost price.

Two-thirds a numberx plus 4 is 8.
Answer:
n = 6
Step-by-step explanation:
To solve this you can use an equation such as:
[tex]\frac{2}{3} n+4=8\\\\[/tex]
We need to so for n. Subtract 4 from both sides to get the variable (n) alone. 4 - 4 and 8 - 4 equals:
[tex]\frac{2}{3}n=4[/tex]
So now we divide both sides by 2/3.
This now equals:

Junaid has a rectangular box open from the top as in the figure. He paints base and 4 lateral faces as shown. He paints only up to th of the height of the box to save paint. Find the total surface area he painted.
The surface area is the total area occupied by the object. The surface area of the painted figure is [tex]440m^2.[/tex]
From the attached box, we have the following:
[tex]L = 20m[/tex] -- length
[tex]W = 10m[/tex] --- width
[tex]H = \frac 45 \times 5m = 4m[/tex] --- the painted height
Since the box has an open-top, the surface area is:
[tex]Area = LW + 2(WH + LH)[/tex]
So, we have:
[tex]Area = 20 \times 10 + 2 \times (10 \times 4 + 20 \times 4)[/tex]
[tex]Area = 200 + 2 \times (120)[/tex]
[tex]Area = 200 + 240[/tex]
[tex]Area = 440[/tex]
Hence, the painted area is [tex]440m^2.[/tex]
