8 million tonnes of fish were caught in the North sea in 2005, if the catch is reduced by 20% each year for four years, what amount can be caught at the end of this time
Answer:
At the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.
Step-by-step explanation:
Given that 8 million tonnes of fish were caught in the North sea in 2005, if the catch is reduced by 20% each year for four years, to determine what amount can be caught at the end of this time the following calculation must be performed :
100 - 20 = 80
Year 0 = 8 million
Year 1 = 8 x 0.8 = 6.4 million
Year 2 = 6.4 x 0.8 = 5.12 million
Year 3 = 5.12 x 0.8 = 4,096 million
Year 4 = 4.096 x 0.8 = 3.2768 million
Thus, at the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.
What is it’s equation in point slope form?
Answer:
y = -2x + 28
Step-by-step explanation:
Slope intercept form is-
y = mx + b
y = y coordinate
m = slope, the rise/run
x = x coordinate
b = the y-intercept, the place the line crosses the y-axis.
Now, fill in the formula with the proper information.
y = -2x + b You can use the point (10, 8) for the x and y coordinates to find b
8 = -2(10) + b Now solve for b
8 = -20 + b
+20 +20
28 = b Now substitute 28 in for b
y = -2x + 28
Answer:
y-8=-2(x-10)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=-2(x-10)
Can you solve it please and explain step by step how u got it ?????Please
Answer:
m<7 = 61
Step-by-step explanation:
These angles (<7, and <8) are adjacent to each other (they are next to each other), therefore they are supplementary (add up to 180).
180 - 119 = m<7

What is the area of the triangle?
9514 1404 393
Answer:
7 square units
Step-by-step explanation:
There are several ways the area of triangle EBD can be found.
find the lengths EB, BD, DE and use Heron's formula (messy due to roots of roots being involved).define point G at the lower left corner and subtract the areas of ∆DEG and BCD from trapezoid BCGE.figure the area from the coordinates of the vertices.use Pick's theorem and count the dots.We choose the latter.
__
Pick's theorem says the area of a polygon can be found as ...
A = i + b/2 -1
where i is the number of grid intersection points interior to the polygon, b is the number of grid points intersected by the border.
The attached figure shows the lines EB, BD, and DE intersect one point in addition to the vertices. So, b=4. A count of the red dots reveals 6 interior points (i=6). So, the area is ...
A = 6 + (4/2) -1 = 7
The area of ∆EBD is 7 square units.

Consider the expressions show below, please help me!
Answer:
(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5
(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7
Step-by-step explanation:
✔️(3x² - 6x + 11) - (10x² - 4x + 6)
Open the bracket by applying the distributive property
3x² - 6x + 11 - 10x² + 4x - 6
Add like terms
-7x² - 2x + 5
Therefore:
(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5
✔️(-3x² - 5x - 3) - (-10x² - 7x + 2)
Apply distributive property
-3x² - 5x - 3 + 10x² + 7x - 2
Add like terms
7x² + 2x - 5
Therefore:
(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
✔️(12x² + 6x - 5) - (5x² + 8x - 12)
12x² + 6x - 5 - 5x² - 8x + 12
Add like terms
7x² - 2x + 7
Therefore:
(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7

Step-by-step explanation:
50 apples cost $25. How much would 75 apples cost?
Answer:
37.5
Step-by-step explanation:
If 50 apples cost 25 then all you need to do is 25 x 1.5 = 37.5
And we know this is correct because 25 divided by 2 is 12.5.
so 12.5 is how much for 25 apples and if you multiply 25 times 3 it is equal to 75 so you need to mutliply 12.5 times 3.
12.5 x 3 = 37.5

Step-by-step explanation:
For this triangle, since the angle is included between 2 given sides, the formula will be:
[tex]A =\frac{1}{2}ab*ac*sin(angleA)[/tex]
Putting values where they belong:
[tex]A=\frac{1}{2}(10)(12)sin72[/tex]
Do all that in your calculator (in degree mode, NOT radian!) to get
A = 57.1 square cm

Answer:
x = 1
y = -1
Step-by-step explanation:
-5x + 5y = -10
rewrite the order:
5y = 5x - 10
6x + 5y = 1
rewrite the order:
5y = 1 - 6x
substitute for 5y:
5x - 10 = 1 - 6x
simplify:
11x = 11
x = 1
5y = 1 - 6(1) = -5
y = -1
