ps. use Pythagoras to help you.
Answer:
\(c=15\)
Step-by-step explanation:
You can use Pythagoras theorem to find the value of c
Formula to find the hypotenuse:
\(c=\sqrt{a^{2}+b^{2} }\)
The value of a in the formula will be the height & the value for b in the formula is the base.
Now, add the values in the formula:
\(c=\sqrt{9^{2}+12^{2} }\)
\(c=\sqrt{81+144 }\)
\(c=\sqrt{225}\)
\(c=15.96871942\)
You can simply say that:
\(c=15\)

1.Solve for y. y = 5/6x + 10
Answers
To solve for y, you can start by isolating y on one side of the equation by moving all the terms that do not contain y to the right-hand side of the equation.
In this case, you can do this by subtracting 10 from both sides of the equation:
y - 10 = 5/6x + 10 - 10
This simplifies to:
y - 10 = 5/6x
Then, you can add 10 to both sides of the equation to get:
y = 10 + 5/6x
So, the solution for y is y = 10 + 5/6x.

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
Answers
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)
When evaluated, we have
x = 0.833

What is the area of this trapezoid?
Enter your answer in the box.
Answers
Answer:
153 units squared
Step-by-step explanation:
first, multiply 10 x9 to find the area of the rectangle, which is 90
then find the area of the triangle. The formula for area of a triangle is
A=1/2bh
so, 7 x 9= 63 divided by 2 is 31.5
since there are 2, multiply 31.5 x 2= 63
add 63 to 90 which is 153
Answer: 153 sq. units
Step-by-step explanation:
Base a = 10
Base b = 7x2 = 24
Height = 9
area of trapezoid = 1/2 * (a+b) * h
= 10+24 * 9 /2
= 306/2 = 153

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish

What is the approximate area of shadad region? use 3.14 π
A. 16.86
B. 19
C.18.43
D.23.14
Answers
Step-by-Step Explanation:
Area of Shaded Area will be the Area of the Rectangle (Total Area) minus the Area of the Circle.
Finding Area of Circle :-
Radius (r) = 1 in
Area = πr^2
Therefore,
= πr^2
= π * r * r
= 3.14 * 1 * 1
=> 3.14
Area = 3.14 in^2
Finding Area of Rectangle (Total Area) :-
Length (l) = 5 in
Breadth (b) = 4 in
Area = l * b
Therefore,
= l * b
= 5 * 4
=> 20
Area = 20 in^2
Finding Area of Shaded Region :-
Area of Rectangle - Area of Circle
Therefore,
= 20 - 3.14
= 16.86
Area = 16.86 in^2

5in • 4in - (1 squared • 3.14)

The slope of a line can be calculated using the formula:
slope = (change in y-coordinates)/(change in x-coordinates)
In this case, the change in x-coordinates is (x + 9) - (3 - 2x), which simplifies to 4x + 6.
The change in y-coordinates is 7 - 12, which is -5.
For a vertical line, the slope is undefined, which means the change in x-coordinates must be zero. Therefore, we set 4x + 6 = 0 and solve for x:
4x + 6 = 0
4x = -6
x = -6/4
x = -3/2
So, the value of x for which the line passing through points F(3-2x, 12) and G(x + 9, 7) is vertical is x = -3/2.

Answer:
\(\huge\boxed{\sf x =28 \textdegree}\)
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°\(\rule[225]{225}{2}\)
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees
