Answer:
Length of the garden: 95 m
Width of the window: 86 cm
Step-by-step explanation:
Part A:
We can use the equation for area to find the length of the garden.
[tex]Area = Width * Length[/tex]
If we simply divide both sides of the equation by width, we will be solving for lenght:
[tex]\frac{Area}{Width} = Length[/tex]
Now, plug in the known values for the area and width of the garden:
[tex]\frac{6460}{68}=Length[/tex]
[tex]95=Length[/tex]
Part B:
This time, we'll have to use the equation for perimeter:
[tex]Perimeter = [2(Width)]+[2(Length)][/tex]
Because we want to know the width, and already know the perimeter and length we can once again use algebra to solve for the width:
[tex]Perimeter-[2(Length)] = 2(Width)\\\frac{Perimeter-[2(Length)]}{2} =Width[/tex]
Now, simply plug in the values for the perimeter and the length and solve:
[tex]\frac{370-[2(99)]}{2} =Width\\\\\frac{370-198}{2} =Width\\\\\frac{172}{2}=Width\\\\86=Width[/tex]
Therefore, the width of the window is 86 cm.

Tell whether the angles are complementary or supplementary. Then find the value of x.
Answer:
The angles are supplementary. X = 31
Step-by-step explanation:
The angles sum to equal 180 degrees, menaing they are supplementary. Add the degrees of each side 3x + 25 + 2x = 180 and solve for x. X should equal 31.
Assume the density of air = 1.2 kg/m3 and Cp = 0.3. Remember that Area= r2 where r is the blade length.
1)How many Watts can a turbine generate in a 10 m/s wind and 1m blade length?
2)How many Watts can a turbine generate in a 15 m/s wind and 0.50m blade length?
3)How many Watts can a turbine generate in a 20 m/s wind and 0.25m blade length?
HELP ASAP
The number of watts which is the power of the turbine for each case is respectively; 600 W; 506.25 W; 300 W
What is the power of the turbine?
We are given;
Density of air; ρ = 1.2 kg/m³
Area; A = r² with r being the blade length
Formula for power in turbine is;
P = ¹/₂ρAv³
1) v = 10 m/s and r = 1 m.
Thus;
P = ¹/₂ * 1.2 * 1² * 10³
P = 600 W
2) v = 15 m/s and r = 0.5 m.
Thus;
Power = ¹/₂ * 1.2 * 0.5² * 15³
P = 506.25 W
3) v = 20 m/s and r = 0.25 m.
Thus;
Power = ¹/₂ * 1.2 * 0.25² * 20³
P = 300 W

A board game uses the deck of 20 cards
shown to the right. Two cards are selected at
random from this deck. Calculate the
probability that both cards selected have a
1, both with and without replacement.
Using the probability concept, it is found that they are given by:
0.0316 = 3.16%, without replacement.0.04 = 4%, with replacement.What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Without replacement, there are 4 out of 20, and then 3 out of 19 cards with a 1, hence:
[tex]p = \frac{4}{20} \times \frac{3}{19} = 0.0316[/tex]
0.0316 = 3.16% probability that both cards selected have a 1 without replacement.
With replacement, in each trial, 4 out of 20, hence:
[tex]p = \frac{4}{20} \times \frac{4}{20} = 0.04[/tex]
0.04 = 4% probability that both cards selected have a 1 with replacement.

Frank discussed how people saw her in her final journal post, calling herself "a tangle of paradoxes." "As I've told you many times, I'm torn in two," she wrote. One half of myself is full of excitement, exuberance, flippancy, and, most importantly, the capacity to see the lighter side of things.

Give the equation of the line which is perpendicular to y = 5x + 6 and goes through the point (- 15, 2)
Answer:
x+5y+5=0
Step-by-step explanation:
y=5x+6
Therefore the gradient of the line = 5
Now reciprocate the gradient and negate it
i.e -1/5
let (x,y) and (-15,2) be points on the line
y-2/x-(-15)=-⅕
5y-10=-x-15
5y-10+15+x=0
x+5y+5=0
Therefore the equation of the line =
x+5y+5=0

The area of a square I 41 square units. Two of its vertices are located at (0,-3) and (4,2). Select the point that could be a third vertex of this square.
A. (0,7)
B. (-5,1)
C.(5,13)
D.(-2,-2)
E.(4,-6)
There may be more than one answer by the way .
The vertices of the square are the coordinates of the endpoints
The third vertex of the square could be (0,7) or (-5,1)
How to determine the third vertexTwo vertices of the square are:
(0,-3) and (4,2)
Calculate the distance between these vertices using:
[tex]d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]
Square both sides
[tex]d^2 = (x_2 - x_1)^2+(y_2 - y_1)^2[/tex]
The above expression represents the area of the square.
So, we have:
[tex](x_2 - x_1)^2+(y_2 - y_1)^2 = 41[/tex]
Next, we test the options with the given vertices (0,-3) and (4,2)
So, we have:
A. (0,7)
[tex](0 - 0)^2+(7 + 3)^2 = 41[/tex]
[tex]100 \ne 41[/tex]
[tex](0 - 4)^2+(7 - 2)^2 = 41[/tex]
[tex]41 = 41[/tex]
B. (-5,1)
[tex](-5 - 0)^2+(1 + 3)^2 = 41[/tex]
[tex]41 = 41[/tex]
[tex](-5 - 4)^2+(1 -2)^2 = 41[/tex]
[tex]82 \ne 41[/tex]
C.(5,13)
[tex](5 - 0)^2+(13 + 3)^2 = 41[/tex]
[tex]281 \ne 41[/tex]
[tex](5 - 4)^2+(13 -2)^2 = 41[/tex]
[tex]122 \ne 41[/tex]
D.(-2,-2)
[tex](-2 - 0)^2+(-2 + 3)^2 = 41[/tex]
[tex]5 \ne 41[/tex]
[tex](-2 - 4)^2+(-2 -2)^2 = 41[/tex]
[tex]52 \ne 41[/tex]
E.(4,-6)
[tex](4 - 0)^2+(-6 + 3)^2 = 41[/tex]
[tex]25 \ne 41[/tex]
[tex](4 - 4)^2+(-6 -2)^2 = 41[/tex]
[tex]64 \ne 41[/tex]

180(n-2)=s
solve for n
please help me
Answer:
n = (s + 360)/ 180
Step-by-step explanation:
180(n - 2)= s ? ummm ill try...
180n - 360 = s
180n = s + 360
n = (s + 360)/ 180
Answer:
n = s/180 +2
Step-by-step explanation:
180 (n-2) = s
Step 1: To find n, we need to get rid of 180 from the left side of the equation. Divide 180 by both sides; then we can cross out 180 with itself on the left, leaving (n-2)
180 (n-2) /180 = s/180
Step 2: Now we got rid of 180 on the left, we must isolate n. To do that, we must bring -2 to the other side of the equation. There, it would become positive, and n gets isolated.
n = s/180 + 2
Although, you may or may not be confused with my answer, and I realized that there's two ways to solve this. Let me show you:
Step 1: 180(n-2) = s
Distribute - multiply 180 with every term in the brackets, which then we would end up with:
180n-360 = s
Step 3: Bring -360 to the right side of the equation, where it would become positive.
180n = s+360
Step 4: To isolate n, divide 180 by both sides of the equation:
180n/180 = s+360/180
Step 4: Now you have:
n = s+360/180.
Though you could leave your answer as the one above, you should simplify it.
Step 5: n = s/180 + 360/180
360/180 = 2, therefore the simplified answer is:
n = s/180 +2

Here, a = 6x & b = 5
Area of a square = side * side
