Answer:
C. 36 square centimeters.
Explanation:
The area of a trapezoid is calculated using the formula below:
\(\begin{gathered} A=\frac{1}{2}(a+b)h \\ a\text{ and b are the two parallel sides} \\ h=\text{perpendicular height} \end{gathered}\)Substitute the given values:
\(\begin{gathered} A=\frac{1}{2}(5+7)6 \\ =\frac{1}{2}\times12\times6 \\ =36\text{ square centimeters} \end{gathered}\)The area of each trapezoid is 36 square centimeters.
A rectangle has a length that is three times the width . The perimeter of the rectangle is 40 feet.what is the area of the rectangle
Answer:
The area is 15 feet
Step-by-step explanation:
So you are going to need two different equations-
l = w(3)
2l + 2w = 40
Insert the first equation into the second-
2(3w) + 2w = 40
Simplify this equation-
6w + 2w = 40
8w = 40
Divide both sides by 5
w = 5
Solve first equation
l = 5(3)
l = 15
Then find the area-
5 x 15 = 75

a plane flies 5.0km due north from a point O and then 6.0km on a bearing of 060° the pilot then changes course on a bearing of 120° for 4.0km. find how far and in what direction the plane is from the starting point?
The plane flies a distance of approximately 10.536 kilometers in straight line and with a bearing of approximately 035°.
A plane that travels a distance \(r\), in kilometers, with a bearing of \(\theta\) sexagesimal degrees can be represented in standard position by means of the following expression:
\(\vec r = r\cdot (\sin\theta, \cos \theta)\) (1)
We can obtain the resulting vector (\(\vec R\)) by the principle of superposition:
\(\vec R = \Sigma_{i=1}^{n} [r_{i}\cdot (\sin \theta_{i}, \cos \theta_{i})]\) (2)
If we know that \(r_{1} = 5\,km\), \(\theta_{1} = 0^{\circ}\), \(r_{2} = 6\,km\), \(\theta_{2} = 60^{\circ}\), \(r_{3} = 4\,km\) and \(\theta_{3} = 120^{\circ}\), then the resulting vector is:
\(\vec R = 5\cdot (\sin 0^{\circ}, \cos 0^{\circ}) + 6\cdot (\sin 60^{\circ}, \cos 60^{\circ}) + 4\cdot (\sin 120^{\circ}, \cos 120^{\circ})\)
\(\vec R = (5\sqrt{3}, 6) \,[km]\)
The magnitude of the resultant is found by Pythagorean theorem:
\(\|\vec R\| = \sqrt{R_{x}^{2}+R_{y}^{2}}\)
And the bearing is determined by the following inverse trigonometric relationship:
\(\theta_{R} = \tan^{-1} \left(\frac{R_{y}}{R_{x}}\right)\) (3)
If we know that \(R_{x} = 5\sqrt{3}\,km\) and \(R_{y} = 6\,km\), then the magnitude and the bearing of the resultant is:
\(\|\vec R\| = \sqrt{(5\sqrt{3})^{2}+6^{2}}\)
\(\|\vec R\| \approx 10.536\,km\)
\(\theta_{R} = \tan^{-1} \left(\frac{6}{5\sqrt{3}} \right)\)
\(\theta_{R} \approx 34.715^{\circ}\)
The plane flies a distance of approximately 10.536 kilometers in straight line and with a bearing of approximately 035°.

Using simultaneous equation, the solution to the system of linear equations are 1223 $10 tickets, 1332 $20 tickets, and 763 $30 tickets were sold.
How many tickets of each kind has been sold?Let's solve the problem step by step.
Let:
x = number of $10 tickets sold
y = number of $20 tickets sold
z = number of $30 tickets sold
From the given information, we can form the following equations:
Equation 1: x + y + z = 3318 (Total number of tickets sold)
Equation 2: y = x + 109 (109 more $20 tickets than $10 tickets were sold)
Equation 3: 10x + 20y + 30z = 61760 (Total sales from ticket sales)
We can use these three equations to solve for the values of x, y, and z.
First, let's substitute Equation 2 into Equation 1:
x + (x + 109) + z = 3318
2x + 109 + z = 3318
2x + z = 3209 (Equation 4)
Now, let's substitute the value of y from Equation 2 into Equation 3:
10x + 20(x + 109) + 30z = 61760
10x + 20x + 2180 + 30z = 61760
30x + 30z = 59580
x + z = 1986 (Equation 5)
We now have a system of equations (Equations 4 and 5) with two variables (x and z). We can solve this system to find the values of x and z.
Multiplying Equation 4 by 30, and Equation 5 by 2, we get:
60x + 30z = 96270 (Equation 6)
2x + 2z = 3972 (Equation 7)
Now, subtract Equation 7 from Equation 6:
(60x + 30z) - (2x + 2z) = 96270 - 3972
58x + 28z = 92298
Simplifying, we have:
29x + 14z = 46149 (Equation 8)
Now, we can solve Equations 5 and 8 simultaneously:
x + z = 1986 (Equation 5)
29x + 14z = 46149 (Equation 8)
Multiplying Equation 5 by 14, and Equation 8 by 1, we get:
14x + 14z = 27804 (Equation 9)
29x + 14z = 46149 (Equation 8)
Now, subtract Equation 9 from Equation 8:
(29x + 14z) - (14x + 14z) = 46149 - 27804
15x = 18345
Divide both sides of the equation by 15:
x = 18345 / 15
x = 1223
Substituting the value of x into Equation 5, we can find z:
1223 + z = 1986
z = 1986 - 1223
z = 763
Now that we have the values of x and z, we can substitute them back into Equation 1 to find y:
1223 + y + 763 = 3318
y + 1986 = 3318
y = 3318 - 1986
y = 1332
Therefore, the solution to the problem is:
x = 1223 (number of $10 tickets sold)
y = 1332 (number of $20 tickets sold)
z = 763 (number of $30 tickets sold)

K is between J and M. M is between K and N. N is between M and L. JN = 14 , KM = 4 , and KM = MN = LN . 13. Draw the segment and show the location of each point.
Answer:
JK = 6
NL = 4
Step-by-step explanation:
J > K > M > N > L
JN = 14
KM= 4
MN = 4
LN = 4
JN - KM -MN= JK
14-4-4=JK
JK = 6
if 3 measures are 4 then this is showing radius split into two sectors
JK therefore is segment 1 = 6
KM therefore is segment 2 = 4
MN therefore is the sector radius from M = 4
NL therefore is the sector radius from N to L which meets J and = 4 as it is an end line of the segment.

The total length of the centre circle and the two goal semi circles to be repainted is 56.22 meters.
How to calculate the Calculate the total length of the centre circle and the two goal semi circles to be repaintedGiven:
Court lines are 50 mm wide.
Court paint covers 7 m² per litre of paint.
The centre circle is a complete circle, so the circumference is given by the formula: Circumference = 2πr
Radius of the entire circle = 9 m / 2 = 4.5 m
Radius of the centre circle = 4.5 m - 0.05 m (converted 50 mm to meters) = 4.45 m
Circumference of the centre circle = 2π(4.45 m) = 27.94 m
Next, let's calculate the circumference of the semicircles:
The semicircles are half circles, so the circumference is given by the formula: Circumference = πr
The radius (r) of the semicircles is the same as the radius of the entire circle, which is 4.5 m.
Circumference of a semicircle = π(4.5 m) = 14.14 m
Total length = Circumference of the centre circle + 2 x Circumference of a semicircle
Total length = 27.94 m + 2(14.14 m)
Total length = 56.22 m
Therefore, the total length of the centre circle and the two goal semi circles to be repainted is 56.22 meters.

If lines, KI and LY, intersect at point A and m/KAY=4x+39, m/LAI=12x-9, what is m/YAI?
Answer:
0 degrees
Step-by-step explanation:
To find m/YAI, we need to first find the measure of angle KAI, which is the sum of angles KAY and LAI. Then, we can find the measure of angle YAI by subtracting the measure of angle KAI from 180 degrees.
Using the angle addition postulate, we know that:
m/KAY + m/LAI = m/KAI
Substituting the given values, we get:
4x + 39 + 12x - 9 = m/KAI
Simplifying the expression, we get:
16x + 30 = m/KAI
Now, we need to solve for x. To do this, we can use the fact that angles KAY and LAI are supplementary (add up to 180 degrees) since they form a straight line. Thus:
m/KAY + m/LAI = 180
Substituting the given values, we get:
4x + 39 + 12x - 9 = 180
Simplifying the expression, we get:
16x + 30 = 180
Subtracting 30 from both sides, we get:
16x = 150
Dividing both sides by 16, we get:
x = 9.375
Now that we know x, we can substitute it back into the equation we found earlier:
16x + 30 = m/KAI
16(9.375) + 30 = m/KAI
150 + 30 = m/KAI
m/KAI = 180
So, we know that angle KAI measures 180 degrees. To find m/YAI, we need to subtract the measure of angle KAI from 180 degrees:
m/YAI = 180 - m/KAI
m/YAI = 180 - 180
m/YAI = 0
Therefore, we can conclude that the measure of angle YAI is 0 degrees. This means that YAI is not an angle, but a line segment, and it does not have a measure in degrees.
