Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answers
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]

A square fits exactly inside of a circle with each of it's vertices being on the circumference of the circle. The square has sides of length x cm. The area of the circle is 56cm^2. Work out x
Answers
Answer:
[tex]5.971\ cm[/tex]
Step-by-step explanation:
The computation of x is given below:
As we know that
[tex]Area = \pi r^2\\\\56 = \pi r^2\\\\r^2 = \frac{56}{\pi} \\\\r = \sqrt{\frac{56}{\pi} }[/tex]
= 4.22
Now the diameter of the square would be similar to the diameter of the circle
So,
[tex]x\sqrt{2} = 2\times r \\\\x = \frac{2\times r}{\sqrt{2} } \\\\= \frac{2\times 4.22}{\sqrt{2} } \\\\= 5.971\ cm[/tex]

When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?
Answers
Answer: Rs. 25,300
Step-by-step explanation:
First find the original price of the plot:
Assume this price is x:
x * ( 1 - 15%) = 18,700
0.85x = 18,700
x = 18,700/0.85
x = Rs. 22,000
To make a gain of 15%, sell at:
= 22,000 * (1 + 15%)
= 22,000 * 1.15
= Rs. 25,300
Solve the simultaneous equations.

Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2

The map distance between joneville and smithtown is 1.8 in. The actual distance is 180 miles. What is the scale of this map?
Answers
Answer:
The scale is of 1:6336000
Step-by-step explanation:
The scale is given dividing the distance on the map by the real distance, in the same unit.
Each mile has 63360 inches.
We have that:
Distance on the map: 1.8 in
Real distance: 180 miles = 180*63360 = 11404800 in
Scale:
We have that 11404800/1.8 = 6,336,000, so the scale is of
1.8:11404800 = 1:6336000

[B] = -|A|, which matrix is matrix B?
Answers
Answer:
c
Step-by-step explanation:
Matrix B is [tex]\left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex].
Here, given condition is,
[tex]A = \left[\begin{array}{ccc}-2&5\\7&6&\\\end{array}\right][/tex]
And, l B l = - l A l
What is Matrix?
Matrix is an ordered rectangular arrangement of numbers.
Now,
[tex]A = \left[\begin{array}{ccc}-2&5\\7&6&\\\end{array}\right][/tex]
⇒ l A l = 6 x -2 - 5 x 7 = -12 - 35 = -47
Clearly, by option B;
[tex]B = \left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex]
⇒ l B l = 12 x 5 - 1 x 13
= 60 - 13 = 47
Hence, l B l = - l A l
So, Matrix B is [tex]\left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex].
