Answer:
E. 54cm ^2
Step-by-step explanation:
when finding the area just multiply length over width .for example 9 is the length times it to the width 6 you get 54 so the area will be 54 cm
This question is easy if you think about it. First get the area of the rectangular part of the shape and then find area of the two semi-circles then add them together.
First, let's solve for the rectangle because it's easier.
Area for finding a rectangle A = w * l
A = 23 * 37
A = 851
Now for the semi-circle. First use the equation for finding the area of a circle which is A = Pi * r^2. We'll use 3.14 for Pi.
We know the diameter is 23. And to get the radius we just half it because the radius is half of the diameter.
23 / 2 = 11.5
A = 3.14 * 11.5^2
A = 3.14 * <span>132.25
</span>A = <span>415.265
</span>
Now we have the total area for both semi-circles. Because if we half 415.265 then add the other semi-circle's area it will be the same and adding them up will result in 415.265.
Now add up 851 and 415.265.
851 + 415.265 = <span>1266.265</span>
Answer:
<em>(1). A = 18 cm² ; (2). TR = 18 units</em>
Step-by-step explanation:
Answer: The value of the y-intercept is 
Step-by-step explanation:
The equation of the line in Slope-intercept form is:
Where "m" is the slope and "b" is the y-intercept.
In this case we know that the line passes through point 
and has a slope of 
. Then we can substitute the following values into :
Then:
And finally, we must solve for "b":
Step-by-step explanation:
A. to make the quadrilateral a parallelogram, we have:
7y + 5 = 8y - 4
112 = 10x - 8
<=> y = 5 + 4
120 = 10x
<=> x = 12
y = 9
B.we have:
17 = 4x + 5
63 = 8y - 1
<=> 12 = 4x
64 = 8y
<=> x = 3
y = 8
