The question states that both parts of Noshi's desk were shaped like trapezoids and both had a height of 3.
We know that the formula for area of a trapezoid is (a+b)/2 * h, where a and b are bases of the trapezoid and h is the height. Note: This is like any other form of trying to find the area, because we are doing base times height, however, we need to divide the sum of the bases by 2 to find the average base length.
Let's call the first trapezoid on the left Trapezoid A and the second slanted trapezoid Trapezoid B.
Area of Trapezoid A = (a+b)/2 * h = (5+8)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet
Area of Trapezoid B = (a+b)/2 * h = (4+9)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet
To find the area of Noshi's total desk, we simply need to add the areas of Trapezoid A and Trapezoid B together.
19.5 feet + 19.5 feet = 39 feet
Therefore, the area of Noshi's desk is 39 feet.
Hope this helps! :)
There are 10 pairs of shoes. 8 shoes are select.
<span>P = (2/20) (2/19) (2/18) (2/17) (2/16) (2/15) (2/14) (2/13) </span>
<span>P = 2^8 / (20P8) </span>
<span>But, any 8 differents shoes can be chosen from 10 pairs. </span>
<span>so there are 10C8 = 45 ways to do so </span>
<span>P = 45 * 2^8 / (20C8) </span>
<span>But, since order does not matter, there are 8! way you can select the 8 different shoes </span>
<span>P = 8! * 45 * 2^8 / (20C8) </span>
<span>P = 384/4199 or about 9.145%</span>
Answer:
15
Step-by-step explanation:
7.5 divided by 0.5 = 15
Answer:
The rate of change would be -6
Step-by-step explanation:
y2-y1/x2-x1
-4-8/0+2= -6
This can be proven by using the equation
y= -6x-4
y= -6(-2)-4
y= 12-4
y= 8

Answer:
X=60
Step-by-step explanation:
Hello There!
The angle labeled 80 and the angles labeled x and 20 are alternate interior angles meaning that they are congruent
So
80=20+x
step 1 subtract 20 from each side
80-20=60
we're left with
x=60
