I think it's the third one too
The answer is Square *8=h
I hope this helps.
Answer:
7. y
=
−
1
/2
x + 4
8. y= (0,4)
Step-by-step explanation:
7. the slope is -1/2 and the y intercept is 4
8. so basically, the y intercept is when y is zero, which makes this one (0,4)
HOPE THIS HELPS HAVE A GREAT DAY!!! IM procrastinating chem doing this lolz
Answer:
<h2>128m³</h2>
Step-by-step explanation:
Volume = L x W x H
L = 4
W = 4
H = 8
Volume = 4 x 4 x 8
Volume = 16 x 8 = 128m³
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! :)
