What should we find in order to determine how many square feet of plywood are needed to make a rectangular prism
Answers
Answer:
surface area
Step-by-step explanation:
A rectangular prism is an optical element which is transparent with flat sides that can pass or reflect light. A rectangular prism is a cube where all its sides are the same.
In the context, in order to find the total square feet of plywood needed to make a prism we have to determine its surface area.
The total surface area of a rectangular prism can be found out by the formula :
A = 2 (hl + lw + wh)
where, h = height of the rectangular prism
l = length of the rectangular prism
w = width of the rectangular prism

Answer:
Aonnalin, great name :) answer as below
Step-by-step explanation:
They tell us to use slope-intercept form. This is something you will just have to remember y = mx+b
It is confusing b/c there is the other one, the point-slope formula too. but just remember both and know that the point-slope one is to get to the slope-intercept one. y-y1 = m(x-x1)
m= slope
m = (y2-y1) / (x2-x1)
P1= (0,7) in the form (x1,y1)
P2 =(8,-2) in the form (x2,y2)
m = -2-7 / 8-0
m = -9 / 8
now that we have the slope, just use either point with the point-slope
y-7 = (-9/8)(x-0)
y-7 = -9x/8
y = -9x/8 + 7
y = [tex]\frac{-9}{8}[/tex] X + 7
slope-intercept form :)
I am not sure how to solve this. I have tried many times.

Determine the numerical value of x
Answers
Answer:
x = 10
Step-by-step explanation:
OA = OD ( both radii of the circle )
OD = OB + BD = x + 16
OB is at right angles to OB ( line from centre to midpoint of chord is right )
Using Pythagoras' identity in right triangle ABO
OA² = OB² + AB² , that is
(x + 16)² = x² + 24²
x² + 32x + 256 = x² + 576 ( subtract x² from both sides )
32x + 256 = 576 ( subtract 256 from both sides )
32x = 320 ( divide both sides by 32 )
x = 10

Answer:
11/4
Step-by-step explanation:
An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.
You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8
then we add 8/4 with 3/4 to get 11/4
