Answer:
Yes, she can.
Step-by-step explanation:
We have to find the surface area of the footrest and see if it greater than or less than 1 square yard.
The surface area of a rectangular prism is given as:
A=2(wl+hl+hw)
where w = width, l = length, h = height
The footrest is 15 inches by 7 inches by 9 inches. Its surface area is:
A = 2[(7 * 15) + (9 * 15) + (9 * 7)]
A = 2[105 + 135 + 63]
A = 2 * 303 = 606 square inches
1 square inch = 0.000771605 square yards
=> 606 square inches = 606 * 0.000771605 = 0.468 square yards
Since the surface area of the prism is less than 1 square yard, she can completely cover the footrest with the fabric.
Answer:
y=-1/2+2
Step-by-step explanation:
the y intercept is 2
Its negative because the slope is going down
1/2 because down 1 right 2
Answer:
397
Step-by-step explanation:
lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)
to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1
in this case we can find m easily (m = 21-17 = 4)
now we have c left so just sub one of the egs given to what we have alrd found
17 = 4(5) + c
17 = 20 + c
c = - 3
so the eqn is y = 4x - 3, and we can solve for when x = 100
y = 4(100) - 3
y = 397
hope this isn't too confusing :^)
