Answer: d = 4t - 10
====================================================
Each side of the square picture frame is t centimeters long. The perimeter is t+t+t+t = 4*t centimeters long, which is just the entire distance around the frame. If we had the perfect amount of ribbon, then d = 4*t would be the end of the problem; however, we're 10 cm too short meaning that d is too small and it's actually d = 4*t - 10
For example, let's say that t = 12 meaning that the perimeter is 4*t = 4*12 = 48 cm. This would mean we have d = 4*t-10 = 4*12-10 = 48-10 = 38 cm of ribbon, and we're 10 cm too short (comparing 38 to 48).
note: d = 4t - 10 can be written as d = 4*t - 10
Answer: A. $754.10
Step-by-step explanation:
$320.00 + $486.88 = $806.88
$1,560.98 - $806.88 = $754.10
<u>1</u><u>5</u><u> </u><u>inches</u> is the height of the pyramid
Step-by-step explanation:
The volume of a cube is a³
Given <em>a</em> = 5 inches
→ Volume = a³
= 5³
= 5×5×5
= <u>125 in²</u>
The volume of a pyramid is 
Given a = 5 inches , h = height of pyramid
then,
Hence, the height of pyramid is <u>1</u><u>5</u><u> </u><u>inches</u>
