Answer:
answer is sheet cake aka B on edge
Step-by-step explanation:
You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504
Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.
Answer:
s = 4
Step-by-step explanation:
3r = 10 + 5s
3×10 = 10 + 5s
5s = 30 - 10
5s = 20
s = 20 : 5
s = 4
Answer: (9,18)
Step-by-step explanation: Graph it mark your midpoint and see the difference between them and do it on the opposite sirrection and you should get it
Hello : let h =f(t)
<span>the ball hit the ground if : f(t) =0
solve : </span><span> -16t² + 20t + 6=0
</span><span>Δ = b²-4ac ... a = -16 b= 20 c =6
</span>Δ =(20)²-4(-16)(6) = 784 = 28²
t1 = (-20-28)/-32 = 48/32 =3/2
t2 =(-20+28) /-32 <span>< 0 refused
conclusion : t=3/2</span>
