Answer:
Step-by-step explanation:
Answer: 2.3
Step-by-step explanation:
Janet can make 3/4 of a necklace in 10 minutes.
<u>We need to find how many necklaces she can make in 1 hour.</u>
1 hour = 60 minutes
<u>We can rewrite it as:</u>
1 hour = 3*(20 minutes)
So Janet can create three 3/4 necklaces in 1 hour
Therefore, the total necklaces Janet can make in 1 hour = 3*(3/4) = 9/4 = 2.25
To the nearest tenth of a necklace = 2.3 necklaces
Part A:
13²-5²=c
169-25=144
√144=12
Your height is 12.
Part B:
Base:
20(10)=200
Two triangular faces:
5(13)=65
65(2)=130
Rectangular faces:
20(13)=260
260(2)=520
200+130+520=850
They would need 850 cm of cardboard.
Hope this helps! Have an amazing day!
