Answer:

Your first 2 questions are correctly answered.

I think the answer to the third question is NO.

Step-by-step explanation:

You can see that the sides with 3 and 4 are adjacent, which means they cannot possibly be opposite. For a valid dice, they should be opposite because they add up to 7. Hence this net is not valid.

Mike can stitch 7 shirts in 42 hours. he can stitch 1 shirt in how many hours, and in 1 hour he can stitch how much of a shirt.

podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = $\frac{42}{7}$ = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = $\frac{1}{6}$ shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ shirts.

The circumference of a circle is 62.8 inches.Using pi as 3.14,what is the radius.PLEASE SHOW YOUR WORK!!!!

mamaluj [8]

The circumference of a circle - $C=2 \pi r$

$C=62.8 \\ \\
62.8=2 \times 3.14 \times r \\
62.8=6.28r \\ \frac{62.8}{6.28}=r \\ r=10$

The radius is 10 in.

What is the approximate volume of a right cone with a diameter of 10 meters and a height of 5 meters use 3.14 pie

ehidna [41]

First of all, it's not pie. It's pi.

Now, the problem.
Radius is always 1/2 x d (d meaning diameter)
That gives us 5.

The formula is 3.14 x 5^2(h/3)
If you solve it from left to right, you get 130.83
