Answer:

length of wire= 12.55m= 1255cm

Number of pieces= 50

length of each piece=?

length of each piece = 1255/ 50

length of each piece= 25.1cm= 0.251m

A soccer field measures 90 meters wide by 120 meters long starting together in one corner you walk the diagonal to the opposite

disa [49]

Answer:

The friend walks 60 m further than the other person

Step-by-step explanation:

Given the dimensions of the soccer field:

Width = 90 m

Length = 120 m

One person walks along its diagonal.

As the length and width of the field are perpendicular, Diagonal can be calculated using Pythagorean Theorem:

$Diagonal ^2 =Length^2+Width^2$

$Diagonal ^2 =90^2+120^2\\\Rightarrow Diagonal ^2 =8100+14400\\\Rightarrow Diagonal ^2 =22500\\\Rightarrow Diagonal =150\ m$

So, the distance walked by the person along the diagonal = 150 m

Distance walked by the person's friend to reach the opposite point = Width + Length = 120 + 90 = 210 m

So, the difference of the two distances will give us the distance that was walked further by the friend.

The difference is = 150 - 90 = 60 m

So, the friend walks 60 m further than the other person.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 48 cm³.

Taya2010 [7]

Answer:

32 cm³

Step-by-step explanation:

Volume of a sphere is:

$V_{s}=\frac{4}{3}\pi r^{3}$

Volume of a cylinder is:

$V_{c} = \pi r^{2} h$

The volume of the cylinder is 48 cm³.

The cylinder has the same radius (r) and height (2r) as the sphere.

$48 = \pi r^{2} (2r)\\48 = 2\pi r^{3}\\24 = \pi r^{3}$

Therefore, the volume of the sphere is:

$V_{s}=\frac{4}{3} (24)\\V_{s}=32$

kati45 [8]

Question:

Morgan is playing a board game that requires three standard dice to be thrown at one time. Each die has six sides, with one of the numbers 1 through 6 on each side. She has one throw of the dice left, and she needs a 17 to win the game. What is the probability that Morgan wins the game (order matters)?

Answer:

1/72

Step-by-step explanation:

Morgan can roll a 17 in 3 different ways. The first way is if the first die comes up 5, the second die comes up 6, and the third die comes up 6. The second way is if the first die comes up 6, the second die comes up 5, and the third die comes up 6. The third way is if the first die comes up 6, the second die comes up 6, and the third die comes up 5. For each way, the probability of it occurring is 1/6 x 1/6 x 1/6 = 1/216. Therefore, since there are 3 different ways to roll a 17, the probability that Morgan rolls a 17 and wins the game is 1/216 + 1/216 + 1/216 = 3/216 = 1/72

I had this same question on my test!

Hope this helped! Good Luck! ~LILZ
