Answer:

Number of students who to prefer to practice after school are:

  84

Step-by-step explanation:

Seven of ten students polled say that they prefer to practice for a team sport after school than before school.

this implies that 7/10 part of the population prefer to practice for a team sport after school than before school.

Population of school=120

Hence, number of students who to prefer to practice after school are

             7×120/10

         =  84

Hence, 84 students prefer to practice after school

7/10 is 70%
70% of 120 is 84.

So 84 people would prefer to practice after school.

One argument against the American standard system of measurement is a lesser degree of accuracy than that of the metric system.
densk [106]
In this item, we are to divide one (1) inch into 16 equal parts to be able to conclude that American standard system is less accurate than the metric system. 
         16 parts of 1 inch = 1 inch / 16 = 0.0625 inch

This in itself is already a proof enough that there are 4 decimal places after the decimal point which makes this hard to properly measure.

Whereas, if we are to divide a centimeter into the millimeters, we will have 10 equal parts and that would be 1 mm = 0.1 cm.

The number above only has one decimal place and the level of accuracy should be higher.

3y= 21

I think 3y would be 21 because in the equation, 5y+13=48, y= 7. So if we know that y is 7 that’ll mean we’ll use 7 to interpret y for 3y.

Solve using the pathagorean theorem​
seropon [69]

Answer:

2 sqrt(13)

Step-by-step explanation:

We can find the hypotenuse using the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

4^2 + 6^2 = c^2

16+36 = c^2

52 = c^2

Taking the square root of each side

sqrt (52) = c

sqrt(4*13) = c

2 sqrt(13) = c
