Answer:

12.5 feet

Step-by-step explanation:

He only needs 10/12 of a 15 foot long piece of wood. We need to find 10/12 of the length of the wood.

That is:

10/12 * 15 = 12.5 feet

He only needs 12.5 feet of the piece of wood.

IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE
boyakko [2]

Answer:

There are 600 students in this school.

Step-by-step explanation:

Let p represent the total population of the school.

Then (1/3)p represents the number of students who like math.  Subtracting this (1/3)p from p gives an expression representing those who do not like math:  

p - (1/3)p = (2/3)p

400 students do not like math, so (2/3)p = 400.

Solve this for p by multiplying both sides by (3/2):

(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.

There are 600 students in this school.

(19)<br> 82/47 = 82.8/x<br> 3891.6 = 82x<br> x = 47.4585<br> x = 47.5 meters
Ghella [55]
There are two ways (of many) to do this

Method 1:
47/x = 82/73.8
47*73.8 = 82x
3468.6 = 82x
82x = 3468.6
x = 3468.6/82
x = 42.3

---------------------------------

Method 2:
47/x = 92/82.8
47*82.8 = 92x
3891.6 = 92x
92x = 3891.6
x = 3891.6/92
x = 42.3

---------------------------------

Either way, the answer is 42.3 meters
