Answer:

60 students are divided into equal groups of 5 student each.

Groups of 5 students per group totaled up to 60 students.

The quotient in both expression is 60:5 = 12 students per group.

Step-by-step explanation:

The ratio expression is a way of expressing the division of numerator by a denominator.

Here,

The total number of students is the numerator = 60

The denominator is the number of students per group = 5

Hence, the quotient is the value of the divison obtained which is (60/2) = 12

Therefore, there are 12 groups of 5 students.

Answer:

10

Step-by-step explanation:

Use Pythagorean theorem,

Base² + altitude²= hypotenuse²

8² + altitude² = (2√41)²

64 + altitude² = 2²*(√41)²              {(√41)² = √41*√41 = 41}

64 +altitude² = 4 * 41

64 +altitude² = 164

      altitude² = 164 - 64

      altitude² = 100

      altitude = √100 = 10

Answer:

5 inches of wire costs 25 cents.

Step-by-step explanation:

To answer this question, we want to find the unit price per inch of wire. Therefore, we need to divide the cost of the 11 inches (55) by the length of the wire (11):

55 / 11 = 5

So, 1 inch of wire costs 5 cents.

Now, to see how many inches can be bought with 25 cents, multiply 5 times both the 1 inch and 5 cents, which are the unit price to get:

5 inches of wire costs 25 cents.

Answer:

Surveying To approximate the length of a marsh, a surveyor walks 250 meters from point  to point  , then turns  and walks 220 meters to point  (see figure). Approximate the length  of the marsh.

hope it helped

Step-by-step explanation:

The approximate length of the lake is 625 yards.

Given that, a surveyor starts at one end of the lake and walks 245 yards.

A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.

He then turns 110 and walks 270 yards until he arrives at the other end of the lake.

Total length of the lake is

245+110+270 =625 yards

Therefore, the approximate length of the lake is 625 yards.
