At a local preschool there is s as ratio of 3 boys to every 4 girls. If their are 245 total preschoolers enrolled how many are b
Zepler [3.9K]

Number of boys enrolled is 105

<em><u>Solution:</u></em>

Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls

There are 245 total preschoolers

Ratio of boys and girls = 3 : 4

Number of boys : number of girls = 3 : 4

Let the number of boys be 3x

Let the number of girls be 4x

Total number of preschoolers = 245

Therefore,

number of boys + number of girls = 245

3x + 4x = 245

7x = 245

x = 35

Number of boys = 3x = 3(35) = 105

Thus number of boys is 105

A right triangle has leg lengths of 7 inches and 24 inches.
SSSSS [86.1K]

Answer:

The length of the hypotenuse = 25 inches

Step-by-step explanation:

A right triangle has leg lengths of 7 inches and 24 inches.

Given

  • a = 7
  • b = 24

<u><em>Pythagorean Theorem</em></u>

For a right-angled triangle with sides 'a' and 'b', the hypotenuse 'c' is

defined as:

c=\sqrt{a^2+b^2}

  • a=7 inches
  • b=24 icnhes

so substituting the values

c=\sqrt{7^2+24^2}

c=25 inches

Thus, the length of the hypotenuse = 25 inches
