The radio of boys to girls at a middle school is 3 : 2 what is the ratio of girls to all students.

Answer:

12.25 un

Step-by-step explanation:

-the formula for the area of a triangle is A=(1/2)bh or Area=(1/2)×Base×Height

to find the base you need to take 7.5 and subtract 2.5 the divide in half for each base of the triangles to get 2.5 for the bases.

then take your formula and multiply:

0.5×2.5×2.5=3.125×2=6.25 and you get the area of the triangles.

then do the area of the center square which is:

2.5×2.5=6 for the center

then add:

A=6.25+6=12.25

Answer:

.55 or 11/20

Step-by-step explanation:

multiply 2 3/4 by 1/5 to get the pounds of apples Sage uses.

Sage uses 11/20 of a pound of apples or approximately 0.55 pounds of apples.

A fraction with a mixed expression, also known as a complex fraction, has a fraction in either the numerator, the denominator, or both.

The box contains 2³/₄  pounds of apples, which can be written as a mixed number or an improper fraction:

2³/₄ = (2 × 4 + 3)/4 = 11/4

To find out how many pounds of apples Sage uses, we need to multiply the amount in the box by the fraction that represents the proportion of the box that Sage uses, which is 1/5:

(1/5) × (11/4) = (1 × 11)/(5 × 4) = 11/20

Therefore, Sage uses 11/20 of a pound of apples or approximately 0.55 pounds of apples.

Answer:

t = (p - 1/2)/3

Step-by-step explanation:

p = 4t + 1/2 - t​

combine like terms:

p = 3t + 1/2

subtract 1/2 from each side of the equation:

3t = p - 1/2

divide both sides by 3:

t = (p - 1/2)/3

Answer: Question 10 is c

Question 11 is c

Step-by-step explanation: Area of a circle is πr^2 so we know what the radius r is, it is 9.5 so we plug it in π(9.5)^2

Question 11 To get the radius from the diameter we need to know the half of the diameter which is 21=r

So we plug in 2πr is the equation for the circumference 2π(21) which then would be c

Answer:

1/12

Step-by-step explanation:

if Mr.Tough can grade 1 in 12 hours he can do 1/12

The fraction of the exams that Mr Tough and Mrs Nice grade in 1 hour if they work together is 3/20

A fraction is used to denote a portion or component of a whole. Numerator and denominator are the two components that make up a fraction. There are three types of fractions: proper, incorrect, and mixed.

Using, rate × time = work done

So, Mr Tough's rate:

Mr Tough's rate × 12 hours = final exam

Mr Tough's rate = 1/12

and, Mrs. Nice's' rate:

Mrs .Nice's' rate × 15 hours = final exam

Mrs .Nice's' rate = 1/15

So, Total time:

T(1/12 hours + 1/15 hours) = final exam

T =  final exam / (1/12 + 1/15)

T =  final exam / (0.15)

Now, 1 hour =  final exam / (0.15)

final exam = 1 × 0.15

                = 0.15

                = 15/ 100

                = 3/20

Therefore, 3/20 fraction of the final exam.
