In a group of 48 children there are three times as many boys as girls. how many girls are there

Answers

Answer 1
Answer: if x=girls,
then we have 3x boys.

We know that all children are boys+girls, so x+3x, which is 4x and 4x is 48, so one x is 12.

So there are 12 girls and 36 boys.
Answer 2
Answer: There are x girls in the group.
There are three times as many boys as girls, so the number of boys is 3x.
There are 48 children in the group.

x+3x=48 \n4x=48 \nx=(48)/(4) \nx=12

There are 12 girls in the group.

Prizes $5 $10 $30 $50Number 10 10 5 5

Thirty people are eligible to win cash prizes. The number of each cash award prize is shown in the table. Prizes will be given out randomly one at a time. What is the probability of the first person winning the $50 prize?

Answers

Answer:

0.1667

Step-by-step explanation:

Given that the Total number of people who are eligible to win cash prizes is 30.From the given table we notice that 5 people win $50 cash prize.

The probability of the first person winning the $50 prize is therefore :

p=(Number \ who \ win \ \%50)/(Total \ no \ of \ people)\n\n=5/30\n\n=(1)/(6)=0.1667

Hence the probability of the first person winning the $50 prize is 0.1667

Find The area of The rectangle below \ 7 FT 6/10 FT

Answers

Lets first simplify the dimensions of the rectangle
length = 7
breadth = (6)/(10)(3)/(5) = 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6
  
Area of rectangle = 4.2

A total of 562 tickets were sold for the school play. They were either adult tickets or students tickets. There were 62 more student tickets sold than adult tick. how many adult tickets were sold ?

Answers

answer: there were 250 adult tickets sold.

explanation: write an equation for this problem.

x + (x + 62) = 562
keep in mind that x is the number of adult tickets, and (x + 62) is the number of student tickets.

now solve.

x + (x + 62) = 562.
2x + 62 = 562
2x = 562
x = 250

Answers

Answer:

J. -(1)/(36), (1)/(216), -(1)/(1296)

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

-36, 6, -1, (1)/(6),...

Here a_1=-36 and common ratio (r) = (-1)/(6)=(-1)/(6).

The formula we will use to find the next three terms is:

nth term = a_1 * r^((n-1))

5th term = -36 * (-1)/(6)^((5-1))  = -(1)/(36)

6th term = -36 * (-1)/(6)^((6-1))  = (1)/(216)

7th term = -36 * (-1)/(6)^((7-1))  = -(1)/(1296)

Answer:

J

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = (a_(2) )/(a_(1) ) = (6)/(-36) = - (1)/(6)

The next 3 terms are

(1)/(6) × - (1)/(6) = - (1)/(36)

- (1)/(36) × - (1)/(6) = (1)/(216)

(1)/(216) × - (1)/(6) = - (1)/(1296)
