Given:
Total number of students = 1400
The ratio of boys to girls is 3 to 4 for the school.
To find:
The number of boys and girls.
Solution:
We have, Boy : Girls = 3:4.
Let number of boys be 3x and number of girls be 4x.
Total number of students = 1400
Divide both sides by 7.
Now,
Number of boys 
Number of girls 
Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

Answer:
Step-by-step explanation:
The two angles are formed from 2 intersecting lines. The angles are called vertically opposite angles. They are equal
4x + 21 = 85 Subtract 21
4x = 85 - 21 Combine
4x = 64 Divide by 4
x = 64/4
x = 16
Answer:
The answer to your question is: # of times = 60.7
Step-by-step explanation:
data
7.4 billion people
each person occupied 13 inches
Earth circumference = 25000 miles
length of the lines = 13 in x 7.4 billion people
= 13 x 7 400 000 000
= 9.62 x 10 ¹⁰ in
Convert in to miles
1 mile --------------- 63360 in
x mi --------------- 9.62 x 10 ¹⁰ in
x = 1518308.1 mi
Now divide, the line of people by the circumference
# of times = 1518308.1 mi / 25000 mi = 60.7
Step 01:
Game show
Data:
$2300 computer system
$5400 luxury vacation
$8700 boat
Step 02:
Expected winnings
p (luxury vacation) = 0.20
p (boat) = 0.15
E (game show) = $1080 + $1305 = $2385
The answer is:
The expected winnings are $2385
