There are 105 in 6th grade because there are 75 boys right? So it said the ratio of girls is 7 and the ratio of boys is 5 so I divided 75 to 5 = 15 and I multiply 7 to 15 and got 105 girls.
The area of the square whose sides is s inches long will be given by:
Area=length×width
Length=s inches
width=s inches
thus:
the area of the squares will be:
Area=s×s=s² sq. inches
Thus the correct answer is:
area=s² sq. in
-- The area of the long skinny piece on top is (6 x 33) = 198
-- The length of the dotted line between the top and bottom pieces is (33-21) = 12
-- The area of the bottom piece is (12 x 15) = 180
-- The area of the whole thing is (198 + 180) = 378
-- The perimeter of the whole thing is (33 + 6 + 21 + 15 + 12 + 15 + 6) = 108
Answer: The amount that Kristen would owe three months from now is $67.5
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or the current balance.
R represents interest rate
T represents the duration for which the account is overdue in years.
From the information given,
P = 1500
R = 18%
T = 3 months = 3/12 = 0.25 year
I = (1500 × 18 × 0.25)/100 = $67.5
The answer’s c, y=5/2x+10
