Answer:
71 girls
Step-by-step explanation:
The class has 100 students.
It consists of 13 girls with no boyfriends, and the rest are "triplets" (B+2G groups)
If we subtract the 13 girls, the triplets must add up to 87 students.
The number of triplets is 87/3 = 29.
29(B + 2G) = 29B + 58G
The triplets consist of 29 boys and 58 girls with boyfriends.
No. of girls = girls with boyfriends + girls with no boyfriend
= 58 + 13
= 71
There are 71 girls in the class.
The distance from A to B is the radius, as point A is the center of the circle, and B is a point on the circle.
AB is 5 inches, so the radius will be 5 inches.
D is another point on the circle, so AD would also be considered a radius. This means that the distance from A to D would be 5 inches.
Answer:
2044 cups
Step-by-step explanation:
number of cups left = number of cups in the watering can - number of cups remaining
convert the capacity of the watering can to cups
1 quart = 4 cups
512 x 4 = 2048
2048 - 4 = 2044
The answer is 4g^2-12g+9
(2g+-3)(2g+3)
(2g)(2g)+(2g)(-3)+(-3)(2g)+(-3)(-3)
Using synthetic division, with divisor -4 stemming from factor (x+4), we find the coefficients of the quotient:
____________________
-4 / -3 -4 2
12 -2
------------------------------------
-3 8 0
The quotient is then -3x + 8, using the coefficients derived using synth. div.
