Answer:
he spent $0.15 on each pencil
Step-by-step explanation:
12x4= 48, which is the exact amount of pencils he bought, and then divide them by the price
7.20 divided by 48 is 0.15.
Therefore, each pencil is 0.15 cents a piece
Area = πr^2
Circumference = 2πr
Blue:
Area = 5^2 = 25π
Circumference = 2 * 5 * π = 10π
Pink:
Area = 6^2 = 36π
Circumference = 2 *6*π = 12π
White:
r = 3
Area = 3^2 = 9π
Circumference = 2 *3 = 6π
Red:
Area = 7^2 = 49π
Circumference = 2 *7 = 14π
Answer:
A
Step-by-step explanation:
Find the rise over run (gradient) between two points. Choosing x=-2 and x=1 we get (1 - - 2) / (4 - 7) = -3/3 = -1. This means that m in y=mx+c is -1 so it is either A or C. If we then try a pair of x and y with y = -x + c we can get c. Using the first pair: 7=-1*-2+c = 2 + c so c = 5, leaving us with y = -x + 5.
Alternatively try all 4 with the numbers, if plugging in that value of x gives you that value of y then it is the correct equation.
Answer:
4 boxes (Brainliest Please)
Step-by-step explanation:
You have to find the amount of students
24 X 13 = 312
You have to get enough for everybody so you need 400 shirts so that everyone can get one.
400 / 100
4 boxes
