Answer:
C
Step-by-step explanation:
Graph C correctly shows that 5 cartons will have 5×12 = 60 eggs.
A. for the circumference it is C=pi(d)=pi(2r)=pi(10)= 31.4 ft
b. for the area it is A=pi(r)^2=pi(5)^2=pi(25)= 78.5 ft squared
c. since the are is 78.5 ft squared multiply by $4.50= $353.25 to floor the circle.
What you can do is multiply the whole first equation by 12, so 6x + 26.4y = 108.
then since the coefficients of the x value (the number in front of the x) are the same in both equations, you can subtract the second equation from the first:
6x + 26.4y = 108
-(6x + 0.4y = -22)
26y = 130 divide by 26
y = 5
you can then plug y=5 into one of the equations to solve for x:
0.5x + 2.2(5) = 9
0.5x + 11 = 9 subtract 11 from both sides
0.5x = -2 multiply each side by 2
x = -4
Answer:
False
Step-by-step explanation:
A square has two dimensions (length times width), whereas a cube has three (length times width times height). Therefore, "a cc is the space taken by a cube of side 1 cm."
Answer:
10.30p.m - 6.00a.m = 4.30
11.00p.m - 6.00a.m = 5.00
11.00p.m - 7.00a.m = 4.00
4.30 + 5.00 + 4.00 = 13.30
or you could do
4.30 + 4.00 = 8.30
8.30 + 5.00 = 13.30
13.30 = 1.30
I don't know if this is right, but i tried my best to help.
