Answer:
for part A its C and for B its 2
Step-by-step explanation:
The total is 28 and there is 13 points total so you have to do 28/13
1:
A has volume 9*6*5=270 and surface area 2*(9*6+9*5+6*5)=258.
B has volume 9*3*10=270 and surface area 2*(9*10+9*3+3*10)=294.
D is the correct answer.
2: The surface area is 2*(6*8+6*13+8*13)=460.
3: The area of one of the triangular areas is 5*24/2=60, the area of one of the upper rectangles is 13*16=208, and the area of the lower one is 16*24=384.
There are two triangles, two upper rectangles, and one lower rectangle, so we have a total of 60*2+208*2+384=920.
4: The bottom square has area 30*30=900, and each upper triangle has area 30*45/2=675. We have four triangles and one square, so our answer is 675*4+900=3600.
Answer: 2nd
plots fit the red line closer than the 1st
Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation
-----> equation
Substitute equation in equation
find the value of x
therefore
the answer is
Sari has erasers
