There is a total of 30 erasers
Answer:
8:1
Step-by-step explanation:
Don reads 8 pages a minute. Therefore the amount of pages he could read is 8 and the amount of time it takes is a minute
Distribute
to every term inside the parentheses.
![50\cdotx^2+50\cdot7x+50\cdot6](https://tex.z-dn.net/?f=50%5Ccdotx%5E2%2B50%5Ccdot7x%2B50%5Ccdot6)
Simplify with multiplication.
![\huge\boxed{50^2+350x+300}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B50%5E2%2B350x%2B300%7D)
You can't simplify further by adding, so leave the answer as-is.
Y = mx + b
plug in the numbers.
y = 4/3 + 2
a) This part is already complete I think..
b) This is a cuboid and lateral surface area of cuboid is: 2(lb +bh + hl)
= 2( 10 × 3 + 3 × 7 + 7 × 10)
= 2(30 + 21 + 70)
= 2 × 121 = 242 cm²
Now, the area of top & bottom: lb
= 2 × 10 × 3
= 60 cm²
Neglecting the top & bottom surface area of cuboid:
= 242 - 60
= 180 cm²
c) The total surface area us 242.. I have already done that part above...
