Answer:
F' = (7, 6)
R' = (-1, 7)
I' = (-2, -5)
O' = (6, -6)
Step-by-step explanation:
The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.
Answer:
769.50
Step-by-step explanation:
95 ÷ 20 = 4.75
So, 4.75 is the cost per student
4.75 × 162 = 769.50
So, 4.75 dollars per student times 162 students is 769.50
Answer:
12. 524 in³ (3 sig. fig.) 13. 2000 cm³ (3 sig. fig.)
Step-by-step explanation:
12. Volume of sphere = (4/3)πr³
= 500/3π
= 524 in³ (3 sig. fig.)
13. Volume of cylinder = πr²h
= 7²π(13)
= 637π
= 2000 cm³ (3 sig. fig.)
Square root is the number that when multiplied when itself give the number you are looking for if that makes any sense.
8 is the square root of 64 because 8x8 = 64
Ok so first you take $64.80 and multiply it by 2.5. You get $162. Now take $162 and subtract $20 from it. You are left with $142.
