Surface area = 2 pi (3x-2)^2 + 2 pi (3x -2) ( x + 3)
= 2 pi (9x^2 - 12x + 4 + 3x^2 + 7x - 6
= 2pi(12x^2 - 5x - 2)
Its D
Y = 6x
4x + y = 7
(substitute y = 6x in the ‘y’ spot in 4x + y = 7)
4x + 6x = 7
10x = 7
/10 on both sides
x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)
y = 6x
y = 6(7/10)
y = 4.2 = 21/5
Answer:
x = 7/10
y = 21/5
Answer:
44 euros
Step-by-step explanation:
if the ratio between an english pound and a euro is 3 to 4 respectivley, the ratios will hold true for any number. Since 33/3 = 11, we can stratigically multiply by 1,
3/4 = (3/4)(11/11)
so the ratios would be the same, multiplying, you would get 33/44, which means 33 pounds for 44 euros
Answer:
244 students.
Step-by-step explanation:
Okay, so. We know 150 people of the 7th grade is coming and 62.5% is the entire of the 7th graders coming. We would multiply.
150 * 62.5% = 93.75
We would round it up. It is over 5, so it would be 94 students. Then we would add
150 + 94 = 244
There are 244 students in 7th grade.
