The circumference is about 12. This would been a bit easier if I knew the diameter.
Answer
- 1928 adults
explanation
- if you do 2408 plus 557 that would be 2965 but then 379 come off board so you do 2965 take away 379 that leads to 2586 and if 658 are kids u do 2586 take away 658 which leads to 1928 adults
Part A The equation to model this would be
240-( 240- 6.5x + 9) = y
x is the minutes the balloon decreases in altitude
Part B plug in x
240- (240 - 6.5(15) + 9) = y
y = 106.5
expression answer: 106.5
Part C altitude is 133.5 (240 - 106.5)
I need points sorry about this
Answer:
4
Step-by-step explanation:
they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x
