Answer:
The model will be 6 toothpicks tall.
Step-by-step explanation:
your school is 30 feet tall and 1 feet is 1.26 cm, so you would most likely multiply 30 and 1.26 in order to get the height of the scale model which is 37.8 cm. Each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks So, for you to build the school, it would be 6 tp tall.
Answer:
Since the question doesn't mention in what tide the answer should be, I will be giving a solution to both, the high and low tide. Hope this helps :)
Step-by-step explanation:
Using a cosine function, where time is measured in hours past high
tide: y=4cos30x + 10
Using a cosine function, where time is measured in hours past low
tide: y = 4cos[30(x-6)]+10
Answer:
x > 
Step-by-step explanation:
given
2x > 7 ( isolate x by dividing both sides by 2 )
x > 
Answer:
A) B is greater
B) when C = 21, A = 5 and B = 15
C) A must be 0, 5, or 12 for C to be greater than B
Step-by-step explanation:
A) when a = -3, c = -20 and b = 4(-3)-5 so B = -17
B) when c = 21, a = 5 and b = 4(5)-5 so B = 15
C) C is greater than B when a = 0, 5, and 12
when a = 0, b = 4(0)-5 or -5
when a = 5, b = 4(5)-5 or 15
when a = 12, b = 4(12)-5 or 43
