Answer:
It will take 50,000 years to accumulate 5 centimeters of clay.
Step-by-step explanation:
The relationship between millimeter and centimer is that:
1ml = 0.1cm
So
How many ml are 5 cm?
1 ml - 0.1cm
x ml - 5cm
ml
Clay on the deep seafloor accumulates at a rate of about 1 millimeter per 1,000 years. How long would it take to accumulate 5 centimeters of clay?
5cm is 50 ml.
1 ml per 1000 years.
So
1 ml - 1000 years
50 ml - x years
It will take 50,000 years to accumulate 5 centimeters of clay.
Answer:
The percent increase is 20%.
Step-by-step explanation:
It's fairly simple.
Multiply 10 by (100/10) which is 10 to get 100.
Multiply 12 by 10 to get 120.
120 - 100 = 20
Answer:
- 15 @ 41 cents
- 50 @ 56 cents
Step-by-step explanation:
Let x represent the number of 41-cent stamps Yumi bought. Then the number of 56-cent stamps she bought was 4x-10. Her total purchase was ...
0.41x +0.56(4x -10) = 34.15
2.65x -5.60 = 34.15 . . . . . . . eliminate parentheses, collect terms
2.65x = 39.75 . . . . . . . . . . . . add 5.60
x = 15 . . . . . . . . . . . . . . divide by 2.65
4x-10 = 50
Yumi bought 15 41-cent stamps and 50 56-cent stamps.
