Answer:
The inequality 15m + 120 ≥ 200 represents the situation.
Step-by-step explanation:
Given that:
Diego started savings account with $120.
Amount deposited each month = $15
Number of months = m
The least balance he wants to have = $200
Amount deposited each month * No. of months + Amount deposited at start ≥ Least amount of balance
15*m + 120 ≥ 200
15m + 120 ≥ 200
Hence,
The inequality 15m + 120 ≥ 200 represents the situation.
Answer:
2/45
Step-by-step explanation:
First chooses a polka dot shirt: 2 / (5+6+2+2) = 2/15
Then a striped shirt, after replace: 5/15 = 1/3
the probability that she chooses a polka dot shirt then a striped shirt:
2/15 x 1/3 = 2/45
He should change the coefficient 5
Answer
Find the volume of the coin is cubic millimeters.
To prove
Formula

Where r is the radius and h is the height .
As given
The $1 coin depicts Sacagawea and her infant son.
The diameter of the coin is 26.5 mm, and the thickness is 2.00 mm.


Radius = 13.25 mm

Put in the formula
Volume of coin = 3.14 × 13.25 × 13.25 × 2.00
= 1102.53 mm³ (approx)
Therefore the volume of the coin is 1102.53 mm³ .
