For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed

The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />

Toni is shopping for clothes at the store she buys 8 shirts for $8.00 what is the unit rate for the shirts?
lozanna [386]

Answer:

$1.00

Step-by-step explanation:

The unit rate in this scenario would be $1.00 , meaning that Toni is paying $1.00 for every shirt. This can be calculated by dividing the total price that she is paying for the shirts by the total number of shirts that Toni is purchasing like so...

$8.00 / 8 = $1.00 per shirt

The unit rate is basically the value over the denominator of 1 which would be the case as seen above since $1 buys 1 shirt (\frac{1 dollar}{1 shirt}) as opposed to $8 dollars 8 shirts (\frac{8 dollars}{8 shirts}) as mentioned in the question.

A balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20
stich3 [128]

Answer:

Step-by-step explanation:

given that a balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon

The distance of the boat from the balloon measured horizontally in the I position = 800 tan 20

After 25 seconds distance of the boat from the balloon measured horizontally in the II position

= 800 tan 65

Distance moved by the boat in 25 seconds

= 800(tan 65-tan 20)\\= 1342.56

Speed of the boat per second = \frac{1342.56}{25} \\=53.702

53.702 feet per second is the speed of boat
