Answer:
1). 250 - 60t
2). 60t
Step-by-step explanation:
"Camila started her collection with 250 cards and decreased by 60 cards each year"
Starting number of cards with Camila = 250
Decrease in number of cards each year = 60
Decrease in number of cards after 't' years = 60t
Number of cards after 't' years = 250 - 60t
"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."
Number of cards with Camila = 0
Number of cards grew each year = 60
Number of cards after 't' years = 60t + 0 = 60t
Answer: I believe its 14/16 or if you want it to be simplified 7/8
Answer:
3
Step-by-step explanation:
Since D=8, you input it in
5(8)-25/5=
5(8)=40
40-25= 15
15 divided by 5 is 3
Answer:
36 Square Yards
Step-by-step explanation:
The Scale Drawing uses a ratio
2 Inches : 3 Yards
Therefore,
1 Inch = 3/2 Yards
If the area of the scale drawing is 16 Inch²
To get the area of the actual office, we multiply by the square of the scale factor.
Scale Factor=3/2
Therefore:
The area of the actual office space
=16X(3/2)² Square Yards
=36 Square Yards
Answer:
36 square yards.
Step-by-step explanation:
This question is solved with rule of three and ratios
We know that 2 inches is equivalent to 3 yards, and the area in the drawing is 16 square inches.
so if
2 inches ---- 3 yards then 1 inch is 3/2 yards.
Let's say that the office is 8 inches x 2 inches = 16 squared inches
Then, if we convert it to yards,
8 inches would be: yards
and 2 inches would be: yards
Then, the area of the office would be 12 x 3 = 36 squared yards.
