Let the number of cards equal x.
Set up an equation for both companies, set equal to each other and solve for x.
0.10x + 12 = 0.12x + 10
Subtractb0.10x from both sides:
12 = 0.02x + 10
Subtract 10 from both sides:
2 = 0.02x
Divide both sides by 0.02:
X = 2/0.02
X = 100
100 cards would be the same price for both companies.
7*2-3= 11
8*2-3= 13
9*2-3= 15
10*2-3= 17
the constant is bolded.
the equation is y=2x-3.
The sample would be where Greg searched so the sample is the local newspaper and the internet site
the population would be all available apartments
the answer would be
<span>A. Sample: listings in a local newspaper and on an Internet site
Population: all available apartments near the college</span>
Alright, so let's make a function for the number of seats in a row. Number of seats = 25+ (number of row-1)(2) because it goes up by two. We start with 25, so we have that, then we get that it adds by 2 every row. However, for the first row it only has 25, so we have the number of the row -1 .If we figure out the 200th row, we get 25+398=423. Adding that and 25, we get 448. 448*100=44800, and we get that number because with an even number of rows, we add the 1st and 200th, the 2nd and 99th, and so on. This works because as you go up rows, you add two, and as you decrease rows, you decrease by two, so they cancel each other out and form 100 pairs. All pairs are equal.
Answer:
The area of that bedroom in real life is of 216 square feet.
Step-by-step explanation:
Real dimensions:
One of the bedrooms on the blueprint is a rectangle measuring 3 inches by 4.5 inches.
The scale is that each inch on the drawing represents 4 feet in real measure.
So the dimensions of the bedroom are:
3*4 = 12 feet by 4.5*4 = 18 feet.
What is the area of that bedroom in real life?
Rectangular bedroom, so the area is the multiplication of the dimensions.
12*18 = 216 square feet.
The area of that bedroom in real life is of 216 square feet.
