Answer:
33.5% of commuters took public transportation in San Francisco.
Step-by-step explanation:
Let p be the percentage of commuters took public transportation in San Francisco.
Given: 53.4% of commuters took public transportation in New York City, which was 19.9% greater than the percentage in San Francisco.
That means,
53.4 = 19.9 + p
Hence, required equation :
Subtract 19.9 from both sides , we get
hence, 33.5% of commuters took public transportation in San Francisco.
Answer:
Dilation factor is 2/3
Step-by-step explanation:
Look at both flat lines (M to S and M' to S') and find their lengths.
M to S = 9 units
M' to S' = 6 units
The triangle has gotten smaller so the dilation factor is a fraction
new/original = 6/9 = .66666666 or 2/3
Dilation factor is 2/3
X=quarters, y=dimes
7+2x=y
0.25x+0.1y=10.15
we substitute the first equation into the second equation
0.25x+0.1(7+2x)=10.15
0.25x+0.7+0.2x=10.15
0.45x+0.7-0.7=10.15-0.7
0.45x=9.45
0.45x/0.45=9.45/0.45
x=21 quarters
7+2x=y, x=21
7+2(21)=y
7+42=y
y=49 dimes
check: 0.25x+0.1y=10.15 when x=21, y=49
21(0.25)=5.25 in quarters
49(0.1)=4.90 in dimes
5.25+4.90=10.15
Answer:
The second set.
Step-by-step explanation:
Consider the first set of ordered pairs.
For an increase of 9 is the x-values the y values increases by 1.
In the case of the second set the increase in y values compared with increase in y values is different:
x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y for every unit of x.
x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.
