We can calculate the percent change dividing the change by the original amount of people attending the exhibit.

The increase is 298-152 = 146.

Then, we can calculate the percent change as:

\frac{298-152}{152}=\frac{146}{152}=0.9605=96\%

There was a 96% increase in the number of people attending the exhibit.

If Jaime is riding at 14 miles per hour and Cori is riding at 0.40 km per minute, how far will each of them bike in two hours? 1
natali 33 [55]

Answer:

Jaime: d = 45.08\ km

Cori: d = 48km

Step-by-step explanation:

Given

V_1 = 14\ miles/hour

V_2 = 0.40\ km/hour

Time\ (t)\ = 2\ hours

Solving Jaime Distance;

d = vt

Substitute values for v and t

d = 14\ miles/hour * 2\ hours

d = 28\ miles

Convert to kilometer

d = 28 * 1.61\ km

d = 45.08\ km

Solving Cori Distance:

d = vt

Substitute values for v and t

d = 0.40km/min * 2\ hours

Convert hours to minute

d = 0.40km/min * 2 * 60\ min

d = 0.40km * 2 * 60

d = 48km

andrea drove 200 miles using 9 gallons of gas. At this rate, how many gallons of gas would she need to drive 420 miles?
Anika [276]

Given : Andre drove 200 Miles using 9 Gallons of Gas

⇒ Andre drives 1 Mile using [\frac{9}{200}]\;Gallons\;of\;Gas

⇒ Andre drives (420 × 1 Mile) using [\frac{420\times9}{200}]\;Gallons\;of\;Gas

⇒ Andre drives 420 Miles using 18.9 Gallons of Gas

15 PINTS!!!!!!!!! PLZ HELP!!!!!!!! The linear function f(x) = 0.5x + 80 represents the average test score in your math class, wh
Stells [14]

Answer:

Part A: The test average for the math class after completing 2 tests is 81

Part B: The test average for the science class after completing 2 tests is 83

Part C: The science class had the higher average test score after completing the test 4.

Step-by-step explanation:

The average test score for math class is given by the linear function, f(x) = 0.5·x + 80

The data for the average test score for science g(x) are;

x,   q(x)

1,     81

2,    83

3,    85

Part A: The average test score for math after completing test 2 is given as follows;

f(2) = 0.5×2 + 80 = 81

∴ The test average for the math class after completing 2 tests = 81

Part B:

The average test score for science after completing test 2 is given from the table as at x = 2, g(2) = 83

∴ The test average for the science class after completing 2 tests = 83

Part C: After completing 4 tests, we have for the math class, f(4) = 0.5×4 + 80 = 82

For the science class, it is observed that common difference between each subsequent test score average is 2, therefore, the average test score, for the fourth test is 2 added to the average test score after the third test, which gives;

Average test score, after completing the fourth test for the science class, g(4) = 85 + 2 = 87

Since g(4) > f(4) the science class had the higher average test score after completing the test 4.
