Answer:

(A)

Step-by-step explanation:

Scott cycled for 10 minutes in first week, 15 minutes in second week,20 minutes in third week and 25 minutes in the fourth week which maintains a consistency in the line as there is consistent slope when drawn on a graph.

On, the other hand, harry cycled for 10 minutes in first week, 20 minutes in second, 40 minutes in third and 80 minutes in fourth week in which there is no consistency in the timings according to the weeks. Therefore, only, scott's method is linear as the number of minutes increased by an equal factor every week.

Tju [1.3M]

Answer:

She has 20 quarters.

Step-by-step explanation:

Alissa emptied her piggy bank for Disney world. She had $7.70.

If she had 10 pennies and twice as many times as quarters, then we can write the equation as

Q = 2P {Where, Q represents the number of quarters and P for pennies}

⇒ Q = 10 × 2

⇒ Q = 20

So, she has 20 quarters.

Therefore, she has 20 quarters. (Answer)

If f = {(2,5), (3, 2) (4, 6), (5, 1), (2, 2)), then f is a function.

KiRa [710]

Answer:

false

Step-by-step explanation:

f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

in a chemistry class, the ratio of girls to boys is 2 to 1. if there are 30 students in the class how many girls are there

VLD [36.1K]

Firstly, we can simplify the ratio of boys to girls to
1
:
2
.
Then, to find out how many students each ratio represents, we add up
1 and 2 to get 3
(1+2=3)
By dividing 3
by the number of students, we can find how many students ONE ratio represents:
24 3=8

So ONE ratio is equal to 8
boys. Since our simplified ratio of boys to girls is
1:2
already, we do not have to do further multiplying - the number of boys is simply 8.
For the girls, simply multiply 2 by 8 to get 16

Check: 8 boys + 18 girls = 24students
