Answer:
She would receive 96 points
Step-by-step explanation:
The grade (Y) received on a certain teacher's 100-point test varies in direct proportion to the amount of time(t) a student spends preparing for the test.
Mathematically
Y= kt
Where k is constant of proportionality
If y= 72 and t= 3
72=k3
72/3= k
24= k
So
Y= 24t
If t= 4
Y= kt
Y= 24(4)
Y= 96
Y = 96 points
She would receive 96 points

Answer:
24 bouquet
Step-by-step explanation:
300 divide by 12.50
Answer:
x ≤−9
Step-by-step explanation:
2x+15≤x/3
Simplify both sides of the inequality.
2x+15≤1/3x
Subtract 1/3x from both sides.
2x+15−1/3x≤1/3x−1/3x
5/3x+15≤0
Subtract 15 from both sides.
5/3x+15−15≤0−15
5/3x ≤ −15
Multiply both sides by 3/5.
(3/5)*(5/3x)≤(3/5)*(−15)
x≤−9
19500 times because
5 times 26 = 130 (how many minutes)
and
now just multiply how many minutes (130) times how many heart beats per minute (150) to get 19500
