Answer:
The two equations can you use to find the adult and child admission fees for a puppet show are and
Step-by-step explanation:
Let a represent the fee for adults
Let c represent the fee for children.
On day 1 number of adults = 45
So, fees of 45 adults = 45a
On day 1 number of children= 30
So, fees of 30 children = 30c
Total collection on day 1 = 315
So, equation becomes :
On day 2 number of adults = 50
So, fees of 50 adults = 50a
On day 2 number of children= 40
So, fees of 40 children = 40c
Total collection on day 2 = 370
So, equation becomes :
Thus the two equations can you use to find the adult and child admission fees for a puppet show are and
Hence Option C and E is true.

Answer:
The meet at first time at starting point after 336 seconds,
Vanu have completed 7 laps while Tanuj has completed 6 laps.
Step-by-step explanation:
Given that Venu and Tanuj take 48 seconds and 56 seconds to
complete a lap respectively.
To meet them again at the startiong point, the time taken must be multiple of 56 and 48.
So, the minimum time required to meet them again at the startiong point is time taken for first time meet.
Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.
Number of laps by Venu
Number of laps by Tanuj
Answer:
Length of the line segment RS is, 18 cm.
Step-by-step explanation:
Two points are drawn on a ruler. Point R is located at 8 cm and Point S is located at 26 cm.
So, length of the line segment RS is,
(26 - 8) cm\
= 18 cm
We know that on a ruler if two points A and B are at a cm and b cm respectively, then, length of AB
= AB = cm .
Answer:
Step-by-step explanation:
A direct variation equation is of the form
y = kx,
where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.
We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is
d = kw and we need to find k in order to have the model for dosing the animals.
Divide both sides by 1/30 to get k alone.
and
Our model then is
This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.
