You have to complete at least 10 physics problems and math problems within 2 hours before you playing video games. It will take

Ghella [55]

Answer:2

Step-by-step explanation:

Given

Physics problem requires 20 min

Math problem require 10 min

suppose x question of Physics and y questions of Math are done

so according to the question

$x+y\geq 10\ldots 1$

Time require for x Physics problem $=20 x$

Time require for y Math problem $=10 y$

so,

$20 x+10 y\leq 120\ldots 2$

On solving (1) and (2)

we get $x=2$ and $y=8$

Maximum no of Physics question which can be solved is 2

If Kayla has a red ribbon with length 25 9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?

Kayla has a ribbon of length = 25 9 m.
Part of ribbon give to Sania = 5 7 m.
So, the length of the ribbon left =25 9 m - 5 7 m = 175 63 = 130 63 m
So , the ribbon left with Kayla is 2.06 m .

Lulu wants to get fit. She started with 50 laps a day and she intends to add 10 laps every week. Write a mathematical expression

Bumek [7]

The mathematical expression for the given statement is 50 + 10x

<h3>How to write a mathematical expression for this statement?</h3>

The given parameters are:

Initial distance = 50 laps

Rate of increment = 10 laps each week

Represent the number of weeks with x

So, we have:

Number of laps = Initial distance + Rate of increment * Number of weeks

This gives

Number of laps = 50 + 10 * x

Evaluate

Number of laps = 50 + 10x

Hence, the mathematical expression for the given statement is 50 + 10x
