I am not going to answer each but here is a general answer.
y is total price and x is number of kids
Sandy's equation would be y= 10+5x
Kimmi's equation would be y= 25
For them to equal we would have 25=10+5x
Simplify
5x=15
x=3
So for them to be equal, Sandy should have 3 kids.
So if someone has 5 children then he should choose Kimmi
Answer:
44.58m
Step-by-step explanation:
9.58+11+15+9 (Perimeter is adding all the sides around)
Y = 5x + c , ( -2 , -3 )
- 3 = 5 ( - 2 ) + c
c = 7
y = 5x + 7
i am a mathematics teacher. if anything to ask please pm me
Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.
