Answer:
2√6
Step-by-step explanation:
find the hypotenuse of the triangle thats 3 and 7
pythagorean
3 squared + 7 squared
16 + 49 = 57
√57 is the hypotenuse
√57 is also the base of the triangle that has side thats 9
pythagorean theorem
x squared + √57 squared = 9 squared
x^2 + 57 = 81
x^2 = 81 - 57
x^2 = 24
x = √24
x = √4 * √6
x = 2√6
Answer:
4÷7 is 0.571428571428571
= 0.57
Step-by-step explanation:
Hope this helps!!!
If he got the jeans for 40% off he paid 60% of the cost for the jeans. With that you can setup an equation.
20 is 60% of what number
is signifies equals and of signifies multiplication
20 = 0.6*x
x = 20/.6
x = 33.33
The regular price of the jeans is $33.33
Answer:
Table C
Step-by-step explanation:
To find the constant of proportionality, you need to divide y by x
Table A has a constant of proportionality of 
<em>which is 0.3333 repeating</em>
Table B has a constant of proportionality of 
<em>which is 0.6</em>
Table C has a constant of proportionality of 
<em> which is 0.3</em>
