Answer:
998.
Step-by-step explanation:
Just get rid of the negative sign
Blackberries 1
blueberries 2
rasberries 3
strawberries 4
if you have to choose 1 of the 4 then your fraction is
(1/4)
1/4 = 25%
so the probability of you choosing the right one is 25%
i hope this is easy to understand and helps a lot
From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"
y^2 + b^2 = a^2
y^2 + c^2 = x^2
y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2
a^2 - b^2 + c^2 = x^2
Now put in the values given for a,b,c to solve for x
(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x
I would say answer chose C
-$12.99
That should be it, hit me up for any additional questions
