Answer:
2 out of 10 or 2/10
Step-by-step explanation:
1 brown shoes + 7 black shoes = 8
that means there were 2 other students wearing neither so out of the 10 students 2 weren't wearing black or brown shoes making 2/10
Answer:
f (x) = -2 (x + 6)^2 + 2
Step-by-step explanation:
f (x) = -2x^2 - 24x - 70 <--- divide out -2 out of the first two terms...
f (x) = -2 (x^2 + 12x) - 70 <-- divide the x coefficient by 2 and then square it, then add AND subtract it)
f (x) = -2 (x^2 + 12x + (12/2)^2 - (12/2)^2) - 70
f (x) = -2 (x^2 + 12x + 36 - 36) - 70 <--- distribute the -2 onto -36 to get it out of the brackets..
f (x) = -2 (x^2 + 12x + 36) + 72 - 70 <-- combine constants and factor perfect square trinomial...
f (x) = -2 (x + 6)^2 + 2 <-- standard form...
Answer:
h= 4.6, c=7.1
Step-by-step explanation:
First you need to know in a 30 60 90 triangle the sides ratios are x, 2x and x√3, and for 45 90 45 it is x, x and x√2
so <em>h</em> is 8/√3 and you rationalize the bottom so it becomes 8√3/3. when you solve this and round to nearest hundred it becomes 4.6. for the second one, it is 5√2 and when you solve this and round, it becomes 7.1

Answer:
A. 7 burritos for $51.50
Step-by-step explanation:
22.50/3=7.50
1 burrito cost $7.50
2 burritos will cost $15.00
2×7.50=15
5 burritos will cost $37.50
5×7.50=37.50
4 burritos will cost $30.00
4×7.50=30.00
However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
