Answer:
125
Step-by-step explanation:
that would be , by proportion. 5 * 800 / 32
= 125 students
1)
c^2 < a^2 + b^2 = acute
<span>c^2 > a^2 + b^2 = obtuse</span>
<span>c^2 = a^2 + b^2 = right</span>
so
c^2 = 47^2 = 2209
a^2 + b^2 = 20^2 + 34^2 = 400 + 1156 = 1556
<span> 2209 >1156</span>
c^2 > a^2 + b^2 = obtuse
answer is B. obtuse
2)
<A = 90, <B = <C = 45
AC = AB = 12
12^2 + 12^2 = 2 (12^2)
BC = 12√2
answer is C. 12√2 ft
3)
a square cut into 2 equal triangles (2 isosceles triangles)
So it's 45 45 90 right triangle
if hypo = 34 then side = 17√2
answer is C. 17√2 inches
Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5
