Answer:
15 pieces
Step-by-step explanation:
a ratio of 1:3 has 4 total parts, meaning that each part is 5.
20/3 = 15 so that means he has 5 pieces of chocolate and 15 of hard candy.
The answer is choice D.
Cause it can't be calculate.

7). It is not possible. It is impossible.
An "acute" triangle is a triangle in which all three angles are acute.
"Acute" means "less than 90 degrees".
A "right triangle" has a 90-degree angle in it, so all three
of its angles can't possibly be acute.
8). Yes, Karen speaks the truth.
In an equilateral triangle, all three angles have
the same size, namely 60 degrees.
Studying this number astutely, you will notice that
it is less than 90 degrees.
Therefore, all three angles in an equilateral triangle are acute angles.
Therefore, every equilateral triangle is a cute one.
9). An equilateral triangle is one with all three sides the same length.
An isosceles triangle is one with two sides the same length.
A scalene triangle is one with all three sides different lengths.
You can drawum.
Answer:
1. Function
2. Not a function
3. Function
4. Not a function
Step-by-step explanation:
A function just means that for each input it outputs only 1 output. This output isn't necessarily unique. So for example if you're just given: f(2) = 3 and f(1) = 3, this is a function since each input only outputs 1 value, even though the output isn't unique, but if you're given: f(3) = 2, f(2) = 1, f(3) = 3. that's not a function since f(3) outputs both 2 and 3.
Anyways now that you hopefully understand this, let's look at each image.
Relation 1: (Function)
So for each input (the domain) it's only pointing to one output (range), even if multiple input (the domain) are pointing to the same output (the range), it's still a function.
Relation 2: (Not a function)
This is not a function, since if you look at the input 7 (the range), you'll see it outputs two things (range). It outputs -6 and -7. So this is not a function
Relation 3: (Function)
This is a function since each x-value (input) has only one y-value (output). So it's a function
Relation 4: (Not a functio)
This is not a function, since there are multiply coordinates with the same x-coordinate (input) and different y-coordinates (output). The x-coordinate 2 has the output b, y, and m, and since no value is given for these variables, it can be assumed they're different values, thus it's not a function.
