Answer:
He made 40 grams of 20% sugar syrup.
Step-by-step explanation:
Alan threw 8 grams of sugar into 32 grams of water and got 8 + 32 = 40 grams of sugar syrup.
To determine the percent of sugar, note that
40 g - 100%,
8 g - x%,
then

Answer:
B
Step-by-step explanation:
8-5=3, 1-(-7)=8, 3^2+8^2=73, and the square root of 73 is 8.5
Answer: The student is <u>not</u> correct
To reflect over the y axis, you use this rule

The x coordinate swaps in sign (from positive to negative, or vice versa) while the y coordinate stays the same.
So for a point like A(1,1), it should move to A ' (-1, 1) and not (-2,1) like the diagram shows.
B(3,1) should move to B ' (-3, 1)
C(1,4) should move to C ' (-1, 4)
It appears that the student applied a reflection over the y axis, and then they shifted the triangle 1 unit to the left.
Answer:
200
Step-by-step explanation:
170% of x = 680
Set up an equation:
170/100 • x/1 = 680
1.7 • x = 680
1.7x = 680
x = 400
50% of 400
1/2 • 400 = 200
