Answer:
18 quarts.
1.875 quarts.
100÷3
Step-by-step explanation:
Step 1: How much sparkling water would you need to mix with 9 quarts of grape juice?
sparkling
water grape juice
1.5 3/4
X 9
we know that 9÷0.75 = 12 and 9×12 = 108
Hence we would need 18 quarts of sparkling water.
Step 2 : how much grape juice would you need to mix with 3.75 quarts of sparkling water?
sparkling grape juice
water
1.5 3/4
15/4 1.875
1.875 can also be expressed as 1(7÷8) this ÷2 or (1÷2) we get the answer.
you would need 1(7÷8) quarts of juice.
Step 3 :How much of each ingredient would you need to make 100 quarts of punch
=200÷3 for sparkling water
=100÷3 for grape juice.
100×3 = 300.
Step-by-step explanation:
Y=-0.5x²+1.25
To find the vertex we need to write given equation in the vertex form.
y=a(x-h)²+k
(h,k) - coordinates of the vertex
y=-0.5x²+1.25 can be written as
y=-0.5(x-0)²+1.25
So, h=0, k=1.25
Vertex is (0, 1.25)
For the fraction 28/10,
times 10 at 28 and 10,(to get the same denominator"100")
28×10=280
10×10=100
Thus,
28/10 become 280/100
We can plus the number above the denominator"100",which is 39 and 280.It is because they have achieved a same denominator.
39/100+280/100
=(39+280)/100
=319/100
