We need to write a proportion to solve this
7/3=35/x
105=7x
divide each side by 7
15=x so, there were 15 burgers without cheese.
We could add the cheese burgers 35 to burgers without cheese 15
35+15=50 burgers were sold.
Answer:
the duration of the flight be 1 hour
Step-by-step explanation:
The computation of the duration of the flight is shown below:
Let us assume the duration of the flight be x hours
Now the equation would be
600 ÷ x - 600 x + (1 ÷ 2) = 200
600 ÷ x - 1200 ÷ 2x + 1 = 200
x(2x + 1) = 3
2x² + x - 3 = 0
(2x + 3)(x - 1) = 0
x = 1 hour
hence, the duration of the flight be 1 hour
The same is to be considered
(a) There are 1/4 cups of flour per serving
<u>WORK:</u> 1.5/6=1/4 (change 1 1/2 into decimal)
(b) <u>**not sure**</u> There are approximately .18 cups of sugar per serving.
<u>WORK:</u> 9/2+4/12=13/12 and then divide 13/12 by 6.
(c) You need 2 1/4 cups of flour to make 9 servings.
<u>WORK:</u> 1.5/2=.75
1.5+.75=2.25=2 1/4
(d) Someone would need to know the amount of sugar to properly make the recipe and if needed know how much to put if you wanted to split the recipe.
Ahh good ole calculus. It’s been awhile. I think you plug in 9 for k and you should get 2(4)^9-1, which equals 2(4)^8. The only option would be your first.
