The value of y varies directly with x. When y = 3.5, x = 2.
What is the value of y when x is 16?

Answers

in order to do this problem, you have to divide 16 by 2 to see how many times x was multiplied. you would find that x was multiplied 8 times, so in order to find y, you would multiply 3.5 eight times.

I just need help on these two questions ​

Answers

Answer:

Q1) y= 2

Q2) y= 4

Step-by-step explanation:

Q1) If you sub in x as -1, 2 to the power of -1 is 0.5. You always solve the power first, not the multiplication. So then you do 0.5 times 4 and you get 2.

Q2) If you sub in x as 0, anything to the power of 0 becomes 1. 2 to the power of 0 is 1. Then you do the multiplication, 4 times 1 = 4

Solve. Dante's mom made 2 liters of cocoa. Dante and his 7 friends each drank a serving of cocoa. If each serving is 235 milliliters, how much cocoa is left?

Answers

Answer:

120 millimeters or 0.12 liters

Step-by-step explanation:

To solve this question :

we have to convert liters to millimetersmultiply the serving of coca by the number of people that consumed the cocasubtract the answer gotten from the step above from 2 litters

1 liter = 1000 millimeter

2 liters = 2 x 1000 = 2000mm

8 people drank cocoa = 8 x 235 = 1880mm

Amount of cocoa left over = 2000 - 1880 = 120mm or 0.12 liters
