Answer:
y=4x
Step-by-step explanation:
Two variables have a proportional relationship if the ratio of one variable to the other is constant.
A proportional relationship between x and y can be modeled by the equation y=kx.
The letter k is the constant ratio of y to x. It is called the constant of proportionality.
The ratio for each pair of x- and y-values is 4. So, the variables have a proportional relationship.
So, the constant of proportionality is 4 ounces of almonds per ounce of dark chocolate.
The equation for the relationship is:
y=4x
Answer:
v = 39.2 m/s
Step-by-step explanation:
They gave you the equation for velocity during freefall in picture2 as:
v = 9.8t m/s
they ask you what the value of v (velocity) is after t=4 sec.
Just plug in t=4 into the equation.
v = 9.8t
v = 9.8(4)
v = 39.2 m/s
<span>The temperature of water in a glass if room temperature is 21 degrees Celsius if a glass is standing one in that room, because room temperature is commonly given as 20 to 22 degrees Celsius, however, if the air in the room goes through temperature variations,then a body of water will heat up or cool down,then the temperature of the water in the glass tends to average out those temperature variations.</span>
To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
45-32 = 13 / 32 *100= 40.625 round to the nearest percent is 41%
Answer:
$20.70 increase per week!
Step-by-step explanation:
multiply 690 * 0.03 (aka 3%) to get 20.7 which equals $20.70
if you want to know how much she made the next week altogether, add 690 + 20.70 to get $710.70!
