Answer:
Step-by-step explanation:
1.2307692307692.
The first step is to find the proportionality constant.
The formula is
z = kx/y
1.2307692307692 = k * 4/13 Multiply both sides by 13
1.2307692307692 * 13 = 4k
16 = 4*k Divide by 4
k = 16/4
k = 4
=================================
z = k*x/y
x = 9
y = 20
k = 4
z = 4 *9/20
z = 36/20
z = 1.8
The range is a set of elements from the second set.
Therefore your answer is:
<h3>D. { -4, 1, 7, 15 }</h3>
Answer:
X + (0.18 * X)
where X is the price of the bill without the tip
Step-by-step explanation:
The first thing you have to do is convert the percentage to a decimal value. For example, if it is 30%, its decimal value is 0.30. As simple as dividing that 300 by 100. Repeat the previous step with all the percentages you have to add.
In this case it is 18% therefore the decimal value will be 0.18. As we do not have the value of the account, we will call this value X .
Therefore the total price of the account, that is, with the addition of the tip is as follows:
X + 18% de X =
X + (0.18 + X)
Answer:
271.25 gal
Step-by-step explanation:
Assuming the tank is oriented so that the quantity of oil is proportional to depth, the amount remaining is ...
(3 1/2 ft)/(8 ft) × (620 gal) = 271 1/4 gal
