Answer with explanation:</h2>
Let x denotes the number of days and y denotes the total change in gas price ( in dollars).
Given : During the past seven days the price of regular gas is decreased by $0.2 each day.
Rate of decrease =$0.2 per day
Then , Total change in gas price = Rate of decrease x Number of days
i.e.
i.e. 
(1)
To find the total change in gas price in 7 days , we put x= 7 in (1) , we get
Hence, the total change in gas price in 7 days = $1.4
Answer:
(320 ÷ 50) × 100
Step-by-step explanation:
if you divide 320 by 50, you get what a single percent of the original price would be. So to get the original price, you just need 100 of the singular percentages, which you can get by taking a singular percentage (320 ÷ 50) and multipoint it by 100
For a definite answer, let us take a look at the given circle graph. You are given that landing on a blue sector will give 3 points, landing on a yellow sector will give 1 point, purple sector will give 0 points and red sector will give -1 point. You are asked to find the probability of landing -1, 0, 1 and 3 points. There are a total of 7 pie graphs in the circle.
For -1 point, you know that only a red sector will give you a negative one point. In the circle graph, there are two red portions. So you will have a probability of 2/7.
For the 0 point, you know that only a purple sector will give you zero point. In the circle graph, there are two purple portions. So you will have a probability of 2/7.
For the 1 point, you know that only a yellow sector will give you one point. In the circle graph, there are two yellow portions. So you will have a probability of 2/7.
For the 3 points, you know that only a blue sector will give you three points. In the circle graph, only one blue portion is shown. So you will have a probability of 1/7.
Answer:
m = -18
Step-by-step explanation:
6 + m/2 = -3
Subtract 6 from each side
6 + m/2 -6 = -3-6
m/2 = -9
Multiply each side by 2
m/2 * 2 = -9*2
m = -18
Answer:
Yes, it can.
Step-by-step explanation:
To know if you can fill all the water balloons with the tank, the first thing is to calculate the volume of each one.
Volume of the tank, is a cylinder, whose volume is given as follows:
Vc = Pi * Rc ^ 2 * h
The radius of the cylinder has a value of 12 inches and the height of 20 inches. Thus:
Vc = 3.14 * (12) ^ 2 * 20 = 9043.2 inches ^ 3
Now, the volume of each globe that is a sphere is given by the following equation:
Ve = (4/3) * Pi * Re ^ 3
Being the radius of the sphere of 2, we have to:
Ve = (4/3) * 3.14 * 2 ^ 3 = 33.5 inches ^ 3
Now to know if you can fill all the balloons, we calculate the volume ratio of the tank and a balloon.
Vc / Ve = 9043.2 /33.5 = 269.95
Therefore, it can fill the 250 balloons because it has the capacity to carry approximately 269 balloons.
