Step-by-step explanation:
Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 20 feet and a height of 16 feet. Container B has a diameter of 18 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.
The volume of water in container B to the nearest tenth of a cubic unit is 20.1 cubic units
How to determine the volume of water?This talks about the quantity or the amount of water the container B can hold after container A has been emptied.
We should note here that the volume of water in container B is the same quantity of water in container A.
This implies that Volume = πm(20)²(16)
Volume = 22/7 * 400 * 16
Volume = 140800/7
Therefore, the volume of water B can contain is 20.1 cubic units

Find equation of the line that passes through the point a and point b
A=(1,7) B=(-3,-1
)
Answer:
Step-by-step explanation:
The equation of the line can be found using the two-point form:
y = mx + b
where m is the slope between the two points and b is the y-intercept.
For the given points A and B:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) is point A and (x2, y2) is point B
m = (-1 - 7) / (-3 - 1) = -8/ -4 = 2
Next, find b using one of the points and the slope:
b = y - mx
b = 7 - 2 * 1 = 5
So, the equation of the line is:
y = 2x + 5

What is the difference between frequency table and a line plot?In a frequency table, the frequency at which each value appears in a data collection is used to summarise the data set. The frequency of data over a number line is depicted on a graph called a line plot. Data that is arranged numerically is referred to as organised data.
A line plot is a graph that shows information as dots or checkmarks above a number line, indicating the frequency of each value. The line plot, for instance, displays the quantity of ribbons in this case, broken down by length. Line graphs and plots of lines are frequently mistaken. Compared to a line graph, a line plot is distinct.

Define inequality.In mathematics, an inequality is a linking of two equations or numbers when there isn't an equal sign. Unbalance therefore precedes inequity. When two numerical values are not equal, an inequality results in a relationship between them. Egality and inequality are not the same. Where variables are not similar or equal, have used the most common symbol (). There are various inequalities that can be utilized to contrast values regardless of how small or huge they are. Switching the two sides it until variables represent all that is left can address a variety of basic inequality problems. The combination or division with low values from both sides are only a few examples of the many factors that might cause inequality. You switch sides and the left.

The weight of a basket containing 60 apples was 3 1/5 kg. An identical basket containing 40 apples weighed 2 and a half kilograms. It weighs 150 pounds.
Is an apple a gram or kilogram?The typical weight of an apple ranges from 150 g to 250 g. A 10 g error was discovered in the weight of each apple. The average weight of apples is calculated by dividing the total number of apples by the actual weight of the apples. Consequently, 10 apples actually weigh 62 g on average. As an apple is rather little, the measurement should be in grams.
Apples have a high fiber content. About 4 grams, or 17% of the Daily Value, of this vitamin may be found in a single medium-sized apple (100 grams) (DV).
