Offering brainlyest!! Find the Volume of each cylinder using 3.14 for π and rounding to the nearest tenth:
Answer:
7. 45.24
8. 114.51
9. 115.92
10. 105.62
Answer:
7) 45.21
8) 114.5
9) 115.9
10) 105.6
Step-by-step explanation:
Volume of a cylinder is πr^2h
Substitute the values of 3.14 for π.
r = radius which is 1/2 of diameter
h = height
Round the answer to one place after the decimal (tenth place)
If the statement 4 > 3 is true, which of the following are true about the relationship between –4 and –3? Check all that apply.
–4 < –3
The inequality changes from greater than to less than because -4 is less than -3.
–4 > –3
The greater than inequality holds true even when the opposites of 4 and 3 are used.
–4 = –3
(50 points)
Step-by-step explanation:
The first statement is true (-4<-3)
if u take the first statement (4>3) and divide by -1 you have -4<-3( because when u divide by a negative number the < > changes)
Mrs. Gonzales has only $63.50 to spend at a clothing store. She wants to buy a shirt that costs $28, including tax, and some bracelets that cost $4.50 each, including tax. PART A: Choose an equation to determine x, the maximum number of bracelets Mrs. Gonzales could buy. plz help ill give 40 points
Answer:
Mrs. Gonzales can buy a maximum of 7 bracelets.
Step-by-step explanation:
A shirt costs $28 total.
Bracelets cost $4.50 each total.
Mrs. Gonzales has $63.50 in all, assuming she wants to spend all of it.
Set the equation, let bracelets be denoted by the variable, x.
4.50x + 28 = 63.50
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:
4.50x + 28 (-28) = 63.50 (-28)
4.50x = 63.50 - 28
4.50x = 35.50
Next, divide 4.50 from both sides of the equation:
(4.50x)/4.50 = (35.50)/4.50
x = 35.50/4.50
x = ~7.89
However, note that you cannot round up, as you are buying. You also cannot buy .89 of a bracelet, so round down.
x = 7
Mrs. Gonzales can buy a maximum of 7 bracelets.

The area is 2 times the radius times the circumference.
True or False?
Answer:
I believe its true
Step-by-step explanation:
You have to find circumference of a circle. Pi comes here because of its ratio. 2 and r comes because it equals the diameter. So pi times 2 times r is basically circumference over diameter times diameter which gives circumference.
Hope this helps

Today, we will model a problem that happens in restaurants every day: moving tables together so that
everyone in a group can sit together. Use the square tiles to represent square tables. One person can sit along
each edge of a table side, no crowding. Our first goal is to find how many people can sit at tables made of
various numbers of square tables pushed together end to end.
How many chairs can fit around one square table? What is the perimeter of the square if the edge length is
one yard? Record the results in your table.

If two square tables are pushed together to form a longer rectangular table, how many chairs will fit around
the new table? What is the perimeter of the rectangle? Record the results in your table.

Make sure that each student can connect the square model on the desk to the picture on the classwork sheet.
If there are twice as many square tables in the new rectangular table, why can’t twice as many chairs fit
around it?
No chairs will fit right where the tables come together.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given are the values of {a} and {b}.
We can complete the third row as -
- a = - (- 6) = 6- 4b = - 4 x - 1/2 = 2- a + b = 6 - 1/2 = 5.5a ÷ ( - b) = - 6/(1/2) = - 12a x a = 36b x b = 1/4The complete third row is -

During a snowstorm, Alang tracked the amount of snow on the ground. When the storm began, there was no snow on the ground. For the first 2 hours of the storm, snow fell at a constant rate of 1 inch per hour. The storm then stopped for 6 hours and then started again at a constant rate of 3 inches per hour for the next 5 hours. Make a graph showing the inches of snow on the ground over time using the data that Alang collected.

EX 6: During a snowstorm, a meteorologist tracks the amount of accumulating ... the first three hours of the storm, the snow fell at a constant rate of one inch per hour.
Step-by-step explanation:
The graph representing the data collected by Alang is plotted and is attached at the end of the answer.
What is Graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given is a data collected by Alang which gives us the information about the amount of snow on the ground.
We can plot the graph to represent the same situation, Firstly, we will arrange the data in a systematic order. The following table gives the information about the rate of snowfall and the time period.
Snowfall Rate [R] Time period [T]
1 inch/hr 2 hr
No Snowfall 6 hr
3 inches/hr 5 hr
Now, in the graph -
X - axis represents the time period [T].
Y - axis represents the Snowfall Rate [R].
The graph is plotted and is attached with the answer. It can be seen that for the first 2 hours, the graph is a straight line at y = 2. Then for the next 6 hours, the y - coordinate remains zero (coinciding with x - axis). Finally, for the last 5 hours, it represents a constant rate of 3 inches/hr.
Therefore, the graph representing the data collected by Alang is plotted.
