Answer:
40
Step-by-step explanation:
6 x 7 = 42
8 ÷ 4 = 2
42 - 2 = 40
6 x 7 = 42
8 ÷ 4 = 2
42 - 2 = 40
What is the BODMAS rule in math?
The BODMAS rule follows the order of the BODMAS acronym ie B – Brackets, O – Order of powers or roots, D – division, M – Multiplication A – Addition, and S – Subtraction. The BODMAS rule states that mathematical expressions with multiple operators need to be solved from left to right within the order of BODMAS.
even if there aren't any brackets, the BODMAS rule is still used. We want to solve the other operations within an equal order. the next step after Brackets (B) is the order of powers or roots, followed by using division, multiplication, and addition, after which subtraction.

Terri is trying to save $250 so she can buy a new surfboard . She has \$75 saved already and plans to save $45 per week . How many weeks will it take her to save up enough money to purchase a new surfboard ?
Answer:
It will take Terri 4 weeks to save up enough money for a new surfboard.
Step-by-step explanation:
250-75= 175
175/45= 3.888
But its asking for whole weeks, so round to the nearest whole number, which is 4.
btw 45x4= 180 so she'll have 5 extra dollars.

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.

If there are twice as many square tables in the new rectangular table, why can’t twice as many chairs fit
around it?

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.

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.
