Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
(Btw the answer to 249 X 398 = 63,672 )

When multiplying two numbers the two numbers being multiplied can SOMETIMES be called factors. This is not typically what factors are referring to.
When multiplying a negative number and a positive number the product is ALWAYS negative
An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?
Answer:
You can purchase 10 songs after buying 12 videos.
Step-by-step explanation:
Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.
Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.
Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.

how can you find the product of positive and negative decimals
(I have attached an example for reference)
1) Product means multiply, so we will multiply the decimal numbers.
2) First multiply both the numbers just the way you multiply two whole numbers.
3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.
4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.
5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

The Wing Station wants the average price of the lunch meal deals to be $8.
What does the price of the chicken wings need to be for this to happen?
Step-by-step explanation:
To calculate the mean, we do the the total divided by the number of values. With 6 values, for the average to be 8, the total needs to be 48. The current total is 41, so Chicken Wings needs to be 7, because 48-41=7

Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

[[Please explain]] The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters. Which equation relates the mass of the object, m, and the length of the spring, s?
O s=3/10m
O s=10/3m
O s=3/10s
O s=1/30s
Answer:
The required equation is [tex]s =\frac{3}{10} m[/tex]
Step-by-step explanation:
Given: The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.
To find : Which equation relates the mass of the object, m, and the length of the spring, s?
Solution :
Let the mass of the object m,
Length of the spring s,
When a 30-gram object is attached, the spring stretches 9 centimeters.
i.e, the times length of the object is attached to spring is The length of a spring varies directly with the mass of an object that is attached to it.
According to question,
i.e, length of the spring is 3 by 10 times the mass of the object.
Therefore, The required equation is

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤
Answer:
y=5x-1/4
Step-by-step explanation:
The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.
Answer:
The calculation to your equation is:
Y=5x-1/4
