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 you have powers in this fashion, all we need to do is multiply the two to get our answer.
Now we can solve:
2 x 2 x 2 x 2 x 2 x 2
4 x 4 x 4
16 x 4
64

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

Which ordered pair would form a proportional relationship with the point graphed below?
Answer:
-10, 20 because -20, 40 divided by 2 = -10, 20
The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:
(15, -30).
What is a proportional relationship?A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.
The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:
y = kx.
The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.
The constant for this problem is given as follows:
k = 40/-20
k = -2.
Hence the equation is:
y = -2x.
When x = 15, the numeric value of the equation is given as follows:
y = -2(15)
y = -30.
Hence the point is:
(15, -30).

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.

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.

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.
Answer:
x = 11(13/14)
Step-by-step explanation:
3/5(x – 7/10) = -31/4
open the bracket:
3/5 * x – 7/10 = -31/4
3/5 * –7x/10 = -31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10
167/20 = 7x/10
cross multiply:
140x = 1670
x =1670/140
x = 11(130/140)
x = 11(13/14)
The value of x is 1/5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3/5 (x − 7/10)= −3 1/4
Now, Solving for x
3/5 ( x- 7/10 )= 13/4
x- 7/10 = -13/4 x 5/3
x- 7/10 = -65 /12
x= -65/12 + 7/10
x= 24/ 120
x= 1/5
hence, the value of x is 1/5.
