Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.

Answers

Answer 1

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 )

Answer 2
First do 2times3 and then add 4 0’s because they are in the hundreds place and each of them have 2 0’s then do 9times4 and add 2 0’s to the answer and then do 9times8 add up all the answers :)

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear equations are:

2x+3y=8

6x−5y=−32

3X(2x+3y=8)

6x + 9y = 24

6x−5y=−32

14y =  56

y = 4

x = -2

Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

During the period 1800-1900, 6 out of the 23 u.s. Vice Presidents later became U.S. presidents during the period 1901-200 7 out of 21 presidents later became presidents. During which period did a greater fraction of Vice Presidents become presidents?

The relative ease with which the United States dispatched the Spanish squadron in Manila Bay was only the beginning of what would become a nearly 50-year American presence in the Philippines. It was one thing to capture the islands, but another thing entirely to set up a working administration. The Philippines encompasses about 7,100 islands and sits nearly 8,600 miles away from Washington, DC ...

Step-by-step explanation:

You can solve this in more than 1 way. The easiest way to solve though is by diving.
Step one: create a fraction
6/23 1800-1900
7/21 1901-2000

Step Two:
Divide the fractions. (Divide the numerator by the denominator, top by bottom)
6/23 ≈ .26
7/21 ≈ .33

From here you can see that 7/21 is greater because it has a greater number. I hope this helps!

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.


Mikey knows that the inequality representing this situation is 112 + x ≤ 260.


Select from the drop-down menu to correctly interpret the solution of this inequality.

Mikey's family can drive_____more miles before they need to refill the gas tank.

A. at most 148
B. at least 148
C. more than 372
D. more than 372

Answers

Answer:

A

Step by step:

you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.

Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

As per the given situation, the required inequality would be as

⇒ 112 + x ≤ 260

To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.

⇒ 112 + x  - 112 ≤ 260 - 112

⇒ x  ≤  148

This indicates that the maximum distance that may be traveled before filling up is 148 miles.

Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Part A: What is f(3)? Explain what this value represents in the given context.

Part B: Tina said that a possible range for the given function is y > 0. Based on the given scenario, do you agree or disagree? If you agree, explain why the range is correct. If you disagree, what values should be the range for the given scenario?

Answers

The range for the given scenario is y≥0.

Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.

Part B: Tina said that a possible range for the given function is y > 0.

From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.

Therefore, the range for the given scenario is y≥0.

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.

Answers

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

5,300
