35/4 square meters by 7/2 meters

Answers

Answer 1
Answer: Area = 35/4  m²

Length = 7/2 m

Area =  length * width

35/4 =  7/2 * width

7/2 * width = 35/4

width = 35/4 ÷ 7/2

width = 35/4  × 2/7 = 5/2

Width = 5/2 m

What is 4/9 divded by 1/3

Answers

Easiest way is to flip the divisor and multply.

4/9 divided by 1/3
is the same as 4/9 times 3/1

Should be pretty easy to go the rest of the way yourself.

a/b divided by c/d=a/b time d/c
the reason it works is

you have
( (4)/(9) )/( (1)/(3) )
fractions in the denomenator is scary
make it one
remember that a/b times b/a=1 so 1/3 times 3/1=1
times the whole thing by 1 to keep is same
( (4)/(9) )/( (1)/(3) ) times ( (3)/(1) )/( (3)/(1) )=
( ((4)/(9))((3)/(1)) )/( ((1)/(3))((3)/(1)) )=
( (12)/(9) )/( (3)/(3) )=
( (12)/(9) )/( 1)=
12/9=4/3

reault is 4/3






Bill says he can add 23 and 40 without regrouping. Is bill correct? How do you know?

Answers

Answer:

Step-by-step explanation:

Yes bill is correct because both numbers are easy to add without regrouping, since when each of the digit are added there won't be carried over. Also, I believe Bill should be able to do simple mathematics like 2+3, 3+5 and so on.

Then, he should be able to add 3 plus 0 in his head and keep the result as 3. And then add the other 2+4 and he will put the two result together as 63

Yes Bill is correct because
3+0 you don't have to regroup
And 4+2 you don't have to regroup
hope this helps

Ann is opening a new savings account with an initial deposit of $250. Which combination of a deposit and a withdrawal will result in a zero balance in Ann's account? A) Deposit $20 in the first week and withdraw $270 in the second week.
B) Deposit $270 in the first week and withdraw $20 in the second week.
C) Deposit $20 in the first week and withdraw $250 in the second week
D) Deposit $250 in the first week and withdraw $20 in the last week.

I don't get this pls help me!!!

Answers

The combination of a deposit and a withdrawal will result in a zero balance in Ann's account is

A) Deposit $20 in the first week and withdraw $270 in the second week.

What is a saving account?

A savings account is a basic type of financial product that allows you to deposit your money and typically earn a modest amount of interest. These accounts are federally insured up to $250,000 per account owner and offer a safe place to put your money while earning interest.

Given that, Ann is opening a new savings account with an initial deposit of $250, we need to find the combination of a deposit and a withdrawal will result in a zero balance in Ann's account,

So, if Ann deposit $20 in first week the account balance = 250+20 = $270

Now, since the amount in her account is $270, so to make it zero, she should withdraw all the amount i.e. $270

Hence, the combination of a deposit and a withdrawal will result in a zero balance in Ann's account is

A) Deposit $20 in the first week and withdraw $270 in the second week.

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11. Check the students work, and use the check to find the error in the solution

Answers

There is an error in the student's work, the remainder should be 10

Further explanation

The division operation is one of the basic arithmetic operations

Common signs used are \large{\boxed{:}}} or \large{\boxed{\slash}}

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

\large{\boxed{\bold{divident:divisor=quotient+remainder}}

example:

7: 3 = 2 + 1

  • 7 = dividend
  • 3 = divisor
  • 2 = quotient
  • 1 = remainder

Division operation statement:

"7 divided by 3 equals 2 remainder 1"

The form of division can also be expressed in terms of fractions

In the example above, the form of mixed fractions  :

\displaystyle (7)/(3) =2(1)/(3)

Mixed fractions consist of whole number and proper fractions

From the task

(see also the attached image)

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11.

Division operation statement:

"878 divided by 31 equals 28 remainder 11

Arithmetic operations :

878 : 31 = 28 + 11

  • 878 = dividend
  • 31 = divisor
  • 28 = quotient
  • 11 = remainder

Because Division is the opposite of multiplying, so we check the solution with multiplying

divident - (divisor x quotient) = remainder

878 - (31 x 28) = 11

878 - 868 = 11

10 ≠ 11

So students make mistakes in subtraction operations,remainder should be 10
