Answers

Answer 1

Answer:

11 x 2

Step-by-step explanation:

By BODMAS rule,

B - Brackets

O - Orders

D - Division

M - Multiplication

A - Addition

S - Substraction

Consider DMAS alone.

Here, there is no division.

So,

Multiplication ( x ) should be the first step.

B. [tex]9(\frac{4}{5} * \frac{1}{3})[/tex]

Step-by-step explanation:

In mathematics, the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

As the associate property is switching the numbers in the parentheses, B is the answer as it switched the [tex]\frac{1}{3} and \frac{4}{5}[/tex] while keeping the equation the same, and not editing any information that would change the outcome (answer) of the problem.

David begins the summer with a savings of $54.00 more than Fatima. David's job pays $8.25 per hour. Fatima's job pays $9.75. If they both work the same amount of time each day, how many hours of work will it take David to have as much money as Fatima? (write an inequality and then solve it)

Answers

Answer:

Inequality: 8.25x + 54 = 9.75

Step-by-step explanation:

Why?

It will take 36 hours for David to have as much as Fatima.

David :

Initial saving = 54

Pay per hour = $8.25

While Fatima :

Pay per hour = $9.75

Let number of hours worked = x

David's total = $8.25x + 54

Fatima's total = 9.75x

In other to have the same amount :

8.25x + 54 = 9.75x

The like terms :

8.25x - 9.75x = - 54

-1.5x = - 54

x = - 54 / - 1.5

x = 36

Therefore, it’ll take 36 hours for David to have as much as Fatima.

Answer:

36 hours

Round 38,451 to the nearest..
Ten thousand:
Thousand:
Hundred:
Ren:

Answers

Answer:

Ten Thousand: 40000

Thousand: 38000

Hundred: 38500

Ren: what is ren-?

Step-by-step explanation:

Ten thousand: 40,000

Thousand: 38,000

Hundred: 38,500

Ten: 38,450

When you round you have to look to the number to the right of the number your rounding.

For example, to round 38,451 to the nearest ten thousand you find the ten thousand place (3) and look to the right or it and find that number (8). It the number to the right is 5 or more you round up. If the number is less then 5 it stays the same.

Just try to remember this…

5 or more, raise the score

4 or less let it rest.

8 is greater than 5 so the 3 turns to a 4 and you make everything behind the 4 zeros.

Now let’s try 38,451 rounded to the thousand. Look to the right and see that the number is 4. 4 or less let it rest, so the thousands place (8) stays the same. But don’t forget to make everything behind it zero

Y=mx+c

Step-by-step explanation:

The number in front of the x is the gradient. This shows how much the line goes up in the y axis for every square in the x axis. The number after the plus is the y intersect. This is where the line crosses the y axis. Start at the y intersect and draw the line. For this question, the gradient is 2, so the line goes up 2 squares on the y axis for every square on the x axis. The y intersect is 1, so it would cross the y axis at +1 on the y axis

Lin is paid $86 for 4 hours of work how much would she be paid at this rate for 9 hours of work?

Answers

Answer:

173.5

Step-by-step explanation:

The answer is 173.5

To solve this type of equation we first have to find the unit rate, in this case, the unit rate is dollars every hour, in order to find this we have to divide 86 by 4 as shown below

[tex]86/4=21.5[/tex]

Therefore the unit rate is 21.5$ every hour so in order to find how much money she was paid after 9 hours we have to multiply 21.5 by 9, which is shown below

[tex]9x21.5=173.5[/tex]

Thus, that is how much money Lin will be paid after 9 hours of work.
