394.6 divided by 9 using compatible numbers to estimate the quotient?

Answers

Answer 1

Answer: 394.6 / 9 = 43.84

Compatible numbers:

400 / 10 = 40

Compatible numbers are numbers that can quickly be solved mentally. The quotient would only be an estimate since we only rounded the number to the nearest compatible number.

394.6 is nearer to 400 while 9 is closer to 10. Both numbers 400 and 10 are compatible because they can be solved quickly doing mental calculations.

a square piece of paper is folded in half vertically. if the resulting figure has a perimeter of 12 cm, what was the area of the original square?

Answers

The area of original square is 16 centimetre square.

What is an area?

The area is the region bounded by the shape of an object.

Let consider 'a' as the side of the original square.

When it fold vertically then the top and bottom sides will be half of the original side.

The perimeter of folded square = 12 cm

i.e. (2* 0.5a)+ 2a =3a =12 cm

Then, a=4cm

The area of original square is given by a^2.

Then, a^2 = 4*4 =16

Hence, 16 centimeter is the area of the original square.

Which expression is equivalent to 2(m − 5) + 6?2m − 1

2m + 22

2m − 4

2m + 16

Answers

The expression that is equivalent to 2(m - 5) + 6 is 2m - 4. Option C is correct.

The given algebraic equation consists of numbers, arithmetic operations, and variables. The first thing to do is to open the brackets. After that, we will sum up or subtract the like terms.

Given that:

= 2(m - 5) + 6
= 2m - 10 + 6
= 2m - 4

Therefore, we can conclude that the expression that is equivalent to 2(m - 5) + 6 is 2m - 4.

Melanie made a circular necklace. She puts beads evenly spaced around the necklace. If the 4th bead is directly across from the 11th head, how many beads are on the necklace

Answers

If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total beads.

14 in total beads ...

What is multiplication?

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

Given that there are 3.25 dozens of eggs. The number of the eggs will be calculated as below:-

There are 12 numbers in a dozen. To calculate the number of eggs multiply the numbers 3.25 and 12.

Number of eggs = 3.25 x 12

Number of eggs = 39

Therefore, the number of eggs in 3.25 dozen will be 39.

Hi,

One dozen of eggs = 12 eggs.

$3.25\cdot 12 =(3+0.25)\cdot 12=3\cdot 12 +0.25\cdot12=36+\frac{12}4=36+3=39\;eggs.$
