Compare and contrast the methods you can use to multiply a whole number and a decimal.

1 answer:

8 0

Here are the methods you can use when multiplying a whole number and a decimal. In multiplying a whole number, you can just do the normal multiplication process and the product would still be a whole number. In multiplying a decimal, it becomes different because the decimal points will affect the product. In multiplying decimal, each time we multiply by a power of 10, the decimal point is moved one place to the right. When multiplying a decimal by a whole number, placement of the decimal point is very important. When a given number has 2 decimal places, the product must also have two decimal places. Hope this explanation helps.

The formula for centripetal acceleration, a, is given below, where v is the velocity of the object and r is the object's distanc

julsineya [31]

Answer:

Step-by-step explanation:

For this case we have the following equation:

a = v ^ 2 / r

From here, we must clear the value of speed.

We have then:

v ^ 2 = a * r

v = root (a * r)

Answer:

the formula for the velocity is:

v = root (a * r)

Can someone help me in this question please be 100% correct it's a very important assignment

Arada [10]

For the first question, simply draw a horizontal line that has a middle number of 0. This is our number line. Then simplify plot the points.

For example, Furyk will be -3. Because he is 3 under par and par is 0.

For the second question, just find each person's score and line them up by size.

Furyk: -3
Woods: -6
Daly: +1
Couples: +6

Rearrange them by size.

-6, -3, 1, 6

And for the last question, Furyk would have a coordinate of (-3, 0).

So, the integers and the whole number would be the answer.

A. The perimeter of quadrilaterals are same when x=2.

B. The area of quadrilaterals are same when x=4.6

Step-by-step explanation:

A. Perimeter of the quadrilaterals must be equal.

Perimeter of square is 4a.
where, a = 6
Perimeter of rectangle is 2(l+b).
where, l = 2 and b = (3x+4)

Perimeter of square = Perimeter of rectangle

4(6) = 2(2+3x+4)

⇒ 24 = 2(3x+6)

⇒ 24 = 6x + 12

⇒ 6x = 12

⇒ x = 12/6

x = 2

For x=2, the perimeters of both the quadrilaterals are same.

B. Area of the quadrilaterals must be equal.

Area of square is a².
where, a = 6.
Area of rectangle is l $\times$ b.
where, l = 2 and b = (3x+4)

Area of square = Area of rectangle

(6)² = 2(3x+4)

36 = 6x+8

6x = 28

x = 28/6

x = 4.6

For x=4.6, the area of both the quadrilaterals are same.
