17.4 x 1.0 Will the product be less than 17.4, equal to 17.4, or greater than 17.4? 17.4 × 0.98 Less than 17.4 Equal to 17.4 Gre
nikdorinn [45]

Answer:

1) Equal to 17.4

2)Less than 17.4

Step-by-step explanation:

One thing we must always remember that when we have number 0 after the decimal point, it means we do not need to consider that as it will have no effect on product and on the other operations.

So,

1)

17.4 x 1.0 = 17.4 x 1 = 17.4  (Product is equal to 17.4)

2)

Suppose if a number 'A' which is less than 1 is multiplied by any other number 'B', than the multiplication always result in the number less than B.

For example:

1x0.5 = 0.5 which is less than 1

Similarly for

17.4 x 0.98 = Result will be less than 17.4 as the second number is less than 1.

Product is less than 17.4

Select the correct answer<br> Solve this equation<br> X+4/6x = 1/x
laila [671]

Answer:

A) x = 0, 2

Step-by-step explanation:

(x + 4) / 6x =  1 / x

this is a proportion, so you can cross-multiply and get:

x(x + 4) = 6x

x² + 4x = 6x

x² - 2x = 0

x(x - 2) = 0

x = 0

x - 2 = 0  so, x = 2

Find the value of "c" by completing the square.<br><br>h²- 16h + c​
Sunny_sXe [5.5K]

Answer:

c = 64

Step-by-step explanation:

(a-b)² = a² - 2ab + b²

h²- 16h + c​

So, 2ab = 16h

2 * h * b = 16h    {as a =h}

b= 16h / 2h

b = 8

c = b² = 8*8 = 64
