Which mathematical property is demonstrated 40•(25•74) = (40•25)•74

1 answer:

6 0

The mathematical property that allows 40 * (25 * 74) = (40 * 25) * 74 would be the Associative Property of Addition and Multiplication. This property means that no matter how the values of an expression are grouped together (or "associating" with each other), the end result will be the same, as long as the symbols are all either multiplication or addition symbols.
Hope that helped =)

Answer:

There are 9,999 positive whole numbers with 4 or less digits or less and one whole number which is neither positive nor negative.

This gives us 9,999+9,999+1 or 19,999 , whole numbers composed of 4 digits or less.

For a circle with a diameter

meriva

Answer:

The measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

Step-by-step explanation:

Here, the diameter of the circle = 6 m

Diameter = 2 x RADIUS

So, radius = D / 2 = 6 / 2 = 3 m

Also, the length of the arc = ( $\frac{5}{2} \pi$ ) meters

Putting π = 3.14, we get

The length S of the arc = $\frac{5}{2} \times (3.14) = 7.85$

or, S = 7.85 m

Let us assume the arc subtends angle Ф at the center of the circle.

⇒ S = r Ф

or, Ф = $\frac{S}{r} = \frac{7.85}{3} = 2.61$

⇒Ф = 2.61 radians

Now, 1 Radian = 57.2958 Degrees

⇒ 2. 62 Radian = 2.61 x ( 57.2958 Degrees) = 149.542 °

or, Ф = 149.542°

Hence, the measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

A stone is dropped into a well. the sound of the splash is heard 1.45 s later. what is the depth of the well?

Sav [38]

Answer: 14.21 m .
____________________________________
Explanation:
____________________________________

1.45 s * (9.8 m / s) = (1.45) *(9.8 m) = 14.21 m .
