Answer:

Step-by-step explanation:

Here, we want to select the possible table of the given line

Let us look at the intercepts

On the x-axis, we have an intercept at x = 2

On the y-axis, we have an intercept at y = -4

This means that when y = 0, x = 2 and when x = 0, y = -4

Looking at the options, the table that supports this answer is the table of option D

Find the length of the side of a square whose area is equal to the area of a rectangle with side measures 4.9 m and 1.6 m

trapecia [35]

Given :

Area of square equals to the area of rectangle of sides 4.9m and 1.6m .

To find :-

The side of the square .

Solution :-

As we know ,

Area = side²
4.9 * 1.6 = a²
a = √ 49/10 * 16/10
a = 7/10 * 4/10
a = 28/100
a = 0.28 m

The gear ratio of two gears is the ratio of the number of teeth of the larger gear to the number of teeth of the smaller gear. I

VLD [36.1K]

Answer:

24 gear.

Step-by-step explanation:

It is given that $Gear A:Gear B=Gear B:Gear C$ .

$\dfrac{Gear A}{Gear B}=\dfrac{Gear B}{Gear C}$

Gear A = 36 teeth

Gear C = 16 teeth

Let gear B have x teeth.

$\dfrac{36}{x}=\dfrac{x}{16}$

On cross multiplication we get

$36\times 16=x\times x$

$576=x^2$

Taking square root on both sides.

$24=x$

Therefore, gear B have 24 teeth.

Answer:

5040

Step-by-step explanation:

This is a problem of permutation where one has to arrange all the letters of the word taken all at a time. Since in N lettered word if all the letters are different then it can be arranged in N! ways i.e factorial N ways.

In the problem mentioned given

Word : Musical

number of words = 7 (all the words are different)

Number of ways to arrange it = 7!

7*6*5*4*3*2*1 = 5040

Hence 5040 is the answer!
