Ivahew [28]

Answer:

Option B - 2

Step-by-step explanation:

We have given, the length of a spring when it’s at rest is measured to be 0.56 centimeter.

We have to find, how many significant figures are there in this measurement?

Solution :

The rules to get the significant figure are

Non-zero digits are always significant.

Any zeros between two significant digits are significant.

A final zero or trailing zeros in the decimal portion ONLY are significant.

The given measurement is 0.56 cm.

It has two trailing zeros in the decimal i.e. 5 and 6.

There are only two significant figures.

Therefore, Option B is correct.

The sum of two numbers is 66. Two times the smaller number is 15 more than the larger number. What are the numbers? First one wi

Viktor [21]

Answer:

Larger number (y) is 39

Smaller number (x) = 66 - 39 = 27.

Step-by-step explanation:

Let the smaller number be<em> x</em> and the larger number be <em>y</em>.

Sum of two numbers = 66

According to question,

<em>x </em>+<em> y</em> = 66

<em>x</em> = 66 - <em>y</em>.........(1)

Now, since twice of smaller number is 15 more than the larger number, According to question,

2(smaller number) = larger number + 15

2<em>x</em> = <em>y</em> + 15 .........(2)

Now substituting the value of y from (1) in (2)

2 (66 - <em>y</em>) = <em>y</em> + 15

132 - 2<em>y</em> =<em> y </em>+ 15

-2<em>y - y</em> = -132 + 15

3<em>y </em>= 117

<em>y</em> = 117/3 = 39

So the largest number (y) is 39

Smaller number (x) = 66 - 39 = 27.

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Schach [20]

The ratio will be same

Let width be x

$\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}$

$\\ \sf\longmapsto 3x=5(12)$

$\\ \sf\longmapsto 3x=60$

$\\ \sf\longmapsto x=\dfrac{60}{3}$

$\\ \sf\longmapsto x=20cm$

TanA × cosecA = secA

Rashid [163]

Step-by-step explanation:

L.H.S

tanA * cosecA

=sinA/cosA * 1/sinA

now cancel sinA and sinA

then,

1/cosA

= secA

= RHS

hence proved
